WAGON-JAG K.
SPECIFICATION forming part of Letters Patent No. 400,109, dated March 26, 1889.
Application filed July '7, 1887- Serial No. 243,689. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM R. MOORE, of Unionville, in the county of Chester and State of Pennsylvania, have invented a new and useful Improvement i n Wagon-Jacks, of which the following is a specification.
My invention relates to an improvement in lifting-jacks; and it consists in the peculiar construction and combination of devices that will be more fully set fort-h hereinafter, and particularly pointed out in the claim.
The object of my invention is to provide a very light, cheap, and simple device, wherein the said link will act in a novel and effective manner to support the lever and permit the same to be adjusted easily and quickly, and also to permit the lever to be removed from or adjusted upon the standard, if desired.
In the accompanying drawings, Figure 1 is a perspective of a jack showing the lever pivoted securely to the upper end of the standard. Fig. 2 is a side elevation of a modification of my jack, showing means for adjusting the lever vertically.
My device, as shown in Fig. 1, consists of a double standard formed of two uprights, A A, bolted at their lower ends to the outer sides of a base, B. A hand-lever, O, is held between the upper ends of the standards A A by a pivot-bolt, D, which also holds the upper ends of the standards securely together. A loop, E, of flexible wire or sheet metal, has an enlarged end, 6, to completely embrace the standards A A, and is drawn together at its opposite end and connected by a staple or eye, a, at or near the handle end of the lever O. The loop E is made of a single piece of metal linked together at 6 and is cheap, simple, and effective in operation in connection with the smooth unnotched sides and edges of the standard. The loop is connected to the under side of the lever-handle, and may be lifted by the fingers when the lever is adjusted. When the fingers release the loop, the free end thereof will drop down upon the standard and will surround and closely embrace the same when the hand is removed from the handle of the lever and the weight of the load comes upon the heel end thereof, thus holding it securely in any adjusted position.
The jack may be easily carried about from place to place, and may be handled and manipulated entirely with one hand. It is made entirely of wood, excepting the pins and metal wire loop.
In the modification shown in Fig. 2 the upper ends of the uprights A A are securely bolted to a piece, a, and the upper ends of the standards are made with. a notch or a series of notches, a, into which the pivot-pin may be placed for adjusting said pivot upon the standards to suit axles of different heights and for completely removing the lever from the standard when desired. This can be readily accomplished, as the loop E embraces the entire body of the standard, and the stand- 7 ard may be shifted entirely through the loop.
I am aware that jacks have been constructed with a standard, a lever pivoted to the upper end thereof, and a link connecting the handle end, of the lever with the standard, and do not broadly claim such device.
I claim as my invention and desire to secure by Letters Patent In a wagon-jack of the character described, a standard having a lifting-lever, the longer arm of which has an eye or staple secured at the end thereof, through which a metal loop passes, one end of said loop being prolonged to form a stirrup and terminating in a hook which engages a similar hook on the shorter end of the loop for binding the stirrup against the standard, substantially as described.
