To tf/Z whom, it may concern:

Be it known that 1, WILLIAM ENRIGHT, a citizen of the United States, residing at Detroit, county of Vayne, State of Michigan, have invented a certain new and useful lmprovement in Flanging-lVlachines; and l 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 pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to Hanging-machines, and has for its object an improved machine adapted to bend and stretch the metal and produce flanges on a large tube of metal.

In the construction of large tanks and standpipes and similar vessels that are intended to contain large quantities of liquids the structure is made in sections bolted together. It is desirable to prepare the metal sections of the tank with flanges that are bent outward or inward at the ends of each lcylindrical section and arranged so that contiguous sections may be secured together with rivets or bolts that pass through contiguous flanges; and the object of thisl invention is to produce an adlinstable machine capable of turning such flanges on cylinders or barrels of' different lengths and of different radii.

In its general features the machine comprises two rolls that act as a rolling vise or rolling holder for the metal that has been previously bent to tubular form. Provision is made to add to the rolls, so that a tubular body of any desired length within the capacity of the machine may be flanged. and the entire framework which supports the rolls must necessarily be adjusted to correspond with the length of' the selected roller. Provision is made also to support a sheet of metal bent in tubular form and to use tubes or barrels of different diameter with quite a large range of capacity, and provision is made to adinstand regulate the several working parts of the machine to perform their duties properly with any one of the selected sizes, either as to length or diameter.

In the drawings, Figure 1 is a plan view of part of the machine. 1n the view shown here the machine is shown as expanded to its full capacity and contains three auxiliary pair of vise-rolls in addition to the main pair of viserolls. Fig. 2 is a section of a tubular body with the flanges turned thereon. Fig. 3 is a plan view of the machine, showing' details of the main driving mechanism. (The beam companion to 21 isv omitted.) Fig. A is a plan view of a part of the inner frame. (The means for holding the two vise-rolls yieldingly together is here shown.) Fig. 5 is a longitudinal vertical section showing the stead y-arms by which the tubular body is held. Fig. 6 shows the parts connected with the arbor on which the Hanging-roll revolves. Figs. 7, 8, and 9 are details of parts. of the steady-arm shown in Fig. 12. Figs. 10. and lli' are details of the holding device shown in Fig. A. Figs. 12 and 13 are longitudinal sectional views showing in detail a stead y-arm, several of which are seen in end elevation in Fig. Figs. 14, 15, 16, 17, and 19 show details of several of the parts shown in Fig. 6, Fig. 18 is a horizontal section of the device by which the Hanging-roll is swung.

In the machine which embodies this invention there is an external framework. rI here are two rolls which are utilized to hold the shell or barrel of tubular metal that is under treatment. The two rolls will be hereinafter called the vise or the rolling vise.7 The `effective length of this vise may be varied by adding auxiliary rolls on the rollshafts. One of the roll-shafts is journaled at one end in the main frame, and the other end is journaled in a bearing that is slidingly supported in a bracket. The bracket is built out from thc main frame. rlhe other roll-shaft is supported at both ends in an auxiliary frame that has a sliding movement longitudinal of the main frame.

The main frame is made with two heavy built-up side frames, one of which, located at the rear of the machine, (the side which is shown at the top in Fig. 3 and shown in ele vation in Fig. 5,) is built of longitudinal stringers Q1, corner-posts 18 and 19, with suitable intermediate posts I7, and brace 16, bottomstringer 2, and horizontal intermediate stringere 2, The other side frame, at the front of the machine, is shorter, and the heavy top Stringer 21 is omitted from this front beam. The front beam carries one end of the shaft 14 and supports the ways for some of the adjustable parts which will be described, but does not support the heavier parts of the mechanism. The two side beams are secured together by suitable cross-bars A. The side beams support horizontal brackets 3", on which rest side beams 7l of an inner movable frame. The side beams 7l are connected by cross-beams 22 and 23 and cross-beams B and IOO IIO

C, all of which are provided with numerous bolt-holes and which hold securely the remaining parts which comprise the inner' frame, one part of which on the side R remains fixed in position with respect to side bar 71. The other part on the side L is shifted to bring this side of the inner frame to its proper place with reference to the number of auxiliary rolls that are in use.

