Description
UNITED STATES PATENT OEEIcE.
W'ILLAM KEARNEY, OF UNION, BERGEN COUNTY, AND FRANCIS KEARNEY,
OF NEVARK, NEV JERSEY.
IMPROVEMENT IN PIPE-TONGS.
Specification forming part of Letters Patent No. 35,762, dated July 1, 1862.
To all whom it may concern:
Be it known that we, WILLIAM KEARNEY, of Union township, .Bergen county, and State of New Jersey, and FEA'NcIs KEAENEY, of Newark, Essex county, and State aforesaid, have invented a new and useful Improvement in Pipe Tongs or 4Wrenches; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being `had to the accompanying drawings, making a part of this specitication, in which- Figure l is a side view ot' our invention;
Fig. 2, au edge view of the same; Fig. 3,'asidc` means for readily adjusting the sliding jaw4 relatively with the fixed jaw, so that the wrench may be adjusted with facility to 'suit different-sized pipes or tubes,and at the same time be capable of being rmly secured in position, so that it cannot casually move when the wrench is applied to its work.
To enable those skilled in the art to fully understand and construct our invent-ion, we will proceed to describe it.
A represents one leg of the wrench or tongs, which has a curved jaw, B, formed at one end, the portion c of said leg adjoining the jaw being of rectangular form and somewhat taper, the front and back edges of a being somewhat beveled to form the taper, and the two other sides being parallel with each other. The other part,vb, of said leg is vcylindrical and forms the handle which is grasped by the operator in using the implement. The widest part of a adjoins the part Z) of theleg,as shown clearly in Figs. l and 3.
On the rectangular taper part a of the leg A thereis iitted asliding collar, C, the interior of which is considerably wider than the lowest and widest part ofthe portion a of leg A,
so as to admit of a key or wedge, D, being inserted in it at the back edge or surface of a.
The two other sides of the collar are in direct contact with the parallel sides of a, no play,
being allowed. The ends of the key or wedge D are bent or formed with lips c c, which project beyond the upper and lower edges of the collar O, and retain the wedge in the collar, as shown in Figs. l and 3. The key or wedge is provided with two laterally projecting arms, Z d, which extend through holes in the collar and project a short distance out from it..
E is a thumb-screw which passes through the back ofthe collar O, and bears against the key or wedge D; This thumb screw is provided with a head, e, which as the screw is turned into the collar and bears against D also bears against the arms d d thereof, as shown more particularly 'in Fig. 3.
To the front side ofthe collar C there is at tached. by a sector-joint, f, a leg, E, having a serratedjaw, F, at the end, which isj ust within thejaw B ofthe leg A. The other part of the leg E', at the opposite side of the joint f, is rounded to form a handlagdike b of the leg A.
The article to be turned or operated upon is grasped between the two jaws B F,as shown in Fig. 1, the operator pressing the two handles b g toward each other, and in order to adjust thejaw F to suit tubes or pipes of differ ent diameters the screw E is turned out or unscrewed, so as'to take all pressure oft from the key or wedge D and allow the vcollar to be moved on the part a of the le,O` A. XVhen the jaw F is iu the proper position,the screw Eis screwed up and the key or wedge D thereby pressed against the outersurface of the parta ot' the leg A, while the inner surface of the front part ot' the collar O bends against the opposite edge or surface. By this arrangement the collar O is tirmly secured on the part a, as a good bearingsurface is obtained the whole length of the collar, and in consequence of a being somewhat taper the collar cannot be forced down on a, or from the jaw B, under any pressure to which it may be subjected through jaw F when the wrench is in use.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
The collar C, with the leg E attached, in
combination with the wedge D, thumb-screwA
