STEPHEN M. BALZER, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGN- MENTS, TO BALZER MOTOR COMPANY, INCORPORATED, A CORPORATION OF DELAWARE.

SPECIFICATION forming part of Letters Patent No. 730,433, dated J une 9, 1903. Application filed December 17, 1897. Serial No. 662,327. (No model.)

To all whom it may concern.'

Be it known that I, STEPHEN M. BALZER, a citizen of the United States, residing in New York city, county and State of New York,`

have invented certain new and useful Imf-y provements in Gas or Oil Motors, of which the following is a specification. f

One object of. my invention is to provide improvements in rotary gas or oil motors; and to this end the invention Vembraces improve'-V ments in the construction of themain parts of the motor, to improved means for feeding a propulsive medium to the motor and for exhausting it therefrom, to improved means for causing a circulation of water around the y vide improved means for communicating different speeds from the motor to a driven part without altering the speed of the motor, and

in connection with this part of the invention I have shown the motor as applied to a vehi-y cle, whereby the same may he driven at varying speeds and also brought to a rest Without stopping the motor.

My invention also embraces the novel details of improvement and the combinations of parts, that will he more fully hereinafterv set forth and then pointed out in the claims. Reference is to he had to the accompanyingl drawings, forming part hereof, wherein- Figure l is aside elevation of a motor-vel hicle equipped with myimprovements. Fig. 2 is a plan view of the improvements, showing part of the framing thatsupports the device in a vehicle. Fig. 3 is a cross-section thereof. Fig. 3Ll is a partly sectional detail view of a shaft-support. Fig. 4 is a side elevation, partly broken, of the parts shown in Fig. 2. Fig. 4u isadetailface viewofa toothed sector-arm. Fig. 5 is-a partly broken side elevation of the motor orl casing and cylinders and connected parts. Fig. G is a detail view of a pump used in circulating water around the combustion and explosion chambers of the cylinders. Fig. 7 is a plan View, with the top removed, of the cylinder and explosionchamber. Fig. 8 is a vertical section on the plane of .the line 8 8 in Fig. 7. Fig. 9 is an inverted plan view of the casting 14 at the end of the cylinder. Fig. 10 is a partly sectional side detail View showing means for operating the gas andair valves. Fig. 1l is a similar view at right angles to Fig. l0, also illustrating the devices for operating the sparkers. Fig. l2 is an enlarged detail sectionalview of the gears and friction devices for communicating motion from the motor to a driven part or axle, and Fig. 13 is an enlarged detail sectional view on the plane of the line 13 i3 in Fig. l2.

In the accompanying drawings, in which similar numerals and letters of reference indicate corresponding parts in the several views, l indicates the main shaft of the n10- tor, having a crank 2, and in the example illustrated the shaft 1 is held from rotation by being secured to a suitable frame 3.

4 is a shaft supported by the frame 3 and held in axial alinement with the shaft l, the shaft 4 being rotative. The shafts l and 4 :perform the function of a single crank-shaft,

with this exception that one part is stationary and the other part is rotative. The shaft l is shown supported at its outer end by a universal joint, wherein cz is a ring mounted on shaft l and secured thereto bya key b, the ring a having pivots or lugs c, that are pivotally carried hy a ring d, which also has pivots e at right angles lo pivots c and pivotally connected with frame 3. The pivots c and c may be held on `the ring d and frame 3 by clampsf. (See Figs. 3 and 3a.) The shaft4 is shown provided with a hall 5, that is journaled iu a cavity in a bearing the bearing 6 hein g made in two parts'and bolted together, as usual. The bearing 6 is carried by frame 3. The shaft 4 passes through and is secured to the ball 5, and the openings in the bearing 6, through which the shaft passes, are larger than said shaft, whereby the bearings 6 and shaft 4 may have oscillatory or lateral Inovement. The movable supports for shafts l and 4 allow the frame 3 to have slight independeut movement, so that the shafts will not bind in their supports. (See Fig. 3.)

7 is a frame or casing of suitable construction and adapted to carry the cylinders and certain operative parts of the motor. The frame 7 is journaled on the shaft 1 and is rigidly screwed or otherwise secu red to the shaft 4, so that it may rotate on the former and carry the latter around with it.