Outside the main framework is the driving mechanism which communicates motion from any suitable source of power from drivingwheel 135, through clutch 35 on driving-shaft 34 and chain of gearing' from pinion 36, to gear 37 on the shaft 13 of roll 3. A gear 131 on the shaft 13 meshes with 'gear 141 on the shaft 14 of roll 4, and the power thus communicated to the machine drives the rolls 3 and 4in opposite directions. The other actuating mechanism of the machine may be manipulated or may be power-driven. It is shown in the drawings as hand-driven. One end of the shaft 13 is held in bearings in the right side beam, and to this right side beam is secured a bracket 11, which supports a sliding bearing 12, held in its selected position to the 'bracket by bolts. One end of the shaft 14 is held in bearings in the right side of the inner frame, and the other end is journaled in the sliding part of the inner" frame at the left end of the roll.

The cross-beams 22 and 23 and C and Bare provided with bolt-holes 24, through which pass the bolts which secure the inner frame together, and the length of each part of the rolling vise may be added to or diminished by using or laying' aside one or more of the auxiliary rolls, of which rolls 31, 32, and 33 are used on shaft 13 with roll 3, and rolls 41, 42, and 43 are used on shaft 14 ofroll 4.

The shaft 13, with the rolls mounted on it, is held in stable position. The shaft 14, with the rolls mounted upon it, is slightly movable with respect to the shaft 13 and is actuated by means of screws 51 and 52. (See Figs. 4, 10, and 11.) The stems of the screws 51 and 52 pass through bearings 3 in the cross-bar A, which is a cross-bar of the main frame, and the stemsare journaled in this cross-bar, and each is slightly movable along its own axis, but is normally held projected inward, bearing against the sliding inner frame by the tension of springs 54, each of which encircles the stem of its proper screw and each of which bears against the cross-bar A and the collar 53 on its proper screw. Each of the screws is provided with a sprocket-wheel 152, and the two sprocket-wheels are coupled by a chain 55, so that both the screws are actuated simultaneously by means of the handwheel 56.

The tubular body of metal on which the i'iange is turning' is placed between the rolls 3 and 4 of the rolling vise and rests on steadyarms that are held to the right frame-beam.

The inner surface of the tube engages against supporting- rolls 50, 60, 70, 30, and 90, which, with the brackets that support them, are adjustable to accommodate diierent sizes of tubes. The flanges are turned by rolls 61 and 62, which are similar in construction and similarly actuated. Both the Hanging-rolls are swung to allow the tubular body which is to be treated to be inserted between the rolls 3 and 4, and both have a horizontal movement radial with respect to the roll 4, which movement takes placeduring the progress of turning the flange. The rolls are actuated along this radial path as the anges are formed. The two movements will be best understood by examining' Figs. 6, 14, 15, 16, conlining the description to the mechanism connected with the iiange-turning roll 62, which is similar in all respects to the mechanism connected with the flange-turning roll 61. The roll 62 is carried on a hollow hub 36, that projects from a yoke 72. This hollow hub 36 and the yoke slide on an arbor 64, that is pivotally connected by pivot 65 to the auxiliary frame, whose side beams 71 slide on track 67, supported on bracket 3a. The unpivoted end of the arbor64 engages through yoke 72 on the frame, and the slide-rods 63 and 69 are themselves each made in two parts united by pivots 75, which permit the end of the frame and the arbor 64 to swing when the pivots 65 and 75 are in axial alinement. The end of the arbor 64 is supported in a bearing 76. (See Fig. 16.) The bearing is swiveled in afork 77, the stem of which is provided with a screw 77a and extends through a journaled nut 73 on the auxiliary frame. On the outer end of the nut there is a sprocket-wheel 79, connected by a sprocket-chain to wheels 31, and the wheels 31 are on cross-shafts 5, connecting the two similar frames which carry the two rolls 61 and 62. The slide-bars 63 and 69 are connected by cross-head H, through which runs a screw 32, swiveled to the frame of vise-roll 4 by connections shown at 33. On the screw 32 is asprocket-wheel 34, by which the actuating-screw is connected with and made to act contemporaneously with the corresponding screw in connection with roll 61. An actuating hand-w heel 95, through sprocketwheels 31. engag'es the chains to actuatc the sprocket-wheels 79 and nuts 73 simultaneously. rThe hub 36, with the tlanging-roll journaled thereon, slides on the arbor 64, and the frame-bars engage through guides 37and 33, so that the frame, hub, yoke, and roll move together, while the screw 32 remains practically fixed in position, although revoluble. At the junction between the fork 77 and bearing 76 there is provision made for play of theparts by eng'aging the trunnion-screws of bearing 76 through oval slots 177 in the branches of the fork 77. The loose engagement allows the screw 77l to maintain its position with respect to the frame and allows IOO the arbor 64 to swing as the screw 7 7 a is advanced along its own axis.

