GEORGE REEB, OF PITTSBURG, PENNSYLVANIA BEAT/[ER ATTACHIVIENT FOR DIE-STOCKS.
T 0 all whom it may concern:
Be it known that I, GEORGE REEB, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Reamer Attachments for Die-Stocks, of which the following is a specification.
This invention provides an attachment for application to die stocks for removing the internal bur of pipe or tubing simultaneously with the operation of threading, the attachment being of such structure as to be readily applied to the die stock or removed therefrom when not required for immediate use.
The invention has for its object to combine with the frame of the attachment and holder for the cutter novel means for positioning the cutter and securing the same in the lo cated position, the parts being constructed with reference to simplicity and durability as well as efiiciency in operation.
The invention consists of the novel features, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.
Referring to the drawings, forming a part of the specification, Figure 1 is a top plan view of a die stock provided with a reamer attachment embodying the invention. Fig. 2 is a plan view of the frame of the attach ment as seen from the inner side. Fig. 3 is a perspective view of the cap for retaining the feed nut in place upon the frame. Fig. 1 is a central longitudinal section of the die stock and attachment, the outer portions of the handle receiving sockets being in full. Fig. 5 is a transverse section on the line 5-5 of Fig. 1.
Corresponding and like parts are referred to in the following descrlption, and indicated in all the views of the drawings, by the same reference characters.
The die stock 1 may be of any construction, make, or design and adapted to receive the usual dies for threading pipe or tubing. Set screws 2 and 3 are provided at diagonally opposite points of the die stock, as indicated most clearly in Fig. 1, and are intended to serve as securing means for fastening the attachment to the die stock. One of the set screws, as 2, may have its head slotted to receive the point of a screw driver,

whereas the set screw 8 is provided with a thumb piece to admit of its manipulation by hand.
The attachment comprises a frame at formed with opposite extensions 5, in which open ended slots 6 are formed to receive the set screws 2 and 3. The slots 6 face in opposite directions and extend laterally with reference to the parts 5, whereby the frame when placed upon the body of the die stock may be engaged with or disengaged from the set screws by a partial rotary movement. A slot 7 is formed in the frame l and receives a pendent portion 8 of the holder 9. A transverse slot 10 intersects the longitudinal slot 7 and is adapted to receive the feed nut 11. Depressions 12 are formed at opposite sides of the transverse slot 10 and serve to receive journals 13 of the feed nut 11.
The holder 9 is formed with a pendent portion 8 and a threaded stem 14:, the latter passing through the feed nut and cooperat ing therewith. The body portion of the holder rests upon the frame 4: and overlaps the parts bordering upon the slots 7, whereas the pendent portion 8 extends into the slot 7 and is adapted to move therein. An opening extends through the body of the holder and the pendent portion 8 and receives the cutter. The threaded stem 14 engages a correspondingly threaded opening of the feed nut 11 and when the latter is rotated the holder is moved upon the frame to adjust the cutter relatively to the size of the pipe or tube to be reamed or operated upon to remove the internal bur or otherwise enlarge the opening in the end thereof.
A cap 15 is secured to an end of the frame t by means of screws or like fastenings 16. Lugs 17 at one end of the cap enter openings 18 in the frame and supplement the action of the fastening 16 to prevent displacement of the cap and to relieve the fastenings'lti in a great measure of the strain coming thereon. The cap is formed with a transverse slot 19 to receive a portion of the feed nut and depressions 20 are formed upon opposite sides of the slot 19 and cooperate with the depressions 12 of the frame to form hearings in which the journals 13 of the feed nut are mounted.
The cutter 21 has a shank, which passes through the opening of the holder and pendent portion 8 thereof, said shank comprising a threaded stem 22 and a wedge portion 23. A set nut 24 mounted upon the threaded stem of the cutter is adapted to secure the latter to the holder by drawing the wedge portion 23 of the shank into a correspondingly formed portion of the opening provided in the pendent part 8 of the holder.
It will be understood that the reamer attachment may be used both in connection with the threading dies or without, as may be required, and that when it is not desired to ream or enlarge the opening of a pipe when threading the same, the attachment may be removed, the construction being such as to admit of this result being quickly effected, it being necessary only to loosen the set screws 2 and 3 and to give theframe 4 a partial turn, so as to disconnect the frame from the set screws. The reverse of this operation enables the attachment to be quickly placed in position when required.
From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claim appended hereto.
The cutter 21 may be properly set to the size of the pipe to be reamed, this being effected by means of graduations provided upon the frame 4, as indicated most clearly in Fig. 2.
Having thus described the invention what is claimed as new, is
A reamer attachment for die stocks comprising a frame having a slot, a cutter adapted to operate in the slot of the frame,
a holder for the cutter slidably mounted upon the frame and having a threaded stem, a feed nut mounted upon the threaded stem of the holder and arranged upon the frame, and a cap secured to the frame and adapted to retain the feed nut in place thereon.
In testimony whereof I affix my signature in presence of two witnesses.
