DRIVING AND REVERSING GEARING.

Application led February 3, 1913.

To all whom t may concern Be it known that I, HARVEY ELLIOTT, citizen of the United States, residing at Detroit, county of lNayne, State of Michigan, have invented a certain new and useful Improvement in Driving and Reversing Gearing, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specilication.

My invention relates to a gearless driving and reversing clutch which may be used to advantage in connection with motor boats, hoisting apparatus, or other like installations, as shown in the accompanying drawings and more particularly set forth in the following specification and claims.

The object of my invention is to produce an efficient and inexpensive driving and reversing clutch, dispensing entirely with the trains of gears usually employed in devices of this character-the construction being such that the driving shaft while rotating in one direction may be coupled with a propeller shaft (for example) in line therewith, to drive a boat forward or to reverse the same as required.

Other advantages and improvements will be hereinafter set forth and more particu larly pointed out in the claims.

in the drawings accompanying this speciication: Figure l is a horizontal sectional view through the clutch mechanism with parts in elevation taken on the parting line of the inclosing case and showing the mechanisni coupled to provide for a forward movement of the propeller blades (not shown). Fig. 2 is a cross-sectional view on line 2 2 of Fig. l. Fig. 3 is a side elevation of a detail adjacent to the shifting fork. Fig. 4l is a cross-sectional view on line 4 4 of Fig. 5. Fig. 5 is a horizontal sectional view of a detail with the several rolls of the clutch mechanism in rolling driving contact with the cone carried by the propeller shaft as in reversing the propeller blades.

Referring now to the letters of reference placed upon the drawings A indicates a driving shaft journaled at its lforward end in a suitable bearing in the inclosing case B, which is divided into two parts longitudinally, and ybolted together in line with the driving shaft. The rear end of the shaft A is preferably reduced in diameter and housed in a bushing o inserted in the propeller shaft C, as indicated in Fig. l of the drawings.

C denotes a collar keyed to the propeller shaft in turn bolted to a similar collar carried by the shaft of the propeller blades (not shown).

C2 is a disk preferably integral with the propeller shaft to which is bolted an annular cone C3.

c is a thrust bearing between the shoulder a of the driving shaft and the disk C2, and c2 is a similar thrust bearing between the collar C and the projecting hub Z) of the bearing formed in the inclosing case B to receive the propeller shaft C.

D indicates an annular shaft sleeved on the shaft A provided with a slot at d for the passage of a key A carried by the shaft A, the slot being of sufficient length to admit of a longitudinal movement of the annular shaft along the shaft A, with which it is caused to rotate by the key A.

E denotes a cone-shaped ring housed within the cone C3 and keyed as indicated at e to the annular shaft D.

E is a movable key supported in the wall of the ring E adapted to be thrust outward into a key-way e', provided in the cone C3, through the action of the spring E2.

F is a cone, of relatively dierent taper to the annular cone C3, sleeved on the annular shaft D, and provided with a key-way f to receive the projecting key A carried by the driving shaft, whereby the cone F is caused to rotate therewith while being adapted for longitudinal movement with respect to the shaft.

F is a projecting sleeve preferably integral with the cone F, formed with a flange F2 channeled to receive the friction rolls G carried by the shifting fork G. At F3 the end of the sleeve F is given a substantially cone-shaped formation with an annular recess f adapted to receive the fingers 7L of the dogs H. The dogs H are pivoted to the collar l which in turn is carried by lthe annular shaft D.

f2 is a port in the cone F through which oil may be delivered to the periphery of the annular shaft D upon which the cone F is designed to slide.

G2 indicates a transverse shaft journaled in the frame A to which the shifting fork is keyed.

G3 is a lever keyed to the shaft G2 for manually operating it.

J denotes a collar pinned to the driving shaft A provided with an inclined yflange against which the fingers lz of the dog H bear.

K is a helical spring sleeved on the driving shaft A, one end of which bears against the collar J, and the other against the end of the annular shaft D. v

L indicates a supporting ring provided with ears Z pierced for the passage of bolts Z by which the ring is secured to the projecting lugs b of the inclosing case B.

-M denotes an adjustable annular frame or cage sleeve over the cone F and provided with a projecting hub M extending into the ring L.

