ANDREW LSEN SEMSIVIGN, GF EVERETT, VIASHINGTGN, ASSIGNGR 0F THREE-FOURTHS TO W. J. LAMRICK, GEORGE OLSON, AND THOMAS SEMSMON, 0F EVERETT, WASI-I- INGT ON.
To all whom it may concern:
Be it known that ANDREW UrsnN SEMS- MON, a subject of Norway, residing at Everett, in the county of Snohomish, State of Tilashington, have invented a new and useful Improvement in iVrenches, of which the following is a specication.
My invention relates to improvements in wrenches, pertaining more particularly to that type known as integral jaw, and it has primarily Jrior its object to provide a novel device of this charac er wherein interchangeable jaws can be eectually used with a common handle or grasp.
It is also an object of the invention to provide a novel device of this character wherein a spring locking means is employed to effectually hold a wrench member or other tool member to the handle or hand grasp.
Furthermore, the invention has for an object, to provide a device of this character which will be simple in construction, etiicient and advantageous in practice, and coinparativeiy inexpensive to manufacture.
l/Vith the above and other objects in view, the invention consists in the details of construction and in the novel arrangement and combination of parts to be hereinafter more particularly referred to.
In describing the invention in detail reterence will be had to the accompanying drawings forming part oil this speciiication, wherein like characters of reference denote corresponding parts in the several views and in which- Figure l, is a side elevation showing the projecting box in section; Fig. 2, is a view in elevation of a wrench member, detached; Fig. 8, is a sectional view of a portion ot the handle, setting forth the structure of the locking spring.
in the drawings, l denotes a hand grasp or handle which may be of any desired construction, it being only necessary that it be provided with the projecting box 2 to receive the reduced portion 3 ot the shank of the wrench member et. One face of the box 2 is cut out, as at 5, and tting within said cut-out portion is the hat spring 6, having its inner end anchored within the hand grasp. Passing through an opening 7, in the opposite tace of the box 2, is pin 8 hav- Specification of Letters Patent.

ing its inner end anchored to the spring 6. rlhe outer or projected end of the pin S, carries a head 9, which is intended to be engaged by the thumb to impart movement to the spring to release the wrench member 4, as will be described.
The free end of the reduced portion 3, of the wrench member fi, is biturcated as at l0, to embrace the pin S, when the wrench member is assembled with the handle. One face of the reduced portion 3, is formed with pocket ll, to receive a nnger l2, carried by the spring G, adjacent its tree end.
Writhout further description, the operation ot the present device is thought to be obvious. It is believed only necessary to state that the wrench member d may be of any desired size or shape, so long as the reduced portion 3 is adapted to tit within the box 2, the outer end of which is open.
My invention is not necessarily limited to wrenches as herein illustrated and described, but interchangeable members of other tools such as screw-drivers and the like, where variable sizes are used, may be substituted without departing from the gist of my invention, providing the shank of the detachable member is of a size and construction to t in the open end of the handle or hand grasp.
W hat claim as my invention, and desire to secure by Letters Patent of the United States, isa
The combination of a handle, an open end box projecting therefrom and having openings in opposed faces, a spring anchored within the hand grasp and itting within one of the openings, a pin passing through the opposite opening and engaging the spring, a head on the pin, a wrench member having a shank insertible within the box, the free end of the shank being bifurcated to straddle the pin of the spring, said shank having a pocket in one of its faces, and a beveled finger carried by the spring adjacent its tree end to enter the pocket of the shank.
