SPECIFICATION forming part of Letters Patent No. 741,659, dated October 20, 1903. Application filed May 23, 1902. SerialNo.109, 623. (No model.)

To all whom it may concern:

Be itknown that I, CHARLES L. HAASE, J12, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Improvement in Gearing, of which the followingis a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates'togearing, and the object of the invention is to produce improvements in devices by means of which the movement transmitted from a motor or engine to the member or part to be driven may be varied or changed in speed or reversed in direction as is desired. This and other objects I attain in a device embodying the elements in its make-up constructed and arranged as described in the specification and illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of a device embodying this invention. Fig. 2 is a cross-sectional view of the same, taken on line 2 2 in Fig. 1. Fig. 3 is a cross sectional view taken on line 3 3 in Fig. 1. Fig. 4is an end elevation of a portion of the device. Fig. 5 is a sectional view of a portion of the clutch mechanism. of portions of the clutch mechanism.

' Throughout the severalviews like elements are denoted by like characters.

The device employs transmitting gearwheels, the complementary members of which are always in mesh one with the other, and the device comprises a driving gear-wheel adapted to be operatively connected to the engine or motor from which power is to be.

Figs. 6 and 7 are detail views wheels and a gear-wheel for each of said loosely-mounted gear-wheels and always in mesh therewith, and aslidable or'longitudinally-movable lever-actuating member carpanying drawings, is especially'designed for use on motor-propelled vehicles, such as automobiles,-and more particularly to automobiles propelled by internal-combustion'or socalled explosive engines, not capable of being readily started under load.

. With the device as a portion of the powertransmitting mechanism between the motor and the driving-wheels of the vehicle the engine or motor may be started Without load and run until its desired speed is attained. Then by moving the actuating-lever for the device to one of its predetermined positions the desired power will be transmitted to the sprocket-wheel and through the remaining transmitting mechanism to the driving-Wheels of the vehicle.

The device is adapted to be self-contained and the mechanism in its make-up supported within a dust proof oil containing casing formed in two sections 8 and 9, which have their abutting faces machined, so that a close fit may be obtained. The sections are bolted ,together by means of bolts which pass through holes 10 in section 8 and registering bolt holes in section 9, and when the sections are so bolted together holes 11, 12, 13 13, and14 14 will be drilled or bored through lugs 15,--

16, 17, 18, 19, and -20, formed therefor in the casing. I also will the holes 13 13 and the holes 14 14, and half of each of said holes will lie within each section 8 and 9. The casing is pivotally supported on the vehicle, on one side by The holes 11 and 12 will register, so

stud-pin 21, carried by any convenient portion of the vehicle, and'on the other side by a stud 22, carried by a portion of the vehicle, or on the engine frame or bed. The studpin 22 is bored out to receive and carry a projection 23 of the engineshaft, to the end of which is keyed a driving gear wheel or member 24, held onto said shaft by means of a suitable washer and a nut 25, threaded to said shaft. The casing is prevented from side movement by means of contacting with a shoulder 26, formed on stud -pin 21, and a shoulder 27, formed on stud 22. Each of the holes 13 is lined with a suitable antifriction sleeve orlining 28,formed of phosphor-bronze, Babbitt, or other suitable metal, and within these sleeves is journaled a rotatable shaft 29, to which at suitable positions are keyed gear- wheels 30, 31, 32, and 33, prevented from moving longitudinally of said shaft by means of sleeves or spacers 34, carried therebetween on the shaft. The holes 14 are lined with sleeves or bushings 35, similar to 28, but formed with flanges 36, adapted to lie within counterbores in theinner ends of holes 14, and a hollow shaft 37, designated as the driven shaft, is journaled within the sleeves. The outer surface of shaft 37 is formed in the nature of concentric steps 38, 39, 40, 41, 42, 43, and 44. The risers of steps 38 and 44 contact with the inner ends of sleeves 34 and 35, respectively, and prevent longitudinal movement of shaft 37. Step 39 loosely carries a gear-wheel 45, which surrounds the shaft and meshes with gear-wheel 30. Gear-wheel 45 is provided with a laterally-projecting annular flange 46, forming a friction-drum. Rigidly carried by shaft 37 on step 40 and secured thereto by means of a set-screw 47, Fig. 3, is a collar 48, provided with two disk shaped projecting faces 49 and 50.

An annular split friction-ring 51 is carried within the drum or flange 46 and is adapted when spread or expanded to contact with and grip the inner friction-surface of said drum. The ring 51 at its point of separation is provided with two radially-extending flanges 52, each braced to the ring by means of a web 53. The separated points of the ring or the flanges 52 when the ring is loose within the drum are adapted to stand a distance apart as shown in Fig. 2.

A rockable expander 54 for the expansible friction-ring 51, having concentric cylindrical bearing portions 55 and 56 of different diameters, a squared portion 57, connecting said bearing portions, and a flattened expander portion 58, adapted to lie between flanges 53 of said expansible ring, is journaled within holes therefor in disks 49 and 50.

