POWER TRANSMITTING APPARATUS.

APPLIUATION FILED DEC 19.1905. 973,865, Patented Oct. 18,1910.

by heavy channel-members 19 held in place as by suitable brackets 20 and 21, and upon these cross-members is mounted an engine bed 22 and engine 23, preferably of the internal combustion type. Crank-shaft 24 of the engine is preferably provided with a sprocket-wheel 25 connected as by sprocketchain 26 with a similar wheel 27 upon the axle 11, this form of transmitting mecha nism being found peculiarly adapted for use in the relation shown, although other connections may be used and many of the advantageous features of my invention retained.

As shown in Fig. 1 of the drawings, the engine 23 Pprojects within the body of the car throng a suitable opening in thefloorframe thereof and the cylinders 28, with the controlling mechanism 29 mounted thereon, are thus brought within convenient reach of the engineer without sacrificing efliciency in the matter of the location of the crankshaft, the opening in the floor frame being, as clearly shown in the drawings, sufiiciently large to permit any desired relative movement ofthe engine with respect to the carbody. It may here be noted that the term controlling mechanism, as used herein with relation to the parts diagrammatically represented at 29, is intended to cover any device or devices by which the action of an portion of the engine is modified. Upon an e 11 is loosel mounted a sleeve 30 upon which is loosefy journaled the sprocketwheel 27 having secured thereto what may be termed a carrier 31 extending in a plane transverse to the axle as shown in ig. 3. Carrier 31 is provided with an inwardly directed flange 32 adapted to be gripped or clamped by the clutch-members 33 and 34 disposed u on each side thereof. Clutch-member 33 is heyed to the sleeve 30 i and is rovided with bolts 35 passing loosely 'throug the clutch-member 34 and having held upon their outer ends as by lock-nuts 36 the recessed collars 37. Fitting within these collars and taking against recesses 38 in the clutch-member 3 1 are actuating levers 39, the outer end portions 40 of which are, in general, of the elliptical form shown and the inner ends of which are secured in any desired manner to a sleeve 4]. loosely mounted on the axle. It will thus be seen that u on the sleeve 41 being reciprocated u on the axle, the levers 39 which lie in a p ane substantially parallel to that of the carrier 31 are given aswinging movement, resulting in the elliptical ends 10 thereof moving apart, or permitting to draw toether, the collars 37 and the opposite surace of the clutch-member 34. This move-,

ment, assuming the levers to be thrown in such direction as to bring the major axis of their elli tical ends niore nearly into alinemeet wit the pelts 35,'will cause the clutchmember to be thrown toward the flange 32 and the clutcl'i-member to be drawn outwardly toward the same part by means of the bolts, thus clamping this flange and completing the power-transniitting means from the sprocket-w]reel 27 to the sleeve 30. Upon the actuating lovers 39 being thrown by sleeve 41 intthe opposite direction, however, the outward pressure upon the collars 37 is relieved and lost motion bci 'g taken up as by springs iiifthe clutch-mcmbers 33 and M are forced apart, releasing the flange 32. The throwing of sleeve 41 is preferably accomplished by means of a loose band 43 fitted within a groove therein and provided with trunnions 44 lying within slots inthe end of a forked lever 45, pivoted as at 4:6 to a rigid frame 47 loosely mounted upon the sleeve 30 at 48 and upon the axle 11 at 49.

Lover is provided with an extension 50,

projecting up into the car and may, if de sired, be actuated thereby and held in position as by a locking segment 51, although in the preferred use of my inventionI mount a cylinder 52 upon the frame 47 and, by proper regulation of the pressure within the respective ends thereof, control through the piston-rod 53 the position of the lever. It will be seen that by the disposition of the parts as above extends, broadly speaking, in a plane transverse of the axle, and it is to be understood that expressions defining this disposition of the friction clutch are intended to be broadly construed as covering a general disposition of the parts in or near such a plane.

Fixed upon sleeve 30 upon the opposite side of sprocket-wheel 27 from the clutch mechanism above described is a gear 54 meshing with the gear 55 upon a counter-shaft 56 journaled within an extending portion 57 of the frame 47. -This extension is resiliently mounted upon an end bar 58 of the truck frame, as by means of the depending rods 5.) passing thercthrough, and the springs 60 and (31 disposed upon these rods. Mounted upon shaft 56 is a second gear 69. meshing with a, gear 3 loosely mounted upon the axle 11 and provided with a clutch-member (S 1 oppositely disposed to a similar part set forth, the friction clutch upon the first-mentioned gear 54. Keyed '67 loosely clamped about the some and pro- 11$ use of the several feacures thereof is sub friction-clutch is then thrown in, either by changed by means of the positive clutch,

clutch, but: is preferably iu'complishml by vided withlrunnions 68 taking into sloi'zs in the end of a forked-lover 69 pivoted it 70 to the-fmme Lever 69 is preferably provided with on extension 71 passing upwardly into the car-body and. permitting these parts to be thrown by hand, but in the preferred use of my invention ipi'ovicie iicylinder 72, mounted upon the frame 47, similar in construction and funcl ion to cyls' indcifiQ above described.

