May 26, 1959 'L. H; MORINY 49 COMPRESSION BOTTOM STOPS FOR SEPARABLE FASTENER S'IIRINGERS Filed April 20, 1955 INVENTOR. LOU I5 H. MORIN ATTORNEY United States Patent COMPRESSION BOTTOM STOPS FOR SEPARABLE FASTENER STRINGERS Louis H. Morin, Bronx, N.Y.
Application April 20, 1955, Serial No. 502,577
Claims. (Cl. 24-205.11)
This invention relates to separable fastener stringers of the type employing a slider movable along stringer' The 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 suitable reference characters in each of the views and, in which: i I
Fig. l is a diagrammatic perspective and sectional view illustrating a bottom stop arranged upon a pair of string ers and indicating end scoops and .part of a slider.
Fig. 2 is a perspective view of a bottom stop, such as shown in Fig. 1, detached; and
Fig. 3 is a view, similar to Fig. 2, showing a modified form of construction.
With bottom stops of the type and kind under consideration, ditficulty has been experienced from the standpoint of maintaining alinement of the end scoops and applying strains to the slider walls by engagement of the walls proper with upwardly and downwardly protruding stop lugs on the bottom stops, the latter having a tendency to spread the slider walls.
Still further, provision of upwardly or upwardly and downwardly projecting stop lugs on the bottom stops creates an undesirable bulk in the overall thicknessof the bottom stop, which is undesirable in many uses of the fastener, particularly on various types and kinds of wearing apparel.
In overcoming these difiiculties and objectionable features, I have provided a bottom stop structure, wherein the overall thickness of the bottom stop is within the limits of the thickness of the scoops of the stringer. Further, the stop lugs are provided on opposed side edges of the bottom stop, so as to abut the flanged sides of the slider, thus dispensing with any stress or strain, tending to spread the slider walls. Still further, the bottom stop includes projecting lugs on upper and lower wall portions thereof to extend toward or engage the end scoop of the shorter stringer; whereas, the end scoop of the longer stringer is disposed in close proximity to or abuts the normal end wall of the bottom stop, thus maintaining the two end scoops in alinement and coupled relationship with each other to insure proper coupling engagement of the stringers in the operation of coupling the stringers. Further, the stop lugs are so positioned on the bottom stop as to permit the endof the slider to extend onto and house part of the wall structure ofthe bottom stop.
In Fig. 1 of the drawing, I have diagrammatically shown, at 10 and 11, the tapes of a pair of stringers hav- Ice ing beaded edges 12 and 13. At 14 I have shown one end scoop of a number of scoops applied to the beaded edge 12 of the tape 10 and at 15 is shown the end scoop of a series of scoops applied to the beaded edge 13 of the tape 11. At 16 and 17, I have shown part of the opposed walls of a slider 18, the walls having flanged sides 19 and 20, respectively, these flanged sides defining the channel or channels of the slider body and, at 21, I have indicated, in part, the forward end of the frog or connecting web of the slider, which joins the walls 16 and 17 at the wide end portion of the slider, as with other devices of this type and kind.
At 22 I have shown one of my improved bottom stops which comprises a die cast box-like body, defined by walls 23 and 24, joined and spaced by a central web 25, the web forming, at each side of the body, longitudinal channels 26 and 27 for receiving the beaded edges 12 and 13 of the tapes 10 and 11, as noted in Fig. 1 of the drawmg.-
The walls 23 and 24 have, atone side thereof, and in alinement with the channel 27, projecting lugs 28 which extend beyond the end surface 29 a suflicient distance to abut the end scoop 15, while also permitting the surface 29 to abut the end scoop '14, in the manner diagrammatically seen in Fig. 1 of the drawing.
In the construction shown in Figs. 1 and 2, the wall 23 only has laterally projecting side lugs 30 which are arranged in the plane of the wall 23, these lugs having right angle front surfaces 31 and rounded rear surfaces 32.
' In moulding the end stops 22, it will be understood that the channels 26 and 2'7 are made sufliciently large to snugly, but freely, receive the beaded edges 12, 13, after which, pressure is applied to the walls 23 and 24 to compress the web 25 and to move these walls toward each other in securely crimping the end s'top upon the beaded edges 12 and 13. This is accomplished with the end stop in abutting engagement with the end scoops 14 and 15, in the manner illustrated in Fig. l of the drawing.
In Fig. 3 of the drawing, I-have shown a slight modification in the structure of the end stop and, for this reason, like prime references will indicate corresponding parts, the end stop being designated by the reference character 22, the walls at 23', 24, the web at 25, the channels at 26', 27', the projecting lugs at 28, the end surfaces at 29' and the laterally projecting lugs at 30'. The lugs 30' are of the' same structure as the lugs 30 and, therefore, will not be further'described.
In the structure shown in Fig. 3, the bottomv wall has similar laterally projecting lugs 33 arranged in alinement with the lugs 30' so as to establish abutting engagement with the flanges 20 of the slider wall 17. v
Considering Fig. l of'the drawing, it will" be apparent that, when the slider 18 is in abutting engagement with the lugs 30, as diagrammatically seen in Fig. 1 of the drawing, the contracted end portion 18 of the slider overlies the walls 23 and 24 of the bottom stop inwardly of the lugs 30. It will, thus, be apparent that, by virtue of this arrangement, the frog 21 does not exert any direct strain upon the end scoops 14 and 15, tending to separate said scoops. In other words, these scoops are maintained in coupled relationship at all times, thus inl thickness of the scoops on the stringers, thus producing 3 a smooth surface on the resulting fastener which will adapt the same for comfortable use upon the various types and kinds of wearing apparel.
Having fully described my invention, what I claim as new and desire to secure by Letters ,Patent is: l.
