3 Claims.

My invention aims to provide improvements in slider devices for use in connection with multiple operated fastener installations.

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

Figure 1 is a front elevation of a portion of a multiple operated fastener installation showing my improved slider device;

Fig. 2 is a front elevationof the device shown in Figurev 1 but with the cover plate moved to open position; r

Fig. 3 is a section taken on the line 3-3 of Fig. 2; and

Fig. 4 is a section of a portion of the pull-tab and cover plate of the slider device taken on the line 4-4 of Figure 1, the remainder of the installation being omitted.

In the annexed drawing I have shown as a multiple operated fastener installation a slider, the usual stringers 1--1 and the separable fasteners 2 secured to adjacent edges of the stringers.

The slider which comprises an improvement in the installation illustrated has fastener-operating means 3 of usual construction adapted to engage and disengage the fastener elements 2 when moved to and fro lengthwise of the stringers l l. In the particular. structure illustrated the slider has a pull-tab 4 hinged to a loop 5 (Fig. 3) provided on the fastener-operating means 3. At the free end of the pull-tab 4, I have hingedly attached a concealing plate 6 which when in one position (Figure 1) conceals both the pull-tab and the fastener-operating means. In the other position the concealing plate 6 reveals the pulltab 4 and the fastener-operating means 3 and provides additional length to the pull-tab so that when it is grasped the fastener-operating means 3 may bemoved relative to the fastener members 2.

In the particular structure illustrated the concealing plate 6 is hingedly connected to the free end of' the pull-tab 4 by suitable pivot pin pnr-' tions 7-7 formed integral with the concealing 'plate'and extending into loops 88 (Fig. 2)

' formed as integral portions of the pull-tab 4.

The concealingplate 6 is held in concealing position by a spring finger 9 (Figs. 2, 3 and 4) formed integral with the pull-tab 4 and adapted to cooperate with a loop or cam portion 10 lo cated between the pivot pin portions 7--'7. When the concealing plate 6 is in concealing position (Figs. land 4) the spring finger 9 bears against the edge of the cam portion 10 (Fig. 4) thereby holding it against accidental displacement from the concealing position. To move the concealing 1932, Serial No. 630,693

plate 6 about its pivot it is merely necessary to grasp the free end thereof and pull upwardly relative to the pull-tab 4. The opening movement islimited by contact of the shoulders 11 with the pull-tab 4, at each side of the spring finger 9, as bestillustrated in Fig. 3.

It is a purpose of my invention to provide a simple, inexpensive means for concealing the rather unornamental slider devices now commonly used so that a neat and ornamental device 10 will be presented. The above specifically described construction accomplishes the desired result without interfering with the operation of the slider device. Furthermore, my concealing plate 6 is so constructed and arranged, with re- 15 lation to the pull-tab 4, that the slider may be operat'ed without moving the concealing plate from the position shown in Figure 1 to the position in Fig. 2. I

While I have illustrated and described a par- 20 ticular embodiment of my invention, it should be understood that the concealing plate 6 may be attached to the pull-tab 4 and any suitable fastening means may be used, in place of the spring finger 9 and cain 10, to accomplish the desired result without departing from the scope of my invention which is best defined by the followin claims.

I claim! 1. A slider for a multiple operable fastener installation comprising, in combination, fasteneroperatingmeans for engaging and disengaging the fastener elements on opposed edges of stringers, a pull-tab secured by a hinge structure to said fastener-operating'means in a manner permitting movement thereof only in a direction directly toward or away from one face of the fas tener-operating means, and a plate member secured by a hinge structure to said pull-tab and normally in a position concealing the pull-tab and the fastener-operating means, and the axis of each hinge structure being parallel to the other.

2. A slider for a multiple operable fastener installation comprising, 'in combination, fasteneroperating means for engaging and disengaging the fastener-elements on opposed edges of stringers, a pull-tab hingedly secured to said fasteneroperating means, a plate member hingedly secured to the free end of said pull-tab and concealing the pull-tab and the fastener-operating means and a yieldable finger on the pull-tab adjacent to the hinged connection between the pulltab and the plate member and operable to hold the plate member in concealing position whilebeing operable to permit it'to-be moved out'of con- 55 cealing position about its hinged connection with the pull-tab.

3. A slider for a multiple operable fastener installation comprising, in combination, fastener- 5 operating means 3 for engaging and disengaging the fastener elements 2 on opposed edges of string ers 1-1, a pull-tab 4 hingedly secured to said fastener-operating means 3, a concealing plate 6, hinge pin members '7-7 and binge pin receiving loops 8-8 hingedly connecting said concealing plate 6 to the pull-tab 4 and a spring finger 9 and cam portion 10 adjacent to the hinged connection between the pull-tab and concealing plate providing means for holding the concealing plate in position for concealing the pull-tab 4 and the fastener-operating means 3.
