I WAGON JACK. 110.317.577. Patented May 12, 1885..

UNITED STATES PATENT OFFICE.

JACOB T. REED, OF RENO, NEVADA.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 317,577, dated May 12, 1885. Application filed September 19, 1884. (No model.)

To all whom it may concern:

Be it known that I, JACOB T. REED, a citizen of the United States, residing at Reno, in

the county of Washoe and State of Nevada, have invented a new and useful Wagon-Jack or Lever Lifter of Weights, more particularly adapted to raising expeditiously the axles and wheels of wagons, carriages, buggies, and other similar vehicles for purposes of cleansing and lubricating their rotary bearings, of which the following is a specification.

My invention relates to improvements in such wagon-jacks or lever lifter of weights and vehicles progressing by rotary motion, and other like weights, and sustaining them when so lifted, all by the action and construction of my jack or lever lifter, in a quick and easy manner, which is also so constructed as to shut together, when not in use, conveniently, for handling and transportation, and which also lowers the thing lifted as easily and safely as it lifts the same. I obtain these effects by the mechanism illustrated in the accompanying drawings.

Figure 1 shows the entire machine ready for use, with the lever resting in one of the slots in position to be placed under and raise the weight to be lifted bya downward pressure on the long arm of the lever above its fulcrum. Fig. 2 shows the entire machine with the lever closed between the upright bars in shape for transportation. Fig. 3 shows aside view of the base and the bars or upright pieces, which are fastened to the base and connected at the top. Fig. 4. is a view of the lever connected by a pin with an arrow or piece transmitting the force of the short arm of the lever to the part that lifts the weight to be raised. This latter part is also connected with said arrow by a ring, hinge, or pin, allowing of a rotary upward pressure, so that when thelong arm of the lever is raised to its greatest height the lower end of such arrow is on the edge of the perpendicular bars next the weight to be raised; but when the long arm of the lever is pressed down nearest to the base, the lower end of such arrow is then transported to the other side of such perpendicular bars, and is brought beyond the center of the lever -pins resting in the slots, so that the weight bears on the long arm of the lever, keeping it down and the weight raised up.

Similar letters refer to similar parts throughout the several views.

A is the base, which may be of any shape.

13 B are two perpendicular parallel bars or posts, firmly attached to the base A by bolts and nuts or screws or other device. Such bars must be of a height corresponding with the height of the wheels of the vehicle or point of contact with the weight to be raised, and must be firmly joined together at the top as well as the base, to keep them equidistant or parallel to each other. The space between such bars must be great enough to afford room for the support of the weights to be raised to slide up and down from the top of said bars to the base, and to afford room for a lever strong enough to raise any desired weight. Such bars must be of suffioient dimensions and strength to allow slots or rests to be constructed in their edges on the side upon which the long arm of the lever is to be operated, such slots to be made along about the middle, onethird of the length or height of such perpendicular bars, which is done to accommodate the lifting power of the lever to different heights of axles and weights.

0 is a lever with its long arm straight and its short arm curved upward, having a pin through it or cast on, each of its sides, to fit in the slots or rests on the perpendicular bars, so that, thus raised and supported, the pins in the slots form a fulcrum of sufficient strength to uphold anyweight desired to be raised. The lower end of the short arm of the lever may be cleft in twain or divided in its thickness at the end, so as to admit the lower endof the arrow ortransmitter of the leverpower in such cleft space, and a pin or bolt put through, connecting the short arm of the lever with the lower end of the arrow loose as to such arrow, so it can revolve about said pin. Such lever is to be made of such length that when the end of the short arm rests on the base A, between the upright bars, the other end of the lever will be as high as the lower edge of the block or piece that holds-the upright bars in'place at their upper ends, or nearly so, in order that the upper end of the long arm of the lever may shut in between such bars, so as to be handy to carry or be transported, and may be kept in such position by a button or similar device attached to the upper end of said bars.

D is a shaft, arrow, or piece connected with 'the end of the short arm of the lever by apin,

ring, or hinge, so as to allow of a rotary or similar motion, and also connected with the part that slides up and down between the upright bars and'protrudes therefrom on the side opposite the long arm of the lever as a support or lifter cf the weight to be lifted. Such connection with the lifter last aforesaid is also to be made byapin, ring,or hinge, allowing also of a rotary or similar motion to such shaft or arrow atsuch point. Such arrow or shaft is to be made sufficiently long to give the height or length of lift desired to the weightto belifted, and is to be of such dimensions and strength as to easily play in the space between the perpendicular bars B B, and still be strong enough to raise any weight that may be de sired.

E is the lifter last above specified, or means of raising and sustaining the thing lifted. It is to fit in between the bars B B, so as to slide up and down between them, and be held between them firmly by flanges extending outwardly the thickness of such bars B B. On the edge of said bars B B opposite the long arm of lever C said lifter E extends out from between said bars B B a sufficient length to form a rest for the thing to be lifted whereby and whereon to lift the same, and is to be connected by a pin, ring, or hinge, making a revolving or movable connection with the shaft wagon jacks.

D, and by it to the lever O, so that O, D, and E can be placed between the upright bars B B and slide up or down the same, as desired; and when the pin 0 in lever C is placed in the slots in bars B B it forms a lever ready for use, or, when closed, as in Fig. 2, ready for transportation.

This jack may be made of either wood or any suitable metal, and the materials may be made lighter or heavier, according to or in proportion to the weight to be raised; but for heavily-loaded wagons or other great weights the several parts will be made of east or mal leable iron, except the base may be made of wood. Such machine is more particularly intended to raise buggies, carriages, wagons, and like vehicles that require for all ordinary purposes but a short lift.

I am aware that the lever-power in some form has been used in the construction of I therefore do not claim as my invention the lever-power; but

What I do claim as myinvention, and desire to secure by Letters Patent, is

In a lifting-jack, the combination of notched bars B B, end-bent Fever 0, carrying a movable fulcrum, and the lifter E, pivoted to the end of said lever, all adapted to co-operate as and for the purpose specified.
