' weather=proof sheet, the latter being adapted for Patented May 7, 1935 UNITED STATES PATENT OFFICE 2,000,077 APPARATUS FOR AND METHOD OF APPLY- ING SURFACING WEB MATERIAL l'0 A FABRIC Application November 3, 1930, Serial No. 493,033 23 Claims. (Cl. 91-18) This invention relates to improvements in apparatus for and method of applying surfacing material to a fabric web.

In the manufacture of composition roofing, a is saturated with bituminous material, such as asphalt, and is then coated with a like substance and with a layer of crushed slate or other mineral to produce a use in either roll or strip form, and also being adapted for cutting into individual elements each of a desired shape. Heretofore, considerable difficulty has been encountered in properly and efllciently applying the asphalt and crushed mineral to the felt base. This has been particularly true where it is desired to utilize crushed mineral of different colors to create contrasting effects or designs upon the roofing.

I. is, therefore, one of the objects of this invention to provide an improved apparatus and method for cutting and surfacing a fabric in a minimum period of time, and in an eflicient and effective manner.

. A further object of this invention is to provide an apparatus and method of the class described which is adapted to deposit crushed surfacing material of different colors on a receiving means, with the various colors" arranged in a predetermined manner to create a desired efiect or design. A more specific object of this invention is to provide an apparatus embodying a discharge hopper having mineral material arranged therein in strata of different colors, the said hopper being adapted to discharge said strata on a traveling web or intermediate receiving means, the arrangement of the strata in the hopper determining the effect which will be produced on "the finished roofing material. 1

A further object of this invention is to provide an improved apparatus for applying surfacing material to a fabric web, in which a rotatable intermediate receiving means for the crushed mineral may be utilized, said means being adapted to transfer the mineral from the hopper to the traveling web, and to deposit the mineral on said web in the same color arrangement as deposited by the hopper.

With the above main and other incidental objects in view, the invention consists of the improved apparatus for and method of applying surfacing material to a fabric web and all parts and combinations as set forth in the claims, and all equivalents thereof.

Referring to the drawings, the numeral designates a supporting frame having upstanding side portions 26 and 21, and the numeral 28 designates supporting brackets which are spaced from the frame. A shaft 29 is journaled in bearings mineral discharging hoppers 40 and to the other side a hopper 4| for discharging liquid asphalt or other bituminous material. A shaft 42, journaled adjacent the discharge openings of the hoppers 40 carries rigidly mounted grooved rollers 43. The function of said rollers and the remaining details of construction of the hoppers 48 will be hereinafter described in detail.

The shaft 42 is driven through the medium of an endless chain or belt 44 which is in connection with the shaft 29. 'The shaft 42 in turn imparts.

motion to a grooved roller 46, mounted in the discharge portion of the asphalt hopper 4|, through an endless chain or belt 46.

Brackets 41, in suitable connection with the frame, are arranged to support a roll 48 of the saturated felt or other fabric which forms a base for the roofing material. The felt is arranged to be guided from said roll beneath the discharge opening of the hopper 4|, between rotatably mounted squeeze rolls 49 which gauge the thickness of the coating, around a rotatably mounted heated roller 50, back over the tractor belt, beneath a roller 5| and over a roller 52. A pan 53 is suitably mounted between the rollers 60 and 5| to catch surplus asphalt which may fall off the edges of the felt.

From the roller 52, the felt is arranged to pass in S-formation around cooling drums 54 and 55, beneath a roller 56 and between rollers 57 and 58, the latter roller being provided with knives 59 for severing the web at desired intervals. The drums 54 and which contain some type of cooling fluid, are mounted on shafts 60 and 6| which are suitably Journaled in the upstanding frame portion' 26, and the shaft 6| may be driven through a sprocket wheel engaged by an endless chain 62, the latter being connected to a suitable source of power. The rollers 51 and 58 are mounted on shafts 63 and 64 which are 'journaled in the upstanding frame portion 21. The cutting roller 58 is driven by an endless chain 65 which passes around a sprocket wheel on the shaft 64.

In order to press and support the surfacing on the outer surface of the web as the latter passes around the drum 54, an endless belt 66 which rotates around rollers 61 and 68, is arranged to engage said surface of the web. Said belt 66 is maintained firmly against the web by a weighted belt tightener 69.

Mounted beneath the tractor belt is a spraying device 10 driven by a suitable motor II for spraying a parting substance such as liquid calcirnine, glycerine, or liquid mica on the platens 34 to prevent the asphalt from adhering to said platens. A drier I2, mounted adjacent to the spray, and driven through a suitable connection with the latter, is adapted to blow cool air upon the platens for cooling purposes and for partially drying the parting liquid. A rotatably mounted brush l3, which may also be driven through a suitable conmotion with the motor H of the spray, is positioned to engage the projections 35 of the platens to clean the latter.

