WAGON-JACK.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed February 11, 1907- Serial No. 356,707-

To all whom it may concern:

Be it known that I, OIIARLEs STILABOWER, a citizen of the United States, residing in Nineveh township, in the county of Johnson and State of Indiana, have invented ccrtain new and useful Improvements in Wagon- Jacks; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, -which form a part of this specification.

This invention relates to lifting jacks and has reference particularly to implements that are designed to lift wagons or similar vehicles by application to the under sides of the axles near the wheels in order that the wheels may be removed for various purposes.

The object of the invention is to provide a simple and reliable lifting jack adapted to be cheaply constructed and to be durable and economical in use.

The invention consists in a wagon jack constructed in a novel manner, and in the novel parts and combinations and arrangements of parts as hereinafter particularly described and claimed.

Referring to the drawings Figure 1 is a side elevation of the improved jack in which dotted lines indicate the position of the lever when taking up or releasing the load; Fig. 2, a front elevation of the jack; Fig. 3, a horizontal sectional view of the jack taken centrally of the lever thereoi; Fig. 4, a vertical central sectional view of the jack; Fig. 5, a fragmentary sectional detail view of the lever lock of the jack; Fig. 6, a perspective view of the grip head of the lock; and, Fig. 7, a perspective view of the springs for holding the lever lock out of operative position.

Similar reference characters in the different figures of the drawings designate corresponding elements or features of construction.

In a practical embodiment of the invention the jack comprises a wooden base A having considerable length and height but relatively narrow measured horizontally, two standards B and B being bolted or otherwise secured to opposite sides of the base, the standards having asuitable number of pin holes 0 in their upper ends to receive a fulcrum pin D whereby a lever E that has a pin hole F is supported adjustably between the standards, the lever having a short end having a concave top G to support the load H, the longer end of the lever having a handle I. A screw J is inserted in the under side of the lever E at suitable distance from the fulcrum pin D and has a hook K. Alever lock comprises a rod L having an eye M connected to the hook K, the rod having a screw threaded end N on which is a grip head 0 having an aperture P to receive the rod and provided with a pair of wings Q and Q that extend laterally and have slightly sharpened edges adapted to engage the forward edges of the standards B and B. A nut R is placed on the threaded end N at the rear side of the head 0, and a thumb nut S is placed on the threaded end N at the opposite or outer side of the head O so that when the nut S is slackened the nut It may be readily turned with the fingers to adjust the head O which may then be locked by means of the nut S. A pair of spring fingers T and T are formed of spring wire integral with an eye U that receives a screw V which is inserted in the top of the lever E near the pin D and secures the fingers on the lever.

In practical use the lever E may be adjusted vertically by shifting the pin D from one pair to another pair of the pin holes O and then the grip head O should be adjusted on the rod L so that the wings Q and Q will engage the front sides of the standards B andB immediately above the base A when the lever E is approximately level. Then in order to lift an axle the rod L should be swung upwardly between the fingers T and T which will hold the rod against the under side of the lever, the latter then being swung upwardly so that the concave top G may be placed under the axle, after which by pressure on the handle I the load may readily be lifted and the rod L should then be disengaged from the fingers so as to drop onto the base A, when the han dle I may be permitted to rise slightly until the wings Q and Q engage the standards which will prevent further rise of the handle and the load will be securely held as long as it may be desired. To release the jack the handle I should be pressed down slightly, then the rod L should be thrown up so as to be caught by the fingers T and T, and then the handle may be permitted to rise further until the wagon rests on its wheel, after which the short end of the lever can be withdrawn from under the axle.

Having thus described the invention, what is claimed as new is 1. A wagon jack comprising a base, a pair of standards secured to opposite sides of the base with clear space between the standards at the extreme top's thereof and thence down to the base, a lever pivoted to the tops of the standards in the clearspace, a pair of spring fingers mounted on the lever, a rod hinged to the lever and movable into contact with the pair of spring fingers and also extending be tween the standards, and a grip head on the rod.

2. A wagon jack comprising a base, a pair of standards secured to opposite sides of the base, a lever pivoted to the standards, a pair of spring fingers mounted on the lever, a rod hinged to the lever and extending between the standards and having a threaded end, a pair of nuts on the threaded end of the rod, and a grip head between the nuts and having a pair of wings extending across the fronts of l the standards.

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

CHARLES STILABOWER.
