Letters Patent No. 65,550, dated Jaua 11, 18.67. v

IMPROVEMENT IN WRENGHES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM P. DUNLAP, of Maquoketa, in the county of Jackson, and Stal-c of Iowa, have invented a new and useful Improvement in Wrenches; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings7 and letters of reference marked thereon, making a part of this specification, in which- Figure luis a perspective representation of my wrench.`

Figure 2 is a vertical elevation of the same.

Figure 3 is a plan view of the revolving.:r die.

-The nature of my invention consists in the use of a revolving die, suitably arranged and securedin a forked handle, and having in the sides of said die suitable openings for fitting on to nuts and turning the saine, when they' occupy positions beyond the reach of ordinary wrenches. The nature of my device will be better understood by reference to its peculiar construction shown in the drawings.

A is the handle, which is `made with the prongs D, for the purpose of providing a suitable support for the die B, and allow it to revolve and have either of its faces presented to the nut to be turned. In order to hold the die B firmly, Aand yet so as to revolve between said prongs D, pins S are putthrough the saine and into said die, by which means the Wrench may operate equally as well when the handle A occupies a vertical or inclined position as when placed horizontally. This arrangement is very important for turning nuts in cylinders and other places difficult to reach, where several wrenches of especial construction are now used to accomplish the desired purpose. At fig. 1 thc opening 2, made for fitting over the nut, has its sides madcparallel with those of the die B. The openingin thc opposite side is made diagonally with said sides, as seen at :2. The smaller openings 4, gs. 1 and 3, are made in the same manner and to t small nuts. This method ofmaking,r the holes in the die is important for turning nuts when but little room is had for moving the handle A. When necessary several dies B may be fitted to one handle, by which means any ordinary-sized nut may be turned, simply by taking out the pins S and putting a die having the proper-sized hole iu the handle.

Operation. The methodof turning nuts with my wrench is so similar to that of those in common use that no instruction is necessary, except when using the handle A directly over the bolt, in which case a common handle, C,.

may be fitted to A, and the wrench turned similar to an auger.

I-Iaving thus described my device, what I claim, and desire to secure by Letters Patent, is- A wrench, constructed substantially as and for the purpose set forth.

WILLIAM P. DUNLAP.