8 is a Hy or balance wheel carried by frame 7, and it may be secured thereto by bolts in suitable manner or cast in a single piece therewith.

9 represents cylinders, which are carried by frame 7 and shown set at one hundred and twenty degrees apart and in line with the crank 2, so as to rotate around the latter. (See Figs. 3 and 5.)

10 represents pistons in the cylinders 9, and

A11 represents rods connecting the pistons with the crank-pin 2n. The pistons may be of suitable construction, and the rods 11 are preferably connected to said pistons by a balland-socket joint, as shown in Figs. 3 and 8. The rods 11 are shown provided with feet 11a, having curved ends that correspond to and fit against the periphery of the crank-pin 2a, (see Fig. 5,) and these feet are shown held upon said crank-pin by means of collarsor sleeves 11b, the width of the feet 11 being such that they can have oscillating movement on th'e crank-pin 2, (See Figs. 3 and 5.) Furthermore, the exterior surface of the feet l1a taper or slope toward the pin 2, and the collars 11 are adapted to slideupon these taper surfaces to enable proper adjustment of the feet 11:L upon pin 2 to hold said pin and feet together in proper operative relation and to take up wear. The collars 11b are held in position bylock-nuts 11, threaded on pin 2a. (See Fig. 3.) I have shown the shaft 1, crank 2, and pin 2a as provided with a bore and the pin 2"L has one or more lateral apertures leading to the feet 11 for the passage of lubricant from bore x.

The inner ends of the cylinders 9 are shown secured to the frame 7 and open into the interior thereof, and the outer ends of the cylinders are shown secured to the ily-Wheel 8 by means of bolts, (see Figs. 3 and 5,) the cylinders being shown provided with flanges 9a to receive bolts 9b. The cylinders J at their outer ends are connected with an explosionchainber 12 by a port 13. (See Figs. 3 and 8.)

The explosion-chamber l2 is formed as follows: From one side of the cylinder 9 at its outer end projects an extension 14, that is provided with a recess or opening 14, shown formed partially by an annular wall 14", the recess or opening 14 being shown provided with a cap 15 to permit access to chamber l2. The port 13 connects the bore of the cylinder 9 and the opening 14a and is located in extension 14. p

16 is a frame or casting having recess 16, that is formed by an annular wall 161, which registers with the wall 14", the opening 14a, and the recess 16, thereby forming the explosion-chamber 12. As shown, theV meeting edges of the walls 14b 16D are recessed to form overlapping joints to keep the parts centered and form a tight joint. The frame or casting 16 has an opening 17, adapted to receive the cylinder 9, and this frame is thus mounted upon the cylinder and is suitably secured thereto and is alined with extension 14. The frame or casting 16 has a main outer wall18, which passes around the cylinder 9 and incloses the walls 14b 16", thereby forming a water-jacket 19 in conjunction with the cylinder and the extension 14, against which the Wall 18 abuts, this water-jacket thus inclosing the upper end of the cylinder and the explosionchamber 12, as will be understood from Figs. 3, 7, 8, and 9, tight joints being made between the parts 14 and 18.

The propulsive medium, in the form of a mixture of gas or oil and air, is to be led to the chamber 12 and there ignited while under compression, and for this purpose I have provided the following arrangement: In the bottom wall of recess 16a of the frame or casting 16 are two apertures 20 2l, which lead to ports 22 23, provided in the frame 16, (see Figs. 7 and 8,) one of these ports being to admit gas or oil and air and the other for the exhaust, as shown, the port 22 beingadapted for fuel and the port 23 for the exhaust. To the port 22 is connected a tube 22n and to the port 23 is connected a tube 23a. The tubes 22a 23 lead to ports 24 25, respectively, that are provided in the frame 7, there being one of each of said ports in the frame 7 for each cylinder, and the ports 24 are adapted to receive gas or oil and air, and the ports 25 carry the exhaust. For this purpose I have shown the port 24 at one part as extending lengthwise of shaft 1 in an extension or sleeve 26, carried by frame 7. (See Fig. 3.) In said extension or sleeve are apertures 26, that lead to each port 24. Around the extension 26 and overlying apertures 26"L is a ring 27, provided with an interior annulan groove 27, alined with the openings 26, and this ring 27 also has an aperture 27b to receive gas and air from a feed-pipe 28'. 29 is another ring surrounding extension 7 and provided with an interior annular groove 29a, alined with apertures 25L in extension 26, that lead to the ports 25, that extend lengthwise of extension 26, and in this ring 29l is an aperture 29, that leads to an exhaust-pipe 30. Between the rings 27 29 and on the outer sides thereof is placed packing 31 to produce a tight joint, the packing and rings 27 29 being held in place by a suitable bushing 31A. These rings, the packing, and the bushing are inclosed withina bearing 32, having an annular bore to receive them, and this bearing has apertures 32 32h, that communicate with the apertures 2"b 29b and with the inlettube 28 and the-exhaust-tube 30, respectively. A suitable valve 33 is connected with the exhaust-tube 30 and arranged to prevent back pressure, while permitting the passage of the spent products of combustion. The exhausttube 30 leads, by preference, to a suitable water-tank.

