SPECIFICATION forming part of Letters Patent No. 462,509, dated November 3, 1891.

Application filed May 2'7, 1891.

T 0 all 10700722. it 7220.;1 concern:

Be it known that I, CYRUS ROBERTS, acitizen of the United States, residing at Three Rivers, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Hand-Oars, of which the following is a specification, reference bei n ghad therein to the accom pan ying d rawings.

This invention relates to new and useful improvements in hand-cars of that class especially designed for light work and high speed, generally known as inspection-cars.

The invention consists in the peculiar construction of the frame, the axles, and the drive mechanism, and, further, in the peculiar construetion, arrangement, and combination of the various parts, all as more fully hereinafter described and shown.

In the drawings, Figure 1 is a side elevation of my improved car with the wheels removed. Fig. 2 is a bottom plan view thereof, partly in section. Fig. 3 is a vertical cross-section on line was in Fig. 2. Figs. 4 and 5 are detail views specifically referred to.

The frame of my car consists of two longitudinal beams A, covered with a suitable platform B. This frame is supported by means of suitable wheels (1. There are two pairs of wheels, one pair forming the dllVB'WllGGlS and the others being simply loosely secured upon their axles, the drive-wheels upon the shaft D running in boxes E. These boxes are provided on the top and bottom, respectively, with a gain or notch F, in which the end of the trussed frame G engages, as shown in Fig. 4, this frame consisting of two oppositelycurved bars, being secured in position atthe ends by means of the bolts which secure to gether the two halves of the axle-box. The body of the car is supported upon the top of this trussed frame in any suitable manner. The other pair of wheels are supported upon stub-axles II, which pass through the boxes II, and are prevented from being disengaged therefrom by means of a head 1, bearing against the inner sides of the boxes. These boxes are connected together by means of a similar trusscd frame I, which at suitable in tervals is held rigidly in position by means of struts J and clam ping-bolts K. These bolts pass through the strut, truss, and platform Serial No. 394,308. (No model.)

and clamp the whole together, as plainly shown in Fig. 3. The platform is of considerably less width than the distance between the wheels to give the requisite lightness.

The timbers A are trussed by means of trusses, which consist of a central arched portion K between the axles or axle-frames, and the two end braces K extend from these axle-frames to the bars A. The two axleframes are connected together by means of auxiliary platforms K which form a part of the truss for the frame, acting the part of a chord connecting the two axle-frames.

L is a shaft journaled centrally of the car upon boxes L, secured to the auxiliary platform by suitable bolts M and sleeves M, which pass through the platform and serve to support the auxiliary platform at that point.

N are vertical levers engaging into any suitable sockets formed in the end of the shaft. These levers N are connected together by means of the cross'barN. The drive-axle I) is provided with a drive-pinion 0 at one end, with which a gear-wheel P engages, this gearwheel being of suitable size to give the proper speed to the shaft. The gear-wheel P is journaled upon the shaft 1 extending across the platform beneath the same, provided at one end with a crank Q, with which the connect ing-rod Q, engages, and at the other end upon the opposite side of the frame bearing a gearwhcel 1, upon which a crank-pin R is secured, with which the connecting-rod R engages, all so arranged that the oscillating movement of the levers N impart through the connecting rods Q R a rotary motion to the gear-wheel I, which in turn actuates the driveshaft I),

which carries the drive-wheels of the car. I

obtain by this construction a very light car which will carry a large load, and also get a direct connection for my power to the driveshaft, whereby with the least exertion I may get a high speed, the auxiliary platform serving with a comparatively small amount of added cost and weight to permit of carrying a large load of light stuff-such as lanternswithout detracting from the room on the plat form proper, and they also serve as a part of the truss for the frame by connecting the axleframes.

3y making the axle-frames in the manner described in connection with the stub-axles at one end I lighten the car without lessening its capacity to carry loads.

What I claim as my invention is-- 1. In a hand-car, the combination, with the axles extending across the same, of trussed frames located above and below the axles, axle-boxes to which the frames are secured,

and a platform on the frame, substantially.

as described.

2. In a hand-car, the combination, with the axles, of trussed axle-frames secured at their ends to the axle-boxes and platforms above and below the frames, substantially as described.

In a hand-car, the wheels, the axles journaled in axle-boxes, axle-frames formed of oppositely-curved bars engaging with the top and bottom of the axle-boxes, and a platform supported thereon, substantially as described.

4. In a hand-car, the combination, with the longitudinal platform-timbers, the axle-frame formed of oppositely-curved bars engaging-at the ends with the axle-boxes, and of trussbars for the platform-timbers secured to the axle-frames, substantially as described.

5. In a hand-car, the combination, with the platform, the axle-frames extending beyond the platform, and the auxiliary platforms supported on said extensions below the main platform, substantially as described.

6. In a hand-car, the combination, with the axles, of frames supported thereon, a platform above the axles, and a platform suspended from and located below said other platform and having its ends connected with the frames, substantially as described.

'7. In a hand-car, the combination, with a platform and the axles, of a shaft extending below and across the platform, a hand-lever secured to the end of the shaft at one side of the platform, a shaft extending across the end of the platform, a gear-wheel mounted on said shaft, a crank on the shaft, a connectingrod between the lever and the crank, and a 5 I
