WAGON-JAC K.

SPECIFICATION forming part of Letters Patent No. 436,594, dated September 16, 1890.

Application filed March 3. 1390. Serial No. 342,454. (No model.)

To all whom t may concern:

Be it known that we, ALEXANDER T. BRANN and AUGUSTUS W. BRANN, both citizens of the United States, and residents ot Dayton, in the county of Lyon and State of Nevada, have jointly invented a new and useful Improvement in Wagon-Jacks.

Our invention relates to improvements in wagon-jacks, in which the leverage for lifting the axle is applied above the axle at such an elevation that no stooping is required, as will be more fully explained.

Figure 1 is a perspective View showing the catch-block partly raised; Fig. 2, an elevation showing the catch-block raised a little more than in Fig. 1. Fig. 3 is an elevation showing the catch-block fully raised up and Fig. 4 is an elevation showing the jack in the position of holding the Wagon-Wheel clear of the ground, a part of the wheel being broken out.

A represents the standard or main upright frame of the jack; B, the base or foot of the jack; C, the grease cup or holder; D, the slideblock, which is stepped or notched in its opposite sides; E, the catch-notches or steps; F, the guide-slot; G, the guide-bolts; H, the wrench-hook; I, the angular operating-lever, which is fulcrumed at its angular point to the standard; J, the connecting and lifting rod; K, the stop-pin for the operating-lever; L, the wrench; M, the pivot of the operatinglever, and N the axle of the wagon.

The following is the construction of our improved Wagonjack carrying the Wrenchholder and grease-cup and the manner in which they are combined, arranged, and operated. The upright frame or standard A is generally formed of Wood, although metal may be used in the construction of the same, and other forms of guides may be employed for allowing the catch-block D to slide up and down upon the same without changing the nature of the invention, and the lever I and connecting-rod .I maybe connected and operthe Wheel free from the ground, so that it may be taken off and greased. The lever I stops against the stop-pin K. The upper end of the lever has then passed over the fulcrum vertically and so far over as to throw the weight and pressure against the stop-pin K, which will retain the lever in that position b v reason of the weight upon the slide-block, as .will be seen by reference to Fig. 4. As the handle I is brought down, the rod .I is drawn up, raising the axle N, which is upon one of the notches or steps E of the catch-block. This operation is performed Without stooping down. The grease for the spindle is taken from the grease-holder C. The axle is let down by raising the handle of the lever I. The nut is then replaced and tightened by means of the Wrench L, which hangs upon the holder H. n

Having described our invention, what We claim is- In a lifting-jack, the combination of the standard A, having the slots F F, the pin K, the catch-block D, having the steps E and adapted to slide on said standard by means of the bolts G on the block passing through the slots in the standard, and With the bent lifting-lever I, fulcrumed on the upper portion of the standard and made as described, with the inner end connected to the block by means of the rod J, and with the outer or handle end arranged to be lowered into contact with the pin, whereby the block is held in its raised position, as set forth.
