T'.*F.A KRAJEWSKL WHEBLED VBHIGLL;
` 4818,289,421. Patented Deo. 4, 1888.
fi is STATES THOMAS F. KRAJEVSKI, OF PATERSON, NEV JERSEY.
WHEELED VEHICLE.
SPECIFICATION forming part of Letters Patent No. 289,421, `dated December 4, 1883,
Application filed June 18, 1883.
T0 all whom, t may concern,.-
Be itknown that I, THoMAs F. KRAJnwsxr, of Paterson, in the county of Passaic and State ofNew Jersey, have invented a certain new and useful Improvement in Vheeled Vehicles, of which the followingpis a specication.
My improvement relates particularly to vehicles which are adapted for traveling upon the ground or along rails.
In the accompanying drawings7 Figure 1 is a plan of a vehicle embodying my improvement. Fig. 2 is a longitudinal section thereof. Fig. 3 is an end view thereof, and Fig. 4 is a transverse section of the same.
Similar letters of reference designate corresponding parts in all the gures.
The frame A A""`A2 A3 of the body or platform of the vehicle is made, as here shown,of beams or girders A,which are -shaped in the cross-section, and may be constructed of iron or other suitable material. These beams or girders are connected at the ends by anglepieces and bolts"l or other suitable means. Beams or girders A2 extend lengthwise of the frame, and may be channel or trough shaped in the cross-section- Beams or girders A3 extend between the beams or girders A2. Between the beams or girders A and the beams or girders A, which are parallel therewith,extend beams or girders A3. This frame A A A2 A3 may be covered with planks or other material.
B designates the Wheels of the vehicle, and C designates the axles of the wheels. wheels B have wide treads c, circumferential grooves b, and ilanges c. The grooves b are sufficiently wide to fit uponordinary railroadrails D, the treads a are located at the outer sides of the grooves, and the flanges c are arranged at the inner sides of the grooves. Owing to this relative arrangement of the grooves, treads, and flanges, a greater space is provided between opposite wheels than would otherwise exist. The increase of this space is advantageous because it enables the wheels the better to clear stumps, projecting stones, `or irregularities in the surface of the ground between the rails. Moreover, the arrange ment of the treads at the farthest possible distances apart is advantageous when the vehicleis removed from the rails and run over rough ground, for the body or platform of the The (No model.)
The hubs of the wheels may y flanges c haveuio greater circumferential extension than the treads, and hence will not sink into the ground farther than the treads.
The axles C may be made of wrought-iron or other suitable material. They are provided with shoulders e near the ends, or, in other words, just in rear of the journals f. On the journals f, between the shoulders e and the wheels B, are collars g, and outside the wheels B other collars, h, are placed on the journals. Linchpins i," passed through the journals outside the wheels and the collars h, secure the wheels in place on the journals. The axles just inward of the journals fare bent upward, and the central portion extends parallel with the journals, but is elevated considerably above the same. The elevated central portions of the axles are pivoted by center pins or king-bolts, E, to the beams or girders A2 of the frame A A A2 A3; hence the pairs of wheels may be adjusted at different angles relatively to the frame A A A2 A3 for the purpose of facilitating the turning of the vehicle. As shown, these pins or bolts Eare provided with clips j,embracing the axles,and secured thereto by bolts or rivets, and extend through the beamsuor girders A2, and are secured thereto by nuts n. The elevation of the central portions of the axles is advantageous, because it enables them to clear stumps,stones, and other projections from the ground, and also because it enables the axles to be con nected directly to the frame of the body or platform of the vehicle. rIhe wheels of the peculiar construction here shown, and the axles having the elevated central portions, both conduce to allow ample clearance below the axles, the wheelshaving the outside treads giving a wide clearance laterally, and the axles with their elevated portions allowing clearance in a vertical direction.
A forked drawbar, G G', is connected to IOO each of the'axles C. Each draw-bar has two diverging arms, G, which are provided with clips k, that embrace an axle and are bolted or riveted thereto, and an arm, G, that extends in an opposite direction beyond the frame A A A'l A". The arm G is bifurcated at the outer end and provided with holes Z,into which a coupling-pin, p, may be inserted. Under each of these arms G extends a guide-rod, o, which supports the arm, and yet allows it to move laterally. The ends of the rods 0 are fastened to the transverse beams or girders A of the frame A A A2 A3. The arms G of the forked draw-bars extend beyond the axles C, and at the .ends are connected by rods H. These rods are arranged in different planes, and cross each other so as to extend between obliquely-opposite arms. At the ends the rods are bifurcated, so that they will embrace the ends ofthe arms G of the draw-bars, and they are connected to these arms of the drawbars by pins fm. Vhen either draw-bar is moved laterally to swing around the pair of wheels and axle to which it is connected, th-e rods H cause the other pair of wheels and axle to also swing around, so as to facilitate the movement ofthe vehicle around a curve. On the upper side of the arms G of the draw-bars are projections q, and on the lower side of the beams or girders A2 are stops r. Vhenever the pairs of wheels and their axles are swung around sufficiently in moving the vehicle around a curve, some of the projections q on the draw-bar come in contact with the projections r on the beams or girders A2, the wheels and axles are precluded from swinging around any farther. The upper sides of the arms G of the draw-bars form bearings on which the projections or stops r on the car-frame move, and therefore form side bearings for supporting the frame. rllhese bearings do not prevent the frame from being readily lifted off the axle when the king-bolt or center pin,E,is removed. The stop projections r may be considered as a part of the frame.
Vhat I claim as my invention, and desire to secure by Letters Patent, is-
l. In a wheeled vehicle adapted for traveling over the ground or along rails, the combination, with an axle, of two wheels mounted thereon, severally having at the outer edge a wide tread suitable for running over the ground, the said tread being approximately straight from side to side and destitute of a flange, a groove located at the inne-r edge of the tread suitable for fitting a rail, and a ila-nge forming the inner side of the groove and extending circumferentially no farther than the tread, the said wheels being so arranged relatively to each other that their anges and grooves will be inward of their broad treads, substantially as specified.
2. `In a vehicle designed for traveling over the ground or along rails, the combination of an axle having a central elevated portion, and apair ofwheels having at the outer edges Wide treads, which are approximately straight from side to side and destitute of flanges, and which are suitable for running over the ground, having grooves at their inner edges, and having flanges forming the sides of the grooves opposite the treads and extending no farther circumferentially than the treads, substantially as specified, whereby an increased clearance is afforded beneath the axle both in a vertical and `lateral direction.
3. In a vehicle, a frame for a body or platform, an axle having its central portion elevated, a center pin or king-bolt connecting the central elevated portion gf the axle to the frame, and side bearings on the elevated portion of the axle on which said frame rests, all beingso combined and organized that provision is afforded for raising said frame off the axle when the said pin or bolt is removed, substantially as described.
4. In avehiele, the combination of a plat-V form or body, an axle, a forked draw-bar connected thereto, projections extending upwardly from the draw-bar, and projections extending downwardly from the platform or body, substantially as specified.
