In one instance, assembly of the two members. The direct result I accomplish the objects of my invention by the of this distinguishing feature of my invention is means and methods set forth in thefollowing the material reduction or substantial elimination of hinginess" of such separable bottom-stops along their axis of connection, whereby localized piercing strains, to which the adjacent interlocked teeth of the slide fastener are frequently subjected, are more safely withstood. In the case of the "hingey" separable stop constructions of th'e prior art, a localized piercing strain upon, say, the first half dozen teeth, may easily ".pop these teeth apart, necessitating a difficult reassociation of the disengaged tooth elements. With my relativelyrigid bottom-stop construction, the adjacent interlocked fastener elements or teeth are, in a sense, reinforced or protected against such strains, and inadvertent dissociation of the fastening at this point is substantially precluded.

The male and female elements which, when assembled, constitute my improved separable bottom-stop for slide fasteners are also individually distinguished from corresponding prior art elements. The female member of my construction consists of one piece of metal or the like which is folded along the end edge of its associated iiexble Stringer to form stringerclamping wing portions. These wing portions are provided with lateral extensions formed into a split, pin-receptive socket disposed at the 1ongitudinal or fastening edge of the Stringer. Since the side edges of said wing portions are inherently unattached, the split or slotted socket may be die-formed without a slot-cutting operation. Though formed in the open side of the blank, my slotted socket 1s, nevertheless, sufficiently sturdy to resist spreading, due to the provision of unique clamping tongues integral with a wing portion of the female member, wh'ch tongues are curled about the longitudinal edge of the associated stringer clamping said wing portions together, adjacent each end of the socket. The clamping tongues mentioned also have utility in their relationship with the pin portion of the male member in that the lower clamping tongue serves as a cam which urges the lower end of the pin of the male member laterally outwardly as it approaches nal assembly with the female member, thus canting the pin in the socket and bringing the adjoining terminal portions of the stringers into substantial parallelism and closure.

The male member o f my preferred construction herein illustrated is also individually novel in that secure assembly thereof with the tape or stringer is possible without piercing the tape. In accordance with a concept of.. my invention, the tape is clamped upon the tape by laterally extending wing portions having the tubular longitudnal pin as their common fold, maintenance of clamped relationship being effected by a wide tongue integral with one of said wing portions and crimped over upon the other wing portion along the end edge of the associated tape or stringer. Preferably, and more specifically, the end of the tape is extended and folded back upon one wing member so that the extension of the tape is clamped between the outer surface of said wing member and the crimped tongue. The security afforded by such anassociatlon of male member with tape is unexcelled by any method of the prior art.

More specifically, and with reference to the accompanying drawing, my invention is preferably embodied in a separable bottom-stop for slide fasteners consisting of one-piece male and female members "A and B, respectively. These members are adapted to beu associated in a common plane. as shown in wigs. l, 2 and 3,

by longitudinal insertion of the pin I0 of the male member into the socket II of the female member. The socket of the female member is enlarged at its portion Il to facilitate such insertion, but the lower portion IIb thereof is of 5 a size such as to contact the fully seated pin III more snugly, due to opposing contact of the lower end of the pin with another portion of the member B, other functions of which are later to be described. l0

The female member B of the structure is formed from a single sheet of metallic or equivalent material and includes a pair of wing portions I2 and I3 formed by folding of the blank along the line :r which corresponds, generally, 15

to the end edge of thestringer I4 with which the female member is to be associated. The folded portion of the member is extended laterally beyond the longitudinal edge of the stringer I4 to constitute a pin stop I5. Each of the wing portions I2 and I3 is provided with laterally extending portions which are shaped to constitute the socket II previously described. This socket II is, being formed from extensions of the sides of the wing portions I2 and I3, open or slotted in character. The wing portions I2 and I3 are clamped flatly upon opposite faces of the Stringer I4, and such clamped relationship is maintained by tongue portions I6 and I 1 integral with the wing portion I2. The tongue portion I6 is curled about the longitudinal edge of the Stringer Iland bears upon the Wing portion I3 adjacent the smaller end of the socket II. The tongue portion I1 is similarly curled about the longitudinal edge of the strnger I4 and serves to clamp down a small lug I8 which is formed as a part of the Wing portion I3 adjacent the socket thereof. Preferably, the lug I8 is of lesser thickness than the normal thickness of the wing portion I3, whereby the tongue I1 lies substantially even with the wing portion I3 of the finished article. Where the construction is adapted for use with stringers of the tape type provided with a beaded edge for the reception of interlocking fastener elements, the wing portions I3 and I4 are, at their line of association with said beaded edge, died into slightly tubular form. In such a construction, the lug I8 is, in a sense, a thin extension of the tubular portion of the wing portion I3, and thetongue I1 clipped upon said extension I3 has the appearance of a continuation of the tubular portion of the wing portion I3. It will be appreciated that, in the construction just described, the portion of the Stringer I4 which is interposed between the wing portions I2 and I3 provides a definite spacing therebetween, and the tongues I6-and I1v which clampthe wings 'I2 and I3 prevent spreading thereof and insure maintenance of size in the socket II. The slots IIc and IId of the socket are inherent in the structure described, and a definite width for these slots may be readily established bythe dies which are employed for the forming of the blank, consideration being given to the thickness of the stringer with which the structure is to be assembled.

