FASTENING DEVICE Original Filed July 22. 1931 VIII/[m7 INVENT R Reissued Oct. 4, 1932 PATENT OFFICE JOHN A. H. SIERS, 0F JERSEY CITY, NEW JERSEY FASTENING DEVICE Original No. 1,859,751, dated May 24, 1932, Serial No. 552,314, filed July 22, 1931. Application for reissue filed June 30, 1932. Serial No. 620,211.

This invention relates to fastening devices for application to garments, luggage, containers and other analogous articles, and more particularly to devices of that general character which comprise two series of successively interlocking members adapted to be connected together. or separated by means of an operating member slidably coactin with the individual members or elements 0% each series.

It is one of the objects of the present invention to provide a fastener of this type of simple and inexpensive construction and which may be readily applied .to overlapping portions of the article which serve to flexibly connect the individual elements of each series with each other, said elements being so constructed and arranged, that when the fastener is closed, the interlocked series of elements together with the operating member therefor, are substantially wholly concealed by the overlappingportions of the article, so that the device will not objectionably affect the neat and attractive appearance of the latter.

It is another object of my invention to provide individual locking elements of novel and simple form having means with which the operating member will coact in a positive and reliable manner to interlock or disconnect the opposing elements, and which willalso coact with each other when in interlocked relation to positively prevent relative angular movement between either the adjacent members in the same series,- or the interlocked members in the opposing series.

For a detailed description of one form of my invention whichI at present deem preferable, reference may be had to the following specification and to the accompanying drawing forming a part thereof, in which Figure 1 is a plan view of, my improved separable fastener showing certain of the elements in the opposing series in interlocked relation and others separated from each other;

Fig. 2 is an enlarged horizontal sectional View;

Fig. 3 is a detailed perspective view of one of the female elements of the fastener;

Fig. 4 is a perspective view of one of the malev elements Fig. 5 is a transverse sectional view taken substantially on the line 55 of Fig. 2;

Fig. 6 is a sectional view taken on the line 66 of Fig. 2, and t Fig. 7 is a'plan view of a part of the operating member'for connecting and disconnecting the interlocking elements.

In the drawing, for clarity in illustration, I have shown the parts of my improved separable fastener on a greatly enlarged scale whereby-the details thereof may be readily understood.

Referring more specifically to the drawing, the overlapping parts of the article, such as strips of fabric or other similar material,

preferably in the form of tapes attachable to the article, are indicated at 1.. To the opposing sides of these fabric strips or tapes the two series of locking elements designated 2 and 3 are respectively fastened or secured. As indicated in Fig. 5' of the drawing, the flexible tapes may be stitched at their opposite longitudinal edges to the overlapping

edge portions

4 and 5 respectively of the gare ment or other article. This particular ap-Q plication of the tapes carrying the two series of fastener elements is of course merely suggestive, as the device might also be otherwise applied in its application and use in connection with other commercial articles.

Referring now more particularly to Fig. 3 of the drawing, the female fastener element is therein illustrated as preferably formed from a sheet metal strip terminating in the prongs 6 and 7 which are adapted to penetrate the tape 1' from one side thereof and be tightl clinched upon the opposite side of the tape.

t the inner ends of these prongs, the metal strip is doubled or folded on itself to provide the spaced projections or bases 8 and 9 for direct contact against one side of the tape 1. The central portion of the metal strip is likewise folded upon itself forming a lug or flat head and providing the projections or

flanges

10, 10 at opposite sides of the short slot or opening 11 which at one end thereof opens upon one lateral edge of said head.

It will thus be seen that the parts 8, 10 and 9, provide spaced pairs of confronting flanges, resulting in the formation of grooves or'channels on the opposite sides of the fas-.

11, as indicated at 12 The flanges orribs 10 and 10' provide spaced parts for cooperative engagement with spaced parts of the operating member or slide as will'be hereinafter more fully disclosed.

The male fastener element shown in Fig. 4 is also formed from a sheet metal strip having the attaching prongs '13 and 14 at lts ends.

