Application May 17, 1945, Serial No. 594,192

2 Claims. (Cl. 2li-205.14)

This invention relates to a separable fastener,

more particularly to the slide for operating -fas\ i teners of this type.

Sliders for separable fasteners may move along the separable fasteners due to strains placed on the separable fasteners after separated or through other causes and it is desirable to lock a slider on the separable fasteners in some position along the stringers on which the fasteners are positioned. Various means of applying pressure on one or the other of the fasteners or by use of a projection extending between the fasteners have been attempted. Usually these constructions are expensive to produce and require precision formation.

One of the objects of this invention is to provide a simple and inexpensive lock for a slider to prevent the slider from movement along the fasteners.

Another object of this invention is to provide a lock for applying pressure in such a direction that a firm support is provided and considerable pressure may be applied in order to frictionally lock the slider in position.

Another object of the invention is to provide locking means which will provide pressure on the fasteners after separated against flanges provided on the slider.

Another object of the invention is to release this locking means when the pull tab is lifted for actuation of the slider along the fasteners.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims` In the accompanying drawings:

Fig. 1 is a top .plan view of separable fastener and a slider positioned thereon of the construction of this invention;

A Fig. 2 is a rear view illustratingthe .bottom plate of the slider as broken away to illustrate the position of the locking means;

Fig. 3 is aperspective view of the pull tab showing the locking means as provided thereon;

Fig. 4 is a perspective view of the slider with the pull tab detached;

Fig. 5 is an enlarged view of the slider with the front wing removed.

In proceeding with this invention I have modifled the slider for separable fasteners by cutting away a portion to permit the locking means carried by the pull tab to extend through the cutaway portion of the slider` to engage the separable fasteners for holding the same in locked position. This lock consists of a tongue provided on the pull tab to extend through a central opening in one of the plates of the sliders so as to engage the separable fasteners adjacent their point of 'separation and apply pressure outwardly on these fasteners so that they will engage flanges on the slider to firmly hold the slider in position.

With reference to the drawings, IIJ designates one part and Il; another part of some garment or material which it is desired shallv be separably connected together. A stringer I2 is sewed onto the part I0 and a stringer I3 sewed onto part II. Each of these have clamped upon them separable fasteners I4 with interlocking ends I5 so as to inter-engage as at I6 shown in Fig. 1.

A slider designated generally Il and shown in perspective in Fig. 4 consists of a pair of plates,

the top plate being designated I8 and the bottom plate designated I9, which are held together through means of a post or neck 30 which serves as a separator and guide for the fasteners I 4 to move them from locking position. This slider is flared outwardly at its upper end as at 20 so as to accommodate the separated portions of the fasteners after the slide has been moved along them.- Flanges 2l and 22 are provided on these plates for the guiding of the fasteners through the slider.

A pull tab 25 is hingedly attached to the slider I1, such for instance as by means of raised stock 26 of the plate I8 to receive portions of the pull tab 25 in the eyes so raised therefrom.

A finger 21 is provided on the pull tab 25 so located that it will swing through the opening 28 in the plate I8 and extend down into and between the fasteners I4 just as they are separated in the slider. The size of this nger will be such that it will engage and spread the fasteners apart forcing them against the flanges 2| and 22 so that a binding action occurs by reason of this outward pressure caused by the moving inwardly between them of the finger 21. By this arrangement when the pull tab is swung into position shown in Fig. 1 where it parallels the locked fasteners the finger will be moved into this locking position whereas when the pull tab is lifted from this position by reason of swinging around its hinges the finger will be withdrawn and the slider may be moved along the fasteners in a normal manner.

I claim:

1. A slider for a slide fastener of the type which includes a pair of stringers having rows of spaced interlocking fasteners alongtheir lon- 3 gitudinal edges, comprising in combination a. pair of plates spaced to' receive the interlocking fasteners. a pull tab hinged upon one plate, said plate having an opening therein at a location substantially where said fasteners separate by reaof the movement of said slider. a nger on said pull tab located to move through said opening and o! a size wider than the lateral space .between the fasteners at the location of said open- .ing to extend between' fasteners on opposite gstringers for engaging`-them and forcing them apart against portions of said slider.

2. A slider as set 'forth in claim 1 wherein said slider is provided with side ilanes and said nnger forces the fasteners against said flanges to lock the slider in position.
