To @ZZ whom it may concern:

Se it known that I, WILSON F. HUTcHIsoN, a citizen ofthe United States, residing at Sherman,'in the cpunty of Graysouand State of Texas, have invented a new and useful Flue- Beader, of which the following is a specification.

This invention relates to means for beading, swaging, or upsetting the ends of boiler flues or tubes after the latter have been placed in position in the boiler-heads, so as to secure a steametight joint, a neat iinish, and a substantial connection.

The' object of `the invention is tol provide a 'tool which can be rotated and Will successively and gradually turn the projecting end ot the tube or iiue without unnecessarily straining or disturbing the fibers of the tube to Such an extent as to create fracture or weaken the beaded end.

A further purpose of the invention is the construction of a tool which While being rota ted can be forcibly and positively advanced Setting of the flue or tube without requiring any special effort on the part of the Work man taller than that necessary to rotate the tool, so as to attain the object in view.

` With these and other objects in View, which will appear to one skilled inthe art `as the nature ofthe invention is uliderstood, the improvement consists of the novel features and combinations of t-he parts, which hereinafter will be vmore particularly set forth, illustrated, and finally embodied in the subjoined claims. The improvement is susceptible of various changes in the form proportion, and the minor details of construction without departin from the principle or sacriicing any ofthe advantages thereof, andto'a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in Which-- Figure 1 is a perspective view of a tool conbearings t being interposed between the shoulder 2 and head 3 to relieve the friction between -these parts when they are relatively turned. Theouter end of the ,head' is depressed, formiug two faces 5 and which stand at an angle relative to each other. A bead 7 is formed on the face 5 and a corresponding beadS is provided onthe face 6, and these beads 7 and 8 form annular tracks for calli-ing and swaging rollers to travel upon when the tool is in operation.

The sWaging-rollers 9 and the calking-rollvers 10 are similarly formed and .are alternately arranged, the sWaging-rollers 9 being placed to travel upon the face 5 and. track 7 and the calking-rollers 10 to operate upon the face 6 and track 8. Both sets of rollers have peripheral grooves intermediate of their ends which correspond to ltheforrn of the track against whichthe rollers bear, and these grooves are semicircnlar, or nearly so, to correspond to the beaded or upset end of the boiler. tube or tine. The swag-ing-rollers 9 start or give the initial bend to the projecting end of the flue or tube 11, and the calking-rollers givethe linishing turn tothe bead l2 and are formed with a cutting edge 13 to remove any surplus metal and to insure a iirin engagement between the bead 12 and the portion of the boiler-head 14 bordering upon the opening in which the fine or tube 11 is fitted.

A retainer 15 is rotatably mounted upon the outer end `of theshank 1, and its inner end is flanged, as Shown at 16, and is provided With a series of pockets or openings 17,

in which the several rollers are fitted and so asto `retain the rollers in place in theirpockets.

l he end of the Stem 1 opposite the shoulder 2 is threaded, as shown at 20, and `is adapted IOO , a screw-thread connection with the said rod by means of Ithe coupling 21. By turning the stockthe tool is advanced, thereby forcing and crilwding the rollers 9 and lO against the projecting end of the tube, said stock being turned in' any convenient Way, preferably by tting a rod in one of a series of openings 23, formed at intervals in the shoulder 2. After the rollers have' been'brought into forcible engagement with the projecting end of the iue the head 3 is rotated, thereby turning the vpro'j'ecting endA of the flue. After the head 3 has been rotated once or any required number of times thestock is again turned to advance the rollers to the work, thereby grad ually edecting the beading, it being remembered that. the head 3 is rot-ated between each successive advancement of thestock. The head is formed with a series of openings 24, which receive a rod or other implement, by means of which it is rotated, so as to edect ythe desired end. After the end is completely beaded the tool is removedand fitted to another fiue or tube andthe operation herein described repeated. v

` Having- 'thus described the invention, what is claimed as new isl. in a tool for beading boiler r'iues or tubes, the combination of a revolu bie head,and sWaging and calking rollers alternately arranged and disposed at different angles, whereby one set of rollers starts or gives the initial bend and the other set completes the beading or upsetting, substantially as specified..

2. In a tool for beading boiler tubes or flues, the V`Y`:embination of a revoluble head, swaging-.-.ollers disposed at intervals around the vrevdluble head. to start or give the initial bend to boiler-fiue,and calking-rollers arranged ii'il'erinediate of the swaging-rollers and at a diiierent angle thereto, and PlQvided with lcutting edges, substantially as and for the purpose set forth. 3. Inatool for beading boiler tubes or iiues, Y the combination of a revoluble head provided With oppositelyinelining` faces forming tracks, and rollers adapted to travel upon the said tracks, substantially as and for the purpose set forth. l A

4c. In a tool for beading boiler tubes or ues, the combination of a revoluble head having ppbsitely-inclining faces, each -formedwith a bead providing a'track, and rollers alternately arranged and disposed to travel upon the said tracks substantially as and for the. purpose set forth.

5. In a tool for beading boiler tubes or flues, the combination of a revoluble head, rollers" adapted to travelupon the revoluble head, and a retainer having openings to receive the' rollers and hold them in place, substantially asset forth.

6. In atool for beading boiler tubes'or flues, the combination of a revoluble head, rollers obtaining a bearing against the revoluble head., a retainer having openings foi-"receiving and securing the rollers in operative position, and a band secured to the retainer for holding the rollers in place, substantially as set forth.

7. The herein-described tool for beading boiler tubes or fines, Vconsisting of a stock h av-4 ing a shoulderand provided With-means tb positively advance it to the work, a head revo-` lubly mounted 11p-.initile stock and 'having opi positely-inclining faces provided with/annular. tracks, antif-riction-bearings between the revoluble head and shoulder, sv'vagingand calking rollers haring peripheral grooves which receive the' annular tracks and which effect the beading orupsetting of the flue-or tube, and a retainer formedwith a flange havf ing pockets or openings to receive .the afore;l v

- said rollers, substantially in the man-ner and for the purpose set forth.

` In testimony that I claim the foregoing as my own I have hereto affixed mysignature in the presence of two Witnesses.,

WILSON F. Murchison.
