BUGGY-WRE NCH- SPECIFICATION formingpart of Letters Patent No. 776,412, dated November 29, 1904. 7 Application fil d March 3, 1904. Serial No. 196,368- (No model.)

To M6 whom it may concern:

Be it known that 1, WILLIAM S. Mrr'rs, a citizen of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Improvements in Buggy-Wvrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

This invention is a Wrench for usein screwing up and unscrewing the nuts on the ends of carriage axles and for similar purposes; and the invention consists in certain improvements and devices whereby the nut is quickly grasped by the wrench and firmly held therein until released by the operator.

The improvements consist in certain devices, their combinations, and the equivalents thereof, as will be fully set forth in this specification and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a wrench embodying my invention. Fig. 2 is a top view of the same; and Fig. 3 is a side elevation, partly in section, showing the wrench applied to the nut of a buggy-axle. Fig. 4 is a detail of the spring.

The wrench consists in a handle 1, the outer end 1 of which is bent up, and to this outer end is secured a socket 2 of suitable form and size to receive a carriage-nut. An opening 2 is provided in the side of the socket 2 above the handle 1, and the inwardly-bent end 3 of the spring 3 normally projects into this opening a suflicient distance to engage the side of the nut 4. The spring 3 passes freely down through the opening 1 in the handle 1 and is bent back upon itself, and its other end is fastened by riveting or otherwise to the upwardly-bent end 1 of the handle 1. This arrangement permits the bowed spring 8 to be of such length that its elasticity is not afiected by the small amount of movement to which the spring is subjected, as would be the case the nut when desired.

if the spring were bent short. The tension of the spring is such as to keep the end 3 pressed into the opening 2.

' A lever 5 is pivoted to the handle 1, and the upwardly and outwardly extending slotted end 5 engages the spring 3, so that when the lever 5 is pressed down against the handle 1 the end 3 of the spring is withdrawn from the opening 2, thus releasing the nut 1.

By the means above described I have produced a simple and efficient wrench that can be easily applied to the nut of a carriage-axle inside the hub, will firmly hold the nut in the wrench until it is purposely released by the operator, and can be quickly removed from It will also be noted that the strain of turning the nut is withstood by the socket and is not resisted by the spring. Therefore the nut can be screwed up as tightly as desired without straining the spring. I prefer, however, to use a heavier spring for the larger sizes, in which heavier nuts are to be clamped.

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

1. Inawrench, the combination of a handle having an upwardly-bent end and a socket secured by its outer wall to said upwardly-bent end, said handle having a slot in front of said socket; a U -shaped spring embracing said socket, and having one arm secured to the up wardly-bent end of said handle and the other arm extending freely through the slot in the handle, the intermediate part of said spring forming a loop located beneath the socket; a projection on the inner arm of said spring engaging a slot provided in the inner wall of said socket; a pivoted lever secured to said handle in front of the socket and adapted to withdraw the inner end of said spring, substantially as described.

2. In a wrench, the combination of a handle having an upwardly-bent end and a socket secured by its outer wall to said upwardly-bent end; said handle having a slot in front of said socket; a U shaped spring embracing said means for Withdrawing the inner end of said socket, and having one arm secured to the end spring, substantially as described.
