EROCESS OF PRODUCING ORNAMENTAL ROOFING.

Application filed March 6,

To all whom it may concern:

Be it known that I, FREDERICK C. Oven- BURY, a citizen of the United States, residing at Hillsdale, in the county of Bergen andState of New Jersey, have invented new and useful Improvements in Processes of Producing Ornamental Roofing, of which the following is a specification.

' This invention has relation to prepared roofing elements and more particularly to those which are designed to be separately ar ranged on-the roof in simulation of wooden Usually such elements are in the form of what are termed shingles or shingle strips, and they are more or less flexible, being cut from sheets of prepared weatherproof material. In order that such elements may be used on dwellings and high grade structures, they have heretofore been ornamented, and incidentally rendered more fire-proof, by the application to the surface thereof of crushed mineral such as slate, earthenwear tile, granite and the like, and 1ndeed such crushed minerals of differ cut-colors have been so placed on the elongated sheets of roofing material to constitute conventional predetermined designs. Ordinarily, however, the shingles and shingle strips have had the surface thereof coated with crushed mineral of one color or another so thatthe entire area of such elements, when placed on the roof, presents an unvarying color, shade or tint. lVhilethe provision of such shingles or shingle strips have greatly enlarged the scope of their usefulness, nevertheless they have failed to meet the demands of those who are insistent upon and ornamental effects. That is, notwithstanding that mineral coated roofing elements have attained a certain vogue and have been used in large quantities on the roofs of dwellings, yet when laid they present a flat and unvarying and hence uninteresting monotonous appearance which is offensive to those who have artistictastes.

Natural building materials, such as wooden shingles, when exposed to the weather, even when stained, are so acted upon by the wind and weather, as to present different shades or-tints or colors in differentv unpredetermined areas, just as seam-faced granite because of its natural formation presents to the eye beautiful varied color tones.

I have discovered that it is possible to Specification of Letters Patent.

destroy the monotonous effect produced on the'eye by the mineral coated elements when laid on the roof, by employing crushed minerals of different colors and shades, and so applying the same to the elements in the process of manufacture, as to provide variable areas having one color and variable areas of other color with intervening areas where the colors blend or shade from one to the other, these various areas constituting no predetermined or related designs but occurring very muchas they occur in seamfaced granite or other natural materials. This resultmay be accomplished by the employment, for example, of een and red crushed slates, which are delivered to the sheet of adhesive-coated fabric in such way I that portions or areas on the sheet are coated only with red slate, other. portions or areas with red slate, and the intervening portions or areas with a mixture of the two difl'erently-colored materials.-

Upon the accompanying drawings, I have illustrated conventionally a formfilof apparatus which may be employed in manufac' turing roofing elements embodying the 1n vention and for practising the invention.

. Referring to said drawings,-

Figure 1 represents conventionally instrumentalities embodying one form of my improvements and which may be employed for the manufacture of my improved shingle strips.

Figs. 2 and 3 represent the instrumentality for applying the differently colored crushed mineral materials. I

Fig. 4 represents an attempt to illustrate the sheet of material and to show the areas of different colors thereon.

Fig. 5 represents a longitudinal section through a valve by which the crushed mineral is fed to the machine shown in Figs. 2 and 3.

, Figs. 6 to 9 inclusive represent transverse sections through the multiple valve.

Fig. 10 represents a cross section showing the valve closed.

Fig. 11 illustrates the end of the valve mechanism.

Figs. 12 to 13 illustrate another form of valve mechanism which may be used.

It will of course be understood that the thro ugh or less conventionally, and that the latter may be of any approved construction or design. The instrumentality first in order of operation is an apparatus for saturating or impregnating a sheet of fibrous material such asv felt or the like with the usual waterproofing composition of a. hydrocarbon 'or bituminous nature. This is indicated at A, and it may comprise a suitably heated tank or vat 20 for containing said compound, which the sheet a is drawn from a roll compound from the now saturated sheet prior to its passage to the next instrumentality.

The second apparatus is indicated at B, and it is an apparatus for applying to one face of the saturated sheet a coatingof pitch or asphalt having the desired consistency and melting point at ordinary temperatures. This material is applied in a molten or plastic adhesive condition and extends from edge to edge ofthe sheet. Between the two 'i'nstrumentalities A and B may be arranged additional cooling rolls if desired- As shown the apparatus B has the cooling rolls 22, and the rolls 23, 24, in connection with the latter of which there is the receptacle 25 for the molten pitch or asphalt, which is spread on the surface of the impregnated sheet.

