FASTENER FOR ROOFING.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed November 19. 1906. Qerial No. 343.994.

To all whom it may concern:

B e 1t known that 1, AUGUST E. RoEvER, a citizen of the United States, resident of Buffalo, county of Erie, and State of New York, have invented a new and useful Improvement in Fasteners for Roofing, of which the following is a specification, the principle of the invention belng herein explained, and the best mode in which I have contemplated apprlying that principle, so as to distinguish it om other inventions.

My invention relates toimproved means for securing roofing, to the roof-boards, particularly prepared roofing, such as tarred felt, granite roofing, and the like, which usually comes in long strips made up in the form of rolls. While thus primarily designed for use with roofing of this character, it will be obvious that the device in handis capable of quite general application, wherever the several advantageous features presented by such fastener are ap reciated.

Said invention, t en, consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following descri tion set forth in detail certain means embo ying the invention, such 'disclosed means constituting but one of various forms in which the principle of the invention may be used.

In said annexed drawing: Figure 1 represents in perspective a broken section of roofing, in connection with which my improved fastener has been utilized -for securing the same to the roof paper; Fig. 2 is a transverse cross section through a section of such roofing, showing in side elevation one of my fasteners in site; Fig. 3 is a perspective view of one form of my fastener as it appears previous to its application to the roofing; and Fig. 4 represents, .likevfi'se in erspective, a slightly modifiedform of such astener.

The method practically universally employed for securing prepared roofing material to the roof, as is well known, consists simply in tacking down the overlapping edges of such roofing. Washers-are usually employed in connectlon with the nails, or

else nails with broad heads, in order to secure abroad bearin surface and to prevent the heads of the nai s from breaking through the roofing material. The only recaution taken to prevent leakage at t e several oints of attachment, the roofing material eing .obviously punctured, has been to spread over the same a coating of tar or waterproofing material.

The above method of attaching roofing has long been considered objectionable, but its use has continued for want of a suitable substitute for the nails. Among other objections there may be enumerated the fact that the boards of the roof usually shrink more or less after the construction of a building, and such shrinkage causes the relative movement of the nails thereby tearing the material and leaving a space around the nail through which water may enter. This defeet is accentuated by the expansion and contraction to which changes of tern erature subject the roofing material itse the general result being that, in the course of a relatively short time, the roofing has worked loose about the nails sufficiently to allow the entrance of moisture, with the consequent very rapid deterioration both of the adjaterial being torn as already noted, there is a pronounced tendency forthe nail to' actually Work entirely loose and dro out of the roofing. Obviously the hole t us left in such roofing is a fruitful cause of trouble, as any person of experience with roofs of this kind can witness.

The device which I propose to utilize in place of nails for securing the roofing material to the roof comprises in its simplest form, Fig. 3, merely a narrow metallic str1 Aformed With anaperture a near one en adapted to allow the passage therethrough of a nail for the purpose of attaching the strip to the roof boards. The other end of the strip is doubled over upon itself, the doubled-over portion a terminating short of the nail-receiving aperture 0 and being provided with a transversely-dis osed prong a this prong is of en stantially tria and is slightly recurved, that is, 1ts oint is inclined towards the doubled-over on of the fastener. In the modified form (if fastener shown in Fig. 4, no change is made from the construction just descrlbed except that, in place of being formed with an opening for the reception of a nail, by means of which the lar form,

fastener is designed to be tacked fast, such under portion of the fastener is formed with an integral downwardly-turned point a. This oint is designed to be utilized in tacking tl e fastener down, thus much simplifying the operation and rendering unnecessary the use of any nails whatever.

In applying the fastener as will be evident om an inspection of Figs. 1 and.2, the main portion, referred to as the under portion: in the above description, is nailed down either by means of a nail through opening a or by means of the integral point a where the latter form is used, along the upper edge of the undermost of the overlapping sheets 0f roofing material. The u per sheet is then moved into place so as to ave its lower edge clas ed between such under portion and the dou led-over portion a of the fastener. The doubled-over portion a is thereupon hammered down, the transversely-disposed prong a piercing such uppers-layer of roofing and being clenched upon'fthe under portion, as clearly shown in Fig. 2. The point where such iercing of the upper layer takes place, it is o vious from'the relative lengths of the two portions of the fastener as above delineated, will be some distance below the point of attachment of the fastener, or, in other words, the point where the lower sheet of roofing is pierced. Any moisture, hence,

that will percolate through the uncture in the upper sheet, it is obvious, escape between the sheets downwardly without running across or in proximity to the o ening in the lower sheet, The roof boar s underneath are hence kept absolutely dry. At the same time, both sheets are very securely held in place, for the upper ed e of the under sheet is nailed down in muc the same fashion as in the old method, while the lower edge of the upper sheet is equally securelyheld down by the fastener which clasps it and, by being clenched in the manner described, makes release of the sheet impossible. Where it becomes necessary to have two sheets overlap laterally, as only infrequently happens where the roofing is horizontally disposed in order to piece out a short sheet of the material, or

as will be almost entirely the case in the use ofvertically dis osed roofing, my improved fastener can stil be used with equally efficacious results in securely clenching such roofing in lace while preventing the passage of water t erethrough. It only becomes necessaryin this use of the fastener to dispose the same at a slight downward inclination to the vertical line of the lap, in order that the water may not follow the under portion of the fastener to the point where the under layer of roofing is pierced, as it might do if the clip were horizontally disposed. To innsure the i proper disposition, therefore, of the fastener when utilized in this latter connection, I preferably form the same not out of a straight metal strip, as in the case of the standard form of fastener as above, but out of one of V form, whereby, upon being doubled over, the form A, shown in Fig. 1, results, difiering only from the standard form in that the doubled-over edge of the fastener is at an angle with its lateral edges instead of being at right angles thereto, as in the standard form. The method of attachment and the clenching of the upper doubled-over ortion is exactly the same in this case as t e form first described.

It will be seen, from the foregoin description, that by the employment 0 this type of fastener in place 0' nails or the like, a perfect joint is secured, without sacrificing in the least the permanence with which the roofing .is held down. It is immaterial whether the timbers of the roof shrink or not, or whether, because of shiftin of the roofing sheets with the alternation of summer heat and winter cold, such sheets be drawn more or less from about the nail-heads, for these are at all times securely covered over with the upper-sheet. At the same time, such upper sheet is just as firmly bound to the lower as though the nail in question actually pierced it also. Such fastener has the further advantage of being quite inexpensive. In fact, in material it does not represent a much greater outlay than the old-fashioned washer heretofore used in connection with the nails. Its attachment, furthermore, invo ves the use of no new tools nor the expenditure of much additional labor, while the results above noted as being obtained by its use 1 clearly commend its general employment for the purpose stated.

Having thus described In invention in detail, that which I particu arly point out and distinctly claim, is

1. A fastener for roofing comprising a metallic strip doubled over upon itself, the doubled-over ortion being provided with a prong adapte to be driven through the roofmg material to contact with the lower portion of said metallic strip. T
