MACHINE FOR MAIKING PREPARED ROOEING.

Aptiiation mea February 2o, 1924l serial No. 694,084.

This invention relates to improvements in machines particularly adapt-cd for use in the manufacture ofpre'pared roofing, espec ially strip shingles, andmore .particularly relates to such machines adapted for use in separating aweb of `prepared roofing ma.-

terialinto strips or elements fornse in covering the roofs or'walls of buildings, such strips preferably being formed with spaced tabs or projections, which will, when the strips arelaid in overlapping rows, simulate the appearance of ordinary shingles or tile.

The rparticular object of the invention isv to provide a machine of the above character, having means for longitudinally and transversely scoring or partially cutting the inaterial to form strip shingles, such scoring or cutting being sufficiently de ep to permit the shingles to be readilyseparated from one another.

A further object is. to provide a machine i from the following description and' the accompanying drawings and will be pointed out in the annexed claims.

In the drawings, there has been disclosed a structure designed to carry out the -various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown as various changes may be made wit-hin the scope of the claims which follow.

In the accompanying drawings forming a part of this specification:

Figure 1 is a vertical sectional view of a machine embodying my invention;

Figure 2 is a plan view of Figure 1;

Figure 8 is an enlarged detail View of the scoring roll removed from the machine, showing the preferred method of mounting the slotting dies and scoring knives thereon;`

packed into bundles for'convenience 1 Figure 4 is a detail view of one end of the roll, i

Figure 5 is a -cross sectional View on the line 5 5 of Figure 3; Figure 6 is a plaiiview of shingle material, the dottedl lines indicating how it is scored' by passing between the rolls of themachine;

Figure 7 is a view showing how the material is preferably separated into sections after having been scored;

Figure Y8 is an enlarged view of a completed strip shingle; and l Figure 9 is a' perspective View of one of the slotting knives detached from the roll.

In the selected Yembodiment of the inVention here shown there is illustrated a inachine comprising a frame 11 having an inclined table 12 mounted thereon over which a sheet or web of roofing materialA is fed to a pair of rolls 13 and 14 mountedl on shafts lf3 and 1G, respectively, which are rotatably mounted in suitable bearings borne by the frame 11. The lower or driven roll 14 has a plurality of scoringknives mountedin the periphery thereof, adapted to cooperate with /the peripheral surface of'the upper or pressure roll 13 to score thema.-

terial Aas it is passed therebetween.

As'shown in Figures 3, 4 and 5, a series of sleeves 17, 18, 19 and 21 are mounted on .the scoring roll 14 and these sleeves constitute the periphery of the roll when in assembled position. Circular knives 22 are concentrically mounted on the roll between adjacent ends of thesleeves 17-18, 1819 and 19 and 2l. Collars 23 are provided at each end of the roll and are preferably in threaded engagement therewith so that the slee-ves and circular knivesv22 may be securely clamped together. These knives function to longitudinally score the web of rooting material as it is passed between the rolls 13 and 1&1. They may be formed as shown to score or cut straight lines as in,-

i dicated by the dotted lines 24 and 25 in Figures 6 and 7, or, if desired, one or more of the knives may be shaped to cutan irregular or siiiuous line while another knife may be cutting or scoring a straight line.

In the manufacture of strip shingles, such as that shown in Figure 8, it is desirable to form tabs or butts 26 on the projecting edge thereof so that when the shingles are laid inl overlapping rows .they Will simulate the appearance of ordinary, shingles or tile. To

. form these butts, open end slots or notches -edges of the sleeves 17 and 18, and the abutting edges of the sleeves -19 and 21, such sockets preferably being arranged in longitudinal alignment with each other, as shown.

.of substantially -When thus positioned, the adjacent or open ends of the slotting knives 28 will abut against the circular knives 22 interposed therebetween. The knives or punches 28 are secured in their respective sockets 29 preferably by means of suitable Wooden Wedges or blocks 31 which are driven into the hollow or central portions thereof when dry,

and when these wooden blocks become wet or water-soaked due to being continuously submerged in water as a result of the lower portion of the periphery of the drum 14 being partially submerged in a suitable liquid such as water, they will expand and Outwardly force the walls of the punch against the walls of the sockets 29. The above construction provides a very simple and inexpensive method of securing the slotting knives or punches to the drum.