The tubular body under treatment is held on the rolls 50, 60, 70, 80, and 90, and these are adjustableto correspond with the size of the tube under treatment. The means of this adjustment will be understood from an examination of Figs. 5, 12, 13, 7, 8, and 9. There are Vseveral diverging rail-guides, one for each steady-roll. Each rail-guide has a flanged track 101, on which engages a grip 102. To the grip is secured a plate 108, in which there is a circular groove 104. The grip-plate is held in its adjusted position on the track by set-screws 105 and 106. The circular groove 104 is undercut, and a circular plate 107 rests on the front of the plate 103 and is held by bolts 108, whose heads engage under the flanges which overhang' the groove 104, and by means of the boltsthe plate is held in any position of rotary adjustment. The plate 107 supports a bracket 111 and above the bracket has a bearingl eccentric to its center, in which is journaled one end of the shaft 110 of roll 109. The outer end of the shaft 110 is journaled in the end of the bracketarm 111. With this construction the bracket can be adjusted around the shaft so as to bring a surfaceof the steady-1011109 to contact the inner surface of the tubular body under treatment and so as to swing' the bracket to a position that the arm part of it will not contact the surface of the tubular body.

The operation of the machine is as follows: The machine is set to the desired width. The rolls 50, 60, 70, 80, and 90 are adjusted to the proper circle for the tubular body which is to be fianged. The inner frame is drawn back to spread the vise-rolls, and the Hanging- rolls 61 and 62 are swung outward until the tubular body D to be treated can be inserted over the roll 3 and its shaft and su pporting-bracket. The inner frame is next forced inward until the tubular body is gripped closely between the rolls 3 and 4. rlhe Hanging-rolls 61 and 62 are swung inward, and the machine is set in motion, causing the tubular body Dto rotate on its own axis. While thus rotating' the i slide- bars 68 and 69 are drawn to force the Hanging- rolls 61 and 62 radially outward from the axis of rotation of the tubular body D or from the aXis of rotation of the roll 8, and the combined rotation of the tubular body and the Hanging rolls, which is brought about by frictional contact with the bending-flange of the tubular body, forces the flange outward until it lies at the desired angle with the body of the tubular body. The inner frame is then drawn backward to spread the rolls 3 and 4, the Hanging-rolls turned outward, the flanged tubular body removed, and another one inserted.

What I claim is- 1. In a Hanging-machine for metallic tubes, the combination of a" rolling vise, means for rotating the vise members and a radiallymovable Hanging-roll movable along a radius of the vise-roll, substantially as described.
