Specification of Letters Patent. Application led June 26, 1907. Serial No. 380,855.

Patented June 23, 1908.

To all whom it may concern:

Be it known that I, FREDERICK C. OVER- BURY, of New York, in the county of New York and'State oi New York, have invented certain new and useful Im rovements in Maqe-Strips, '&c., of

which the following isa speciiication. This invention relates to machines for forming a lon 'tudinal cut between the 'edges of a web or s eet'of iieXible material, such as that employed. for coverings of roofs and walls of buildin s, and usually .denominated roofing materia?. -v

The invention has especial reference to means for making a zig-zag lon itudinal Cut, which divides a web or sheet fooling malterial into two rooiing strips, each having a serrated edge. composed of alternating tongues and recesses. When the strips are laid upon a roof, the serrated edges are eX- posed, and give the roof a desirable diversipointe ed apcpearance similar to that produced by shingles. 4 The invention has Jfor its object first vto 'provide a'simple and eifective'machine for making a zig-zag longitudinal` cut in 'a' sheet or web of rooiing material, the machine having suitable provisions for compensating for wear of the parts or members of the cutting apparatus.

The invention also has for its object to enable the longitudinal cut to 4be interrupted at intervals, to the end thlat the two serrated strips formed by the longitudinal cut, may

not be entirely separated. from each other,

' but will be connected at intervals b luncut portions of thesheet or web, so that t e sheet or web, .as a whole, may befwound intp a roll or coil whichis Composed of two nearly inde-4 endent serratedrooiing strips which are ocked to ether by the uncut portionsl of the sheet, so t at the tongues of one strip occupy the recesses between the tongues of the other strip in the coil or roll, the tongues of 'both strips being thus protected and prevented from distortion and injury, while the coil is in storage ortransit.

The vinvention Consists. in the several improvements which I will now proceed to describe and claim.

Of the accompanying-dra `ngs, forming` a part of'this s ecification,-Figure 1 represents an ende evation of a strip-cutting machin'e embodying my invention. Fig.'- 2`represents an elevation of the endfv of the machine opposite that shown in Fig. 1,.` Fig. 3 represents a rear elevation of the machine shown in Figs. 1 and 2. Fig. 4 represents a side view of a portion of a sheet or web illus trating the method of forming vthe'zig-zag .cut therein. Fig. 5 represents a side view oi a longer portion of the web showing inter- Vsides of which constitute guides for movable bearings 15 16 which are movable vertically in the openings 1 4. In the bearings 15 are journaled the end portions of a loose or idle shaft 17, to which is aiiixed an idle bed roll 18, preferably made of aper or otherwise dense fibrous material, a apted to coperate with the cutting knives hereinafter described.

Inthe bearin s 16 are journaled the endportions of a sha t 1 9, towhich is aflixeda carrier roll 20, the latter constituting a support for the idle bed roll 18. The shaft ofthe carrier roll is positivelydriven by gearing; hereina'fter described, Connecting said shaft with the driving shaft 21, and is supported with the carrier rollpreferably in such manner thatthe carrierroll maybe adjusted vertically to compensate lfor wear of the bed roll caused by the action of v,the cutting knives,` hereinafter described, 'pn the pe'- riphery of the bed roll. yThe means here shownfor adjusting the carrier roll 20 .com-

prise vertical;"screw-threaded shafts 22 en rier roll shaft are supported by the screw shafts 22, and are raised and lowered by adjustments of the. latter. simultaneously'o erated by means of a shaft 25, journaled in earings on the supporting frame, and provided with worms 26 engaging thev worm teeth of the nuts 23. The shaft 25 may be rotated by means of a hand The nuts 23 arey wheel 27, rotatably mounted `on the frame of the machine, a sprocket wheel 28'afiixed to the hub of the hand wheel, anda sprocket chain 29 connecting the sprocket wheel 2S with a sprocket wheel 30 aiiixed to the shaft 25. I employ a plurality of cutting knives 33, which are arranged to cooperate with the periphery of the rbed roll in forming a longii tudinal zig-zag cut 31 Vin a web or sheet 32 of roofing material, as shown in Fig. 5. The said knives are preferably arranged in-two series, and on two rotary Acarriers 34 having axes of rotationwhich are parallel with the axis of the bed roll, said carriers being located above the bed roll, and on opposite sides of the vertical plane of the axis of the latter,

