To all whom it may concern.
Be it known that I, FREDERICK C. OVER- BURY, a citizen of the United States, residthe county of Bergen and State of New Jersey, have invented new and useful Improvements in Machines for signs. Ordinarily, however,
sent different shades or tints or Making Ornamental Roofing, following is a specification.
This invention has relation to prepared roofing elements and more particularly to those which are designed to be separately arranged on the roof in simulation of wooden or mineral shingles or tiles. 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 surfacethereof of crushed mineral such as slate, earthenware tile, granite and the like, and indeed such crushed minerals of different colors have been so placed on the elongated sheets of roofing material to constitute conventional predetermined dethe shingles and shingle strips havegjihad the surface thereof coated with crushed mineral of one color or another so that the entire area of such elements, when placed on the roof, presents an unvarying color, shade or tint. While the 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 certain aesthetic and ornamental efi'ects. That is, notwithstanding that mineral coated roofing elements have attained a certain vogueand 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 artistic tastes. Natural building materials, such wooden shingles, when exposed to the weather, even when stained, are so acted upon by the wind and weather, as to precolors -in of which the coated on different unpredetermined areas, just as seam-faced granite because of its natural formation presents to the eye beautiful varled color tones I have discovered, as pointed out in my application, Serial No; 152,492, filed March 6, 19 1 7, of which this is a division, that it is posslble to destroy the monotonous efiectproduced on the eye by the mineral coated elements when laid on the roof, by employmg crushed minerals of different colors and shades, and soapplying the same to the-elements in the process of manufacture, as to provide variable areas having one color and yariable areas of other color with intervenmg areas where the colors blend or shade from one to the other, these various areas constituting no predetermined or related deslgns but occuring very much as they occur In seam-faced granite or other natural materials, This result may be accomplished by the employment, for example, of green and red crushed slates, which are delivered to the sheet of adhesive-coated fabric in such way that ortions or areas onthe sheet are y with green slate, other portions or areas with red slate, and the intervening portions or areas with a mixture of the two differently-colored materials.
Upon the accompanying drawings, I have illustrated conventionally a form of apparatus embodying the present invention which may be employed in manufacturing roofing elements such as described.
Referring to said drawings,-
Figure 1 represents conventionally instrumentalities embodying one form of my improvements and which may be employed for the manufacture of the shingle strips.
Figures 2 and 3 represent the instrumentality for applying the difi'erently colored crushed mineral materials.
Figure 4 represents an attempt to illustrate the sheet of material and to show the areas of different colors thereon.
Figure 5 represents a longitudinal section through a valve by which the crushed mineral is fed to the machine shown in Figures 2 and 3.
Figures dm 9 inclusive represent trans verse sections through the multiple Valve.
Figure represents a cross section showing the valve closed.
Figure 11 illustrates the end of the valve mechanism.
Figures 1:2 and 13 illustrate another form of valve mechanism which may be used.
it will of course be understood that the drawings are more or less diagrammatic and show the several instrumentalities more 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 inipreguatiug a sheet of fibrous material such as felt or the like with the usual waterproofing composition of a hydrocarbon or bituminous nature. This is indicated at and it may comprise a suitably heated tank orvat for containing said compound. through which the sheet (1 is drawn from a roll I). Squeeze rolls 21 remove the surplus 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 coating of 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 of the sheet. lietween the two inst-rumentalities A and 1% may be arranged ad ditional coolingrolls if desired. .\s shown. the apparatus B has the cooling rolls ELL-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 description of this machine is given hereinafter.
The fourth instrumentality D is the machine which cuts the sheet into the rooting elements. Any suitable machine may be used for this purpose for either longitudinally slitting the sheet and transversely severing it at inter ads 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 spaced tabs or projections (Z. In lieu of 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 'vening strata of green.
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 have shown it as provided with cooling rolls or cylinders and also with the rolls 3U, 31, to the former of which the coated fabric passes from the machine B, while the coating is still in an adhesive condition- Arranged in operative proximity to the roll 30 is a trough 32 which extends from end to end of the roll and to which the differently colored surfacing minerals are delivered, and from which it is fed to the coated fabric. This trough has the feeding roll 132. This material adheres to the coated sheet and is partially embedded therein as the sheet passes between rolls 3t) and 31. the surplus mineral material falling back to the trough as the sheet passes over roll 31 to the cooling rolls or drums 29. surfacing minerals are contained in separate compartments or receptacles and are delivered in batches to the trough. A hopper 33 is divided longitudinally by a partition 31 into two compartments 35, 36. of which the former may contain for example red crushed slate. and the other green crushed slate. These compartments converge at their lower ends to a valve casing 37 in which I have shown a multiple valve 38. This valve has four passageways for the mine 'al material therethrough. two as at 40 and two as at 41, thoseat it) and 11 alternating.
arranged that. when the valve passages 10 communicate .withhcoinpartment 36, those at 41 communicate with compartment 35 and vice versa. Thus a-t the same time two. streams of red slateare being delivered to certain portions of the trough and two streams of green slate to other portions thereof. On rockim the valve to its other operative positions, t e streams of red slate are cut off and are followed by streams of green slate, and the streams of green slate are cut off and are followed by streams of red slate. Thus there are delivered to the troughs different batches of colored mineral. and there are strata of red in each batch with inter- 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 trough, unconventional patches of green and red slate will be applied respectively to different portions or areas of the sheet, between which areas will be areas in which the two colors willbe mixed or blended Without any lines of demarcation. Thus the sheet will present a more or less mottled appearance as indicated conventionally in Figure 4. The valve may be operated by hand, but, preferably, it may be operated automatically. To this end, I may affix to the valve a weighted arm 43 connected by a rod44 to a lever The differently colored These are so 45 oscillated by a cam 46. The latter may be driven by a belt 47 and pulleys 48, 49, the latter being operated by roll 30. The rod 44 is shown as detachably hung on a pivot 50 on weighted 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 Figure '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 Figures 12 and 13 I have illustrated the two large hoppers or receptacles 60, 61, from which lead the spouts 62, 63, for the purpose of delivering the differently colored grit to the hopper 32. These spouts are controlled by sliding valves or gates 64, 65 which may be operated manually or automatically as desired. Other specific forms of valve mechanism may be employed if desired.
What I claim is:
1. Apparatus for making variegated roofing, comprising means for saturating a sheet of fibrous material, means for applying a layer of plastic asphalt to the face thereof, a trough for showering crushed slate on the plastic, coating, separate receptacles for masses of differently colored slate, and controlled means for controlling the supply of slate from said sources to said trough.
2. Apparatus for supplying crushed slate to a sheet of coated roofing, comprising separate receptacles for containing masses of slate of different colors respectively, a trough for showering the sheet with such slate, and controlled valves for causing the simultaneous delivery to different portions of said trough of slate from certain of said receptacles .to said trough.
3. Apparatus for supplying crushed slate to a sheet of coated roofing, comprising separate receptacles for containing masses of slate of different colors respectively, a trough for showering the sheet with such slate, and mechanism for delivering slate from certain of said receptacles alternately to said trough.
4. Apparatus for supplying crushed slate to a sheet of coated roofing, comprising separate receptacles for containing masses of slate of different colors respectively, arranged in two series, a trough for showering the sheet with such slate, and controlled means for delivering slate to said trough from each of said receptacles intermittently and from certain of them simultaneously.
In testimony whereof I have afiixed my signature. FREDERICK C. OVERBURY.
