ROOFING.

Application filed January 20, 1925.

This-invention relates to roofing, more particularly of the wide spaced type where individual units are laid in overlapping courses, the adjacent units of each course being spaced a substantial distance apart, the spaces being bridged b the units of the next superposed course. Vi hen rectangular shingles are laid up in this manner it requires considerable skill and experience to correctly place the units to produce the desired effect, there being nothing to indie-ate the proper spacing or the places where securing nails should be driven.

According to this invention the units are i so formed that the correct spacing and positioning of the several units is readily accomplished, the improper positioning of the fastening nails avoided and whereby either one of two patterns, as herein shown a rectangular and a hexagonal pattern, is produced in the completed roof as may be desired. This choice of patterns is efiected by cutting opposite ends of the units to different contours, which presents also the further advantage that by cutting all the units facing in the same direction from the web of sheet material, all the units are positioned in the same direction of the sheet Whatever pattern is selected so that as laid the units present a uniform color appearance, it being Well known that where units are laid in different positions relative to the length of the web of roofing material as formed on the roofing machine they resent different color efiects when viewed rom a distance.

For a more complete understanding of this invention reference may be had to the accompanying drawings in which Figure 1 shows in plan a single roofing unit shaped according to this invention.

Figure 2 illustrates a portion of a roof made u of these units, the tapered ends thereof being downwardly presented and bein exposed to the weather.

igure 3 is an edge View of the same.

Figure 4 is a view similar to Figure 2, except that the units are positioned the other end up so as to present rectangular tabs to the weather.

Referring to these figures, it will be seen 50 that the shingle comprises a piece of sheet material having one end formed substantially rectangular, as at 10, and the other end formed tapering as at 11. The rectangular portion is wider throughout than the widest 5 portion of the tapered portion, the two being Serial No. 3,578.

defined from each other by means of inwardly extending shoulders 12 on each side, each of the shoulders being of materially less than one half of the width of the end of the tapered port-iont The side edges 13 ot' the tapered portion are widest apart at the inner ends of the shoulder edges 12 and converge toward each other toward the edge 14. The rectangular portion is of the full width of the shingle unit between the edges 15.

Units of this description may be laid either end up. As shown in Figure 2 they are laid with the narrow portions projecting downwardly, the units of each course being spaced apart a distance such that the lower edge 14 of a superposed course bridges the space between and overlies the shoulders 12 of ad.- jacent shingles of the course beneath. Thus the lower ends of the edges 13 of the superposed shingle'nieets the upper ends of the.

adjacent edges 13 of the pair of underlying shingles so to define withthe lower edges 14 of the several shingle units a hexagonal pattern such as is shown in Figure 2. As the shoulders at 12 are overlaid by units of a subsequent course they serve to indicate proper positions for securing nails to be driven since a nail driven just above each shoulder will be covered by an element of the overlying course and yet will be as far down toward the butt end of the shingle as possible without causing it to be exposed to the weather.

When each shingle is laid, therefore, it may be secured in position by nails positioned at the ints 20, as shown in Figure 2, passing through the upper shingle and the shingle unit overlaid thereby. The sh ulders 12 also form guiding edges to determ ne the proper position for the lower edge}; of the superposed unit so that after a sin le row of shin- 9 gles has been laid properly paced, the position of all the superposed shingles is clearly indicated as it also the position for driving nails therethrough. Shingles thus made are therefore very easily laid in wide spaced relation, there being no particular skill or experience required to insure their proper positioning on the roof, the shingles being spaced the length of the edge 14 diminished by the combined length of the shoulders 12 whichever ends of the shingles are expqsed to the weather.

Similarly if it is desired to present the rectangular butts in the manner of the well known widespace shingle, this may be done face an area ten feet square.

as shown in Figure 4:, the shoulders 12 of each shingle conforming to the upper edges 14 of the units overlaid thereby, the units being spaced so that the ends of the edges 14 coinside with the inner edges of the shoulders 12 of the superposed units. The securing nails may then be driven below the shoulders 12, as at 21, care being taken, however, to place these nails sulliciently high so that they will be covered by the units of the next overlying course.

These shingles may, if desired, be cut seventeen inches long, fourteen inches in great est width, ten inches in least width, and with the shoulders 12 each one inch in length, and positioned five inches from the narrow end. One hundred and thirty-one such shingles laid five inches to the weather, and represent-- ing approximately two hundred and seventeen square feet of roofing material will then be required for each square, that is, to sur- There are at least two layers of roofing material within any considerable distance of exposed edges so that weather tightness is amply assured and with the use of a total area of material appiroximating twice that of the roof covere Having thus disclosed an embodiment of this invention, it is evident that, many changes and modifications might be made therein without departing from its spirit or scope as defined by the appended claims.

I claim:

1. A roof comprising overlapping coursesof the narrow portion, adjacent elements of the same course being spaced apart a distance equal to the width of the end of said relatively narrow portion diminished by the combined lengths of said shoulders.

2. A roof comprising overlapping courses of roofing elements, each of said elements having a relatively narrow portion and a relatively wide portion defined from said narrow portion by laterally extending shoulders, said shoulders each being substantially shorter than half the length of the end edge of the narrow portion, adjacent elements of each course being spaced apart and having their narrow end edges bridging the space between adjacent elements of the next underlying course and registering with adjacent shoulders thereof, and fastening elements passed through said elements adjacent to said shoulders.

3. A roof comprising overlapping courses of roofing elements, each of said elements being flat throughout its entire extent and having a lower relatively narrow portion and a downwardly tapered portion and an upper relatively wide rectangular portion de ned from said lower portion by laterally extending shoulders, said shoulders each being substantially shorter than half the length of the end edge of the narrow portion, adjacent elements of the same course being spaced apart a distance equal to the width of the lower end of said tapered portion diminished by the sum of the lengths of said shoulders, and each element. having its lower edge bridging the spacebetween adjacent elements of the next underlying course and registering with. the adjacent shoulders thereof.

In testimony whereof I have aflixed my signature. HENRY R. FRENCH.
