JOHN B. KAISER, OF SALEM, OREGON, ASSIGNOR OF ONE-HALF TO J. A. BERNARDI AND G. E. DUNSFORD, OF SAME PLACE.
REAMER ATTACHMENT FOR PIPE-THREADERS.
SPECIFICATION forming part of Letters Patent No. 621,305, dated March 14, 1899. Application filed April 23, 1898. Serial No. 678,591. (No model.)
To all whom it may concern:
Be it known that I, J OHN B. KAISER, a citizen of the United States, residing at Salem, in the county of Marion and State of Oregon, have invented new and useful Improvements in Reamer Attachments for Pipe-Threaders, of which the following is a specification.
This invention relates to devices for re moving burs from the inside of pipes, which burs are formed in the operation of cutting pipes into lengths; and its novelty and advantages will be fully understood from the followingdescription and claims when taken in conjunction with the annexed drawings, in which- Figure 1 is a sectional View of a die-stock and die applied to a part of a pipe on which a thread has just been formed, my improvements being illustrated in elevation and attached to the handles of the stock. Fig. 2 is a sectional view taken in the plane indicated by the dotted line m a: on Fig. 1. Fig. 3 is a side elevation, partly broken away, of my improved device in a modified construction; and Fig. at is a sectional view taken in the plane indicated by the dotted line yy on Fig. 3.
Referring by letter to said drawings, Aindicates the stock and a the die, such as commonly used for forming an external thread on gas and other pipes, the handles 1) being partly broken away. The stock and die which I have shown form in themselves no part of my invention and may be of any ordinary or approved pattern, the one which I have illustrated being simply for the purpose of showing one manner of applying my improvements and a mode of operating the same.
B indicates the frame or knife-holder of my improved device, which is here shown as of a bowed or curvilinear form in outline, having a transverse eye 0 at each end to receive the handles 1) of the stock, and each apertured end is screw-tapped, as shown at d, to receive a bolt or screw e, which is designed to enter the eyes or apertures c and firmly impinge upon the arms I), so as to secure the frame or holder in proper position with respect to the die and pipe to be operated upon. In
the construction of stock illustrated the handles are screwed into sockets, and such construction will be found very convenient in applying the frame or holder here shown, as it is simply necessary to screw oif the handles and after inserting them in the eyes a of theframe or holder to screw said handles back again in the sockets of the stock. In this way my improved device can be easily and readily applied tosuch pipe-threaders as are at present in use without altering their construction in any manner whatever.
The frame or holder D is provided at a point coincident with the center of the threadingdie with a knife or reamer seat f. This seat may be formed by slotting said frame or holder transversely and preferably in an angular manner, the seat which I have shown being of an elongated rectangular form in crossseotion. The slotted portion, as more fully shown in Fig. 2 of the drawings, is provided with a screw-tapped aperture g to receive a screw h, which screw is designed to impinge against the shank of the reamer or cutter blade and secure the same in its seat, while in Fig. 4 of the drawings I have shown the screw h as taking through a slot in the shank of the cutter and provided with a shoulder i to bear against said cutter and confine it in its seat. In the construction shown in Fig. 2 I have provided the screw with a handle j, while in the construction shown in Fig. 4 I have provided the screw with wings but even these means for securing the cutter in its seat I do not wish to confine myself to.
0 indicates the reamer or cutter. This reamer is composed of a piece of steel of suitable length and thickness and is tapered for a sufficient length on opposite edges to one end so as to form cutters m, and forconvenience in operation the shank of the blade is provided with graduations, as shown at n. By the provision of these graduations the cutter, which is slidable in its seat, may be adjusted according to the size or diameter of the pipe upon which the thread is to be formed. I have shown the scale as running from one inch to one-fourth of an inch; but it is obbrought in contact with the bur in the pipe until the threading-die has advanced sufficiently on the outside to have the said blade finish removing the bur simultaneously, or approximately so, with the finishing of the thread. In this way but a single operation is required to thread a pipe and remove the bur from the interior, which was formed by the operation of cutting the pipe into lengths.
As shown, the reaming-blade C is beveled to ream when the die is cutting a left-hand thread. It is obvious, however, that the blade may be beveled to ream incident to the cutting of either a right-hand thread or a lefthand thread, as desired.
The reaming or cutting blade, as shown in Fig. 1 of the drawings, has its shank plain, while in the construction shown in Fig. 3 I provide the shank of the blade with a longitudinal slot 1), in one case it being necessary to have the securing-screw take through the slot,while in the other case the screw impinges against the plain side of the blade.
I do not wish to be understood as limiting myself to any particular means of securing the blade to its holder; nor do I wish to 0011- fine myself to having the reaming tool or blade provided with two cutting edges, for although it is preferable to have two yet in some cases but one might be used.
In operation the knife or cutter is first adjusted according to the diameter of the pipe to be threaded, which is indicated on the shank of the cutter. The screw is then turned up, so as to secure the cutter in its seat, after which the handles of the stock may be grasped and operated in the usual manner to form a thread, it being unnecessary to pay any furiherattention to the reamer. As the threader has advanced sufficiently the reamer will be brought into action, and by the time the thread has been finished the bur will be removed with but very little exertion from the operator more than what is necessary to cut the thread.
Having thus described my invention, what I claim is- 1. The combination of a pipe-threading diestock having handles at opposite points, a bowed frame straddling the stock and hearing on the handles thereof and having an opening coincident with the die-opening, devices for detachably fixing the ends of the frame on the handles of the stock, a cutter arranged in the opening of the frame, and means for securing the cutter in the said opening, substantially as specified.
2. The combination with a pipe-threading die-stock and handles detachably connected thereto at opposite points; of a bowed frame straddling the stock and having eyes receiving the handles thereof and also having an opening coincident with the die-opening, setserews bearing in the-walls of the eyes and arranged to impinge against the handles, a cutter arranged in the opening of the frame, and means for securing the cutter in the said openings, substantially as specified.
3. The herein-described attachment for pi pe-thrcadi n g die-stocks,comprisi n g a bowed frame arranged to hear at its ends on the handles of a die-stock and having means for detachably fixing such ends to the handles and also having a central opening, a reaming-cutter arranged in said opening, and having a tapered end, and a binding-screw carried by the frame and arranged to impinge against said cutter, substantially as specified.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
JOHN B. KAISER.
