This invention relates to a metal working machine, more particularly for seaming strips or sections of sheet metal together, such as fenders and skirts for automobiles.

One object of the invention is to provide a machine of this character of relatively simple construction, comprising few parts which may be readily operated.

Another object of the invention is to provide a machine of this character with an, attachment capable of holding and guiding the strips or sections of metal to the seaming elements, whereby they may be seamed rapidly and easily, as well as accurately.

Other objects of the invention will be apparent to thoseskilled in the art to which my invention relates, from the following scription, taken in connection with the accompanying drawings, wherein,

Fig. 8 is a detailed view of the power reversing mechanism for the driving shaft.

Fig. 9 illustrates a machine embodying my invention but of slightly modified construction..

In the drawings, 1 indicates a frame which ,may be of any desiredconstruction, being preferably hollow to reduce its cost and weight, while providing a support for the drivensha-fts 2, 3, to be later referred to. The frame 1 is fashioned to provide upper and lower arms 2 3", which support the metal working elements, that is, the seaming elements 4: and 5,respectively, at

their outerends, and provide ample space to permit free movement of the metal strips between the arms, as they pass the seaming elements at, 5. The upper surface of the arm 3, near its outer end, is formed with an opening 6, which is flanged at 6 ,to form a seat for a tubular member 7. member 7 is flanged atjits lower end, and such flange rests on and is secured to the flange 6, preferably by cap screws 8. 3 indicates a standard guided to move vertically in the tubular member 7. The upper end of the standard 9 is provided with anopening 10 (see Fig. 6) to receive a stud shaft 11. The stud shaft 11 is secured in positionin the opening 10 by means of a nut'll, engaging it at one end. The opposite end of the stud shaft 11 serves as a support for a sprocket 12, having a hub 13, to which is keyed, in a well-known manner, the seaming element 4. I

At its lower end, the standard 9 carries alug 14, towhich is pivotally connected a collar 15,-form'ing a bearing for the front endof the shaft 2. The shaft 2 extends through the bearing 15, and carries at its'outer end a sprocket 16, in linewith the sprocket 12, whereby the latter may be driven by the formerjby a chain 17. shaft 2 is supported by a bearing 18, pivot-- ally supported by a cross rod 19, supported at its opposite ends in the walls of the frame 1. By pivotally supporting the shaft 2 at its rear end in the frame 1, and supporting its outer end on the standard 9, it will be seen that the latter may be moved or ad justed vertically while maintaining driving connection with the sprocket 12, to which the seaming element at is connected. By preference, the wall of the standard 9 is shaped to form a guard 9 for the sprocket 12, as

most clearly shown in Figs. 6 and 7.

20 indicates as an entirety adjusting means for the standard 9, whereby the seam-' ing elements may be caused to cooperate with the seaming element 5, to scam the strips of metal according to the gauge of the metal being operated 7 upon. Of these means, 21 indicates a plate fixed to the front end of the arm 3*, preferably by means of cap screws 22. The plate '21 isformed with Fries". f

The rear end of the The tubular an opening 23, and provided with tubular bosses 23, 23 which form a bearing for a shaft 24. The shaft 24 carries a hand wheel 25 at its outer end. At its inner end the shaft 24 is provided with a cam 26 which engages the lower end of the standard 9, as shown in Fig. 2, preferably in line with its axis. If the hand wheel 25 is rotated in one direction, the cam 26 will cause the standard 9 to move upwardly; if it is moved in the opposite direction, it will allow the standard to move downwardly.

