ATTORNEY United States i Patented, .Septf 2,7. 11960 l REVERSIBLE ACTION AUTMATIC LOCK' SLIDER Louis H. Morin, Bronx, N.Y (1.25 Beechwood Ave,` New Roohelle N-.Y.).

Filed May 15, 1958,. Ser. No.y 735,495'

i3 Claims. (Cl- 24F-205.14)

wherein a yoke enveloping the slider walls is pivotally mounted upon one wall of the slider and tensional means is employed for normally supporting the locking lugs of the yoke in operative position.

Still more particularly, the. invention deals with a slider structure of the character described wherein each pull disposed on opposed walls of the slider can opera- Ytively engage the yoke in movement of the locking'lugs into inoperative position against the action of said spring for movement of the slider along the stringers.

vThe novel features of the invention will be best 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 suitablereference characters in each of the views and, in which;

Fig. l is a face view of one side of a slider made vaccording to my invention, with part of Vthe construction shown in section and with part broken away.

Fi-g. 2 is a view similar to Fig. 1 illustrating Ythe reverse side of the slider with part of the construction broken away.

Fig. 3 is an enlarged sectional view on the broken line 3-3 .of Fig. 1, with -parts ofthe construction shown in elevation; and

Fig. 4 is `a sect-ion on the line 4-4 of Fig. 3, omitting all background showing.

Considering Fig. 3 of -the draw-ing, I have shown at 10 a slider having a pair of walls 11 and 1,2. joined and spaced by connecting web 13 at the wide end portion 14 of the slider body, these wide end Vportions being illus trated in lFigs. l vand 2 ofthe drawing,

At 15 and 16 respectively are shown the inwardly extending anges at adjacent surfaces of the

walls

11 and 12 ,for `[guidance of the Ascoops 1of separable fastener stringers into the .channel of .the slider fbody, as with other devices of this type and kind.

-At 17 fin Fig. -3 of VVthe drawing, 'I have indicated in :dotted lines diagrammatically the position of a Ascoop uwithin the -ohannel rof 'the lslider, particularly indicating fitsengagement -with the llocking lugs `o f the slider `later described. l

The Wall 11of the-slider has at `the wide end portion thereof a projecting lug 1 8 having a l transverse aperture 19 therein, as clearly noted in `Fig. 1 of the drawing. *.lhisf'wall.of.the slider, including the -web 13, has a deep 'ipertfurex'll) for wthe-receptionofand'rnountingofgr coil `spring 221. '-flhe-narrowendlportion of the Wali "11 has an outwardly projecting stop bridge 22 and the wall 11 has an elongated aperture 23 which extends beneath the bridge 22, as clearly noted in Fig. 3.

Tho` wall 1 2 of. the. .Slider has, Centrally of the gud of the wide ond: portion 14 of the Slider a projecting abutmoet Z4. Wall 152. at the narrow end portion has a proieotori 25. for the. purpose of; balancing: the appeararee. of the Slider at 'both walls thereoi, the projeotion terminating adiaoout the wide end 14 of the slider in Slot 26, note Fisofthe drawing, this slot being adapted --to rooeire aud'sude a p roieoting' tongue 2-1 at one'end of a looking` volte, 22%.'. The end ofthe' yoke 2a having the. projection includes. an inwardly protesting. shoulder 2 2 in conjunotion with which the. rounded pin end 3,4) 0f olio pull 3 1 is. adapted to operate as later described.

The other endY 'portion of.' the yoke 2:8, includes a pair 0f Qffei locking lugs 52 Whisk are adapted to operate in coniuuotion with the' fastener scoops in retaining the slider in looked position upon the stringers of a 'separable fastener. This ,end portion ,of the yoke 28 includes a PrDJQCtllg finger 'adapted; to operate in conjunction with the. proiooting bridge 2.2- in checking outward swinging movement of the yoke in operation ofthe pull 31 or the pull ,34 arranged upon the wall 11.

