' My invention relates 'to slide fasteners and particularly to means for preventing the slider sists of improved means carried by a stop' member at the end of the fastener for engagement with the slider to prevent unintended movement.

In illustra g my invention, I have shown a slide fastener of the same general locking detent 20 one of the top stop members of my inverttypeas that disclosed in the patent to Gidf eon Sundback, 1,219,881, March'20, 1917. Such a fastener comprises a pair of corded edge fabric stringers 11 and 12 having opposed series of fastener elements 13 and 14 clamped to their adjacent edges. The fastener; elements are successively brought together and interlocked by movement of a slider 15 in one direction and similarly the fastener elements are disengaged by movement of the slider in the opposite direction. A slider of the type illustrated comprises a pair of overl ing spaced wings on opposite sides of the astener stringers connected together by an integral wedging andspacing portion 16 and a pull device 17 issuitably connected to one side of the slider for actuating it along the stringers. A pair of stop members 18 and 19 are attached to the corded edges of the stringers 11 and 12 respectively at the upper ends of the series v I of fastener elements 13 and 14.- These stop members abut against each. other inside the In the accompanying drawing I haveslider preventing movement of the slider beyond the. end of the fastener element s. Each of the stop members comprises apiece of sheet metal blanked out and bent around the corded edge of the stringer and preferably before bending the stop member, a. is cut out and bent up from the middle portion of the stop element. The ends of these locking tongues or detents are turned inwardly toward the stringer as indicated at 21. As shown in Fig. 1 these locking tongues. project outwardly from the stringers and toward each other and when the slider is in a closed position, the wedging portion 16 engages over the locking tongues and 'it is thus held against accidental movement; I When it is desired to open the fastener the slider may be moved by the application of sufiicient force on the pull member 17.
- fication of the construction in Figs. 4 to 7 against the wedging portionv they are guided into the slider by theirinclined ends 21..
In the modification illustrated in Figs. 4 to 7, a pair of spring locking tongues 22 are cut out and bent away from each of the stop members so as to lie on opposite sides of the stringer instead of to project outwardly from its edge as in Figs. 1 to 3. The ends of these locking tongues are preferably bent inwardly as indicated at 23 similar to the portions 21 in Fig. 3. Suitable means are also formed in the slider for cooperation with these locking tongues when the slider reaches the upper end of its movement. Such means preferably takes the form of grooves 24 in the wings of the slider as best illustrated in Fig. 6 which shows the slider before it is bent to final form. The operation of the modified construction is substantially the same as the embodiment first described since the notches are curved and the engaging portions of the locking'tongues are inclined thus allowing automatic engagement and disengagement of the locking tongues upon an intended movement of the slider. In Fig. 8 there is illustrated a modiwhich will produce a positive locking effect. A square shoulder 25 is formed at the end of each of the locking tongues which engages in a square cornered recess 26 in the slider. Suitable means must be providedfor releasing the locking tongue in this modification and the release is preferably accomplished by means of a release pin 27 carriedby the pull member '17.
As. a result of my intended movement of the slider and consequent opening of the fastener. The locking is accomplished at the top stop of the firstener, thus insuring that the slider lock held in fully closed position. It will also be noted that my improved locking device is automatically controlled without any at-- tention whatever fromthe operator.
While I have in this applicationspecifically described three embodiments which my invention may assume in practice, it will be understood thatthese embodiments are merely for the purposes of illustration and description and that various other forms may be devised within the scope of my invention as defined in the appended claims. What I claim as my invention is; 1. In a slide fastener having 0 posed series of fastener elements, a sli er, movable along the same to control the interlocking thereof, said slider havi'nga wedging p0r-.
tion which enters between the fastener elements to disengage them when the slider is moved in one direction, and slider locking means for engagement with said wedging invention will be observed that a very simple form of locking. device has been provided for preventing unstringzrs portion to lock the slider against unintended movement in fastener opening direction.
2. In a slide fastener, a pair of flexible stringers, opposed series of fastener elements attached to the-adjacent longitudinal edges of said stringers, a slider movable along the stringers to control said fastener elements and a spring locking member projecting laterally in the plane of said stringers from the edge of one stringer to resilientlyengage said slider and prevent unintended movement of the same in fastener opening direc tion.
3. In a slide fastener, a pair of'flexible stringers, opposed series of fastener elements attached to the adjacent longitudinal edges of said stringers, a sheet metal member bent around one of said stringers, and a spring locking tongue out out and bent up from said sheet metal member for engagement with said slider to prevent its unintended cent the end of said series of fastener e ements, and a yielding locking detent projecting laterally from saidstop member in the plane of said stringers forengagement with said slider to prevent unintended movement of the same in fastener opening direction along said stringers.
5. In a slide fastener, a pair of flexible ments attached to the adjacent edges of said stringers, a .stop member attached to'each of said stringers adjacent the end of the series of elements, and a spring lockin tongue projecting laterally in the plane 0 said stringers from each of said stop members for resilient engagement with said slider to prevent uninten ed opening of the same.
