STRIP GLE 3 v Joseph A. Murray, Bethesda, Md. Application swaths; 14, mile; gain No.4581269 1 Claim. (01.10857) =--This,;invention relates to strip shingles and vparticularly .to strip shingles which, when laid,

expose tothe weather a plurality of shingle simulating tabs. Theinvention relates to thetype of strip shingle which has a continuous lower edge and in which the tab is itself also a simulation bined with materials ordinarily wasted. A particular object of the invention is to make pos- Zfnmargin of the felt beforeit enters the rolls so that the rolls will fold it down and flatten it against the upper. face of the felt. The strip 2 with its folded over edge l4 now passes tov a coat- "ing mechanism-which operates to coat both faces of the strip with asphalt. The coating mechanism shown :comprisesia lower rollerv i6 dipping into asphalt in a tank 18 and an upper roller-20 which is supplied-with asphalt from an upper sible the use of slate coated roofing waste, either in whole or in part, for producing the exposed faces of the tab simulating portions of the strip shingles. v- I Another object of the invention is to produce at a relatively lowv cost of manufactur strip' shingles in which most desirable color effects can be obtained. Other objects and important featuresof the invention will appear fromthefollowing description,and claims when .considered in connection with the accompanying drawings in which--- i Figure 1 shows a plurality of strip shingles of the present invention and the manner of laying them upon a roof; I Figure 2 shows. a strip single embodying the present invention;

Figure 3 shows a simple method of manufacturing these shingle strips and also simple apparatus which may be utilized in practising the method.

similar material is preferably slitted to form two i 16" strips, each of which is preferably again rolled for convenience in handling.

As shown in Figure 3, the 16" strip 2 as it comes from the roll 4, mounted on the spindle 6, is passed between two draw rolls 8 and I0. Before the strip 2 enters the draw rolls it strikes a turning flange I! which is shaped to turn over a tank 22 having a feed spout 24 controlled bya valve 26. Theasphaltpusedin coating the strip 2 may be, either hot. asphalt or cold emulsified asphalt. Hotasphalt'is preferably used.

.While the asphalt coatingqis'still tacky the sheet is passed over av working table 28 where one or more. workers place pieces of slate-surfaced, asphalt saturated and'coated felt in position tosform the tab-simulating portions of the stripshingle. These pieces, as, above pointed out, may be cut from roofing waste and each may be of a different color, if so desired, to produce desired color effects on the roofing. If sufficient waste does not accumulate to meet the demands for, thesetab simulating rectangular pieces it is still an economical procedure to cut them from new materialsince, only square feet of such material will be used in providing a square of stripshingles embodying this invention as compared with 250 square feet of such material required to ,make a-square of ordinary strip shingles.- V H g'Ifhe pieces .employedto make the tab-simulatingportions of.theshingle strip for a strip shingle 36, f.-1ong:and:1 4" from top to bottom may-:be of any suitable dimensions depending upon the desired exposure and head lap. For a 6" exposure and a head lap of 4", suitable dimensions of the pieces might be 5" x 8" and 5" x 7", using both on the same strip to give variety. 7

These pieces of slate-coated material are preferably placed 1" apart along the strip and up from the lower edge of the strip, a 2" margin of coated felt being left at the left hand end of the strip and a 1" margin at the right hand end of the strip. If two 5" x8 pieces and two.

5"x7" pieces are used, this will give for the length of the strip 2" plus 8" plus 1" plus '7" plus l" plus 8" plus 1" plus '7" plus 1" equals 36"..

The tile or tab pieces 30 having thus been placed in position on the strip, the strip is then passed through pinching rolls 32 and 34 which press the tabor tile pieces 30 into the asphalt to insure proper adhesion, after which the surface is dusted with talc or other suitable material for preventing sticking in piling. The duster is shown at 36. A shear 38 acts to cut the strips to the proper lengths.

As shown in Figure 1, if a strip be constructed in this manner with the tab or tile 30 at the right hand end one inch from the side edge of the strip, the strip may then be laid with a 2" side lap and a 4" head lap to give complete double coverage throughout the roof.;; The 2", side lap leaves an inch of the base surface exposed between the tile near the right hand edge of one strip and the left hand tile of the next strip in order to provide between these two tiles the deep contrasting shadow line essential to produce a simulation of individual shingles. a

In laying a roof of strip shingles of the con struction hereinabove described,- the strips are laid in courses across the roof. The lower edges of the strips may be drawn back a sufllcient distance I the lower edges of the tiles 30 and the lower edge of the strip. From the description of the process of making the strip it will .beseen that the strip has already a substantial butt thickness so that with this shadow effect produced by the 12'" margin or further emphasized. by drawing the strip back slightly from-the upper edges of the tiles 30 of the strip below there will beproduced a marked thick butt effect as shownin Figure 1. The side lap, that is, 2" at the left band edge of each strip is tucked under the strip to the leit of it and can be cemented thereto if desired-further to prevent any tendency of the strip to blow up, The fact that the area around the overlap is black facin tates this cementing since slight smearing of the cement outside the overlap does notm'ake a visible stain. Shingles or strips of this type are customarily nailed with two to three large head roofingnailsso located the black area above the tiles thatthe next strip'above overlies the nails for at least 2". 1

Some of the advantages or the" novelstrip con-' struction of the present invention have been pointed out hereinabove. Other advantages to which attention has not been particularly directed are the fact that the strip is quite markedly ta pared, with a heavy butt and a lighter flexible under body, so that it tends to lie flatter in the roof and the successive strips conform to each other better than other types of strip shingles on the market. Furthermore the tiibS, 01' $1163 30 give each tier a substantially continuous body thus preventing curling and blowing up. In addition, the deep shadow lines produce a massive appearance of the shingle tabs on the roof. With strips of the dimensions hereinabove described, as few as '70 strips are required for a roofing square.

Strips of this general construction can also be used as siding material to simulate brick walls. The relative thinness and flexibility of the under body of this strip, which permits the strip to conform more readily to the course below, especially suits this strip for use in simulating brick siding, since the rigidity of the underlying portions of other imitation brick sidings on the market often tends to force the butts to stand away from the walls, thus completely destroying the brick wall eifect.

Although we have hereinabove referred to tilelike or rectangular pieces of'slate-surfaced, asphalt-coated and impregnated felt as constituting suitable material for use in making the imitation tabs and the expression felt has been used in the" claim to define this material, it will be understood that the invention contemplates also the employment of any suitable substitutes for the asphalt-saturated and coated and slate-surfaced felt which may be available, particularly in the form of waste or scrap material.

What I claim as new is: I

A strip shingle comprising a strip of relatively light unsurfaced waterproof material having a marginaledge portion thereof folded over to in: crease the butt thickness of the strip,-a coating of asphalt covering the strip, and rectangular pieces of previously slate surfaced; asphalt coated and impregnated felt of an up and down aimed: sion approximating the strip shingle exposure di-' mension, said pieces being embedded in the asphalt coating in, spaced relation to each other along the butt edge of said strip to simulate tabs and to give an increased thick butt effect, said asphalt coating serving also tosecure said folded.

over margin in its folded condition and at the same time to increase further the thick butt effect and the rectangular piece at one end or the row of pieces being spaced from the side edge ot the strip a distance equal to a tab spacing and the rectangular piece at the other end being spaced from the side edge to provide both fora sub stantial side lap and also for exposure of a pertio'n ofvthe upper strip base between said end rectangular pieces.
