SPECIFICATION forming part of Letters Patent No. 350,071, dated September 28,1886.

Application tiled June fl, 1556.

To all 1071 0m it may concern.-

Be it known that I, \VILLIAM. F. Monmm, a citizen of the United States of America, residing atCutchogue, in the county ol'Sul't'oll; and State of New York, have invented certain new and. useful Improvements in Lifti ng.lacks; 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 sam e, reference beinghad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this SPHlfiCiltlOll.

My invention relates to certain new and useful improvements in lifting-jacks, the object otsaid improvements being to provide aliftingjack which can be used for ordinary purposes, and also for lifting an axle, so as to hold both of the wheels elevated at the same time.

My invention consists in the construction and combination of the parts, as will be hereinafter full y set forth, and specifically pointed out in the claims.

In the accompanying drawings, which illnstrate my invention, Figure 1 is a perspective view 01' alifting-jack constructed in accordance with my improvements. Fig. 2 is a sectional view. Fig. 1'; is a detail perspective view showing the axle-lifting device removed and a modification of the cam-lever. Fig. 4 is a side view showing the axlelift-ing device applied to the lower portion of the lifting-jack; and Fig. 5 is a transverse sectional viewth rough the line a .c of Fig. i.

A refers to the stationary base, which is provided with an n wardly-pr iecting bar or bars, a, which are rigidly attached thereto. The upwardly-projecting portion a, as shown in Figs. 1 and 2, is rigidly attached to the base, and is provided with a roller, a, against which the metal-covered face a of the cam-lever B will abut.

Adjacent to the central and upwardly-projecting portion, a, side pieces, 0 O, are secured, said side pieces embracing the station ary upwardly-proiecting portion, and are secured thereto so as to slide therein by means of transverse slats c 0. The upper portions of these vertical bars 0 C are connected to each (No mode-Ll other by a transverse bar, (l, which is provided with a central wrl'oratiomthrough which a screw, it, passes for attaching the main bar of the lifting device thereto. The cam-lever 13, which is provided with a metallic face, a, is eeccntrically pivoted, by means of a trans verse bolt or pivot-pin, e, to the movable side pieces, (l (l, in such a manner that when the handle 13 of the cam-lever is depressed said ,side pieces will be elevated. The pivot c is located to one side of a vertical line with a roller, (1, so that when the lever is fully depressed it will be securely locked.

f refers to converging brace-bars, which are tionary upright portion, (I. These barsf not only serve as brace-bars, but also prevent the vertical bars 0 0 being removed from the base. as the lower strap c will limit the upward movement thereof. The upper cross-bar, may be recessed, so that a wagon axle or bar, 1! will lie within said recess.

In Fig. 3 ol" the drawings I have showu a modification of my improvements, in which case the central bar is movable between the side pieces, which are rigidly attached to the base, said central movable portion having cccentrically attached thereto a lever with a central recess, the side portions of said recess abutting against the side pieces.

I refers to a horizontal bar, which is pivota-lly attached to the upper portion of the lifting-jacl by means of the central bolt, (1, said bar having its ends slotted, as shown at E, for the reception of ratchet-bars F, the ratchetteeth thereof engaging with the pivoted dogs G, which are secured within the opposite end of the slot. The ratchet-bars F are provided at their upper ends with transverse bearingblocks which may be placed under the wagon-axle or other object which it is desired to elevate. The dogs G have downwardly so as to provide weighted handles, which will have a tendency to throwthepawls in engage ment with the ratchetbars F. \Vhen it is desired to elevate the ratchet' -bars, they may be simply moved upward, and by swinging the handles of the lock ing-dogs inwardly they will be disengaged from the ratchet-teeth, so

attached to the base A and to the central staextending portions 1 which are constructed that said oars can be readily moved downwardly. It will be noted that the bar E is pivotal] y attached to thelifting-jaek, and when the device is used for lifting wagon-axles said bars may be swung upon said liftingjaek.

In Fig. 4 I have shown the bar E applied to the lower portion of a lifting-jack, instead of the upper portion, which is sometimes desirable in holding wagon-bodies at but a slight distance above the floor when the wheels are removed, so access can beieasily had to the upper parts. \Vhen the bar E is attached to the lower portion of the lifting-jack, the same 7 may be mounted on a rolling platform.

By meansof the liftingjack herein described 1. In a wagon-jack, the combination of the movable portion, to which is pivotally attached a cam-lever, a horizontal bar, E, attached to the movable portion. of the lifting-jack and provided at its ends with slots, within which are located pivoted locking-dogs and adjustable ratchet-bars, substantially as shown, and for the purpose set forth.

2. In combination with a lifting-jack, a device for supporting Wagon-axles, consisting of a horizontal bar, vertical adjustable bars F, with ratchet-teeth, and gravity-dogs for holding said bars in place, substantially as shown, and for the purpose set-forth.

3. In combination with a liftingack constructed substantiallyas described, a horizontal. bar with vertical adjustable end pieces, said bar being attached to the lifting-jack so as to swinghorizontally,substantial]y as shown, and i for the purpose set forth.

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