To LLZZ whom) tm/ay concern.-

at Sandwich, in the cou'n'ty of De Kalb and State of Illinois, have invented certain new and useful Improvements in Beamers, of ywhich the following is a specification.

IMy invention relates to certain improve-y ments in rearners designed especially for. use

1o in removing the inwardly-pressed bur commonly producedv by ordinary tools used for cutting off wrought-iron gas, water, andV steam pipes. In cutting od the smaller sizes of these pipes, such as are more commonly used, a rotary tool of some sort is usuallyem-- pleyed, the .action of which is to crowd the metal inward toward the center-of the ,pipe

and when said metalis nally severed to leave' a very pronounced burfor inwardly-projectzo ing ange, which reducesthediameter of the pipe and is other'vviseexceedingly.objection-v able.V It is my purpose to provide acheap and reliable device which maybe accurately centered upon the end of a pipe of.. this' sort and positively advanced Yinto the same to make a clean cut suici'ent to remove all of the bur above described; and to such end the invention consists in certain features of novelty below described and claimed.

In the drawings presented herewith, Figure l is a side elevation showing the reamer secured to the end of a piece of pipe. Fig. 2 is a vertical longitudinal section of the same, the line of'section being shown at 22'of Fig.

' 3 5 3. Fig. k3 is an end elevation of said device.

Fig. 4 is a detail section in plane 4 4; ofV Fig. 2, looking in thedirection ofthe arrow 4. Fig. 5 is a similar section in line 5-5 of 1'Fig..4, looking in the directionof the'arrow 5. Fig

4o 6 is a perspective of adetachable plate. Fig.` 7 is a perspective of a tool-carrier. Fig. 8 i-sl a perspective of a bearing-cup. Fig. 9 is a section in line 9 9'ofFig. l. Fig. 10 isa section in line l0 10 of Fig. 1, and Fig. 11 is a view similar to Fig.r3 with all ,of the parts down tothe covering-plate removed.

Referring first to Figs. 1 and 2, apiece of gas-pipe is shown at A, upon which is secured a detachable collar B by means of set-screws 5o b b' 1 1?, an intermediate perforated bushing .annular ange.

n b3 beingshown in Fig. 2 to 'accommodate the Be it known that I, WILLIAM RADLEY, a citi zen of theUnited States of America, residing` pipe A, which is smaller than the smallest 'size which the collar will hold.L The removable collar is internally screw-threaded at b4 to receive an externally-screw-threaded collar C, the threads c of which fit those of the .removable collar, so that the rotation of the collar C advances it upon or withdraws it from the end of the pipe. This collar C will be called the feed-collar and the screw-threads c thereon the lead-screw. The feed-coliar C isprovided with'a radially-projecting annular flange c', toothed around its outer margin Aat c2., Against one side of the iange c rests a plate-like extension d upon ahandleD, pivoted upon the feed-collar by means of said extension. It is secured in this position by means-of two clips ci'dfl, which project inward slightly over the opposite side of the Between the clip d2 and the plated is'pivoted a'detent or pawl d3, (shown `moreclearly in Fig. 3,) one end of which, (Z4, A'is heldin engagement with thetooth of the lian ge by a spring d5 and the other end of which is formed into a handle-d6. By means of the 'handle D and detent the feed-collar may be rotated to advance or Withdraw it from the removable collar B. The annular flange c is provided with a series of studs c3, upon the ends of which is removably secured a perforated plate E by means of screws e.

The parts above referredv to make up an Figs'. 10 and 11, said Fig-ll also showingone of a series yot rectangular bushings Y, by

rmeans of which difterent sizes of dies may be accommodated. VThe die is secured inthe :stock by means of the perforated plate E above mentioned. This plate E is shown in perspective in Fig. 5. It is provided Lwith a 'central-o eninfJr c' about the margin of which D e a e are two hooked lugs c2, the inner surfaces of the hooks of. which are inclined, as seen at e3.

ordinary die-stock, and so far as they have Upon this plateis removably secured a bearing-cup F. (Shown in perspective in Fig. S and in4 various sections in Figs, 2, 4,75, and 10.) Upon the insidepf the rimof thecup are two roo e eaav inwardly-projecting lugsff, adapted to engage with the hooked lugs e2 and Wedge themselves between the hooks upon the latter and the plate E to firmly secure the bearingcup to the plate. The cup is provided with a handle f2, by means of which this attachment may be effected. It also has a central perforation f3 in its bottom portion, in which is j ournaled a tool-carrier G. (Shown in perspective in Fig. 7.) This tool-carrier has a cylindrical portion glitted to the perforation f3 in the cup, a notched flange g upon one side of said cylindrical portion, adapted to rest upon the inside of the bottom of the cup, and a flat extension g2 upon the other side of said cylindrical portiomprovided Witha slit g3 to accom- Inodate a suitable reaming-tool. Upon this fiat extension is secured a handle H, (see Figs. 1,-2, and 3,) provided, with a slot h to fit over said extension and secured thereon by means of a split pin h,Which also secures the reamer in the slit. `Said reamer is seen at l and has an inwardly-extending tapered and sharpened end t' to do the cutting and a series of perforations i to receive the pin h' and enable the reamer to be secured in a number of predetermined positions.

Fig. 9 shows an auxiliary device adapted to hold a wrench such as is needed in the4 use of the die-stock,the same consisting of a lug s, projecting from the handle, and a button SQ pivoted upon the lug. The lugis so proportioned in cross-section as to fit one of the openings of the Wrench, and the button is adapted to secure the Wrench upon the lug. This device aords a means of insuring the presence of the Wrench Whenever needed and avoiding ythe possibility of losing the same.

In the operation of the device above ldescribed the die-stock is secured to the pipe, and the reaming device is fastened upon the end of the stock by means of the bearing-cup F. The handle H is then turned to rotate the reamin g-tool and the handle D oscillated to advance the feed step by step and carry the ream erinto the end of the pipe. While of course the reaming operation may be effected Without regard to the threading of a pipe, yet Iconsider my invention particularly valuable because of the possibility of carrying on the two operations simultaneously, or at leastin succession, Without removing the die-stock from the pipe. They preferred method is to secure the die-stock upon the pipe with the die in place and the reaming-tool attached and so adjusted as to finish its cutting when the die has completed the threading operation. The die-stock is then rotated to thread the pipe, the feeding devices being loosened upon said pipe as soon as the die takes a proper hold and the reamer being rotated by means of the handle H as soon as it comes in contact with the bur extending into the pipe. By this means the reaming is effected Without any expenditure of time and with but little additional effort beyond that required to thread the pipe.

I claim as new and desire to secure by Letters Patentl.