It wil-1 appear from a consideration of Fig. 3 of the drawing `that the innermost locking lug 32 has a long beveled sur-tage in `Coniuriction with which the pin ond 36 oi the pull lift operates in swinging the'yoke p'ut- W'ardly in mQuernent .of the lugs 32 into inoperative posiihm with, respetar to the,v scoops. This same result is a'ccomplished by engagement of the pin end 30 of the 121111.31 with the inwardly projecting shoulder 29.

It. will appear from a consideration of Eig. Elr of the draw-ing that. the. end portions of the yoke 28, including the, 111g 32, are. free to nuove in the aperture 23V of the wall 11.

The second named .end vportion of the yoke 28 has substantially centrally thereof an aperture 37 for free reception of the lug `18 and opposed walls 3S, bordering the aperture `3,7, includes inwardly projecting pivot pins 39 note Fig. 1 ofthe drawing, which operate in the yaperture 19, ,0f the lug 18.

The yoke is preferably a ,die cast 4part and in the casting .operation `the walls 38 are spread suiiiciently to clear the Vpiyotpins 39 over the lug 18, after which pressure is applied to the kside walls 38 to move the pins` 39'i`nto operative .engagement with the lug 18, the .result of 'this `Operation ibeing `shown on .the finished product asv-illus* trated Lin Fig. Vl of ,the drawing.

It vwill appear from va .consideration of Fig. 3 of the drawing that the side .walls 3S include inward extensions, one of which is shown at 38 in 'F.ig. 3 of the'drawing, tto provide ample bearing surface upon the llug 18 and also to partially housethe'spring 21.

v'ilhe projections 38' form a .recess 40 in the yoke adjacent the laperture `37, and .the base of the recess includes 1a projection 41 .upon .which .the outer end .portion ,of the spring 21 is seated, .as hlearly noted in Fig. 3 of thedrawing.

While thecposs thead portion 42 of the yoke could .integrally join .end .portions .of theyoke, in the structure Y.as Lshown the ,yoke .is made of along part 43 and a short part 4A, rand considering Fig. 4 of `the the drawing it .will appear `thatthese parts have reduced ,..overlapping .

portions

45 and 46 respectively,leachhaving 48 are'riveted overfas diagrammatically noted in Fig. 4

of the drawing, the crosshead 42 of the yoke is made as one.

It will appear from a consideration of Fig. 3 of the drawing that in movement of the slider in the direction of the arrow 51 by either of the

pulls

31 and 34, the lugs 32 will be moved into inoperative position, permitting free movement of the slider along the fastener stringers. On the other hand, in movement of the slider in the direction of the arrow 52 by leither of the

pulls

31, 34, the pull 31 or the pin end 30 thereof will strike the abutment 24, whereas the pin end 36 of the pull 34 will strike the lug 18, and the yoke will ratchet over the fastener scoops, which ratcheting is against the action of the spring 21 as will be apparent.

It will appear from a consideration of Fig. 2 that the pull 31 has a large aperture 53 to clear the projection 25 when the pull is in collapsed position, and the pull 34 has an aperture 54 to clear the bridge 22 when the pull is in collapsed position, the

apertures

54 and 53 being clearly shown in Figs, 1 and 2.

By way of summary, and for descriptive purposes the long part 43 of yoke 2S may be termed a lock element or lock element portion, and this is pivotally attached to one wall of the slider and has locking projections 32. The short part 44 of yoke 28, which is disposed on the opposite wall, may be termed a member, and this is joined to the lock element by means, disposed outwardly of the web, comprising the crosshead portion 42, there being thereby formed the yoke or yoke-like piece 28. A second member 25 is immovably iixed to the said opposite wall. The first member 44 movably engages the second member through the

interengaging means

26, 27, the interengaged members thus simulating the lock element portion 43. As noted, each pull when drawn in the fastener-opening direction engages and moves the said yoke-like piece about the pivot of the lock element portion thereof, thereby to.move the locking projections out of the channel and to unlock the slider. When either pull is drawn in the fastener-closing direction, it engages a fixed portion of the slider, projection 18 or abutment 24, so that the yoke-like piece is not moved about the said pivot and so -that the locking projections ratchet over the fastener.
