11 Claims.

This invention relates to sliders used in conjunction with slide fasteners in coupling and unv and annexed 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. l is a side and sectional view of a slider made according to the invention with part of the construction broken away.

Fig. 2 is a plan view of the structure as seen in Fig. 1, with part of the construction broken away and in section.

Fig. 3 is a view substantially similar toFig. 1,

the section being taken in a different transverse plane and also showing parts in a different position; and,

. Fig. 4 is a perspective view of a lock element employed, detached.

In lock sliders of the kind under consideration it has been a common practice to employ a lock element as an integral part of a pull or other manually actuated member; and with devices of this type and kind, quite often it is experienced that the pull is supported in a raised positon with respect to the slider wall by engagement of the pin or other part of the lock element with a link in such manner as to support the pull in said raised position. This experience has been objectionable, particularly in the laundering as well as'the pressing of garments having this type of fastener device thereon. oftentimes-the slider or lock parts thereof have been rendered inoperative by bending or breaking the lock parts in the pressure applied thereto in passing through various types of laundering and pressing machines.

It is one of the distinctive features of our invention to provide a lock slider which will overcome the above and other objectionable characteristics in providing a lock element which does not interfere with the automatic return of the pull to a collapsed position upon the sl der wall,

and further in providing a lock element capable of movement independent of the pull, partieularly in moving the slider longitudinally. of the stringers to couple the same by any other means or manner other than engagement of the pull. Still further, a lock element is provided which is free to move independent of the pull from an inoperative or raised position into an operative position in automatically'locking the slider by stress or strain applied to the stringers tending to separate the same or to move the slider along the stringers in the opening direction.

In the accompanying drawing, one adaptation of the invention is shown. Considering Fig. 1, l0 represents a slider body of more or less conventional general form; that is to say, it comprises spaced top and bottom walls H and I! joined at the wide end portion of the slider in a connecting web IS with the walls of the slider having inwardly extending side flanges It.

In the construction shown, the top wall I I, note 'Fig. 2, has transversely spaced bearings [5 between which the wall II is recessed as seen at l6, and one end of the recess opens into an elongated aperture I? which opens into the channel l8 of the slider to engage the links of at least one stringer; one of the links being indicated in part in dot and dash lines I9 in Fig. 3 of the drawing.

As the stringer structure is well known in this art, no detail showing is made thereof.

At tllis shown part of a finger piece or pull which may constitute any type andkind of a manually actuated member; and this pull has a yoke-shaped end formed by spaced bearing portions 2| pivoted to the bearings l5 by a pivot pin 22, the ends of which are riveted or otherwise secured to retain the pin against displacement Arranged upon the pin 22 between the bearing portions 2! of the member 20 is a substantially semi-cylindrical lock element 23 which might also be termed a hood element in that the outer curved wall of this element jackets the pivot pin intermediate the bearing portions 2|. The element 23 includes and discs or hearing portions M, apertured as seen at '25 to receive the pin 22. One of these end walls or discs includes an integrally projecting lock part 26, commonly re- I ferred to as the lock pin; and this pin is adapted to drop between adjacent links of a stringer in retaining the slider against movement thereon in one, 'or opening, direction. The lement 23 also preferably includes at one edge wall of the curved portion thereof a projecting lip or flange draw the lock pin or part 26 out of the channel 18 of the slider into a position as indicated in Fig. 3 of the drawing, or a position beyond the position shown.

The wall of the hood lock element 23 is spaced beyond the pin 22 suiliciently to receive a coil spring 29 which encircles the pin 22, one end 30 of the spring engaging the element 23, and the other end 3! entering an aperture 32 in the recessed portion it of the slider, the spring tending to normally support the element 23 in the locked position shown in Fig. l of the drawing, with the lock pin or part 25 projecting into the channel i8.

In the normal locked position of the slider the hood portion of the element 23 substantially conceals the pin 22 as well as the spring arranged thereon, and in the normal operation of the slider, when it is desired to move thesame along the stringers to couple the stringers, the raising of the pull or member 20 will automatically rotate the lock element and raise the lock pin or part 23 out of the channel l8 providing free movement of the slider along the stringers; Upon releasing the pull or member 20, the lock ele ment then engaging the pull will automatically return the same to horizontal position with respect to the slider wall; andat the same time move the pin or part 26 into locked position.

However, should the pin or part 23 strike the upper surface of a link which would retard or check movement of the element 23 into operative position, the pull or member 20 would automatically drop by gravity onto the slider, but leave the element in the position shown in Fig. 3. It will thus appear that in the laundering and pressing operations heretofore referred to, the danger of bending or breaking the lock element by the forcing of the pull or member 20 from a position substantially similar to that indicated in dotted lines in Fig. 3, to the full line position, is

eliminated. The dotted line position represents automatically drop into position to engage the next link of the stringer to check further opening movement of the slider.

With the lock slider structure disclosed, it will be apparent that the pull or manually actuated member has a movement with as well as independent of the lock element; and in the construction disclosed, this element is disposed between the pivot ends of the pull. It will further be apparent that the lock element may have any type and kind of link engaging means to retain the slider against movement along the stringers.
