JOHN L. WVILLIAMS, OF CLINTON, KENTUCKY.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 630,154, dated August 1, 1899.

Application filed March 17,1899. Serial No- 709,487. (No model.)

To all whom it may concern:

Be it known that 1, JOHN L. \VILLIAMS, a citizen of the United States, residing at Clinton, in the county of Hickman and State of Kentucky, have invented a new and useful \Vagon-Jack, of which the followingisa specification. l

The invention relates to improvements in wagon-jacks.

The object of the present invention is to improve the construction of lifting-jacks and to provide a simple, inexpensive, and efficient one adapted to be readily arranged for elevating an axle, so that a Wheel may beentirely removed, and capable of being also arranged for partially removing a wheel when it is desired simply to lubricate the axle.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective View of a wagon-jack constructed in accordance with this invention and shown arranged for partially removing the wheel. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is an elevation showing the wagon-jack arranged for engaging an axle. Fig. 4 is a detail perspective View of the slide for engaging a hub. Fig. 5 is a detail view showing the lever suspended by the outer fastening device from the pivot.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a standard provided with a longitudinal opening or bifurcation 2 and forming a guide for a vertically-movable slide 3 and adapted to receive an operating-lever 4, which may be connected with the slide, as illustrated in Figs. 1 and 2 of the accompanying drawings,to remove a wheel partially from an axle for lubricating the same, and which is also capable of being arranged to engage an axle to lift the same to permit a wheel to be entirely removed. The lower end of the standard is designed to be slightly rounded or tapered, as shown, to enable it to be tilted outwardly to draw a wheel partially off an axle, and the slide 3 is composed of a central body portion 5 and plates 6 and 7 of greater width than the slot or bifurcation, whereby the slide is mounted on the standard. The plates 6 and 7 are arranged on the front and rear faces of the standard, and the plate 6 has its upper end outwardly offset and provided with arms 8, forming a head, which presents an upper concave edge or face adapted to receive the hub of a Wheel. The lower end of the plate 6 is substantially T-shaped, and the upper end of the plate 7 is also T-shaped and is pro* vided with an eye 9, adapted to be engaged by a rod 10 of the operating-lever 4:. The rod 10, which is located near the outer end of the operating-lever, has one end hingedly connected to the same, and its other end is provided with a hook 11 to engage the eye of the slide detachably. The rod 10 at its at tached end is provided with an eye which is linked into an eye or staple of the lever.

The operating-lever is provided near its outer end with a perforation 12, adapted to receive a removable pivot 14 and capable of fulcruming the lever at different points. The pivot 14 is connected by a short chain 15 with the standard, which is provided at opposite sides with perforations 16, arranged at intervals and adapted to permit the pivot to be raised and lowered. Instead, however, of adj ustably pivoting the lever by means of a removable pin and perforations the lever may be provided with fixed pivots, and the standard may have bearing notches or recesses to receive the same.

When the pivot of the lever is arranged in the perforation 12 and the rod 10 is connected with the slide, the device is adapted for en-.

gaging the hub of a wheel, as shown in Fig. l of the accompanying drawings. The standard is then placed in front of the wheel and the head of the slide is brought beneath the hub, and the lever is then swung upward above the standard and is locked in such position by a'fastening device consisting of a substantially centrally-arranged hooked rod 17. The rod 17 has one end hinged to the lever similar to the rod 10, and its other end is provided with a-hook 18, adapted to engage one of the spokes of the wheel. After the lever is secured to the .wheel it may be used for drawing the same outward to lubricate an axle and to return the wheel to its initial position.

The hook 11 of the rod 10 is adapted to be arranged on the pivot 14 to fulcrum thelever between its ends, as illustrated in Fig. 3 of the accompanying drawings. The shorter arm of the lever is then placed beneath an axle to lift the same in the usual manner, and the lever is secured at the desired adjustment by means of the inner centrally-arranged hooked rod or fastening device 17, which is adapted to engage any one of a series of perforations 19, located at one side of the standard and forming a continuation of the series of perforations for the pivot. When the slide is not in use, it may be arranged at the bottom of the standard and will not interfere with the operation of the lever when the latter is employed for engaging an axle.

The invention has the following advantages: The lifting-jack, which is simple and comparatively inexpensive in construction, is strong and durable, and it is adapted to be quickly arranged for lifting the body of a vehicle, so that a wheel may be entirely removed or for simply partially removing a Wheel when it is desirable to lubricate an axle.

Changes in the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacri-' ficing any of the advantages of this invention.

What is claimed is 1. A device of the class described, comprising a standard,a longitudinally-movable slide mounted thereon, a hand-lever, means for fulcruming the lever at different points of its length and at intervals along the standard, and means for connecting the lever with the slide, said lever in one of its adjusted positions being projected at one end beyond the standard to engage an axle, substantially as described.

2. A device of the class described comprising a standard, a vertically-movable slide mounted on the standard, an operating-lever adapted to be fulcrumed at different points on the standard, and the inner and outer fastening devices adapted to connect the lever with the slide and with a wheel, and capable of securing the lever in an adjusted position when lifting an axle, substantially as described.

3. A device of the class described comprising a standard provided with a longitudinal opening, a slide composed of a body portion arranged in the opening, and front and rear plates arranged on the opposite faces of the standard, one of the plates being provided with a head forming a seat for the hub of a wheel, a lever adapted to be fulcru med at different points on the standard, an outer fastening device detachably engaging the slide, and an inner fastening device mounted on the lever and adapted to engage either a spoke of a wheel or the standard, substantially as and for the purpose described.

4. A device of the class described comprising a standard, a pivot, a slide mounted on the standard, a lever adapted to be f ulcrumed. on the pivot and provided with an outer fastening device, adapted to engage the slide or the said pivot, and an inner fastening device mounted on the lever and adapted to engage either aspoke of a wheel or the standard, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature i the presence of two witnesses.

JOHN L. XVILLIAMS.