In Fig. 3 a modified form of apparatus is illustrated in which the hopper 40 discharges directly upon the traveling web. In this form, the fabric 48 is unwound from a roll, passed through a tank 74 containing a liquid saturant, between heated drying rolls 15, beneath a hopper 4| which deposits a coating of bituminous material on the upper surface of the web, beneath the crushed mineral hopper 40, and around cooling drums 54' and 55.

The hoppers 40 which are utilized in the apparatus shown in both Figs. 1 and 3, and which form an important part of the invention, are illustrated in detail in Figs. 4 to 9 inclusive. Referring more particularly'to said figures, the numerals I6, H,

18' and 19 designate a plurality oftubular membars which have their lower ends connected to openings in a cylindrical open-ended casing 89.

Each of said tubular members is fed from a suitable source with crushed mineral surfacing material of a different color. In the drawings two hoppers are shown mounted adjacent one another, but any desired number may be utilized. Journaled in the cylindrical casings is a shaft 8| having a pulley 82 on one end which is connected by an endless belt 83 with suitable driving mechanism.

Rigidly mounted in the cylindrical casing of each hopper, on the shaft 8|, in a hub 84 carrying spaced apart disk 85, and a plurality of radially extending partitions 86 between the disks to form a plurality of compartments. A tubular discharge portion 81, which communicates with an opening 88 in the lower portion of the casing 80, extends downwardly therefrom. A fan 89, driven by a motor 90, is positioned in the upper portion of the tubular member 81 to distribute the falling mineral material evenly therein.

Each of the feed pipes 16 and 19 is provided with a valve member 9| which is mounted on a rotatably mounted pin 92. One end of each pin has a weighted lever 93 secured thereto which is adapted to normally hold the valve 9| in closed position. Levers 94, 95, 96 and 97 are secured to the other end of each pin and said levers vary progressively in length and in the distance which they project laterally, the longest lever and the one projecting laterally the greatest distance 94 being in connection with the pipe 16 and the shortest and closest to the casing 91 being in connection with the pipe I9. Tripping pins 98, 99, I00 and IN project from an outer disk 85, there being one pin for each compartment between the disks. Said pins vary progressively in length and in'distance from the hub, the pin 98 being the longest and closest to the hub, and the pin IM being the shortest and farthest from the"hub. In view of the fact that there are eight compartments between each pair of disks and only four feed pipes, opposite compartments are provided with like tripping pins.

In operation of the automatic hoppers, the pipes 16, 11, 18 and '19 may be supplied with mineral material of different colors, as for example green, black, red'and yellow respectively. The valves at the lower ends of said pipes are normally held in closed position by the weighted levers 93. As the segmental drum, formed by the disks 85 and partitions 86, revolves, the tripping pin adjacent each compartment will operate to open the valve of only one particular feed pipe to admit crushed mineral of one particular color to said compartment. In Fig. 6, the tripping pin I08 is shown feed pipe 18. As the drum revolves further, the

pin I will pass the end of the lever 98 and the weighted lever 93 will return the valve to closed position, shutting off the supply of mineral to the particular compartment as shown in Fig. '7. Due to variance in lengths and positions of the levers 94 to 91 and tripping pins 98 to IOI, each pin will operate only the lever of a particular feed pipe. Thus, as the compartments reach the upper portion of their circle of travel during rotation of the segmental drum, each compartment will receive a different colored mineral from the adjacent compartment, and as the compartments reach the lower portion of their circle of travel the various colors of mineral will be discharged through the opening 88 into the tubular discharge portion 81 in differently colored strata. The strata will then be discharged by the grooved roller 43 either onto the web as shown in Fig. 4 or onto an intermediate receiving means as in Fig. 1, with the crushed mineral arranged on the receiving means in a relation corresponding to the arrangement of the strata in the hopper (see Fig. 11 for the surfaced web).

In Fig. 10, a modification of the invention is illustrated in which the crushed mineral is deposited upon a different form of belt I02 from that shown in Fig. 1. Said belt I02 is provided with transverse corrugations I03 thereon and is arranged to receive a measured supply of crushed mineral between said corrugations from a hopper I04 and to discharge said mineral onto a traveling web I05 below in the arrangement as received from the hopper. The hopper I04 is also of modifled construction, embodying vertical compartments I00 each containing crushedminerai of a different color. Grooved rollers I01, which relieve the belt I02 from the weight of all of the mineral,.may also be utilized. The belt I02 may also be constructed as shown at I02 in Fig. 12 with transverse ribs I03.

