DRIVING MECHANISM.
SPECIFICATION formingpart Of Letters Patent No. 712,058, dated October 28, 1902. Application filed July 15, 1901. Serial No. 68,434. (No model.)
motor-cycles, or other vehicles; and our invention consists of a centrally-driven pinion gearing by means of carrier-wheels, as desired,with one of aseries of internally-toothed wheels, which latter may be gripped or locked, whereby the carrier-wheels will be caused to rotate the disk on which they are supported, which motion is by a suitable chain-wheel or other means transferred to the main axle of the vehicle, the reverse movement being obtained by locking the disks,and thereby causing one of the internally-toothed rings to be rotated, the chain-wheel being by a suitable clutch connected and disconnected to and from the rotatory parts as desired; and our invention further consists in means whereby the movement and locking in position of the centrally-driven pinion will also cause the brake-band or equivalent means to be operated.
We will, as an example, describe our invention when made as a three-speed gear having a single-speed reverse; but we do not wish to limit ourselves to any number of speeds.
In order that our invention may be readily understood, reference is made to the accompanying drawings, wherein like numerals of reference indicate corresponding parts throughout the several figures, and in which- Figure 1 is a side elevation, partly in section,'of our improved gear, the section being on line A B, Fig. 2. Fig. 2 is a sectional plan view of Fig. l, the driving-shaft and its pinion and one of the carrier-pins being, however, shown full. Fig. 3 is a side elevation of means for applying the band-brakes. Fig.
4.- is a sectional view on line C D, Fig. 2, of a part of one form of clutch. Fig. 5 is a perspective view of the-other part of the clutch;
and Fig. 6 is a side elevational view, on an enlarged scale,of one of the internally-toothed wheels and a set of carrier-wheels in gear therewith.
In carrying our invention into practice we mount a pinion 1 on the motor-driven shaft 2, said shaft having a keyway 3 cut in it in which a key or equivalent, with which the pinion 1 is provided, fits so as to permit the said pinion to slide a sufficient distance along said shaft without being able to be rotated thereon. On said shaft 2 we .mount four disks 1, 5, 6, and 7, three of which4, 6, and 7 --are each provided with, say, three carrierwheels 8, mounted on pins 9 and so situated that each set of carrier-wheels can gear with the central pinion if the latter be moved along the shaft 2. The disks 5, 6, and 7 have central apertures to permit the pinion 1 to slide from one end to thejother of our improved gear, and the whole four of the disks are connected together, so that they must move in unison, by cotters and pins 10 or equivalents, these being situated in the ring 13 being held in position by a suitable bearing 16 about as shown.
The action of our improved mechanism is as follows: The pinion 1, which is shown in the drawings adjusted to the quickest speed, gears with and rotates the carrier-wheels 8 on'the disk 7, which would result in rotating the toothed ring 13 but that this latter is by a suitable band-brake 17 or equivalent means held stationary, so that the disk 7, and com sequently also the sleeve 18, with which the disk 1 is formed or provided, is rotated,'the rotation being in the same direction as that of the pinion 1, but its speed depending upon the relative diameters of the pinion 1 and the toothed ring l3.- Similarly, if the pinion 1 be moved along theshaft 2 so "as to engage with the carrierwheels on the disk 6 the sleeve 18 will be rotated, but at a slower speed than before, inasmuch as the toothed ring 12 is of greater internal diameter than the toothed ring 13, the slowest speed being attained by engaging the pinion 1 with the carrier-wheels 8 on the disk 4, as the toothed ring 11 has the largest internal diameter.
For the purpose of transferring the rotary motion of the sleeve 18 to the axle of the motor-vehicle we employ a chain-wheel19, which by means of a chain (not shown) is in gear with a chain-wheel on said axle in any usual manner. The chain-wheel19 is adapted to rotate on the sleeve 18, butis prevented from moving laterally along it at one side by a shoulder on the sleeve 18 and at the other by a part 20 of the clutch. Said part 20 is fixedly attached to the sleeve 18 and is formed with, say, three circularly-disposed recesses 21 for gearing or connecting the chain-wheel 19 to the sleeve 18, into which recesses the correspondingly-slotted end of the other part 22 of the clutch may be entered. The part 22 is in the form of a tube which surrounds the sleeve 18, and its slotted end projects through corresponding grooves or slots in the chainwheel, so that said part 22 may be engaged with or disengaged from the recesses 21 by moving a handle 23 or in any other suitable manner, the arrangement being such that when the sleeve 18 is rotated in the manner hereinbefore described and the part 22 engaged with the recesses 21 the chain-wheel will be rotated in one direction. For the purpose of reversing the rotation of the chainwheel the sleeve 14 is rotated in the manner already described and the part 22 of the clutch is disengaged from the recesses 21 and moved a sufficient distance toward the sleeve 14 so that pins 24, with which its opposite end is provided, engage*with corresponding apertures in the boss of said sleeve.
For the purpose of moving the pinion 1 along the shaft2 and in order that the movement of the wheel to the desired gear will also put into operation the relative bandbrake,we provide a handle 26,fixedly attached to a shaft 27, capable of being slid transversely along in bearings 28 and rotated to a sufficient extent. On said shaft we loosely mount an arm 29, which is arranged so that it moves laterally with said shaft 27, and the opposite end of said arm is connected to a sleeve 30, With which the pinion 1 is provided, the arrangement being such that Whatever distance the handle 26 be moved the pinion will move an equal distance.
In order to lock the parts in their proper positions, as desired, we provide two side plates 31 and 32, the former having slots 33, 34, 35, and 36 and the latter a slot 37, so that if the handle 26 be engaged with the slot 33, as shown in the drawings, the pinion will be in engagement with the carrier-wheels of the disk 7. The handle 26 cannot,however, be moved laterally until it has been raised to a vertical position, as indicated in dotted lines in Fig. 3, after which it may be moved along between the plates 31 32 and entered into any one of the other slots, the slots 34 and 35 corresponding, respectively, to disks 6 and 4.
For the purpose of automatically applying the relative band-brake 17 we mount two cams 38 39 (formed, preferably, in one piece) on the shaft 27, the form and position of which cams are such that when the handle 26 is engaged with the slot 33 the cam 38 depresses the first brake-band 17, about as indicated in Figs. 2 and 3, and thereby causes said brake-band to grip the internally-toothed ring 13. If the handle be moved into engagement with either the slot 34 or 35, the cam 38 will in a similar manner cause the relative band-brake to grip in the one case the toothed ring 12 and in the other the toothed ring 11. If the handle be moved still farther and engaged with the slot 36, the pinion 1 will be moved clear of all the carrier-wheels into a recess 40 in the disk 4, so that when the vehicle is stationary the motor can remain in motion without any of the gear-wheels being uselessly rotated. The cam 38 in this event is also clear of all the brake-bands 17.
For the purpose of rotating the sleeve 14, which is necessary to reverse the motion, the pinion 1 must be engaged with the carrierwheels 8 on the disk 4 and the disks held stationary, as already described, and in order to accomplish this it is only necessary to engage the handle 26 with the slot 37 in the plate 32, when the cam 39 will depress the band-brake 17 of the disk 5.