as shown in Figs. l and 2. The said carriers 34 are preferably hubs or collars affixed to shafts 35 which are journaled in bearing blocks 36 located in openings in the upper portions of the sides of the supporting'frame,

the said shafts and the carriers being positively located by the gearing hereinafter described. The knives 33 oneach'carrier are `inclined or obliquely arranged relatively to the axis of the carrier, the knives of one carrier being inclined in one direction, while the` knives of the other carrier are inclined in the opposite direction, the arrangement being such that the knives of one carrier form a series of parallel cuts a: (Fig. knives of the other carrier orm a serles of parallelcuts y, said cuts uniting to form the zig-zag cut 3l shown in Fig. 5. The cutting edges of the knives are of segmental contour, all parts of each cutting edge being an equal distance from the center of the carrier cn which it is located, so that each cutting edge cuts progressively through the Web or sheet, all parts ofveach cutting edge coming to a bearing on the periphery of the bedroll.

The cutter-carrying shafts 35 are positively rotated in unison, and in the same direction, by the mechanism next described. The driving shaft 21, to-"which is aiixed a driving pulley 37 engaged with a. driving belt or otherwise driven, is rovided with a small driving gear 38 -mes ng with a relatively' large gear 39 affixed to one of the end portions of one of the knife-carrying shafts'35. l To the opposite end of the same-shaft is affixed a smaller gear 40, meshing `with an intermediate gear 41, which in turn meshes with a gear 42 of the same size as the "gear40, andl affixed to the other knife-carrying shaft 35.

The described caring causes the simultaneous rotation of the two shafts 35 and the knife-carriers thereon. .g f j The carrier roll 20 is rotated byrneans of the above-described gearing, and 1n addition thereto a gear 43 meshing with the gear-42, a smaller gear 44 meshing with the gear 43, and an intermediate gear 45 meshing with the gear 44 and with a gear 46 affixed to the shaft 19 of the carrier roll.v The carrier roll 4),' wh'ile the is thus rotated in the direction required to cause it to rotate the idle bed roll by friction in conformity to the rotation of the knife carriers, as indicated by arrows in Fig. 2.'

The above-described mechanism for driving the carrier roll has provisions for com'- pensating for the vertical adjustments of the carrier roll, which are made to compensate for wear of the 'latter and of the knives. Said provisions, as here shown, are embodied in an arm 47 mounted to swing on the shaft 48, which supports the gear 43, said arm having'a segmental slot 49, through which pass set screws 50 engaged with the supporting frame, said screws being adapted to support the arm 47 in different positions. AThe'gears 44 and ,45 are mounted on the arm 47. When it becomes necessary to adjust the carrier roll upwardly or downwardly, the arm 47 is given a corresponding adjustment to maintain the proper engagement between the gears 45 and 46.-

The web or sheet to be out is passed bee tween the idle Aroll. and the two knife car- The knives of the first carrier form the parallel cuts m (Fig. 4), and when these reach the second carrier, they are connected by the parallel cuts y `formed by the knives of the second carrier. The cut is therefore comlete in the portion of the lstrip that passes om the second carrier to the nip of the bed roll and the carrier roll. The strip maybe guided from the machineV after passing the said nip by any suitable means.