The third instrumentality is indicated at C and applies the different mineral materials to the sheet while the bituminous coating thereon is still adhesive. The particular de-.

scription of this machine is given hereinafter.

The fourth instrumentality Dis the ma-' chine which cuts the sheet into the roofing elements. {Any suitable machine may be used for th1s purpose for either longitudinally slitting the sheet and transversely severing it at intervals to form shingles of oblong or other shapes, or else cutting it into shingle strips such as shown in Letters Patent No. 1,150,298, dated August 17, 1915. For example, the machine shown is similar to that shown and'described in my Letters Patent'No. 1,182,417, dated May 9, 1916, and includes the feeding rolls 26, the cutting rolls 27, and the chopping knife 28 for forming the sheet a,'the shingle strip 0 having the spacedtabs or projections d. In lieuof the machine thus conventionally illustrated, I may employ any other equivalent machine for producing the detached roofing elements.

Between the third and fourth instrumentalities may be arranged a festooning and cooling mechanism of any suitable sort, although I have not thought it necessary to illustrate the mechanism as it is well known.

Returning now to the surfacing machine (i, I have shown it as provided with cooling fabric passes from the machine B, while the Squeeze rolls 21 remove the surplus coating is still in an adhesive "condition. Arranged in operative: proximity. to the roll 30 is atrough 32 which extends from end to end of the roll and to which-the differently 'colored' surfacing minerals are delivered,

mineral material falling back to the trough as the sheet passes over roll 31 to the cooling rolls or drums 29. The difierently coloredsurfacing minerals are contained in separate 1 compartments or receptacles and are delivered in batches to the trough. They may be manually shoveled into'the trough in such way as to secure the desired result, but I have shown conventionally an automatic mechanism for feeding them to the trough, which I shall now describe. A hopper 33 is divided longitudinally by a partition 34 into two compartments 35, 36, of which the former may contain for example red crushed slate, and the other green crushed slate. These compartments conver e at their lower .ends to a valve casing 37 inwhich I have shown a multiple valve 38. This valvehas four passageways for the mineral material therethrough, two as at 40' and two as at 41, those at 4Qand '41 alternating. These are so arranged that, when the valve passages 40 communicate with compartment 36, those at 41 communicate with compartment 35'- and vice versa. Thus at the same time two streams of red slate are being delivered to troughs difi'erent batches of colored-mineral,

or portions and there are strata of red in each batch with intervening strata of green. Where these batches meet, the materials mingle or mix as will be well understood, as there '.is nothing to separate them. Hence, as the coated sheet passes the trouh, unconventional patches of green an areas will be areas in. which the two colors red slate will be applied respectively to difiere'nt portions or areas of the sheet, between which will be mixed or, blended without anyv lines of demarcation. Thus the sheet will :present a more or less mottled appearance as indicated conventionally in Fig. 4. 'The valve may be operatedby hand, but,'if desired it mzziy be operated automatically.

en I may afiix to the valve a weighted arm. 43 connected by a rod 44 to a lever 45 oscillated by a cam-46. The latter may be driven l 1,3 -M11147 and ulleys 48, 49, the latter bei .To t is neeaava :gTIOWII as detachably hung on a pivot-50 on eighted arm 43, but, by lifting the latch 51, the rod 44 may be disconnected therefrom, allowing the arm 43 to drop to move the valve in position to cut off both streams of mineral to the trough, as indicated in'Fig. 10. When the rod is disconnected, the valve may be operated manually. The valve mechanism, which I have illustrated and described, may be replaced by any mechanical equivalent therefor, which will readily suggest itself. For example, in Figs. 12 to 13 I have illustrated the two' large hoppers or receptacles 60, 61, from which lead the s outs 62, 63, for the purpose of delivering the differently colored wit to the hopper 32. These spouts are contro led by sliding valves or ates 64, 65, whichmay be operated manual y or automatically as desired.v Other forms of valve mechanism may be employed,

r, as previously stated, the different batches of difi'erently colored grit may be shoveled bv hand into the hopper 32.

Having thus explained the nature of my said invention in roofing elements and de scribed a process and one set of instrumentalities for producing the same, what I claim 1s: v

The herein described process of making mineral surfaced ornamental roofing elements, which consists in passing a sheet of adhesive-coated fibrous material lunder a mass of crushed mineral material, consisting of alternatin strata of differently colored material, each stratum consisting of alternatingbodies of differently colored material, and causing said differently, colored mineral materials to adhere in irregular areas of different colors with intervening areas having a mixture of colors thereon, and then partially embedding said mineral materials by pressure into the adhesive coating of said sheet.

In testimony whereof I have aflixed my signature.

FREDERICK O. OVERBURY.