' This strip likewise has the

foldedportions

15 and 16 forming spaced projections or bases for contact with one side of the other tape 1, and the additional'folded portions forming the flanges or projections 17 and 18 in spaced confronting relation to the

bases

15 and 16 respectively; Thus, it willbe understood that each female element likewise is thereby formed with the grooves or channels on its op pplsite sides.

e central portion of the metal strip from which the male element is formed is folded or doubled upon itself to provide a locking lug or head 19, said central portion of the strip being cutto produce the relatively narrow neck 20 connecting said head with the parts of the strip forming the flanges 17 and 18 respectively. These lockin heads are adapted to be received through t e slots or openings 11 in the female fastener elements.

As shown in Fig. 2 of the drawing, the two series of male and female elements are attached to the respective tapes 1 with the elements in each series arranged in close proximity but capable of a slight relative angular movement in the flexing of the tape when the male and female elements are in disconnected relation. This arrangement of the female elements, when said elements are in alignment with each other, results in the closure of the open ends of the slots 11 by the intermediate portion 21 of an adjacent element which constitutes the connection at the closed end of the slot therein between the flanges 10 and 10'. Thus, it will be understood thatafter the head 1970f a male locking element enters through the slot 11 of one female element, said element and an ad j acent female element at the opposite side of the neck 20cooperate with said locking head 7 to prevent its withdrawal from the slot or o ning. Therefore, as will be evident from 1g. 2 of the drawing, the heads 19 are closely confined-between the spaced portions 12 of the adjacent female elements, and a very close interfitting or interlocking relation of the elements in the two series is obtained.

v The operating slide for moving the opposing elements into and out of interlocking said slot.

relation preferably consists of two similar sheet metal parts, one of which is illustrated in Fig. 7 of the drawing. As shown, each of these parts, indicated by the numeral 22, has

the part 22 being flanged as more clearly.

shown in Fig. 5 of the drawing and thus providing the channel 23 and diverging

branch channels

24, 25 which are formed between said flanges and the spacing member ,26, disposed between the two parts of the slide and rigidly secured in connected relation with said parts by the rivets or pins indicated at 22'. One part of the slide member isalso provided at its wider end with a projection 27 to which the bar 28of a handle 29 is swiveled. This handle provides convenient means for the purpose of operating said slide member in either direction relative tothe two series of fastening elements. The'confronting portions or

flanges

8, 10 and 9, 10. of the female elements and the corresponding confronting,v

portions

15, 17 and 16,18 of the male elements form grooves in which'the opposing flanges on the parts of the operating member are slidably enga ed.

rom the above, it will be understood from reference to Fig. 2 of the drawing, that in closing the fastener or interlocking the two series of fastening elements, the operating slide is moved upwardly, and as the flanges of said locking elements move from the

diverging channel branches

24, 25 into the channel 23 ofsaid slide, the heads 19 of the male looking elements are successively caused to pass through the slots 11 of the female elements, such interlocking action being effected, while the adjacent slotted female elements are disposed at an angle to each other,

as indicated at 30 in Fig. 2 of the drawing. In the continued movement of the operating slide, and when the flanges of the fastening elements are enga ed in the straight channel portion 23 thereo said adjacentfemale'elements are brought into alignment with each other at opposite sides of the neck 20 of a male fastening element, thus effectively closing the open end of the slot 11 in one of said elements and together cooperating with the head. 19 to revent its Withdrawal through t will be evident that when the movement of the operating slide is reversed, a reverse action occurs and the opposing elements in the two series are successively disconnected from each other. i i

From reference to "Fig. 5 of the drawing, it will be noted that the parts 22 of the slidable operating member are wholly positioned fore, when the fastener is closed, the interlocked fastening elements together with the slide and its operating handle 29 will be entirely, concealed so that practically none of the metal parts will be visible. It will furter be noted that when the fastener is closed,

the flanges or

projections

10 and 10 of they the device is obviously susceptible of embodiment in various other alternative structures, and may be otherwise applied and used for a great variety of diiferent purposes. Accordingly, I reserve the privilege of resorting to all such legitimate changes therein, as may be fairly incorporated within the spirit and sco e of the appended claims.
