tion.

My invention relates to improvements in lifting-jacks for buggies, carriages, and all vehicles of the kind.

The objects of my invention are, first, to get a convenient lifting leverage whose use will require no more room than that upon which the vehicle stands; second, to have an automatic lock or fastening, so that the painter may use it and operate it entirely with one hand; third, that the person using it need not stoop at all; fourth, to produce an article so simple in construct-ion and use and so cheap in price that it will be within the grasp and means of every one. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 represents the jack in position for placing it under the vehicle. Fig. 2 represents it in use under the vehicle. Fig. 3 represents it in position to be removed from the vehicle.

Similar figures and letters refer to similar parts throughout the several views.

A represents the main lever, which raises the wheel; B, the leg or prop,which swings freely on the bolt which attaches it to A; O, the notches which catch under the axle; D, the hand-hold; E, the small lever which is man- (No model.)

aged by the fingers of the hand which grasps D; F, the rod which connects E wit-h B, and G the ground.

To use it, take by the handle D with one hand and clasp E with the fingers of the same hand, bringing it toward D; then throw the lower end well under the axle, so that one of the notches O catch under it. It will then have the position as represented in Fig. 1. Always stand behind the jack, then push D from you or toward the vehicle, loosening E; B will move from the inclined position shown in Fig. 1 to a substantially perpendicular position, as shown in Fig. 2, by which the vehicle will be raised. To remove, grasp D, clasping E with fingers of same hand, drawing E toward D. This will raise B and give it the position shown in Fig. 3, when 1) may be drawn toward you, the vehicle lowered, and the jack removed.

I am aware that prior to my invention lifting-jacks have been made with a bearing-down leverage.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the two beams A and B, attached by a bolt near 0, and both con trolled with one hand, at D, by means of the connecting-rod F and the small lever E, which combination afiords lifting leverage, and automatic lock or fastening, as set forth.