The male member A of the construction illustrated is also formed from a single piece of sheet stock by suitable dieing operations. As distinguished from the female member, the wing portions I 9 and 20 of the male member are joined by a common fold which lies along the longitudinal. commonly beaded edge of the Stringer with which it is to be assembled. This common fold takes the form of a tubular pin portion 2i formed about the beaded edge of the strnger and closed at its outer end. The stringer- 22 which carries the male member is interposed between the wing portions I9 and 20 and is preferably extended over and folded back upon the wing portion 20 for a short distance, as shown. Upon this folded-back portionv 22a of the Stringer, a Wide tongue 23, integral with the end of the wing portion I9, is clamped. There is thus effected not only a clamping of the wing portions I9 and 20 upon the main body of the tape 22, but a clamping of the extension of the tape 22 between the wing portion 20 and the tongue 23. Obviously, as shown in Fig. l, the portion 22a of the tape is trimmed back slightly from the pin portion 2|, in order to avoid interference with assembly of the pin 2I and the socket II. Limitation of the extent of insertion of pin with socket is assured by the abutment of the closed end of the pin 2| with the stop I5 of the female member.

Apart from the novelty of the male and female members, considered individually, the

structure disclosed in the drawing is characterized by a novel keyed relationship of male and female member, whereby hinge action between these members is substantially precluded, as distinguished from all prior art constructions for the same general purpose. Specifically, vthis elimination of hinginess is obtained by -a keyingv of the male member in the diametrically op-` posed slots provided at opposite sides of the pin axis of the socket II. The slot or key-way IId of the socket is formed with a definite width corresponding to, or slightly lessthan, the thickness of the male member along a line just inward of the pin portion proper 2|. As a result, inser- 'tion of the pin 2| into the socket II is characterized by a light frictional contact of the walls defining the slot IId with the pin-adjacent surfaces of the wings I9 and 20 of the male member. A slight variation in size and thickness is Acharacteristic of all small sheet metal articles formed by die-shaping operations. Hence, the fit of the tubular pin portion 2| with the portion IIb of the socketcannot be relied upon to insure complete elimination of a tendency toward hinging afforded solely by the fit of the Wing portions I9 and 20 with the socket slot IId. Accordingly, I have provided additional key means which, in co-operation with the key and slot arrangement just described, precludes hinge action between pin and socket to such an effective extent as to eliminate a large-portionof the strain otherwise frequently exerted upon the immediately adjacent interlocking fastener elements commonly mounted upon the beaded edges of the tapes I4 and 22. This supplementary or co` operative key means comprises a key portion 24 embossed out of or otherwise provided upon the pin portion 2| of the male member. This key portion 24 is, in the embodiment disclosed, diametrically opposed with respect to the wing portions I9 and 20 of the male member and is of a width corresponding to the width of the socket slot II. The socket II of the female member is provided with an enlarged portion IIB, as 'ha-s been explained. Thurs, as is conventional and desirable, the pin portion 2| of the male mem' ber may be longitudinally inserted into the socket II at an acute angle with respect to the true axis thereof. Because of this ability for initial linsertion at an acute angle, the pin key 24 encounters no interference from the curled tongue Ilof the female member. However, as the upper end of the key 24 clears the tongue I1 and enters the socket, the lower or closed end of the pin 2| encounters the tongue I6 of the female member, urging said closed end laterally outwardly against the reduced portion IIb of the socket. This laterally outward movement of the lower end of the male member effects lateral inward movement of the upper portion of the male member such as to induce engagement of the key 24 within the slot IIc of the socket.` Thus engaged, the relatively abrupt terminus of the key 24 precludes material retraction of the pin from the socket, due to the function of the curled tongue I 'I as a stop for the key 24. AIn actual manufacturing practice, it has been found desirable to adjust the tongues I6 and II laterally with respect to the socket axis. This may be accomplished either in the actual operation of curling these tongues about the beaded edge of the associated Stringer, or by a subsequent flattening pressure or blow administered to the tongues after they have been so curled. The

proper disposition of the tongue I6 with respect 1 bring the upper portion of the pin 2| into close relation with the curled tongue II. The tongue I'I may, if desired, be flattened slightly, after its curled disposition upon the boss I8 and the beaded edge of the tape 22.

The operation of the construction illustrated should be clear from the foregoing description. The male and female members are tightly clamped upon -their respective tapes by the wing portions I9, 20,', and I2, I3, respectively, due to the effectiveness of the tongues Z3 and I6, I'I, respectively. In practice, the width of the socket slot IId is proportioned to the thickness of the male member assembled with its Stringer. Likewise, the key 24, embossed outwardly from the pin portion 2| of the male member, is of a. width corresponding to the width of the inner socket slot IIC. Substantially complete elimination of hinginess along the pin axis is thus assured. Guidance of the pin into proper keyed relationship with the socket is Iassured through thesupplemental function of the lower tongue I6 as a cam surface coactive with the lower end of the pin during the final portion of the insertive movement of the pin into abutment with the stop I5. The stop I5, as is conventional in this art, assures proper alinement of the usual interlocking fastening elements Y and Z carried by the respective beaded edges of the `Stringer tapes 'means by which the male and female -members are secured to their respective stringers is not essential to the' realization of the keyed association of male and female members. For example, it is obvious that the tape might be clamped entirely between the wing portions I 9 and 20 of the male member. While the tongues I6 and I1 of the female member are formed as extensionsv of its wing portion I2 and serve, not only to clamp the wings I2 and I3 of that member into securement with the interposed tape I4, but serve also as a cam and stop for the pin 2| and its key 23, these functions might be individually accomplished by distinct instrumentalities, without departing from the basic principles of my invention. Further changes and variations should be obvious to those skilled in the art. Accordingly, I claim my invention broadly, as indicated by the appended claims.
