JAM-FREE SLIDER WITH CONTROL THROAT Louis H. Morin, Bronx, N. Y.
Application June 2, 1955, Serial No. 512,610
13 Claims. (Cl. 24-20515) This invention relates to what are generally referred to as jam-free sliders for separable fastener stringers. More particularly, the invention deals with what 1 term a slider of this type having :a control element at the throat, which constantly maintains engagement of the stringer scoops at the throat area of the slider while, at the same time, providing relief, in the event of jamming, through a movable or yieldable back plate, which is recessed to receive and envelope the control element.
Still more particularly, the invention deals with a slider of the character described, wherein the control element is formed as an integral part of the top wall of the slider through an extending bar member joining the top wall through the integral web.
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:
Fig. 1 is :a longitudinal section through a complete slider, with parts of the construction shown in elevation and with part broken away.
Fig. 2 is a bottom plan view of the top wall part only of the slider body on an enlarged scale from the showing in Fig. 1.
Fig. 3 is a top perspective view of the back plate or bottom wall part of the slider, detached.
Fig. 4 is a perspective bottom view of the top wall part of the slider, detached; and
Fig. 5 is a partial section on the broken line 5-5 of Fig. 1.
My improved slider consists of two primary flanged wall parts, namely a top wall part it and a back or bottom wall part 11, these parts being shown in assembled relationship in Fig.1 of the drawing, in which figure, the
The downwardly extending web portion 21 of the top wall includes, in its upper surface, a socket 22 for receiving a coil spring 23, the latter seating in a recess 24 in the element 14 and serving to normally support the lock element in the operative position, shown in Fig. 1.
The pull 25 is indicated, in part, in Fig. 1 of the drawing and the pivot end 26 of the pull operates in a recessed portion 27 of the lock element in actuating said element against the action of the spring 23 to move the tooth end out of the channel 16 of the slider body.
Considering Fig. 2 of the drawing, it will appear that the wall 18 of the top wall'part 10 has, at the throat end portion 28, substantially parallel flanges 29, which flare outwardly and terminate at the widest diameter of the wall, as at 36.
Integral with the web 21 is a forwardly directed bar or bar member 31, which includes a pair of downwardly directed longitudinally spaced rivet members 32. Integral with the forward end portion of the bar 31 is a throat control element 33 including, at its sides, upwardly extending parallel flanges 34 which, in conjunction with the parallel portions of flanges 29, define the throat or what might be termed the mouth of the slider, which maintains the scoops in coupled relationship at this particular control point. That is to say, control of the scoops is maintained not only with respect to their height but also their width. The element 33 is in the form of a transverse narrow wall. The depth of the element 33 is substantially consistent with the length of the parallel portion of the flanges 29, so as to free the scoops at the beginning of the flared portion of the flanges, as will clearly appear from a consideration of Fig. 2 of the drawing.
It will be noted, from a consideration of Fig. 2 of the drawing, that the flanges 34 are substantially one-half the thickness of the flanges 29, so as to leave, outwardly of the flanges 34, room for reception of the parallel portions of flanges 35 of the bottom wall part 11, the flanges 35 fitting over and projecting beyond the flanges 34. In other words, aside from the formation of the deep recess 36 in the throat end portion of the bottom wall 11, the general contour of the flanges of the bottom wall would be the same as the flanges 29 of Fig. 2 of the drawing, the recess 36 being adapted to receive the element 33. The bottom wall 11 includes an elongated aperture 37 for reception of the bar 31, the bottom wall 11 being recessed, at its rear end, as seen at 33, substantially in lalinement with the side walls of the web 21, so as to clear any flare or roughened edge that may prevail on said side edges, thus dispensing with finishing operationsin assemblage of the slider wall parts.
From a consideration of Fig. 1 of the drawing, it will appear that, in assemblage of the wall parts, a substantially yoke-shaped spring 39 is arranged upon the bar 31 within an enlarged portion 37' of the aperture 37 and a retaining plate 40, substantially conforming to the contour of the aperture 37', but greater in length and Width than the bar 31 is secured in position by the rivets 32 and forms a backing for the spring 39 to normally support the bottom wall 11 in operative position. In the jam-free action of the slider, the bottom wall 11 is free to move downwardly against the action of the spring 39. In this latter action, it will be apparent that the control element 33 maintains the control throat or mouth of the slider, so as to maintain coupled relationship of the scoops at this particular localized area of the slider body. More specifically, when the slider encounters an obstruction which tends to move wall 11 and therefore flanges 35 away from wall 11 the flanges 34 on element 33 will still serve to control the scoops.
The element 33 is in the form of a crosshead at the end of the bar 31 and forms what might be termed a stabilizing member for stabilizing the wall part 11 in its movement relatively to the wall part 19, as well as to check movement of the wall part 11 toward the wall part 10 in maintaining normal spacing, which defines the channel 16.
