BEADING-TOOL FOR BOILER-TUBES.

Specification of Letters Patent.

Application led .Tune 1, 1910. Serial No. 564,413.

To all 'whom 'it may concern:

Be it known that I, EUGENE Win'r, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Beading-Tools for Boiler-Tubes, of which the following is a specication.

This invention relates to a beading tool and particularly pertains to a tool for expanding and beading the ends of boiler tubes in the end plates or tube sheets of locomotive boilers and the like.

In the ordinary construction of boilers, the ends of the boiler tubes are inserted in holes punched in the tube sheet and are fastened therein by expanding the tube in the perforation and then beading the end of the tube over the face of the tube sheet so as to cover the joint and strengthen the connection. Usually two separate tools are employed in making this connection; one for expanding the tube and the other for forming the bead.

It is the object of this invention to provide a tool by means of which both the expanding and beading functions can be performed in one operation, and by means of which better work can be done in less time than with separate tools.

Another object is to provide a multiple beading tool which is especially applicable for use in repairing imperfect connections between the tubes and tube sheets, in locomotive boilers, and which is so constructed as to expand and bead the end of the tube at the same time, thus insuring a perfectly tight joint.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is an elevational view of the invention. Fig. 2 is a plan view. Fig. 3 is a vertical section on the line X X Fig. 2. Fig. A is a cross-section on the line Y Y Fig. 1.

In the drawings A represents the tubular handle or hollow shank of the tool thro-ugh which a loose stem or impact tappet member 2 extends. The outer end of the stem 2 is adapted to be inserted in a pneumatic hammer of any suitable type which imparts successive hammering blows to the stem 2 to operate the tool as later described. The inner end of the stem 2 is slightly enlarged at 2 and rests against a metallic disk or anvil 3 loosely mounted in an enlarged head or housing A formed on and integral with the shank A. The anvil 3 in turn bears against the inner end of a toolholder t also mounted and guided in the enlarged head A. This tool-holder 4 extends beyond the head A and is retained therein by means of helical springs 5. The upper and lower ends of each spring 5 are connected to respective eye-members 7*7; the eyes 7 on the upper ends of the springs 5 being strung on a wire ring 9 which encircles the shank A and rests in a groove in the shoulder formed at the juncture of the shank A with the enlarged head A. The eyes 7 on t-he lower ends of the springs 5 are slipped over and hooked on pins or lugs 10 mounted on the tool-holder 4c, the lugs 10 being notched on their under side to have a removable hooked engagement with the eyes 7. The springs 5 are of such tension as to normally retain the tool-holder 4 in its innermost position in the head A and against the anvil 3 which is interposed between it and the stem or impact member 2; at the same time the tool-holder 4L has a limited lengthwise movement in the head when struck a blow by the stem 2 and anvil 3. The head 4: is provided with a plurality of longitudinally extending radial slots 11, in each of which a beading and expanding member 12 is pivotally mounted; lugs 13 on each side of the upper end of a member 12 resting on shoulders formed in the toolholder A at the upper ends of the slots 11. The members 12 are supported directly against the anvil 3. The lower end of each member 12 is fashioned with an outwardly and backwardly curved wedge surface 14 leading into a groove or recess 15, corresponding to the required shape of the bead to be formed. The surface 14: from the lower point of the member 12 is curved outwardly in such manner as to contact with the inner wall of a boiler tube when the tool is inserted therein; the member 12 being Patented Mar. 28, 1911.

pressed into slots 11 and against springs 1G.

The springsl are mounted in the slots 11 and tend to pushvthe expanders and beaders 12, so they stand at an angle to the longitudinal aXis of the tool'with the groove 115 more remote from the axis than the pivotal points 13. r1he head A isradially slotted at 17 to permit of movement of the members 12and is sletted'lengthwise at 18 for` factorily as shown. When the parts are assembled, as shown in Fig. 1, the tool-holder Ll isyieldingly held in the head A, so asfto have a limitedmovement lengthwise thereof, and the several headers 12 are disposed in distended position under the action of their springs 16 with the cam surfaces 14- an'd' beadingv grooves 15 projected beyond thev peripheryT of the tool-holder.

In operation, assuming a tube to be `inserted through a tube sheet, the tool-holder l isplacedin the open end ofthe boiler tube with the beading recesses 15 of the members 12 restinlg'upon the-end of the tube; the bowed extension 14 being pressed inward andlcontacting with the inner wall of the tube a distance equal to or a little greater thani the thickness ofthe tube sheet ofthe boiler. A pneumatic hammer being connected to the stem 2 and set in operation, rapidiimpulsive blows are delivered on the latterwhich are imparted through the stem 2 and theanvil 3 tothe inner end of the tool-holder e' and to the upper ends of the beading members 12. rlhe force of each blow causesthe members 12Jto move lengthwise and outward at'the same time, by reason of the angular relation between the point of the delivered force `andthe point of con* tactwith the tube, thus causing the tube to beexpanded by the lateral impact of the curved'extensions 1d andbeading the end of thetube by the longitudinal impact of thewalls of the grooves 15. The beading and expanding of the tube, occasioned simultaneously as it is, insures a thoroughly tight contact or joint being made between the tube and the' tube sheet. By turning the tool one-third of a revolution back and forth fromone side to the other, by means ofthe shank or handle A, the entire circumference of the end of the tube will be acted upon by the members 12. The tool-holder l is caused to turnfwit-h the handle A by reason of the members 12 extending through therslots 17 in the head A', and is caused to return `to its innermost position in the head after each blow of the hammer piston by meansof the springs 5.

The members 12 may be readily removed and replaced by disengaging the plates 7 on the lower ends of the springs 5 from the pins 10," whereupon the tool-holder t can be lifted `out of the head A and access given to the members 12.

One important feature is that no screws or screw pai-tsar@ employed.

ln repairing leaking tube plates in locomotiveboi-lers it has been found that` this device will enable a workman to do better and more eflicient work than with the single beading tool now generally in use, in considerably less time, and without appreciable injury to the tube plate.

The multiple tool principle embodiedin thisV invention insures a uniform' standard of beading, especially in repair work, and does not require the skillin operating necessary in doing the'work witha single tool.

Having thus described my inventiomwhat l' claim and desire to secure by-Letters Patent is- 1. Ainultiple beadingtool, comprising'a tool holder and a suitable support; therefor, means holding the tool holder to the support while allowing it to yield Vlongitudinally thereof,` a series of radially movable headers mounted in said yieldable holder, and means for imparting a series of blowsthrough the tool holder simultaneously to all the said beaders.

2. A beading tool consisting of a head, housing an anvil memberfand a tappet member bearing on the anvil, a tool-holderyieldingly held in the head, and Ya `series 1 of lengthwise extending, circumferentially disposed, movable beading members on said tool-holder receiving the impact of said anvil.

3. A beading tool consisting of a head having a hollow shank, impulsedelivering means housed in said head and shank, a longitudinally yieldable tool-holder in the head, and a beading tool carried by and extendingk lengthwiseofthe tool-holder and having alyieldin'g, radial movement.