27, 28, indicate a pair of spaced members, formed with pairs of aligned openings; one pair of such openings serves to receive and support the front end of the shaft 3, and the other pair serves to receive and support a shaft 29. The member 28 is preferably supported at its upper end by the shaft 3, while its lower end is held stationary between a pair of bolts 30, only one of which is shown in Figs. 1 and 6. The members 27 and 28 are spaced relative to each other, to provide room for gears 31, 32, keyed in a well known manner to the shafts 3, 29, respectively, and meshing with each other, whereby the power of the shaft 3 is transmitted to theshaft 29. The outer end of the shaft 29 is preferably reduced to receive the hub of the seaming element 5, this hub being keyed to the shaft and held thereon by a nut 33. The shaft supporting member 27 is preferably held in position by a plate 34, secured to the front end of the arm 2 by a cap screws The shaft 3 is providedwith a sprocket 36, over which a chain 3'? runs, said chain engaging a sprocket 37 on the shaft 2, and thus transmitting the power thereof to the shaft 2. As shown in Fig. 1, the frame 1 is provided in its rear wall with an opening surrounded by bosses l, which serve as a bearing for the extended inner end of the shaft 3. 38 indicates a gear fixed to the free end of the shaft 3, beyond the frame 1. The gear 38 meshes with a gear 39, which in turn meshes with a gear 40. The gear 40 meshes with a gear 40, which is fixed to a main driving shaft 41; the shaft 41 is preferably driven by a belt pulley 42, being connected to the shaft 41 and disconnected therefrom by a suitable clutch 43, operated through connections 44 by a foot pedal 45. The gears 39 and 40 are mounted in a frame 46, which straddles the gear 40 and loosely pivots on the shaft 41, whereby it may swing to the position shown in dotted lines in Fig. 8 to cause the gear 40 to engage the gear 38 and the gear 39 to disengage the latter. Vhen thus operated, the rotation of the shaft 3 will be reversed. The frame 46 may be operated by a link 4'? connected to a hand lever 48. The mechanism for reversing the direction of rotation of the gear 38 is desirable so that the machine may be equipped with my improved holding and guiding attachment, indicated as an entirety at 49, at either side of the frame 1, whereby sheets or strips of metal to be seamed together may be fed to the seam ing elements in either direction, it being obvious that in some instances thesheets or sections of metal must be guided to the seaming elements in one direction and in other instances in the other direction. The seaming elements 4, 5, preferably comprise a flat roller and a channeled roller, respectively, which co-operate, as shown in Fig. 6, to roll down the interlocking flanged portions a of the metal strips, such a fender A and a skirt B, into a seam.

(lit the holding and guiding attachment 49, 50, 51, indicate a pair of grooved rollers adapted simultaneously to engage the sheets of metal along their folded edges, and through their co-action, one with the other, to hold the interlocked flanged portions a of the sheets in assembled relationship (see Fig. 5) while guiding such portions to the seaming elements 4, 5. The rollers 50, 51, are mounted to move relatively to each other, that is, outwardly, to permit the positioning of the sheets of metal between them (see F 1.) and then toward each other into operative position, as shown in Fig. 5, to maintain the flanges a in interlocked relation or position for seaming. As will be understood from Figs. 1 and 5, the rollers 50, 51, (i) when in their separated position, are disposed at opposite sides of the plane in which the seaming elements are disposed, but move in a direction transverse to that plane toward each other to engage the folded edges of the sheets and (2). are arranged simultaneously to engage the folded edges of the metal sheets at a position which is or which maintains the interlocked flanges in alignment with the seaming elements 4, 5. By maintaining the rollers in engagement with the folded edges of the metal sheets, they will serve to hold the latter in assembled relationship as well as to properly guide them to the seaming elements. 52 indicates a lever pivotally mounted upon a bracket 53, and carrying at its lower end the roller 50. 54 indicates a lever pivotally mounted upon a boss 55 projecting laterally from the standard 9 and carrying at its upper end the roller 51. As shown, the levers are mounted on axes which extend in direction transverse to the direction of movement of the sheets or strips through and between the elements 4, 5, so that the holding and guiding rollers 50 and 51 move toward each other at substantially right angles to the direction of movement of the metal strips or interlocking portionsthereof. The levers '52, 54, are connected to suitable devices, indicated as an entirety at 56, whereby they may be moved simultaneously. The devices 56 pref erably comprise a lever 57, fulcrumed intermediate its ends at 58, the upper end of the lever being connected by rod 59 to the upper end of the lever 52, and the lower end of the lever 57 being connected by a rod 60 to the lower end of the lever 54. As will be understood from Figs. 1 and 2, theconnection 61 between the lever 57, and the rods 59, 60, respectively, and between the latter and the levers 52, 54, respectively, are pivotal' ones, to permit of relative movements between these elements. Preferably each connection 61. comprises a block 62, which is formed'with an opening to receive the adjacent rod. As shown, the rod is threaded to receive nuts 62, which are tightened against the block, and thus secure the rod and block together. ment also permits each rod to be adjusted, relative to the levers 57 and 52 or 5a, to insure proper co-action between the holding and guiding rollers 50, 51. At one side the block is provided with a pin, 63, which loosely fits an opening 64, in the adjacent lever. The outer end of the pin 63 is thread ed to take a nut, 65, to prevent disengage ment of the lever and rod.

