RAILWAY MOTOR HAND-CAR.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed March 11, 1909. Serial No. 482,786.

To all whom it may concern:

Be it known that we, WILLIAM S. HOVEY and hfljinrox H. Rix, citizens of the United States, residing at Three Rivers, Michigan, have invented certain new and useful Improvements in Railway Motor Hand-Cars, of which the following is a specification.

This invention relates to improvements in rail ay motor hand cars.

The objects of this invention are: First, to provide in a hand car an improved. construction in which the engine is conveniently arranged and located and effectively connected to the traction wheels. Second, to provide an improved motor hand car which is very simple and economical in structure, and one in which the driving connections are so arranged that they are not likely to be injured or disarranged in the lifting of the car to and from the tracks under various conditions, such as occur in practical use in the manipulation of a car of this type. Third, to provide a construction of motor hand cars in which there is little or no modification of the standard hand car in installing the motor, the parts being so arranged that changes in mechanism are slight and the car is substantially unencumbered when the engine is out of commission and the car is being drawn by hand.

Further objects, and objects relating tostructural details, will definitely appear from the detailed description to follow.

W' e accomplish the objects of our invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a side elevation of a structure embodying the features of our invention, a portion of one of the traction wheels being broken away to show the relation of the parts. Fig. 2 is a plan view of the car with the deck removed. Fig. 3 is a detail vertical section, taken on a line corresponding to the 5 broken line 33 of Fig. 1, showing details of the friction drive and means of controlling the same. F ig. a is an enlarged detail sectional view, taken on a line corresponding to line t4t of Fig. 3, showing the means for throwing the engine driving mechanism into and out of gear. Fig. 5 is a detail of the driving gear connections for the walking-beam to the traction wheels, the same being adapted to'be disconnected, and shown in the accompanying drawing with the connection broken. F 6 is a detail side elevation of amodified form of the drive, the tread being made use of as the friction member of the traction wheel, and the driving member being arranged outside the wheelf Fig. '7 is a detail plan view of the structure appearing in Fig. 6. Fig. 8 1s a detail, partially in section, taken on a line corresponding to line 1111 of Fig. 7. Fig. 9 is a detail side elevation of a further modification, spur gears being used instead of the friction gears shown in the other figures. Fig. 10 is a detail plan view of the structure appearing in Fig. 9.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body of our improved motor hand car preferably consists of the longitudinal sills 11 and 22, the sills 1 being the outer or side sills, and the sills 2 being the inner sills, arranged quite close together and forming the supports for the engine and the walking-beam driving mechanism. These sills are connected by cross pieces 3. The sills are provided at their ends with hand pieces 1, with which the car is lifted to and from the track. The car deck, which is not illustrated in any of the figures, excepting Fig. 1, is laid upon these cross sills, which are laid on top of the longitudinal sills. The platform is provided with side bars 5, which are arranged upon the cross pieces, as clearly appears from the drawing, thus making a light, but rigid, frame. This is a standard and com mon construction of hand car.

The traction wheels 6 and 7 are secured to the axles 8 and 9, respectively, suitable hearing, as 10, being provided on the one side of the outer longitudinal sills 1. The axle 9 is driven from the walking-beam 11. This walking-beam is mounted upon the gallows frame 12, which is mounted upon the central sills 2, to project up through the platform. 1 The details of the connections of the gears, such as bolts, and the like are not here illustrated as the same will be readily understood. The gallows frame 12 carries the hand lover or walking beam 11, with handles 13 at each end, and connected by the connecting rod 14: to the crank shaft 15 mounted in suitable bearings, as 16, on the central pair of sills. This is a usual and standard construction.

On the crank shaft 15 is a gear 17. On the axle 9 is a pinion 18 which is adapted to be slipped into mesh with the gear 17. A shift lever 19 for the pinion 18 is arranged at one side of the gallows frame, (see Fig. 1), and is provided with forks 20 at its lower end to engage the groove 21 in the hub of the wheel 18, which is splined upon the axle, (see Fig. 5). By this means, the walking beam, or hand driving means, can be readily thrown into and out of gear.

