SPECIFICATION forming part of Letters Patent No. 299,997, dated June 10. 1884.

Application filed November' 17, 188i. (No model.)

To @ZZ whom, t may concern:

Be it known that I, MATTHEW R. Moonn, of the city of Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Machine for Flanging Heads for Steamdoilers; and I do hereby declare that the following specification, together withV the accompanying drawings, which are attached to and made part thereof', is such a full, clear, and exact description of said machine `and its mode of operation, as will enable any ,the sheets which compose the shells of the boilers are riveted. This operation, as usually performed by hand, involves the expenditure of much time and severe manual labor, and many attempts have been made to adapt machinery to the work so as to diminish such eX- pense,but hitherto without entire success. To accomplish the object sought and avoid the difficulties hitherto encountered,I have 'devised the machine whose construction and operation will be made plain by the following description.'

Figure l is an elevation, partly iri section. Fig. 2 is a top plan view. Fig. 3 is a detail perspective of one of the hooks. Fig. 4E is a plan view showing` particularly the operation of the centering devices. Fig. 5 is a vertical section of the saine, with portions in elevation and Fig. 6 is a modification showing a means for beveling. Fig; 7 is an enlarged elevation, showing particularly the arrangement of lthe locking-piece and its flanging-roller in their relation to the former and to the operating means.

Referring to the drawings, A designates a strong framing, carrying in suitable bearings an upright shaft or arbor, B, to which rotary motion may be imparted through gearing, as shown, or by other proper means. per end of this arbor is fitted to receive a oircular former, O, which is so arranged as to be readily removable and others of different sizes substituted,as the dimensions ofthe work may The up-- l require. Directly over the center of arbor B is supported in a substantial manner another arbor, D, which does not revolve, but may be raised and lowered by means of the screw and hand-wheel E. A platen or follower, F, similar to the former C, but smaller, is attached to the bottom of arbor D in a readily-detachable way, so that other sizes may be substituted, as required. Between this follower F and the former O the sheet to be flanged is gripped by the action of the screw E, and `receives rotary motion through arbor B. As the follower F must revolve, while D is stationary, a joint, G, is provided to enable it to do so, and as the sheet operated upon may not be straight or true,

joint Gis made universal or of ballandsocket form, so that F may accommodate itself to such irregularities and hold firmly. Arbor D is prevented from revolving by a feather in the supportingbracket, so that the revolution of F may not operate the screw E. vThree hooks, F', one of which is shown in detail, Fig. 8, are pivoted to the follower F. When not in use, they are folded back upon the top of the follower, but may be turned down so as to catch the edge of theflange when formed. Attached to the frame A in such a way as to be adjustable toward and from arbor B is a strong post or stanchion, H, which bearsthe vertically-sliding part I, which is adjustable upward and downward by means of the setscrews shown. In the face of I are formed circular bearings which support the rocking piece K, which is capable of making therein a little more than one-quarter of a revolution. Upon each end of this rocking piece are toothed segments, which gear with pinions Z on the shaft of hand-wheel L, whereby the motion of the rocking piece K is produced.

Upon a strong stud in the rocking piece is carried a cylindrical roller, m, which, as its duty is to bend over the edgeof the head into a flange, is called the flanging roll.77 The arrangement is such that while the flangingroll is capable of revolving freely upon its stud it maybe borne round by the rocking piece from a horizontal position at right angles with the arbor B through a circular path about a point corresponding to the center o f the bend or corner of the flange produced, to a vertical position parallel with arbor'B. The machine is to be so set that the greater part of arbor B and the gearing which gives it motion is out of the way beneath the hoor, the hoor-line corresponding with N N, the plane whereon the post H is adjustably hxed.

The description thus far includes all the parts which are essential for hanging circular boiler and steam domeheads, and may be used without any further additions; but the machine is made more convenient to operate and its usefulness increased by the several appliances hereinafter described. A means of quickly centering the head to be hanged upon the former C is very desirable. A device for this purpose is shown in the drawings, Figs. 1 and 2, and more clearly in detail, Figs. 4L and 5.

It consists of two shafts, O O, carrying two toes each,-P P I? I?,which are adjustable lengthwise on the shafts andhave rollers on their ends. The shafts are connected together by means of the shaft and bevel-gears Q Q, and operated by lever It. The toes, except when in use, lie hat upon the hoor, out of the way; but as the shafts are turned by the lever toward the center of the machine the toes rise, and will carry a head before them until it is held between their ends over the center of the former C, where it is secured, and they are turned back out of the way again.

