Auplicaticn filed December 1, 1904. Serial No. 235,103.

To an whom, it may concern.-

Be it known that I, CALVIN N. PAYNE, a citizen of the United States, residing at Titusville, in the county of Crawford and State of Pennsylvania, have invented new and useful Improvements in Speed Devices, of which the following is a specification.

This invention. relates to speed devices; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.

The invention is particularly adapted to speed-changin devices used with automobiles and as shown is designed particularly for this use.

Among the important features of the invention are devices through which various speeds may-be brought into action by. the continuous movement of the controlling mechanism in one direction. In other words, it is not necessary to bring the controlling mechanism to a neutral point to arrange the mechanism for the various speeds. The mechanism for each speed may be coupled u or released by the movement of the contro ling mechanism either to the next higher speed or next lower speed, and the movement of the controlling mechanism in either direction releases the mechanism just previously in action.

he other features of the invention will a pear from the following description of $1 1 6 claims.

The invention is panyin drawings, as follows: a side c evation of the device; Fig. 2, a View from the opposite side of the device; Fi 3, a section on the line 3 3 in Figs. 1 and. 2; Fig. 4, a section on the line 4 4 in Fig. 3, a part being broken away and in section to better show 5, a section on the line 5 5 in Fig. 3 Fi 6, a detail of the controlling mechanism; ig. 7, a section of said mechanism on the line 7 7 in Fig. 8; Fig. 8, a section on the line 8 8 in Fig. 6.

Alnarks thedrive-shaft, and B thedriven shaft. The driven shafthas the sleeved end B, whichpver'laps the driving-shaft A. The shaft'A ismounted in the bearing n supported'on th'epost N, baseNof the case. shaft A is carried in the sleeve end B", and

the sleeve B is carried by the bearing n ythe bearing n being supported by the post N illustrated in the accent Figure 1 shows extending from the The other end ofithe extending from the base N. The shaft B is also carried by the hearing it, supported by the post N this post also extending from the base N.

The drive-sleeve O is j ournaled on the 6c drive-shaft A. It is provided with the ballopenings 0, in which are arranged the clutchballs 0. The shaft A is provided with clutch-slots a, into which the balls 0 ma be forced for locking the sleeve C with the s iaft 6 The mechanism for accomplishin this comprises the strap I, caln and lip 1 the lip i being so formed as to prevent the move ment of the balls out of the openin s 6, but to permit a sufficient movement of t 1e balls to clear the shaft A, so as to release the clutch. The strap 1 is provided with a circumferential groove 1', in which the pins i are arranged. These pins are carried by the rock-arms I. The rock-arms I are carried by the shaft I 7 5 (See Fig. 5.) The shaft I is carried by the osts N extending from the base N. Arockever I extends from the end of the shaft, and the pin 1 of this rock-lever extends into a cam-slotP,arranged in thecam-platcP. The cam-plate P ismounted on the face of'the gear 0. This gear is carried by the bearing 12, and the bearing n is supported by the post N, ex-' tending from the base N. A rack O is slidingly mounted in the uprights N extending from said base. The shank O of this rack is connected to the cross-head J. The crosshcad J issecured 'to the operating-lever K. When the lever K is at the neutral oint, the pin I is at the point p in the camot. (See 0 Fig. 1.) As this lever is moved forward, the rack olperatin upon the ear 0 moves the cam-p ate an. the cam-s ot, so as to bring the pin 1 into the part 1) of the cam-slot. This compels a movement of the rock-lever I 5 and a consequent movement of the strap I, so as to pressthe balls through the action on the cam i and set the clutch.

