TORNEY United States Patent AUTOMATIC SPRING PIN LOCK SLIDER OPERATABLE FROM BOTH SIDES Lonis H. Morin, Bronx, N. Y.

Application March 29,1954, Serial No. 419,241

16 Claims. (Cl. 24-205.14)

This invention relates-to sliders for use in connection with separable fastenerstringers to coupleand uncouple the stringers. More particularly, the invention deals with sliders of this type and kind, having means on) opposed surfaces of the slider for actuating the slider. and, particularly, in movement of the lock elem'entof the. slider into inoperative position for movement of thelslider along the stringers.

Still more particularly, the invention deals with a lock slideremploying a spring actuated lock element for automatically moving the lock element into operative position.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, inwhich certain embodiments of the invention areidsclosed and, in. which, the separate parts are designatedby suitable reference charactersin each of the views and, in which:

Fig. 1 is a large face view of.one;side of one form of slider which I employ, illustrating the lock element of the slider in operative position.

Fig. 2 is a section on the irregular line 2-2 of Fig. 1 with part ofthe constructionshown in elevation and with other parts broken away.

Fig. 3 is a view, similarto Fig. 1, of the opposed side of the slideron a materially .reduced scale.

Fig. 4 is a view, similar to Fig. 2, on a reduced scale showing a modified form of=construction and showing onlya part of the .sliderstructure.

Fig. 5 is a perspective view ofa modified-form of slider which I employ;

Fig. 6 is a view, similar to Fig. 1, showing only part of the slider and showing a modification, the view looking in the direction of the arrow 6 of .Fig. 8.

Fig. 7 is a view, similar to Fig. 6, but looking in the direction of thearrow' 7 of Fig. 8; and

Fig. 8 is a section on'the line 8-8 of Fig. 7 with part of the construction shown in elevation.

In Figs. 1 to 3,.inclusive, I have shown one form of automatic spring pin lock slider which I employ, having means at opposed side surfaces of the slider controlling operation of the spring pin lock mechanism employed. In these figures," 10 represents a slider body defined by spaced walls Hand 12 integrally joined at the wide end of the slider in a connectingweb 13, as clearly noted in Fig. 2 of the drawing. The walls 11 and 12 have inwardly directed side flanges Hand 15, respectively, which define the channel 16-of' the slider body, the web 13 dividing the channel at the wide end of the body, as with other devices of this type. and kind.

The wall 11 has a pair ofoutwardly extending bearings 17, note Fig. 1, in which'is mounted. a pivot pin 18,- upon which a pull 19ais pivoted. The pull 19, around the pin 18, has a hood 20 with a sufficiently large recess 21 to receive a coil spring 22, the latter being mounted on the pin 18; One end 23 .of the spring seats in a recess on the inner surface 24 of the pull 19; whereas, the other end 25 of .the spring tits. in an aperture 26 in the wall 11, as clearly noted in Fig. 2 of, the drawing. serves to normally support a projecting pin or lock ele- The spring 22:

ment 27 of the pull 19 in operative position, that is to say, to extend into the channel 16 through an aperture 28 in the wall 11 of the slider.

The wall 11 of the slider also has another transverse recess 29, in which the hood 21] is adapted to extend when the pull 19 is swung outwardly into operatable position, in which position the lock element 27 is withdrawn from the channel 16. The hood 20 has an extending wall 30 at its free edge, which extends into the recess 29, as clearly noted in Fig. 2 of the'drawing.

The web 13 of the slider has a transverse aperture 31, in which a pin 32 is mounted. The pin 32, outwardly of the wall 12, has an elongated fingerpiece 33, which extends longitudinally of the wall within the environment thereof, as noted in Fig. 3 of the drawing. The fingerpiece 33 facilitates rotation of the pin 32 for actuation of the pull 19 in movement thereof into position withdrawing the lock element 27 from the channel 16. This operation is accomplished through the medium of a double cam 34 mounted on the other square end 35 of the pin'32. The cam 34 is generally of the contour seen in Fig. 1 of the drawing andha'srounded ends 36 and 37, which are adapted to operatively engage the wall 30.

The wall 11 has another recess 38 opening into the recess 29 and the cam 34 operates in the recess 38, as clearly noted in .Fig. 2 of the drawing.

