PADLOCK SLIDE FASTENER Filed April 25, 1946 INVENTOR JACK M. SCHAYE ATTORNEYS Patented Sept. 25, 1951 UNITED STATES PATENT I OFFICE PADLOCK SLIDE FASTENER Jack M. Sehaye, Brookl n, N. Y., assignor to Conmar Products Corporation, Newark, N. J., a corporation of New Jersey Application April 25, 1946, Serial No. 664,794

7 Claims.- (Cl. 70+-68l This invention relates to slide fasteners, and more particularly to slide fasteners arranged to be secured by means of a padlock.

The primary object of the present invention is to generally improve slide fasteners of the character specified. Heretofore, padlock slide fasteners have required a special modification of the article on which the fastener is used. This will be seen by inspection of the receptacles shown in a number of issued patents, for example, Schmidt l,759,283 and 1,759,284; Walrath 1,819,449; Legat 1,898,974; Rifkin 1,950,414; and Strayer 2,112,795. In these patents it will be seen that the slide fasteneris linear, there being a bottom end toward which the slider is moved to open the fastener, and a top end toward which the slider is moved to close the fastener, the said bottom and top ends being remote from one another. One object of the present invention is to provide a padlock slide fastener which is complete as fabricated and sold by the slide fastener manufacturer (except that the padlock may be supplied separately). The manufacturer of the envelope bag or handbag or the like merely sews the slide fastener into the article, much as is done with ordinary slide fasteners not having a padlock.

A further object of the present invention is to provide modified structures for fasteners used for widely different purposes, or made by different methods of manufacture.

To accomplish theforegoing general objects, and other more specific objects which will hereinafter appear, my invention resides in the slide fastener and locking elements, and their relation one to the other as are hereinafter more particularly described in the following specification. The specification is accompanied by a drawing, inwhich:

Fig. 1 is a fragmentary plan view showing one end of a slide fastener embodying features of my invention, with the pull in unlocked position;

Fig. 2 is a side elevationof thesame in locked condition;

Fig. 3 is a perspective View of .abridgeend stop which acts as a staple to receive the pull and the padlock;

Fig. 4 is a fragmentary plan view 'of a modified form of the invention using separable top stops, with the pull in unlocked position;

, Fig. 5 is a erspective view. showing the pull locked to the'top stops;

Fig. 6 is a perspective view of one of the top stops before it is attached to the tape;

Fig. '7 is a section through one of the top steps,

taken on the line 1-4 01 4-;

Fig. 8 is a fragmentary plan view of a modification of the invention using a single top stop formed of sheet metal;

Fig. 9 illustrates the blank used to make the stop shown in Fig. 8;

Fig. 10 is a perspective view of the stop;

Fig. 11 is a fragmentary plan view of a modification having a single molded top stop; and

Fig. 12 is an end view of the top stop.

Referring to the drawing, the invention in all its forms comprises generically a slide fastener the slider pull P of which is appropriately apertured to act as a h-asp fitting over a top stop having a staple S which is adapted to receive the shackle of a suitable lock L. The lock prevents lifting of the ull from the stop, and so prevents opening of the slide fastener. The fastener is complete as fabricated by the fastener manufacturer, and the manufacturer of the bag or other product using the fastener need merely sew the fastener into his product.

In the first form of the invention, shown in Figs. 1, 2 and 3, the top stop is of the bridge type, that is, it extends across and is secured to both tapes of the fastener. In Fig. 3 it will be seen that the stop takes the form of an inverted U-shaped projection 12, having jaws M at one end and jaws [6 at the other. shown in open position and the jaws 16 in closed position. The beaded edge I8 of tape 20 is clamped within the jaws l4, and the beaded edge .22 of tape 24 is clamped within the jaws I 6. The edges of the tape may be brought together above the bridge stop by suitable means, such as the stitching indicated at 26.

It will be seen that in the present case the upward projection l2 of the staple extends transversely of the longitudinal axis of the fastener, .and transversely of the plane of the tapes. The aperture 28 in the pull 3!] is dimensioned to fit over the projection 12, this being indicated in Fig.

.2 by the change from the broken line position 30 to the solid line position 30. The projection 12 together with the pull 30 extending across the open bottom of the same then define a closed aperture, through which the shackle 32 of padlock 34 may be passed.

Figs. 4 through 7 of the drawing illustrate a modification of the invention in which the upper ends of the tapes 36 and 38 are separable, in stead of being secured together by a bridge top stop. For this purpose, the beaded edges of tapes 36 and 38 each have a top stop, the general "nature of which will be clear from an inspection of Figs. 6 and '7. :Each stop has a projection .01 staple portion 40, with jaws 42 at its lower end.

The jaws M are As before, the projection extends transversely of the plane of the fastener tapes, but in this case it extends parallel to instead of transversely of the longitudinal axis of the fastener. The other tape has a similar projection or staple 44 (Fig. 4) with jaws 46'. When the projections 40 and 44 are brought into face to face relation, as is best shown in Fig. 5, the holes'therethrough register. The aperture 52 in pull 54 is dimensioned to fit over the projections, following which, the shackle 48 of lock 50 is passed through the holes in the stops.

It is not essential to employ two top stops, one being sufficient for the present purpose. A fastener employing such a stop is shown in Figs. 8, 9 and 10. In this case the top stop is formed of sheet metal. A blank is first stamped of approximately the shape shown in Fig. 9, this having open jaws 60 and 62 at the ends of a strip 64. The strip 64 is then bent to inverted U shape, as shown in Fig. 10. One set of jaws is shown open and the other closed, but it will be understood that they are both open until after application to the tape. In Fig. 8, the stop has been applied to the tape 66. The pull 68 is shown in open position, but may be swung to the broken line position 68, at which time it fits over the stop 64, which is then ready to receive the shackle 10 (shown in broken lines) of a conventional padlock (not shown).

In the modification shown in Figs. 11 and 12 the fastener again employs only a single stop, but in this case the stop is die cast instead of being formed of sheet metal. It comprises a projection or staple portion 12 having jaws 14 at its lower end. Here again the pull i6 is shown in solid lines in its open position, but when swung to the broken line position 16 it acts as a hasp fitting over the staple 12. The shackle T8 of a padlock is then passed through the hole 80 in the projection l2.

It is believed that the construction and operation of my improved padlock slide fastener, as well as the advantages thereof, will be apparent from the foregoing detailed description. The top stop of the fastener is used as a staple, and the pull of the slider is employed as a hasp which fits over the staple, following which the shackle of a padlock is passed through the staple. Thus the padlock slide fastener is complete as sold by the fastener manufacturer, and no special changes are needed in the article using the fastener. Precise adjustment of the location of the fastener relative to the bag or other article in which it is used is of no consequence, whereas in most prior padlock systems accurate location was important in order to provide for registration of parts of the fastener with eyelets or a staple or the like forming a part of the bag. The stop which is used as a staple may be of the bridge stop type, or may be separable. In the latter case either one or two stops may be used. The stops may be formed by stamping or coining opera- :tions, or by die casting or molding.

It will be understood that the sheet metal construction shown in Fig. 10 may be used for the double stop arrangement shown in Fig. 5, or with slight modification in design, may be used for the bridge stop shown in Fig. 3.

It will be apparent that while I have shown and described my invention in several preferred forms, changes may be made in the structures disclosed, without departing from the spirit of the invention as sought to be defined in the following claims. a

In the claims the term top stop is used, in

its conventional sense, that is, it means the stop at that end of the fastener toward which the slider is moved to interlock the fastener elements or close the fastener. The term is so used regardless of the position of the fastener.

I claim:
