HUGH AUGUSTINE RILEY, OF HOOSIOK FALLS, NE YORK, ASSIGNOR TO DENNIS J. VIIELAN, OF TROY, NEV YORK;

GUTTER-FORMER;

sPEcIFrcAfrroN forming part of Letters Patent No. 614,624, a1-.ed November' 22, 189e. Application iled February 3, 1898. Serial No. @6&9 73. (No model.)

To all whom it may concern.-

Be it known that I, HUGH AUGUSTINE RI- LEY, a citizen of the United States of America, and a resident of Hoosick Falls, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Gutter-Formers, of which the following is a specification.

This invention relates to improvements upon the machine which forms the subjectmatter of the application for United States Letters Patent of Earl G. Vatrous, serially numbered 641,152, iled .lune 17, 1897, for improvement in gutter-formels.

The improvements embraced in the present invention comprise means for transposing the rollers to make different sizes of gutter Without taking the machine in pieces, as required in the former machine, in providing means for firmly holding in position the roller which carries the beading-mandrel during the process of rolling up the bead, in provisions whereby any of ,the rollers or the beadingmandrel may be removed from the machine without disarranging any of its parts, and in an improved supporting roller-brake which is adapted to prevent small rollers from springing away from the companion roller in forming a long piece of gutter.

Theinvention is fully disclosed in the d rawings, wherein- Figure 1 is a plan view of my machine as improved, the central portion of the rollers being broken away. Fig. 2 is an end elevation of the machine. Fig. 3 is an elevation of one end of the front of the machine. Fig. 4 is a perspective view of one of the journal-brackets. Fig. 5 shows the relative position of the parts while the beading-mandrel is passing down between the two formingrollers in the process of rolling up a piece of gutter. Fig. 6 shows how the rollers are forced together after the beading-m andrel has passed out from contact with the presser-roller. Fig. 7 shows the position of the parts after the gutter-plate has passed out from between the formingrollers- Fig. 8 is a side view of my improved roller-brake for holding the rollers together. Fig. 9 is a plan view 0i the sanne. Fig. 10 is a diagrammatical View showing the position of the cooperative parts of the brake during the passage of the beading-mandrel between the bending-roller and the lower roller of the brake. of the position of the parts when the mandrel has reached a point opposite the interval between the two brake-rollers. Fig. 12 shows the position of the parts as the mandrel is passing out from under the upper brakeroller.

The machine will first be described in connection with the drawings, after which the particular features of invention will be pointed out in the claims.

Two journal-stands l l are provided upon which my improvements are mounted, which may be attached to a platform or bench in any convenient way. These are preferably made rights and lefts, and each is provided with an open journal-bearing 2 for receiving and supporting the journals of one of the two rollers of the machine. Whichever of the two rollers is carried in these bearings is called the presser-roller. In this casethis roller is marked 14C. It consists of a piece of metallic pipe Iitted with a head 16 at each end, from which project the journals 17 17, which terminate in squared ends ff for the purpose of taking on a crank 1t), by which it may be rotated when used as a forming-roller. The bearings 2 2 have an inclined opening toward the companion roller and are so made that the outer lip or jaw will overhang the journal to prevent the roller lifting in the working of the machine. The forming-roller is shown at 15 and in all respects, except in size, is like roller 14. Both rollers are itted with a series of tapped screw-holes g g g g for the attachment of a series of mandrel-retaining clips 24E 24, of which two are shown in the drawings. Each of these clips is attached to the roller by a screw or screws e c, dac. These clips are transferable from one roller to the other, as occasion requires. These clips constitute the bearings or supports for the beading-mandrel 25, in which it revolves. This mandrel is a cylindrical rod grooved from end to end, as seen at 26, to receive the edge of the sheet of metal to be formed up, and is fitted at one end with a iianged collar 27, which is rigidly attached to the mandrel, so that. it cannot be slipped Fig. ll is a similar view IOO thereon lengthwise. This flange overhangs the end of the roller to which it is attached, which prevents movement of the mandrel thereon in one direction, while movement in the other direction is prevented by a flanged lip 18, which is secured to the end of the roller. Both ends of the mandrel are squared to take on cranks by which the bead is rolled up, and suliicient space between the surface of the mandrel and the interior of the clips 24 is allowed to provide for the thickness of the sheet metal undergoing manipulation.

The forming-roller operates in open bearings which permit the journals to have a sliding movement toward and away from the presserroller, and which are formed as follows: The upper edge 3 of standards l l is straight, and the journals of the forming-roller rest thereon. The journal-brackets 5 5 have each a shoulder 13, which rests on the edge 3 when the bracket is in place. Each bracket has a forwardlyoverhanging arm ll, which projects out over the edge 3 and constitutes the cap to the bearing in which the journals of the forming-roller l5 revolve. In other terms, these journals ride and turn in the gap thus formed between the edges 3 3 and the under edges of the arms 1l ll, as seen in Fig. 2, which is open on the side toward the presserroller, so that, if necessary, after lifting the presser-roller out of its bearings the formingroller may be slid forward and be similarly lifted out of its position. Thus it will be seen that the rollers are interchangeable both as to their locations in the machine and as to their endwise positions.

