MULTIPLE OPERATED FASTENING' INSTALLATION Filed April 18, 1931 Patented Sept. 17, 1935 UNITED STATES PATENT OFFICE MULTIPLE OPERATED FASTENING INSTALLATION Application April 18, 1931, Serial No. 531,120

7 Claims. (Cl. 24-205)\ My invention aims to provide improvements in multiple operated fastening installations and particularly improvements in separable end fastening means which permitV complete separation l of the stringers of the installation.

In the drawing which illustrates 'a preferred embodiment of my invention:-

rFigure 1 is an enlarged plan view of a portion of i a multiple operated fastening installation showing my improved end fastening means;

Fig. 2 is a section taken on the line 2 2 of Figure 1;

Fig. 3 is a plan View of the end portion of the installation showing the slider in plan section and in the proper position for engagement and disengagement of the end fastening means; and

Fig.. 4 is a view similar to that shown in Fig. 3, but with the slider out of proper relation to the female member of the end fastening means but being moved toward lt by means of the male member which has been entered into the slider.

Referring now to the particular embodiment of my invention which is illustrated by the accompanying drawing, I have shown a multiple operated separable fastening. means which is particularly adapted for closures which must be completely separated at both ends at specified times. In the installation illustrated I have shown two stringers I and 2 to the adjacent edges of which are attached 'series of fasteners 3 of any suitable construction for uniting the edges of the stringers. The \usual slider 4 is provided for engaging and disengaging the fasteners 3 as is now well understood by those skilled in the art.

At adjacent ends of the stringers I and 2 close to the ends of the rows of fasteners 3 I have provided end fastening means comprising a female member secured to the stringer I and a male member secured to the stringer 2. These members are adapted to be separated by passage of the male member through o'ne side channel of the slider 4 and to be engaged by entrance of the male member into the slider only when the slider is located in a particular relation to the female member as will be hereinafter more fully described.

The male member is made of sheet "metal and has an integral tubular portion 5 of substantial length beginning adjacent to the edge -of the stringer 2 to which a series of fasteners 3 is attached. Extending inwardly from the tubular portion 5 in spaced relation are two flanges 6 and 1 (Fig. 2) of substantial area which are clamped against opposite faces of the stringer to hold the male member in ilxed relation to the stringer. A convenient means of attachment includes a number of prongs 8 pressed from the material of the flange 6 and passing through the stringer 2 and flange 1, the ends being upset as 5 illustrated in Figs. 1 and v2. Adjacent to that end of the tubular portion 5 of the male member I have provided a lateral projection 9 which is adapted to cooperate with the fasteners 3 in such a manner (Fig. 3) that improper engage- 10 ment of the fasteners 3 is impossible. The other end 5a of the tubular portion 5 is rounded to ride easily over the ends of the fasteners 3 (Fig.

4) and to enter easily into engagement with the female member. l5

The female member has a tubular portion I0 which is located adjacent to one end of a series of fasteners 3 secured to the stringer and is heldin position by flanges II and I2 extending inwardly therefrom in spaced relation and gripping 20 the stringer I between them. These flanges II and I2 are held in position by prongs I3 in the same manner as the flanges 6 and 1 of the male member. A slot I4 (Fig. 3) is cut into the outer edge of the tubular portion I0 to permit entrance 25 of the flanges 6 and 'I when the male member 5 is entered into the female member I0. The slot I4 does not extend the entire length of the portion I0 thereby leaving a shoulder I5 which provides a, stop against which the flanges 6 and 1 may engage to limit the entrance of the male member into the socket.

If we assume that the stringers are separated, the end members may be readily engaged no matter where the slider is located on the stringer 35 I. This is demonstrated by Figs. 3 and 4 of the drawing which show (Fig. 4) the slider spaced from' the end member III and Athe end member 5 entered therein. By moving the stringer 2 toward the left (Fig. 3) the member 5 and slider 40 4 are moved to a position where the slider 4 rst contacts with the cam shaped edges I6 provided in the flanges II and I2 of the female member by cutting slots or grooves in the said flanges. These cam edges I6 guide the slider 4 into proper 45 relation to the fastener members 3 and female member on the stringer and the slider is, therefore, held against any substantial lateral or rocking movement. In this manner the male member 5 is easily and accurately pulled into engage- 50 ment with the female portion III and the end members assume positions as shown in Flg.. 1. The edges of the flanges 6 and 1 contact with the shoulder I5 on the portion I0 and the upper edge 5b engages beneath the last fastener 3 on 55 the Stringer I, thus properly positioning the fastener members 3 so that the slider when pulled toward the right (Fig. 1) will engage them. In this manner the ends of the stringers I and 2 are properly locked together and cannot be separated by stresses exerted in any direction. If an attempt is made to engage the fasteners 3 on the opposed stringers I and 2 while the parts are in the positions, as shown in Fig. 3, the lateral projection 9 on the member 5 would engage the ends of the fasteners 3 on the Stringer I and any attempt to move the slider 4 to the right would result in the parts becoming jammed. Therefore, my device is fool-proof to the extent that the end fasteners must be properly engaged before the slider can be operated to engage the fasteners 3 on one Stringer with the fasteners 3 on the other Stringer.

Separation of the stringers is eily and quickly effected by simply pulling the slider 4 towards the end members and then moving the Stringer 2 longitudinally relative to the Stringer I to pull the male portion 5 through the slider.

My end members are made in one-piece units from sheet metal and are simple and durable in construction, inexpensive to manufacture and easy to attach.

While I have illustrated and described a preferred embodiment of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claims,
