MOTOR-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 581,816, dated May 4, 1897. Application filed March 14, 1896. Serial No. 583,220. (No model.)

To (bZZ whom it may concern:

Beit known that we,ROBERT J. GIBBONS and MARGARET A. WILcoX, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in M0- tor-Vehicles,of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improvement .in motor-vehicles; and it consists in improved means for starting the operating mechanism of the carriage, for changing the speed of the same, and for applying the brakes, t me.

The invention also consists in the details of construction, as hereinafter described and then definitely claimed at the end hereof.

In the accompanying drawings, which indicate the preferable ways of carrying out our improvement, Figure 1 represents a longitudinal vertical section of our improvement asapplied to a vehicle. Fig. 2 represents a plan view of the same. Fig. 3 is a detail of a portion of the driving-power. Fig. 4 represents a detail of another portion of the driving mechanism. Fig. 5 is a detailed view of part of the steering apparatus. Figs. 6, '7, and 8 are detailed views of an automatic starter.

The views as above described are drawn to different scales for the purpose of better illustrating the details of the vehicle.

Referring now to the details of the drawings by letters and figures, A represents the working cylinder of gas-engine which forms the motive power for the vehicle, and working in this cylinder is a piston a, whose piston-rod a is secured to a crank B, which crank is formed on a horizontal shaft C, and said horizontal shaft transmits motion, by means of frictional gearing hereinafter described, so as to operate the driving-shaft D, on which the driving-wheels E E are secured. This gas-engine is supplied with gas from a gas-generating apparatus 1, which consists of a reservoir or tank wherein the oil is held and evaporated by a vacuum caused by suction strokes of the engine, which gas after being generated is mixed with air, which enters through a small inlet made in a valve 2, when the gas and air are ready for use in the gasengine.

charged by a battery X, placed under the seat of the vehicle, as shown in Fig. 2.

It might be well to state that the cylinders of the engine have water-jackets Z and waterpipes Z, through which water is kept in circulation to prevent said cylinders from becoming unduly heated.

Connected to the horizontal shaft C is a flywheel F, from which rotary motion is transferred to a supplemental shaft G by means of a friction-wheel H, slidingly secured to said supplemental shaft G, and which frictionwhcel bears on the fly-wheel F. On each end of the supplemental shaft G is a sprocketwheel I, through which power is transmitted to sprocket-wheels J on the driving-shaft by means of the sprocket-chains K K.

The friction-wheel II, which has just been described as bearing against the fly-wheel F, is slidingly secured to the supplemental shaft G, and in order to change the location of this friction-wheel II, so asto get greater speed when it contacts near the periphery of the fly-wheel B, or greater power when it contacts near the axle of said iiy-wheel, we provide a yoke L, whose arms Z Z bear on each side of the hub of said friction-wheel II, and at the bottom of the yoke is an antifriction-roller L, which travels in a guide M. Secured to the arm Z of the yoke is one end of a chain N, which chain passes over a guide-pulley n and around a sprocket-wheel N, and is then continued around two other guide-pulleys n n, and then has its other end attached to the other arm Z of the yoke.

The parts just described are operated when the sprocket-wheel N is caused to rotate, and the friction-wheel H may thus be caused to travel back and forth on the supplemental shaft G, so as to change the speed of the vehicle in a manner which will be easily understood.

S forms the seat of the vehicle, and immediately in front of this seat is a standard 8, from which the shafts of the wheels 0 and P project. The inner wheel 0 is secured to a shaft 0, on the lower end of which is secured a sprocket-wheel 0, from which power is conveyed to another sprocket-wheel 0 on a shaft 0 by means of a sprocket-chain 0 On the other end of this shaft 0 is a bevel-gear 0 which through its companion gear 0 transmits motion to a shaft Q, and on the rear end of this shaft is secured the sprocket-wheel N, before referred to. On the shaft Q is also secured a bevel-gear g, which through the bevel gear q operates the shaft qiwhich shaft when turned opens or shuts the valve 2, heretofore referred to. The operation of these parts is as follows: WVhen the wheel 0 is turned, the shaft Q is operated through the sprocketwheels,sprocket-chain, and bevel-gears above described, and as this shaft Q rotates the shaft g is operated through the bevel-gears q q and causes the valve 2 to open, thus allowing gas and air to enter the engine to operate the piston in the usual manner. Simultaneously with the opening of the valve 2 the shaft Qalso operates the sprocket-wheel N, which causes the chain N to move the friction-wheel H, as hereinafter described. As the Vehicle commences to move, the wheel 0 is turned further, which allows a larger supply of gas and air to pass through the valve to the engine and at the same time moves the friction-wheel H farther from the axle of the fly-wheel F, and as more and more gas is admitted to the engine the frictionwheel is caused to travel nearer the periphery of the fiy-wheel B in order to get the greatest amount of speed.

