Application led March 29, 1920. Serial No. 369,801.
To all whom zt may concern:
Be it known that I, NORMAN P. HARSH- BERGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shingles, of which the following is a specification.l
This invention relates to Shingles for covering roofs, and has for its object the production of suitable shingles for the purpose, the Shingles being so formed that the exposed parts thereof may be locked by the adjacent shingles in such a manner that,J it iS impossible. for any portion of the exposed parts to be turned up by the wind or by warping or in any other manner. Another object of the invention is to provide shingles of such a sha-pe that they may be cut from Strips of material in such a manner that there is substantially no waste whatever in forming the shingles. Another object of the invention is to provide shingles of such shape, that the appearance of the roof, after having been covered by the shingles. w-ill be pleasing to the eye. A further object is to provide Shingles of such shape and laid in such a manner that they will so lap over each other as to form a very effective water proof coat for the roof. Other objects of the invention will appear from a consideration of the accompanying drawings and the following description thereof.
Of the drawing Fig. 1 is a plan view of a single shingle. in its completed shape; Fig.
2 is a diagram indicating the manner in which the shingles are cut from a long strip without any material waste; Fig. 3 indi- Cates the manner in which the shingles are laced together in forming the roof; Fig. 4 is a plan view of a plurality of shingles properly assembled on the roof; and Fig. 5 is anedge view of the shingles of F 1g. 4.
It is common to make Shingles out of various Substances which4 have been formed into sheets, and which are impregnated with preserving and water proof substances. So far as Inv invention is concerned the material of which mv shingles is composed is immaterial, as well as the substance which impregnates or coats the same; but I prefer for the purpose substances which may 'be formed into sheets or long strips, and then may be conveniently cut by means of diesl or otherwise into individual units, and whlch lare to be applied to the roof in general in a manner somewhat similar to the ordinary manner of applying such shingles. Shingles made in this manner when applied to the roof, being more or less pliable, the exposed portions of the shingles are some times blown upwardly by the Wind, or are other wise bent out of shape, and the consequence 1s that the appearance of the roof is objectionable. and the protection of the roof is more or less diminished. The portion of the shingle which is thus deformed, iS usually the portion which proiects below the overlying upper shingles, and, in order to prevent this deformation, I provide means for locking the lower ends of the shingles to the adjacent shingles.
In general the shingles which I provide are T shaped and comprise a main or top portion l0 with a projecting or shank p0rtion 11, the shank portion being that portion which overlies the adjacent shingles and the top portion being covered by the adjacent shingles. As the shank 11 is thus the exposed portion, and the portion most likely to become deformed, I provide tongues or lugs 12 on the lower edges of the Shanks 11, and these lugs are adapted to slip under the Shoulders 20 of the adjacent shingles, as indicated in Fig. 4. In order to lock these lugs 12 to the roof by the adjacent shingles I provide slots 13, arranged so that the lugs 12 of each shingle may pass through the slots of the adjacent Shingles. For instance, in laying the shingles the units 14l and l5 (Fig. 4) are first laid and the unit 16 then has one of its 4 lugs 12 locked under the shingle 14 and the other lug locked under the shingle 15 in the following manner: The lower end 17 of the shingle 16 is of such length and width that it passesl into the space formed between the two shingles 14 and 15; and the lugs 12 may then pass under the shoulders- 20 of the underlying Shingles 14 and 15.; and the shingle 16 then may be pulled upwardly, the lugs 12 passing through the slots 1 3 of the underlying shingles, so that when the shingle 16 is pulled upwardly to its proper place it will occupy the position indicated in Fig. 4 with reference to the underlying shingles 14 and 15 and its lugs 12 are then locked firmly in place by means of the Shanks 11 of the shingles 14 and 15.
Referring to Fig. 4 it will be seen that the exposed portion of each of the shingles forms a uar'e like figure 21, the inclined sides of w ich are more or less regular, so that the appearance of the roof as a whole, while symmetrical, is not painfully plain, but presents a very pleasm appearance. This appearance is increase by the fact that, as is indicated in Fig. 5, the lower edge of each of the exposed portions in flush with the lower edges of 'the main portions 10 of the two adjoining shingles,so that there 1s a double butt portion 22 formin in each case the lower edge of the expose portion; and this gives to the` roof the ordinary double butt arrangement of shingles, and thus improves the appearance by iving a. decided line of demarcation along t e lower edge of the shingle. Further it will be noticed that in laying the shingles in the manner described, when any portion of the roof covering is completed, the lapping of the shingles over the various edges is such that there is no probability of moisture working through to the roof, as the lapping is very material in each case, and comprises, so far as each inclined edge is concerned, a double lapping thereof.
ttention is called to the fact that, although I have shown and described vari ous details of the particular shape of the shingles, particularly with reference to the shank portions 11 yet, in general, the shingle comprises merely a rectangular top portion 10 with a rectangular shank 11 attached thereto in the form of a T; and the laying of the shingles, ex'cept for the lockingsthereof and the appearance thereof, is su tantially the same as if plain rectangular T-shaped shingles were used without the locking means. And it will further be noticed that the cutting out of the individual units from the strips of material, whether the plain or the locking units are used, can be, performed without an waste of material, by cutting out the umts substantially as indicated in Fig. 2. With. particular reference to the exact form indicated in Fig. 1 it will be seen that the lugs 12 of one shingle are formed by cutting out the recesses 18 of the adjacent shingles, the dimensions of the lugs in the recesses being similar, and the portions 11 as a whole are formed by cuttingout the lar e corners from the adjacent shingles. o that there is no waste of material so far as cutting out of the units as a whole is concerned. The material cutout from the slots 13, however, is not made use of so far as the shingles themselvesV are concerned. In general the shape of the shingle is such that they may be readily cut from long stripsof material, and hence are easily and cheaply manufactured, and at the same time they may be laid so asto' form a very leasing and efective covering for the roo and Yone in which the shingles will not become deformed by any ordlnary means.
Although my invention may be carried out with shingles of other relative dimensions, yet the relative dimensions which I prefer are as follows: The length of the top portion 10 is twice the distance hetween the inner edges of the slots, or twice the average width of the shank, measured on a line parallel with the top; and the width of the trg) is twice the length of the shank or the istance the shank projects awa from the to as is indicated by Fig. 1. e length o each lug 12 is equal to the length of each recess 18; and the length of the outer end of the shank'including the two lugs, is twice the distance from the edge of the shank where it joins the top to the adjacent end of the top.
