SPECIFICATION forming part of Letters P atent No. 350,017, dated September 28,1886

Application filed April 19, 1886. Selial No. 199,303. (No model.)

To all whom it may concern.-

Be it known that I, Nl-lw'rox RocEns, of .Terre Hante, in the county of Yigo and State ofIudiana, have'inventedcertain new and use 5 ful Improvements in Mechanism for Transmitting Power; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to devices for trans- I mitting the power derived from an engine to machinery, and has relation especially to devices for transmitting the power of a gas-engine to the axle of a street or other car, although it may be applied with good results to many other purposes.

It has for its especial object to furnish a dummy which shall carry a gas machine for generating a sufficient supply of gas by any well-known process of generating, a gas-en- 2 5 gine which shall receive its supply of gas from the aforesaid gas-machine, and suitable mechanism whereby the power of said gas-engine shall be effectually utilized and transmitted to the running-gear of the car; and with this object in view my invention consists in the improved construction, arrangement, and combination of parts hereinafter fully described, and afterward specifically pointed out in the claims hereto annexed.

55 In the accompanying drawings, Figure 1 is a top plan view of a car-truck provided with my improved power-transmitting mechanism, in which is also shown, by dotted lines, the position in which the gas-generating machine and the gasengine may be placed. Fig. 2 is a sectional view taken on the vertical plan a .1: of Fig. 1, looking in the direction of the arrow. Fig. 3 is a sectional view taken on the vertical plan 1/]/ of Fig. 1. Fig. 4 is a bottom plan view of a part of the devices shown in Fig. 1, showing especially the shifting or reversing mechanism; and Fig. 5 is a sectional viewtaken on the vertical plan z of Fig. 1, one end of said section, on the right,

being partly broken away. Fi 6 is a detail sectional view showing the dovetail block K,

having groove k, and the blocks to which the bearings H" H are seen red, fitting in said rooves.

Like letters of reference mark the same parts wherever they occur in the several fig ures of the drawings.

Referring to the drawings by letters of ref erence, A A are the end frame pieces or sills of the truck of a car, a a the longitudinal beams (30 or sills, and a an inner longitudinal beam, stringer, or sill, all of which parts may be of any suitable timber, and of a size to be regulated by the weight to be borne by them, and the judgment of the car-builder.

B B are the axles, carrying wheels I) I) and b b, and mounted in suitable bearings, I3 B, suspended in this instance below the longitudinal beams a a by means of suitable bolts, b b. The axles B B extend beyond the wheels, and, after the manner of the drivingwheels of a locomotive, are provided on each end with cranks C, wrist-pins G, and parallel connecting-rods 0, whereby they are caused to rotate in unison with each other. 7 5

D is another shaft, mounted in suitable bearings, D, located on top of the stringers or sills u, a, and a. This shaft is provided with a crank, d, to receive the pitman d of a gas-engine, which maybe located in either the position shown by dotted lines at E or that similarly shown at E, which engine receives its gas-supply from a gasgenerator by means of suitable piping, (not shown,) which gasgenerator may be located in any suitable po- 8 5 sition, as shown by the dotted lines at F or F, preference being given to the opposite end of the car from that on which the engine is located, for the purpose of suitably distributing the weight and ballasting the ear. 9(

On the shaft D, I mount a double-bevclfriction-gear, G,whieh I prefer to make of paper, although this material may be varied, which engages with two bevel friction-gears, G, preferably made of metal,whieh are mounted upon 9 5 the ends of two shafts, H H, lying in a slightlyinclined position and at right angles to the shaft 1), and are mounted in suitable bearings,

H H, as hereinafter explained. On the opposite ends of these shafts H H are mounted Ioo bevel friction-gears I I, similar]y.. shaped and of the same material as the gears G.