In Figs. 13 and 14a modified form of crushed mineral distributing device is illustrated which may be substituted for the hopper 40 of the principal form. In this construction a hopper I08, having a plurality of compartments I 09 and H0 is utilized, the said hopper being slidably mounted on a platform III over an opening II2 therein. The compartments I09 are fed with crushed mineral of differentcolors by fiexible tubes H3, and the compartments IIO are fed with mineral of other colors by flexible tubes II4. Brushes II5 may be provided adjacent the lower edges of the hopper to maintain the platform free from grit. The hopper is arranged to be reciprocated by a connecting rod I IS in connection with a driven wheel II'I. Grooved rollers II8 may also be utilized adjacent the platform opening I I2 to control the flow of mineral material therethrough, said rollers being driven by endless chains I I9.

In operation, when the wheel II! is rotated, the connecting rod IIB reciprocates the hopper I08 back and forth so that mineral material from the compartments I09 is first discharged through the opening II2 on a traveling web below, and then mineral material from the compartments IIO. By this arrangement almost any combination of colored mineral surfacing may be deposited on the coated web.

In Figs. 15 to 18 inclusive another modified form of crushed mineral distributing device is illustrated wherein the segmental drum is positioned horizontally instead of vertically as in the principal form. In this construction, a plurality of feed pipes I20 are arranged to discharge crushed mineral of different colors into openings in the upper portion of a cylindrical casing I2I. The said casing has a lower discharge openings I22 from which a tubular discharge member. I23 depends. A suitably driven grooved roller I24 is mounted adjacent the lower end of said discharge member, the said roller being adapted to deliver the crushed mineral to a receiving means below, which in the drawings is a coated web I25.

A shaft I25 journaled vertically through the casing I2I and driven through an endless chain connection I21 with a motor I20 has a segmental open-ended drum I29 mounted rigidly thereon. The said drum contains a plurality of compartments I30 which are arranged to receive crushed mineral from the feed pipes I20 and to discharge said material through the lower casing opening I22. In operation, mineral material of a different color is supplied to each feed pipe, and as the drum revolves, automatic valve mechanism (not shown) in connection with the feed pipes I20 will function to distribute crushed mineral of a different color to each compartment I30 of the segmental drum. The said valve mechanism may be of the general type shown in Figs. 4, 5, 6 and 'I and will operate in an identical manner so that each compartment is supplied by only one feed pipe.

The improved method of applying surfacing material to a fabric web consists broadly in depositing crushed mineral material of different colors' either directly onto a coated web of roofing material or onto an intermediate receiving means which in turn deposits the mineral on the web, the arrangement of the various colors on the web being in conformity to the arrangement of the crushed mineral material in the discharge hopper. Where an intermediate receiving means is utilized. the method in addition consists in utilizing a receiving means having depressions or the like therein to deliver a measured supply of differently colored grit in a predetermined arrangement to the web.

In utilizing the apparatus disclosed in Fig. 1 the saturated felt is fed beneath the hopper M which coats said felt with asphalt or the like. The coated felt is then directed over the tractor belt. The latter belt receives a supply of crushed slate or'other mineral from the hopper 40 and said slate is deposited between the upstanding portions of the tractor belt and also in the depressions 35 on top of the portions 35. The operation of the hopper which functions to discharge strata of differently colored slate has been hereinbefore described in detail. As the upper portion of the tractor belt travels beneath the coated web the asphalt on said web, which is in a plastic condition, will act to pick up the crushed slate from the tractor belt and said slate will therefore be deposited on the web in a definite color arrangement according to the arrangement of the strata in,the hopper 40. The web is then fed around the cooling drums 54 and 55 and in passing around the drum 54 the belt 56 will serve to more firmly embed the slate in the asphalt. It will be noted that the upstanding portions 35 of the tractor belt have formed dedepressed lines of demarcation upon the web. From the drum 55 the web passes beneath the cutting roller 58 which severs it into strips of a desired length. The lower portion of the tractor belt passes the brush 13 which serves to clean-off the portions 35 thereof. The belt also passes above the spray a parting substance onto the belt which serves to prevent the adhesion of surfacing material there- 'I0 and the latter sprays colors.

charged directly upon the web. A completed web which has been operated on in the manner I disclosed in Fig. 3 and above described will have the appearance shown in Fig. 11 wherein the lines on the drawings indicate sections of different In carrying out either of the. methods above described any of the various devices shown in Figs. 4, 13 and 15 for discharging crushed slate in a predetermined arrangement of colors may be utilized, as well as other variations of said de vices.
