SLIDER for: SEPARABLE FASTENERS Filed Feb. 7; 1941 ATTORNEY Patented July 7, 1942 UNITED STATES PAT Ear, OFFICE v 7 2,288,780 L supra roe snmmnm msrmas Noble S. Williams, Stamford, Conn.,
United States Rubber, Company, N. Y., a corporation of New Jersey assignor to v New York,
Application February 7, 1941, Serial No. 377,791 6-Claims. ('01. 24-2055) This invention relates to an improved slider U forseparable -fasteners having an improved means for automatically locking the slider against unintentional movement in at least one direction along the fastener elements when a pull member associated therewith is released.
Heretofore sliders have been provided with means for automatically locking the slider on the fastener elements regardless of the particular position in which the pull member for operating the slider may be. when it is released. In such constructions the locking projection has been' movable with respect to thewings of the slider and has been actuated by a spring to hold it in locking engagement with the fastener elements, and this locking projection has been actuvated to its non-locking position by the pull member cooperating with a cam surface associated with the projection.
In accordance with the present invention the construction of the locking means is, simplified by fixing the locking projection to the top wing, of the slider, and a spring normally resiliently retaining the fastener elements in locking engagement with or in position to be engaged by wing of the slider. The locking projection is disengaged from the fastener elements by manuprojection when the projection is. in locking position with respect thereto;
Fig. 2 is a transverse cross-sectional view of the slider taken on line 2-2 of Fig. 1;
Fig. 3is a view similar to that in Fig. 1 but showing the locking projection disengaged from the fastener elements and in position to permit rearward movement of the slider when the pull is movedin the rearward direction;
Figs. 4- and 5 are cross-sectional views taken on lines l-4 and 5-5 respectively, in Fig. 1, and
showing the inner surfaces, respectively, of the top and bottom wings of the slider; and
Fig. 6 is a longitudinal cross-sectional view of a'modified form of the slider shown in Fig. 1.
Referring to the drawingin detail the slider I is provided with spaced top and bottom wings II and I2, respectively, and is operated by'a pull -member l3 having its end l4 slidably connected to a bail l which is struck up from the top wing H in the usual manner. The wings II and II V are provided with downwardly extending side the locking projection is secured to the bottom ally pulling the pull member so that the bottom wing of the slider and the spring carried there'- by are forced against the bottom surfaces of the fastener elements, which thereby depresses the spring and moves the locking projection relatively to the fastener elements and to a position out of engagement with the fastener elements.
When the pull is so' operated, the slider may bemoved along the fastener elements in a direction to disengage these elements'and open the fas-' When it is desired to be interlocked with one another as the slider The above objects and other advantages of this invention will be more readily understood by referring to the following description and the accompanying drawing, in which:
Fig. l is a longitudinal sectional view of a slider embodying this invention taken along line l-l of Fig. 2, and showing the cooperation between the' fastener elements and the locking flanges l6 whichform diverging channels l'l through which the rows of fastener elements I8 are adapted to slide relatively in respect to the slider. The slider is provided with the usual type of spreader l9 connecting the wings H and l2 at the forward end of the slider, which spreader in conjunction with the channels I! cause the fastener elements to be separated and is moved therealong.
The top' wing H of the slider is provided with a locking projection 20, which may be punched up from the wing material, or which may be formed of harder material brazed onto, or inserted in the wing. As "shown in Fig. 1, the locking projection 20 is positioned in respect to the fastener elements I8 so that it projects between the elements I 8, and such relationship between the elements and the projection is' normally maintained by a spring 2| having its front end 22 secured to the bottom wing 12 of the slider by arive't 23, or by other suitable means such "as welding or soldering. The spring 2l'is located in a groove 24, and its rear end is provided with an upwardly curved. portion 25 which is substantially opposite the locking projection 20 and resiliently contacts the fastener elements I8 so as to normally maintain the fastener elements in position to be en- I projection 20 when the gaged by the locking slider I0 is urged in either'direction. The extreme rear end 26 of .the spring 2! is curved downwith the bottomsurfaces of shown in Fig. 1, so that the terlocking fastener elements l8 and the sprin is depressed by pulling the pull member l3 upwardly away from the fastener'elements, and in order to move the slider i along the elements for disengaging same, the pull I3 is at the same time movedrearwardly in the direction in which it is inclined as shown in Fig. 3. When it is desired to close the fastener, that is interlock elements with one another, the end H of the pull I3 is moved forwardly along the bail l5 and into contact with the forward end of the bail. The forceexerted by the end H on the bail l5 may be either parallel to the plane of the top wing H, or the force may have a component away from the fastener elements IS in order to depress the spring 2i and move the locking projection from its locking position with respect to the fastener elements. It is. not necessary, however, to apply such component of force away from the elements, because th'e locking projection 20 is provided with a beveled surface 21 which projects downwardly and rearwardly from the top wing Ii, and the surface 21 will ride over the top edges of the fastener elements and permit the slider to be operated in the forward direction without such outward component of force being applied by the pull member IS.
A modified form of the invention is shown in said slider and pulling said bottom wing towards said fastener elements and thereby moving'said locking projection from said locking position in respect to fastener elements, and permitting said slider to be operated to separate the fastener elements.
2. A slider for separable fasteners having interlocking fastener elements comprising'a top and a bottom wing secured together at their front ends, a locking projection formed of harder material than the wing material fixed tothe rear end'of the top wing and extending towards said bottom wing, a spring fixed to said bottom -wing and adapted to normally retain the fas- Fig. 6, in which the bottom wing 28 is provided with a longitudinal groove lil'having a spring 30 secured therein by a rivet 3|. The spring 10 is adapted to resiliently contact with the bottom surface of the fastener elements l8 and normally retain the fastener elements in position to be engaged by the locking projection 32 affixed to the lower face of the top wing 33. The groove 29 has a greater depth at its rear end than at its front end so that the rear end 34 of the spring may be depressed into the groove a suincient distance to permit the locking projection to be moved out of its locking position in respect to the fastener elements IS without the end 34 contacting with the bottom of the groove 29 until the top surface of the curved portion 35 of the spring 30 is substantially flush with the top of the groove. The slider is provided with a pull, not shown, which a slidablyconnected to the bail 36 in a manner similar ated in the same manner as theslider of Fig. 1.
