To all whom, it may concern.'y i

Be itknown that I, THOMAS TALBOT, a sub-1 ject of vthe Queen of Great Britain, residing at Mattawa, inthe Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Hand-Cars `for Railways, of which the following is a full,

clear, and exactV description,such as will enable those skilled in the art to which it apsponding parts, Figurel is a perspective view.

of a hand-car embodying the invention.v Fig. 2 is a longitudinal vertical section. a transverse vertical section. Fig. 4 is a detailI view, showingthe brake mechanism.

.Referring to the'drawings by letter, A designates the platform of a car of any construction suitable in the premises, mounted inthe usual manner upon wheels.

13,13, `designate the standards which support the driving mechanism, and 'each consists ofthe inclined fu'prights 17,1), connected at their upper ends by the cross-piece. b. Between the upper ends of the standards, is the shaft D` ljournaled. at its ends in the journal boxes d, d, respectively secured to the cross-pieces b', b', of the, saidstandards. On this shaft is mounted 'the walking-beam The latter consists of the main lever e pivoted at an intermediate point, on the shaft D and the handles e e', respectively secured transversely to the endsof `the main lever. The main lever and handles are formed of sections of pipes suitably connected by T- couplings. v Mounted on the shaft D, atan intermediate point, are the rock-gears CZ, d', between which and above the shaft, the levere is secured. Immediately below the shaft D, a' second shaft F is Vmounted with its ends journaled in the boxes f, f, respectively se- 5o cured tothe under sides ofl the cross-pieces b', b', of the standards. On this shaft are Fig. 3 is mounted the rock-gears f', f. The rockgears f', f', mounted on the shaft F, and the -rock-gears d', d', mounted on the shaft D, have substantially the same constructions. Each consists of, a body, circular in form, and for a considerable distance, has gear teeth formed in its periphery, and it has a socket or seat d2 formed inone of its sides. The gears which areused on the upper shaftv are shown as forming the socket is extended to give a llongerbearing to the lever e. The gears of each pair are mounted so that their respectivesockets, d2, d2, will extend in opposite directions and Vopen toward each other. Between the upper gears, in the sockets formed therein, are secured the inner ends of the sections forming the main lever of the walkingbeam E. lt is to be observed that themain lever can be formed of a single section without requiring any change in the construction having a construction slightly dilferent from that of the lower, inasmuch as the portionk of the gears, and fthe gears themselves may/ be bolted together to secure greater stability.

Immediately below the rock-gears el', d', On the shaft D, are the lrock-gears f,f, on the shaft F and, meshing with the former. To

v these gears, are respectively connected the inner'ends of the intermediate levers H, H. These levers have somewhat of an SK-shape and have their inner ends seatedin sockets f formed in the rock-gears to whichvthey are respectively attached. y

l designates the main driving wheel. lt is a toothed wheel mounted upon ashafti Journaled atits endsin journal-boxesi?, t2, mounted on the longitudinal supports t3, t3, attached to The ends of the shaft project beyond their bearings and have attached thereto the crank arms 4, 4. The

outer ends of the latter are provided with wrist-pins upon which the lower ends of the rods t5,'5, are respectively journaled. l'lhese rods are connected at their upper ends with the outer ends of the intermediate levers H, H. The latter are so bent as to allow their outer ends to move in the same vertical planes as the wrist-pins of the crank arms t4, i4. The gear wheel Z meshes with `a similar wheel Z Imounted on the axle L2 of the forward truck.

The relative sizes of the gears Zand Z is five .beams of the car frame.

to one, which has been found to be the preferable arrangement.

The operation ofthe driving mechanism is as follows: By oscillating the walking-beam E, the intermediate arms H, II, through the connecting rock-gears, are also oscillated, but

in opposite directions, that is, when one end of the walking-beam is moving in one direction, the intermediate lever on that side is lnoving in an opposite direction, and thereby the connecting rods t5, t5, are reciprocated. By this movement of the connecting rods the gear wheel l is rotated, through the crank arms t4, 4, and through the gear Z' the shaft of the forward truck is also rotated, and in consequence the car is propelled.

A novel mechanism is provided whereby a powerful operation of the brakes can be secured. K designates a shaft mounted transversely of the car in suitable bearings, and provided at its ends with crank arms. To the latter brake shoes K', K', of any suitable construction are attached. In the present instance the brake shoes are formed of blocks of wood provided with metal faces, pivoted at their upper ends to the longitudinal side rlhey are respectively connected at their lower ends by links 7c, k, with the crank arms la', k', attached to the ends of the shaft K. The shaft K at a suitable point is provided with a crank arm h2, which is connected by the link 7c3, which passes upwardly through the platform, with the foot lever 7a4 pivoted at one end to one of the standards B. The free end of the foot lever moves in the loop h5 attached to the standard. A spring catch 7a is provided to engage with the free end of the foot lever to hold it in an elevated position when the brake is not in use. The foot lever is easily accessible from either side of the supports B, B, by means of the threads k7, k7.

The operation vof the brake is as follows: By pressing upon the foot lever, the shaft K is rotated through the link k3 and the crank arm k2. This movement of the shaft will cause a corresponding turning of the crank arms on the end of the shaft, and through the connecting links will force the shoes against their respective wheels.

A novel mechanism is also provided to aid in turning the car and in displacing the same from the tracks. A lever R is pivoted at one end to a substantial part of the car frame at a central point back of the supports B, B.

To this lever, near its pivoted end, the pivoting bar R is hinged at one end. This bar hangs beneath the platform and is of such a length that when it is held in a vertical position and the lever depressed the rear end of the car will be elevated so as to completely clear the tracks. In this way the car is plvoted, almost at its center, and the opposite end can easily be raised and turned. To hold the lever in its depressed position, a catch r is provided. The lever is so bent near its pivoted end, at the point where the rod is hinged, as to allow the latter to be turned up against the bottom of the platform when not in use, where it can be held by the bail r2.

The construction herein described can be departed from to a considerable extent with-l out departing from the spirit of the invention, as for instance, a single pair of rock gears one on each shaft can be used instead of two.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isy l. In ahand car,the combination of the rockgears mounted one above the other and meshing with each other, the walking-beam attached tothe upper of the said rock-gears, the intermediate levers attached to the lower of the said rock-gears, and the driving gear connected with the said levers, substantially as described.

2. In ahand car, the combination of the su pports, the shafts journaled therein one above the oth er, the rock-gears mounted on the same and meshing with each other, the Walkingbeam attached to the upper of the said rockgears, the intermediate levers attached to the lower of the said gears, the shaft journaled in the frame of the platform of the car, the main driving gear mounted thereon, the crank arms attached to the ends of the last mentioned shaft, and the rods connecting the ends of the intenmediatelevers with the crank arms, substantially as described.

3. In a hand car, the combination ofthe rockgears, arranged in pairs, one pair above the other, and each upper gear meshing with the one immediately below, the walking-beam s ecured between the gears forming the upper pair, the intermediate levers respectively attached at their inner ends to the gears forming the lower pair, and the driving mechanism connected with the said levers, substantially as described.

In testimony whereof Iaiiix my signature in the presence oftwo witnesses.

THOMAS TALBOT.
