Patented Nov. 1, 1932 J OHN'A. H. SIERS, OF JERSEY CITY, NEW JERSEY TERMINAL FASTENING DEVICE Application filed December 10, 1931. Serial No. 580,010.

This invention relates to fastening devices capable of being applied to the margins or connecting portions of garments, luggage, etc., and comprising a series of successive interlocking members adapted to be brought together or separated by means of a slidable member which manipulates the interlocking parts in the required'manner.

The subject-matter of this application is w to provide certain additional features such that the slidable fastening device described and claimed in my prior application Serial No. 552,314, filed July 22, 1931, may be used in connection with garments, luggage or other coverings or containers where the edges of the same are to be entirely disconnected and separated from each other, so as to provide an unobstructed opening.

The object of this invention is, therefore,

2 to provide means whereby the adjacent edges which are connected by the slidable fastening devices described in my prior application may be provided with a terminal connecting device which, when the slider has reachedthe end of its travel, will permit detachment and separation of the corresponding ends of the slidable fastening device, and also permit their easy connection when the edges are to be fastened together. The improvement will primarily allow the slider to engage the fastening devices in the correct way after the ends of the edges of the material have been brought together. Thereafter the longitudinal motion of the slider will cause the fastening devices to engage each other successively in the proper manner along the entire edges of the material, thereby causing the same to be fastened together.

For a detailed description of one form of my invention which I at present deem preferable, reference may be had to the following specification and to the accompanying drawing forming a part thereof, in which Fig. l is a plan view, partly in section, showing my improved terminal fastening device in position, one-half only of the slider being shown.

Fig. 2 is a plan view of the lower end thereof, as shown in Fi 1, but showing the end to of the complete sli er.

Fig. 3 is a perspective view of one member of the terminal fastening device.

Fig. 4 is a perspective view of the opposite member of the terminal fastening device.

Fig. 5 is a plan view of the slider, and

Fig. 6 is an end view of the same.

Referring to the drawing, it will be seen that the numeral 1 indicates a suitable strip of fabric or other material, preferably in the form of a tape, on which the interlocking elements 2 and 3 are mounted or fastened. The general shape and action of these fastening devices are preferably substantially in accordance with the detailed description thereof set forth in my prior application, above mentioned.

In Fig. 1, two pairs of such interlocking elements are shown as being carried by the fabric. Below said pairs, the successive memhere are similar to the interlocking members, but are not provided with projections or slots, as they are more in the nature of spacing elements 4:, which serve to determine the position of the lower terminal fastening member 5 and its complementary fastening member 6. The spacing elements 4 are shown to be without interlocking parts, in order that the edges of the material to which the fasteners are attached may be moved relative to each other and separated, as will be hereinafter described.

One portion, or the hooking member 5, of the terminal fastening device, is illustrated in Fig. 3. This comprises a portion adapted to be connected with the fabric, as are the other members of the fastening device, that is, through the use of tapering or projecting prongs 7. The opposite side of said terminal fastening member is provided with two hooks, having reversely bent outer portions as indicated at 8, in Fig. 3.

The opposite member 6, .of the terminal fastening device, is similar to that just described, except that it is provided with no hooks. It is made slightly longer than the spacing elements 4, and is provided with two sets of prongs 9. Both of these members are provided with grooves similar to those of the interlocking members 2 and 3, as indicated in the drawing. The slidable device which causes the members to interlock and is usually termed the slider is illustrated in Fig. 5, and consists of two similar or correspondingly shaped parts 10 and 11, which are held together by suitable pins, as indicated at 12, which pins pass through slightly raised bosses 13 that serve to separate the flanged parts of the slider the required distance. As described in my prior application, this slider includes a grooved portion, the upper end of which branches into separate grooves which are formed by the centrally raised triangular projection and by the flanged margins on the opposite sides 10 and 11; One portion of this member is also provided with a cylindrical part 14, through which a bar 15 of the handle 16 may be passed.

Referring now to Fig. 1, it will be seen that when the member 5 carrying the books 8 is attached to the fabric 1, the upwardly projecting part of the hooks will be adapted to engage the grooves of the complementary terminal fastening member 6. \Vhen the slider is pushed downward to disengage the interlocking elements of the fastener, the flanges on its lower end will contact with the ends of the hooks 8, which will stop its downward motion as indicated in Fig. 1. The interlocking members having been separated by the terminal portions and spacing elements, the left-hand strip of fabric 1 with the various members carried thereon may then be slid upward so that the hooks 8 are disengaged from the slots in the terminal fastening member 6. Thereafter the edges of the garment or container on which the fastening members are mounted may be entirely separated, and the edges of the coat, garment, or container thrown open any dis tance. In closing the opening between the edges of the garment, or container, the lower terminal member 6 is first placed over the hooks 8 and then the slider is moved upward in the usual manner, to cause the interlockprior application.

Having thus described this form of my invention, I do not wish to be understood as being limited to the details of form or specific arrangements of parts herein set forth, for various changes may be made in the design of the terminal fastener without departing from the spirit and scope of my invention, as set forth in the appended claims.

What I claim and desire toprotect by Letters Patent, is

1. Terminal fastening means for uniting the ends of series of complementary interlocking fasteners, comprising, a terminal member for one of said series, provided with hook portions having ends extending substantially parallel with the direction of the successive fasteners of said series and with transverse grooves, and a complementary terminal element having transverse grooves that are used to receive said hooking portions, whereby said terminal members may be hooked together and unhooked when said series of fasteners are disengaged.

2. Terminal fastening means for the ends of series of grooved interlocking fasteners having laterally extending bases, which comprises a male member having two hooks thereon comprising reversely bent portions extending parallel with the base thereof and a complementary female member having two transverse grooves above the base thereof and adapted to receive said hooks on the firstmentioned member, whereby said members may be unhooked after said interlocking fasteners have been disengaged.

3. Separable fastening means comprising two series of interlocking grooved elements having laterally extending bases, one series being provided with enlarged heads and having a terminal element carrying hooks comprising reversely bent portions extending parallel with the base thereof, and the other series being provided with a slot in each ele- ,ment through which the heads of the 0pposite series may pass and within which they are retained, the terminal element of said second series having transverse recesses extending parallel with the base thereof adapted to receive the hooks of the opposite terminal element, and a flanged slider whose flanges are adapted to enter the grooves in the elements of both series, the ends, of said bent portions on said hook element forming stops for said slider, and whereby said terminal elements may be unhooked after said interlocking elements have been disengaged.

Signed this 8th day of December, 1931.
