SHINGLE-STRIP-MAKING MACHINE.

Patented Feb. 26, 1918.

- To all whom. it may concern:

Be it known that we, HARRY A. CNMFER' and OWEN D. MCFARLAND, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvele-Strip-Making Machines,

ments in Shin of which the fq lowing is a specification.

' Our invention relates to machines for making shingle simulating strips.

. One of the objects of our invention-is to provide a machine for making shingle simulating strips of flexible material for roof covering and the like.

-Other, further and more specific objects of our invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings wherein Figure 1 is an end elevation of'the machine showing aroll of material of which the strips are made, broken away, to expose portions of the machine.

Fig. 2 is an end view, showin the end upon which the power wheel an the connecting and disconnecting clutch is mounted.

Fig. 3 is an elevation of the opposite side of the machine showing the train of gearing for connecting the various rolls and shafts together.

Fig. 4 is a transverse section taken. on line 4-4 of Fig.- 1.

Fig. 5 is a longitudinal section taken on line 5-5 of Fig. 3. Fig. 6 is a fragmentary section taken on line 6 6 of Fig. 3.

Fig. 7 is a similar section taken on line Fig. 8 is a longitudinal section taken on line 88 of Fig. 3 showing the slitting knives and the feed rolls.

the relative position of the parts.

Fig. 12 shows a sheet that has been cut into four shingle simulating strips and a transversely extending; punched hole that bridges the slits, locatedat uniform intervals longitudinally of the strips.

Fig. 13 shows a series of these shingle will appear when Fig. 15 is a modification of the structure shown in Fig. 13,made with the strips 14.

Fig. 16 is a sheet cut into four strips from which a roof resembling that shown 1n Figs. 13 and 15 may be constructed by alternately reversing in Fig. 17.

/ Fig. 17 shows said strips assembled.

In allthe-views the same reference characters are employed to indicate similar parts. Y

The material of which our'shingle simulatin'g strips are preferably made consist of afelt fabric 12 treated with, asphaltum or the like, and preferably covered on at least one side with flaky slate, or similar material and wound upon rolls 13 upon a shaft 14.

The machine consists of two side frames 1515', which are substantial duplicates. The side frames are held together by a suita'blenumber of bolts 17 secured in place by the nuts 18. Spacing tubes, or pipes 19, are placed over the rods 17-17' as a con the edges of the strips,.as shown venient means for holding the side frames 1515' parallel. A pair of brackets 202Q' are secured to one end of the frames 1515' for thesupport of the roll 13. Beams 2121 extend between the side frames 15-45 and are preferably T shape in cross section, having their flat top surfaces uppermost, which serve as tables for the support of the fabric 12 as it passes between the various rolls androtating punches and dies. The beams are secured to the side frames at each end by screwsor bolts 22 and cooperating nuts 23.

Extending between the side frames 15-15 are the parallel shafts 24 and 25. The

shaft 25 is supported in. relatively stationary bearings 2626'-, one in each frame, the shaft-24 being supported at each end in vertically adjustable bearings 2727'. hand wheels 28-28 serve as means for vertically adjusting the relative positions of the shafts 24 and 25 man obvious manner.

Each of the bearings 27-27 carries a screw threaded stem 29-29 which projects into a The sleeve -30, which is screw threaded at its lower end and which is secured to the respective hand wheel 28-28. The r'otation of the hand wheels 2828 serves to raise or lower the respective ends of the shaft 24 in adjusting it in position with reference to the shaft 25. The bearings 2727 have outersquared surfaces adapted to be vertically moved in guideways 31 provided' in the respective housings, or side frames. Each of the shafts, 24 and 25, is provided near its respective end, with a collar 32 that may be secured to the shaft in adjusted position, preferably against the respective boxes in which the shafts are supported by a screw 33, to prevent axial movement of the shaft. The shafts 24 and 25 are connected together for driving relation by the geared pinions 34 and 35, as by keys 36. These pinions are of the same diameter and contain the-same number of teeth and therefore the shafts 24 and 25 preferably rotate at the same speed. Mounted on the shafts 24 and 25 are cotiperating feed roller sections 37 and 39 rotatably held in place by feathers that are included in a spline which extends between the bearing ends of the respective shafts. On the shaft 24 is mounted a series of diametrically divided, rotary disk knives 40, of which there may be any desired number, each knife, for convenience of removal and replacement, is divided into two parts 40 and 40 more clearly shown'in Figs. 10 and 11. Each of the knife sections, 40 and 40 is secured to a sleeve 42 and betweenthe flange 41 of the sleeve and a separable fiat ring 43, by means of bolts 44 and cooperating nuts 44. This particular feature is cut and is counter bored, as at 48, to permit the sleeve 46 of the member 47 to enter the counter bore so as to bring the surface of the feed roll 37 into closer approximation with the respective knife. The fabric 12 of the roll 13 is fed directly to the knives 40 by means of the feed rolls 37 and 39 which knives slit the fabric into the desired number of strips, as shown in Figs. 12

. to 17, inclusive, as desired and depending upon the numberof knives mounted upon the shafts 24 and 25. The strips so slitted are then passed over the table 21 to the r0- tary punches which punch transversely extending slots or apertures that bridge the adjoining edges provided by the slitting knives and which may also punch slots into the moving fabric inwardly of the outer boundary thereof, as shown in Fig. 16.

