Fig. is a perspective view of the end connecting parts for the modification shown in Figs. 17 to 21 inclusive:

Fig. 26 is a perspective view of a slider adapted for use with the form of invention shown in Figs. 2 to 16 inclusive.

Referring' to Figs. 1 to a of .the drawings, the

numerals 10 and 12 designate stringers preferably made of woven material having secured thereto cords 14 and 16 respectively to form beaded edges to which the opposed series of locking elements 18 and 20 are respectively connected. Stringer 12 is provided at one end with a receiving member 22. that cooperates with a complementary entering member 24 that is secured to one end of the stringer 10 to provide with receiving member 22 an end closure for the stringers. A sliding device 26 is carried by stringer 12 and is adapted to be positioned at the closure end to receive the entering member 24 and to eflect a locking engagement between the receiving and entering members in a manner hereinafter described.

The receiving member 22 is preferably formed from a strip of sheet metal, from which a stamping as shown in Fig. 8 is out, whose sides being provided with transverse aligned cuts 28 and 30 will allow the split portions of each side to be folded in opposite directions to form angular side plates 32 and jaws 34. As best shown in Fig. 22 these side plates are formed to provide a sheath 36 that is adapted to be securely clamped around the corded edge of the stringer 12 and with parallel extensions or tabs 38 that are spaced to receive therebetween the stringer 12 to which they are secured by a rivet 40 or the like. The sheath 36' is preferably of the thickness of the interlocking members so as to pass freely between the walls'42 and 44 of the sliding device. 26 that is manually operated to lock and unlock the locking elements 18 and 20, by a to-and-fromovement, respectively. The jaws 84 are spaced and have their ends abutting to form a socket to receive a complementary engaging portion of the entering member. For purposes of preventing the sliding device from passing off the receiving member, the Jaws are formed to have an overall dimension greater than the spacing between the walls and thus serve as a stop toprevent the removal of the sliding device from stringer 12 at that end.

The entering member is also formed from a 'piece of sheet metal, from which a blank as shown in Fig. 'l is punched and formed. The sides of the blank are L-shaped and folded back upon themselves to form an L-shaped member with side plates 46 and tabs 48 in spaced relation to receive the end of stringer 10 to which the tabs 48 are attached by a rivet 50. The side plates are similarly shaped and provided with lugs 52. In their folded position they provide an engaging hook formed by lugs 52, a spacer portion 54 and a camming head portion 56.

The Bilge-81 8 portion 52 is hook shaped and extends along the inner side and from the outer end of the L shaped'member and is adapted to engage with the socket formed by arms 34 of the receiving member in such a manner that the inner sides of the receiving and entering members will be capable of assuming a parallel relation in the locked position thereof and relative longitudinal movement of these parts will be preadjacent these parts will assume the proper position for interlocking enga ment. The thickness of the engaging portion 52 is such that it will freely pass between the flanged sides 56 and 60 of the sliding device.

The spacer portion 54 is preferably a continuation of the enga portion and is longer than the spaced flanged sides 58 and 60 and'thin enough to pass freely therebetween.

The camming head portion 56 is formed by making the sides 46'rounded at their upper ends and laterally projecting from that portion of the sides that constitutes the spacer portion. The face 62 of the cam is arcuate. The rounded sides of the head portion are sufllciently spaced to constitute a sheath for the stringer and the end of the cord 14 which terminates short of the stringer end, which is cutaway along its inner lower edge corresponding to the position of thespacer portion. The camming portion of the entering member has a thickness greater than the space between the flanged sides of the' slider but less than the space between the walls 42 and 44.

As shown in Fig. 23, the flanged sides 58 and 60 of the slider have cut away portions 61, which extend for a suflicient length so that the head portion 56 may freely pass between the walls 42 and 44. It will be obvious that when the sliding device is moved forward the entering member will be permitted to move laterally into the sliding device and the hooked end will be actuated in fully locked position by the coactionof the flanged sides 58 and 60 and the cam surface 62. when the sliding device is moved to its lowermost limit of travel and the opposed interlocking members are disengaged the stringer 10 may be readily detached from thestringer 12 by a lateral movement of the entering member through and away from the sliding device.

