SHINGLE STRIP MACHINE Filed Nov. s; 1926 s Sheets-Sheet 5 {NEW 1 11 W- immmi Patented May 13, 1930 UNITED STATES PATENT OFFICE vHUGO REICHEL, OF CHICAGO, ILLINOIS SHINGLE-STRIP MACHINE Application filed November s, 1926. Serial No. 146,961.

Itis found in practice that in cutting a web of the material into strips, some of the strips are not entirely severed and it is another object of the invention to provide novel, economical and effective means for accomplishing the complete severance of such strips as have not been entirely severed in the cutting operation.

Other further and more specific obj ects will become apparent from consideration of the specification. and drawings wherein:

showing the cutting lines resulting from feeding the material strip between a pressure roller and the cutter head; and

Fig. 13 is a view along the line 1313 showing a typical section of a bearing box.

Referring to the drawings, the machine comprises a supporting framell, upon which are mounted the feed rollers, pressure rollers. cutter heads and driving gears. A pair of standards 12 positioned at a convenient disheads 23 and 25 andthe feed roller 28 are adtance from the frame 11, provides a support 9 for a series of rollers operating for a purpose to be hereinafter more fully explained. Upon the front of the frame 11, is mounted a pair of standards 13, which furnishes a mounting for a pair of feed rollers 14 and 15 between which a fabric sheet 16 is to be fed.

The rollers 14 and 15 are adjustable relative to each other by threading the nuts 17 and 18 on and off the bolts 19. The bolt 19 is mounted at its lower end in a box 20 which is slid able between the arms 40 forming the upper portion of the standards 13. The arms 40 form a guideway in which the box 20 moves when the nuts 17 and 18 are turned on and of? the bolts 19. The construction of the guide way is best shown in Fig. 13.

Pairs of standards 21 and 22 are shown at the top of the supporting frame 1.1 to pro-. videgsupports and guideways for a cutter head 23 overlying a roller 24 and a cutter head 25 overlying a roller 26 respectively. A pair ofstandards 27 is likewise. provided as supports for feed rollers 28 29. The cutter justably mounted in their respective pairs of standards by nuts 17 18 bolts 19 and boxes 20 similar to the mounting provided for the feed roller 14. Y

The rollers and cutter heads are actuated by a series of gears and a chain drive from a motor not shown), so as to move the fabric to the rightas shown in Fig. 1. The power is applied to the gear 30 so as to' rotate it in an anti-clockwise direction. The gear30 meshes with a relatively large gear 31 which is fixedly mounted on the roller 24 to actuate the same in a clockwise direction. A sprocket 32 mounted on the roller 24 and a chain drive 33 fastened on the roller 26. The gear 37 meshes with an idler 38 which in turn meshes with a gear 39.-the latter being fastened on the roller 29. Each of the rollers 15, 24, 26 and 29 are thus-rotated in a clockwise direction. A

gear 51 on the roller 15 meshes with a gear 9 an anti-clockwise direction as viewed in The cutter head 25 is shown as of smaller diameter than is the cutter head 23. Only one of the cutter heads is maintained 1n operative position at any one time, use being made of the nuts 17 and 1S and the bolt 19 for the purpose of moving the cutter heads into or out of their operative position. It is thus possible to cut the web of material into strips of differentsizes as desired by merely throwing the cutter heads in or out of gear as shown or by substituting heads of smaller or larger diameter than those shown in the machine.

In Figs. 10 and 12, are shown a typical cutter head 23 and a portion of a web of fabric 16 respectively, after the web has been run between the cutter head and its cooperating roller. The web is shown as cut into SIX longitudinal strips and each of the strips as cut transversely at regular intervals to form relatively short strips 45. The width of the strips as well as their length depend upon the size of the roller used while their indentations and lateral projections depend upon the arrangement of the knives upon the cutter head.

One of the chief features of novelty in the invention lies in the provision of an angular cross-sectioned cutter head which can be easily and economically manufactured by casting andupon which the knives 46 are mounted and fastened to the cutter head by means of bolts 47 and ordinary angle irons 48. The knives and angles include the knives 46 and angle irons 48 extending longitudinally of the cutter head, the diagonally extending knives 46 andangle irons 48", and the knives 46 and the angle irons 48. The knives 46 are riveted to the angle irons 48 and for the purpose of easy removal of the knives the angle irons are fastened to one of the faces ofthe cutterhead by means of bolts 47.. The knives-are of such depth and shape as to have thei cutting edges lying in a cylindrical surface concentric with the axis of the cutter head'as best shown inFig. 6. In operation the cutter head and its cooperating roller are so positioned that the surface of the roller is tangential to the cylindrical concentric surface in which the cutting edges of the knives lie. The knives 46, 46 and 46 are positioned so that they form continuous cutting edges with the result that the fabric is cut as indi catcd in Fig. 12. By providing a plurality of bolt holes for the bolts 47 the direction o the knives can be varied at will and resulting projections and indentations likewise varied. The cutter head is shown as hexagonal in cross section but it can be made octagonal or of any other desired angular cross section, which feature by reason of its economy of manufacture and ease of assembly and mounting constitutes one of the highly desirable objects of the invention.

The rollers 14 and 15 comprise shafts 53 and 54 upon which a plurality of concave and convex rollers 55 and 56 are respectively mounted. The sheet 16 is fed between these rollers after being cut into longitudinal strips 45 for the purpose of completely severing the lateral edges of the strips. This object is accomplished by reason of the strips being temporarily corrugated longitudinally between the concave and convex rollers as best shown in Fig. 2. Such corrugation of the strips necessarily diminishes their ovcr-all width and requires the separation of the lateral edges of adjacent strips.

Thus it will be seen that I have provided .an economical and novel cutter head and knife mounting and novel means for separating the sections of shingle strips.

I claim 1. In a shingle strip machine, the combination with means for severing a sheet of material into a plurality of generally longitudinal strips, of means for separating the contiguous edges of adjacent strips, said separating means comprising corrugating rolls through which said strips are fed to corrugate the strips longitudinally. I

2. In a shingle strip machine, the combination with means for severing a sheet of material into a plurality of generally longitudinal strips, of means for breaking any final adhesion of the adjacent edges of such strips said breaking means comprising a plurality of pairs of concavo-convex rollers between which the individual longitudinal strips are fed.

In testimony whereof I have affixed my signature,

HUGO REICHEL.