Means are provided in each of the slotting punches to prevent blanks of roofing vmaterial from accidentally becoming lodged or wedged in the central portion thereof, which would cause the machine to become inoperative. Such means preferably consists in the provision of yieldable means, such as rubber pads 32, mounted in each punch and secured to {lr/e wooden block or Wedge 31. These yielda'ble pads are similar in construction to the usual ejector pads-ordinarily provided on a punch-press, and function to eject the material from the punch and thus preventing the machine from becoming inoperative.

Means are also providedf'for transversely yscoring or cutting the web of roofing material (as indicated by the dotted lines 33 in Figure 6) simultaneously as it is being longitudinally scored andA slotted, so that it may readily be separated into sheets capable of convenient handling.- Such means preferably consists in the provision of a plurality straight knives or blades 34 which are mounted in the periphery of the drum 14, preferably in longitudinal alignment with one series of the cutters 28, thus providing continuous cutters extending substantially from end'to end of the roll. As

shown in the drawings, the sleeves 17, 18, 19 and 21 are each provided with a longitudinal slot 35 extending preferably from the end of one of its knives 28 to the end of the sleeve, and into these slots the knife blades 34 are inserted. The transverse cutting blades 34 are preferably secured in place by means of wooden wedges. 36 `driven into the slots 35 'adjacent the blades 34.v

lVhen the roll 14 is provided with scoring or cutting' knives and punches, as above dcscribed, the web of roofing material, when passed between this roll and the pressure roll 13, Will be scored as shown in Figure 6. When thus scored four shingles Will be formed across the width of the web of roofing material; the dot-ted lines 25, 25, indicating the bottoms of the proposed shingles, and the dotted line' 24, and the side edges of the web, forming the tops of the shingles when separated from each other, as shown in Figure 8. By the provision of the spaced slotting knives or punches 28 in the periphery of the cutting roll7 the slots or notches 27 Will be cut or scored in the web of mate* rial transversely of the dotted lines 25-25, so that when the shingles are subsequently separated from one another the tabs or butts 26' will be provided in the lower portion `thereof substantially as shown in Figure 8.

The web will` also be transversely scored, as indicated-by the dotted lines 33 in Figure 6, these lines indicating the ends of the shingles and the juncture in the Web Where it is separated t-o form sheets, such as shown in Figure 7, which may conveniently be stacked into bundles of-suitable size for convenient handling. The shingles comprising each such sheet are preferably manually Separated from one another, and tied intosmall bundles before being shipped from the factory for subsequent laying.

The upper or pressure roll 13 .is mounted in suitable bearing blocks 37 preferably slid-ably mounted between upright vertical guides 38 secured to the main frame 11. Pressure is appliad to the roll 13 preferably by means of a suitable weight 39, adjust-ably mounted upon a bar 41 which has one cnd pivotally connected to a lixed bracket or standard 42. A rod 43 connects the bar 41 with one end of a similar bar 44 having its other end pivotally connected to one of (he upright guides 38. A comici-tion 45 is provided between the bar 44 and the bearing block 37. Thus, it will readily be seen that by the gravitational action of the weight. 39 the roll 13 will be yieldably the peripheral surface of the cutting or scoring roll 14. Such a weight is preferably vprovided on 'each side of the machine.

The lower or cutting roll 14 preferablv operable by means of a gear 46 secured to the shaft 16 thereof and adapted to be in` mesh with a pinion 47 mounted on a counheld against a suitable source of power, such as the mo# tor54. v i

In the practical operat1on of machines ot this type it has been found desirable to pro-v vide means for moisteningl the surface of the cutting roll in order to prevent the rooting material from adhering thereto.- Such nvans preferably consists in the provision of'a receptacle or tank 50 mounted directly beneath the scoring roll 14 and preferably supported by the main frame 11. This tank contains a suitable liquid such as water and is so arranged that the lower portion of the roll will be subn'iergedin the water (see Figure 2) thus saturating the entire surface thereof as it revolves.`

Means are provided. in conjunction with this novel shingle making machiney whereby the web of roofing material, after having been properly scored, will be separated into sheets for convenient handling, each such sheet preferably comprising a plurality of shingles as shown in Figure 7. To 'effect such sej'iaration of the scored web, theweb is passed from the rolls 13 and 14 onto a conveyor belt 55, preferably operable from the countershaft 4S by means of abelt 56 and a pair of gears 57. The surface speed of this conveyor is considerably greater than the peripheral speed of the rolls 13 and 14 and therefore of the web, 'as it is fed between the rollers and discharged therefrom.

