Definitions

  • This invention relates to separable interlocking fasteners and has for its object to provide improved means for separating fastener stringers at both ends, and for facilitating reengagement with the interlocking members in their proper relativc'positions.
  • the fastener stringers are provided adjacent their lower ends with cooperating members which can be instantly separated without unhooking or other special manipulation, permitting the stringers to be completely separated, and when brought together serve to start the interlocking members on the stringers into engagement in the proper sequence.
  • the member on one stringer is provided with a sheath or socket which receives the lower edge of the other stringer. thereby connecting the stringers together and preventing separation under transverse strain.
  • This member also acts as a stop for the slider and serves to maintain the slider and socket in the proper posit-ions toereceive the detached stringer when the parts are to be connected together after separation.
  • the cooperating member on the second or detachable stringer is formed so that it can be drawn through the slider, and is provided with an obstructing portion which interferes with the interlocking members on the opposed stringer and prevents the fastener from being closed except when the parts are brought together in the proper starting position.
  • the lower portion of this detachable stringer is preferably treated with stiffening material to facilitate threading through the slider and the socket of the opposed connecting mem- 0 ber.
  • Fig. 1 is a plan view of a separable fastener embodying the invention
  • Fig. 2 is a view similar to Fig. 1 with the stringers in a relative position incapable of being closed;
  • Fig. 3 is an isometric'view showing the connecting member of one of the stringers.
  • Fig. 4 is an isometric view showing the cooperating member of the opposite stringer.
  • Fig. 5 is a detail sectional View on line 55 of Fig. 1.
  • Figs. 1 and 2 flexible stringers 1 and 2 are provided with the usual corded edges carrying interlocking members 3 arranged in staggered relation.
  • the slider 4 having diverging channels is movable up and down along the stringers by means of any suitable pull member (not shown) to engage or disengage the opposed interlockii'ig members.
  • the connecting member .6 shown in detail in Fig. 3, comprises spaced pairs of clamping jaws 7 for clamping the corded edge of the stringer 2, side plates v8 intermediate the pairs of clamping jaws and having inturned edges 8 and forming a socket or sheath with an opening in the outer edge parallel to the edge of the stringer i for receiving the corded edge of the stringer 1. and a portion 9 the purpose of which is hereinafter described.
  • the member 5 shown in detail in Fig. 4 comprises clamping jaws 10 for clamping the corded edge of the stringer 1, and a thickened portion 11, the purpose of which is hereinafter described.
  • the members 5 and 6 WVith the members 5 and 6 in the position arranged in the proper vertical position to insure the engagement of the opposed interlocking members 3 :in the proper order. Furthermore, when the fastener is closed the socket formed by the side plates 8 and edges 8 of the member 6 partially surround the corded edge of the stringer 1 thereby preventing the fastener from being opened at the bottom when a transverse strain is applied to the fastener.
  • the thickened edge of the stringer 1 is stiffened at the point where it is engaged by the side plates 8, as described below.
  • the lower end 12, below the point where lateral strain is applied, is also stiffened and acts as a guide for threading the stringer 1 into the slider and the socket of the member 6.
  • the stringer 1 may readily be drawn up through the split edge of the slider and the side plates 8 of the connecting member 6 and thus be completely disengaged from the'rest of the fastener.
  • the side plates 8 ofthe member 6 act as a stop for the slider as seen in Fig. 5 so that the slider will always remain on the stringer 2.
  • the portion 9 of member 6 extends into the slider and is so shaped as to provide edge guiding surfaces which prevent the member from twisting out of the vertical plane of the slider.
  • the socket formed by the side plates 8 will always be in alignment with the slider and in a position to receive the corded edge of stringer 1 when it is inserted therein through the slider.
  • the thickened port-ion 11 of the member 5- acts as a stop to prevent the fastener from being closed except when the stringers are in the proper vertical position shown in Fig. 1 with the members 5 and 6 contacting.
  • the action of the member 5 in preventing the fastener from closing in one situation is illustrated in Fig. 2. It will be seen that the thickened portion 11 of the member 5 interferes with the interlocking members 3 of the stringer 2, preventing the slider 4 from being drawn up when the several elements of the fastener are not in the proper starting position.
  • the free end of the stringer l which extends below the member 5 is preferably treated, either across the width of the stringer or only at the thickened edge, with a substance which renders this part of the stringer stiff, yet sufficiently flexible, in order to facilitate its entering into the sheath of the member 6.
  • the stiffening material employed for this purpose may be rubber, shellac, collodion or any other suitable sizing which stiffens in drying, and afterwards retains a certain amount of flexibility. If desired, celluloid may be pressed upon the stringer in a mould and heat applied "to amalgamate it with the fabric in the desired shape. The stiffening at the edge of the stringer 1 immediately below the member 5 prevents it from buckling under lateral strain at this point where it is engaged by the inturned edges of the side plates 8.
  • interlocking members and slider will necessarily vary according to the particular uses for which the fastener is designed.
  • the construction of the cooperating end connecting members may also vary widely within the scope of the appended claims.
