PIPE'THREADERL Application filed April 21, 1922. Serial No. 555,928.
T 0 all whom it mag concern:
Be it known that 1, JAMES W. BoLnN, a citizen of the United States, residing at Alexandria, in the parish of R-apides and State of Louisiana, have invented a new and useful Pipe Threader, of which the following is a specification.
Thi invention relates to pipe threaders and more particularly to an attachment especially designed for sizing a pipe by re moving the inner and outer burrs, incident to cutting the pipe.
Another object of the invention is to provide means to remove portions of the pipe caused by galvanizing or similar processes, whereby the pipe threader may be readlly and easily removed over the pipe to accomplish the forming of threads thereon.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings: 9 Figure 1 is a side elevational view of a threader disclosing devices constructed in accordance with the present invention, as
applied thereto.
Figure 2 is an end elevational view of the threader.
Figure 3 is an elevational view of the front end of the threader.
Figure 1 is a diagrammatic view disclosing the operation of the attachments.
Figure 5 is a diagrammatic view disclosing a pipe in section, and showing the burrs as removed by the attachment.
Referring to the drawings in detail, the threader is of the usual and well known construction and includes a body portion 5 which supports the threading blades 22 and 23, whioh are of the well known construction and adjustable to form threads of various slzes.
Handles 7 have connection with the body portion 5 and provide means for operating the, body portion to accomplish the purpose of the threader. Secured to the body portion 5are the spaced ears 7, between which ears is mounted the supporting arm 8 which extends outwardly and inwardly towards the center of the body portion as clearly shown by Figure 1 of the drawings.
This supporting arm 8 is formed with a suitable opening adjacent to the free end thereof, which opening is designed to accommodate the shank 9 of the reamer 10, a thumb screw 11 being supported by-the arm and extending to a point within the confines of the opening to contact with the shank 9 and secure the reamer in various positions of adjustment. Thus it will be seen that reamers of various diameters may be employed in connection with the supporting arm 8 for reaming pipes of various diameters.
Supported at the forward end of the die is a support 12 which is formed with a hub 13 extending inwardly and having its rear end disposed within the usual opening of the body portion 5 of the threader. Guides 12' are formed on the hub 13, which guides support the blades 6, the blades are provided with pins 19, which pins operate in the cocentric groove 18 of the ring 14:, so that movement of the disk will result in a relative movement of the reaming blades 6 into and out of operation. A controlling handle 21 is formed integral with the ring and extends beyond the surface of the body portion of the threader to be conveniently grasped by the operator to accomplish the adjustment of the ring 14.
Operating at the opposite end of the threader, are the radiating blades 22 and 23 respectively, the blades being arranged in pairs and provided with laterally ex tending pins 23 adapted to move in the grooves 24 associated therewith. The grooves 2 1 are formed in the inner surface of the operating ring 25, whereby movement of the ring will move the threading blades. These grooves are inclined or curved inwardly as clearly shown by Figure 2 of the drawings and are arranged so that portions of the outer grooves overlap portions of the inner grooves.
Thus it will be seen that upon movement of the disk 25, the threading blades will be moved with respect to each other, that is to say, predetermined blades are moved into their operative positions, while the remaining blades are moved outwardly, as shown by Figure 2 of the drawings.
In order that the blades may be moved to accurately form threads, suitable indicating characters are provided on the operating ring 25, which indications may be moved into registry with suitable indicating characters which are provided on the body portion of the threader.
From the foregoing it will be seen that a reamer and cutters are supported at one end of the threading device to remove the inwardly and outwardly extending burrs formed on the end of a pipe, prior to the engagement of the pipe with the thread forming blades.
Having thus described the invention, what is clalmed as new 1s In a pipe threader, a body portion, spaced a JAMES W. BOLEN. Witnesses L. D. ROGERS, ROBERT HARRELL.
