UNITED STATES JOHN G. CRAWFORD,
PATENT OFFICE.
OF FAYETTE, IOWA.
IMPROVEMENT IN wAeoN-JAcK's.
Specification forming part of Letters Patent No. 170.062, dated November 16, 1875 application filled September 29, 1875.
To all whom it may concern:
Be it known that I, JOHN C. CRAWFORD, of Fayette, in the county of Fayette and State of Iowa, have invented a new and useful Improvement in Wagon-Jacks, of which the following is aspecification:
The present invention relates to an improvement in jacks for raising the axles of vehicles; and its nature consists in. a two-part frame, supported on a stand, and pivoted to the frame is a lever, which is provided with a metal liftin g-seat, for elevating a bar to be placed under an axle. One side of the frame is provided with a strap-stop, to prevent the lever from being lifted too high, and the top end of the two-part frame is bound with a strap of iron to hold the bar in place, as the whole is hereinafter shown and described.
In the drawings, Figure 1 is a side elevation of my improvement in wagonjacks; Fig.2, an end elevation of the same.
A represents a wooden stand, which supports a two-part frame, B B, also made of wood. 0 represents a lever, which is placed between the frame B B, and pivoted to it at H, and which is provided with a lifting seat,
Gr, made of strap-iron, and secured to the top edge of the lever and to the end of its short arm. The angle of the seat G on its upper part, with reference to the lever, is such that when the lever is elevated, as shown by dotted lines J, the end of the bar D will bear flat on it. The frame B B is provided with a metal stop, F, to hold the bar D in the frame, and prevent the lever G from being raised too high when the pin H is put in the hole I, and the top of the frame is handed at E, to hold it together and support the bar D.
To use the device, the stand A is placed on the ground, so as to bring the bar D under an axle-tree; then raise the bar by bringing down JOHN. G. CRAWFORD.
