WAGON-JACK.
Specification of Letters Patent.
Patented Feb. 12, 1907.
Application filed October 14, 1905. Serial No. 282,851.
To all whom it may concern.-
Be it known that I, ISAAC SHUPE, of Newmarket, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Wagon- Jacks; and I hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to a wagon-jack comprising a lifting-lever having a handle portion, an axle-sr-pporting rack connected to one side of the lifting-lever, a brace pivotally connected to the lifting-lever intermediate its ends and arranged to swing beyond the side of the lifting-lever opposite to said rack, and a stop to limit the outward movement of the brace, as hereinafter more fully set forth, and more particularly pointed out in the claims.
For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which- Figure 1 is a side view of the wagon-jack with the brace closed against the lifting-lever. Fig. 2 is a similar view to Fig. 1 looking at it from the opposite side. Fig. 3 is an end view with the parts in the same position as in Figs. 1 and 2. Fig. 4 is a side view with the brace extended and the lifting-lever in a slanting position. Fig. 5 is a perspective view of the rack, and Fig. 6 is a perspective view of the stop.
Like letters of reference refer to like parts throughout the specification and drawings.
The lifting-jack consists of a lifting-lever a, having a handle portion 1) to facilitate its manipulation, a supporting-rack c, intermediate the ends of the lifting-lever a, having steps 0 for axles of various heights, and a brace e, pivoted to the lifting-lever to support it in its operative position. The rack 0 consists of a unitary casting composed of a series of steps 0, a connecting-piece 0, uniting the steps a, and two rearwardly-projecting pins (1, which enter corresponding holes in the lifting-lever a to detachably fasten the rack to the lifting-lever. The brace e is pivoted to the lifting-lever a intermediate its ends, so as to swing beyond the side of the latter opposite to the rack c, the outward movement of the brace being arrested by a stop f, connected to the lifting-lever contiguous to the pivot g, from which the brace articulates and which engages the brace when in its operative position.
In the use of the invention the lifting-lever is placed in a slanting position beneath the axle of the vehicle, so that one of the steps 0 can engage the under side of the axle and raise it as the lifting-lever moves toward a perpendicular position, the brace 6 being in an open position, as shown in Fig. 4, to maintain the inclination of the lifting-lever with its load.
A wagon-jack as above described can be easily and cheaply manufactured and conveniently transported from place to place.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A wagon-jack comprising a lifting-lever, a supporting-rack connected to one side thereof, consisting of a unitary casting composed of a series of steps, a connecting-piece uniting the steps, and rearwardly-projecting pins to enter corresponding holes in the lifting-lever to detachably fasten the rack there to, a brace pivotally connected to the liftinglever and a stop connected to the lifting-lever, to engage and hold the brace in its operative position.
2. A wagon-jack comprising a lifting-lever, a supporting-rack connected to one side thereof consisting of a unitary casting composed of a series of steps, a connecting-piece uniting the steps, and pins projecting rearwardly from the connecting-piece and contained in corresponding holes in the liftingle ver detachably fastening the rack thereto, a brace pivotally connected at one end to the lifting-lever intermediate the ends of the latter, and a stop consisting of an angularlybent piece of metal comprising-two arms one of which is securely fastened to the lifting lever and the other projects into the path of the rearward extension of the brace to engage it when extended to enable it to rigidly brace the lifting-lever.
