PATENT lrrrcs.
JOHN THOMAS IVILLIAMS, OF LIVERPOOL, ENGLAND.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 793,257, dated June 27, 1905.
Application filed September 27, 1904. Serial No. 226,172.
To all whom it may concern:
Be it known that I, JOHN THOMAS W'ILLIAMs, a subject of the King of Great Britain, residing at 131 Lambeth road, Liverpool, in the county of Lancaster, England, have invented new and useful Improvements in IVI-enchcs, of which the following' is a specification.
This invention has reference to wrenches for turning pipes, nut-s, rods, and the like; and it relates more particularly to that type which comprises two limbs, one comprising an upper jaw and a stern and the other the lower jaw and a stem, the two being' jointed by a joint-pin passing through both and forniing a hinge below the face of the lower jaw. According to the present invention a wrench of this kind is so constructed that the one jaw may be adjusted in relation to the other so as to take different sizes of pipes, nuts, or the like without the necessity of withdrawing the hinge-pin, which in this case is or may be permanent and Hxed in one of the limbs, while the stem of the other limb or jaw is provided with a plurality of gaps or sockets, which form so many centers for the hinge-pin to be moved to and rest in to adjust the wrench or spanner for taking different sizes of articles.
In the drawings, Figure l is a side View, partly in section, of the wrench. Fig'. 2 is a like view of a modification. Figs. 3 and @L are further modifications.
Referring to the drawings, one limb consists of an upper jaw l and a stem 2 and the other consists of the lower jaw 6 and stem T, and these two limbs are held together and work in relation to each other upon and about a joint hingepin or pivot 5, which passes through both limbs.
The stem 2 in the construction shown in Figs. l, 2, and 3 is provided with a longitudinal slot 3, having a plurality of gaps or notches '-L leading out of it, forming so many centers or sockets for the hinge-pin 5 to be moved to and rest in to adjust the Spanner or wrench for taking di'erent sizes of articles, and the pin is held in one of the sockets or gaps by the spring 9, which prevents the two limbs from moving away from each other and the pin coming* out of the sockets at all times.
The lower jaw-limb 7 is made of sheet metal folded over so that the two cheeks lie one on either side of the other limb-stem 2, and the hinge-pin 5, which may be a rivet, screw, or aboltand nut, passes through these cheeks.
In theconstruction shown in Figs. l and 2 the spring 9 is fastened in the channel of the outer limb, in Fig. 1 it being fastened to the block 8, which lies between the end of the cheeks of the lower jaw-limb, forming the jaw 6, where they are fastened together, while in Fig. 2 it is fastened to the back of the stem 7 by a removable screw-pin lO. In the former case the sockets or notches 4 lie on one side of the slot 3, and in the other case they lie on the opposite side of the slot, and this constitutes the chief difference between the two constructions of spanners.
In Fig. 3 the shape of the sockets or gaps a is curved, and the met-al of the lower part is carried up so that the pin 5 will lie and be held behind this carried-up part or hook-lip and will not come out of the recess or socket of itself.
In the modified construction shown in Fig. L the gaps or pivot-notches et are formed in the edge of one of the limbs of the wrench in lieu of the center of it, as in the other form shown.
That is claimed isl. A wrench comprising' a shank having an outer jaw thereon, said shank being provided with a slot having a plurality of gaps therein, a second shank of channeled form having its sides at one end curving upwardly so as to form two jaws between which the lirst-rnentioned shank lits, a pivot passing through both sides of the second shank and engaging any one of the gaps in the lirstshank and a spring secured in the channeled shank and engaging with the first-mentioned shank.
2. A wrench comprising' a shank having an outer jaw thereon, said shank being provided with a plurality of gaps, a second shank of channeled forni, having a jaw thereon, a pivot passing through both sides of the second shank, and engaging' any one of the gaps in the shank, and a V-spring in the channelshank having an eye at its lower end, and disposed between the back of the other shank, In testimony whereofIhave signed my name and the back of the channel-shank, and ento. this specication in the presence of two subgaging with the back of the Erst-mentioned seribing Witnesses.
shank, and adapted to press it toward the JOHN THOMAS WILLIAMS 5 pivot, and a screw-pin passing through the Witnesses:
two sides of the channel-shank and the eye of FRANK E. FLEETwooD,
the spring, substantially as described. GUY AKE.