Of course it is understood that when the wheel 0 is turned backward in order to close the valve 2 to shut off the supply of gas the frictional wheel 11 is moved back to its original position. lVe wish it to be also understood that the parts are so arranged that the valve is opened fully before the friction-wheel H travels to the end of its outward movement in order that said friction-wheel may be moved back and forth to some extent without changing the supply of air and gas, so that the engine may be driven at practically the same speed whether the vehicle is traveling on a level or on a slight upgrade, the additional power required for the upgrade being given by moving the friction-wheel H nearer to the axle of the fly-wheel, which would of course give more power to the vehicle, but of course run the same at a slower speed, although the engine is running uniformly all the time.

The valve 2,above mentioned,is so arranged that when it is shut it may be opened by turning the shaft-(1 in either direction, and as the shaft continues to rotate the valve is opened wider until it is opened to its full extent. This construction is made to enable the friction-wheel H to be moved either side of the center of the fiy-wheel, in order that the direction of rotation of the supplemental shaft G may be reversed, in order to move the vehicle backward.

It will thus be seen that when it is desired to move the Vehicle backward it will be unnecessary to reverse the engine and that all it is necessary to do is to rotate the wheel 0 in a backward direction until the frictionwheel H is moved to the opposite side of the fly-wheel B, when the rotating parts of the vehicle are run in the opposite direction. The brakes are also operated by the same parts which open the valve 2 and control the position of the friction-wheel H, and said brakes and their operating mechanism may be described as follows:

T. T represent the brake-shoes, which bear against the tires of the driving-wheels, and which brake-shoes are connected with the brake-beam T. This brake-beam is connected by means of a link t with a lever T whose function will be described later. Firmly secured to the supplemental shaft G is a disk U, and slidingly secured to the same shaft is another disk U, and between which disks is a loose pulley U and this loose pulleyU is connected with a strap or chain U which passes around pulley u and is connected to the above-mentioned lever t". The shaft (1 carries a cam a, which when the shaft g is operated at the proper time turns against an L-shaped lever 2?, whose other end operates the disk U on the supplemental shaft G. Thus it will be seen that when the shaft g is operated to close the valve 2 it also turns the cam it against the lever a andforces the slidingly-secured disk U against the loose pulley U and holds the loose pulley by friction against the pulley U. This causes the loose pulley to move as the supplemental shaft G rotates, and as said pulley U rotates it winds up the strap or chain U and moves the lever T which movement, through the link i, operates the brake-beams T and forces the brake-shoes T against the driving-wheels and stops the vehicle.

The above-mentioned wheel P has a hollow spindle P connected thereto, through which the above-mentioned shaft 0 of the wheel 0 rotates, and on the lower end of this hollow spindle P is secured a sprocket-wheel 19, around which. sprocketwheel a chain 19 passes, the ends of this chain passing around guide-pulleys p and are then secured to the opposite ends of a quadrant 17 This quadrant is secured to the steering-head V of the front wheel V, and as the before-mentioned wheel P is rotated to the right or left the steering-wheel V is caused to move likewise.

In Fig. i we show a device which is intended to prevent unnecessary strain being placed on the driving-chains, which consists of connecting the axle boxes or bearings formed on the supplemental shaft G and the drivingshaft D by a bar J, and the weight of the vehicle and its load are carried by this bar J by means of the springs jj and the bearing= IIO plate It will of course be easy to understand that when the weight of the vehicle and its load, through some sudden jar or shock, tends to force the supplemental shaft Gr downward the latter will move in an arc of a circle of which the driving-shaft is a center, and thus relieve the chains of all strain.