A series of gears D, D, D, and D are fixed on the drive-sleeve O. Areverse-gear D is [00 also fixed on this sleeve and meshes the intermediate gear D A transmission-shaft F is mounted in the bearing n n, sup orted by the posts N 3 N extending from t 1% plate N. This shaft is hollow and-has mounted upon it the gears E, E, E ,and E meshing,respectively; the gears D, D, Dhand D It has a'lsothe reverse-gear E, the shing the intermediate gear D, it being driven by the "gear DI: The 1 I0 gears E, E, E, E, and E are provided with the clutch-slots e, e, c c and 6, respectively, The ball-openings f, f,f ,f", awlf" are cut through the hollow shaft 11 in the paths of the slots 6, c. (2*, e, and a", respectively, and these openings are provided with the clutch-balls f f f, and f", respectively. When these clutch-balls are forced out into the clutchslots they lock the gear into which they are forced with the transmissiornshaft. When, however, the balls. are allowed to re,- cede in the ball-openings out of the clutch slots in the gears, the gears are free to turn on the shaft, the gears being loose thereon. In the operation of the device, therefore, only the gear giving a desired speed is locked with the transmission-shaft. All the other gears, while they remain in mesh, turn freely on said shaft.

A controlling device is arranged in the hollow shaft F and is adapted to force the balls into the clutch-slots. it comprises the rod J. This is secured to the cross-head J by means of the nut The rod J has the longitudinal groove j. This groove is of sufiicient depth to permit the balls in register with the groove to move through the ball-openings a sufficient distance to bring them out of the path of the gears, or, in other words, to release the cars from the shaft. The rod J is locked against axial movement by the key j which is arranged in the inner part of the shaft and projects into the grooves f in the rod, so that the groove is at all times inregister circunn ferentially with the balls. Aball-actuating device 3' is journaled on the pin j, extending from the end of the rod J. This ball-actuat ing device has the groove i which corres )onds to the groove when. line therewith. tuating device j is beveled so that as the rod J, and with it the ball-actuating device, is moved through the shaft this surface j" engages the balls and forces them up through the openings in the clutch-slots to set the clutch. Ordinarily the device would be started at the neutral point and would first pick up the low-speed gear E and then the gears of the higher speed-gears E, E and E successively. The ballactuating device. is not of sufficient length to hold more than one set of balls in engagement at one time, and as it passes from under the balls they drop into the groove j, thus releasing the clutch from.

the gear just previouslylocked with the transmission-shaft. It may also be moved from the neutral point to the reverse gear E. Here the opposite end of the ball-actuating device engages the ball but it is so shaped as to effect this result. It may happen in the o eration of an automobile and of other ma ciiinery to which this may be a plied that the machine is stopped with the c utch set in the high gear. It is desirable to be able to brought into. The front end of the ball-ac-,

bring the controlling mechanism to the neutral point and to release the clutch from the high gear before starting the machine. therefore mount the ball-actuating device rotatively and provide it with. the grooves j and cam-surfaces j". The cam-surfaces contacting the balls which are held to the inner position by the inner surfaces of the gears turn the ball-actuating device on the pin j, so as to bring the groove j into register with the groove j, and thus permit the passage of the ball-actuating device past the balls.

Any convenient mechanism may be used for normally holding the actuating device in osition to force the balls into clutch relation. l have, however, arranged the following mechanism: The front end. of the ball-actuating device is provided with the cam j", which engages. a cam j on a camblock The cam-block is mounted on the pin j, but is locked against rotative movement by the pin which extends into the cam-block and slidingly into the o enings j in the end of the extension J Springs 1 are'mounted in the openings j so as to press against the pins j. As the ball-actuating device j is turned through the action of the cam-surfaces. j on. F acting against the cam-block forces the cam-block against the spring. As soon as the ball-actuating device passes by the balls the springs acting on the block 7' through the action ofthe cams j and 7 force the hallactuating device back to its normal position, It will be noted that the ball-actuating device may be moved immediately to position to throw any of the transmission-gears into enga enient even though the ball and socket,

of this gear is not for the moment in register, and when this hap )ens the ball-actuating device will bev turned against the tension of: the spring. so that when the ball-socket and balls opening come into register the ball-actuating device acting under the influence of the spring turnsand the slanting edges of the sleeve force the balls into engagement.

