This invention relates to a combined shearing and bending machine for lath metal.

It is an object of the present invention to provide a combined shearing and bending machine by which straps of large sheet material can be cut and while upon the same pass of the large sheet material the cut straps will be bent into angle section.

Other objects of the present invention are to provide a combined shearing and bending machine which can be fabricated from stock pieces of material, which will be compact, easy to construct and assemble, and efficient in operation.

For a better understanding of the invention reference may be had to the following detailed description taken in connection 'with the accompanying drawing, in which Fig. 1 is a top plan view of my shearing and bending machine,

Fig. 2 is a front elevation view of the machine looking upon the cutting and crimping rolls,

Fig. 3 is a rear elevational view looking upon the drive connections to the roll shafts,

Fig. 4 is an end elevational view of the machine looking at the end of the same which has the crimping or bending rolls,

Fig. 5 is a transverse cross-sectional view taken on line 5-5 of Fig. 2 and looking in the direction of the arrows thereof,

Fig, 6 is a cross-sectional view, in elevation, taken on line @-5 of Fig. 2 and looking in the direction of the arrows thereof and through the crimping or bending rolls,

Fig. 7 is a fragmentary cross-sectional View taken upon one of the threaded posts and as viewed on line 'I-l of Fig. 1 and looking in the direction of the arrows thereof,

Fig. 8 is a cross-sectional View, in elevation, taken on line 8-8 of Fig. 1 and looking in the direction of the arrows thereof and through the cutting roll shaft housings,

Fig. 9 is a cross-sectional view taken through one of the bearings and the top crimping roll shaft and as viewed on line 9-9 of Fig. 1,

Fig. 10 is a fragmentary and detailed crosssectional view taken through the guide plate on the table and as viewed on line I-I of Fig. 1 and looking in the direction of the arrows thereof.

Referring now to the Jrigures, I5 represents a base plate from which there is extended upwardly to the cutting roll side of the same four posts I6 which are threaded into the base as shown at I'l, Fig. 8. Upon these posts I5 there is mounted a spacing block I8, a plate I9, a lower cutting shaft housing 2|,

plates

22 and 23, upper cutting roll housing 24 and a top plate 25. All of these parts are secured tightly to the base by a clamping washer 25 and a nut 2l on each of the posts I5.

Extending through the housing 2I is a lower cutting roll shaft 2S mounted in ball bearing elements 29 at opposite ends of the housing 2I and having extensions 3I and 32 extending from the opposite ends of the same. On the extensions 3| is a feed roll 33 vhaving a rubber ring portion 34. Also on the extension 3l is a lower cutting roll 35. These rolls are secured upon the extension by a clamping nut 36. On the other extension 32 is a gear 3l, a sprocket 38 and a drive coupling element 39. These parts are retained upon the ex.. tension by a nut 4 I.

In the upper housing 24 is upper cutting roll shaft 42 journalled in ball bearing elements 43 in opposite ends of the housing, Fig. 5. This shaft has at opposite ends of the same extensions 44 and 45. On the extension 44 is a feed roll 45 having its rubber ring portion 41 engaging with the rubber ring portion 34 of the feed roll 33. Also upon the extension 44 is upper cutting roll 48 cooperating with the lower cutting roll 35 to effect a shearing action of any sheet material extended between these cutting rolls. A nut 45 retains the upper feed roll and the cutting roll 48 upon the extension 44.

On the extension 45 is a driving gear 5I meshing with the gear 3l of the lower cutter shaft 23 so as to be driven thereby and to cause the rotation of the cutting roll 43. There is also on the extension a sprocket 52 and the gear 5I and the sprocket 52 are retained upon extension against axial displacement by a clamping nut 53. A key 54 fixes the gear 5I and the sprocket 52 to the extension 45 against rotational displacement. A similar key 55 is provided on extension 44 for the feed roller 46 and the cutter 48. Likewise the part on the extensions of shaft 28 are keyed thereto.

Plate 23 serves as a table on which the sheet material is extended when passing the same through the

cutting rolls

35 and 48. This plate 23 is supported externally of the housings 2| and 24 by a, vertically extending plate 55 which may be welded to the same and to the base I5. In the plate 23 are elongated slots 5l through which bolts 58 may extend for clamping the angle guide 6I in any of its adjusted positions. The sheet material is rested upon the table top or plate 23 and slid toward the

cutting rolls

35 and 48 and upon being engaged by the feed rolls 33 and 46 will be drawn into the machine. Metal laths will be cut anywhere from a small fraction of an inch 3. to six inches depending on the lateral adjustment of the guide or gauge 6|.

The severed metal lath will automatically pass to top and bottom crimping or bending rolls 62 and G3. The top roll 62 is keyed as indicated at S4 to a shaft 65 journalled in

bearing brackets

66 and 67, Fig. 6, secured by bolts 68 to top plate 25. On the opposite end of the shaft 65 there is fixed a sprocket 69 which is connected by a chain H to sprocket 52 of the cutter roll shaft 42 so that the crimping roll shaft 65 will be driven by the same.

To the plate I9 there is connected bearing brackets 72 and 13 through which extends a lower crimping roll shaft 'M having the crimping roll 63 thereon. A key 75 fixes the roll 63 upon the shaft 'ld against rotation relative thereto. On the opposite end of the shaft there is fixed a sprocket 77 which is connected by a lower chain 18 to sprocket 38 of the lower cutting roll shaft 28. It will thus be seen that power is delivered to the crimping or bending

rolls

62 and 63 by means of chains 'H and 78.

Plate 22 extends laterally from the cutting roll housings 2l and 24 to support the severed lath upon being passed through the crimping or bending

rolls

62 and 63. The plates E9, 22 and 25 are all supported on the output end of the machine by threaded posts 8l and 62. These posts have threads extending throughout their entire heights and the plates can be adjusted along them by turning upper and lower retaining

nuts

83 and 84. Spring washers 65 may be disposed between the nuts 33 and 64.

Within the plates I9 and 25 which support the lower and upper bearing rolls there are provided at their connection with the post i6 elongated slots 86. This will permit the plates to be laterally adjusted so as to release the chains 7l and 78 or permit the connection of the chains with the sprockets. The bearing brackets for the crimping roll shafts may be connected at different distances from the mounting plates by replacing shim plates 87 disposed between the brackets and the plates. By using shims of different thicknesses diiTerent size and

shape crimping rolls

62 and 63 can be used.

While various changes may be made in the detailed construction it shall be understood that such changes shall be within the spirit and scope of the present invention as dei-ined by the appended claim.

I claim:
