SLIDE FASTENEB Application med December 3, 1938. Serial lo. 645,505.

This invention relates to the class of devices known as slide fasteners, in which cooperating fastener elements are engaged and disengaged by means of a slide operating over the same. Y

The objects of theinvention are to enable the slide being operated from either side of are attained by the novelfeatures of construction, combinations and relations of parts 2 hereinafter described, illustrated in the accompanying drawing and broadly covered in the claims.

In the drawing, one sim le practical embodiment of theinvention 1s illustrated, but

it is to be understood that the structure may Stringer appearing in section.

`be modified as regards this particular disclosure, all within the true intent and broad scobpe of the invention.

ig. 1 in the drawing is a broken front or face vew of the fastener.

Fig. 2 is an edge view with the tape or Fig. 3 is a cross-sectional vlew as on substantially the plane of line 3--3 of Fig. 1.

Considering the structure in detail, the interengaging coupling or fastener elements are indicated at 5, carried by tapes or stringers 6, and adapted tobe engaged and disengaged by the Y shape slide 7.

Actuating means for the slide are shown provided in the form of a tab or pull 8, and Athis handle member is reversibly connected with the slide, so that it may be used equallyT -well at either side of the fastener. In the illustration, the reversible connection for the pull comprisesa loop 9, extending over the crotchportion of the Y slide from one side to the other, the pull handle having an opening 10 therethrough receiving the loop andi enabling the pull to be freely turned over from one side to the other of the slide.`

In addition to being operable from either side, the slide can be locked in its positions of adjustment at either side of the fastener, by reversible locking -means, consisting in the present disclosure of the lugs or

prongs

11, 12, projecting from opposite faces ofthe reversible pull and adapted to enter'through the

guide openings

13, 14, respectivelyI in t e opposite faces of the slide. l

In the position shown in tlie full lines in the several views, the locking prong 11 projects through the opening 13, into engagement between adjacent fastener elements, thereby securing the slide in this particular position and it will be evident, that upon reversing the pull, that is! by turning it up over the loop 9, in Fig. 2, the other lug v12 can be 'thrust through the bpening 14 in the opposite sidev of the slide into interlocking engagementI with the fastener elements. Hence, the slide can be operated and secured in its adjusted positions at either side of the fastener.

For yieldingly retaining the combined handle and reversible locking member in its locking positions at opposite sides of the fas-l tener, special means are provided, consisting in the present disclosure of the spring tongues `15, 16, struck out from opposite faces of the pull and designed to snap under the lower ed e of the slide as indicated particularly in ig. 2. one serving as a spring retainer for the locking member at one side of the slide and the other as a spring retainer for the locking member 'at the opposite side of the slide.

To guard the projecting locking lug which is not in service, special guard projections 17, ma be turned up from the slide, as indi-y cated m Fig. 2, and as shown at the rightl in Fig. 1, where one of these guards is shown standing at one side of the outwardlyprojecting locking lug 12.

In order that the pull may be conveniently used at either side of the astener and particularly without slipping idly up and down in the reversing loo 9, -said loop may be formed with lateral'o sets as indicated at 18,v

Fig. 2, into which the pull will naturally seat as it is turned up from the locking poslk tion at either side of the slide, the broken lines at the right in Fig. 2 indicating this relation in which the pull is restrained or temporarily-retained in the position for best actuating the slide. These offsets may be undercut somewhat to leave projecting shoulders 19 at the entrances thereto, adapted to prevent the pull accidently slipping out of position during the slide actuating movements. The offsets 18 in the reversin serve as guards for the

lockingl ugs

11,12, which, in their projecting relations stand between these offsets, and the guards 17.

In a slide fastener, the combination of cooperating interengaging fastener elements and a slide for'lacing and unlacing the same, actuating means reversibly connected with saidslide and operable to shift the slide at either side of the fastener, locking means operable by said actuating means at either side of the slide, whereby said slide may be shifted and secured in its osition of adjustment at either side ofthe astener, said actuating means includin a handle and said lockingv means inclu ing lugs projecting from the opposite faces of sald handle for cooperation with the fastener elements in reversed vpositions of said handle at either side of the slide and said slide having guide openings in opposite sides of the same for receiving and positioning said oppositely projecting locking lugs 1n the positioning of the handle at opposite sides of the slide.

2.
