Description
June 16, J FORSTER SEPARABLE FASTENER Filed Aug. 10, 1934 F429. 6. 1 43.7. Q IIIH INVENTOR J'OHN .5. FORSTER AT RN EY ing fastener that shall embody Patented June 16, 1936 UNITED STATES PATENT OFFICE 6Claims.
My invention relates to sliding fasteners and particularly to stop and closing means for the upper ends thereof.
An object of my invention is to provide a slidsimple means to ensure that the entire length of the fastener shall be securely closed.
Another object of my invention is to provide a separable fastener having stop members at the upper end that shall permit the greater portion of the slider to travel beyond the topmost locking members in the closing operation and to move smoothly and evenly onto the locking elements during the opening movement.
Another object of my invention is to provide a pair of upper stop members that shall cooperate in one sequence with a slider during the closing movement and in the reverse sequence during the opening movement.
Another object of my invention is to-provide a pair of upper stop members so shaped and located as to constitute, in effect, a continuation of the locking elements alternately secured to the pair of stringers.
Other objects of my invention will either be pointed out specifically hereinafter or will be apparent from a description of a device embodying my invention.
In practicing my invention, I provide, in addition to the usual series of locking elements secured in alternation to a pair of stringers, a pair of upper stop members, of substantially elbow or arcuate shape, having outer surfaces adapted to be engaged by the inner faces of outer portions of the slider in a certain sequence, and hav-, ing also inner surfaces adapted to be engaged by the internal cam of the slider in the reverse sequence. The longitudinal extent of the two stop members is slightly diflerent and they are located, one on each stringer, in an alternation continuing that of the locking elements.
In the drawing,
Figure 1 is a view, mainly in front elevation, with the slider shown in section, of a device embodving my invention,
' Fig. 2 is a view, in lateral section therethrough, taken on the line II-II of Fig. 1, I Fig. 3 is a top plan view similar to Fig. 1 of the drawing, but showing the fastener in a slightly opened position,

Fig. 8 is a view in side elevation of the stop 5'- member shown in Fig. '7, and,
Fig. 9 is a view in end elevation of the two members shown in Figs. 5 and 7.
As has already been stated, my invention is related to a specific form of stop means for the 10' upper end of a separable fastener and I- have therefore shown only a left hand stringer ll having a bead l3 at its right hand edge and a second stringer [5 having a bead at its left hand edge. A plurality of locking elements IQ of any suitable or desired construction usual in this art are located in alternation on the beads l3 and I1 respectively. It is to be understood that the locking elements l9 severally include any desired form of bifurcated member which is provided with an inner enlarged opening 2|, the bead I3 or I1, as the case may be, being adapted to be located within this enlarged opening 2|, so that when the bifurcated member has been placed in proper operative position on the stringer I5 and the bead thereon, the locking element will be held securely thereon so that, other conditions being provided, the separable fastener can be easily and properly actuated by a slider 23. This slider is of a kind also well known in the art and includes an outer portion 25 and an inner portion 21, each having laterally-extending edge or flange portions 29 facing each other and spaced slightly apart so that the stringer may move' between such edges, in a manner well known in the art. The slider has a substantially Y-shaped opening internally thereof constituted more particularly by a central cam 3| having substantially the lateral section shown in Figs. 1, 3, and 4 of the drawing, in combination with the outwardly extending walls 33 on .the right hand side (as seen in Figs. 1, 3 and 4 of the drawing), and the outwardly extending walls 35 on the left hand side, each of which is con stituted by the flanges 29 and which have the inner operating or actuating surface 31 and 39 respectively, which actuating surfaces extend at a proper angle relatively to the longitudinal axis of the fastener.
Any desired number of the locking elements 19 may be provided in accordance with the desired length of the opening which is to be served by the separable fastener. I have not shown any lower stop members, although it is to be understood that any suitable or desired type of such lower stop members is to be provided, as is usual in such devices.
I will now describe the particular part of the separable fastener which embodies my invention. I provide a first upper stop member 4| which is of elbow or of substantially arcuate shape longitudinally of the fastener and which is of substantially U-shape in lateral section, as will be seen more particularly fromFig. 9 of the drawing. This stop member is relatively long and has an outer face or surface 43 which extends angularly relatively to the longitudinal axis of the fastener at substantially the same angle as does the actuating surface 3! of portions 33 of the slider. Member 4| is further provided with an inner actuating face 45 which extends substantially-parallel to the outer face 43 thereof.
I provide further a second stop member 41 also of elbow or of arcuate shape in plan, and of substantially U-shape in lateral section, this second stop member being somewhat shorter, in a longitudinal direction, than stop member 4|. It is provided with an outer actuating surface 49 whose radius of curvature is less than that of face 43 of member 4|. Member 41 is further provided with an inner surface 5| and particularly cam surface 53 adjacent its lower end, which cam surface is adapted to be engaged by one operating surface of the central cam 3|, as will be hereinafter described in detail.
The two stop members 4| and 4'! are secured respectively to the right hand stringer l5 and to the left hand stringer II in such position thereon that the lower end of stop member 4| is located a proper distance above the uppermost locking element i9 on stringer while stop member 4'! has its lower end located above the lower end of stop member 4|, the upper ends of the two stop members being located at substan tially the same vertical position relatively to each other, as will be seen more particularly by reference to Fig. l of the drawing.
As is well known in the art, separable fasteners of this kind depend for their easy and smooth operation upon the principle that the operating surface shall engage one locking element after the other, particularly in the opening movement, to force the uppermost locking element still in engagement with a subjacent locking element outwardly away from that element in order to break the interlock heretofore efiectiv'e between the two elements. It had heretofore been impossible to move the slider on a separable fastener of this kind upwardly on the locking elements so far that the upper ends of the stringers would extend parallel to each other and would lie closely adjacent to each other, a condition which was necessary to effect full closure of the fastener along its entire length.
same time and force them toward each other,'
to thereby cause approaching movement of the stringers l5 and ii into substantial parallelism, so that the fastener is in completely closed position. It will be noted particularly that the greater portion of the slider 23 has been moved beyond the locking elements IS, a condition which was impossible heretofore.
Referring now to Fig. 3 of the drawing, it will be noted that the left hand side of central cam 3| is in operative engagement with the inner 5 cam surface 53 of member 41 and has forced stop member 41 to the left or away from the right hand stringer IS. The uppermost locking element is has also been turned slightly upwardly so that it is already out of interlocking engage- 10 ment with the next lower locking element, which is secured to stringer l5. This position of the slider is the one which occurs shortly after beginning a downward or opening movement of the slider 23.
If the slider 25 is now moved still further downwardly the right hand actuating surface of central cam 3| engages the inner cam surface 45 of stop member 4| and forces it to the right whereby the uppermost locking element is on stringer |5 will be turned slightly in a clockwise direction to thereby release it from its initial interlocked relation with the subjacent locking element secured to stringer Further downward or opening movement of the slider, will cause the central cam 3| to come into engagement with the locking elements i9, as is shown in Fig. 4 of the drawing, and I have found it possible, by the use of the stop members hereinbefore described to effect easy and smooth opening of a separable fastener of this general kind.
A brief description of the fundamental principles underlying the design and operation of my improved stop members will make clear the reasons for the smooth operation of a separable fastener embodying these stop members. It is to be noted particularly that the lower end of stop member 4| is located on the right hand stringer l5, in superposed position above the uppermostlocking element I9, which in the device shown in the drawing, is located on the right hand stringer. In other words, the lowermost portion of one of the two stop members is located in a continuing alternation on the stringers. The lower end of the other stop member 41 is 5 located at a. slightly greater distance on stringer H and it also continues the sequential alternation of the locking elements i9, continued in part by the lower end of stop member 4|,
I have found it possible to move the slider, at
least for the greater portion of its length, out of engagement with the locking elements on the stringers and still be able to move the slider downwardly, when desired, to effect opening of the fastener, without any jamming or looking thereof relatively to the locking elements.
Various modifications may be made in the device embodying my invention without departing from the spirit and scope thereof, and I desire therefore, that only such limitations shall be placed thereon as are imposed by the prior art or are set forth in the appended claims.
