on NEW YORK, n. Y., A oonroRALIoN' or new YORK POWER TRANSMITTING MECHANISM Application filed March 3, 1930. Serial No. 432,734.

This invention relatesto improvements in mechanical movements and more particularly to power transmitting mechanism, and the particular object thereof is the provision of 1 an .efiicient means of transmitting power to a driven shaft, whereby the shaft may be driven in either direction without requiring the 'medium of a clutch or other similar device. All gears are dispensed with, and the control of the direction of rotation of the driven shaft is accurate and complete in each direction.

A further obj ect of this invention is the provision of means for transmitting power to the Wheels of a self-propelled vehicle without utilizing a differential.

A further object of this invention is the provision of means for lockingthe deviceand preventing rotation of the shaft when the parts are in an intermediate position.

Further objects of this invention include improvements in details of constructionand arrangement, whereby an efficient and simple mechanism of this character is provided.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, this invention consists in the construction, combination, and arrangement of parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawing forming a part hereof,-and which shows merely for the purpose of illustrative disclosure, a preferred embodiment of my invention, it being expressly understood, however, that various changes may be made in practice within the scope of the claims without digressing from my inventive idea.

Referring now to thedrawing, the numeral 1 designates a support in which the driven shaft 2 is rotatablymounted. A cylindrical rotary member or rotor 3jis keyed, or otherwise secured, to the driven shaft 1, the rotary member or rotor being'provided on its circumference with a plurality of spaced notches or cut-away parts 4: extending the full width of the rotor 3. Each notch or cut-away portion% is formed with a fiat bottom portion perpendicular-to a diameter of the rotor, and with the sides of the notch perpendicular to thefflat bottom portion.

If the parts are reversed it is to be noted that the notches 4 will be accordingly changed and may or may not be provided onthe pcriphery of the rotor. They are'symmetrical- I 1y arranged, however.

Mounted within each notch or cut-away portion 4 is a pair of-cylindrical rollers 5. It is to be expressly understood, however, that elements other than rollers may be employed, such as ball bearings, for instance. These rollers 5 have a diameter smaller than the maximum depth of the notches or cutaway portions. Spaced bands or rings 6 and 7 are slightly larger in diameter than the rotor .3, and form housing means for rollers 5. These rings (Sand 7 are loosely mounted on the rotor 3, and co-operate with rollers 5 to cause the'rollers to become wedged be! tween the rings and'the rotor and cause rotation of the shafts. By having rollers 5 of M,

smaller diameter than the" depth of the notches, it is possible to hold the rollers out of wedging contact with the rings 6 and '7 whenever it is desired. Lug 8 provided on the top of ring 6, and lug 9,:provided on the bottom of ring 7 are adapted for attach- ,ment to links 10 and 11, which links, in turn, are pivoted to a reciprocating member 12. Other means for actuating the rings Band 7 may be used. It is to be ekpresslyjunder- 1 a tures l8. lihe position given to the side plates 15 and 16 by this movement, places the spindles 20 so that the rollers 5 are free to drop downward on theleft side of the rotor to be wedged between the rotor 3 and rings 6 and 7, and the rotation of the rotor and shaft must follow in the direction indicated in Figure 1. It is to be noted that the rollers 5 on the ri ht side of the rotor are held up out of wedging relation between the rings 6 and 7 and the rotor 3.

In Figure 4 pins or rods 19 are shown intermediate the ends of openings 17 and apertures 18. The pins or rods 19 have been moved to this position by the interengaging of one of the rods 19 shown at the extreme right in Figure 1 with the eccentric grooves 33 of the locking arms 23 and 2t. Side plates 15 and 16 have also been turned a certain angle, and hence spindles 20 have been moved so that a wedging action between rings 6 and 7 and rotor 3 is obtained by positioning rollers 5 between the rotor 3 and the rings 6 and 7 on the left and right sides of the rotor. In this position, the device is locked and no movement is obtained.

In Figure 5 pins or rods 19 have been moved to the outer ends of openings 17 and apertures 18 and side plates 15 and 16 have been given an additional movement. Spindles 20, due to their connection with said plates 15 and 16 by means of openings 21 and 22, have been placed in a position to allow rollers 5 on the right side of the rotor to drop down and be wedged between rotor 3 and rings 6 and 7 so as to cause rotation of the rotor and driven shaft in a direction opposite to that shown in Figure 1. It is to be noted that the rollers 5 on the left side of the rotor are held up out of wedging contact, and that the position of the parts shown in Figure 1 is exactly opposite to that shown in Figure 5, and rotation of the driven shaft is obtained in the opposite direction.

When the device is used to transmit power in a self-propelled vehicle, no differential is required. A split axle isused and when one part of theaxle moves faster than the other, as when the vehicle is turning a corner, a running-ahead is permitted by the vehicle.

' The fact that the device allows the axle to run-ahead of the engine speed, gives the further advantage that whatever momentum the car may gain will be added to the engine speed, with the result that the car speed may be greater than the engine speed. In the cars now in use, with the engine in gear, the car cannot travel faster than the engine, and the momentum of the car is, therefore, lost.

It will be apparent that-I have provided a relatively simple device which will function to transmit power and rotate a shaft in either direction without using a clutch or similar device, and which can be used to propel 2. ve-
