' Leim Patent No. 69,810, dans ocmw-15, 1867.

IMPRovsD WAGON-JACK.

T O- ALL WH'oM/IT MAY CONCERN;v l v Be it known that I, JOHN HUNT, Jr., oiIWest Hampton township, in' the county-of Burlington, and State of New Jersey, have invented a new and improved Ingen-Jack; and I derlrercbydeclare that the following .is n. full, clear, and exact description oflthe same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists of'a lifting-jack for wagons, carriages, etc'., the lever ot' which being of the second order, where the power and weight act on the 'saine side ofthe fulcrum. The. lower extremity or halt' of the prop is notched, and reduced-in size to take into the split or vforked end of the lever. A hinged support carries tbc-prop whenin use, substantially as is hereinafter shown and described. 0n reference to the accompanying drawing, making part of this specification- Figure 1 is a sidel `elevation sectioned, showing the lever A', prop B, and the lever-support C.

Figure 2 is an edge view of the prop B, and a section of the lever A throughits fork, and

Figure 3 is an edge view. i

Similar letters refer to similar partsin the several views.

lMy wagon-jack consists of a box, A, of two fiat sides, separated at the edges by thin strips, the front edge being partly open to admit the lever A', which passes through and has its fulcruxn at b. It is forked from near its middle to its back end to take i-n the reduced part cof the Vertical ratchet-prop B. Its indentations bearing against and supported byl the pin d ofthe lever A, it will be readily seen that the least vibration ofthe lever A causes the prop B to riseandnfallvith its load. When the top oi' the prop is too high to place under the axle of a wagon it can be released from the pin CZ and lowered by simply pressing it forward against the box, thereby converting it into a lever, and releasing the ratchet from the pin. To properly support and carry the lever when loaded, instead ofthe usual appliances at the end of the lever, I employ a hinged support, C, which has an opening, c, corresponding to the end ofthe lever over which it takes and carries it. The end of the lever is bevelled, corresponding to the lower edge ofthe opening inthe supportC, which is also bevelled, causing the support to ily open when the end of the lever is pressed down on the opening.

What I claim as Iny invention, and desire 'to secure by Letters Patent, is,

The box A, hinged plate G, lever A', and the ratchet-prop B, substantially as and for the purposeherein shown and described.

In testimony whercot` I hereunto sign my name to this specificationin presence of two subscribing witnesses.

JOHN HUNT, JB.
