SEPARABLE Application filed Deceinber 22, 1927, Serial No.
This invention relates to separable fasten ers of the type in which two flexible stringers are adapted to be connected and disconnected by a plurality of interlocking jaw or other fastener members cooperating with a sliding cam device mounted upon both members.
The object of the present invention is to devise improved means for rendering the two stringers completely separable instead of being permanently attached to one another asis generally the case. p
The invention consists in a fastener of the type referred to having novel separable connecting members at one end formed so that a toot or projection upon one member engages a correspondingly shaped recess or notch in the other member, so that when said members are enclosed within the slider cam, the stringer to which one of them is fastened is movable longitudinally in relation to the cam and to the other stringer on which such cam device remains, to permit either of the complete separation of the stringers or of the proper positioning thereof to enable thev slider to function in the usual manner for locking and unlocking the fastener.'
The invention also consists in a fastener according to the preceding paragraph in which the separable connecting members are formed so that relative longitudinal move, ment in one direction is prevented while lat eral separation is readily permitted when the connecting members are spread apart by the slider.
The invention also consists in the forms of fastener member hereinafter described or indi ated. I
he accompanying drawings illustrate two modes of carrying out the invention.
Figure 1 is an elevation of one form of separable fastener in accordance with the invention.
Figure 2 is a similar view showing the parts completelyseparated and I v Figures 3 and 4 are plan views respec tively of Figures land 2.

convenient manner I form the fastener with 12261 of 1915) and the usual or any desired form of slider cam device 0 having divergin channels also provided in association with such stringers, there bein if necessary or desirable a pull device d to facilitate manipulation of the slider cam. At that end of the fastener which is usually permanently closed a flat rectangular or other suitably shaped metal attachment is secured to each stringer, one of these attachments e having at that edge adjacent to the other stringer a trian gular shaped notch e the side of which nearest'the' chain of interlocking members is substantially at right angles to the edge, while the other side may inclineat a suitable angle (say, about 15 or 20) to the edge. The other attachment 6 is provided with a correspondingly shaped triangular projection ewhich is furnished with a projecting tongue e" extending in a direction away from the chain. The thickness and combined width of these attachments or connecting members when engaged with one another are such that the over-all dimensions correspond with the dimensions of the interlocking chain members when engaged (as shown in Figure 1) so that the slider cam devices can slide over the attachments and spread them apart until stopped in the manner hereinafter described.
Attached tothe stringer a carrying the notched fitting e is another rectangular or other suitably shaped plate or stop member flying in a plane at right angles to the above 7 tongue e of the attachment e on the other.
' The plate f is preferably provided with an in tegral flat portion) which is riveted to the i such diameter as will admit the corded edge of the tape at one side and the projecting stringer a and holds the plate firmly on the stringer as shown in Fig. 1.
When closing the fastener the sliding cam c which remains on the stringer a as shown in Figure 2, is moved along the stringer until it comes into contact with the slotted plate 7, whereupon the'tape of the other stringer a is. pulled in a downward direction, as viewed in the drawings, through the channels in the sliding cam and slotted plate f until the tongue 6 enters the circular portion of the slot '7. If now the slider is moved away from these attachments the triangular projection e engages the corresponding notch 0 thus bringing the two stringers into correct relative position for the interlocking chain members to engage and on continuing the movement of the slider such chain members will interlock in the usual manner. A complete separation of the stringers may be accomplished by a reversal of the operations described above.
Figures 5 to 8 represent a slightly modified form of fastener in accordance with the in vention and similar parts in the two sets of views are denoted by similar reference characters. In this modification, however, the separate plate fitting f is omitted and is replaced by a projecting part of the fitting e in a circular aperture in which engages the pro ection a, while there is also provided in this form of fastening a guiding tongue or member 9 upon the completely removable stringer, such member facilitating the entry of the stringer into its proper position for the closing of the fastener by the slider cam and permitting of ready manipulation of such stringer when connecting or disconnecting the same.
It will be understood that the invention is not to be limited to the foregoing details of construction which are given purely by way of illustration since I may arrange the notched or recessed member on either of the stringers with the tongued or like member upon the other, and I may vary the shape of such members and the means by which they are made to engage with one another depending upon the type or construction of fastener to which the invention is to be applied or any ractical requirements that may have to be ulfilled. 1
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a fastener adapted to be completely separated at both ends, a air of stringers having cooperating interloc ing members on their adjacent edges, a slider having diverging channels movable along said stringers to engage and disengage said members, separable connectin members adjacent corresponding ends 0% said stringers adapted to pass into the channels of said slider to be' having cooperatin spread apart thereby, cooperating angular notches and projections on the adjacent edges of said connecting members adapted when engaged to prevent longitudinal separation thereof, a stop member adjacent the end of one stringer to retain the slider on that stringer, a longitudinal recess in said stop member, and a longitudinal projection adjacent the end of the other stringer insertable into said recess to prevent lateral separation and to position said interlocking members for engagement in the proper order, whereby said last mentioned stringer may be drawn lengthwise through said slider to effect complete separation of the stringers when said connecting members are spread apart.
2. In a fastener adapted to be completely separated atlboth ends, a pair of stringers having edgewise interlocking members, a slider movable along said stringers to engage and disengage said members, separable connecting members adjacent corresponding ends of said stringers adapted to enter said slider, a stop member fastened to one stringer beyond its connecting member to retain the slider on that stringer, and a slotin said stop member adapted to receive the edge of the opposite stringer to prevent edgewise separation of the stringers and to permit said opposite stringer to be drawn lengthwise through said slot and said slider when said interlockin members are disengaged.
3. In a fastener adapted to be completely separated at both ends, a pair of stringers having corded edges supporting cooperating interlocking members,a slider movable along said stringers to engage and disengage said members, separable connecting members adjacent corres onding ends of said stringers adapted to reely enter said slider, a stop member fastened to one stringer beyond its connecting member to retain the slider on that stringer, a. slot in said stop member shaped to receive the corded ed e of the opposlte stringer when inserte lengthwise therethrough, and a projectin tongue on said opposite stringer insertab e lengthwise into said slot to prevent edgewise separation of the stringers.
Y 4. In a fastener adapted to be completely separated at both ends, a pair of strin ers interlockin mem ers on their adjacent e ges, a slider aving di- I verging channels movable along said stringers to engage and disengage said members, separable connecting members adjacent corresponding ends of said stringers adapted to pass into the channels of sa1d slider to be spread apart thereby, said connecting members havm transversely flat contacting faces, one 0 said' connecting members having a recess and the other of said connecting members havin a coo erating projection on its contactlng ace a apted when said connecting members are engaged to prevent relative longitudinal movement of said connect ing members and to guide said interlocking members into position for en agement in the proper order, a stop mem er adjacent oneof said connecting members to retain the slider on that stringer when the connecting members are disengaged, a longitudinal recess in said stop member, a longitudinal projection formed adjacent the end of the other connecting member and insertable into said recess to prevent lateral separation of said connecting members, and to position said interlocking members for engagement in the proper order, whereby said connecting member having the longitudinal projection may be drawn lengthwise through the slider to efl'ect complete separation of said stringers when said connecting members are spread apart.
In testimony whereof I have signed my name to this specification.