IIO

The inlet-tube 28 leads to a suitable tank or reservoir 34, and the latter is provided with a suitable inlet having a cap or stopper 34 to prevent escape of gas or oil and an outlet-cock 34b for draining,and, by preference, I provide a tube 35, connected with the tank 34 at its lower part, and at its upper end said tube has a head 35, provided witha gauze 35i for the admission of air to the tank to prevent a vacuum forming, the gauze serving to break up the particles of air and preventing a noise. Thus the air is drawn up through the oil or .gasolene, causing a vapor to pass 'oft through pipe 28. 1 The tube or pipe 28 is provided witha valve 36 to regulate the passage of gas or oil from the tank 34 to the motor, and, by preference, this valve has an auxiliary opening 36 for the admission of air, so that a mixture of air and gas or oil may pass to the motor. The valvehas three ways to regulate the passage of gas or oil and air and to regulate the relative quantities of each that may pass in a Well-known manner.

It will be understood that as the motor rotates the ports 24 25 will be kept in connection with the inlet and exhaust tubes 28 30 and that the openings 20 21, connecting the ports 22 23 with the explosionchamber 12, are to be opened and closed asrequired, and it will be also understood that in the device illustrated the motor draws in a supply of fuel on one stroke and then compresses it at the outer end of the cylinder and in the explosion -chambcr, that thereupon the compressed fuel is ignited and pushes the piston, and that then the-piston returns and forces out the vspent products of combustion. To accomplish these results, I have provided the following arrangement: 40 is a valve fitting a seat formed at opening 20, and 41 is a valve correspondingly arranged for opening 2l, these valves being shown adapted to open into the explosion-chamber l2. (See Figs. 7 and 8.) 40L and 41n are valve-stems connected with valves 40 and 41 and guided in bearings carried by the frame or casting 16, these stems having heads or enlargements 401 41h, that receive springs 42 43, that bear against the frame 16 and-act to hold the valves to their seats. (See Fig. 8.) The valves 40 41 A are controlled through their stems by means of reoiprocative rods 44 45, that are actuated by cams 44a 45a, that are adapted to rotate around the shaft 1, these cams being placed in such position relatively to each other that one will open the gas-valve while the exhaust-valve is closed, and vice versa. I have shown the rods 44 V45 as provided with rollers 441 45h, adapted to bear upon said cams, and these rods are journaled insuitable bearings A on frame 7. 10, 1l.) Springs 44c 45C, surrounding rods 44 45, serve to hold the corresponding rollers upon the cams 44L 45, these springs being shown as located between a pin carried by the rod and part of the frame 7. (See Figs. 10, Il.) By preference the cams 44n 45 are (See Figs. 3,Y

vsecu-red tothe wall of chamber 12.

secured together, as by an ,intermediate hub 46, (see Figs. 2 and 3,) the cams and the huh 46 in the arrangement shown'heing made in a single piece of metal. Means are provided for rotating the cams by and during the rotation of the motor, and for this purpose I have shown a gear-Wheel 47, secured to the cam and in mesh with a pinion 48, that meshes with a gear 49, the latter being in mesh with a gear 50, secured to shaft 1. (See Figs. 3, 10, 11.) The gears 48 49 are mounted upon studs 48549, that are suitably secured to the frame 7, and the pinion 48 is of sufficient width to mesh with gears 47 49 at the same time, these gears being placed side by side, as will be understood from the drawings. The arrangement of these gears is such that the cam will rotate somewhat faster than the motor, so as to travel ahead to operate Vthe various valves 40 41 at the proper times. I have shown the hub 46, the cams, and the gear 47 as mounted to rotate upon a sleeve 51, that is journaled on shaft 1 and connected by a plate or arm 51 with frame 7. (See Fig. 3.)

