CLASP OR FASTENER.

SPECIFICATION formingpart of Letters Patent No. 709,536, dated September 23, 1902. Application filed December 12, 1898. Serial No. 699,016. (No model.)

To all whom it may concern.

Be it known that I, NEWTON CRANE, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Clasps or Fasteners, of which the following is a specification.

This invention has relation to clasps or fasteners, and while particularly adapted for use on shoes and those overshoes which are known as arctics, yet may be equally well employed for securing together the two meeting edges of a garment or any other article of wear or manufacture.

The objects of the inventiop are, first, to provide a fastener whose members may be attached and detached with readiness and with little exertion and which will not become accidentally displaced while subjected to or dinary wear and usage; second, to provide yielding means for holding the two members in engagement while in their operative positions, and thereby enable me to use them on articles constructed of comparatively stiff unyielding material, and, third, to provide a clasp or fastener in which the parts shall consist of members each formed of an integral strip or piece of metal died or stamped into shape,whereby expensive machine-work may be obviated and the cost of producing the fastener be made relatively low.

To these ends the invention consists of a fastener of the character described possessing certain features of construction and relative arrangement of parts, all as illustrated upon the accompanying drawings, described in the following specification, and pointed out in the claims hereto appended.

Reference is to be had to the accompanying drawings, and to the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 represents in plan or edge view a fastener or clasp embodying my invention. Fig. 2 represents a front view of the same. Figs. 3 and 4. are plan or edge views, partially in section, showing the two members of the clasp as engaged and being disengaged, respectively. Fig. 5 represents a perspective view of the spring-loop to which one of the members is attached and by whichit is held in engagement with the other member.

in width to receive the member a.

Referring to the drawings, which show one embodiment of the invention, the two complemental members are indicated by a and b, respectively. The member a is longitudinally curved and is provided at its edges with a plurality of notches a a, which form engaging shoulders a a which are at right angles to the median line of the said member. The outer end of the said member is apertured at a to receive a metallic loop 0, which may be riveted or secured, as at c, to the upper of a shoe or the flap of an overshoe. Said loop is formed of a strip of metal bent upon itself, as shown, the space at the bent end between the two legs of the strip beinglarge enough to permit the cross-bar a at the end of the member a to turn therein.

The member I) is formed of a flat plate of metal which is bent at its front or inner end I) and is formed with an aperture 1) adequate The aperture b is contracted at the front portion of the member to form two shoulders 79 b which are adapted to engage the shoulders a a on the member a, said contracted portion of the aperture being wide enough to receive the narrow portion of the member a formed between the notches a. A metallic loop dis passed through the aperture 1) in the member Z), as shown in Figs. 3 and f. This loop dis also formed of spring metal and forms a bearing for the cross-bar or pintle b at the outer or rear end of the member Z). The loop is cut away, as shown, to form two bearings d d, and between them is a spring tongue d which is slightly bent at its free end to bear against the inner face of the pintle b. The cross-bar or pintle b is oblong in section, so as to provide two faces at an angle to each other, whereby the spring may bear flat against either of said faces to hold the member I) in an operative or inoperative position. I

In order to engage the members, the member 19 is rotated in the loop about the pintle b as an axis into the position shown in Fig. 4:, where it is substantially at right angles to the member a, and the spring (1 hearing against a flat face on the cross-bar or pintle b holds the member in that position. The said member a is then passed through the aperture b and the member I) is thrown into the position shown in Fig. 3. The end of the member a rests upon the outer surface of the loop, and hence the members are maintained in their engaged positions against accidental displacement by the said spring, which bears against a flat face of the pintle b. The action of the spring is to force the member I) toward its operative or inoperative position from a neutral position midway between the two. This combination of the engaging members and the spring-loop is especially desirable where the fastener is employed on brogans and other articles that are comparatively stiff and where the members are liable to be disengaged, and consequently, so far as the present invention is concerned, it is not limited to the precise construction of members which I have illustrated and described, since the springloop may be employed in connection with other fasteners.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes ofits use, I declare that what I claim is 1. A clasp or fastener comprising two complemental members, one beingelongated with a plurality of engaging shoulders inits edges and the other having a transverse aperture to receive the first said member, said aperture being contracted at its front end whereby the end wall of the aperture provides shoulders 19 to engage the said first-mentioned shoulders.

2. A clasp or fastener comprising two complemental members each formed of sheet metal and each having means at its outer end for attachment to a shoe or garment, one of said members being elongated with a pinrality of engaging shoulders on its edges, and the other having an aperture between its ends to receive the first-mentioned member,

said aperture being contracted at its front end to provide shoulders to engage the firstmentioned shoulders, whereby the elongated member may be passed through the aperture in the apertured member and by its engagement with both faces thereof be held with its shoulders in firm contact with the shoulders of the said apertured member.

3. A clasp or fastener comprising two complemental detachable members and an attaching-loop for one of said members, said loop consisting of a metallic strip doubled upon itself and being cut away to provide a resilient tongue with its end at or near the bend in the loop to normally hold said members in engagement.

4. A clasp or fastener comprising two complemental detachable members having engaging parts, one of said members having a cross-bar or pintle at its outer end, and an attaching-loop for encircling said cross-bar or pintle, said loop consisting ofa metallic strip doubled upon itself and being cut away to provide a spring-tongue to bear against said cross-bar or pintle and hold said member in either of two positions.

5. A clasp or fastener comprising two complemental detachable members having engaging parts,-one of said members having a crossbar or pintleat its outer end, and an attaching-loop for encircling said cross-bar or pintle, said loop being formed of a single strip of resilient metal bent upon itself, and having a spring-tongue integral therewith extending into the space between its two portions, and bearing against said cr0ssbar, substantially as set forth.

In testimony WhereofI have affixed my signature in presence of two witnesses.
