B. L. KEITH. WAGON BODY LIFTER.

Patented July 2 u; FETER$ Pholwlilhngmphe UNITED STATES PATENT OFFICE.

ROBERT L. KEITH, OF BRAZIL, INDIANA.

WAGON-BODY LIFTER.

SPECIFICATION forming part of Letters Patent No. 406,352, dated July 2, 1889.

Application filed February 20, 1889. Serial No. 300,563- (No model.)

To all whom it may concern.-

Be it known that 1, ROBERT L. KEITH, a citizen of the United States, residing at Brazil, in the county of Clay and State of Indiana, 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.

My invention relates to wagon-body lifters; and it consists of such means and their arrangement, as hereinafter described and claimed, as will simplify and render more efficient this class of inventions.

My invention is illustrated in the accom panying drawings, in which- Figures 1 and 2 are side and end views, respectively, in elevation, and Fig. 3 a plan.

Referring to the drawings, the frame for supporting the lifting device is composed offour vertical posts A, each pair of which are united by a top cross-piece B.

C C D D represent, respectively, the side and end pieces of a frame, to which the lower ends of the vertical posts are secured, which frame may be set in or on the floor or ground, or the vertical posts may be tenoned into the floortimbers of a barn or shed.

F is a windlass journaled in brackets G, that are secured to the top cross-pieces B, with one end of the Windlass extending beyond the frame and provided with handles 71.

I is a ratchet secured to the Windlass between the handles h and the frame, and controlled by a pawl K, pivoted to a cross-piece B.

M is a brake pivoted to a bracket Z on crosspiece B.

The brake M is provided with a grooved or cut-out portion m, adapted toclose upon the Windlass at the point m and is also provided with a cord m and handle or, with which to operate it.

P P are hanging frames, each composed of two upright and two cross pieces, and each suspended directly from the Windlass by a cord 5. WVhen not in use the frames P are drawn up to the windlass and there held.

WVhen it is desired to raise a wagon-body, the wagon is driven between the posts A,the frames P lowered and placed under the ends of the body, and the Windlass turned until the body is raised to the desired height, where it is held by the pawl engaging with the ratchet. When it is desired to lower the body, the pawl is raised; but to prevent the sudden fall the brake M is applied, by which not only the force of the fall is controlled, but the body can be held at any point;

The form of the lifting-frames P is advantageous, as they serve as cages, extending under the body its entire width and supporting the sides, thus providing for a uniform strain and support and being superior to hooks, or to lifts having but a bed-frame with chain or cords attached thereto, which are aptto scratch or other wise injure the body and to yield to strain and slipping at diiferent points.

It will be seen that my apparatus can be readily used to hoist other objects than wagonbodies.

lVhat I claim is-.

A wagon-body lifter consisting of the frame composed of the uprights and cross-piece A B, side and end pieces 0 D, in combination with a single Windlass F on the top of the frame, the handles, brackets G, secured to the cross-piece B, and in which the said Windlass is j ournaled, the ratchet I, secured to the said Windlass F, and pawl K, pivoted to the top cross-piece B, the hanging frames P P, com- ROBERT L. KEITH.