To govern the speed of the motor, I have shown means to admit more or less air to the ports 24, and thus to the chamber 12. For this purpose port 24 in extension 26 opens at the end of the latter and is covered with a plate 24, provided with an aperture that receivcs a head or plug B, adapted to close said aperture. The outerend of head Bis tapered, so that when pushed inwardly into port 24 it will allow more or less air to enter said port. (See Fig. 3.) The head B is connected with a stem C, that is connected with a slide or sleeve D, mounted to travel on extension 26,

E is a rod guided in a lugF on slide'D and surrounded by a spring Gr, that bears against said lug and against part of frame 7 and acts to push the slide D outwardly. The slide D is further controlled by ball-governor arms II, that are pivotally carried by arms h, secured to extension 26, the arms H being movably connected with slide D. The arrangement is such that as the motor rotates the balls move outwardly, and thereby the arms H push the slideD toward frame'7, the head B being likewise moved, its tapered part allowing more or less air to enter port 24, and the greater the speed the more air will be admitted. The air passes to chamber 12 and reduces the richness of the fuel mixture, thus reducing the power and slackening the speed, and so on as the motor rotates.

The means I have shown for producing a spark at the proper time in the explosionchamher 12 are as follows: Within the chamber 12 is a stationary contact 52 and a movable contact 53, the latter being held normally in engagementwith 52 by a spring 53a. (See Figs. 7 and 8.) The contact-52 isshown The contacts 52 53 are to be electrically connected with a battery,(not shown,) and at the proper time lthese contacts are to be separated to TIO produce a spark. For this purpose I have shown a pin 54, carried by a head 54'L ona rod or shaft 55, that projects through a suitable stuliing-box in the bottom wall offrame or casting 16 and is adapted to rotate therein. (See Fig. 3.) The inner end of rod 55 projects between the cams 44a 45n and carries a pinion 56, (see Figs. 3and 11,) thatis adapted to engage teeth 57 58, shown carried by one of the cams, as 44, (See Fig. 11.) The arrangement is such that as the cams rotate ahead of the cylinders one set of teeth will first engage pinion 56 and turn it to bring the pin 54 about into engagement with contact 53 and will then pass from said pinion to allow it to come to rest, so that a complete closing of the circuit at 52 53 will be assured, and then the other teeth will engage the pinion 56, thereupon further moving pin 54, which will break the circuit at 52 53 and produce a spark. This arrangement will be of advantage under high rotation of the motor in that it will allow a sufficient time for the circuit through the contacts to be Well formed before a break is made,so as to assure a proper spark at each breaking of the circuit.

The circuit for producing a spark may be arranged in any suitable manner. I have shown an induction-coil J, from which the wire j leads to a brush K, carried by frame 3, which brush bears upon a commutatorring L, carried by casing 7, (see Fig. 2,) and from the ring L a conductor L2 leads to the contact 53, and the contact 52 is in electrical connection with the metal parts of the motor, the circuit extending thence to a battery which is connected with the coil J. Any suitable switch may be provided for making and breaking the circuit as desired.

The arrangement I have shown for causing a circulation of water in chamber 19 around the eXplosion-chamber 12 and the explosion.

end of the cylinder 9 is as follows: The wall 18 of chamber 19 is provided with an inlet and an outlet 61, to which tubes 62 63 are respectively connected. By preference the inlet 60 is connected with a tube 64, that is located within the chamber 19 and extends along the same around one part of cylinder 9 and well up to the Wall of explosion-chamber 12. (See Fig. 7.) By this means the cooling-water is delivered directly at the explosion-chamber 9 and passes out through the outlet 6l to tube 63.

