' 20 Claims. (01.91-43) The invention relates primarily to prepared roofing, but many of its novel features are applicable'to other things. v

Among its manifold objects are to produce prepared roofing surfaced with grit ina plurality of colors and having qualities superior to anything heretofore obtainable, to eliminate duplication the surface appearance of shingles or shingle strips, and, hence; the repetition of color designs or forms on the roof, to permit a design or scheme illustrated on paper to be readily produced in colored grit on roofing, and to provide a unit for applying colored grit that can be quickly inserted and" removed from conventional roofmg, machines.

Further objects and advantages of the invention will be revealed as the disclosure proceeds and the description is read in connection with the accompanying drawings illustrating a selected embodiment of the invention, and in which Fig. l is a diagrammatic view of a roofing ma-v chine including a unit made according to thisinvention for applying colored grit;

Fig. 10 is a plan view in which it is attempted to illustrate one pattern or design thatmay be produced in colored grit by proceeding according to this invention; and V Fig. 11 is a perspective view of a package of shingles.

Butthe specific illustration and the correspondingly specific description are used solely for the purpose of disclosure, for it is realized that the invention may be embodied in a great variety of machines, not only for making'roofing, but other things composed of materials of different colors laid, or arranged in a pattern or design.

It is common practice to cover composition 66 roofing with colored granules and to employ (up ferent colors in the form of patterns oi? one type or another.

Itv has also been proposed to blend the colors at the edges of the patterns in one way orfanother but the devices for applying the colored grit or granules to the roofing, as heretofore used are so constructed that they are required toloperate at a predetermined speed in order to secure the result-s intended. Furthermore, the blending of T the different colored portions of the roofing has caused more or less trouble. The present invention seeks to avoid these difiiculties'by the provision of a new and improved method of, and apparatus for, applying colored grit or granules to the roofing material. -It has been learned by -experiment that if the differently colored granwhich has been saturated with an asphaltic waterproof composition and supported on a looper 11,

see Fig. 1, preparatory to passing through a coater 12, equipped with calender rolls 13,- and a scraper 14. 9

In conventional roofing machines there is also a grit or granule feeding device 15 of some form for scattering grit or granules on the upper surface of the sheet 10, just after it leaves the coater and just before itpasses around a roll 16 which serves to press the grit into the coating. Excess grit is delivered into a hopper 1'7 equipped with a conveyor 18'for disposing of it according to conditions. The sheetordinarily is reversed by a roller 16, and a cooperating similar roller 19 and talc, or the like, is applied to the opposite side by some device' 20, that is pressed into the coating as the sheet passes over the roller 19. Thereafter the sheet is usually passed about a set of small rolls, generally indicated at 21, before going to the cooling rolls, generally indicated at 22.

Machines including devices of the general character described are in common use for the manuwheels whereby it is readily removed into and out of". place.

A'plurality ofgravity conveyors 26 (Figs. 1, 6 and 7) bring grit or granules of different colors from storage bins (not shown) to extended delivery hoppers 27, which have a common bottom plate 28 provided with perforations 29 for discharging grit therefrom into a plurality of supply hoppers 30 formed by inserting partitions 31 in a large hopper 32 of rectangular form in plan; and having sloping sides 33. The delivery to the hopper 30. is made selective by providing plugs 34 for closing any of the holes 29 -to thereby prevent the delivery of grit or granules of a color' to any particular hopper 30.

The schematic arrangement is perhaps best illustrated in Fig. 3, which shows the hoppers 30 in plan and the delivery hoppers 27 in section, just above the hoppers 30, and'it will be'clear that by selecting perforations 29 agreat variety of assortments of colored grit or granules may be provided.

Thehoppers 30 are provided with a common bottom 35, having a large number of perforations 36 through which the grit may escape from the hoppers into measuring devices 3'7, which successively assemble measured charges or charges of predetermined bulk of grit of different colors arranged in accord with the color design or eflect to be produced, and from which those charges are discharged onto the sheet 10.

[faces 54.

The measuring devices (Figs. 4 and 5) consist of telescoping sleeves 38 and 39 fixed to perforated plates 40 and 41, respectively.

' The plate 41 rests upon a plate 42, having perforations 43 arranged the same as the perforations 36 in the commonbottom of the hoppers,

but out of line therewith.

