7 Claims. (01. 2 1-2051;)

This invention relates to sliders for separable fastener stringers. More particularly, the invention deals with sliders of what I term the side locking type, wherein the lock element of the slider is movable laterally with respect to the scoops of the stringers and normally held in position between adjacent scoops on a stringer in retaining the slider against movement in either direction thereon. Still more particularly, the invention includes means for automatically moving the lock element of the slider into inoperative position in actuating the pull of the slider to move the slider in either direction on the stringers. The novel features of the invention will best be understood from the following 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. l is a plan view of a slider made according to my invention, diagrammatically illustrating the same on a pair of stringers with parts of the construction broken away and in section.

Fig. 2 is a section on the line 2-2 of Fig. 1, showing the scoops of one stringer with the lock element therebetween.

Fig. .3 is a section on the line 3-3 of Fig. 1.

Fig. i is a section on the line 4-4 of Fig. 3, with parts broken away.

Fig. 5 is a perspective View of the lock element, detached.

Fig. 6 is a plan view showing a modified form of slider construction; and

Fig. 7 is a section on the line l-l of Fig. 6, on an enlarged scale.

In sliders of the kind under consideration, it has been the common practice to provide a lock element or pin member movable vertically into position between scoops of the stringers to look a slider against movement longitudinally of the stringer. Furthermore, this look element or pin member has formed a part of the pull and in the event that the pull becomes displaced, the slider has been free to move along the stringers, thus failing to perform the desired function.

It is the purpose of my invention to overcome the objectionable features to the present type of lock sliders by providing a look element which is 2 independently controlled insofar as movement thereof into locked position is concerned, and which may be moved into an inoperative or nonlocking position by exerting a pull upon the fingerpiece of the slider in either of two directions. During the interval when the fingerpiece is being pulled, the slider moves freely along the stringers in response thereto, but otherwise the fingerpiece is free for swinging movement on the slider without contributing any action upon the lock element to release it from locked position. It will also become apparent that in manually moving the slider along the stringers, the instant the pull is released, the lock element will automatically be moved into locked position by the spring employed.

In Figs. 1 to 5 inclusive, I have shown one adaptation of my invention, and in these figures, l0 represents the slider body comprising a top wall II and bottom wall l2, these walls being connected by a frog or web [3 at the wide end of the slider in accordance with conventional practice. The walls H and [2 have inturned flanges at their inner adjacent faces, as at [4 and I5, note Fig. 3, to define the channel iii in which the scoops l1-l'l of a pair of stringers l8l8', indicated in dot and dash lines in Figs. 1 and 3, are adapted to operate. The scoops are diagrammatically illustrated in Fig. l of the drawing and the scoops ll of the stringer l3 are shown in full lines in Fig. 2 of the drawing in order to illustrate the arrangement of the lock element, later described, between adjacent scoops in retaining the slider against movement on the stringers.

In the construction shown in Figs. 1 to 5 inclusive, the upper wall I I of the slider has on its outer face, an elongated recess I9 in which is mounted a retaining plate 20 for retaining a slide 2| against displacement from the wall H and within a narrower elongated aperture 22. The plate 28 is held in position by a plurality of inwardly turned lugs 23, note Fig. 1 of the drawing.

The slide 2| has substantially centrally of the outer surface thereof an upwardly projecting lug 2d, recesses at opposite side surfaces, as indicated at 25 in dotted lines in Fig. 3 of the drawing to receive inwardly extending pivot portions 26 on a pull 21. One end of the slide 2: has on the lower surface thereof a substantially triangular recess 28 defining diverging cam surfaces 29 and 30, note Fig. l. These camming surfaces intersect in a rounded intermediate portion 3!, in which a pin member 32 of a lock element 33 normally seats.

Considering Fig. 3 of the drawing, it will appear that the wall H has a transverse recess 34 which is enlarged at its inner end, as seen at 35, in Fig. 4 of the drawing. The element 33 is mounted in this recess to move laterally or transversely with respect to the movement of the slider along the stringer. The pin 22 projects upwardly-into. the recess 28, and the element 33 includes atiits outer end" a downwardly projecting lock lug 36 which is adapted to extend into the channel It in the normal lock position of the element 33 and to be positioned between adjacent scoops on a stringer, as clearly seen in Fig; 2'

of the drawing, and also indicated in Fig.v 3;.