The operation of the obovedescribed em bodimcnt of my invention and method of stant-iallv as follows:

Assuming the clutch-member '66 to be in mid position and the flange 32' lo free from the enacting clutch-members ii ii be desired to start the car the engine is first put in motion and the cluiolrmen'ibcr thrown into engagement with either clutchmember or clutch-member (34, according high or low speed of driving desired, it being understood that by means of "the gearing upon sheila 56 the gears 54 and 63 are driven at diii erent rates of speed. The

power or by in manual actuation of the lever 45, and )ower is thus transmitted the engine through the sproclrebchain and friction-clutch to the sleeve 30 from which it passes through the gear 54 direct to member 66 and thence 'io axis 11 or through the oounter-shnft and gears 55 and 63, accordingto the position of the doublefaced clutch member, and thence through the latter part lo the axle 1i and wheels 13. hen it is desired to change the speed, the frictioncluich is first thrown out and the speed whereupon the friction-clutch is again thrown in, thus greatly reducing the strain upon the teeth of the positive clutch by res.- Son of the fact that the parts into engagemen with which ii thrown orceilher rein ti'vely stationary or their relative movement is that due to inonicntxun only. lho shock, moreover, is still further rcduccd by reason i of the resilient suspension of the ironic 4-7 whereby the counter-swift .36 will) the gears mounted ihercon may swing to n slight cent about the axle as'n center and thus further cushion the action of the parts. The vehicle may be brought to a standstill either by stopping the engine, throwing out the friction-clul'cli or throwing out thc'posil'ivc the second-mcut-ioncd moans. lly reason of the several ways in which the car may be brouoht to a standstill, however it will readily be seen that this may be ncconn plished with a. quickness and certainty which might be otherwise impracticable.

"It will. thus be seen that I have provided apparatus well adapted to accomplish the several objects of my invention and that this is of the simplest and most compile; con? sir-notion. The engine is resiliently mounted upon the arc es, i'hus avoiding the execs 'ive jar to the somewhat delicate mechanism thereof which would be occasioned by the absence of cushioning means between these ports. it is, nevertheless, so mounted with relation to the axle 2155 not only to reduce the lengih oi transmission to a minimumconsisient Wl'l'l'i cliicient action, but to be so disposed as to move only slightly with reference thereto. The cylinders of the engine, moreover, with their controlling mechanism project within the can so as to be instantly accessible in the engineer and yet do nol interfere with the mounting oi? the car-body in such manner as to have the easiest, riding qualities on account of the interposition of the sprii'igs l7 bciween lbc car-body and the illlClI-llll'lllllfi. The advantages of this ioni'nre are more clearly appnrcni in View of ihediliiculties which would arise in providen efficient transmission between the axle and the car-body ii the latter were inounlcd with suilicicnt resiliency to have the desired riding qualities and the engine were positioned within the car. The l'rni'isinitling mechanism mounted upon the axle, moreover, is so compactly disposed as readily to be positioned upon :1 single driving axle and yet is of the most eiiiciem'i character. On account of the controlling menus projectingfrom the transmission upon the axle into the car, will be seen that these parts are. not only within convenient rcnclrof i'ho. engineer, but- :u'c, together with the engine, so grouped shot all fcaiures of the powergcncrnling' and conlrolling ap 'mrnius is within instant reach oi. :1 single man. Another fcnturc to which attention should be called in this com'icction is the peculiar adaptability oi the entire nppnrniius described for use in connection with a motor car ndnpl'ed to travel upon rails and to be propelled all; a high rate of speed. The entire apparatus is thus of The simplest and most cilicicnii construction and, by reason. of these features. l'ogci'her will) its ease of control, is well adapted to meet the requirements oi practical use in the nbovc-noted relation.

As many chanlges could be made in the above coi'isliuction and many apparently widely diflcrent embodiments of my invenlion could be made without departing from the scope thereof, lintend lhiil: all matter conl'iiined in the above description or shown in the ncconn'innying drawings shall be interpreted. as illustrative and nol; in a limiting sense. I desire it also to be understood ilniithe language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetwcen.
