WAGON-BODY HOIST.

SPECIFICATION forming part of Letters Patent No. 642,856, dated February 6, 1900.

Application filed October 25,1899. Serial No. 734,772. (No model.)

To all whom it may concern.-

Be it known that LTHOMAS H.TABOR, a citizen of the United States, residing at Ellijay, in the county of Gilmer and State of Georgia, have invented certain new and useful Improvements in Wagon-Body Hoists, of which the followingis a specification,reference being had therein to the accompanying drawings.

This invention relates to machines for lifting wagon-bodies.

The object of the invention is to produce a machine of the character stated in which a portable frame is provided, which frame can be quickly applied to the wagon-body and clamped thereto and which frame is adapted for use with wagon-bodies of various sizes and shapes. The clamping or inclosing frame is of such construction that much of it can be repaired or replaced by materials such as a farmer has at hand. Part of the device is also adapted for use as a wire-puller and the invention consists in certain constructions and combinations of elements, substantially as hereinafter described and claimed.

Figure 1 is a side elevation of the machine as adapted to a wagon-body, a part being broken away. Fig. 2 is an end elevation of the clamping-frame. Fig. 3 is a side elevation of the Windlass and part of the frame. Fig. 4. is a broken elevation of a modification of one of the frame-bars. Fig. 5'is a broken detail of part of frame and body-clamp.

The wagon-body A is supported near one end, preferably the front, by a loop B, passed around the body and connected to rope O, which passes over pulley D, as is common. Pulleys D D are suspended in any suitable way from an overhead support E, the pulleys being preferably tied to said support. Rope 0 leads to the Windlass on the box-clamping frame, which will now be described.

The clamping-frame consists of two side bars F F; One of the-bars may be a single strip of wood or metal, as shown in Fig. 2 at F; but preferably these bars will be in two sections F and F, as shown in Figs. 2 and 4. The two sections may be connected by bolts G G,-and by having a number of holes through which these bolts may pass or by having one of the strips slotted the length of the side bar may be adjusted to various conditions of use. Each side bar'will have a hole or mortise H near the lower end, and a bar I may be passed through both mortises, so as to extend under the wagon-body. The bar I may be held in place by keys; but this is generally unnecessary.

At or near the top of one of the frame-bars, as at F Figs 2 and 3, a Windlass-gear is attached. By preference this gear consists of a crank-shaft K,which has one bearing in the frame-section F and the other in a strap or housing L; A pinion M on the crank-shaft is thus inclosed between the housing and the side bar, and this pinion can be revolved by turning crank K.

Pinion M engages a second and preferably larger pinion N, which is on the short shaft N, having bearings in the frame-section and housing. Outside the housing a ratchet wheel N is placed on the shaft and held against rotation in one direction bya pawl N The short shaft N has a socket or offset N inside the side bar F and a Windlass-shaft 0 may be attached to this socket by bolts or otherwise. The other bearing of the windlass-shaft is in the other side bar of the frame. Thus the two side bars and the cross-bar I and Windlass 0 (completed by its shaft) form an open rectangular frame adjustable as to height by lengthening or shortening the side bars or by passing bar I through different mortises and adjustable as to width by moving one of the side bars along the cross bars or cylinders I O.

Rope O is attached to Windlass bar or barrel 0 and supports the frame,which may be swung conveniently from the pulley, so as to inclose the end of the wagon-body, having been once adjusted to the size of said body.

' A simple L-shaped clamp P forms a convenient holder, one end of said clamp resting against the side bar and the other extending inside the wagon body, a bolt G passing through the clamp and side bar andserving to tighten the same against the wagon-body when desirable. The frame is first adjusted so as to nearly fit the wagon-body, and then the clamps are applied.

As the Windlass may be made to consist of merely the housing, shafts, and gearing in metal, the side bars being made of Wood and readily attachable thereto, it is apparent that a farmer of ordinary skill may readily replace nearly all parts of the frame at small expense. The manner of using the device for lifting a wagon body will be understood by any person skilled in this art.

The Windlass and section F of the side bar form a very convenient and efficient Wirestretcher when detached from the remainder of the device.

What I claim is 1. In a wagon-body lifter, the combination with a supporting-rope and pulley, of an adjustable rectangular frame adapted to surround the Wagon-body at one end, a Windlass connected to one side of said adjustable frame, and clamps connected to the frame in position to attach the wagon-body, substantially as described.

2. In a Wagon-body lifter, the combination with the adjustable frame for inclosing the Wagon-body, of the clamp-pieces secured to the side bars of said frame, and the adjustingbolts passing through said clamp-bars and side pieces, substantially as described.

3. In a Wagon-body lifter and in combination, a frame-section having a hole therein and a Windlass-bar passing through the hole and provided with means for attaching a shaft thereto, said frame-section having means for attaching a further section to complete the frame-bar, a housing outside the frame-section, a pinion on the Windlass-bar between the frame-section and housing, a crank and a driving-pinion in mesh with said pinion on the Windlass-bar, and a pawl connected to the housing and engaging one of said pinions to serve as a stop,whereby the frame-section and specified adjuncts are adapted for use as a stretcher, or for completion by the'attachnlent of other parts, all substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
