Patented Aug. 26, 1941 I UNITED STATES PATENT oFricE REVERSIBLE SLIDER FOR. SLIDE 1 FASTENERS med ii; Carlile, Meadville, Pa.', assignor to Talon, Inc., a corporation of Pennsylvania Application March 25, 1940, Serial No, 325,763 6 Claims; (01. 24-2055) This invention relates to slide fasteners and.

in particular, to the provision, ofnew and imvide such a slider wherein manually engageable pull means of cord-like form is movably secured 10 to the slider in such manner that it may be readily engaged from either side of the slider,

extended on that side, and-readily manually engaged at a great number of angles and positions for opening and closing a slide fastener by .longitudinal movement of the slider with respect to the fastener. I

It is a further object of this invention to provide a slider construction which is reversible,

whereby the slider. might be operated by the same pull tab from either side of the slider, and of the fastener. I

Both of these constructions proved extremely inconvenient and uncomfortable in use because of the projection formed on'the underside of the slider,by the second pull tab in the first case,

and by the track or retaining slide in the second case. 1

Because of the necessity for the second pull tab in the first case, and the necessity for an extremely intricate and costly design of the retaining slide in the second case, the cost of these slider constructions was substantially increased over conventional sliders operable from one side only. I

In addition to the above disadvantages, the

projection formed by the second pull tab in the first case, and by the track or retaining slide in which is of simple and cheap construction, which the second case, proved a great disadvantage .or

is extremely durable, and which is of' pleasing appearance. 4 n

. These and other objects and advantages of the invention will appear from the following description taken in conjunction with the accompany- '25 ingdrawing, which forms .a. part thereof, and

will be pointed out in the appended claims.

In the drawing: I Fig. 1 is a view, in perspective, of a slide fastener slider according to this invention, as applied to one conventional form of slide fastener;

Fig. 2 is a longitudinal central section of the slider of Fig. 1, with the pull member in elevation;

Fig. 4 is a transverse section taken substantially on. the line 4-4 of Fig. 2.

In various applications of the slide fastener,

and, in particular, in their applicatio to re- 40 Formerly, use has been made in'such applica- -tions' of sliders having lugs of different type at opposite sides thereof, each of which lugs .is

provided with pull tabs.

In other constructions, the slider was prov :led

with a track or, retaining slide'extending over one wing or side of the slider, over the neck of the slider and over the other wing or side of the slider. Aiplate-like pull tab was slidably supported on this track or retaining slide for move-' Fig. 3 is a view similar to Fig. 2, but showing 35 the pull member in reversed position; and I tional slide fastener.

inconvenience due to its catching in clothing and in the skin of wearers of a garment provided art constructions are totally obviated, according. to this invention, single flexible pull member which is slidable endwise through an aperature or bore provided in the slider body, which pull member is provided at each end with a sto member for retaining it in the bore or aperature, and for limiting its I endwise movement in both directions.

Referring to the drawing, wherein I have illustrated one application of the principles of this invention, a slider, generally designated I0, is shown in its operative relation in a conven- The slide fastener includes a pair of stringers '5, each comprising a tape 8 having a reinforced edge 1 upon which is secured a row of interlocking fastener members 8. The interlockingfastener members 8 of the stringers 5- are progressively engaged and dis-' engaged in known manner by sliding movement of the slider l0 longitudinally of the fastener stringers 5. Conventional means such as the bottom stop 9 is provided for securing the ends of the stringers 5 together, below and adjacent the rows of interlocking fastener members 8.

The body of the slider I-llcomprises a pair of similar sides or wings ll secured together at their upper ends by a neck or wedge member I! and having marginal side flanges H which 00- operate with the lateral surfaces'of the' wedge member II to form an upwardly diverging subment from one side to the other side of the slider. stantially Y-shaped fastener member receiving by the provision 0! a channel for slidably supporting interlocking fastener members 8 in known manner. If desired,

suitable automatic locking means of the wing" lock type may be provided by the formation of locking projections or edges on the flanges I4 or by shaping these flanges, for instance, in the manner described in my copending' application Serial No. 285,375, filed July 19, 1939, which matured into Patent No. 2,214,705, granted September 10, 1940. Extending from side to side through the body of the slider I at its upper end is a pull member receiving bore or aperture I5 which is preferably disposed centrally of the width of the slider I0. Extending through this bore or aperture I5 is a cord-like flexible pull member I6 having similar stop members I I and I8 secured to its opposite ends.

In order partially to recess the cord-like or cable-like flexible pull member I61 in the exterior wing II of the slider in its inoperative position (shown in dash lines in Fig. 2), each wing II of the slider is provided with a longitudinal recess or channel I9 extending from the end of the bore I5 to the lower edge of each wing II. As shown in Figs. 2 and 3, the end edges of the bore or aperture I5 are bevelled at in order to enhance the flexibility of the pull member I6.

The flexible pull member I6 may be formed of any suitable textile or other material and may fit snugly in the receiving bore or aperture I5,

though readily manually movable endwise therethrough between the extreme positions shown in Figs. 2 and 3, respectively. When the fastener is to be operated from one side, the pull member will take one of the extreme positions of adjustment, with respect to the slider, as shown in Figs. 2 or 3.

If it is desired, after operating the slider from one side of the fastener (as shown, for instance, in Fig. 2) to operate the slider from the opposite side of the fastener (as shown, for instance, in Fig. 2) the appropriate end stop member, such as I8 in Fig. 2, is manually pulled outwardly of the slider to bring the flexible pull member I6 to its extreme reverse position (as shown in Fig. 3, for instance).

While a regular or non-separating bottom stop is shown in Fig. 1, for convenience of illustration, it is, of course, to be understood that other known forms of stringer end attaching means, such as separable bottom end fittings may be used. Separating bottom-end fittings will, in fact, -most probably be used in such relationships as in reversible garments where the use of such a slider, as is described above, and illustrated in Figs. 1-to 4, is most desirable.

It is, of course, to be understood that the-above description is merely illustrative of the principles of this invention and in nowise limiting andthat I desire to comprehend within this invention all modfications included within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a reversible slider for slide fasteners, a.

slider body having an interlocking fastener member receiving channel therein, and a flexible pull member extending through said slider body from front to back and movable endwise therethrough.

2. In a reversible slider for slide fasteners, a.

slider body having an interlocking fastener member receiving channel therein, a flexible pull member extending through said slider body from front to back and movable endwise therethrough, and stop means on said pull member for limiting endwise movement of said pull member with respect to said slider body.

3. In a reversible slider for slide fasteners, a slider body comprising a pair of similar wing members secured together at their upper ends by an intermediate wedge member, a bore extending through said wedge member and said wings from front to back of said slider, and a flexible cord-like pull member extending through said bore from side to side of said slider body and slidable endwise in said bore from front to back of said slider.

4. In a reversible slider for slide fasteners, a

limiting endwise sliding movement of said flex-' ible pull member and retaining said flexible pull member in said bore.

5.
