TRUCK.

SPECIFICATION forming part of Letters Patent No. 650,629, dated May 29, 1900. Application filed March 9 1900- Serial No. 3,042. (No model.)

To all whom it may concern.-

Be it known that I, FRED E. BROWN, a citizen of the United States, residing at Chicago,- in the county of Cook and State of Illinois, have invented a new and useful Truck, of which the following is a specification.

The invention relates to improvements in trucks.

The object of the present invention is to improve the construction of trucks and to provide a simple, inexpensive, and efficient one designed especially for use around depots and the like and capable of being readily raised and lowered to elevate its contents, so that they may be conveniently transferred to a car or wagon or other elevated place.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a truck constructed in accordance with this invention, the upper section or platform being lowered. Fig. 2 is a longitudinal sectional View, the upper section or platform being raised. Fig. 3 is a transverse sectional view, the parts being arranged as shown in Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawlugs.

1 designates a lowerrectangular truckframe provided with front and rear axles 2 and 3, having wheels 4, the front axle being pivotally mounted and being connected with a tongue 5 of the ordinary construction. The rectangular truck-frame is composed of side and end bars and is supported at its front portion bya cross-bar 6. Between the sides of the truck-frame are pivoted the lower ends of links 7 and 8, consisting of substantiallyrectangular frames extending across the truck-frame and provided with upper and lower journals, the lower journals being arranged in suitable bearings of the side bars of the truck-frame. The links, which are parallel, extend rearward from the truckframe when an upper frame or platform 9 is lowered to the position shown in Fig. 1 of the drawings, and the upper journals of the links are arranged in suitable bearings of the side faces of the said bars.

bars 10 of the frame or platform 9. By means of the links 7 and 8 the upper frame or platof bars 13, located at opposite sides of the truck and pivoted to the outer .faces of the side bars of theupper frame or platform, at the front end thereof. The bars 13 are connected with the outer ends of the levers by means of a transverse rod 15, forming a handle-bar and adapted to be readily grasped to swing the levers downward to raise the platform or upper frame. The truck-frame is provided at its front with opposite brackets or supports 16, arranged to receive the levers 12 when the latter are swung downward to a horizontal position and consisting of a transverse-bar secured 'to the lower face of the front end bar of the truck-frame and extending beyond the sides thereof and having its terminals bent upward to form arms, which are spaced from the sides of the truck-frame.

The upper frame or platform is adapted to be arranged at different elevations, and it is prevented from dropping back by a hinged v brace 17, substantially rectangular, as illustrated, in Fig. 3 of the drawings, and provided at its bottom or engaging end with laterallydisposed projections 18, arranged to engage ratchets 19, located at opposite sides of the side bars of the truck-frame, at the inner The hinged brace is composed of side bars, pivoted at their upper ends tothe side bars of the platform or upper frame,- and transverse bars connectingithe side bars. The lower ends of the side bars of the hinged brace are perforated for the reception of the reduced ends of the rod 20, which forms the projections 18. The ratchets consist of bars secured to the inner faces of the sides of the lower or truck frame and provided with notches or recesses beveled at one side, as clearly shown in Fig. 2, and forming shoulders at the opposite side to be engaged by the said projections 18 of the hinged brace. The last recess or notch 19 of each of the rack-bars is provided with vertical walls forming opposite shoulders adapted to hold the projection 18 of the hinged brace against movement in either direction. This prevents the upper frame or platform from being drawn forward too far.

The hinged brace is disposed at an inclination when in engagement with the ratchets of the lower or truck frame, and it is adapted to be readily lifted out of such engagement by a rock-shaft 21, extending longitudinally of the truck-frame and provided at the front thereof with a handle 22 and journaled in 1 suitable bearings of the connecting-bars of the truck-frames. The handle 22, which is arranged at the front end of the rock-shaft, consists of a suitable grip secured to an arm of the rock-shaft. The front end of the rockshaft is extended upward to provide such arm, and the handle or grip, which extends forward or outward from the outer portion of the arm, forms a loop and is adapted to be readily grasped by the operator. The rear end of the rock-shaft is journaled in a suitable bearing of a transverse bar 23, secured to the lower edges of the side bars of the truck-frame. The rock-shaftis provided with a crank-bend 24:, extending from the transverse bar 23 to the intermediate cross-bar, and is of substantially the same length as the ratchets, being adapted to engage the bottom of the hinged brace when the projections 18 are in any of the notches or recesses. The crank-bend is adapted to swing the lower ongaging end of the hinged brace upward, and it provides a smooth surface, along which the brace slides as the platform or truck-frame is lowered.

' The handle 22 of the rock shaft is arranged withina bracket or keeper 25, consisting of a plate having inclined arms 26 at its ends tosupport the handle of the rock-shaft and to prevent the same from dropping below the plane of the truck-frame and to support the crank-bend in position for disengaging the hinged brace. v

- g It will be seen that the truck is simple and comparatively inexpensive in construction, that it is especially adapted for use at depots and analogous places, and that it iscapable of being arranged close to the ground or other supporting-surface to receive a load and of being readily swung upward to elevate the load on a level with a car, wagon, or other elevated place, so that the contents of the truck may be conveniently transferred therefrom to such car or wagon. Furthermore, it will be seen that the lower end of the hinged brace may be readily disengaged from the lower truck-frame to permit the upper frame or platform to descend and that the rock- .ing upper and lower frames, links connectshaft is supported by the bracket or keeper in position for holding the brace out of engagement with the ratchets.

What is claimed is-- 1. A device of the class described comprising upper and lower frames, links connecting the frames, a brace hinged to one of the frames andengaging the other to maintain the upper frame in its adjustment, and a rock-shaft arranged to engage the brace to release the upper frame, substantially as described.

2. A device of the class described comprising upper and lower frames, links connecting the frames, a brace hinged to the upper frame and arranged to engage the lower frame to support the upper frame in an elevated position, and a longitudinal rock-shaft mounted on the lower frame and provided with a crank-bend arranged to engage the brace and hold the same out of engagement with the lower frame, substantially as described.

3. A device of the class described compris- 9O ing the frames, a brace hinged to the upper frame and arranged to engage the lower frame, a longitudinal rock-shaft mounted on the lower frame and provided with a crankbend and having an arm, and a bracket or keeper arranged to receive the arm and provided with opposite arms or portions for supporting the rock-shaft and for limiting the, movement thereof,substantially as described.

4. A device of the class described comprising upper and lower frames, links connecting the frames, ratchets mounted on the lower frame at opposite sides thereof, a brace hinged to the upper frame and provided with projections for engaging the ratchets, and means for disengaging the brace, substantially as described.

5. A device of the class described comprising upper and lower frames, links connecting the frames, levers fulcrumed on the lower frame at opposite sides thereof, bars pivoted to the upper frame, and a transverse rod c011- necting the outer ends of the bars and the levers and forming a handle, snbstantiallyas described.

6. A device of the class described comprising a truck-frame provided 'at opposite sides with brackets, a platform, links connecting the platform with the truck-frame, levers fulcrumed on the truck-frame at opposite sides thereof and arranged to be supported by the brackets, and bars connecting the levers with the platform, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses. I

FRED E. BROXVN.