To provide for 'an interruption of the cut at stated intervals, and thus'form connecting portions 51 which temporarily connect the two serrated strips together, as shown'in Fig. 5, I have equipped the machine with mechanism for moving one of the knife-carrying shafts 35, and preferably the' shaft of the first carrier, away from the bed roll suiciently to lift the knives carried by that shaft out of contact with the web or sheet for a brief period', the knives being immediately returned to their operative engagement with the bed roll. The mechanismffor acconn plishing` this resultas here shown as follows: 52 represents a rock shaft journaled in bearings on the frame above thebearings of 'the st knife-carrying shaft 35, and connected with the bearings 36 of said shaft by` means of short arms 53 affixed to the rock shaft, and links 54 connecting the arms 53 with ears on the 'bearings 36, said bearings being vertically 'movable in openings in the supporting frame. vided with 'another arm 55, to which is joint- The rock shaft 52 is proed the lupper end of a liftiiig barL 56., said bar l mechanism is so timed that the lifting bar is being provided Withfa coupling member 57, raised, and the knives on the shaft 35 withA here shown as a recess formed in oneedge of the bar.

shaft 48, 'which-supports., the gear'43 and swinging arm 47. vided with a trundle ioll or stud 62, W ich enters the cam 61, thelatter being formed to swing the lever 58,- upwardlyand down? wardly, .the lever'beiig'givena downward lmotion and an upward motion'once during `each rotation of the shaft 4S. The lifting bar 56 is normallymheld out of engagement -4 with the coupling member 60 on the lifting lever, andis riefly thrown into engagement with said lever by an edgewise Ymovement which causes the coupling member 57 to rey ceive'the coupling member 60. WhentlS takes place, the described upward and down-l ward movements-fof the lifting lever will be imparted to the lifting bar, causing the latter to first raise the knife-carrying shaft throughthe rock shaft 52 and the describedconnections, thus lifting the knives carried'by that shaft from )the bed roll until a short length of the web or sheet has passed uncut, the lifting bar being. then moved downwardly', andy caused to return the knives carried by the shaft 35 to their position engage-mentwith the bed roll. The lifting lever isengaged 'with and disengaged froinmtfie lifting bar by means of a trip cani 63, which is mounted to rotate on a short lshaft 64 journaled in bear- 'i ings in one of the side pieces of the supporting 1 frame, the said shaft being provided with a worm gear 65 meshing with aworm 66 affixed' toan inclined shaft 67which is journaled in suitable bearings on the supporting frame, and has at its upper end a bevel gear 68 `meshing with a bevelgear 69 aflixed to the Provision 1s thus' made for impart-- inOr to the tiip cam a relatively slow rotationshaft 48.

Vthen the offs'rt or concentric portion of said g cam, shown in Fig. 1, reaches a trundleroll 'lpendent lever 71, which is pivoted at 72 to t e supporting frame, it swings" said lever to the eft, as viewed in Fig. 1, thus causing a link 721 connecting the lever 71 Vwith, the lower end `of the lifting bar 56 to The lifting lever 58 is ro whichit is connected, are made inoperative, aftei' a length ofthe web or sheet sufficient to form one roll has been provided with a con-A tinuous zig-zag cut, the cut being then interrupted briefly, leaving'the connecting portion 51 which occurs 'at the point where the I web or sheet-is to be severed into roofing strips. i

-The arrangement of the cutting knives in two series on separatecarriers, one 'series forming arallel cuts inclined in one directoi convert it tionfwhi e the other series form parallel cuts extending in the opposite direction, is preferred by mebecause it simplifies the coristruction of the knives, each knife beinga flat blade, which .is adapted to bev adjustably secured to the carrier by screws passing through slots 7 5v in the blades,` the screws engaging the bladesupporting arms on the carrier.y If both series ofblades were arranged on one carrier, 'there would be more or less difficulty in the proper joining of the ends .of the blades to form the angles of the zig-zag cut. So far, however, as features of the machine not necessarily dependent on this arl rangement of the cutting knives is concerned,

the construction may be varied, and all the knives arranged on one carrier without departing from the spirit of the invention.

I do not limit myself to the details of the. svame may be variously modified.
