Patented ma a, rare.

Application filed August 12, 1915. Serial No. 45,205.

To all whom it may concern:

Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States, and a resident of Hillsdale, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements 1n Machines for Making Shingle-Strips, of which the following is a specification. I

This invention has for its object to provide a machine which may be used in the manufacture of shingle strips which may be used for covering roofs, side walls and the like.

. As set forth -in Letters Patent No. 1,150,298, granted to me on the 17th day of August, 1915, shingle strips are formed of what is known as prepared roofing mate'- rial; that is to say, a sheet or foundation of felt or equivalent fibrous material saturated or impregnated with a relatively low-melt- "ing-point pitch, asphalt or other hydrocarbon and coated on one or both faces with pitch or asphalt, themelting point of wh ch is high enough to prevent injurious actlon thereon by solar heat. This pitch or asphaltv shingle strips, and for forming on that portion of the strip, which is to be exposed when laid in overlappingrelation to others, tabs or projections of predetermined shape or configuration, which, when the shingle strips are laid, simulate tiles or shingles.

Qn the accompanying drawings,Figure 1 represents in plan view a machine embodying the invention. Fig. 2 represents a longitudinal section through the same on the line 2-2 of Fig. 1. Fig. 3 represents one of the cutters. Fig. 4 illustrates a shingle The invention contemplatesthe combina I tion ofmechanism for feeding the elongated sheet longitudinally, cutters for forming longitudinal slots arranged in rows across the sheet, and means for severing the sheet in a line intersecting the slots of eachtrans- -verse row. It will be quite evident that these several elements or instrumentalities may take different forms and be arranged in different ways without departing from the spirit and scope of the invention.

In the embodiment of the machine as shown, the cutters for. forming the rows of slots are so arranged and formed as to cut into the sheet pairs of longitudinal slits of the same length connected at their rear ends by cross slits so as to leave tongues attached at one end of the body of the sheet. Preferably the draw rolls or feeding rolls are from the shingle strip which is completedby the severing cut. The severed shingle strips, as they are cut successively from the sheet, are received by open carriers which feed them away from the machine and permit the detached tongues to pass therethi-ough and not become commingled with the finished product. Preferably the feeding of the sheet is continuous, the parts being so timed that the sheet is fed a. predetermined distance before it is severed transversely into sections by the chopping knife.

Referring to the drawings, the machine there shown is provided with a frame-Work of any suitable character, and may comprise ings are well known, I have not shown them in detail. Power is transmitted to these feed rolls by a train of gears which I shall subsequently explain.

The sheet of roofing A is drawn either from a roll or it may be drawn directly from the machines in which it is saturated, coated and surfaced with crushed mineral. As it enters the machine embodying the present invention, it passes between coacting'cutters which are indicated as a whole at 14: and 15. The cutters 1a are adjustably secured upon a shaft 16, whereas the cutters 15 are adjustably secured upon. a shaft 17, both shafts being journaled in suitable bean ings in the framework. Each cutter 15 consists of a disk of the desired width, having on its periphery thetwo shear blocks 18 and 19. The side edges of the block 18 are in shearing relation with the slittingblades forming a part of the cutter 1 1, whereas the end edge 18 of the block 18, and the block 19 cooperate with a cross blade forming a.

part of the same cutter 1 1. These shear blocks 18 and 19 are secured upon the cut ter 15 by any suitable fastenings. Each cutter 15 comprises a hub 20 formed at the end with a peripheral flange 21. To each face of the flange are secured two segmental slitting blades 22 which are adapted to coiiperate with the shear blocks 18 of the coacting cutter 15. The flange 21 is provided with sockets 23 to receive the cross-cutting blades 24;, the chisel edges of which cooperate with the end edges 18* of the shear blocks 18. The blades 24 are secured in their sockets by screws or other fastenings 25, the flange 21 being recessed to receive the same as shown in Fig. 6. Each cutter, as thus described, is

provided with two sets of knives or two sets of shear blocks as the case may be, so that, during one complete revolution of the coacting cutters, two sets of slits will be formed in the sheet. The blades 22 and their cooperating shear block 18 will cause the formation of parallel slits b b as shown in Fig. 7, the rear ends of these slits to be connected by a cross slit 0 formed by the blade 24- and its cooperating shear block 18. This causes the formation of tongues al which are forced upwardly by the shear blocks from the plane of the sheet and which are attached at their front ends 0 to the body of the sheets As the sheet passes hatween the rollers, the tongues cl are received by the grooves 13 of the feed roll 12 and are not forced back into the plane of the sheet so as to stick or adhere to the walls of the slot. The material, which is employed for impregnating the sheet, is more or less sticky and adhesive, and, when the tongues are forced back into the sheet, they stick in the slots and are difiicult to remove; whereas, by forcingthem out of the slots, they do not adhere when the sheet is subsequently transversely severed. After leaving the feed rolls, the sheet A passes over a shear block or bed 26 with which cooperates a chopping blade 27 secured on a rotatable cutter 28. The latter is relatively heavy and solid so as to insure a severing out which will be clean and not ra ged. This cutter 28 is secured upon ashaft 29 journaled in hearings in the frame-work. The parts are so timed that the cutter 28 severe the sheet on a line f (see Fig. 7) which intersects the ends of the slits b so as to cause the severance of the tongues cl at their attached ends. As a result, each severed portion of the sheet constitutes a shingle strip, such as shown in Fig. 4: at g and having a plurality of tabs or projections h separated by recesses '5. These tabs or projections can be formed of difierent widths, according to the adjustment of the cutters 1d and 15 on their respectiveshafts l6 and 17, and I employ interchangeable feed rolls 12 having grooves corresponding to the width of the recesses so as to receive the tongues as previously explained.