From this structure, it will appear that, by rotating the finger piece 33 in either direction, as indicated by the arrows of Fig. 3, the rounded ends 36 and 37 of the cam 34- will be correspondingly rotated to move in the directions of the arrows indicated in Fig. 1 in applying pressure to the wall 30 to swing the pull 19 outwardly against the action of the spring 22 in Withdrawing. the lock element 27 from the channel 16 of the slider. The fingerpiece 33, as well as the pull 19, may be utilized in operat ing the slider in both directions along separable fastener stringers in coupling and uncoupling the same.

In Fig. 4 of the drawing, I have shown a slight modification of the structure shown in Figs. 1 to 3, wherein, instead of using a solid elongated fingerpiece 33, a loop 33' is employed and constitutes part of one end of a pin 32, similar to the pin 32, 12' representing a slider wall, similar to the .wall 12. With the elongated loop 33 is coupled a fingerpiece ring or other member 39, which can be utilized inrotation of the pin 32, as well as in moving the slider 10' along a pair of stringers. slight modification, the structure of the slider 10'. will be the same as the slider 10 shown in Figs. 1 to 3, inclusive.

In Fig. 5 of the drawing, I have shown at 16" another slider, similar to the slider 10, and at 33. I have shown another form of ring or loop mounted on the end of a pin 32", similar to thepin 32. In Fig. 5 of the drawing, the ring or loop 33" extends transversely of the wide end of the slider and coupled therewith is one looped end 40 of a fingerpiece strap 41, the other end of the strap also preferably having a looped end 42, as clearly noted in the drawing. Here again, the slider is actuated in the same manner as the slider shown in Figs. 1 to 3, as well as in Fig. 4 of the drawing.

In Figs. 6 to 8, inclusive, I have shown another form of slider construction and, referring to Fig. 8, 43 shows a slider body having spaced walls 44 and 45, generally similar to the walls 11 and 12,.andjoined at one end by a connecting web 46, apertured, as seen at 47, to receive a transverse pin 48. The pin 48 differs from the pin 32 in having two square ends 49 and 59, on which are mounted single cams 51 and 52, respectively.

At 53 and 54 are shown two pulls, substantially the same as the pull 19, both pulls being actuatedbysprings 55 and 56, respectively. The pull 53 is substantially identical with the pull 19- in having. a lock element 57 extending into the slider body, similar to the element 27;

Aside from this whereas, the pull 54 does not have the lock element. Further, the pull 54 has a modified form of hood 58 at its pivot end, the hood 58 having a projecting cam surface 59, note Fig. 7, for operatively engaging an offset finger portion 60 on the cam 52. In other Words, when the pull 54 is moved into raised position with respect to the wall 45, the cam surface 59 will actuate the cam 52 in the direction of the arrow 61, Fig. 7, which, in turn, will rotate the cam 51 in the direction of the arrow 62, Fig. 6, to cause the pull 53 to be swung into outward or raised position with respect to the wall 44 in withdrawing the lock element 57 from operative position in the slider body.

In connection with the operation of the slider shown in Figs. 6 to 8, inclusive, it will be apparent that, when the pull 53 is manually operated and swung into the outward position in retracting the lock element 57, no action is contributed to the opposing pull 54; in other words, the pull 53 simply performs its normal function and the pull 54 simply remains idle.

It will be apparent that the slider wall 45 has a recess 63 for reception of the hood 58 when the pull 54 is moved into raised position. As the structure of the wall 44 of the slider body 43 is identical with the recessing of the wall 11 of the slider 10, no further detailed description of this part of the slider structure is deemed to be necessary.

Considering Fig. 8 of the drawing, it will be seen that the cams 51 and 52 operate in recesses 64 and 65 in opposed surfaces of the slider body, these recesses being also noted in Figs. 6 and 7 of the drawing, both recesses being of a contour generally conforming to the contour of the cams employed. In this respect, the recess 64 differs from the contour of the recess 38 of Fig. 1 of the drawing.

With the different forms of slider structures shown, the slider may be operated from both sides of the slider body and, in both directions, the lock element of the slider can be moved into inoperative position to free the slider for movement along the stringers. In all forms the pull having the lock pin or element may be grasped and moved without affecting the operating means on the opposite slider wall.