The journal-bracket (shown in Fig. 4) has a horizontal recess 6, which shuts over corresponding rib 4E on the stand l when in position. It is confined to the stand by means of a bolt 7, which passes through a hole in the plate S of the bracket and an elongated slot in the stand l, as shown in dotted lines in Fig. 2. Rib 4f, in connection with the groove in the bracket and the bolt 7, afford means for adjusting the bracket toward and from the presser-roller to accommodate it to different sizes of rollers. It has projecting from one side the cam-abutment 9, the back or operative edge of which `consists of the concave b and the ledge lO. The latter parts are designed to cooperate with the edge of the crank-cam 20, which is an integral part of crank lf). This crank-cam is centrally perforated with a square hole to fit the squared ends of the journals of the forming and presser rollers and has a gap 23 cut out of its periphery to allow the socket of the beadingrollei crank to be applied to the ends h h of the mandrel 25, and also to allow the finished length of gutter to be removed or drawn off from the mandrel. One side of the cam-disk 2O is cut away, as on the line from 21 to 22, for the purpose of securing the appropriate means in connection with the cam-abutment 9 for holding the mandrel 25 in a fixed position while it is being turned to roll up a bead,

which function is effected by turning it in the' direction of the arrow, as in Fig. 2, and also for the purpose of allowing the forming-roller to recede from the presser-roller while the mandrel is passing downwardly between the two rollers and after such passage to close up against the presser-roller firmly with the metal plate between them, as in Fig. 6. The performance of these functions will more fully appear in the description of the operation of the machine.

.Any number of rollers within reasonable limits may be employed in this machine, which may be combined or interchangeably used in any desired way. The mandrel-clips may be made so as to take in mandrels of one-half, ive-eighths, or nine-sixteenths of an inch, or, if desired, dilferent clips to closely fit the different-sized mandrels may be employed. This is only a matter of judgment with the operator.

The operation of the machine is as follows: Selection is first made of the particular roller and beading-mandrel upon which it is desired to form the gutter. The mandrel is then laid in position along the surface of the roller and the clips are secured in position over the mandrel. Thus equipped the forming-roller is put in position in its bearings under the caps 1l ll. Another rolleris then selected to serve as a presser-roller, which is likewise dropped into its bearings 2 2 on the stands. The camcranks are then applied to the journals of the forming-roller and the cam-disk 2O turned to the position shown in Fig. 7 or so that its concentric edge will come opposite to and in contact with the concave portion b of the abutment 9. The clamping-bolts 7 '7 being loosened the brackets 5 5 are then crowded toward the presser-roller until the two rollers make contact with the thickness of a piece of the sheet metal to be operated upon between them, although the presence of the metal may not always be necessary. In this position the bolts 7 7 are tightened and the machine is ready for use. In use the first thing is to rotate the cam backward until the shoulder 2l rests on the ledge lO of the abutment. This brings the mandrel or beading-roller 25 into the position seen in Fig. 2, and the same is then turned, so that the groove 26 will open upwardly to receive the edge of the sheetmetal plate. The corner of the plate is then entered in the open end of the slot 26 opposite the collar 27 and is slid into its proper position over the rollers. Vhen so placed, the beading-cranks (not shown) are applied to the ends of the mandrel and are turned t0- ward the shoulder 10 or in the direction of the arrow until a full turn or tliereabout has been made. In doing this it will be seen that the engagement between the shoulder 21 and ledge l0 offers firm resistance to the winding action of the cranks, and thus facilitates a steady and true formation of the bead. The absence of this feature from the machine on which this is an improvement was a serious IOO IIO

defect, as extraneous instead of automatic means of resistance to this winding force had to be supplied. The bead having thus been formed the beadingcranks are removed and the cam-cranks are started, turning in a direction opposite to that of the beadin g-cranks or in the direction shown by the arrows in Figs. 5, 6, and 7. As this turn progresses the clips 24 rst contact with the presser-roller, and further movement tends to crowd the forming-roller backwardly away from the presser-roller until the highest point of the clip is brought down onto the plane of the centers of the rollers, as seen in Fig. 5. To fa- \cilitate this recession of the forming-roller,

and leaves the machine in its original posithe edge of the cam 20 is cutaway', as between 2l and 22; but the instant the clips have passed below dead-center line, so that there is freedom for the forming-roller to move toward the presser-roller, the point 22 of the cam engages the point c of the abutment 9, and further movement of the cranks by virtue of the f ulcrumage thus created throws the forming-roller toward the presser-roller and carries the sheet metal against it. From this point the concentric part of the cam-disk between the points 22 and the gap 23 enters the concave b of the abutment 9 and by means of such curved abutment holds the plate iirmly between the forming and presser rollers during the remaining portion of the revolution of the forming-roller until the plate runs out from between the two rollers, when, being released therefrom, it falls away from the forming-roller, as in Fig. 7, and remains hinged, as it were, to the beading roller or mandrel, from which it maybe detached by rolling the forming-roller to a position to carry the mandrel to the upper side, when the length of completed gutter may be drawn olf from the man* drel through the gap 23, when by a further forward movement of the cam-cranks the clips will be carried over against the presserroller, thus crowding the forming-roller back to the position of Fig. 5. From this last position areversed movement of the cam-cranks throws the shoulder 2l over onto the ledge l0 tion, as in Fig. 2, ready for a new operation.

