WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 490,017, dated January 17', 1893.

Application iiled. March l5 x 1892. Serial No. 424,990. (No model.)

To all 'whom it nea/y concern:

Beit known that l, AUGUSTIN JOHN GALIN- DO, acitizen of the United States, residing at Concord, in the county of Contra Costa and State of California, have invented a new and useful Tagen-Jack, of which the following is a specification.

rihis invention relates to wagon jacks, and consists of the construction and arrangement of parts thereof as will be hereinafter more fully described and pointed out in the claim.

The object of this invention is to provide a device of this character having a simple and eective construction and arrangement of parts easily and readily operated and handled, strong and durable, and comparatively inexpensive of manufacture.

In the drawings-Figure l is a perspective view of ajack embodying my invention, showing the parts in position for engagement. Fig. 2 is a vertical section of the device. Fig. 3 is a perspective view of a modified form of the device, showing the base-block and clips removed and at one side of the standard.

Referring to the drawings,A represents the post or standard,having 'an upper biturcated end A, with an inclined wall A2 adjacent to said bifurcated end. The said standard is also formed with a groove ce in one side thereof having overhanging anges ct and au entrance-mouth opening` or groove c2 which is formed by cutting the anges away at this point, said mouth being at the upper terminating end of the mouth o. In the upper bifurcated end A of the said post or standard is pivotally mounted a lever B, having a slotted cam-head B', the said inclined wall A2 of the said standard adjacent to the bifurcated end A thereof allowing the said lever to be closed down against the post or standard. IVithin the said slotted head B of the said lever Bis pivotally secured a lu g or extension integrally formed with an arm C, said arm C being serrated or formed with a series of steps to engage with the axle, as is common in devices of this class. From the lower end of said arm C depends an extension D which is formed with a flanged lug D', movably mounted within the groove a of the standard A, and thereby guide the said arm in its movements as it is adjusted by the lever B. This strengthens the entire construction and assists in the positive action of the several parts, allowing free movement of the said arm C in a vertical direction, but at the same time holding it in a positive movable position. The lug D can be readily inserted in the throat or opening c2 of the said groove a when the parts are assembled, or withdrawn therefrom when said parts are disassembled.

As shown in Fig. 3, the groove a is dispensed with and an eye-bolt A or analogous structure substituted therefor, the extension D in this instance being made longer and freely moving through said eye-bolt or ring D2, if such be used. The advantage and function of the device are equally Well sustained in this form as in that first described, and the use of devices of this character being readily understood,it is unnecessary to further explain the same.

The head B of the lever B is extended at a right angle, or nearly at a right angle, to the said lever, and as said lever isroperated it throws the arm C over from the standard A and makes itI convenient for engagement with the axle of a vehicle. Vhen said arm C is drawn toward the standard A by moving said lever B close against said standard, the pivotal point of said arm C is thrown past the vertical line of the pivotal point of the head B with said standard A, and the said arm is thereby sustained i-n its adj usted position, being held at its lower extended end D as hereinbet'ore set forth.

To the lower end of the standard A are secured swivel pins or rods E, and said lower end of the standard, together with the swivel pins or rods, are respectivelyr {itted in recesses F and F formed in a base-plate G. When the said swivel pins or rods have been properly located in the recesses F bearing-clips H are mounted thereove'r to secure the several parts intact and at the same time provide for a movement Aof the standard A in order to permit the same to slight] y rock to more readily accommodate setting the jack in proper position under the axle or part to be raised.

Having thus described my invention, what I claim as new is- In a lifting-jack, the, combination of a post or standard, having an upper slotted end, an operating lever mounted in said slotted end of said post or standard, and having an angu- ICO lar slotted extension or head, e serrated or stepped erm pvotally mounted in the seid slotted extension or head in advance of the fulorum or pivotal point of the latter, said serrated or stepped arm being provided with a lower extension movably connected at its free end to the said post or standard to thereby allow the said arm to have 'e vertical adjustment andlatere-l movement, swivel pins or rods connected to the lower end of the said post or standard, e bese-plate lla-ving recesses