Below the shear block there is an inclined plate 30 On which the severed portions of the sheet or the shingle strips slide until they are received by the open endless carriers 31. These carriers consist of chains or other suitable endless belts mounted upon sprockets 32, 33, or equivalent devices. The sprockets 32 are'upon a shaft 34 journaled in the frame-work, whereas the sprockets 33 are on a shaft 35 journaled in bearings upon the ends of brackets 36 secured to the framework. As the finished shingle strips are being carried away in the direction of the arrow in Fig. 2, the severed tongues drop between the several carriers and accumulate in a pile without becoming mixed or intermingled with the finished shingle strips.

It is quite evidentthat the draw or feed rolls, the slitting cutters and the chopping mechanism may be all operated in proper 12o timed relation by any suitable power-transmitting mechanism. As illustrating conventionally a suitable means for accomplishing this purpose, I have shown the machine as being provided with a driving pulley 37 on the shaft 3A. This last-mentioned shaft has a gear 38 intermeshing with and driving a large gear 39 on the shaft 29. On the other end of the shaft there is a pinion 40 engaging a gear 41 journaled on the stud 60 comprising means for longitudinallyfeedmeans shaft and intermeshing with an idler gear 12 likewise mounted on the stud shaft and all on the front side of the machine. last-mentioned idler gear 42 intermeshes with and drives a gear 43 secured on theend of the lower feed roll 11. On the rear end of .the last-mentioned roll and on the like end of the roll 12 are 'intermeshing gears 44, 45, to cause the two feed rolls to be driven in unison. From the-gear 44; power is transmitted to a gear 46 on the knife shaft 17 by an intermediate idler ear 47. The gear 46 intermeshes with the gear 48 formed on the knife shaft 16. In lieu of the train of gearing which I have just described, any other suitable power-transmitting mechanism may be utilized.

A sheet of roofing having been prepared as herein described, on being fed through the machine, has formed therein the longitudinal pairs of slits, the slits of each pair being connected by the cross slits and thus forming attached tongues. Thereafter the The sheet is severed to provide a series of shingle strips.

The invention, as herein described, and embodied in a suitable machine, is capable of producing shingle strips in large quantities and at very small cost. The sheet, during its travel-through the machine, may be guided by any suitable guides, but I have not shown them as they constitute an obvious mechanical expedient.

It is evident that the longitudinal slits 'of-each pair of slits need not necessarily be straight or parallel, and that cutters of other forms may besubstituted therefor to produce tabs or projections of different shapes and in simulation of ornamental tiles or shingles. So far as any common generic inventions or improvements as herein claimed are concerned, this is a continuation in part of my previous application Serial No. 23,153, filed April 22, 1915.

Having thus explained the nature of my said invention and described a way of making and using the same, althoughwithout attempting to set forth all of the forms in which it may be made or all of the modes of its 'use, what I claim is: 1. A machine for making shingle strips, comprising coacting feed rolls for longitudinally feeding an elongated sheet of roofing felt, cutters on one side of saidfeed rolls for forming transverse rows of longitudinal tongues in said sheet, and a chop ping cutter on the other side of the feed rolls for transversely severing said sheet on a line intersecting the 'bases of saidtongues. 2. A machine for making shingle strips,

ing an elongated sheet of roofing felt, cutters for forming a series of transverse rows of longitudinal tongues therein, and means for simultaneously severing the end of the sheet and the ends of the tongues on a trans dinal slits of each pair, and means for severing the end of the sheet on the transverse line intersecting the forward ends of said longitudinal slits, whereby, said sheet is formed into' shingle strips each having a plurality of shingle-like tile-like tabs or projections along one edge.

4. A machine for making shingle strips, comprising coacting cutters having longitudinal and transverse slitting blades and complemental shear blocks, for forming slots in the sheet and corresponding raised tongues attached at their front ends to the body of the sheet, feed rolls formed to feed the sheet without returning said tongues to the plane of the sheet, and a chopping cutter for severing said sheet on a line intersecting the bases of the tongues.