On the axle B, I mount a central double-bevel friction-gear, I, and two single-bevel frictiongears, I I, also preferably made of paper, which, as will be set forth further on, engage with the bevel friction-gears I on shafts H. Each of these shafts H H is provided with a universal joint, 71, and a longitudinal slipjoint, h.

v In order to keep the gears G G properly in contact with the double gear G, and in order to cause the gears I I to engage the double gear 1 or the single gears I I, as desired, the bearings H H and H. H, in which both'ends of the shafts H H are mounted, must necessari] y all be ad j ustablelaterall y. Each of these bearings is therefore provided with a dovetail projection or rib, h, on its under side, which has a bearing in a suitable dovetail groove in a lateral] y-extendin g pedestal-block,that block on which the bearings H H are mounted being marked K and its dovetail groove is, and that in which the bearings H H are mounted is marked K and its groove it. Each of the dovetail projections h on the bearings H H is perforated to receive a rod, i,which passes through said perforations, extending far enough on either side to serve as abearing upon which spring 5 is coiled, and which bear, respectively, against the outer sides of the bearings H H and. nuts i and 'i, which are threaded upon the ends thereof, and serve to regulate the pressure of the spring against the bearings, a block, i,with a plain bore, being interposed between the nut t' and the spring, the other nut, '11, (on the right hand of Figf5,) ,being, as is also the block 1'', accurately shaped to fit and move in the dovetail groove kin block K. By screwing up the nut 1'' there isset-up and maintained a spring or yielding contact between the gears G and G G,which can be very readily regulated at will.

The bearings H H, as before stated, are provided with dovetail blocks to fit a groove, k, in block K, similar to the dovetail blocks shown in section in Figs. 3 and 5; but they are, however, moved by the following mechanism: L L are two bars having, similarly to the shafts H H,slip-joints h h, and which are connected at their ends by bearings Z l and Z l,

to the shaftD and axle B, respectively, so that said shaft and axle turn freely therein. These bars L L serve as supports for the dovetail bars K K. On K,I mount a pivot, m, having a disk, on, on its upper end and its lower end squared, said, disk m being provided with two wristpins, to which are pivoted the ends of connecting-rods m, their opposite ends being connected to the bearings H H by suitable pivots. the pivot m (see Fig. 4) is mounted a rod, 01, pivoted at its outer end to a connecting-rod, a, similarly pivoted at its oppositeend to the arm a of the elbow-leverpivoted at n to the under side of bar L. The other arm, N, of this elbow-lever is pivoted toa rod, N, which On the lower square end of has at its opposite end a fork, o, in which is pivoted the lower end of a hand-lever, 0, said hand-lever being pivoted at o to a block on the bar L. Its upper end is provided with a handle, I and spring-pawl p, which pawl, at its lower end, engages the teeth of a segmentrack, 12, secured to any stationary parts of the machinery. By means of this hand-lever and its connections the bearings H H are simultaueously moved inward and outward toward or from each other, carrying the gears I I with them, and bringing said gears alternately into contact with either the double gear I or the gears I, accordingly as it may be desired to cause the car to run forward or back ward. This adjustment laterally of these ends of shafts H while the opposite ends remain stationary would be impossible but for the provislon of the universal joints h in theshafts H H; hence this provision.

As it will be necessary to mount the truck on springs which are in the axle-bearing boxes, but which I consider it unnecessary to show, as the car moves along the track there will be a vertical movement of the shaft D with relation to the car-axle B. Every motion of this kind tends to lengthen and again shorten the distance between said axle and the shaft. To accommodate this motion is the purpose of the slip-joints in the shafts H H and the bars L L, and without such or some equivalent provision the whole device would be inoperative and liable to be broken at the first attempt to use it. 7 Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is 1. In combination with the frame of a cartruck, an axle mounted thereon and having the friction-gears I I, the two shafts at right angles to the axle and carrying friction-gears I and G, said shafts being adjustable to bring the gears G nearer to or farther from each other, "and having universal joints h, and the shaft D, mounted in the frame and'provided witlrfrictio'n-gear G, as set forth.

2. In combination, the shaft D, having friction-gear G, the shafts H, having gears Gand I, sliia joints h, and universal joints h, and being adjusted laterally, as set forth, and the axleB, having gears '1 -I, and mounted in spring-bearings, as set fort.
