To allfwliomit may concern.;

Be it known that LJEssE A. BEAN, a

residing at Texarkana, in the county of Bowie and Stateof Texas, have invented of which the following is a specification.

rlhe object of the present invention is to improvefthe construction ofV wrenches, and to provide asimple,

and pipe r`wrench of order'by rough handling.-

.With these and .other objects ineview', the invention consists in the 'constructionand novel ycombination of parts Vhereinafter the accompanying drawing,` and pointed out fin the claim vhereto i appended; it being understood that f various changes inthe form, propor'f' tion, size and minor details of construction,`

v)within the scope'of the claim, may be ref so sorted to without departing from the spirit m or sacrificing any of the advantages of the invention.

In the accompanying drawing in which is illustrated the preferred-embodiment of the invention, 1 designates a @hollow` handle forming a longitudinal opening 2 for the reception of shanks Sland 4 of relatively Y f slidable nut and pipe engaging jaws 5 and 6. The Yhandle-is enlarged'lat its terminals to form relatively Xed inner jaws 7 fand 8, arranged to coperate -with `the movableI as shown7 and' engaged by tudinal opening of the handle 1.

This construction. provides a well balanced wrench, which is adapted to be easily operated and eect a material saving in time and obviating the necessity of employing separate pipe and nut wrenches.

What is claimed is A wrench of the class described including Copies of this patent may be obtanedifor the relatively movablek a hollow handle having a longitudinal opening extending entirely through it and enlarged at one end, said handle being provided at a point intermediate of its ends with a transverse opening and having its terminal portions enlarged to form inner relatively fixed jaws, outer relatively slidable jaws having shanks extending into the longitudinal opening from the opposite ends thereof, the shank of one of the jaws being relatively long and provided with a threaded portion and extending inwardly beyond the transverse opening, the shank of the other outer jaw being relatively short and pivotally connected to the threaded shank and adapted to oscillate in the enlarged end of the longitudinal opening of the handle, an adjusting nut operating in the transverse opening of thev handle and engaging the threads of the relatively long shank, and an exteriorly arranged'spring piercing the hollow handle at the enlarged portion of the longitudinal opening and bearing against the said relatively short shank.