The engine is arranged in front of the gallows frame, the engine being mounted on the central longitudinal sills 2 and arranged in an opening through the platform of the car. The crank shaft is provided with a suitable balance wheel 2 1, which also projects through the platform. In this arrangement of the parts, the engine does not project below the platform sufliciently to be likely to be damaged in the handling of the car. The engine shaft 23 is connected to the driving shaft 25 by a universal joint 26, which enables the throwing of the friction driving gear 27 into driving engagement with the friction gear 28 on the hub of one of the traction wheels 6, or into driving engagement with the flange or tread of the wheel.

The driving shaft 25 has a bearing in the eccentric block 30 which is adjustable in the support 31. A hand lever 32, which projects up through the platform is provided for adjusting the block 30. A latch 3%, preferably in the form of a pawl, engages the notched segment to lock the lever in place. The latch is controlled by a hand piece 35 on said lever, which is connected to the latch by th rod 36. The eccentric block 30 is preferably provided with a bushing 37 for the shaft, and is embraced by a bushing 31. The friction gear 88 is secured upon the hub 39 of the traction wheel, the periphery of the gear being preferably V- shaped or convex in cross section. By this arrangement, the friction gear can be thrown into engagement with the friction wheel on the hub, or an appropriate friction surface of the tread or flange and the car can be quickly reversed, at a different speed, however. This variation of speed, however, is not of great importance in a structure of i this kind, which can be readily turned l about. It .13 sometimes found very desirl able to drive the car backward for a short distance without turning it around, especially where it is operated by one man or where a short trip in the I'GXYOISC direction is to be made. By this arrangement, the car can be driven by the combined action of the engine and the walking-beam, or by either. The fuel tank 5 1 is supported on the front of the gallows frame. The engine is preferably an explosion engine. Our invention enables the application of an engine to bodies of hand cars of the usual standard construction without great expense, and without materially modifying the same.

In the modified construction shown in Figs. (3, T and 8, the friction wheel 40 is arranged to engage the exterior tread surface of the traction wheel 7.

In the modification illustrated in Figs. 8) and. 10, toothed gears are provided inst id of the friction gears. A spur gear 41 is secured to the hub of the traction wheel in place of the friction gear 38, and a spur gear 42 is substituted for the friction gear 27. The reverse in this construction is secured by providing the engine shaft with a friction driving wheel 43 with which the driving wheel 44 on the shaft 15 is arranged to engage. The gear 1 1- is arranged to slide on the shaft 45 and may be moved past the center of the gear 13, thus controlling and reversing the same. The shaft is connected to the shaft by means of a universal joint 26, the shaft being here supported by an eccentric block the same as in the other structures, so that the pinion 42 may be thrown into and out of engagement with the gear 4:1.

For convenience in cranking the engine, we preferably provide a. cranking shaft 46 which can be engaged with a suitable crank through an opening in the web of the wheel opposite the wheel having the driving connection. The cranking shaft is, in effect, an extension of the engine shaft. The engine can also be started by throwing it into gear after the car has been started by hand. The walking-beam driving connections can be disengaged and the handle bar of the walking-beam then serves as a support for the person riding upon the car. A hook 47 is provided on the gallows frame for locking the walking-beam in a horizontal position. The brake shoes 18 are pivoted at 19 to one of the sills 1 and are connected by the links 50 to the rod 51 which is arranged to reciprocate in the bearing 52, the rod having a foot piece on its upper end, so that, by stepping upon the same, the brake shoes are thrown into engagement. They are so pivoted that their weight tends to throw them out of engagement when the actuating rod is released.

While we have described the engine as in front of the gallows frame, it is clear that it will be in the rear when the direction of travel is reversed.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is 1.
