This'application is a divis onfrom the ap plication for shingle-strip making machines filed January 2, 191;, and indicated by Serial N0. 249.

. "While our method of making shingle-simulating strips may be; accomplished withat the aid ofa machine, it will be more readily understood in connection with the description of a machine that is readily gd'alpted for carrylng the method into. efec r The materialof'which our shingle-simulating strips are, preferably, made, consists of felt fabric 12, treated with asphaltum,

or the like, and preferablyfcovered on at least one side, w1th flaky, vitreous or mineral material, such as slate or the like and wound ber of bolts 17 secured in place by nuts 18.

Spacing tubes, or pipes 19 are placed over the rods 17:17 as a convenient means for holdlng the side-frames 15-15" parallel, A

pair of brackets 2O -20' are secured to one end of the frames 1515 for support of the shaft 14 carrying the roll 13. Beams 2121 extend between the side frames 15-l5f and are preferably T-shaped in cross section,'

having their flat top surfaces uppermost, which serve as tables for support of the fabric 12, as it passes between the various rolls and rotating punches and dies. The

beams are secured to the side frames at each end by screws or bolts 22 and cooperating nuts 23.

Extending between the side frames 1515 are the parallel shafts 24'and 25.-

The shaft. 25 is supported in relatively stationary bearings 26,26-, one on each frame, the shaft 24 being supported at each end in vertically adjustable bearings 2727. The hand. wheels 28,-28- serve as means for vertically adjusting'the relative position of the

shafts

24 and 25 in an obvious manner. The rotation of the

hand wheels

28, 28 serve to'raise or lower the respective, ends of the shaft 24 in adjusting it in position with reference to the shaft 25. The

bearings

27, 27 have outer squared surfaces adapted" to be vertically moved in guide ways '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 these shafts .are supported by a screw 33 to prevent axial movement of the shaft. The shafts 24;and,

side

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 cooperating

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 Each of the knife sections 40 and 40 is secured to a sleeve 42 and between the flange 41 of the sleeve and a separable flat ring 43, by'means of bolts 44. This particular feature of our invention is disclosed and specifically claimed in a prior Patent No. 1,107,762 granted to Harry A. Cumfer, on the 18th day of August, 191.4, and therefore is not subject matter for claims in the present ap plication.

A series of knife members 45 contact one with each knife 40 and are located on the parallel shaft 25. Each consists of a sleeve 46 having a radially extending flange 47,

' which abuts the side of the cutting edge of the knife 40. Each pair of the feed rolls 37, 39 is adapted to'feed the individual strip into which the sheet is cut and is counter-bored, to permit the sleeve 46- of the member 47 to enter the counter+bore so as to bring the surface 47 of the feed roll 37 into close 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 fabricinto the desired number of strips, as shown in Fig. 5.- There may be as many strips as there are suitable knives mounted upon the

shafts

24 and 25. The strips so slit are then passed over the table 21 to the rotary 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.

Mounted upon the

shafts

50 and 51 are rotary punches 52 and a coacting drum 53, respectively. The shaft 50 is supported in relatively stationary bearings and the shaft 51 is supported in relatively adjustable bearings 55, 55, vertically movable in the same manner and for substantially the same purpose as the shaft 24, by

similar wheels

56, 56. 'The punch-carrying shaft 50 is driven from-the power shaft 57, which is supported in bearings 58, 58 of the side frame by means of a geared pinion 59 which meshes into a gear wheel 60 carried by the shaft 50. The shaft 51 is driven by the geared pinions 61 and 62 of the same diameter, and having an equal number of teeth, so that the

shafts

50 and 51 will be rotated at the same speed; the geared wheels being secured to the respective shafts by keys 63. The rotatable drums 52 which carry the separable hollow punches 64 are hollow, or carry interior recesses. Each of the drums, in the exemplification is provided with four hollow 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 Fig. 3. 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. 5. To produce fabrics havmg perforations of different shape, punches of various configurations may be used and it is only necessary to change the shape of the punch and to vary the positions and numbers of the knives and punches required to change the general form of the strips. The smooth face drum 53 is provided with removable hardened wearing

plates

68, 68 of which there may be a suitable number and which are preferably made of better material than the body portion of the drum, may be re-- moved and replaced by means of the screws 69. These plates form the abutment for the fabricwhen the punches 64 are brought into contact therewith and by this means cooperates with the punches to produce apertures in the fabric as it passes between the punches and drum. The punches engage the under side of the fabric, which is not covered with slate or the like, and push the covered side into contact with the superposed smooth surface of the 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. pieces is provided with a vertically extending

part

71, 71 and is adjustable transversely of the fabric so that the

parts

71, 71 will support the fabric and prevent the strips 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 70 and 70 are so arranged that the

vertical portions

71, 71 maybe brought into contact with the outer selvage edge of the sheet of fabric of various widths. 1 Just about the time the/fabric is being Each of these properly longitudinally severed or slitted by 4 the slitting knives and punched at proper intervals by the punches and dies it passes between the

guides

71, 71 and over the tables 21, 21 into and between the feed rolls 73 and 74, which are mounted upon the shafts 75 and .76, respectively. These feed '75 I is supported in vertically adjustable mediate gear 85 is driven by the gear wheel 'theother side of the machine. These housbearings. The

shafts

75 and 76-. areconnected together by means, of 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 keys 84. .The

shafts

75 and 76, are driven by these pinions and an intermediate gear 85 supported on the stud 86 that projects from the frame 15,. the inter- 61. A similar intermediate gear wheel 87 is mounted upon a stud 86 and serves to drive the gear wheel and pinion 35, itselfbeing driven by the gear wheels 61.

Rotatable .upon a power shaft '57 is' a power wheel or pulley '90, which is adapted to be secured to the power shaft to drive I the machine bymeans of a clutch 9'1 operated'by the'handle 92.

- Ahousing 93 covers'the train' of" gearing on one side ofthe machine and a similar housing 94 covers the train-of gearing on ings protect the operator from danger of intermeshing gear wheels.

By the use and operatlon of the machine, as illustrated, thesheet 12 is fed continuously from the roll 13,. and is divided into 1 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 any desired form within the contemplation of our,

method of makingshingl'e simulating sti'i s.

The perforations 96 of the strip provides kerfs or spaces as between adjacent shingles. It will be observed that to hasten the operation of our method of construction the sheets and strips are continuously in motion; that the sheet is first slitted longitudinally to .subsequently provide as many strips as is required and'then simul-.' taneously punched at intervals, the slots or perforations thus provided breaking the otherwise longitudinally continuous edges of the strip and finally the strips are pas'sed from the machine, in this condition, ready rying our invention into effect, it is manifest to persons skilled in the art that our method "of making shingle-simulating strips is not dependent upon a machine of any particular construction as it may be carried intoeffect by hand manipulation but not so rapidly or so cheaply as when a machine is used for avmg described ourinvention, what we of them, be-