To obtain greater ease in start-ing our vehicle, we have applied an automatic starter,

(illustrated in detail in Figs. 6, 7, and 8 and shown partly in Fig. 1,) which is intended to have a stored power which when released is utilized to turn the drivingshaft of the engine and start the same in its operation. The description of this device may be given as follows: To the horizontal shaft C of the engine is secured a ratchet-wheel 3, with which engage pawls 4, secured to a cog-wheel or pinion 5, which meshes with the upper part of a double rack-bar 6. This double rack-bar is secured to a head 7, traveling on rods 88, and to this head 7 are secured expansion-springs 8, which are arranged to be compressed between the head 7 and a similar head 7, and when the springs are so compressed a catch 9, secured to a shaft 10, hereinafter described, engages with a hook 9 and holds the head 7 in position to retain the springs in their compressed state. The shaft 10 and its handle or lever 10 are placed in such a position as to be easily reached by the operator, and this lever is arranged so as to control the movement of the catch 9. Y'Vhen it is desired to start the vehicle, the wheel 0 is turned to admit a supply of gas and air, and the lever 10 is then moved in order that the engine may be started to pump, compress, and fire the charge. This movement of said lever 10 causes the catch 9 to disengage with the hook 9, when the compressed springs 8 cause the head 7 and its double rack to move outward, and as said rack moves it operates the pinion 5, which, through the pawls 4 and ratchetwheel 3, operates the horizontal shaft C of the engine and starts all the mechanism in motion to move the vehicle.

Of course it is always necessary to again compress the springs 8 if the automatic starter is to be again used, and the mechanism for accomplishing this consists of the following parts: A small pinion 11 is loosely journaled to the shaft O, which meshes with the lower part of the rack-bar 6, an d which pinion forms one half of a clutch, the other half of which is formed on a sliding collar 12, which rotates with said shaft G. This collar 12 is grooved, and in the groove is one end of a bell-crank lever 13, the other end of said lever projecting into the path of a rod 14, hereinafter described. This bell-crank lever 13 usually occupies the position shown in Fig. '7, and it has a second lever geared thereto, and a spring 16 is provided, whose ends are so connected to the ends of said levers 13 and 15 that as soon as said levers are moved slightly out of line with each other the ends of the spring will be on one side of the pivots of said levers, and the spring will therefore cause said levers to move as far as they are allowed or until the clutches on the pinion 11 and collar 12 lock. tion of holding said clutches looked as long as the said levers 13 and 15 are out of line with each other. By the time the stored power of these springs has been fully utilized to start the engine the latter has sufficient power to drive the vehicle, and the rotary motion of its driving-axle is used to automatically recompress the springs in order that they may be used for a future starting. This isaccomplished as follows: hen the double rack-bar was moved to the left in starting, as hereinbefore described, the rod 14E was moved with it, and when said rack-bar is moved to near the end of its movement the said rod 14 comes in contact with and slightly moves the bellcrank lever 13. The moment this lever is moved out of line with its companion lever 15 the spring 16 acts, as before described, to complete the movement of the lever 13, and the latter acting on the collar 12 causes the latter to engage with the clutch on the small pinion 11, and as said collar 12 moves with the driving-shaft O motion is transmitted to said pinion 11, which, being in engagement with the lower half of the rack-bar 6, causes the latter to move to the right, the pawls 4 on the pinion 5 slipping over the teeth on the ratchet-wheel 3 as said rack moves backward or toward the right. The rack-bar is thus moved to its normal position, and when it reaches almost the end of the movement its end 7 strikes the bell-crank lever 13 and moves it in line with its companion lever 15, at the same time disengaging the clutch by moving the collar 12 away from the pinion 11, this action allowing the driving-shaft to freely rotate in said pinion, and during the movement of these parts the hook 9 has slipped past the catch 9 and is engaged thereby to prevent the springs from moving the rack-bar toward the left again until the same has been again released by the movement of the handle or lever 10 and its catch 9. I

From the above it follows that the starter is automatically reset, or rather reset by the action of the drh ing-shaft, immediately after the starter has expended its force and the engine begins work on its own accord.

From the above and the accompanying drawings it will be seen that we have produced a motor-vehicle which from the simplicity of the mechanism for starting, stopping, &c., can be managed without special skill or learning and that our vehicle is one which has great advantages accruing from the use of the variable-speed gearing, especially in the quick way in which it answers any change of the operating-wheel, and it will also be found very rapid in reversing, as the engine itself continues in its motion as though nothing had happened. Then by the use of our automatic starter we provide a vehicle which is practically a self-starting one, and thereby The spring also serves the func-.

are enabled to place all the operating parts in a complete housing, whereby they will be unaffected by bad weather, &c.

It is obvious that in lieu of the valve 2 for controlling the supply of gas and air to the gas-engine a controller may be used to feed current to an electrical motor, and the shaft g would then be used to operate this controller in a similar manner to that in which the valve 2 is operated; and in the following claims we intend to cover such and all other fair equivalents of the devices shown, unless said claim-s are specifically limited thereto.
