UNITED STATES PATENT OFFICE.

WESLEY C. LOUCKS AND CHARLES W. DERRICK, OF AVOCA, NEW YORK.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 373,189, dated November 15, 1887.

' Application filed September- 3, 1887. Serial No. 248,742. (No model.) I

To all whom it may concern:

Be it known that we, WESLEY C. LOUOKS and CHARLES W. DERRICK, citizens of the United States, residing at Avoca. in the county of Steuben and State of New York, have invented a new and useful Improvementin Carriage and WVagon Jacks, of which the following is a specification.

Our invention relates to improvements in carriage and wagon jacks; and it consists in certain novel features, hereinafter described and claimed;

In the accompanying drawings, which fully illustrate our invention, Figure 1 is aside ele- Vation of ourimproved jack, showing it in its lowered position; and Fig. 2 is a similar view, lOOking at the opposite side, showing it as supporting the vehicle-axle in an elevated position.

Referring to the drawings by letter, A designates the leg or standard, and Bthe liftingbar. The lifting-bar B is provided at its up per end with a series of notches, C, in which the axle of the carriage or wagon is held while being cleaned or lubricated.

D designates a brace which has one end pivotally secured to the leg and its other end pivotally secured to the lifting-bar, as clearly shown.

E designates a link havingits opposite ends pivotally secured to the upper ends of the leg A and the lifting-bar, and the operating-lever F is pivotally mounted upon the same bolts, G H, that secure the link. The operating-lever is thus pivotally secured to both the liftingbar and the standard or leg on the side opposite the link E. The standard is thus brought 'into the same plane with the lifting-bar, which is provided on its under edge, near its top,with

the notch I, and when the lever F is depressed the upper end of the standard is thrown into this notch I, as clearly shown.

The operation of the jack will, it is thought, be readily understood. When the operatinglever is elevated, as shown in Fig. 1, the standard and the lifting-bar will be drawn from each other and the lifting-barlowered. When the device is in use, the axle of the carriage or wagon is rested in one of the notches Cin the upper or outer edge of the lifting-bar, and the lever is then depressed. As the lever is forced downward, the upper end of the lifting-bar is raised, thereby lifting the wheel of the vehicle from the ground, when it can be readily removed from the axle and the same cleaned or lubricated. When the upper end of the lift ing-bar is raised, the'upper end of the standard is simultaneously thrown downward and toward the lifting-bar and into engagement with the notch I, thereby, in connection with thebrace E, firmly supporting the lifting-bar and preventing the spreading of thejack.

It will be seen that our device is very simple in construction and operation, and can be manufactured at a small cost. v

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

The improved carriage and wagon jack herein described and shown, comprising the leg or standard A, the lifting-bar B, having a series of notches, C, in its upper edge to receive the vehicle-axle, and a notch, I, in its lower edge to receive the upper end of the standard,.the link E, pivoted at its opposite ends to the lifting-bar and to the standard by means of the bolts G H, theoperating-lever F, pivotally mounted upon said bolts G H, and the braceD, having its opposite ends pivoted, respectively, to the standard and the liftingbar, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in presence'of two witnesses.
