9 Claims. (Cl. .Z4-205.14)

This invention relates to sliders as used on separable fastener devices to couple the Stringers of such devices by movement of the sliders along the stringers. More particularly, the invention deals with slider devices employing what I term a friction type of cam lock wherein the lock element is tensionally supported in engagement with the Stringer scoops or links and cammed out of engagement therewith in free movement of the slider along the stringers. The novel features of the invention will be best understood from the following descriptions 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;

andin which:

Fig. 1 is a side and sectional view of a slider made according to my invention.

Fig; 2 is an exploded perspective view of some of the slider parts to clearly illustrate the assemblage of the parts.

Fig. 3 is a side View of a modiiled form of hood or yoke I employ, on a reduced scale; and

Fig. 4 iS a View similar to Fig. 3 showing another modification.

In Figs. 1 and 2 of the drawing, I have shown a slider I8 comprising top and bottom walls II and I2 joined at one end of the slider by a connecting web I3, the walls II and I2 having inwardly directed side anges `I4 and; I5 respectively, by deiining the channel I6 of the slider. This Slider body, generally Speaking, is of more or less common structure, and is adaptable for use on separable fastener stringers, well known in this art, to couple and uncouple the scoops of the Stringers.

To diagrammatically illustrate the locking principles of the slider, I have indicated in Fig. 1 of the drawing two scoops I'I arranged in the channel I6 and engaged by lock elements I8 depending irom the sides of a lock member, hood or yoke I 9.

The hood or yoke I9 is in the form of an elongated box shaped enclosure having a top wall 20, end walls 2I and 22 and

side walls

23 and 24, note Fig. 1. The Vlocky elements I8 form downward extensions to the

side walls

23 and 24, as will clearly appear from a consideration of Figs. l and 2. The side walls have rcentrally thereof elongated and longitudinallyI extending apertures 25 adjacent the ends of which are in

clined apertures

26 and 21. For'sim'plicity in description, and byreason of lsin'iilalrityincon-h Struction, like Areferences are used'n identifying' I the

apertures

25, 26 and 2l on the opposed Side walls.

Extending upwardly from end portions ofthe top wall II are

lugs

28 and 29, having transverse apertures 38-3I for the reception of

rivet pins

32 and 33 for securing the yoke or hood I9 to the slider, the

pins

32 and 33 passing through the

apertures

26 and 21. In assembling the parts, a coil spring 34 is arranged between the end wall 22 of the yoke or hood and the lug 29, the spring.

normally urging the lock yoke to the right, as seen in Fig. 1, and downwardly (by reason of the inclination -of slots 26-21) thereby moving the lock elements I8 into firm engagement with the scoops I1. When the parts are assembled, it will appear that the Surface 35 of the lug 29 eX- tends to a point overlapping the elongated aperture 25 to form an abutment against which the inturned coupling ends 36 of a pull 37 are adapted to Strike in the operation of moving the slider to the right, as seen in Fig. 1, or in coup-ling a pair of stringers. However, in the operation of moving the slider in the opposite direction to uncouple the stringers, the ends 36 of the pull engage the ends 25 of the apertures 25 and draw the yoke or hood I9 outwardly by reason of the

cam apertures

26 and 21 riding on the pins 32-33, thus lifting the lock elements from engagement with the scoops II.

The top wall II of the slider has between the

lugs

28 and 29, elongated apertures 33 for freely receiving the lock elements I8 and permitting longitudinal movement of the yoke I9, as above described. It will be understood that upon release of the pull, the spring 34 will automatically return the yoke to bring the lock elements 8 into operative engagement with the scoops Il.

v In Fig. 3 of the drawing I have shown a slight modification in the form of yoke employed, the

yoke being designated by the reference I 9' and having lock elements I8 similar to the elements I8, apertures 25 similar to the apertures 25, apertures 26 similar to the aperture 2,6, and at 39 are shown apertures which differ from the apertures 2l in extending straight or parallel to the apertures 25" instead of inclined, as with the apertures 26'. With this construction, the camming action takes place primarily at the forward end of the yoke I9', whereas the rear end portion of the yoke slides back and forth in the elongated aperture 39.1 I

Y. In Fig. 4 of the drawing, I have shown another modication which differs from the structure shown in Figs. '1 and"2, simply in modifying the lock` elements I8" to the extent ofV having notches` or recesses 4D on the lower surfaces thereof. These notches or recesses are employed to provide a more positive engagement with the scoops in retaining the slider against movement along the stringers.

In Fig. 4, the yoke or hood is. identiiied by the reference character I9", and as the remaining structure `of this hood and yoke are the same, as the yoke I9, no further specific description is given.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
