UNITED STATES PATENT OFFICE Y SEPARABLE Easl'rrmaa sLmEn Loox Davis and [anis II. Morin, Bronx, N. Y. Application April 23, 1942, Serial No. 440,448 v cunts.A (ci. z4-zo5.5)
This' invention relates to separable fasteners employing sliders movable along the stringers to couple and uncouple the same. More particu;` larly, the invention relates to a slider having a iiangless side portion permitting free lateral movement cfthe links of one stringer there'- through in providing a jam locking ofthe slider The slider comprises a top wall I0, a bottom wall Il spaced from the top wall by a connecting upon the stringers, when the latter are subjected to lateral stresses or strains tending to separate the stringers. The novel features of the invention will be best understood from the following description when taken together withfthe accompanying drawing,in which certain embodiments vof 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 plan view of a sectional portion of a fastener illustrating the slider in locked or jammed position thereon. l I
Fig. 2 is a perspective view of the slider detached; and, l
Fig. 3 is a view similar to' Fig. 1 diagrammatically illustrating the slider applied to stringers having straight links. l
in various uses of separable fasteners of the kind under consideration, the stringers are subjected to lateral stresses or strains tending to separate the stringers and to move the;v slider along the stringers and, to check such undesir` able separation, automatic locks of various types and kinds have been employed on the slider structure. These locks represent an added cost to the production of the slider and, furthermore,
are not entirely fool-proof.
It is the purpose of our invention to provide an economical slider structure which will automatisliders not only from the standpoint of the cost the parts, but also from the standoi. producing the lock parts upon the slider point of assembling body.
In Fig. 1 of the accompanying drawing, 5 rep-` resents portions of two stringers, on the vbeaded edges 6 of which are secured links or scoops 'l of the kind having angular oiiset mounting end portions '8 which produce on the resulting fastener what .is termed a herring-bone or chevron effect. This type of stringer construction is one adaptation of the invention.
webv or frog I2 arranged centrally of the wide end portion of the slider. The frog I2 divides the slider into diverging channels I3, I 4 at the wide lend portion of the slider, which channels converge into a single channel I5 at the narrowend portion of the slider.
On the top wall l0 is an elongated bar or other member I8 forming means for coupling a. finger piece or pull I1 therewith.
The walls Il), I I have at their peripheral edges of the channeled side I3 thereof short, inturned anges Il which extend from the narrow end portion a short distance toward the wide end of the slider leaving a large unchanneled opening I3 between the walls at the Wide end portion of the slider. The other side edges of the walls I1), Il have4 inturned llanges 20 extended the full length thereof, as is the usual custom. .In other words, the flanges It are of sufficient length to insure coupling engagement between the links 1 and leaveA large openings IQ to permit free lateral movement of one of the stringers 5 through the side of the slider, as seen in Fig. 1 of the drawing.
When the stringers 5 are subjected to a stress or strain in the direction of the arrows 2l, 22 of Fig. l of the drawing, the left hand stringer,
as .seen in Fig. -l, will extend substantially at right angles to the remainder of such stringer in more or less of a sharp bend; whereas the other stringer assumes a more gradual curve being restricted by the anges 20. This straining of the stringers operates to tilt the slider body sub- 4 stantially in the' manner illustrated in Fig. 1, causing the ends 23 of the flanges I8 to engage one of the links l on the left hand stringer, whereas the ends 24 of the flanges 20 engage one of the links of the other stringer, thus jamming the slider' against further opening movement For purposes of description, the slider may be described as having a fully closed channel side and a partially closed or open channel side, one
stringer being freely movable laterally through the opening in said last mentioned side.
The dei and dash une 2s,.sho'wn in Fig. 1 of the drawings represents the longitudinal axis of l the slider, and with the slider'in the tilted position illustrated, it will appear that the stressed left handrend portion 26 of the stringer extends at an angle less than 90 to the center line of the slider considered with respect to the narrow end portion thereof, whereas thestrained .end portion 21 of the right hand stringer extends at an angle greater than 90 to the slider center as represented by the line 25. Thus it may be said that the slider has a side opening permitting Y lock slider constructed substantially asdescribed is adaptable for use on separable fastener stringers or chains having links or scoops of any de-l sired construction. In` other words the conventional straight link o'f common usage can be employed.
' Fig. 3 of the drawing shows diagrammatically -the slider arrangement upon conventional straight linka, and in .this figure, small portions of stringer tapes 28 are shown with straight links tion of the slider forming a continuous channel longitudinally thereof, the other side portion of the slider having means at the narrow end portion onLv thereof forming a longitudinal channel, and the wide end portion of the second named side of the slider lhaving an opening equal in width .to the spacing of inner surfaces of the slider walls.
4. A slider for separable fasteners having series of fastening links mounted on stringers, of the type having a pair of flared walls having side edge portions, wide end portions and narrow end portions, said walls being joined by a web and having a pair of inturned flanges depending from said walls at each side thereof, said walls, web and flanges defining a pair of converging channels, the improvement which comprises a pair of inturnedv flanges, partly dening one of said channels, depending from said walls at one side thereof and extending throughout the entire length of said channel from the narrow'endto the wide end and terminating in lower edges at the narrow end of the slider and upper edges at the wide end of the slider; a pair of flanges depending from said walls at the other side there- 29 thereon illustrating the engagement of the short flanges 30 of the slider 3i with' the link of one stringer, as at 32, and the engagement `of of, said anges extending from the narrow end of the slider and terminating short of the wide end, said rst andsecond named pairs of flanges cooperating upon lateral spreading of the string- 30 ers toV tilt the slider and lock the same against movement in one direction on the stringers by the longer flanges 33 with the llrk of the stringer,
as at 34. l
