SAMUEL BOOTHROYD, OF AMESBURY, MASSACHUSETTS.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 456,265, dated July 21, 1891.
` Application tiled August 11,1890. Serial No. 361,762. (No model.)
To @ZZ whom it may concern:
Be it known that l, SAMUEL BoorHRoYD, a citizen of the United States, residing at Amesbury, county o f Essex, and State of Massachusetts, have invented certain new and useful Improvements in lVrenches,of which the following is a specification. Y
My invention relates to improvements in wrenches; and the objects of the invention, together with the novel features thereof, will appear in the following description, and be particularly pointed out in the claim.
Referring to the drawings, Figure 1 is a side elevation of a wrench constructed in ac- Fig. 2is asimilar View of the wrench,the same being adapted for operating upon nuts. Fig. 3 isa vertical longitudinal section. Fig.4 is a transverse section. Fig. 5 isa detailin elevation of a pivoted jaw adapted for operating upon rib-couplings. Fig. (i is a detail in elevation of one of the swiveled heads.
Like numerals of reference indicate like parts in all the figures of the drawings.
1 designates the cylindrical shank of the wrench, which atits lower end is provided with a suitable handle 2, and from about midway to its upper end isV provided with screw-threads 3. Abovev the screw-threads the shank or stock is reduced toY form a cylindrical tenon 4. Upon the screw-threads is mounted a revoluble sleeve or nut 5, inter-v nally bored and threaded to receive the shank, and at its lower end provided with a milled periphery G, adapted to be grasped by the thumb and foreiinger of one hand, while the shank is turned with the other. From the sleeve extends a pair of perforated lugs or ears 7, through which and the corresponding perforation formed-in the pivoted jaw 8 is passed a removable bolt 9, maintained in position by a nut 1U. The jaw S is extended in rear or below its pivot and has interposed between its inner surface and the sleeve 5 a a curved spring 11, designed to press said end away from the shank and sleeve. Above its pivot the jaw is curved, as at l2, the inner edge thereof being in some instances plain, as shown by full lines in Fig. 1, or toothed, as shown by dotted lines in said figure. Other forms of pivoted jaws may be substituted, as-for instance the angular jaw shown 2.
Various kinds of jaws may be employed in connection with this wrench and in connection with the pivoted jaws above mentioned. In Fig. 1 the jaw 13 has aconoaved plain upper end or face. As shown in Fig. 2, the head `may be square or cubical, and, as shown in Fig. 3, the head may be provided with a con-v series' of longitudinal grooves 15 and the sleeve 5 with a set-screw 16 for 'engaging any one of t-he grooves, and thus retain the sleeve against rotation and yet prevent the inner ends of the set-screw from mari-ing or injuring the threads of the shank. I
In Fig. 5 I have shown a curved jaw having a plain inner edge and provided at its eX- tremity with a transverse rib or bite 17. Such formof jaw I have found especially adapted for operating upon rib-couplings.
The operation ofthe wrench is as follows: The shank 1 is rotated with one hand and is held in the other hand, the movable head 13 resting upon the object, such as the pipe, nut, rod, the. In this manner the jaw 8 is drawn to the upper side of the object in the same clamp. Itis now simply necessary to operate the wrench in the usual manner.
Having described my invention, what. I claim isl In a wrench, the combination, with the cylindrical shank threaded at its upper end, terminating in a reduced tenon, and provided with a series of longitudinal grooves, of a head swiveled upon the tenon, a sleeve ha ving an internally-threaded bore mounted upon the shank, a jaw pivoted to the sleeve and extended in rear of its pivot to form a handle, a flat-spring interposed between the handle and sleeve, and a set-screw mounted in the sleeve and engaging a groove of the shank` substantially as specified.
