DRIVING AND REVERSING CLUTCH.

T0 all 'whom t may concern:

` Be it known that I, Gnonen HAzEnroN, citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and usefulv Improvement in Driving and Reversing Clutches, and declare the following to bea full, clear, and exact description of the same, such as will enable others skilled'inl 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 specification.

My invention relates to an improvement in a driving and reversing clutch, designed more especially for use in connection with motor boats, though it may beV employed in conjunction with hoisting apparatus, or in other installations lwhere ldevices. of this character are required.

One object of the inventionV is to provide an eicient'driving and'reversing clutch in which the driving shaft while 'rotating in one direction may be coupled with the'prepeller shaft of a boat (for example) to drive the latter forward, orto reversefthe same as maybe required.A 'n `v 'A I In putting the invention into enect, a double annular cone is fitted 1tothe driven or propeller shaft, which may be actuated in va forward direction by a slidabl'ein'ember keyed to the driving shaft engaging one 'of the annular cone'portion's, or in a reverse direct-ion through a plurality of intermediate rolls forced into impinging relation with the other annular cone lportions bythe manual shifting of the slidable member in the vreverse direction along the ldriving shaft.

Another feature of the invention consists in providing an adjustable locking 4device Y for the manually 'operated lever employed to shift the slidable member keyed to the engine shaft.

Other advantages and improvements wlll hereafter appear. 'v

AIn the ldrawings accompanying this speciication: Figure 1 is a yhorizontal sectional `view throughthe clutchmechanism, 4taken on the parting line of the inclosing' case,

showing the mechanism coupled to provide a forward movement lof the propeller blades (not shown); V Fig. 2 is a similar View showing the rolls of the yclutch mechanism forced into rolling driving contact with'the double cone carried by the propeller shaft,'thereby reversing the 'rotation' .the Propeller SpecificationV of Letters Patent.

Fig. 5 is a side elevation of the device. Fig. l

6 is a crossse'ctional View on lline 6-6 of Fig. 1.y Fig. 7 is a cross-sectional view on line 7 7 of Fig. 2. Fig. 8 is a fragmentary View of the lever for manually operating the clutch mechanism,` indicating the same locked a neutral position. Fig. 9 is a like fragmentary elevation ofthe lever and locking mechanism as; viewed from the opposite side, indicating the lever shifted and locked in 'its adjusted position.

Referring now to the letters of reference placed upon the drawings: A, indicates a driving shaft journaled at its forwardl end in a 'suitable bearing in the inclos'ing case B, divided horizontally and bolted together on a Iipe'with the'driving shaft.

' C', is a'propeller shaft having a socket fitted with a bushing 0,'to receive the end ofthe driving shaft, which is reduced in diameter atone end that it may'enter the endbf the p 'opeller shaft, as indicated in Fig/1 ofthe drawings. d i

C', denotes a collar pinned to the propeller shaft, inturnbolted to va similar collar carried by the shaft of the propeller blades (not shown). i A

"c", isa' thrust bearing between the shoulder a., ofthe driving shaft, and the end of the propeller shaft,"'andl 0?; is a similar thrust bearing between the collar C, and the projec'ting hub ofthe bearing, inthe inclosing case B, supporting the propeller shaft.

` C2,is an annular cone'tapering toward Ythe propeller shaft C, having a screw-threaded engagement with the latter, its enlargedend being formed with a projecting flange C'to which is boltedthe flange Cb, of an annular cone C3, tapering toward the driving shaft'A. D, is an annular slidable shaft'sleeved on the driving shaft A, provided with a slot at'qZ, forthe passage of a key A, carried yby the" shaft A, the rslot being of suiicient llength to admit of a longitudinal movement of theV annular shaft along the driving shaftj-thekey however causing the shafts to rotate as a unit.

@indicates a cone housed within the annular cone Cha'ving a projecting'taperin'g hubA E', screwed upon the end of the slidable shaft D, toreciprocate therewith.

' denotes anadjustable annular frame or cage sleeved over the tapering hub E', proi vided with a projecting collar F, extending into a supporting ring G. VrI`he ring Gr, is provided with ears g, through which project bolts g, for securing the ring to the lugs b, of the case B.

G, is a set screw carried by the ringil to secure the collar F, to the latter, upon releasing which, the frame F, may be adjusted to take up wear.

