WILLIAM H. BROOK, OF BROOKLYN, NEW YORK.
FLANGE-WRENCH.
SPECIFICATION forming part of Letters Patent No. 542,922, dated July 16, 1895.
Application filed November 20, 1894- Serial No. 529,386- (No model.)
To all whom it may concern.-
Be it known that 1, WILLIAM H. BROOK, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Flange-Wrench, of which the following is a full, clear, and exact description.
My invention relates to a wrench particularly adapted for screwing flanges upon pipes,
ence indicate corresponding parts in all the views.
Figure l is a perspective view of the wrench, illustrating also its application to a flange of a pipe. Fig. 2 is a plan view of one side of the wrench, and Fig. 3 is a plan view of the opposite side.
In carrying out the invention the wrench consists of a handle 10 and a head 11. The said head is of substantially segmental construction, being provided with teeth 12 at each of its ends, whereby. the said head has I two working-faces and is therefore capable of being reversed when necessary. In connection with the head an-arm 13 isemployed, which arm is pivoted upon one side face of the handle adjacent to the head, and the pivot of the said arm is about central with respect to the space between the working-faces of the head. The arm 13 is of such length that it extends over and beyond the outer or convexed face of the head and is-provided at its outer end with a stud let, the stud being so located that the arm may be carried in direction of either of the working-faces of the head without the stud interfering with the same. The pivot-pin 15 of the said arm may be either attached'to the handle or made an integral portion of the same.
The operation of this wrench is plainly shown in Fig. 1, in which it will be observed that one toothed or working face of the wrench is placed in engagement with the periphery of the flange A, while the arm 13 is carried manner to screw it on the pipe B, and when the flange has been turned as far as possible the arm is disengaged from the flange and its studis placed in the next lower bolt-hole. This operation is continued until the flange is properly screwed to place.
It is evident that this wrench, by reason of its two working-surfaces, may be used either right or left, and may be employed to remove a flange from a pipe as well as to screw one on the same.
The wrench is simple, durable, and economic, comprising practically but two parts, since the head and handle are made preferably from one piece of material.
Having thus described my invention, I claim as new and desire to secure by Letters Paten-t- 1. A flange wrench, comprising a handled head, an arm pivoted thereto, and a stud projected from the arm substantially parallel to its pivot, the arm connecting the pivot to the stud being located entirely to one side of the handle, so that when the stud is swung to either side of the handle, there will always be a free space between the stud and the head to permit the tool to be engaged with a flange, substantially as described.
2. A flange wrench comprising a head having a biting face on each side and provided with a handle and an arm pivotally connected to the head and extending beyond the biting faces and provided with a stud projecting from its free end substantially parallel to its pivot pin, substantially as set forth.
3. A flange wrench comprising a head having a lug projecting from one face and having a biting face on each side of the lug, and being also provided with a handle and an arm having a perforation to receive said lug, the end of said arm extending beyond the end of the head and having a stud projecting from it parallel to the said lug on the head, substantially as set forth.
