FABTENER COMPANY, OF MEAIDVILLE, P

SYLVANIA OF MEADVILLE, PENNSYLVANIA,' ASSIGNOB TO HOOKLEBB ENNSYLVANIA, A CORPORATION 01 rm- SEPABABLE msrmrna Application as m a, 1927. Serial no. 189,198.

This invention relates to separable interlocking fasteners and has for its object to provide improved means for separatm fastener stringers at both ends, and for facllitat- 5 ing reengagement with the interlocking members in their proper relative positions.

According to a feature of the invention,

the stringers are provided at their lower extremities with interlocking connecting mem- 19 bers which serve to start the opposed interlocking members proper sequence brought together. vent the stringers into engagement in the when the stringers are These members also prefrom separating at the i 5 bottom when the fastener is closed. When the fastener is opened the stringer carrying one series of interlocking members, together with its associated connecting member, may be slipped through the slider and released 20 from contact with the rest of the fastener.

The members comprising the separable connecting device of this invention are simple in'construction, efficient in operation and capable of withstanding continuous hard usage These connecting members may be stamped from flattened wire similar to that employed in the manufacture of the standard interlocking ,fastener members, thus reducing the cost of '50 production to a minimum.

The invention will be described in connection with the accompanying drawing in which similar reference characters designate corresponding parts in the several views, and

Fig. 1 is a plan view of a separable fastener embodying the invention; Fig. 2 is a view similar to Fig. 1, showing the-fastener in position to be opened or closed; a

Fig. 3 is a plan view of the slider having a hook portion for holding it on one stringer when the fastener is open at the bottom;

and

carrying interlocking members 12 arranged in staggered relation. The slider 13 having diverging channels is movable up and down along the stringers by means of any suitable pull member (not shown) to close or release the opposed interlocking members.

Separable

end connecting members

14 and 15 are mounted near the lower ends of stringers 10 and 11, respectively, and act as guides to start the opposed interlocking members 12 into engagement in the proper order, and also serve to lock the stringers against openmg at the bottom when the fastener is closed. The connectin member 14, shown in Fig. 4,

includes clamping jaws 16 for clamping it on the corded edge of the stringer 10, a. plurality of angular teeth or projections 17, separated by correspondingly shaped notches and a lower pro ection 18. The connecting member 15, shown in Fig. 5, includes clamping jaws 19 for clamping it on the corded edge of the stringer 11, a plurality of angular teeth20, a recess 21 and a stop pin 22. The projections or teeth 20 of the member 15 fit into and cooperate with the angular notches between the teeth 17 on the adjacent edge of the member 14 when the fastener is being closed from the bottom, thereby starting the opposed interlocking members 12 into engagement in their proper relative positions, as shown in Fig. 1. When the connecting guide members are in engagement, as shown in Fig. 1, the projection 18 of the member 14 rests within the recess 21 in the member 15, thereby preventing the fastener from coming apart at the bottom.

The foreplate of the slider 13 is provided with a hook portion 23 which rides into engagement with the stop pin 22 when the slider approaches the lower limit of its travel. Hence, when the slider is in the lower position shown in Fig. 2, the hook portion 23 engages the stop pin 22 and prevents the slider from falling off the stringer 11.

When the slider 13 is' moved from the position shown in Fig. 1 to the lower position shown in Fig. 2, progressively disengaging the opposed interlocking members 12, the

lowing the stringer 10 to be drawn through the split edge of the slider so that the fastener is completely open at the bottom as well as at the top. In this position, it will 5 be seen that the hook portion 23 of the slider enga es the stop pin 22 of the connecting mom or 15, so that the slider always remains on the stringer 11. The relative stiffness of the fastener tends to maintain the slider in this position until the two stringers are again brought together and the slider moved up- Wardly to 'reengage the teeth of the connecting members and the interlocking members 12. The stringers preferably extend below the connecting members 14 and 15 a sufficient distance to permit the operator to grasp the free ends of the stringers with one hand while actuating the slider with the other hand. This construction permits the mem ber 14 to be pulled downwardly through the slider and held in cooperative engagement with the member 15 when the slider begins its upward travel.

It will be obvious that the invention is not to be restricted to the precise construction herein shown and described. Many of the details, such as the structure of the stringers, interlocking members and slider, will necessarily vary according to the particular uses for which the fastener is designed. The construction of the end connecting members may also vary widely within the scope of the appended claims.

The invention claimed is: 1. A separable fastener comprising a pair of stringers having opposed series of interlocking members, a slider movable along said stringers to engage and disengage saidl members, a member having a plurality of teeth mounted on one stringer, and a member having a plurality of teeth mounted on the other stringer and arranged to mesh with the teeth of said first mentioned member to guide said interlocking members into engagement in the proper sequence.

2.
