' 4 Wagon JACKIE To allcohomz't'mciy concern." l

Be it known that I, Winnin HENRY GROUT,

a'citize'nof the United States, residing at Conway, Arkansas, have invented new and useful Improvements in a Wagon Jack, of which the following is a specification.

This invention relates toimprovements in wagon jacks. p i

' The foremost object of the invention is to provide a wagon jack which'embodies the elements of strength and" lightness and which insures quick manipulation and thorough reliability.

A further object is to provide a jack wherein a lever is so arranged that the mimmum amount of energy 18 required to raise the wagon to the desiredheight and which my invention in its preferred embodiment and as engaged with a wagon prior to raising the latter to the desired height. a

Fig. 2 is a view in side elevation showing my invention after the wagon has been raised and the supporting standard has autoy matically moved into an operative position.

My invention, in its preferred embodiment, consists of a main operating lever-10 which may be constructed of any suitable or desirable material. A standard llforming a fulcrum, a main supporting standard 12 and a guide rod 13 for the supporting standard 1 i The standard 11 is'preferably pivotally connected to the lever 10 and a point beyond the center of said lever, as atlt so that the desired leverage can be obtained. The

standard 12 is also pivotally connected to the lever 10 adjacent to one'end of the latter as at 15 so that it will be approximately v directly beneath its the wagon. I

The guide rod 12 is pivotally connected point of contact with at one end of thestandard 12 as at 16 and its other end passes through an eye 17 which is carried by the lever 10, the said guide rod carrying a stud 18 to engage the eye 17 and thus limit'movement of the standard 12 against the tension of'a spring 19' which pg Specification of Letters'Patent. Patented A pl'. Application filed July is,

1 92c. Serial No; "396,816. 1

is connected at one end to the lever 10 as at 20 and at its other end to the standard 12' as at 21. :From this construction it will :be observed that while the} standard 12is" permitted to fold backwardly toward the standard 11 intoaposition; such as shownin Fig. '1:its movement inflthe opposite directio'n' 'beyond a point'at-right angleto the lever 10'is effectually prevented; The spring tion at right anglesto the lever lo.

1 9 "tends to retain the standard 12 in a posicarries. the standard 12- maybe equipped Fi res 1 and 2. I

n operation the standard 11 is engaged with the ground and the adjacentend is slipped under the axle of the wagon as shown at Figure 1 which of course brings the opposite end'of the lever into. an elevated position and causes the standard 12 to be folded backwardly into the position shown. As pressure is applied to the free end of the lever'and the opposite end is elevated thespring 19 causesthe standard 12 to be moved toward its normalposition.

When the standard 12 reaches itsnormal;

position pressure on the free end of the lever 10 may be removed and the standard "10 will effectually support the wagon in its a elevated position, the standard 11 still ingas the fulcrum for the 1ever.;

In view of the different types ofwagons it'is deemed advisable to make both stand-' ards adjustable. While I do not wish to with an engaging block 22 asshown in both In order to facilitate itsengagement with it the wagon the end of the lever 10 which V 7,

limit myself to any particularf form of ad I justment I have shown the standards in this I instance provided with openings 23 .so that necessary.

Having thus fully. described my invention} desire to secure 1. In a wagonjack an operating lever what I claim as. new and by Letters Patent is:

having a load-bearin end and ahandle-end,

second supporting standard '"pivota yv con i In the foregoing it is believed that the adff l r vantages and novel features ofmy invention J will be 'readily understood and therefore further detailed description is deemed on;

a supporting standar pivotally connected to said leveradjacent theIOad-bearin end, a

ring end, means to limit thepivotal move:

I I the. lever 10 can be raised or lowered should. occasion so require.

nected to said lever beneath the load;bearment of the second standard in one direction with respect to said lever, and tensionable means yieldingly resisting movement of said second standard in an opposite direction, said tensionable means normally tending to hold the second standard in supporting position beneath the load-bearing end of the lever, and a load receiving block mounted at one end of the lever and in line with the second standard thereof.

2. A wagon jack comprising a main 0per ating lever having a load-bearing end and a handle-end, a supporting standard pivotally supporting the lever adjacent the loadbearing end, a swinging support standard pivotally connected to the lever in line with the load-bearing end, means for tensionably connecting the swinging standard to the lever and serving to retain the former in supporting position beneath the latter, a

guide rod having one end pivoted to the support standard and a handle-end slidable across the lever, an eye-member mounted on the lever for embracing the handle-end of WILLIE HENRY GROUT.
