'- 1.. E. PECK PIPE} WRENCH Aug. 15 1933 Original Filed Jan. 2, 1931 Z;zJe iaawZPec/r.
Patented Aug. 15, 1933 PIPE WRENCH Louis E. Peck, Greenfield, Mass., assignor to Mechanics Tool & Wrench Company, Greenfield Mass., a Corporation of Massachusetts Application January 2, 1931, Serial No. 506,047
Renewed February 14, 1933 2 Claims, (01. 81-105) The principal objects of this invention are to reduce the cost and increase the strength of the frame of a pipe wrench and also to substitute for the usual two springs, a single spring which may be replaced without tools in case of breakage.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the drawing in which Fig. 1 is a side view of a pipe wrench constructed in accordance with this invention;
Fig. 2 is a side view of the frame by itself;
Fig. 3 is an end view of the frame as indicated by the arrow 3 in Fig. 2, and
Fig. 4 is an edge view as indicated by the arrow 4 in Fig. 2.
The wrench is shown as provided with the usual jaws 10 and 11, the jaw 10 having a shank 12 provided with a screw-thread 13 and the jaw 11 having an extension 14 which constitutes the handle. A nut 15 as usual is screwed on the threads 13 for adjusting the wrench.
The frame consists of two pieces of sheet steel 16 and 17, each bent into a U-shaped form and one having its ends extending outwardly enough to enclose the flat sides of the other. These two parts are riveted together by a rivet 18 and pivoted to the handle 14 by a pivot stud 19 which also helps to hold the two parts together. The part 16 of the frame is provided with a slot 20 for receiving the nut 15. The back of the part 16 of the frame is straight inside so as to engage the back of the shank l2 and especially the screw-threaded portion of it. The opposite side of the portion 1'7 is slanted to limit the mo tion of the handle 14 about the stud 19 on which the handle is pivoted.
On the stud or rivet 18 inside the frame'is held a spring 21 which has an arcuate notch 22 in its body approximately half way between the accompanying ends. Thus the spring 21, having two ends projecting from the rivet 18, both bearing on the handle 14, will be held against the stud and will not easily become displaced. It is enclosed within the part 16 of the frame and obviously is held in position against any ordinary accidents. At the same time it can be removed from the rivet and drawn out of the frame along the handle and replaced by any one without the use of tools.
The manufacture of the frame of two pieces of steel formed up in a very simple manner and riveted together results in increased strength over the usual malleable iron frame that has been used for so many years. Furthermore, the
cost of construction of the frame is reduced. The steel frame can be made so that it can have a more attractive appearance malleable iron frame and the rially improved by that no tools have spring and that the a single one also ture and maintenance.
two spring than the ordinary wrench is matethis construction. The fact to be used to remove the s are replaced by reduces the cost of manufac- Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be any person skilled made therein by in the art without departing from the scope of the invention as expressed in the claims. ed in this respect Therefore I do not but what I do 1. A pipe wrench having two jaws, a
wish to be limitclaim is:--
handle on one jaw and a screw-threaded shank on the other, and provided with thread, a frame having a slot a nut on the screwfor the nut, said frame comprising a piece of sheet steel bent into U-shaped form extending around the handle and a second piece of U-shaped sheet steel extending around the screw-threaded shank, projecting outside the ed thereto, the two parts of the first named steel piece, and rivetframe being pivotally connected with the handle.
2. As an article of manufacture, a frame for a pipe wrench comprising a U-shaped piece of sheet steel, constituting a guide for the shank of one of the jaws of the wrench, and a second U-shaped piece of sheet handle passes, the other jaw b steel within which the eing on the handle, one piece of sheet metal extending inside the other, and two rivets for securing the two parts of the frame together, one of said rivets serving to pivot the handle to the frame.
