WAGON-BODY LIFTER.

SPECIFIGATIGN forming part of Letters Patent No. 707,466, dated August 19, 1902.

Application iiled November 21, 1901. Serial No. 83,161. (No model.)

T0 all whom, it mfc/y concern:

Beit known that I, GEORGE H.WADE, a citi- Zen of the United States,- residing at Greeley, in the county of Greeley and State of Nebraska, 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 skilledin the art to which it appertains to make and use the same.

This invention relates to the variety of hoisting mechanism specially designed for lifting wagon-bodies, hay-racks, and the like from running-gears to admit of the latter being variously used.

The invention resides in the particular construction of the crane,whereby the upper portion of the post is adapted to be turned and the outer end of the jib capable of vertical adjustment, the parts being braced in their several adjustments.

For a full description of the invention and the in erits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is t be had to the following description and drawings hereto attached.

While the essential and characteristic features ofthe invention are susceptible of modication,still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a Wagonbody lifter constructed in accordance with this invention and showing it'in operation, the dotted lines indicating the position of the jib when turned so as to throw the wagonbody out of the way. Fig. 2 is a side elevation. Fig. 3 is a detail View showing the operation of the clamp. Fig. 4 is a detail view of the joint and clamp. Fig.l 5 is a View similar to Fig. 4 at a right angle. Fig. G isa detail view in perspective ot' the Windlass and adjuncts.

Corresponding and like parts are referred to in the following description and indicated in all the views ot' the drawings by the saine reference characters.

The crane comprises a sectional post and a pivoted jib, the post being mounted upon a suitable base and braced, so as to resist lateral strain.

While the base may be of any form and construction, it is shown as consisting of crossed bars or timbers 1 and 2, the post being attached at its lower end` to the said base-timbers at their point of crossing. The post comprises a lower fixed section 3 and an upper section 4 in line with the fixed section and mounted to turn thereon about a vertical axis. Within the broad spirit of the in" vention the manner of journaling the section 4 upon the section 3 is unimportant so long as a substantial joint is formed to resist the weight of the load. In the preferable construction the upper end of the fixed section 3 is ironed, being provided with a metal cap 5, centrally apertured to receive a journal (i, pendent from a metal cap 7, fitted to the lower end of the section 4. The fixed section 3 is braced by stays 8 and 9, interposed between it and the crossed timbers 1 and 2. The section 4 is stayed by braces 10, having their lower ends tirmlyconnected to the basetimber 1 and their upper ends attached to a ring 11, encircling the section 4 at a point between its ends. By having the section 3 braced in the manner stated and the upper section 4 journaled in a substantial manner to the section 3 and stayed by the braces 10 the post is firm and not liable to lateral displacement when the crane is supporting the load.

The jib 12 has pivotal connection with the section 4 by means of a pin 13 and is held in the required adj usted position by means of a brace 14, having pivotal connection at its upper end with the jib and adjustable connection at its lower end with the post. This construction admits ofthe outer end of the jib being vertically adjusted to regulate the lift ot the crane for wagons of different height or for any other desired purpose. The lower end of the brace 14 has pivotal connection With a angling with reference to the sides of the post,

as shown at 15, so as to grip the post in the manner stated. Upon lifting the end of the band having the brace 14 attached the opposite end will drop and automatically release the post, thereby permitting the band to be moved up or down to the desired position, and when released the band will assume the position about as shown in Fig. 3 and grip the post and hold the brace 14 and j ib 12 in place. A pulley 16 is mounted upon the pivot-pin 13, and a corresponding pulley 17 is located at the outer end of the jib l2. The hoistingrope 18 passes over the pulleys 16 and 17 and through a sheave-pulley 19 and has one end attached to the jib 12 and its opposite end adapted to wind upon a windlass 20, journaled to the fixed section 3 of the post. The vertical portion of the hoisting-rope passes through the joint between the sections 3 and 4 of the post and does not in any wise interfere with the free turning of the section 4 when it is required to swing the jib 12 either to the right or to the left. The windlass is provided with a gear-wheel 21, which intermeshes with a pinion 22, secured to a shaft 23, having a crank 24, by means of which the said shaft is rotated for turning the windlass either to the right or to the left, according as it may be required to wind the hoisting-rope upon the windlass or unwind the same therefrom. A detent mechanism coperates with the shaft 23 to prevent rotation thereof when the crank 24 is released, and this detent mechanism consists of a ratchet-wheel 25 and a pawl 26, arranged for cooperation therewith.

As shown in Fig. l, the body 27 of a wagon is connected with the sheave-pulley 19 by means of four ropes 28, one being attached to each corner of the body, and after the body has been loosened from the running-gear it can be elevated by rotation of the windlass 20, upon which the lower end of the hoistingrope is mounted. After the body has been ,lifted so as to clear the running-gear it may be turned out of the way by swinging the jib 12 either to the right or to the left, so as to occupy the position about as shown by the dotted lines in Fig. 1. The wagon-body may be lowered upon the ground and the' crane used for lifting a hay-rack, wagon-body, or other part from the running-gear of another wagon, and the part thus elevated may be in a like manner placed upon the ground out of the way. When it is required to replace the body upon the running-gear, the same can be readily effected without interfering with any other body or part placed upon the ground. The construction is such as to admit of the crane being used in connection with a number of running-gears, as will be readily comprehended.

Having thus described the invention, what is claimed as new is- 1. In a Wagon-body lifter, a crane comprising a j ib, hoisting-tackle, a sectional post, and braces, the lower section ofthe post being fixed and the upper section being journaled thereto to turn about a vertical axis, and braces between the upper turnable section of the post and the support upon which the crane is placed, substantially as set forth.

2. In a wagon-body lifter, a crane comprising a j ib, hoisting-tackle, a sectional post having its lower portion fixed and its upper part mounted to tu rn upon the lower section,braces between the lower section of the post and the post-support, a ring fitted to the upper section of the post, and braces between the said ring and the said post-support, substantially asset forth.

3. In combination, a sectional post, the lower section being fixed and the upper section mounted to turn upon the lower section about a vertical line, hoisting-rope passing through the joint between the sections of the post, and a windlass journaled to the fixed section of the post and adapted to wind up the hoisting-rope, substantially as set forth.

4. In a crane, a post, a jib having pivotal connection with the post, and braces having pivotal connection at its upper end with the jib, and an automatic clamp movable upon the post and having the lower end of the aforesaid braces pivoted thereto, substantially as set forth.

5. The herein-described wagon-body lifter comprising a base, a sectional post secured at its lower end to the base and having its upper portion mounted to turn upon the lower fixed portion, a jib pivoted to the turnable section of the post, and braces between the jib and the outer portion of the post and adjustable for varyin g the elevation of the outer end of the jib, a ring applied to the upper portion of the post, braces between the said ring and base, awindlass applied to the fixed section of the post, and a hoisting-rope passing through the joint between the sections of the post and adapted to have its lower end wind upon the windlass, substantially as specified.

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