H, ,designates a plurality of rolls mounted on the shafts H, in turn loosely pinned to the annular frame F, the shafts being free to move along the pins l1., in the slotted openings f, of the frame F, to provide for a slight radial adjustment of the rolls, whereby they may be forced into driving rolling contact with the annular cone G3.

7L, are springs carried by the pins L, adapted to force the rolls I-I, inwardly when released from driving engagement with the cone C3.

I, indicates a rocking, shifting lever, having trunnions I, journaled in a suitable bearing carried by the inclosing case B. Within the case B, the lever is forked, its slotted tines I2, receiving the projecting lugs J', of a collar J, mounted upon the annular sliding shaft D, between the ball bearings K.

L, is a push rod supported in the lever I, having a projecting end L.

M, denotes a pair of adjustable blocks fitted with bolts M', projecting through elongated slots a, in the quadrant-shaped frame N, secured to the inclosing case B.

mi, mi, are lugs eXtendin from the blocks M, M, with which the projecting end L, of the push rod engages to secure the lever following its manual adjustment.

L3, is a spring mounted upon the upper end of the push rod bearing against the enlarged ends L3, ofn the rod, and against a shoulder formed in the lever I, to receive the spring z--the purpose being to normally maintain the projecting end L, of the rod in engaging relation with the lugs of the adjustable blocks M, M.

L4, is a keeper attached to the lever to secure the push-rod against displacement.

O, designates a collar pinned to the driving shaft to secure the shaftv against lateral displacement. p

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

For purposes of description and to more clearly indicate the operation of the device, 1t is assumed to be employed in connection with a motor boat (not shown). When it is the desire of the operator to drive the boat forward, the lever I, is manually operated forcing the cone E, into impinging relation with the annular cone C2, (as indicated in Fig. l of the drawings) thereby rotating the latter in the same direction as that taken by the driving shaft A,-the lever being locked in its adjusted position by the projecting end L, of the push-rod L engaging the lug of the adjustable block M, as indicated in Fig. 9 of the drawings. bIt will now be assumed that it is the desire of the operator to shift the clutch to a neutral po- A sitionv; z'. c. 'the engine being permitted to run without operating the propeller blades. To accomplish this result, the operating lever I, is given a slight movement to the left suficient to release the cone E, from driving engagement with the annular cone C2, the lever being locked in its neutral, or released position by lodging the projecting end L', of the push-rod L, between the lugs m, m, of the adjustable blocks M, M,-as indicated in Fig. 8 of the drawings.

It will now be assumed that the operator desires to reverse the direction previously taken by the propelling blades. rlhis result is accomplished by a further movement of the operating lever I, to the left following the operation of the push-rod whereby it is released. This action causes the tapering hub E', of the cone E, lto move to the left suiiiciently to force outwardly the rolls H, into impinging contact with the inner face of the annular cone C3. The rolls contacting throughout their length with the tapering hub E', are rotated thereby in an opposite direction to that taken by the tapering hub and driving shaft A, while the annular cone C, driven by the rolls through contact with its inner face, is revolved in the same direction as that taken by the rolls, and therefore in an opposite direction to that of the driving shaft; the rotation of the driven shaft C, being thus reversed to that of the driving shaft. If desired the lever I, may be locked by the push-rod L, acting in conjunction with the adjustable blocks M, M, to secure the clutch mechanism in its reverse position in a similar manner to that previously explained relative to the forward and neutral positions. It will be obvious that while the driving shaft operates 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 Controlling lever.

Having thus described my invention, what I claim is: j

l. In a device of the character described, a supporting frame, a driving shaft journale therein, a driven shaft, a pair of annular cones tapering in opposite directions mounted upon the driven shaft and operating as a single unit therewith, an annular shaft slidable upon the driving shaft keyed to rotate therewith, a cone carried by the annular shaft having a projecting, tapering hub and adapted to be forced into driving relation with one of the annular cones of the driven shaft, a frame surrounding the tapering hub having radial slots to receive the shafts of a plurality of rolls, a plurality of rolls rotatable upon shafts projecting into the slots of the frame, transverse pins for supporting said Shafts in the slots of the frame, springs adapted to bear upon the shafts of the rolls to force them in- Wardly to the limit of their travel in the slots of said frame, and manually operated means for shifting said annular shaft, whereby the tapering hub of the cone earried by the annular'shaft is adapted to force said rolls outwardly and into impinging relation with the other annular cone.
