' WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 233,779, dated October 26, 1880.

v Application filed September 21, 1880. (No model.)

To all whom t't may concern:

Be it known that I, GEORGE LEHMAN, a citizen of the United States, residing at Philadelphia city,inthe county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements inlVagon-Jacks; and I do hereby declare the following 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in the class of wagon-jacks; and it consists in combining with a j ack for raising the axle of a wagon, a grease-pot and a nut-wrench; also, in certain details of construction hereinafter more fully described and shown.

Its object is a jack that may be compactly closed for transportation beneath the seat or other convenient place within a wagon, and with which the nut may be removed and replaced and the axle raised and greased.

In the drawings, Figure 1 is a front elevation of my device, showing the handle, within which is the grease-reservoir, partly in section. Fig. 2 is a side elevation, representing the jack when closed for transportation. Figs. 3, 4, and 5 are detail views of the parts composing the nut-wrench, of which Fig. 3 is a plan view of the slotted plate carrying the movable jaw. Fig. 4 is both a side and end elevation of the movable jaw and screw-socket. Fig. 5 represents the mode of inserting the movable jaw in the slotted plate. Fig. 6 is a side elevation of the jack opened in position for use.

A is the main leg or standard, which is constructed of wood,except the top portion, consisting of the handle D, ratchet G, and jaw k, which is preferably of iron or other suitable metal.

B is the shorter standard orfulerum, and is pivoted to the main standard by a link or hinge, Gr,.connecting its top with the main standard at a point in rear of the ratchet part 0.

Fis an adjustable connecting-rod, pivoted to the main standard at a point below the ratchet by the bolt f passing through its end, and is provided with teeth 9 on its edge for engaging with a hook on the side of standard B. It is designed to hold the jack in position and prevent the legs from spreading apart when adjusted to any desired angle.

0 is the ratchet, which consists of shoulders or notches on the side of main standard A, upon which the axle rests when the jack is in position to be 0 erated.

D is the hand e, which is made hollow, the reservoir therein forming the grease-pot. The top of this reservoir is closed with a tight-titting removable cap, (I, having a stem extending down into the greusepot, on the end of which is a sponge or brush for taking up the grease.

E is the nut-wrench, which is adjustable to any sized nut, and consists of the fixed or stationary jaw is, composed of a projecting flange or lip from the lower end of the iron portion of standard A, the movable jaw it, screw 19, screw-socket l, thumb-nut r, and slotted plate H. This wrench is secured to the side of the main standard A by screws, as shown in Fig. 1, after first uniting its parts by inserting the T-shaped projection m n, 011 the under side of the movable jaw through the slot t, to accomplish which the screw-socket lot the movable j'aw must be in a direction at right angles with the slot, as shown in Fig. 5. The screwsocket is then turned to its position on a line with the slot, and the flanges a project beneath the plate on each side of the slot and confine the jaw to its place. The screw p is then placed in position and inserted into socket l, to accomplish which the jaw 70 must project slightly beyond the end of plate H. The jaw is then drawn back by the screw and the whole secured to its place on standard A, as before described, a recess being provided in the standard beneath the plate to accommodate the projection m n and allow it to move freely back and forth through the slot when the wrench is adjusted.

When not in use my device is compactly closed and secured by a hook, b, (shown by dotted lines in Fig. 2,) the adj usting-rod F bein g confined in place by a hook or button and the cap d of grease-pot screwed down.

When it is desired to grease a wagon the wrench E is adjusted to fit the nut, which is then removed from the axle. The hook bis then disengaged, and the legs A B are spread apart to the desired limit and confined in position by the connecting-rod F, which is released and swung into position, so that its teeth will engage with the hook or projection on leg B. The jack is then placed beneath the axle, so that the latter will rest upon one of the projections or shoulders of the ratchet G, and the short leg or fulcrum B is closed or brought up toward leg A in the direction indicated by the arrow in Fig. 6 until the axle is elevated sufficiently to allow of the removal of the wheel, and held in place by the connecting-rod F. The cap (I in the top of the handle is then removed and the grease applied to the axle by the sponge or brush on the end of stem a, after which the wheel is replaced and the jack closed up and stowed away in the place provided for it.

I do not limit my construction to placing the oil-receptacle in the handle, as it is obvious that it may be conveniently placed in any part of either standard. The wrench may also be attached to either.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A portable wagon-jack composed of two legs or standards pivoted together, one of which is notched to support the axle, and either provided with a receptacle for oil or other lubricatin g substance, substantially as described.

2. A portable wagon-jack consisting of two legs or standards pivoted together, one of which is provided with supporting shoulders or notches, and either one with an adjustable wrench, substantially as described.

3. A wagon-jack composed of two legs or standards pivoted together, one of which is provided with supporting-shoulders and an adjustable wrench, and one with an oil-receptacle, substantially as described.

4. A wagon-jack composed of two legs or standards pivoted together, one of which is provided with supporting-shoulders and an adjustable Wrench, and one with an oil-receptacle, in combination with an adjustable connecting-rod, substantially as described.

5. In a wagon-jack, the combination of two pivoted legs, one of which is provided with supporting-notches and with the oil-receptacle, as described, with an adjustable wrench, consisting of a screw, 1;, thumb-nut r, stationary jaw k, forming a part of the standard, and movable jaw k, secured to a removable socket, l, sliding in the slotted plate H, attached to one of the legs of the jack, substantially as described, and for the purpose set forth.

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

GEORGE LEHMAN.
