906 FEDERAL REPORTER. �the inventor, November 10, 1863, for an "improvement in wrenches." The specification of the reissue is signed by Loring Coes, and is as follows, inchiding what is inside of brackets and what is outside of brackets, omitting what is in italics : �" Figure 1 representa a prospective view of [a 'Coes wrench' having the said iaft's improvements applied thereto] my improvement, and figure 2 repre- senta [sections of detached parts of the wrench shown in figure 1] a detached View of the 'rosette' and therewith oonneoted. Simiiarletters of reference indicate like paiis in the drawings. * * « [The nature of the said Taft's invention relates to' a mode of constructing the Coes wrench patented April 16, 1841, in such a manner that the handle shall be relieved f rom the back-thrust or strain of the rosette screw, when the wrench is used. In my said wrench the rosette presses against the ferrule, and the ferrule, in turn, against the front end of the handle, whereby the handle was often split and broken. In the drawings] A is the shank of [the] my wrench ; B the stationary jaw ; and B' the sliding jaw, through the part B" of which the operating screw, C, works. D is the rosette, formed in one piece, as shown, with the screw, C, [as shown,] and journalled, at a to [the] ferrule, E. Parallel grooves, d, d, d, [in this instance] are eut in the shank, A, [at right angles to the Une of motion of the moyable jaw, B",] in which [grooves] projections e, e, e, of the rosette turn. The pro- jections e, e, e, are made parallel to each other, and are bevelled on one side, as shown, to lessen the friction of the rosette [in] upon turning. The opera- tion is as follows: To adapt the opening between the jaws to the size of the object to be clasped thereby, the operator turns the rosette to the right or left, as the size of the object [may require] will indicate, which will turn the screw in the part, B", of the sliding jaw, B', thereby increasing or diminishing, as the case may be, [and, as to the way turned, will increase or diminisli] the distance between the jaws, as required. The [advantage] advantages of hav- ing a rosette of this [improvement] /o?-to is that it sustains the pressure which [would otherwise] otherwise would corne [upon] on the [handle is transferred to the shank of the wrench, thus obviating one and really the only serious objection to the said Coes wrench ,]/e>VMZe, E, which pressure is often so great as to hreak it off, or displace it, thus rendering the whole wrench useless. Hav- ing thus described my improved wrenoh, I am aware that the [rosettes] rosette of screw wrenches [have] has heretofore heen constructed with [screw threads] a screw thread, and [such devices are not claimed] / do not clairn such devive, but what [is claimed as the invention of the said George C. Taft, and desired to have secured] I daim atid desire to seoure by letters patent is;" �Eeading in the foregoing what is outside of brackets, iucluding what is in italics, and omitting what is inside of brackets, gives the text of the specification of the original patent. There are three claims in the reissue, as follows : �"(1) An improved Coes wrench, so constructed that the thrust or back strain of the rosette screw, when the wrench is used, shall be borne by the shank, instead of the handle of the wrench, substaiitially as described, (2) A notch ��� �
