END STOP FOR SEPARABLE FASTENERS Original Filed Feb. 29, 1936 ATTORNE;

Patented Sept. 5, 1939 PATENT OFFICE END STOP FOR 'ISEPARABLE FASTENERS Davis Marinsky, Bronx, N. Y., assignon to Whitehall Patents.0orporation, New York, N. Y., a corporation. of New York Original application February 29, 1936, Serial No. 66,341. Divided and this application May 15, 1937, Serial No. 142,746

5 Claims. (Cl. 24-205) This invention relates to what are known as end stops and especially detachably coupled end stops for separable fasteners, and the object of the invention is to provide a simple and economical method of constructing and assembling devices of the class described to form a strong and durable detachable end stop which is also simple in the structure of the parts and in the method of coupling and uncoupling the same; a further object being to provide detachable end stops, the several parts of which have relatively long bearing or engaging surfaces on the tapes or stringers, and further wherein the separate parts are interlocked with each other to prevent relative movement of the parts; a further object being to provide an end stop consisting of preformed parts which may be formed from stampings or die castings and which when assembled will be interlocked one with the other and which includes means in addition to the mounting plates for retaining the parts against displacement from the tapes or stringers; and with these and other objects in view, the invention consists in an end stop of the class and for the purpose specified, which is constructed in parts and in assemblage in accordance with the method hereinafter more fully described and claimed.

This invention constitutes a division of my prior application Serial No. 66,341 filed February 29, 1936, and is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views,

and in which:

Fig. 1 is an enlarged detail view of one end portion of a separable fastener showing one of my improved end stops mounted in connection therewith.

Fig. 2 is a view showing a part of the structure shown in Fig. 1 with parts in section.

Fig. 3 is a perspective view of one of the mounting plates which I employ, detached.

Fig. 4 is a view similar to Fig. 3 indicating a plate partially secured to one end of a tape or stringer.

Fig. 5 is a view similar to Fig. 4 showing the plate secured to the tape.

Fig. 6 shows perspective View of two channeled coupling bars which I employ, illustrating the form thereof prior to attachment to the stringers.

Fig. 7 showsthe bars attached to two stringers l5 and the coupling plates secured to the stringers.

Fig. 8 is a perspective view of a yoke-shaped coupling block or housing which I employ; and

Fig. 9 shows the block or housing attached to one of the stringers or the bar and plate attached to the stringer.

In Figs. 1 and 2 of the drawing, I have shown for the purpose of illustrating one use of my invention one end portion of the tapes Ill and II of a separable fastener, to the beaded edges Ilia, 2

Ha, of which are secured the coupling links i 2. The links are interlocked and separated in the use of the fastener by a slider I3 movable longitudinally of the fastener stringers in coupling and uncoupling said links. The slider has top and bottom plates joined by a V-shaped body I4 at the enlarged end portion of the slider as in other devices of this kind, which body l4 also forms the diverging channels through which the separated links 62 pass. At Ha. I have shown the reduced end portion of the slider having the single channel into which the diverging channels extend as in other sliders of this class.

In Figs. 1 and 2 of the drawing, I have also shown at i5 a detachably coupled end stop device, by means of which the end portions of the tapes ill, i i, may be detached one from the other to permit the separation of the garment or other parts to which the fastener device is secured in the use of devices of this kind on such garments as jackets, wind-breakers and the like or in any other uses where it is desirable to separate the two stringers of the fastener for any purpose whatever. The end stop device l5 consists of two substantially similar mounting or coupling plates l6, iiia, two substantially similar coupling bars 57, Ha and a coupling block or housing l8. In constructing the end stop device I5, the parts it, II and N are separately formed and are then assembled in the manner hereinafter described.

Each of the parts 16, Isa is of the same general construction and these parts are simply formed lefts and rights to adapt their mounting to the stringers l and ii, and the brief description of one plate will apply to both. In Figs. 3, 4 and of the drawing, I have shown the plate i6 and have indicated the manner of attaching the same to the tape i0. As shown, the plate i6 is preferably formed from a sheet metal blank which is cut out to form side plate portions I9 and 20 having apertures 2! adapted to register with each other. When the plate i6 is secured to thesupport i0 as shown in Fig. 5, one side edge of the side plate i9 is provided with a flange 22 and the other side edge with a prong 23 and the curved wall 24 which joins the plates I9 and 20 is cut out as seen at 25 to form a key receiving portion as later described.

