CHAIN PIPE WRENGH.
N0. 480,140. Patented Aug. 2, 1892.

CHAIN PlPE-WRENCH.
SPECIFICATION forming part of Letters Patent No. 480,140, dated August 2, 1892.
Application filed February 23, 1892l Serial No. 422,440. (No model.)
To all whom it may concern: To one side of the lever l, at the upper end Be it known that I, JOHN F. SAUERMAN, of of the same, is formed an extension 4, which the city of Coal Hill, county of Johnson,and is also provided with a circular opening 5, State of Arkansas, have invented certain said opening being of smallerdimensions than new and useful Improvements in Chain Pipethe opening 3 before referred to. 55
Wrenches, of which the following is a full, 6 represents a chain constructed of flat clear, and exact description, reference being links and which maybe of any suitable length, had to the accompanying drawings, forming one end of which is mot/ably attached to the a part hereof. extension 4 of the lever by means of a bolt 1o My invention relates to improvements in or rivet 7 passing through an enlargement 8, 6o chain pipe-wrenches; and it consists in the formed on said end of the chain, and through novel arrangement and combination of parts, the opening 5, formed in said extension, by as will be more fully hereinafter described, means of which the chainA is free to move. and designated in the claim. The gripping-jaw which I employ may be In the drawings, Figure 1 is a front eleva-V formed by forging the same or made in parts, 65 tion of my complete invention, showing the as illustrated in the drawings, the construcsame applied to a pipe and in position to turn tion of which I shall now proceed to describe. the same. Fig. 2 is a perspective view of the 9 represents the gripping-jaw, which conjaw forming a part of my invention. Fig. 3 sists of two plates 10, shaped and formed in zo is a detail viewin plan showing the upper end the manner as hereinafter described. 7o
of the lever, and Fig. 4 is a top plan View Referring to Fig. 1 as a better illustration, showing that end of the jaw for receiving the 11 represents the rounded enlarged portions free end of the chain. of the said plate and said portions provided The objectof my invention is to greatly with suitable openings 12, through which a improve the chain wrenches heretofore con bolt or rivet 13 is adapted to be passed, pre- 75 structed; and it consists, essentially, of three mising, however, that said bolt also passes elements-namely, a lever, chain, and movathrough the opening 3, formed in the upper ble jaw-which when the parts are united, as end of the lever 1, forming a movable connechereinafter described, the pipe to which the tion between said jaw and'lever. That su r- 3o said invention is applied is gripped by the face of the plates 10 which comes in contact 8o manipulation of the lever in the proper diwith the outer surface of the pipe to be turned rection and will release its grip upon said are provided with teeth l4,which areso formed pipe when the said lever is moved in the opas to slide upon the pipe in one direction,but posite direction. grip the said pipe when the jaw is moved in My invention is especially constructed to the opposite direction. Leading from the said 85 overcome all objections that other wrenches enlarged portions 1l of the said plates 10 are of the same type possess, the most important angular-shaped extensions 15, the inner surobjection being disfiguring the said pipe in faces of the horizontal portions of the said many Ways by the employment of a bar which plates shaped in a manner hereinafter de- 4o is brought in contact With the surface of the scribed. 90 pipe. 16 represents a bolt or rivet which passes Referring to the drawings, 1 represents a through the said plates 10 for holding the lever, which is tapering in longitudinal disame a proper distance apart, and, further, mensions and rectangularin cross-section,the by the use of the said bolt the said plates are dimensions, however, being only a matter of made rigid with one another. 95 convenience. The upper end 2 of the lever 1 In Fig. 4 I have shown more clearly the is suitably shaped and provided with a circuconstruction of the horizontal portions 15 of lar opening 3, which provides means for atthe plates 10, showing in addition to said contaching the movable jaw, as hereinafter destruction the location of the chain between 5o scribed. said plates and the manner of securing the roo said chain within and between the said plates. Looking from the end of the said horizontal portions 15 of the said plates, 17 represent cut-away portions formed on the inner surfaces of the said plates, leaving two projections 1S, between which projections one of the links of the chain 6 is adapted to be inserted and the adjacent links located within the spaces formed by the said cut -away portion 17.
By the construction of the plates as above described the chain is held rigidly by said jaw, which is absolutely necessary in order that the gripping will take a firm hold upon the pipe to be turned and when the lever l is moved in the proper direction for turning said pipe.
In Fig. 1 is shown the wrench above described in its proper position upon a pipe, which when the level' Z is moved toward the right looking at said gure the gripping-jaw 9, or more properly the tooth portion ot' the saine, will be brought in contact with the surface of the pipe to be turned, the resistance of the lever 1 being at that point where the chain G unites with the said level', and the resistance of the jaw 9 being also upon the chain 6, causing not only the said gripping portion of the jaw to corne in contact with the pipe, but also the chain G, which also, in addition t-o the said jaw, acts to grip the pipe. Vhen the lever 1 is moved in the opposite direction to that above described, the jaw would be moved from the pipe, there being no resistance, and the entire wrench allowed to be moved freely about the pipe.
The wrench above described is not only simple in construction, but very ett'ective in its results and can be used under all circumstances, either upon small or large pipes, with like results.
Having fully described my invention, what I claim is A chain pipe-wrench consisting of a lever 1, an extension 4, formed on one side of the saine, a chain one end of which is movably attached to the said extension, a jaw 9, adapted to be movably attached to the said lever and composed of plates 10, teeth 14, formed on the impinging surfaces of said plates, angular extensions 15, formed by the said plates, a bolt 1G for rigidly attaching the said plates together, cut-away portions 17, formed on the inner surfaces and at the ends of the said plates, leaving projections 1S, and a bolt or rivet 18 for attaching said jaw to the said lever, substantially as described.
In testimony whereof I aliix my signature in presence of two witnesses.
JOHN F. sAUERMAN.'
