wAe'oN-BoDY LIFTER.

SPECIFICATION forming part of Letters Patent No. 573,719, dated December 22, 1896.

Application filed OGObeI 22, 1896. Serial. 6091668. (NO model.) i

To all when@ it may concern:

Be it known that I, EDWIN J. STRONG,a citizen of the United States of America, residing at Plover, in the county of Pocahontas and State of Iowa, have invented certain new and useful Improvements in VagOn-Body Lifters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to wagon-body lifters, and is designed more especially as an improvement upon my prior patent, dated July 2l, 1896, No. 564,459.

The present invention consists in the general construction of the apparatus, including certain details, all as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings7 forming part of this specication, Figure l is a side elevation of the apparatus with the parts in position to raise a wagon-body of the box type. Fig. 2 is a side elevation showing the position of the parts with the box or wagon-body elevated out of engagement with the runninggear of the vehicle. Fig. 3 is a plan view of Fig. l. Fig. 4 is a detail view of the open frame which is used in connection with the wagon-box. Fig. 5 is a longitudinal sectional view showing the application of the apparatus for raising a hay-frame from the runninggear, the parts being in the position corresponding with Fig. l. Fig. 6 is a plan view of Fig. 5.

The apparatus to be hereinafter described is located in a shed or other structure the ground or floor of which is preferably downwardly inclined rearward in order that the vehicle may be easily backed into position.

Referring to the drawings, the letters A designate the four corner-posts or uprights, which support the apparatus,said posts being located on each side of a driveway of sufficient width to accommodate an ordinary vehicle, and this driveway is preferably provided with parallel rails s s, that act to guide the vehicle into proper position between the posts A. The posts on each side of the driveway are connected by a longitudinal beam B, which is mounted upon the upper ends of said posts and rigidly secured thereto. Near the lower end of each post A are pivoted levers O, one oneach side, and between the upper ends of these levers are pivoted longitudinal beams D, that normally rest upon the longitudinal beams B, the levers O being connected to the posts A and beams D in such manner that the latter may be elevated a suitable distance above the stationary beams B when said levers are swung to a vertical position, stops l) being secured to the forward ends of the stationary beams to limit such movement.

E E designate latches or notched bars, one being pivoted to the outer side of each movable beam D, and the notched ends e of these latches are adapted to engage pins b', which project from the stationary beams B, such engagement being accomplished when the beams D are elevated to their highest point, and in order to prevent accidental disengagement of said latches the beams B are provided with holes so located that the removable looking-pins b2, which engage therewith, will bear upon the lower ends of the latches.

XVhen the apparatus is intended for use in raising a wagon-box from its running-gear, Figs. l, 2, and 3, stop-blocks CZ are mounted upon the movable beams D, and a cross-piece T is placed upon the beams to bear against said stops and against a cross-piece t, secured to the under side of the wagon-box. In this connection the movable beams are also provided at their rear ends with uprights F, having bearings at their upper ends for a crossbar G, carrying depending members g g, connected by a lower cross-barA g' to present an open frame which embraces the rear end of the wagon-box. a transverse shaft H,' having spools h h, around which are wound flexible connections 72.', extending from the free en ds of the latches or notched bars E, the shaft having a crankhandle for turning the same. This arrangement provides for simultaneously operating both latches. In raising the wagon-box from its running-gear the vehicle is first backed into the driveway between the posts A and The uprights F also support 9 IOO parts carried thereby, and when in position with the rear end of the box in engagement with the frame carried by the cross-bar G the cross-piece T is passed under the forward end of said box to engage the stops el, carried by the movable beams D, and the cross-piece z., secured to the under side of the box. In this position a pawl U, which is pivoted to the under side of the wagon-box, is dropped to engage the rear bolster ofthe running-gear, and then by wheelin g the vehicle forward the pawl will act upon the wagon-box to push it forward, which movement being communicated to the beams D by the intervention of the cross-piece T will swing the levers C to a ivertical position, thus elevating the beams D and wagon-box carried thereby, in which p0- sition the parts are held by the latches or notched bars E engaging the pins b. It will be understood that as the wagon-box is raised the loops at the sides will disengage the standards of the running-gear, and when elevated the box will rest upon the cross-pieces T and g. It will also be understood th at as the operation of raising the wagon-box depends principally upon the cross-piece T the whole wagon .could be wheeled out by simply removing said cross-piece. In replacing the wagon-box the running-gear is backed into position and the pawl U dropped to engage the rear bolster. Then by raising the latches E the weight of the box, in connection with that of the movable parts of the apparatus, will lower said box and simultaneously back the running-gear, this operation being augmented by the inclination of the floor.

Vhen the apparatus is arranged to raise a hay-frame from its running-gear, the stopblocks d, uprights F, and parts carried by said uprights are all removed, and after the vehicle has been backed into position with the cross-pieces of the frame located above the movable beams D swinging stops K at the forward ends of said beams are thrown to a vertical position to engage the forward cross-piece of said hay-frame, and after the pivoted pawls V are dropped into engagement with the rear holsters a forward movement of the vehicle will elevate the hay-frame and beams D by said pawls pushing upon said hay-frame and the latter pushing upon the beams through the intervention of the stops K. These stops abut against pins 7c to prevent them swinging beyond a vertical position.

In connection with the wagon having the rusual box-frame I prefer to use the pawl illustrated more clearly in Fig. 3, which consists of side members pivoted to blocks secured to the under side of the box-frame and having a cross-bar that engages the bolster, an d in connection with a hay-frame two pawls are preferably used, each consisting of a bar pivoted to one of the intermediate longitudinal beams and having a notched end which engages the bolster.

The deviceherein shown and described provides a very simple, cheap, and effective apparatus, which .can be readily adapted for raising either an ordinary box-frame or a hayframe, and by providing the double levels C the movable beams B will be braced against lateral movement. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