I provide a pump to keep up a circulation of water in chamber 19, and this pump is operated by and during the rotation of the motor. The shaft 4 is provided at its inner end with a bore 65, the outer end of said bore being closed by a plug 66. (See Fig. 3.) The tubes 62 63 open into said bore, as shown in Fig. 3. Within bore 65 is located a tube 67, having heads 67 67h, which t closely Within said bore, and the tube 67 is of less diameter than the bore 65, said tube and its heads thereby forming two compartments, one being the compartment 69 and the other comprising the bore in the tube-62 and the spaces 68 70. The tube 62 leads to compartment 69, and the tube 63 leads to space 68, the spaces 63 70 being in communication through the bore of the tube 67, as indicated by dotted lines in Fig. 3, the compartment 69 being entirely separated from the other compartment. Mounted upon the shaft 4 is a casing 7l, adapted to contain the operative parts of the pump, and 72 is a cover or plate for said casing, which is bolted thereto and provided with a hub 72, having ports, as will be described, the shaft 4 also passing through said plate or cover and its hub. Suitable packing is provided between the parts 7l 72 72a and the shaft 4 to prevent leakage of water. (See Fig. 3.) The casing 71 has an extension 7l, having a bore or channel 71", that communicates at its outer end with a pipe or tube 73, that leads to a Water-tank 74, preferably passing through a stand-pipe 74, connected therewith. (See Fig. 4.) Within the bore or channel 7lb is a movable plug 75, that is adapted to reciprocate therein, which plug is provided with a bore 75a, which at its inner end projects sidewise at 75l. (See Fig. 6.)

76 is a spring within the bore or channel 7lb and pressing against a wall thereof and against plug 75, tending 'to force the plug toward shaft 4. The interior of the casing 7l is annular and concentric with shaft 4 in the form of an annular recess or chamber 71, that communicates with channel 71", one part of the wall of casing 7l being cut away at 71d. (See Fig. 6.) In the side wall of casing 7l is a groove 77, terminating on the side opposite the cut-away part 71d and communicating with an aperture 78 in the shaft 4, that leads to the compartment 69. Within the recess or chamber 7lc of casing 7l is a ring 79, that surrounds the shaft 4 and is located eccentrically to said shaft. (See Fig. 6.) From the shaft 4 pins 8O 81 project in opposite directions, and these pins pass through apertures in the ring 79, and 82 is a spring surrounding the pin SO and pressing against shaft 4 and against the ring 79, thus serving to hold one part of the ring in contact with the inner Wall of chamber or recess 71c of casing 7l. (See Fig. 6.)

IOO

IIO

From the foregoing it will be understood l.

that as the shaft rotates in the direction of the arrow in Fig. 6 the ring 79 will be carried around with it, and as the plug 75 is in contact with said ring and the ring moves in an eccentric paththe plug 75 under the inuence of the ring 79 and the spring 76 will be reciprocated, thereby forming a movable wall to divide chamber 71C; also, that when the high part of the cam is in contact with the edge of channel 71d the flow of water into the chamber 7lc will be cut o, and that thereupon as the cam-ring rotates it will force water ahead of it and out through channels 77 7S and the plug 75 will advance to deliver Water behind said ring, at the same time actby ring 79, the ring acting to suck or draw water through the bore in plug 75, and as the ring advances toward channel 71d it will gradually move plug 75 back and stop the inflow of water. It will thus be seen that a rotary pump is provided which is actuated bythe rotation of shaft 4 and that the water forced by the pump is delivered through channels 77, 78, and 69 to tube or pipe 62 and through pipe 64 into the chamber 19 of frame or casing 16,the water passing from there through pipe 63 to the chamber 68 a'nd thence through the bore in tube 67 to the chamber 70. The chamber 70 communicates through au opening 70a with an annular recess or channel 83 in the hub 72a. This recess or channel 83 is connected by a pipe 84 with the tank 74, passing into the stand-pipe 74", as in Fig. 4. Thus it will be understood that asthe pump operates it draws water from'the tank 74, forces it through the chamber 19 to cool the explosion-chamber and the end of cylinder 9, and the water then passes through the bore in shaft 4, hub 72, and pipe 84 back to the tank 74. It will be understood that pipes 62 63 from each cylinder extend to chambers 68 69.

In Fig. 3 I have shown the pump-casing and its hub as surrounding a sleeve or boss 85, that projects from agear-Wheel 86, which sleeve or boss has openings to aline with the openings 78 and 70*- in the shaft 4, and it is also provided with suitable openings to receive the pins 81 and 82, the gear-wheel 86 being mounted upon and secured to shaft 4.

The gear 86 is for the purpose of transmitting.

power from the motor.

