EDWIN BALL STIMPSON, NEW YORK, N. Y.

FASTENER.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed September 22,1906. Serial No- 335,789.

To all whom it may concern:

Be it known that I, EDWIN B. STIMPsoN, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to certain improvements in fastening devices such as are commonly employed upon leggings, arctic overshoes and the like, and has for its object to provide a fastening of this general character of a simple and comparatively inexpensive nature and of a light, strong and durable construction by means of which the overlapping sides or edge portions of the legging or other article may be securely and conveniently fastened and held to prevent the sides or edge portions from gaping open.

The invention consists in 'certain novel features of the construction and combinations and arrangements of the several parts of the improved legging fastener, whereby certain important advantages are attained and the device is rendered simpler, cheaper and otherwise better adapted and more convenient for use all as will be hereinafter fully set forth.

The novel features of the invention defined in the claims.

In the accompanying drawings, which illustrate an embodiment of the invention-Figure l is a View of the fastener wherein the plate-member is in longitudinal, vertical section at line x1 in Fig. 2, the hook and its base-plate being in side elevation g and Fig. 2 is a plan of the same. before the transverse bars and the aperture are fully formed, showing the mode of construction. Figs. 4 and 5 illustrate a slightly different mode of attaining the same object; the former being a longitudinal section of the finished plate and the latter a plan of the unfinished plate. These will be fully hereinafter described. Fig. 6 is a plan similar to Fig. 2, but showing a double device. Fig. 7 is a sectional view taken lengthwise through a fastener plate constructed according to my invention, said plate being shown in a modified construction wherein the cut out portions of the plate are bent upwardly and lapped upon the top surface of the plate to produce the reinforces, and Fig. 8 is a sectional view similar to Fig. l, but showing the improved fastener plate applied over an aperture prowill be carefully duced in the edge portion of the legging or other article to which the fastener is applied for use, so that the hook-like member is adapted to pass through such aperture of the edge portion of said legging or other article.

Referring primarily to Figs. l, 2 and 3,-`A designates one part of an article on which the fastener is mounted and B designates the other part thereof. The purpose of the fastener is to draw and connect together these parts, which will be usually made of some flexible fabric. Secured to the fabric A, by a rivet l for example,

Fig. 3 is a plan of the plate as it appears` is a plate 2, having inzit an oblong, or elongated aperture divided into several apertures 3, by cross-bars 4. l Secured to the fabric B is the other member of the fastener, comprising a base-plate 5, secured to the fabric by rivets 6 for example, and having connected to it a hinged spring hook 7, adapted to pass through an aperture in the plate and engage one of the bars 4 therein. So far as described the construction, generally is the common one, but in making the plate 2 in the ordinary way it has been customary to simply punch out parts of the plate to form the several apertures therein, leaving a narrow bar or bridge between the apertures for the hook to engage.

In the present construction (see Fig. 3) in punching out or displacing the metal to form the apertures the metal is slitted so as to form in each aperture two fiaps 8, free only at their ends and one side and these flaps are bent down (along the dotted lines in Fig. 3) and under the bar so as to give to the latter a rounded form and a double thickness of the metal, as clearly shown in Fig. l. This construction provides a thickened and convex surface for the curved hook to engage, and strengthens the bar materially. l

In the construction as described with reference to Figs. l and 3, the displaced metal in each aperture -is divided, one section being folded back under the bar at'one side and the other section back under the bar at the other side; and the surplus is folded, at the margins of the terminal apertures, under the metal of the endportions of the plate 2, as seen at a in Fig. l. The surplus metal displaced from an aperture may as well, however, be comprised in a singleiiap and this fiap be folded under the adjacent cross-bar. This is illustrated in Figs. 4 and 5. In following this variant the iiap will, by preference, be left integral with that edge of the cross-bar upon which the hook bears, so as to provide at that edge a good bearing for the hook.

The object of the invention is, as will be seen, to utilize the waste material of the plate to reinforce and give a rounded contour to the transverse bars.

Obviously the invention is not limited to the exact form of the bar when the latter is seen in cross-section; nor is it essential that the material displaced shall be turned under the plate as seen at a at the left in Fig. l. This is the attached end of the plate and the hook will never engage this margin, so that this fiap 8 might be removed. For uniformity, however, the construction shown in Fig. l is preferred.

Fig. 6 is a view showing two hooks 7 on a broad plate 5, and a broad double plate 2, as will be readily understood. Obviously this is a mere duplication of the device seen in Fig. 2.

Ordinarily the surplus metal forming the flaps 8 will be folded downward or on the underside of the plate, but they may be folded upwardly upon the top surface of the fastener plate, as shown at 10 in Fig. 7, as well;

Having thus described my invention, I claim- 1. As a new article of manufacture, a fastener: plate of thin at metal having` apertures produced in a longitudinal series, a portion of the metal of said plate at each such aperture being integrally attached to said plate along the side of said aperture and being folded ilush along said side of the aperture and forming a reinforce of increased thickness extended along said side of such aperture for en ran`- ment with a member passed through said aperture.

2. As a new article of manufacture, a fastener plate of thin at metal having apertures produced in a longitudinal series, the metal removed from said plate to produce each such aperture being integrally attached to said plate alone' one side of said aperture and being folded ilush against the body portion of the plate alongsaid side of the aperture and forming a rounded reinforce of increased thickness cxtended along said side of such aperture )for cneagcuunt with a member passed through said aperture.

In witness whereof I have hereunto signed my name this 21st day of September' 1906, in the presence o1 two subscribingr witnesses.
