IMPROVEMENT IN HORSE-POWER.

T0 ALL WHOM IT MAY GONCERN:

Be it known that I, DANIEL J. TITTLE, ofthe city and county of Albany, State of New York, have invented an Improvement in Horse-Powers for Railroads, Svc., wherebycars can be'drawn ahead, or bhcked `up,or stopped, at the will of the driver in charge; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to tl'icaeeompanying drawings, forming a part of this specification, and to the letters of reference markedthercon, the same letters indicating like parts, in wlii'ch- Figure 1 represents a vertical view from above, with the upper portion of the endless-tread apron removed.

Figure 2 represents a longitudinal cross-section of invention.

Figure 3 represents a lateral cross-section, front of the centre of thcsame.

Figure 4 represents two pieces of the endless apron, viewed from their inner sides.

The nature of my invention consists f an endless-tread apron, furnished with two sets of cogs. One set ot the said cogs are placed at the ends of the tread-pieces, and'said tread-'pieces are furnished .with but two of these cogs, one :it each end. The other set of cogs are placed midway betweenthe ends of the tread-.pieces in a single row, and each piece is furnish'cd'with several such centre coge. The two outside-rows of coge work on the front and rear carrying-wheels. Theshaft 4of the frontA carrying-wheels is providedwith a gear-wheel, which works into another gear-wheel, fixed' to the axle of the drive-wheels.` The gear-wheel of 4the carryingwheels shaft isv fixed by a feather from turning, and can move in a lateral direction from the gear on the-drive. wheel axle, and by means of a suitable lever theyvmay be thrown out or=-in gear at pleasure. Y

The Vcentre row of ccgs`(on the tread-pieces) mesh in and work direct on the drive-wheelswhen thrown in gear by a. lever, which operates one or more rollers beneath the endless tread, and which press the said cogs into the drive-wheel gear. A pan 'is placed under the whole 'length ofthe endless tread, which catches the dung and urine of the animals working the machine. Suitable holding-clamps, provided with set-bolts, and mash-nuts, are placed at proper points, front and back, on the sides, by which the required inclination of the tread is held securely.

To enable others skilled in Vthe art to make and use my invention, I will proceedto describe it in reference tothe drawings, and letters ofreference marked thereon.

A A, gs`. 1, 2, 3, represent the supporting-timbers of machine, to which are attached the journal-boxes a a of the carrying-wheels shafts, `itigs. 1 and 3. To the said shafts b b are attached the carrying-wheels e c c c. These carrying-wheels have in:them, around their outer edges,vthe notches olli. v

The endless tread B, gs. 1 and 2, is constructed of many tread-pieces, ee, jointed together, as e e in fig. 4. The said tread-pieces'may be made wholly or in part of iron or wood, or both..- On the inner side of the treadpieces, next to the links f f, iin. 4, are placed the single cogs gg. These cogs` work in the notches d, andVV operate the carrying-wheels e c, iig. 2, moving them in the direction indicated by the arrows marked thereon.

Placeden the shaft b of the carrying-wheel c, figs. 1, 2, and 3, is the gear-wheclK, which is prevented from turning on the shaft by a feather. The said gear K can move in a lateraldire'ction, and be thrown in or out of g'ear with the second gear-wheel M, by means of the lever t', acted upon by a second lever, u, and draw bar o, igs.1 and 2.

The eogs 7L h 7i, on the tread-pieces e c, iig. 4, are placed near midway between the4 outer cogs g g, and may,

at wi1l,`operatc'in the cogs of the gear M, iig. 2, from the'lowel' side, and will turn the said gear-.wheel M in a direct'ioncontrary to that of gear-wheel K when it is in motion. The cogsh h are not to be made to .work in the cogs of the gear M only when the wheel K is vthrown out of gear from the 4wheel M, except when it is desirable to stop the machine.

Thefgear-wheel M is attached to the shaft plof the drive-whcel D, 'andpwill cause the said drive-wheel D tc revolve forward or backward, according as it is driven by the gear-wheel K, or by the' cogsV t t-of the endless tread- B, `figs. 1 and 2. 1

under side of the machine obliquely, as is indicated by the red dotted lines in fig.

To throw the eogsh 7L in work with the gear-wheel M, the rollers 1'. 1', placed under the endless treadAigs. 2 and 3, are thrown upward against the face of the said tread, by means of the lever S, onnected with the roller-holding bars t t bythe link w and ear 11g. 2; and when thrown in gear, the said tread is kept in centact wth'the said gear M by the lever S beingheld down by the handled -hook W', moved in direction of the red dotted lines in tig.. 2. The holding-rollers rm are placed in a suitable bar-frame, t, which traverses the '17 and is connected to the timbers A A by a joint hinge starting down therefrom on the opposite side from the lever S.

F -F F F is the usxial framework of a truck, to which are attached the usualcoupled wheels D D D D by proper axle-boxes. The shafts or axles of the said wheels pass through between the upper and lower sides of the endless tread, as is shown in figs. 1 and 2. And the tread-power is sustained .by the truck-timbers F F by means of the clamping holders a; 2:', iigs. 1 and 55,placed front and back on each side, and held secure by the bolts and their nuts y y. By means of the holding-clamps x fc', and the b'inding-bolt'and its nut y, the incline of the endless tread can be adjusted and securedi A pan, Z, is placed under the endless tread to catch the excrements that may fall from the animals, and is supported from the tread-'timbersA A, ormay be supported by the truck-timbers F F. i

The usual side-piece (not represented in the drawings) vmay be placed and attached yas is generally dene.

To operate this power, the animals are pla-ced on the tread B, whentheir weight and draughtwill give to the tread a movement in direction of the arrows, iig. 2. The tread carriedby they wheels c e, c c", which more .in the said direction, is also carried andrsupportedbetween the two ends by the'bearing rollers gig, let in and supported by the upper timber A A. The gear-wheel K, being attachedtoY the shaft of the carrying-wheel c, has a'movement in the same direction as the tread; and when the saidgea'r-wheel K is thrown in gear with the wheel M by the levervn, thegear-wheel M will have a movement in a contrary direction, and will carry with it the drive-wheel D in direction of the arrows in iig. 2.' When tliewheel K is thrown out of gear from the wheel M, andthe rollers r1' are thrown up by the` lever S, the middle line of coge, h h, will be thrown in gear with the Wheel 'M, and reverse its former motion and cause the' drive-wheel to turn back. If the wheel c be thrown in gear with the wheel M, while the said wheel M is in gear with the cogs 7i 7L of the tread, then the whole machine will be brought to rest.

The advantages of these improvements are these:

First. A simple reversible tread-power is produced which is completely undert-lic control of the tender..

Second. Cars can be drawn or propelled forward, or backed, or stopped with ease.

Having described my invention, what I claim, and desire to securle by Letters Patent, iss- 1.