The 'operation of hanging a boiler-head may nowbe described as follows: Aformer of suit-- able'size for the head to be hanged is placed upon arbor B, and a follower about two inches less in diameter is secured to arbor D. The former and follower are precisely alike, eX- ceptin size, so that the former for one sized head may be used as the follower for the next larger size. The hanging-roll m is brought,

by means of the adjustments ofpo'st H and slide I, to such a position that its lower side when horizontal will be a little more than the thickness of the metal to be hanged above the surface of the former C, and the same distance away-from the edge 0f the former when vertical. Allowance is made for the thickening of the edge of the head through upsetting the flange. rI`he hanging-rollbeing in its horizontal position, and the follower raised a suhicient distance above the former C, a head to be hanged is heated in a furnace constructed for the purpose to a bright red heat, then laid upon former C, centered by operating-lever R,'and firmly secured by bringing the follower F down upon it by means of the screw and hand-wheel E. Power is thenappliefhand the operative,by turning the hand-wheel L, causes the hanging-roll to bear upon the projecting edge of the revolving sheet and carry it downward until it is shaped into a hange between the hanging-roll and the edge of the former, and stands at a right angle with the rest of the sheet. The motion is then stopped, the follower-hooks turned down to catch under the edge of the flange, and the followerbacked off by operating the screw E, pulling from the former the hanged head, which may be carried away to cool, while the machine is made ready for the next one.

Y piece from the former.

It is often desirable to bevel the edge of a hanged head to facilitate calkingdown after riveting it into the boiler. For this purpose a tool-post is substituted for the hanging-roll, and the head centered and clamped in the machine with its flange uppermost, when the edge of the flange may be beveled in a manner so clearly shown in Fig. 6 as to need no further description.

To adapt this machineY to the hanging of heads of other than circular shapes-as for locomotive hre-boXes-the arrangement shown in Fig. 7 is used. A former of less radius than the smallest curve inthe contour of the proposed head is placed upon the`arbor B. A guide-piece, S, is fastened to I a distance equal to the height of the proposed hange from the edge of the former, and the angular attachment and beveled roller U substituted for joint G and follower F. The beveled roller must be so placed that when lowered upon C their line of contact will be exactly opposite the center of the hanging-roll. A-table, T, is provided to supportthe heated sheet to be hanged, which being placed thereon and its edge pressed against the guide-pieces and gripped between roller U and former C, and the machine put in motion, the hanging-roll turns the flange in a similar way, as in the lprocess before described. The tendency to rotate about the axis of B imparted to the sheet keeps its edge always in contact with the guide-piece, which prevents it going any farther than sufficient to form the flange, so that the sheet is carried along by the former and rolls, and its whole edge, whether curved or straight, is -turned down into a flange whose depth is governed by the distance ofthe guide- It is necessary, in this process, that the edge of the sheet be smoothly trimmed to the proper size, as it forms the guide in hanging, and any irregularities in it will affect the hnished-head. If this precaution be taken, it is practicable tov flange by this process circular heads of various sizes without change of formers. sired to form flanges which do not go completely round the sheet, as in half-heads and throat-sheets, a reversing motion must be provided for arbor B by means of open and crossed belts or other convenient appliance, so that the sheet may be traversed forward and back until hanged. This means Afor hanging heads not circular will be made the subject of a separate applicatiom'the figure in this application being designed to show the arrangement of the roller m, the rocking piece K, the sliding frame I, e., in their relation to the former C.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

I. In a hangingmachine, substantially as described, a revolving former mounted on an arbor, as B, a clamping-follower having anniversal joint to accommodate inequalities in the sheet to be acted upon, and a hangingroller, m, with means, as the devices indi- IIO Vhen it is decatedby K I L, for changing it from a horil zontal to a vertical position in proximity to the edge of the former, all combined and operating substantially as and for the purposes set forth.

2. In combination with the arbors B and D andwith interchangeable formers C, the follower F, having a universal joint with D, to accommodate inequalities in the sheet to be acted upon, the hand-wheel E, toothed rocking piece K, carrying roller m and pinion Z, and handwheel L, as and for the purposes set forth.

3. In combination with the arbor B, carrying a former, C, a centering device composed of adjustable arms, and suitable mechanical connections controlled by a lever for operating inward simultaneously to bring the said arms against the blank to be centered upon the former, as set forth.

4. The arms I?, having anti-friction rollers,

in combination with means, as the devices indicated by O Q R, for operating said arms simultaneously and equally, and with the arbor l ranged and operating as and for the purposes @L set forth.

5. In combination with the former C, post H, sliding piece I, and toothed rocking piece K, the Hanging-roller m, hung upon a stud rigid with said piece K, and means, as pinions Z and hand-wheel L, for moving said roller at will, as set forth.

6.' In combination with the follower F, as desoribed,.the pivoted hooks F', adapted by their gravity to lie back upon the follower, or to fall under the flange of the finished head to remove the same from the former, as specified.