In looking the ends of the stringers together the slidingdevice is passed over the receiving member and is brought to rest .by its outer end abutting against the jaws of the socket, the entering member is then passed laterally and at an angle into the sliding device with the hook in partial engagement with the socket and with the head portion partially within the sliding device. By moving the sliding device forward, the hook will be actuated into complete engagement or locked position with the socket by the camming effect of the cam surface and the inner faces of its corresponding flanged side walls and the two separable parts will be brought into substantially parallel relation with each other and the inner edges of the flexible stringers.

In Figs. 9 to 16 I have shown a modification of 24 and serve as guides and cooperate with other portions of the receiving and entering members for locking the same together. The flanges preferably, but not necessarily, extend across the width of the sliding device for a purpose hereinafter described.

In this variation the receiving member 80 is to limit the movement of the entering member,.

the spacer portion 92 of which is adapted to be received in the space between the tabs 82 and 64. These tabs are provided along their corresponding inner and outer edges with cammed surfaces 94 and 96 respectively so that when the spacer portion of the entering member is inserted between the tabs, the flanges 76 and 78 will first engage their respective cam surfaces 94 at a point inwardly thereof with the lower edge of the spacer contacting with the lowermost part of the lugs, while the cammed surfaces 62 of the head portion 56 will engage with their respective surfaces 96 at a point outwardly thereof and as the entering member is turned the pivot point of the entering member changes along the surface of the tabs until the flanges bear along the entire surface against the cam surfaces 94 and the cam surfaces 62 will have moved along their corresponding surfaces 96 to eifect a wedging or locking engagement between the receiving and entering members.

The slider member used with this form of the invention is shown in Fig. 26 and is constructed identical to that above described in connection with Figs. 1 to 8 except that its outer end is formed with an arcuate portion 96' corresponding to the edges 94.

In the operation of this device the slider is moved to a position where it is stopped by the engagement of the point of the tongue 98 of the slider with the surfaces or edges 96. The thickness of the tongue and the angular surfaces 100 hold the slider in a predetermined angular position corresponding to the angle which the entering member will most likely assume immediately prior to its insertion laterally between the flanges of the slider and the tabs of the receiving member 6 as shown in Fig. 14. When the entering member is in this position, the flanges '76 and 78 are in engagement with the corresponding arcuate ends of both the slider device and the receiving member and as the entering member is turned by hand the sliding device moves upwardly, bringing the cut-away portions 61 out of registry with the cammed head portion 56, as shown in Fig. 13, and thus preventing the entering member from slipping out of partial engagement with the receiving member. A continued movement of the slider will cause the lateral flanges 58 and 60 to engage with the cammed surfaces 62, thus turning the entering member into completely locked position, as shown in Fig. 9.

A further modification of my invention is shown in Figs. 1'1 to 21. In this embodiment the receiving and entering members are constructed in a manner similar to that described in connection with Figs. 1 to 8, these members being formed from blanks as shown in Figs. 20 and 21 respectively.

The receiving and entering blanks are formed with cut-out portions 102 and 104 respectively, so that when their sides are folded back upon themselves along the lines 106 and 108 notches are provided to receive complementary locking members 110 and 112 respectively. Locking member 110 is formed with spaced upper and lower flanges 114 that are disposed in overlapped relation with corresponding areas of the side plates of the entering member 116 and are secured thereto preferably by welding. Likewise locking member 112 is provided with upper and lower flanges 118 that are similarly secured to the side plates of the receiving member 120,. The superposed upper and lower flanges of the locking member 112 serves as a stop for limiting the movement of the slider 26. The engaging portion 122 is similar in construction to the interlocking elements 18 and 20, whereas the engaging portion 124 is formed with two spaced iaws 126 and 128, the former being provided with a rounded recess, and the latter with a rounded projection between which the engaging portion 122 with its corresponding recess and projection is received. It will be obvious that disengagement of these interengaging portions can be effected only by an angular movement in a counter-clockwise direction.

It will be noted that in Figs. 1, 9 and 1'! that the corded edge of the tape on the entering or male side of the connecting parts has its terminusinside the upper cylindrical partof the connecting member, as indicated by dotted lines in each instance.

It will be obvious that the invention is not to be restricted to the precise constructions herein shown and described since many of the details, such as the structure of the stringers interlocking members and slider will necessarily vary or may be varied according to the particular uses for which the fastener is designed and the construction of the end attaching means of each stringer may also be varied by those skilled in the art, it

being intended that my invention be limited only by the scope of the claims.