The parts so far described constitute a complete rotary motor from which power can be transmitted in any suitable manner, it being understood that shaft 1 may be suitably held to enable the frame7and the parts connected therewith to rotate; but it will be also linderstood that if the frame 7 and the cylinders are held stationary the shaft 1 would be rotated and that power could be transmitted therefrom.

In order to enable varying speeds tov be transmitted from the motor without checking the speed of the same, and, furthermore, in order to apply a motor to a vehicle or roadwagon, I have provided means for transmitting power at varying speeds from the motor to the .axle or wheels of such vehicle, and in connection therewith I utilize friction devices to prevent undue strain upon the gearing, particularly in changing from one gear to another. In the arrangement I have shown I have provided for three speeds-a high, a low, and an intermediate speed. In addition to the gear-wheel 86there are secured upon the shaft 4 gears 87 88, the arrangement shown being such that gear 87 will produce a high speed, gear 86 an intermediate speed, and gear 88 a low speed or power. The gear S7 meshes with a gear 89, the gear 86 with a gear 90, and the gear 88 with a gear 91, the

'gears 89, 90, and 91 being loosely mounted upon a shaft 92, which is suitably supported in bearings on the frame 3. Upon the shaft 92 is mounted a pinion 93, which meshes with a gear 94, that is adapted to rotate a driven part, such as an axle or shaft 95, with which said gearis properly con nected. As the gears 89 90 91 are loosely mounted upon shaft 92, I have provided friction clutches or devices for connecting .either one of such gears with the shaft and for disconnecting them therefrom to allow the motor and the driven shaft or axle 95 to move independently, and in connection therewith I have provided a frictionbrake for checking the momentum of the vehicle or the driven part 95, the arrangement I have shown being as follows: Rigidly mounted upon shaft 92 is an'armor extension 96, projecting outwardly from said shaft in two directions and which may be secured thereto by a spline and feather. 97 is a friction drum or disk having an internal bore or socket 97a, this` disk or drum having a central'bore to receive the shaft 92, upon which it is loosely mounted. To the drum or disk 97 is secured gear-wheel 89, being shown secured thereto fby screws 89, the principal reason that the gear 89 is separate from the friction disk or drum 97 being that said gear is smaller in diameter than said drum and is therefore easier toconstruct in this manner; but. it is evident that the parts 89 and 97can be constructed in a single piece of metal. Vilhin the bore 97fL of the friction drum or disk 97 is located a split friction-ring 98, that is shown carried by a pin 99, projecting from support 96. A pin 100, also carried by the support 9b', projects laterally therefrom and carries an arm or finger 101, one portion of which is located between the ends 98a 98" of the friction-ring 98, as shown in Fig. 13, so that when arm 101 is turned on its pivot it -will expand the ring 9S into frictional engagement with the friction disk or drum 97,

whereby as the gear 89 is rotated the parts 97, 98, 96, and 92 will be driven thereby.

The means I have shown for expanding ring 98 through the medium of arm or lever 101 consists of a,pin 102, carried by said arm and project-ingl into the bore of shaft 92 through an aperture 103 in said shaft. (See Fig. 13.) For the purpose of enabling adjustment of pin 102 I have shown it in the shape of a screw threaded into a suitable aperture in arm 101, and to lock it firmly to said arm I have shown said arm split longitudinally at 102a and provided with a screw 104,threaded in the two members thus formed, so to expand or contract the members of said arm to lock the pin 102.

105 is an aperture passing through the friction drinn or ring 97 and the split ring 98 to permit the passage of a tool to adjust the threaded pin 103. lVithin the bore of shaft 92 is a longitudinally-movable rod or presser 106, that is adapted to act upon pin 102 to force the same outwardly in order to turn the arm 101 on its pivot to expand ring 98,

i and for this purpose the rod 106 is shown provided with an annular enlargement107, having a beveled or cone-like surface 1072, adapted to ride against said pin to actuate the same. (See Fig. 12.) Theeulargement 107 is shown of a sufficient size to fit snugly within the bore of shaft 92, and the rod 106 is i suiciently small so that it will not operate pin 102.