66 indicates as an entirety means for op erating the devices 56. The operating means 66 may comprise a bell crank 67, having a pivotal connection with one of the elements of the operating devices 56, such as the rod 60, a link 68 connected at one end to'the bell crank 67, and at its other end to a foot pedal 69. The bell crank 67 is. pivotally connected to a collar 7 O, which in turn is adjustably' connected to the rod.

60, preferably by a set screw 71.

Each of the rollers 50, 51, is preferably mounted for adjustment, namely, in a direction that is substantially transverse to the plane in which the other roller is mounted, and angularly about the end of the adjacent lever, whereby their relative relationship when in operative position may be changed to insure their positive operation, according to the size or width of the folded portions of the sheet metal and the interlocking relationship of the sections to be seamed. As the mounting for each roller 50, 51, is similar to that for the other roller, a description of the mounting for one of them will be suflicient. For example, the roller 50 is loosely mounted in a bushing 72, which is supported on the free end of a stud shaft 73 by a screw 74, fitting an opening in the. end of the shaft. The shaft 7 3 slidably fits an opening 75 formed in a'block 76, being fixed therein by a set screw 77. The block 76 is rigidly connected to a bar 78, which rotatably fits an opening 79 formed in the free end of the lever 52. The pin or bar 7 8 extends through the opening 79, and is screw threaded at its outer end to take a nut 80, whereby it may be secured in its adjusted position. This construction is advantageous since it permits the rollers 50,

This arrange- 51, to be transposed so that the roller 50is at the outer sideof the rolling down or seam ing elements 4:, 5, and the roller 51 is at the inner side thereof-see Fig. 7 ,such arrange ment being desirable when the seaming operation is to be effected upon a pair of metal 1 strips or sheetstransposed from that shown in Fig. 5. Y

As will be understood from the drawings, the lever 5% is mounted on the standard 9, and movestherewith whenever the standard is adjusted, this arrangement serving to maintain the holding and guiding roller 51 in alignment with the adjacent seaming-element 4- at all times.

The attachment 49 may be arrangedupon either side of the frame I or the attachment may be duplicated upon opposite sides thereof. In this latter construction certain elements thereof may be removed,dependent upon the direction in which the metal sheets.

are fed to or through the sean'iing'elements.

For this purpose, the standard9 is provided with a boss 55, at either side thereof, and the f frame 1 is formed on its opposite sides with openings for the fulcrums 58 for the levers 5 In Fig. 9 I have shown a slightly modified form of metal working machine in which the operating elements may be shaped to seam or head the interlocking sections of the metal. Referring to this figure, 1 indicates the frame having spaced projecting arms 81, 82, carrying at their outer ends a pair of metalworking elements 88, 84, respectively. '85, 86, indicate a pair of holding and guiding rollers loosely mounted on levers 87, 88,respectively, hereby they may be movedtoward or from each other. The levers, 87, 88 are pivotally mounted on brackets 89, 90, carried by the arms 81, 82, respectively. The levers 87, 88, are connected by rods 91, 92, respectively, to the free ends of a lever 98 pivotally mounted on the frame 1*. The lever 93 is connected by a rod 94 to a foot lever 95, whereby the guiding rollers 85, 86, are moved simultaneously toward each other or in the oppositedirection.
