To all whom it may concern: 7

Be it known that I, CLARENCE E. SMITH, a citizen of the United States, residing at New Britain, county of Hartford, State of Connectiout, have invented certain new and useful Improvementsin FasteningDevices,of which the following is a full, clear, and exact description.

My invention relates to a fastening device,

and while especially applicable for use on horse-clothing it may be used to advantage as applied to articles of personal wearing-apparel-e. g., belts.

Among the main objects of my invention I 5 are simplicity and durability of construction,

efl'ectiveness, and ease of operation.

The purpose of the invention is mainly to provide a simple and inexpensive and efieetive fastening formed of two parts, one of 26 which may be engaged with the other in such manner that both are held from accidental disengagement.

In the drawings, Figure 1 is an elevation Fig. 2 is an eleva of one of the members. e 5 tion of the other member. Fig. 3 is an elevation of the two members shown in Figs. 1 and 2, said members appearing in the position in which they are first placed while connecting them together. Fig. 4 is an elevation showing the two members connected with one another. Fig. 5 is an edge View of the members as shown in Fig. 4.

The fastening device comprises two members, each of which is in the form of a hook having a plurality of hook-bills. A is a loop or other suitable means to secure the one member to thegarment. This member includes,besides the loop A,the hooks B B, having the outwardly-extending bills 0 b b. The bends are made so that these bills are located in practically the plane of the shank of the hookand are oppositely arranged, as clearly seen in the drawings. The extremities of the bills are preferably bent outwardly, as shown, to facilitate the. engaging of the parts in the manner hereinafter described. The shanks of the bills I? I) lie closely together, but are preferably not socured together, and consequently they may spring apart for the purpose hereinafter de scribed.

C is a loop or other suitable means for fastening the other member to the garment, and the other member comprises not only the eye or loop C, but also the peculiarly-shaped hooks D D. The hook-shanks D Darebent inwardly and then away from each other, as shown in Fig. 2, and the ends are not only turned up to form the bills (1 d, but they are 'also turned inwardly before being turned into the bills, so as to form a compound curve, one of said curves lyingin ahorizontal plane, while the plane determined-by the bill of each hook is perpendicular to said horizontal plane, or practically so.

By the double arrangement of books upon each of the members and by forming the member A of spring metal and proportioning the space between the bills 01 d properly with respect to the spaces Within the hooks -B B when the parts are being placed together the hooks D D tend to separate the hooks B B, while the tendency of the bills (1 d is also -to separate the bills b b away from their shanks B B. This action produces atension between the parts,which tends to prevent anyloose play and aids in holding the parts together. By extending the hookbills (1 d outwardly away from each other at an angle, as seen in the drawings, these bills dd act as a wedge. Consequently the members cannot be disengaged until they are swung upon the axis conventionally illustrated by the line X X, Fig. 4:. This swinging of one member upon the other upon this axis causes the hook-bills d d to gradually become freed from engagement with the hooks B B by the spreading action of the hooks d g) 51,31 161 by the compressing action of the hooks The parts are assembled by placingthem in the position shown in Fig.3, in which the bills 61 d of the hooks on one member. lieadjacent the entrance-passage into the hooks B B upon the other member. The space between the bills b b is less than the space between the hooks on the other member. Consequently the shanks yield sufficiently to let hooks B B D D are snapped into the engagement shown in Fig. 4, wherein for the reasons hereinbefore stated accidental disengagement is practically impossible.

What I claim, and desire to secure by Letters Patent, is-

1. In a fastening device in combination, a pair of hook members one of said members providing two oppositely-arranged hooks having free ends and lying in the same plane, the width of the entrance-passage between said hooks being less than the Width of the holding-pocket within said hooks, the other member carrying two hooks lying in different planes from the plane of the fastening device and from each other, the said hooks being offset and inclined at an angle to produce an opening-wedge.

2. In a fastening device in combination, a pair of hook members each of said members being provided with a pair of free -ended hooks, each of the hook-bills on one member being located in substantially the same plane relatively to the shank portion thereof, the

width of the entrance-passage between said hooks being less than the width of the hold ing-pocket within said books, the other of said members being provided with a pair of hookbills projecting laterally out of the plane common to the hook-shanks and inclining away from each other to form an opening-wedge to the other member.

v 3. A fastening device comprising two hook members adapted to coact with each other, one of said members having shanks, tending to spring toward each other,curved outwardly and the ends bent back, the width of the entrance-passage between said hooks being less than the width of the holding-pocket within said hooks, the other of said members having shanks provided with free-ended bills, curved outwardly and the ends bent up and offset from the common plane of said shanks, so as to make it necessary to separate the ends of said first member when disengaging the two.

4.. A fastening device comprising a pair of hook members adapted to coact with each other, one of said members having shanks curved outwardly and the ends bent back, the width of the entrance-passage between said hooks being less than the width of the holding-pocket within said hooks, the other of, said members having shanks whose ends are bent upwardly and outwardly, the two members being so proportioned that the ends of the first member are caused to be sprung outwardly when drawing the two members together and then will spring back to securely lock the two together, the ends of each pair of books being free.
