ALLAN R. LAKIN, OF BALTIMORE, MARYLAND.
PIPE-BENDING TOOL.
SPECIFICATION forming part of Letters Patent No. 780,756, dated January 24, 1905.
Application filed November 16, 1904- Serial No. 232,981.
tool.
The object of the invention is to provide a tool especially adapted for use in bending pipe that is being fitted in floors, partitions, and walls, so as to avoid frequent cutting and the use of elbows or angle-pieces.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a View of the tool which has made a right-angled bend in a piece of pipe. Fig. 2 is an elevation of the pipe-holding end of the tool. Fig. 3 is an elevation of the pipebending end of the tool. Fig. 4 is an elevation showing the open side of the tool.
The tool consists of a solid forged or cast body A, of metal, having an open side 6 between fixed jaws 0 d. The inner longitudinal space 6 is partly circular in cross-section to receive a pipe. The body has at a side which is at a right angle with respect to the said open side 6 an inclined screw-threaded shank f. The pi pe-holding end 9 of the body is Hat, and at this end the inner space e has a number of crosswise serrations h similar to screwthreads, which constitute the means to prevent the tool from slipping on the pipe. The jaw 0 is straight; but the fixed jaw d at the pipe-bending end has a curved lip OZ and the inner space 6, which is straight for a short stretch, widens at the side corresponding with the said curved lip, as at a, and forms a sort of a bell-shaped end. This is the pipe-bending end, and the widened or bell-shaped part 6 has a series of curved cross-serrations 7b which will impinge against the side of the pipe at the point where the bend is made and prevent slipping. A suitable length of pipe z', to serve as a lever or handle, is attached to the shankf. The screwthreaded shank f inclines in a direction away from the widened or bell-shaped part e in order to prevent the lever or handle 6 when pressed down from striking the floor or other obstacle in making a right angle bend in a pipe.
The manner of using the tool will be obvious from the illustrations and descriptions.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A pipe-bending tool comprising a solid metal bodyhaving a flat pipe-holding end, 9, and an irregular bell-shaped pipe-bending end; two fixed jaws between said endsone of which is straight and the other has at the bending end a curved lip, (2, said two jaws forming a side opening to a longitudinal inner space, 6, whichis widened or bell-shaped at one side adjoining said curved lip; crosswise serrations, h, at the pipe-holding end of said inner space; and a shank.
2. A pipe-bending tool comprising a solid body having two fixed jaws one of which is straight and the other has'at the bending end a curved lip, cl, said two jaws .forming a side opening to a longitudinal inner space, 0, which is widened or bell-shaped at one side adjoining said curved lip; and a shank which inclines in a direction away from said widened or bellshaped part.
In testimony whereof I aflix my signature in presence of two witnesses.
