"IMPROVED CARRIAGE-JACK -wm The Schedule referred to :ln theme Letters Patent and making part of the same.v

To all persons .to whom these presents may come; Be it known that I, 'CALVIN H. PAINE, of the city and county of Providence, and State of Rhode Island, have invented an Improved.V Carriage-Jack; and I do hereby declare the same to be fully described in the following specification, and represented `in the accompanying drawings', of which- Figure 1 denotes a side elevation,

Figure 2, a front-edge elevation, and

Figure 3, a vertical section of it.

In such drawings* A denotes a standard or dat post, erected on a baseboard, B.

Against the front face of' this post is a flat bar, C, having its uppery end scarl'ed, and providedV with a series of righteangular notches, a a a. There is also in the frontY edge of the bar C, a series of holes or mortises, b b' 1, &c., for reception of a pin, c, connected with-.the bar by a chain, D.

The bar C is held in connection with the standard.

A by means of screws or bolts e c, which screw in'to the balyand go through slots ff, formed vertically in the standard, the samebeing in order to allow of the bar being moved vertically relatively to the standard.

Within the lower Apart of the inner face of the standard A, is a chamber, or recess, g, which, formed as represented in g.3, is intended to receive a toggle, D,

which, at its lower part, is fastened to the standard,

as shown at h.

The toggle, at its upper part, is pivoted or jointed by a pin, m', to one angle of one end of'a metallic leverfplate, E, formed as represented. This plate extends into 'a chamber, or recess, t', formed in the inner face of the bar. C, in manner as shown in Figures 4 and 5, one of which is a rear-edge view, and the other, 'an inner-side View of the said bar.

'At `the vother corner of vits front end, the metallic lever-plate E is pivoted to the' bar C, the connectingpin being shown at 'la Furthermore, to-the plate E, a lever, or-handle, F,

is atlxed, it being arrangedwith the plate inmanner as represented.

l The lever-screw e constitutes plate E, which, when depressed, brings up against the the three joint-pins, Ah, m, and la, will be in or about in a straight line with each other, or the` middle one be thrown a little forward, and in advance of the others.

When thebar C is at its lowest position, the handle F will be raised up into or nearly ltion. Under these circumstances, by'laying hold and depressing the handle, the plate E and toggle will be made to operate as toggles, to elevate the bar C. V

In using `the jack, the pin'c, or some one` of the notches a aia, when the lever is in its highest position should 4be placed 4 underneath the axle of a cara stop` for. the lever' into a vertical posiriage to be raised. This having been done, it is only necessary to depress the handle F, in order to cause the bar B to rise and elevate the axle, so as to raise the wheel o" the ground;

My present carriage-jack resembles, in some relspects, that described in Letters Patent, No. 73,992,

dated February 4, 1 868, and' granted to myself, and George S. Thompson, as assignees-of myself the inventor; but in my present jack, the toggle is arranged directly between the standard and the movable bar, and in a chamber made in the standard, and thereby is better protected from injury.

That part of the lever-plate E, which constitutes the second toggle,'is also arranged directly between and covered on opposite sides, by the standard and bar. The new arrangement of parts makes a much bet- 'ter jack, both for -use and durability.

I am aware of the carriag -jack which constitutes the subject of the patent, No. 38,936, granted, June 23, 1863, to Nathan Bagley. This jack, although in some respectsv analogous to mine, di'iiers from it in several particulars. In the rst place, it has two posts or standards, between which the movable or lifterbar and theoperating-lever and toggle are arranged, whereas, in my jack, I have but one standard, A, Athe movable or lifterhar CV being arranged directly against one side of such standard, and the chambers t and g are formed within the bar and. standard, one chamber being in the bar, and the other in the standard. N o such arrangement of a single standard, ,lifter-bar, and chambers,

is shown in Bagleys carriageja'ck. In my jack, the toggle D and the lever E are arranged between the standard A and the lifter-bar C, but such-isf-not the case in Bagleysjack, in which the lever and toggle'are arranged underneath thelifterbar, and between the two standards. Thus, vwith my improvement, I dispense with one standard, andthus am-enabled not only to cheapenthe construction of the jack, but to make it thinner, lighter, and easier to handle.

I' therefore claim, as my invention, my improved jack, made as described, that is, with its toggle D andv lever-E arranged` between, and so as to be covered by the standard A and the movable bar 1C, and to operate in chambers or recesses g i, arranged in the standard and bar, fied.

I also claim the arrangement of the lower connection c, of the standard A, and the movable bar C, with the toggle D and the lever E, so asto constitute a stop, to arrest the latter, when in its lowest position, as described. I t