An actuating-lever 59 for the clutch mechanism is formed with a bifurcated end, the furcate parts 60 and 61 of which are provided with concentric circular holes, the walls of which are adapted to loosely surround the expander 54. The lever 59 is carried by the larger cylindrical portion 56 of the expander and is provided with an angularly-projecting arm 62, adapted to project into the opening within driven shaft 37, through an opening 63 in collar 48, and an opening 64 in shaft 37 therefor.

A block 65, provided with a squared opening to fit the squared portion of the expander, is carried by the expander, and a set-screw 66, locked in adjusted position by a lock-nut 67, is threaded through an opening therefor in the block and bears against the lever 59 between the furcate parts thereof to limit the depth to which the projecting arm 62 of lever 59 will extend into the hollow driven shaft 37. The pressure of the expansible frictionring 51, acting on the flattened portion 58 of the expander through the radially-extending flanges 52, will tend to keep the projecting arm 62 toward the limit of its inward movement in the driven shaft, and as the projecting arm 62 is by means moved outward the expander will be rocked and ring 51 expanded or enlarged, and if arm 62 is moved far enough ring 51 by friction will be locked to drum 46. It will be seen that it the expanderring is locked to the drum and driving gearwheel 24 is rotated the driven shaft 37 will also be rotated by means of gear- wheels 30 and 45.

Step 41 of driven shaft 37 loosely carries a gear-wheel 68 in mesh with gear-wheel 31. A drum 69, provided with an annular frictionface similar to the friction-face of drum 46, is bolted or otherwise secured to gear-wheel 68. An expander-ring similar to ring 51 is carried within drum 69 and is adapted to be actuated by means of a lever 70 and the related elements similar to those heretofore described.

Separated from gear-wheel 68 by means of a spacer 71, carried on the driven shaft and loosely mounted on step 41, is another gearwheel 72 in mesh with gear-wheel 32. Gearwheel 72 is provided with a drum 73 and clutch mechanism similar to that heretofore described, adapted to be actuated by means of a lever 74, similar to lever 59. The lever and clutch actuating mechanism is carried by a disked collar 75, secured to step 42 ofshaft 37 and similar to collar 48.

Loosely mounted on step 43 of shaft 37 is a gear-wheel 76, adapted to be locked to shaft 37 through the medium of a clutch mechanism similar to that heretofore described, ac-

tuated by a lever 77.

A gear-wheel 78, Fig. 3, suitably journaled on a stud 79, carried by section 8 of the easing, meshes with gearwheels 76 and 33, so thatgear-wheel 76 will rotate in the same direction as gear-wheel 33 and in the opposite direction from driving gear-Wheel 24.

As heretofore said, the driven shaft 37 is formed with a hollow bore, and within this bore a slidable actuating member 80 for the levers 59, 70, 74, and 77 is located. This ICC slidable member in cross-section is shaped as shown in Figs. 2 and 3,with guiding- flanges 81 and 82 adapted to bear against the walls of the bore in the shaft. The slidable member is also provided with three laterally-projecting portions 83, 84, and 85, having inclined ends. As the slidable memberis moved longitudinally the lever- arms 59, 70, 74, and 77 are adapted alternately to ride up the inolined ends of the projections and rest on the tops thereof, which are curved concentrically to. the bore in shaft 37. Itwill be seen that by moving shaft or slidable member 80 to its different positions different levers may be moved out of the bore in the shaft 37 and caused to actuate their respective clutch mechanisms to lock the gear-wheels complemental thereto to the driven shaft 37. The forward portion of the slidable member 80 is cylindrically formed, so as to snuglybut movably fit the bore of the driven shaft.

The driven shaft extends beyond lug 19 and is cut down to receive a washer 86 and a sprocket-wheel 87, kept from turning on the shaft by means of a feather 88 enteringa slot therefor in the sprocket-wheel and a registering slot therefor in the shaft. The sprocketwheel is held against longitudinal movement on the shaft by means of a lock-nut 89, threaded over the outer end of the shaft and provided with a suitable locking means 90.

The cylindrical portion of the slidable member 80 is bored out to receive a connecting member 91, having a'cylindrical center portion 92, an enlarged cylindrical shoulder 93 at its inner end, and a stepped shoulder 94 at its outer end, the'smaller of said steps lying within the bore of the slidable member, while the larger of said steps serves to limit the movement of said slidable member into the driven shaft 37. The connecting member 91 is held within the slidable member 80 by means of a split sleeve 95, secured within the slidable member by means of a rivet-pin 96. The slidable member is provided with a slot or elongated recess 97,form ed therein beneath feather 88, and into which said feather projects to lock the slidable member 80 to shaft 37. The outer end of the connecting member 91 is provided with a hole 98 extending therethrough,-within which an actuating-rod 99 is adapted to slidably fit.

Section 8 of the casing is provided with a door or manhole 99 to permit access to the interior of the casing for adjusting the screws 66, and said door or manhole is adapted to be closed by means of a suitable plate 100.

Having thus described my invention, I
