AUTOMOBILE men;

Application filed June 11, 1921. Serial No. 476,861;

To all whom it may concern:

Be it known that I, EDWIN A. Hown, a citizen of the United States, residing at Bancroft, in the county of Kossuth, State of Iowa, have invented certain new and useful Improvements in Automobile Jacks; andI do hereby declare thefollowing 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.

This invention relates to new and useful improvements in jacks and particularly to jacks for raising automobiles and other vehicles.

One object of the invention is to provide a jack having efficient supporting means for the working end of the lever of the jack.

Another object is to provide a jack in which the base has a series of steps on which is arranged to be engaged a supportlng member carried by the lifting lever, so that the vehicle may be supported at difierent heights from the ground.

Other objects and advantages will be apparent from the following descriptionwhen taken in connection with the accompanying drawing.

In the drawing:

v Figure 1 is a side elevation of a jack made in accordance with the invention.

Figure 2 is a front elevation of the same.

Referring particularly to the accompanying drawing 10 represents a base block which may be formed of wood, metal, or-

other desired material, and formed on the upper face of the block are the steps 11.

Resting on the lowermost step 11, and extending vertically therefrom, is the post or standard 12, the same including the vertical parallel side strips 18 which are secured to *the opposite side faces of the block and the 17 bolted or riveted to the central bar. The pivot pin 15 is disposed transversely through;

the bar or lever 16, as shown. To the outer or working end of the lever 16 are pivotally I connected the depending links 18, and sei cured between the lower ends of these links is'a block 19 which is adaptedto rest on the upper face of any one of the steps 11 of the base block 10. Connectedto the upper face of the lowermost step 11 and the adjacent vertical face of thestandard 12, is an inchned brace 20. The outer end portions of the strips 17, have the upwardly extending perforated ears 21 between which is dis posed one end of an-extension lever 22, the

same being pivotally connected to the lever 16 by the pivot pin 23, which is disposed through the said ears and the lever 22.

7 While I have shown the'jack as composed of wood and metal, I wish it understood that I may construct the entire jack from metal or wood, Without departing from the spirit of the invention or the scope of the claim.

It will readily be understood from the drawing that the block 19 andlinks 18 are to be lifted, and that'upon pressingdown on the other end of the lever16, the axle will be raised. The links 18 and block 19 will then swing away from the standardand be disposed over one or another of the steps, so that upon permitting the'lever 16 face of one of the steps and thus support the vehicle above the ground or floor at the to rock downwardly under the weight ofthe l vehicle, the block 19 will rest upon the upper.

I desired elevation. By permitting the block 19- to rest on one or another of the steps 11,

the elevation .of the vehicle can beregulated.

1 Shouldgreater leverage be desired to lift 1 the vehicle, the auxlliary or extension lever 22 is swung outwardly sothatit will rest on the lever 16, outwardlyof the pivot 23.

This adds greatlyto thelength of the lever 16, thus permitting the operator to raise. a

vehicle of great Weight with lessenergy than would bepossible were the used. I

What is claimed is: a I A jack comprising a base block having its lever 16, alone,

upper face formed with a longitudinal series of steps, a standarderected on the lowermost of the steps, a lifting lever pivotally supported on the upper end of the standard, a pivotally mounted extension lever mounted on the lifting lever, depending links pivotally supported on the Working end of the lifting lever, and a block carried by the lower ends of the links for engagement on the upper face of one or another of the steps to support the Working lever at different elevations.

In testimony whereof, I afiix my signature, in the presence of two Witnesses.

EDWIN A. HOWE.