In order to^ drive gear 90 frictionally, an arrangement similar to that just described with reference to Figs. 12 and 13 is provided, in which a friction drum or ring 90"L is connected with gear 90, in the arrangement shown the parts 90 and 90n being made in a single piece of metal bored out to receive a Split ring 90b, that is supported on pin 99, and 101 is an arm carried by pin 100 and located between the ends of ring 90b and provided with a pin 108, these parts being substantially similar to parts 98 99 v100101 102 and acting in the same manner, the pin 108 passing through an aperture in shaft 92 to be engaged by the enlargement 107 on rod 106. Thus if pin 102 is operated by parts 106 107 gear 89 will drive shaft- 92; but if pin 108 is operated by parts 106 107 gear 90 will drive said shaft and at a dierent speed from that produced by gear 89. It will also be seen that enlargement 107 is not adapted to engage pins 102 and 108 at the same time, but may pass between said pins and is cone-like on opposite faces. Gear 91 is provided with adrum orring 91, the parts being counterbored to receive a split ring 109, that is supported on a pin 110, carried by an extension or disk 111, secured to shaft 92, as by a spline and feather, and an arm 112 is carried by a pin 103, supported by extension 111, the arm 112 having a pin 114,

the parts being substantially similar to thev arrangement shown in Fig. 13. Upon rod 106 is an enlargement 115, having its opposite sides beveled or cone-like and adapted to ac t upon pin 114 to cause gear 91 to be frictionally connected with shaft 92 in manner described with relation to parts 89 97, &c. Thus the shaft 92 may be frictionally driven at three different speeds.

In order to resist the rotation of shaft 92, I have shown a friction disk or drum 116 secured to frame 3 and provided with a bore 117, in which is located a split ring 118, supported on pin 110, and between its ends is an arm 119, supportedon pin 113 and provided with a pin 120, adapted to be acted upon by enlargement 115 of rod 106, (see Fig. 12,) all in manner similar to that shown in Fig. 13 and described with relation to parts 89 97, e., the arrangement being such that when enlargement of rod 106 operates pin 120 the split ring 118 will produce frictional engagement with friction-drum 116, and thereby retard or prevent the rotation of shaft 92.

. The distance between pins 114 and 120 is such that enlargement 115 may rest between them without operating either, and the arrangement is such that after enlargement 115 has passed pin 120 and the rod 106 is moved farther said enlargement will engage pin 114 to frictionally connect shaft 92 with gear 91. If a higher speed is desired, rod 106 will be moved.(to the left in Fig. 12) until enlargement 115 releases pin 114 and enlargement 107 engages pin 108, whereupon gear 90 will be frictionally connected with shaft 92, and if a still higher speed is desired rod 106 will be moved (to the left in Fig. 12) until enlargement 107 releases pin 108 and engages pin 102, whereupon gear 89 will be frictionally connected with shaft 92. It will be understood thatif shaft 92 is rotating at either speed and it is desired to throw olf the gear it will only be necessary to move rod 106 far enough to release the pin with which its enlargement is in engagement. At any time that it is desired to apply the brake it is only necessary to move rod 106 (to the right in Fig. 12) until enlargement 115 comes into engagement with pin 120, and although either or both enlargements on rod 106 may pass over one or more of saidA pins in the meantime no ill eects will arise.

A ny suitable means may be provided for moving rod 106 longitudinally back and forth. The arrangement I have'shown for the purpose is as follows: Upon one side rod 106 is provided with a series of teeth 121, which are cut in the form of a worm and are adapted to receive corresponding teeth 122 on a sectorlike arm or lever 123. (See Figs. 4 and 12.) These teeth 122 on arm 123 are shown in face View in Fig.' 4f, in which they are placed at an acute angle to a line passing through the longitudinal center of the face of arm 123, and the arrangement is such that as arm 123 is rocked forward or backward the teeth 122 will act upon the teeth 121 to slide the rod 106 longitudinally. To keep rod 106 from rotating under the action of arm 123, I have shown said rod as provided with a spline 106, adapted to receive a feather or projection 124 at the end of an arm 125, secured to frame 3. (See Fig. 12.) The arm 123 is pivotally hung upon a stud or shaft 126, carried by frame 3, and 127 is a lever or arm secured to arm 123, whereby the latter may b e rocked upon its pivot. For the purpose of enabling lever 127 to be brought into convenient position to be operated by the occupant of a vehicle when the devices before described are applied to a vehicle without altering the position of arm 123 relatively to rod 106 I have shown the outer face of hub 123a of arm 123 provided with teeth 128, that are adapted to mesh with teeth 1281, carriedby the hub 127 of lever 127, screws 129 being provided to hold the parts 123 and 127 together. (See Fig. 12.)