As the. scored web is discharged onto the surface of the conveyor 55 it will continue to travel at the same rate of speed as the peripheral speed of the rolls 13 and 14 until brought into contact with a roll 58 arranged in slotted guides 59 above the conveyor and normally. rolling on the surface thereof. As the end of the web engages the roll S it will be pressed downwardly thereby against the surface of the conveyor belt 55, which will immediately grip the web and exert a pull thereon as a result of the frictional contact of the web between the surface of the conveyor and the roll 58, caused bv a relatively higher surface speed of `the conveyor'. 'lhe effect ot' the pull thusexerted upon the end of the web will cause it to separate at the juncture where it has been transversely scored. as shown in Figure 2.

The peripheral surface of the roll 58 is pref-4 erably covered with a suitable facing 61 to prevent slippage.

The conveyor belt is preferably sup ported b v an adjustably mounted frame 62 having rollers 63 provided at the ends thereof over which the conveyor belt 55 passes. @ne end of the conveyorframe 62 is pivotally connected to the main frame 11 `and the outer end thereof is adjustably supported by means` of a suitable cable 64, having one end secured to-the frame 62 and upwardly passing therefrom over a sheave (S5 and having a suitable weight 66 secured to the depending end.thereo.f. Thus,` the discharge end of the conveyor may readily and quickly Ibe adjusted to the proper height. A rack 6T may also be provided to receive the separated sheets of rooting material, as shown in. Figure l.

In the drawings I have shown the cutting 'or scoring roll 14 provided with knives adapted to score the web as shown in I1`iguref?. It is to be understood. however, that various sizes and combinations of knives may be substituted for those shown, as for instance, the outer circular knives 22 may be axially curved or irregularly shaped so as to produce curved or sinuous lines instead of the straight dotted lines 25. 25, shown in` Figure 6. The knives may also be arranged in the roll 14 in such manner .as to adapt the machine for use in scoring different widths of material.

In place of scoring a double width web of material to form four strip shingles, as shown, I may use a single width strip to form a single pair of shingles in which case. the center knife 22 and one of ythc end knives 22 will be omitted and only one of the knives 22 with the co-operativev scoring knives 28 will be employed.

I claim as my invention:

1. In a machine of the class described, a frame, a lower ioll journaled in the frame and an upper roll normally resting on the lower roll with means to adjust the pressure of the upper roll against the lower roll, the lower-roll having knives therein arranged to score the material passing between the rolls, and means beyond the rolls to clamp the material and completely severA it on the scored lines and deposit it in separate sheets.

2. In a machine of the class described, the combination. of "a frame, upper and lower rolls, the lower roll having cuttingknives and being journaled in the frame, the upper rol-l `having connected thereto adjustable means to force it towards the lower roll .whereby the pressure on the material passing lthrough the roll may be varied so as to only score the material, without cutting through the same and means for exerting a pull on the material after it has been scored to completely separate the material into separate sheets.

` 3. In a machine of the class described, the combination of an upper and a lower roll, the upper roll being journaled .in bearings slidably mounted in upright guides, a bar pivoted atl one end to a guide with connections to the bearings, the other end of the bar having downwardlyextending connections and a weighted lever with itsweigllt adjustable to adjust the pressure on the upper roller bearing, the lower roll having a series of sleeves 'arranged thereon with scoring knives between the sleeves, a tank into which the lower roll extends, and means to one side of the rolls adapted to separate the material passing between the rolls into sheets.

4. In a machine of lthe class described a roll with supporting means therefor, sleeves on the roll having sockets provided in the adljacent edges of said sleeves, U-shaped knives arranged 1n said sockets, and wooden blocks arranged between the legs of the U-shaped 15 knives.

5. In a machine of the class described, a roll with supporting means therefor, sleeves on the roll having sockets vprovided inthe adjacent edges of said sleeves, U-shaped knives arranged in said sockets, Wooden blocks arranged between the legs of the U-4 shaped knives, and rubber pads on the exterior of the blocks for ejeeting the severed lportion of the cut article.

' In witness whereof, I have hereunto set my hand this 14th day of February, 1924.
