Application filed August 1', 1914. Serial No. 854,990.
To all whom it may concern:
'Be it known that I, WALTER S. DONALD- son, a citizen of the United States, residing at Umaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Reamer Attachments for Die-Stocks; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to reamer attachments for pipe-cutting die-stocks, and has for its object to provide a device of this character of improved and simplified construction, which may be quickly and conveniently attached to several of the stand ard forms of die-stocks.
With this and other objects in view, the invention consists in the novel construction, arrangement and the formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawings, in which,
Figure 1 represents a side elevation of the attachment applied to a die-stock of a standard ty e, Fig. 2 represents a sectional view therethrough, partly broken away, Fig. 3 represents a side elevation of the reamer removed, Fig. i represents a transverse sectional view on the line H at Fig. 3, Fig. 5 represents a top plan View of the reamer, partly broken away, Fig. 6 represents a transverse sectional view on the line 6-6 of Fig. 1-, and, Fig. 7 represents an enlarged detail view, partly broken away, of the reamer and holder therefor.
Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 10 indicates the body of a die-stock of standard construction provided with the usual handles ll, the dies 12 and the throat 13.
A plate 14c is secured to the top face of the body 10 by suitable bolts 15 and is provided with a right angularly extending hollow barrel 16 having an inwardly directed flange 17 at its upper end and an open lower end. The bore 18 of the barrel 16 is rectilinear and the inwardly directed flange 17 is provided with screwthreads to receive the sleeve 19 having a circular bore receiving the shank 20 of the holder 21. A threaded cap 22 is fitted on the upper end of the sleeve 19 and a nut 23 is fitted on the upper extremity of the shank 20 for ad ustably securing the latter. An expansion spring 24 is coiled about the shank 20 and engaged at its opposite extremities against the cap 22 and the enlargement constituting a part of the holder 21 which latter is of rectilinear formation and rotatably and slidably mounted in the rectilinear bore 18 of the barrel 16.
The reamer 25, preferably of the rose type is positioned within the concaved end of the holder 21 and is provided with a shank 25 positioned within a recess 27 in the holder and secured against removal by a tapered pin.
In operation, the sleeve 19 is adjusted relative to the barrel 16 to engage the reamer 25 within the end of the pipe 28, and the vreamer, as it will be understood, is resiliently retained in operative position against theend of the pipe by the tension of the spring 24: which may be adjusted by the nut 23.
What I claim is:
1. in combination, a barrel having a rectilinear bore and an inwardly directed flange at one end providing a circular opening having screw threads, a sleeve ad ustably positioned within said threaded opening, a holder positioned within said sleeve, a .reamer in said holder, and means for resiliently retaining said holder in extended position.
2. In combination, a barrel having a rectilinear bore and a threaded aperture in one end, a sleeve adjustably positioned in said aperture, a holder of rectilinear formation slidable and non-rotatably mounted in said bore, a shank on said holder extending exteriorly of the upper end of said sleeve,,
means for normally retaining said holder in downwardly extended position, means carried by the upper end of said shank for limiting the downward movement thereof,
and a reamer secured in said holder.
3. ln combination, a barrel having a rectilinear bore and a threaded aperture in one end, a holder of rectilinear formation non-rotatably and slidably mounted in said rectilinear bore, a sleeve fitted in said In testimony whereof I aiiix my signal thregded apertuge, in a aertured cap seized ture in presence of two Witnesses.
at t e upper en 0 sai s eeve a she on said holder projecting through said cap, a WALTER DOSALDSON' nut on the upper extremity of said shank, Witnesses:
\ and a spring disposed between said shank HENRY W. Mum,
and said holder. LUDWIG KREGER.
