G. BRYAR STRAP WRENCH Original Filed Dec. 15. 192] Patented Oct. 21, 1924.
UNITED STATES PATENT OFFICE.
GEORGE BRYAR, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF THREE-FOURTHS T0 EDWIN W. FORD AND ONE-FOURTH TO JAMES C. FLANNERY, BOTH OF BOSTON,
STRAP WRENCH.
Application filed December 15, 1921, Serial No. 522,454. Renewed March 21, 1924.
To all whom it may concern:
Be it known that I, GEORGE BRYAR, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Strap Wrenches, of which the following is a specification.
The object of this invention is the con struction of a wrench for screwing up piping having finished surfaces, either brass or plated, which shall be capable of adjustment to such piping, which will not slip but will tightly grip the same, and at the same time will not injure the surfaces to which it is applied.
To this end I provide a handle having a head to which an end of the strap is permanently attached, and a shank along which the other end of the strap can be adjustably secured, my preferable means for such adjustment consist ng in threading the shank and mounting thereon an internally threaded collar to which the end of the strap is attached. I also provide means for keeping the threaded collar from turning on the shank relative to the head, in order to maintain the head and collar always in proper relationship. I further improve the wrench by forming its head with a rounded nose by means of which the strap is made to enclose nearly the entire periphery of the piping being acted upon, and thereby to ensure a more perfect grip thereon.
The drawing forming part of this specification is a side view of a pipe wrench embodying my improvements, the piping being shown in section.
The handle 1 has rigidly projecting therefrom a shank 2 threaded for practically its entire length, and having a head 3 ro tatably mounted upon its outer end. From this head projects a lip 6 rounded at its end and having its surface 7 slightly inclined relative to the shank. Upon this surface is fastened an end of a strap 9 by any suitable attaching device, as a screw 10, the strap itself being preferably of ribbon steel.
Mounted on the shank 2 and internally threaded to coact therewith, is a collar 11 having a finger 12 projecting therefrom, the edge of this finger being serrated, as at 13.
The collar 11 and the head 3 are made to turn on the shank 2 in unison by a slender rod 1 1 rigid with one thereof but slidable in an eye 15 of the other member. Thus arranged, when the shank is revolved it turns equally in both the head and collar.
The end of the strap 9 not attached to the head 3 is provided with a slotted plate 16 adapted to be engaged with the serrations of the finger 12, either close to the collar or farther therefrom, as the best action of the wrench demands.
In using this wrench, the plate 16 is removed from its engagement with the fin ger 12 to permit the strap 9 to be passed about the piping to be turned. Then the handle 1 is rotated until the collar 11 is propelled thereby to a point at which the finger 12 readily engages the slotted plate 16, with the lip 6 pressing the adjacent section of the strap tightly against the surface of the pipe, as 19. If the pipe is comparatively small in diameter, the plate 16 is engaged with a serration close to the collar, but if larger, the plate is put into control of a serration farther from the collar.
The handle 1 is again turned until the strap is put under tension, and then the handle is swung in a direction to maintain the nose or lip 6 in advance of the body of the strap. This causes the strap to tighten up on the piping until the grip becomes sufficient to force the pipe to turn with the handle. When the handle is moved in the opposite direction, the strap releases its hold said shank, and said collar having an eye slidable on said rod.
In testimony that I claim the foregoing invention, I have hereunto set my hand this 10th day of December, 1921.
GEORGE BRYAR.
