REVERSE LOCKING SLIDER Filed May 15, 1947 INVENT DAVIS MARI KY ATTORNE Patented Apr. 17, 1951 REVERSE LOCKING SLIDER Davis Marinsky, Bronx, N. Y., assignor of onehalf to Louis H. Morin, New York, N. Y.; Louis H. Morin executor of said Davis Marinsky, de-

1 This invention relatesto sliders as used on the stringers of separable fasteners to couple and uncouple the stringers. More particularly, the invention deals with a slider structure employing a vertically movable lock pin actuated by the pull of the slider in movement into operative and inoperative positions. Still more particularly, the invention deals with a slider structure wherein the pull is arranged to move toward and from the slider at the wide end thereof, adapting the same to a reversible usage, and wherein the slider wall has means which renders the slider substantially non-crushable. The novel features of the invention will be best understood from' the followin description when taken together with the accompanying drawing in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:
Fig. 1 is a perspective View showing a slider made according to my invention.
Fig. 2 is a longitudinal section through the lock pin portion of the slider, with part of the construction removed and diagrammatically illustrating the pin engagement with scoops.
Fig. 3 is a view similar to Fig. 2, showing the parts in a different position; and
Fig. 4 is a plan view of the slider as. seen in Figs. 1 and 2. y
In certain uses of separable fasteners, such for example, as on leggings, luggage and the like, the
wide end of the slider is arranged downwardly or in what might be termed a reversed position. In fasteners of this type and kind, it is desirable to employ a pull which will hangdownwardly, or in other words, will be movably disposed over the wide end of-the slider. With my improved construction, I provide a slider structure of this type and kind having means for locking the slider and also means for rendering the slider non-crushable when the parts are in the locked position.
In the drawing, It) represents a slider body having spaced upper and lower walls H and I2 joined at the wide end l3 or the slider in'a connecting web or frog I4. The walls Hand l2 have inturned side flanges I5 and I6 respectively, defining the channelstructure I l of the slider. The top wall of the slider has an elongated solid non-crush body portion I8 which is disposed over the web or frog l4 and extends forwardly and has at the contracted end portion thereof a transverse substantially cylindrical bore l9 partially formed by a raised rib portion 20 and by a curled flange portionZl.
9 Claims. (01. 24-20514) 2 I The slider is in the form of a die. cast body, and in initiallyforming the body, the flange portion 2| will extend substantially as seen in dot In the bore 24 is mounted a vertically movable lock pin or plunger 25, having at its lower enda lock lug or part 26 adapted to rest between ad I jacent scoops of a stringer, as at 21, Fig. 2. The
plunger or pin 25 has a transverse recess 28 near its upper end adapted to be engaged by a projecting lug 29 on thejpin' 22. The plunger or pin 25 is recessed, as seen at 30 and 3| to receive the pivot pin 22 as the pin moves from the position shown in Fig. 2, to that shown in Fig. 3. In the latter figure, it will appear that the corner portion 32 formed between the bores l9 and 24, forms a stop checking lifting movement of the pull 23, and accordingly, upward movement of the lock pin or plunger 25. 1
The pull 23 comprises, in the construction shown, a ring fingerpiece end 33 having side arms 34 which are integrally joined by the pivot pin 22. The arms and in fact, the entirepull lies in a plain below the upper surface of the body is in the normal lock position of the slider, as
will clearly appear from a consideration of Figs.
1 and 2, thus in laundering the garment, the slider becomes substantially non-crushable in the sense that the solid body structure provided at the wide end of the slider will take up any crush in strains to which the slider may be subjected.
It will be apparent that normally, the dropping of the pull upon the slider wall II will move the lock plunger 25 or its locking lug or element 26 into operative position, as seen in Fig. 2. However, when the pull is swung outwardly or up-' wardly with respectto the wall II, in operation of the slider to couple and uncouple stringers,
this movement of the pull will automatically raise the plunger 25 into the position as seen in Fig. 3,
freeing the scoops of the stringers for movement' through the slider channel.
Considering the disclosure in the drawing, it may be said that the solid non-crush body terinmates at its end in a substantially cylindrical elongated bearing portion initially formed by the inturned flange, this bearing portion having'the portion, and preferably disposed at one side of the body 118, offset with respect to the slider center to facilitate engagement with the stringer scoops.
It will also clearly appear from a consideration ,of Figs. 1 and 2 of the drawing, that the arms said body having a transversely elongated bear-- ing, a pull having a pivot pin mounted and swingable in the bore of said bearing, said body having a vertical bore intersecting thebearing bore, said pivot pin having a lug extending into said vertical bore, a plunger mounted in the vertical bore and having a transverse recess in which the lug of said pin operates to move the plunger upwardly and downwardly in swinging movement of the pull, and said plunger having a lock element at its lower end adapted to extend into the channel of the slider device in the inward movement of said plunger.

A reverse locking slider comprising a channelled slider device defined by walls spaced and joined at the wide end of the device in a connecting web, one wall of the slider above the web and centrally and longitudinally of said wall having a non-crush body, one end portion of said body having a transversely elongated bearing, a pull having a pivot pin mounted and swingable in the bore of said bearing, said body having a vertical bore intersecting the bearing bore, said pivot pin having a lug extending into said vertical bore, a plunger mounted in the vertical bore and having a transverse recess in which the lug of said pin operates to move the plunger upwardly and downwardly in swinging movement of the pull, said plunger having a lock element at its lower end adapted to extend into the channel of the slider device in the inward movement of said plunger, said pull having a finger-piece end joining the pivot pin end in side arms, and sa d pull in its entirety being disposed below the outer surface of said body in the nor mal locked position of the slider device.
3. A reverse locking slider comprising a channelled slider device defined by walls spaced and joined at the wide end of the device in a connecting web, one wall of the slider above the web and centrally and longitudinally of said wall having a non-crush body, one end portion of said body having a transversely elongated bearing, a pull having a pivot pin mounted and swingable in the bore of said bearing, said body having a vertical bore intersecting the bearing bore, said pivot pin having a lug extending into said vertical bore, a plunger mounted in the vertical bore and having a transverse recess in which the lug of said pin operates to move the plunger upwardly and downwardly in swinging movement of the pull, said plunger having a lock element at its lower end adapted to extend into the channel of the slider device in the inward movement of said plunger, said pull having a fingerpiece end joining the pivot pin end in side arms, and said pull in its entirety being disposed below the outer surface of said body in the normal locked position of the slider device, and means checking outward swinging movement of the pull in movement of the plunger into raised position.