From experience in the use of machines in which very long rollers of small diameter have been employed it has been found that in the center of the smaller roller it would spring away from its companion roller and not keep the sheet metal in the process of rolling it up against the other roller, and as a result the gutter at this point would be only imperfectly shaped. On account of the obstruction offered by the beading-mandrel in passing between the two rollers, as hereinbefore explained, some device was called for which would not only hold the roller against the plate while the cylindrical part of the rollers were in contact, but would also hold the springing roller to its Work while the mandrel was passing between the rollers, as seen in Fig. 5. For this purpose the apparatus shown in Figs.

S and 9 has been devised. It consists of a stand-bracket 40,which is attached to the machine-bench 60 by means of the bolt and nut 42 43 and the slot 4l, whereby the stand. is rendered transversely adjustable in relation to the rollers. A lever 46 is pivoted to the top of this bracket at 47, between the forks of which a roller 48 is pivoted. From the lower part of the bracket, as at 54, is hung a stirrup 44, which carries the roller-frame 50, pivoted at 49. This roller-frame also carries the two rollers 5l and 52, which are designed to bear against the gu tter-plate or against the surface of the roller upon which the plate is bent. The stirrup 44 has a cross-bar 45 behind the bracket 40, against which the brakelever 46 strikes when the brake-handle is dropped, whereby the stirrup is thrown back, so as to withdraw the rollers 5l and 52 from contact with the roller 15 and hold them back out of the way. When the handle is dropped, the parts take the positions indicated by the dotted lines in Fig. 8. In use the brake-roller 48is designed to bear against both the stirrup-rollers 5l and 52, and by lifting the handle the stirrup-rollers will be thrown against whatever may be carried against them in process of revolving the roller l5. I By raising or lowering the hand the brake-roller will follow the oscillating movements of the rollers in the frame 50 and by doing so will force both the stirrupe-rollers against the roller 15 or one against the mandrel and the other against roller l5 or both against the mandrel, asin Fig. ll, and the mandrel against the roller 15; but in every case the pressure applied to the brake-roller will be transferred to the roller 15, and thereby it will be prevented from springing outwardly or away from its companion roller 14. By this yielding combination of levers, roller-frames, and rollers it is entirely feasible to revolve the beadingmandrel under the brake-roller Without its pressure being at any point withdrawn from the gutter-plate or the forming-roller, according to whichever of the two may be in contact with the stirrup-rollers.

Having thus described my machine, what I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination in a gutter-former with a presser-roller carried in fixed bearings and a forming-roller carrying a bead-forming mandrel; of elongated bearings for the formingroller in which its journals can both turn and slide toward and away from the presser-roller and means for forcing and holding the forming-roller to its duty in connection with the presser-roller in the bending of a plate.

2. In a guttenformer the combination with a presser-roller carried in fixed bearings open at one side to permit removal of the roller therefrom, and a forming-roller carrying a bead-forming mandrel, of elongated bearings for the forming-roller in which its journals can both turn and slide toward and away from ICO IIO

the presser-roller and means for forcing and holding the forming-roller to its duty in connection with the presser-roller in bending a plate to form a gutter.

3. In a gutter-former the combination with a presser-roller carried in fixed bearings and a forming-roller carrying a bead-forming m andrel, of elongated bearings for the formingroller open toward the presser-roller to permit ready removal of the forming-roller therefrom and in which its journals can both turn and slide toward and away from the presserroller, and means for forcing and holding the forming-roller to its duty in connection with the presser-roller in the bending of a plate to form a gutter.

et. The combination with the beading-mandrel mounted on the forming-roller, of the forming-roller and means connected therewith for preventing its rotation and resisting the tendency of the mandrel-cranks to turn in the same direction as the mandrel turns in the process of rolling up a bead.

5. The combination with the stands and journal-brackets having the elongated journal-bearings, of the forming-roller carrying the beading-mandrel, the crank-cam having the shoulder and the ledge on the bracket which cooperates therewith.

G. The combination ot a stand which forms the lower member of an elongated open journal-bearing, with an adjustable bracket having an arm which overhan gs said lower member and forms the upper member of said bearing.

7. In a gutter-former, the combination with two cooperative bending-rollers, of a pair of detachable cranks adapted to fit either roller, and bearings in which said rollers rest in operation, all of which bearings open in a direction opposed to the line of thrust in bending a plate, as a means of promoting interchange or transposition of the rollers.

S. The combination with a forming-roller of a pair of bearing-rollers carried in an oscillatory frame which is hung in a swingin stirrup pivoted to a stand upon which is pivot-ed a brake-lever which carries a roller that is adapted by the movement of the brake-lever to be brought to bear against one or both of eigene the bearing-rollers to crowd them against the forming-roller, or against any material. carried by 0r being formed thereon.