After the plates I6, I6a have been formed and shaped in the manner illustrated in Fig. 3 of the drawing, the trimmed end portion of the tapes is placed upon the inner surface of the plate I9 with the prong 23 passing upwardly through the tape as may be seen in Fig. 4 of the drawing, after which the plate 20 is then folded downwardly upon the tape I0, and the flange 22 and prong 23 are folded inwardly upon the plate 20 in the manner shown in Fig. 5 of the drawing, it being understood that the curved wall 24 joining the plates I9 and 20 extends around the 26 on one bar I! and the provision of a recess or aperture 21 on the bar I'Ia, note Fig. 2 of the drawing, the two bars I'I, I'Ia are. of the same construction and are each provided with a longitudinal channel 28 to receive the beaded edge of the stringers. The channeled structure forms side walls 29 and 38 and the surfaces of the channel 28 are provided with logitudirially spaced ribs 3| arranged at one end portion of the bar which are adapted to engage the fabric of the tapes I0, II to aid in retaining the bars I'I, I'Ia against longitudinal movement upon the stringers, and in like manner, to aid in securing the attaching plates IS, Ilia to the stringersthrough the interlocking engagement of the bars with the plates by reason of the inwardly projecting members 32 engaging the cut out or recess portions 25 of the plates I6, Ilia as is indicated in Fig. 2 of the drawing in the coupling of the bar Ila with the plate I641.

The bars H and Ila are die cast in the manner shown in Fig. 6 of the drawing or with the walls 29 and so separated so as to facilitate the mounting of the bars upon the plates I6, Ilia and the stringers Iii and II. After placing the bars in position thereon to bring the projections 32 into registering alinement with the recesses 25, the bars are compressed upon the plates and tapes in the manner shown in Fig. 7 to securely couple the parts together and to the tapes III and II. The inner adjacent surfaces of the bars I1, I'Ia are straight and preferably beveled to a slight degree at one end thereof as indicated at 33 to facilitate the coupling and uncoupling of the bar I! with the housing I8 in attaching and detaching the stringers.

It is preferred that the channeled bars or rods N, Na be formed from die castings so as to econ omize and simplify the production thereof, it being understood that the castings will be formed in the general contour or arrangement shown in Fig. 6 'of the drawing and may be secured in position by the application of pressure to bring the opposed walls 29 and 38 into firm engagement with the adjacent surfaces in connection with which the bars are coupled. In this connection, it is also preferred that the coupling block or housing I8 of the device be formed from a die cast material in order to simplify and economize the production of this part.

The block I8 consists of an elongated yokefor use.

shaped body, the side walls 34 and 35 of which have rounded outer surfaces and the side edges of these walls terminate in inwardly extending flanges 36 which are spaced apart to form channels 31 to receive the plates I6, Ilia. The crosshead 38 of the block I8 joins the side plates 34 and 35. The inner surface 39 of the crosshead 38 serves as a stop wall lirriiting inward movement of the bar I1 as is indicated in Fig. 2 of the drawing. The block I8 is secured to the bar Ila only; the bar I! and the associated parts being attachable and detachable with respect to the block. The walls 34, 35 of the block I8 as formed are slightly diverged, and the block I8 is slid onto the bar IIa over the end of the tape II; and when moved into its innermost position, the walls 34 and 35 are compressed upon the plate Ilia and bar Ila, and a hole 40 is drilled or otherwise formed through the walls 34, 35 of the block I8, through the bar Ila, and through the plate Mia and the tape II, and a rivet or coupling pin 4|, note Figs. 1 and 2, is then passed through the several parts and riveted over to secure said parts together and to firmly couple the block I8 to its associated parts. The side flanges 31 are arranged directly upon the outer edges of the walls 29 and 30 and inwardly of the flange 22, and the inner adjacent surfaces of the walls 34 and 35 rest upon the upper and lower surfaces of the bar IIa.