The lug 36 operates in a further cutout portion 31 of the wall 5 i, which cutoutportion' ai'soopens" through the side edge of the slider wall, so as to permit outward movement of the element 33 including. the lug. 3.5,.to clear the channel l5., or to permit. free movement of the sccops through. the. channel. it of the slider. The element 33' carriesat. itsinner endia projectingfinger or'lug 3?. against which. one end 39. ofa d-shapedspring Allis adapted to bear to normally. retain the ele- 1 ment. 3B in locked. position. The other end 41' of. the spring. ail bears. against the wall '32 of the aperture. 22, the spring it being positioned below: the; slide. 2L. as. will; clearly, appear from acon.- sideration of. Fig. 2 of. the drawing.

From the.for.eg.oing,,it. will appear that when the. fingerpiece. or. pull 21 is in normal position, thaspring, MI supports the element33 in normal; position,,witli the locklug 36. between. scoops of" a stringer, for example, the scoops I! of the stringer !8, which position of. the parts is. shown in Figs. 1, 2.and 3' of the drawing; In grasping thepull 2! to move the slider'downwardly'to sep1- aratethe stringers, the slide 2| will move downwardly. in the top wall H, causingthe pin 32 to ride over the cam surface 29'; which: will move the lock element 33 outwardly against the action of. the spring 40 crime end 39. thereof, as seeninhi'g. 4' of the drawing;

In moving the slider upwardlyor in the opposite. direction, the slide 2! will move upwardly'or in the direction of the wide end. of" the slider ancl theipin 32 will move over'the cam surface 3'6, pro.- ducing' the same result, namely moving the lock element 33; outwardly or to the left. All of theabove descriptions are applied to the slider, as seen in the drawing: When. the pull- 21' is released; the slide 21- will be returned to neutral; position by'action' of the spring end 39-upon the finger or lug 33, which moves the element 33- into locked position and seats the pin 32in the rounded" intersection 31 of the recess 28, which position is indicated in Fig. 1 of the drawing.

In Figs. Band 7 of the drawing; I have shown a modification, in whichthe plate Zfl-is dispensed with and a'slid'e' 21 substantially similar-to the slide 21" is employed; the slide 2! having bevelled side walls 53 slidably engaging correspondingly formed elongated ribs M extending longitudinally of the top wall i i of' a slider.

Theslide- 2| has the pivot lug 24 similar to; the lug 24 and the triangular recess 28 similar to therecess 28. At 33 is shown a lock element substantially similar to-the element 33, and having a lock lug 36' at one end, an extension 38 at the slider wall H, as at 48.

' to the pin 32, which operates in the recess 28'.

In Fig. '7 of the drawing, [2 represents the bottom wall equivalent to the wall [2, and at I3 is shown the web joining the slider walls I II2 and at It is shown the channel. of. the slider. In. Figs. 6 and '7, the loch element. 335 is shown in locked position.

With the construction shown in Figs. 6 and '7, it. will.appear that the slide 2i is exposed at the outer'surface of the slider and is movable longitudinally thereof within the channel formed by the ribs 44. However, the operation of the slider shown in these figures will be the same as thatot theother figures insofar as actuation of the element 33 is concerned, and therefore, no further detailed description is hereingiven.

Returning now to Figs. 1' to 5 inclusive... it. will.

appear that the closure plate. 20" has an elongatediapertureill therein in which the pivotlug 2 3 of the. slide operates in movement of the slide longitudinally of the slider.

With. the constructionshownin Figs..1 to 4. inclusiye, it. will be; apparent that the lugs- 23. are normally opento admit the plate 2.4!. and in the assemblage. the. lock. element. 3.3. and spring 40.

are. firstplaced in position, the. element 33. passing, downwardly through an opening Ha. formed inthe wall 1.! after which the slide is placed upon said elementand spring andthen the platev 20 is a put into position, after which. the lugs 23. are forced inwardly.

Considering Figs. 6 and '7 of the drawing, here the. element 33" is first dropped in position through the opening 44" provided inone of the ribs 44. The spring 40" is, then placed in positi'on, after which the slide 2! is mounted. in

the. groove withthe ribs in anopen position,.the same as the lugs 23, thereafter, the ribs are bent inwardly to freely engage the bevelled walls 43 of the slide and thusretain the parts. in assembled relationship.

It will be understood that the slider body as well as the lock element and the slide can each readily be formed as die castings, and from this standpoint,. comprise independent articles of manufacture and assemblage can. be made at any time by simply turning in the retaining lugs or ribs. By reason of this construction, a. very simple and economical slider. structure is produced. As a matter of. fact, aside. from the. U- shapedspring employed; the entire slider device may' be composed of any suitablev die. cast material.
