Description
NME
HORACE OULVER, OF RIOHFIELD, OHIO.
IM PROVED LI FTlNG-JAC K.
Specification forming part of Letters Patent No. 51,@07, dated January 2, 1866.
To all whom it may concern:
Be it known that I, HORACE CULvER,-of Richfield, in the county of Summit and State of Ohio, have invented a new and Improved Lifting-Jack, and 1 do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a side elevation ot' my lifting jack, showing its application. Fig. 2 is a plan or top View.
Similar letters of reference indicate like parts.
My invention consists in the combination ot' certain parts to constitute a lifting-jack which shall be simple, cheap, and durable, and which can be regulated and used readily and with facility.
To enable others to.. understand my invention, I will proceed to describe it.
A represents the bed-piece or sill, which is to rest upon the ground or door.
B is a standard, which is pivoted to the bedpiece, as shown at a in both figures. To the other end of this standard the lifting-lever O is pivoted, as shown at b, Fig. 1.
D is a prop, which is pivoted to the standard B just between the lifting-lever, as shown at c, Fig. 1. This prop has its lower end sharpened so that it will catch against one of a series ot' teeth, d, cut on the upper surface of the bed-piece A.
E is the locking-lever, and its lower end is pivoted to the bed-piece A, as shown at e, Fig. 1. On one side of the lever E there are made three (more or less) noses or catches, f, each nose being suitable for catching against one of a series of'teeth, g, made on the upper surcatches against the proper tooth and holds the lifting-lever up against the axle. Now the locking-lever is brought, with its appropriate nose or catch, (which is regulated by the height from the ground of the axle to be raised,) over the teeth f of the lifting-lever. The wheel is then raised by pressing down the lifting-lever, and the lifting-lever is locked iu the proper position by the nose or -catch in the lockinglever resting against the appropriate tooth f on the lifting-lever. v
It will be noticed that thisrjack can be used readily for large or small wheeled vehicles, and it possesses the advantage of being very simple in construction and cheap. It has no parts which can get out of order, and, asa whole, it is a very handy and durable jack.
What l claim as new, and desire to secure by Letters Patent, is-
The combination and arrangement of the bed-piece A, standard B, prop D, lifting-lever O, and locking-bar E, substantially as shown and described.
HORACE OULVER.