L is a set-screw carried by the ring L to secure the hub to the ring, upon releasing which the frame may be adjusted to take up wear.

N denotes a vlurality of rolls mounted on the shafts in turn keyed or pinned to the annular frame M,-the shafts being Vfree to move along the pins to provide for tacting surface throughout their length with both the inner face of the cone C3 and the outer face of the cone F, thereby insuring an equal or like speed transmission between the gradually increasing diameter of the cone and the rolls throughout their entire length. ny is a bushing on which the rolls rotate.

O is a casting bolted to the cone F and provided withan inclined slotted way O through which projects the spring E2 engaging the movable key E.

Having indicated the several parts by reference letters, the construction and operation of my device will be readily understood. Y

For purposes of description and to more clearly indicate the operation of the device, it is assumed to be employed in connection with a motor boat (not shown), though it is equally well adapted for other installations.

When it is the desire of the operator to drive the mot-or boat forward, the lever G3v Y is manually placed in the position indicated in solid lines in Fig. 1 of the drawings. TvVhen in this position, the fingers h' of the dogs H, rest in the depressiony f formed in the periphery of the cone-shaped portion F3 of the projecting sleeve F, the fingers L bearing upon the inclined flange of the coli lar J, thereby securing the sleeve against accidental longitudinal movement with respect to the driving shaft A. The movable key E carried by the cone-shaped ring E is forced outward and into locking relation with the annular cone C2 through the ac tion ofthe spring E2, placed under increasing tension through the rearward (or right hand). movement of the casting O bolted to the cone F when the lever G3 is moved to the position indicated z-it being obvious that the tension of the spring is increased due to its slid-ing up the inclined way formed in the casting. The cone-shaped ring E when brought into impinging relation with the innery face of the annular cone C3 will rotate the latter, causing the propeller blades to move with the drive shaft or in a forward direction.` Should the load, however, be sufficient to cause slipping between the ring E and the inner face of the cone C3, the movable key E will lock the cone ring E in a positive driving relation with the annular cone C3 immediately yupon the key E registering with the key-way e in the cone,- the spring E2 forcing the key to its seat.

It will now be assumed that it is the desire of the operator to throw the device into a neutrall position; z'. e., the engine being permitted to run without operating the propeller blades. To accomplish this result, the operating lever ,G3V is given a slight movement to the left which serves to unseat the lingers h of the dogs VH from the depression f in the cone-shaped portion F3, which action permits the spring K to force the sleeve to the right along the driving shaft A, carrying with it the coneshaped ring E and at the same time automatically releasing the movable key E from engagement with the annular cone C2,-it being obviousthat the spring E2 engaging the movable key, being acted upon by the inclined way in the casting O, will serve to withdraw the movable key from its locking engagement with the annular cone when the sleeve F is forced to the left due to the manual operation of the lever G3.

It will no-w be assumed that it is desired to reverse the direction previously taken by the propeller blades. This result is accomplished by a still further movement of the operating lever G3 to the left. This action causes the cone F to move to the left sufficiently to force outward the rolls N into impinging contact with the inner face of the annular cone G3. The rolls contacting as they do throughout theil` length with the cone F, are rotated thereby in an opposite direction to that taken by the cone F, and the driving shaft A,-at the same time driving the annular cone C3-by a rolling contact with its inner facein the same direction as that taken by the rolls and in an opposite direction to that taken by the driving shaft, thus reversing the movement of the propeller shaft C. 1t will therefore be obvious that while the driving shaft 0perates in one direction only, the propeller shaft may be actuated in either direction or remain at rest, as governed by the adjustment of the manually operated lever G3.

Attention is directed to the fact that when the lever G3 is again moved to the right,- to the position occupied when driving the boat forward,the cone-shaped portion F3 of the sleeve F will cause the dogs H to tilt due to the action of the lingers 7b bearing thereon while the fingers L, bearing upon the inclined'face of the collar J will cause the annular shaft D to move slightly to the left and against the action of the spring K, thereby bringing the cone-shaped ring E, carried by the annular shaft, into impinging relation with the annular cone C3. Upon shifting the lever G3 to the left to either a neutral or reverse position, the spring K will again become active forcing the annular shaft D to the right, thereby assisting in releasing the cone-shaped ring E from engagement with the annular cone C3.