The measuring devices are first brought into register with the perforations 36, substantially as shown in Fig. '4, and thus receive a charge of colored grit or granules by gravity. Afterward they are shifted out of register with the perforations 36 to sever the flow from above and into register with perforations 43, substantially as indicated in Fig. 5, to permit the discharge by gravity of their contents.

Incidentally the measuring devices in the machine here illustrated are arranged in two groups, one of which is in register with perforations 36, and therefore is being charged, as illustrated in Fig. 4, while the other is in register with perfora tions 43 and is being discharged, as indicated in Fig. 5.

The plates and 41, with their attached telescoping sleeves, are shifted by a cam 44 (Figs. 3 and 6), cooperating with anti-friction rollers 45,

carried by brackets 46 made fast to the plates 40 and 41 by bolts 47, and equipped with guides 48 running between sets of anti-friction rollers 49, journaled in flanges 50 on the sheet or apron 51.

The measuring device may be regarded as a member provided with chambers each having an inlet port and an outlet port, which ports are alternately opened and closed, i. e., when the inlet ports are open the outlet'ports are closed,

ing devices to the right, where they remain until the same surface 54 strikes the leftroller 45,

when they are brought back to the position shown in Fig. 6. It will, therefore, be obvious that the measuring devices will shift somewhat quickly and between shifts are allowed'to remain stationary for an interval sufficient to permit charging and discharging.

The capacities of the measuring device may be adjusted by adjusting the relative position of the plates 40 and 41. To this end the plate 40 is supported on anti-friction rollers 45 (Fig. B), and the plate 41 is supported on similar rollers 56 carried by an adjustable frame including bars 57, 58, 59 and. 60, which may be'adjustedby the bolts 61 and held in adjustment by the bolts 62.

This adjustment is provided to permit such accurate measuring or metering of the total amount of grit delivered to the. sheet per unit of travel that there is only suilicient excess to insure that no blank places will occur.

The sheet 10 passes through this part of the machine at an appreciable distance below the plate 42 and the measured charges of 'grlt or granules descending from the measuring devices are consequently spread to a considerable extent in passing through the air. It is, however, preferable to interpose between the measuring devices and the sheet a screen 63, which, in this instance, is given a somewhat rapid oscillating motion'by an eccentric 64 (Fig. 6), equipped with a connecting rod 65 pivoted to the frame 66 in which the screen 63 is mounted. The frame 66 is supportedby links ,67 pivoted to it and to the frame The eccentric 64 is driven from the shaft 68, carrying the cam 44, in a ratio of eight to one, from which it will be obvious that and the delivery hoppers 2'1, to the supply hop-- pers 30.

The measuring. devices will successively withdraw from the supply hoppers 30 measured charges of the selected colors arranged roughly in accord with'the design to be produced and discharge them onto the sheet 10, which may be continuously driven, as iscustomary, or intermittently driven,'if desired. The pattern to be produced is determined, in the first instance, by the shape, capacity and arrangement of the measuring devices, for they, in

effect, assemble the required quantities of differently colored grit or granulesand discharge them as a salvo of charges against the sheet. In, other words, these measuring devices isolate measured charges of the grit from the mass and. drop the charges onto the sheet, thereby projecting the design as a composite of the several patterns produced by the scattered charges. This effect, however, is modified to some extent by the action of the screen 63, and by selecting the movement given that screen it can be modified still more.

By making the area of the sheet covered by each salvo of charges of such a dimension lengthwise to the sheet that it is neither a multiple nor a divisor of the corresponding dimension of a.

that can be made to vary the effects produced are so great that no attempt will be made to show or describe them. The forms shown in the drawings, however, are sufllcient to illustrate the fundamental features of the invention, and those skilled in the art will be'able to make iorms of mechanism for pertormingthe steps of the process as required to produce the effects desired.

The machine'here illustrated will produce a design or pattern in which the areas covered by particular colors are very irregular in form andv size, and in which the marginal portions are blended with the colors or adjoining areas. It will be obvious that the shape and size of the areas may be varied at will by changing the shape or arrangement of the measured charges, the manner of projecting them, and the .motion given the screen. a

In Fig. 11 there is illustrated at a bundle of shingles which, in accordance with this invention, are each of a diiierent design irom,all the others, and hence the roofer needgive no attention to'the order in which they are laid, for it is impossible that any duplication of designs on individual shingles or patterns on the root can occur.