In order to start the motor-shaft 4, it has to be rotated by hand, and for this purpose I have shown the shaft or stud 126 as tubular and its bore located in line with shaft 4 to enable a suitable crank or handle 'to be attached to said shaft within or through the IIB bore of shaft or stud 126.l (See Figs. 3, 4, and 12.) Said shaft is shown provided with a pin 130, upon which a crank or handle (not shown) may operate to tu rn said shaft in Well-known manner.

In applying my improvements to a vehicle any suitable frame therefor maybe provided. In the drawings Ihave shown a vehicle composed of tubing to which the frame parts 3 are attached for supporting the motor, and the tanks or receptacles for oil-and water are suitably carried by said vehicle. While the gear 94 may be suitably connected with axle 95 or drive-Wheel 95, I have shown an arrangement for equalizing the axle 95 to enable the vehicle to convenientlyturn corners, as follows: The shaft 95 at one end carries a sleeve 131, which is adapted to rotate independently of said shaft (see Fig. 3) and is to be attached to the hnbof wheel 95a. Snitable bearings 132 133 are provided and carried by the frame of the vehicle, the sleeve 131 being adapted to rotate in the bearings 133, and for this purpose said sleeve is shown provided with cones 134 to act'with the friction-balls of the bearin g. gear 94 is movably attached to shaft 95, and to said shaft is also attached a bevel-gear 135, and to the sleeve 131 is attached a corresponding bevel-gear 136, the gears 135 and 13.6 being located' on opposite sides of gear 94 and adjacent thereto. (See Figs. 2 and 3.) The gear-Wheel 94 carries one or more bevel-pinions 137 133, that mesh with the gears 135 136 at the same time. (See Figs. 2, 3, 4.) For this purpose I have shown the gear 94 provided with shafts 139 140, upon which the pinions 137 138 are respectively mounted.

In order to permit the ready attachment and removal of the shafts 139 140 to and from the gear 94, I have shown the hub of said gear provided With apertured lugs 141 142, adapted to receive the forked ends 1391 140 of shafts 139 140, said-forked ends of the shafts being provided with apertures to receive pins that pass through them and through the apertured lugs, and the outer ends of said shafts are held between clamps 143 144, secured to the spokes of the gear-wheel 94. (See Figs.. 3 and'4.) The arrangement is such that as gear 94 is rotated and shaft 95 is traveling in a straight line the pinions 137 will act upon gears 135 136 uniformly, so as to carry said gears around in the same direction and at the same speed; butif the ve- .hicle is turning from a straight line one of its wheels will travel faster than the other, and thereupon said pinions 137 138 will act upon the gears 135 136 in such manner that said gears may rotate at diierent speeds, in which event the pinions will cause one of said gear-wheels to rotate faster lthan the other, at Which time said pinions will have independent movement on their axes, at the same time causing axle or shaft 95 to continue to rotate. n

The operation of the motor is as follows (See Fig. 3.) The Thel inlet fonthe fuel is opened, thecircuit for the sparkers is closed, and the motor is started by first rotating the shaft 4. The piston in one cylinder moves toward the crank and draws in a supply of fuel in the form of a mixture of gas and air, filling the cylinder and its explosion-chamber12 during one halfrotation, during which time the corresponding inlet-valve 40 is opened by the action of its cam 44, During the next half-rotation the piston moves outwardly and compresses the charge in the chamber 12 and the outer end of the. cylinder, during which time the rod 55 is turned to bring its pin 54 near contact 53, and thereupon when the piston is and three pistons, a similar action will take place in each, and as the cams rotate faster than the cylinders they Will travel ahead, so as to cause the corresponding valves 40 and 4l and the sparkers of each cylinder to operate successi velyand at the proper time. arrangement is such that there will be three explosions to tWo revolutions of the casing 7 the difference in speed between the casing 7 and the cams enabling the latter to advance so as to operate from cylinder to cylinder to produce the necessary operations of taking in, compressing, exploding, and exhausting the charges for the diierent cylinders.