In practice, the bar I! will be made slightly smaller in its dimensions to permit free movement of said bar into and out of the channel which is indicated at 42 in Fig. 9 of the drawing and which is formed within the block I8 at one side of the bar I'Ia and the flanges 31 to the left of the block I8 as shown in Fig. 9. These flanges serve to engage the outer edges of the walls 29 and 30 of the bar I! to securely retain this bar against displacement from the block I8 when the parts are secured together in the manner clearly seen in Figs. 1 and 2 of the drawing. It will also be noted that each bar I'l-lla is of substantial thickness and therefore that the edges of the walls 29 and 30 .form pronounced shoulders for engagement with the flanges 36; The several parts of the detachably coupled end stop I5 may be plated or otherwise treated to give the same the desired finish and appearance consistent with that of the appearance of the links I2 employed on the stringers.

With the several parts of the device I5 assembled in the manner or in accordance with the method above defined, the device is then ready In coupling the detachable parts of the device, the slider I 3 is first brought into the position shown in Fig. 2 of the drawing and the bar I1 is then passed through the slider and into the channel 42 and moved into the position shown in Fig. 2, in which position, the projecting tongue 26 enters the recess 21, after which the slider I3 is moved outwardly in-the manner partially illustrated in'Fig. lof the drawing in the operation of coupling the stringers together. Thus, when the separate parts of the fastener are coupled together as shown in Fig. 1, the detachably coupled ends of the stringers will be securely retained against displacement or detachment as long as the links I2 remain coupled together. In this connection, it will of course be understood that the bars or rods 11, Ila project beyond the inner end of the coupling block I8, and the reduced end I3a of the slider is adapted to extend onto said projecting ends of said bars when it is demoving the slider into this position which is shown in Fig. 2 of the drawing, the bar l'I may be withdrawn from the block l8 through the slider l3, thus permitting the separation of the stringers l0 and II one from the other.

The projecting tongue 26, in addition to aiding in securing the bars ll, Ila against-relative movement when coupled together, also provide means for preventing movement of the slider I3 in the operation of closing the fastener until the tongue 26 has entered the recess 21. When the tongue is in proper position, the operation of coupling the stringers may be performed without danger of slippage or movement of the bar I I and its associated stringer with respect to the companion bar Ila and the housing I8 thereof, thus facilitating the coupling of the fastener stringers.

The separate pairs of parts i6, [6a, l1, Ha and I8 will be performed by the tools, dies or other means provided for the construction thereof, and these parts will be mounted or assembled upon the stringer tapes in a successive series of operations in the manner above defined. By constructing the separate parts in the manner disclosed, a very simple and yet, a very positive means is provided for securing the parts to the stringer tapes in such a way as to eliminate as much as possible the stresses and strains to which the parts are subjected, and to avoid the possibility of detachment of the parts from the stringer tapes when excessively strained. The projections 3i aid materially in this reinforcement of the mounting upon the tape and extend the engaging or gripping area of the parts to a large degree over the surface of the tapes including the beaded edges thereof.

The apertures 2! are provided for certain reinforced mountings to garments or other articles in connection with which the fasteners are employed for example eyelets may be passed through the apertures in attaching the fasteners to garment parts or other supports; and when such mountings or attachments are not essential, the plates l6, lfia may be materially reduced in size, or in fact, may be confined to portions engaging the beaded edge portions of the mountings tapes. In some uses of the invention where the stress or strain upon the end stops is relatively light, the mounting plates or their equivalent may be dispensed with entirely and the bars H and Na alone employed directly upon the tapes, the same being shaped or characterized to fit the tapes. In this connection, it will be understood that the channels 28 of the bars ll, l'la are fashioned to conform with and fit snugly upon the tam and the plates it, Hid, as indicated in Fig. 2 of the drawing. The illustrations in the accompany drawing are all enlarged and exaggerated as to size in order to more clearly illustrate the details of construction.

When the slider is moved upon the projecting ends of the bars 51, Ha, the transverse V- shaped portion Id of the slider in separating the end links also serves to unlock the bar I! so as to move the projecting tongue 26 out of the recess or aperture 21, permitting the free release of the bar I! and its associated stringer in the separation of the stringer. At the same time, this position of the parts facilitates the free insertion of the bar I? into the position shown in Fig. 2 and in moving the slider l3 into the position shown in Fig. 1 the projecting end portion of the bar I! is moved in the direction of the bar Ila and the projecting tongue 26 into the recess or aperture 21.