The transmission-shaft has fixed on its end a gear G, which meshes with the gear H This gear H has a sleeve-like hub 71, in which.

are ball-openings h. Balls 71 are arranged in these ball'openin s. The shaft B is provided with the clutc -slots b, into which the balls are forced to lock the shaft B with the sleeve 71. A strap ii is mounted on the sleeve. It has the cam-surface Z arranged to force the balls into the clutch-slots b with an axial movement of the strap and the lips Z for preventing the escape of the ballsfrom the opening. The strapL is provided with the circumferential groove 1, in which are These pins are secured These rock-arms are and this shaft is N in the plate arranged the pins 1. in the rock-arms L. mounted. on a shaft L mounted in the projections N. A link M engages the pins Z and Z and thus connects the straps I and L. A spring ll is tensioned against a projection Z and a shoulder Z on a pin L The end of the pin L is secured to one of the pins Z, and the spring is tcnsioned so as to force the strap forward to set the clutch through the action of the balls h. The link M where it engages the pin 11" has the slot m, which permits some play. When, therefore, the lever K is operated so as to force the strap I forward and set the clutch with the ball it also moves the pin 11 in the slot 71 and permits the spring L" to force the strap Ii forward. to set the clutch with the balls hf. If the link- M were positively connected to the strap, or, in other words, if the strap were not provided with the slot m the balls h which are then in the stationary driven shaft B, may be. in such position as to revent the immediate forward movement 0 the strap. It becomes necessary, therefore, to )rovnle mechanism whereby the clutch witi the driving-shaft may be set and the setting of the clutch with the driven shaft follows as soon as slot 6 is brought under one of the ball-o )enings h. f e variety It is desirable in order to add tot of speeds that may be attained to be able to connect the driving and driven shafts directly. I have arranged a mechanism whereby this may be accomplished through the action of the same controlling-lever K by moving continuously that lever in the direction it has been moved to bring into action the higher speeds. The driving-shaft. A is provided with the clutch-slots a. These are in the path of the ball-openings b in the extension B. The balls openings 6 and are in the path of the camsurfaces [J on the strap I. The lips 1) prevent the escape of the balls from the opening, but are of such size as to permit of the outward movement of the balls so as to disengage them from the driving-shaft. When the lever K has been moved forward so as to bring the in I at the end of the part 1) of the slot the ball-actuating device 1" has passed beyond the balls f, or beyondthe highest-speed gear. A further movement of the lever moves the rock-arm. I, and with it the strap I and L, so as to release the clutches formed by the balls 0 and k2. A further movement of the lever through the. action of the part p of the cam-slot moves the arm I, so as to bring the strap 1 to a position to force the balls 1) into engagement of the clutch-slots a. This looks the shaft A directly with the extension B, and consequently with the driven shaft. At the same time t e transmission-gear has been thrown out both by the clutch formed with the openings h and the clutch formed with the openings c. As the lever is returned to the neutral point the clutch between the driving are arranged in the 'and driven shaft is first released. Then the clutch formed by the balls h and c is thrown in, and the high-speed gear is picked up and the lower-speed gears in succession. The only purpose of providing the neutral point is to save the wearon the gears. Simply ringing the ball-actuating device 7'- to a position between the gears E and E would stop the driving action of the device; but the movement of the lever K not only brings the ball- .actuating device j to that position, but also .brings the part p of the cam-slot into action to throw on t the clutch between the drivingsleeve C and the driving-shaft, so that the only wear is between the driving-sleeve and driving-shaft. If it is desired to hax e a reverse movement of the device, the lever is .thrown still further in the backward direction, brin ing into action the part p of the cam-slot which throws the lever I", so as to throw in the clutch between the drive shaft and driving-sleeve'C, and this movement of the lever also brings the ball-actuating device 7' under the ball e, so as to lock the reverse-gear with the transmission-shaft.