Mounted upon the shafts 50 and 51 are the rotary punches 52 and a coacting drum 53, respectively. The shaft 50 is supported in relatively stationary bearings 54 and 54 and the shaft 51 is supported in relatively adjustable bearings 55 and 55, adjustable in the same manner and for substantially the same purpose as the shaft 24 by similar wheels 5656. The punch carrying shaft 50 is driven from the power shaft 57, which is supported in bearings 58 and 58 of the side I punches 64, and associated with each punch is a recess 65 in the drum structure to receive the parts punched from the fabric and to permit the same to fall away from the punch, as clearly" shown in Figs. 4, 5 and 9. Each of the punches 64, is secured to the drum by screws 66 so that the punches may be removed, sharpened and replaced or new punches provided. The shape of the punch and the arrangement shown in the machine, with the number of knives and punches indicated, will produce the fabric shown in Fig. 12. To produce the particular strips shown in Figs. 14 and 16, and othervarieties it is only necessary to change the shape of the punch and vary the positions and number of knives and punches required. The drum 53 is provided with removable wearing plates 68 and 68', of which there may be a suitable number and which are preferably made of a better metal than the body portion of the drum, and may be removed and replaced by means of screws 69. These plates form the abutments for the fabric when the punches 64 are brought into contact therewith and by this means cotiperate with the punch to'produce the aperture in the fabric as it passes between the punch and drum. The punches engage the under side of the fabric which is not covered with the slate or the like, and push the covered side into contact with the superposed drum.

Pieces of relatively thin sheet metal, 70,

70 are placed on either side of the axis of the shafts 50 and 51 to support the fabric as it passes in between and out. from the punches and cylinder die. Each of these pieces is provided with a vertically extending part 71 -71 and is ad ustable trans- Versely of the fabric so that the parts 7171' will support the fabric and prevent the ships that have been separated from the sheet by the slitting knives from separating from each other as they pass between the punch and die. The plates 7070' are so arranged that the vertical portions 71-71 may be brought into contact with the outer selvage edges of sheets of fabric of various widths.

Just about thetime the fabric is being properly longitudinally severed, by the slitting knives and punched at proper intervals by the punches and dies it passes be tween the guides 71' and over the table 21' I into and between the feed rolls 73 and 74,

' The shafts 75 and 76 are connected together by 'meansof geared pinions 82 and 83, of substantially the same .diameter and containing the same number of teeth, which are held on their respective shafts by" a key 84. The shafts, 75 and 76, are driven by these pinions and an intermediate gear wheel 85,

supported on a stud 86 that projects from the frame 15. The intermediate gear 85 is driven by the gear. wheel 61. A snnilar intermediate gear wheel 87 is mounted upon a stud 86 and serves to drive the gear wheel or pinion 35, itself being driven by the-gear wheel 61.

Rotatable upon the power shaft 57 is a power wheel or pulley 90 which is adapted to be secured to the power shaft to drive the machine by means of a clutch 91, operable by the handle-92.

A housing 93 covers the train of gearing on one side of the machine and a similar housing 94 covers the train of gearing on the other side of the machine. These housings protect theoperator from danger ofthe intermeshing gear wheels.

' By the use and operation of our machine.

as illustrated the. sheet 12 fed continuously from the roll 13, is divided into four strips 12*, 12", 12 and 12. The strips 12 and 12" are separated by a slit 95 and this slit, which extends longitudinally of the strip is bridged by transverse slots 96 which are made before the strip is completed and which may be of the form shown in Fig. 12 or 14, or of any other similar and suitable design. These slots are spaced at regular intervals or distances and when the .have been made therein.

strips are separated the lower portion of them, between the slots, simulate the appearance of shingles, as shown in Figs. 13, 15 and 17, one strip bein laid and lapped upon another, just as the lingles are separately placed in position. The transverse slots 96 of the strips provide kerfs or spaces between adjacent shingles.

If it is desired that the projecting ends or shingles shall take the form shown in Fig. 15, then the punch for producing the slot 96 should have a rectangular enlar e ment, asshown in Fig. 14. To divide {U113} cent strips they are cut apart, as at 97, this cleavage being through a continuous portion of the fabric and not across perforations, or transversely extending slots, that Another form of strip isshown'in Figs. 16 and 17 wherein either edge, 98 or 9.9, may be turned down and exposed to the weather. In this structure transverse slots. 100 are punched between adjacent strips and on the selvage edge of the sheet.

It will be observed that in the operation of our machine the sheet and strips are continuously in motion;' that the sheet is first sl'itted longitudinally to-subsequently provide as many strips as required and then simultaneously punched at intervals, the slots, or' perforationsthus provided breaking the otherwise lon 'tudinally continuous edges of the strips an finally the strips are passed from the machine, this cond1t1on, ready to be divided into suitable lengths.
