IMPROVEMENT IN WRENCHES.

Specication forming part of Letters Patent No.' 52,965, dated March 6, 1866.

o all whom it may concern Be it known that I, A. Gr. GOES, of the city and county ot' Worcester, and State of Massachusetts, have invented certain new and use ful Improvements in Wrenches; and I do hereby declarev that the following is a full, clear, and exact description of the saine, reference being' had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a longitudinal section of a wrench with inyimprovenients applied thereto; and Fig. 2 represents a similar view with a modification ot' my invention.

In the drawings, A represents the stationary jaw, B the bar, G the shank, D the movable jaw, E the 'screw by which the movable jaw is operated, and F the handle, of a Goes wrench with my improvement applied thereto.

As heretofore constructed there has been some difficulty in holding the ferrule G, in which the rear of screw E is stepped, in place, owing to the great back pressure. This pressure is sometimes so great as to force the ferrule back so as to crush orjain up the front of the handle. To remedy this difficulty a notch, ct, is cut in the upper edge of the shank, into which the projection b of the rear part of the ferrule H drops when slipped on, as indicated in Fig. l ofthe accompanying drawings. The ferrule in this instance, it will be observed, is made in two parts, the part Gr fitting the shank supporting the rear end ofthe screw E and receiving the back strain orpressure of the rosette I, while the part H abuts against the rear of G and receives the front end of the handle F.

By this mode of construction it will be seen that the back pressure of the rosette against the fer-rule is prevented from coming against the handle, since it is all borne by the shank G, in consequence of the projection b dropping into the notch e in shank G. The handle is therefore not liable to be crushed between the rear screw-nut, J, and the ferrule, nor is the ferule liable to be forced back out of place.

In Fig. 2 a modification ot' my invention is shown. In this latter case the ferrule G is all in one piece, and the entire projection c drops down into notch s d in the shank, and thus is held from heilig pushed back against the handle F. After the handle F has been driven in and nut J screwed up the ferrules in both cases are retained with their projections securely in the notches, as shown in the drawings.

Although Fig. 2 represents a modified form of this invention, yet as the. construction ot' the ferrnle employed is essentially dilferent from that employed in Figi, and as it is contem plated to apply for separate Letters Patent therefor, I wish to be understood as laying no claim to itin this patent.

What I do claim is- Making the ferrule in two parts, as shown at G and H, in combination with holding one of them up against the back pressure of the rosette I and screw E by means of the projection b and notch a, substantially as set forth.
