body is provided on its exposed face with a rib l.

The rib illustrated isformed with a transverse opening having the opposite end walls 9 and il, an outer wall 13, and an inner wall l formed by the adjacent exposed face of the slide body.

For moving the slide body in each of opposite directions the same is provided with a handle,

, preferably formed of a bent wire to provideopposite legs]? and E9. The end portion of the leg i'l as shown, has a portion 28 extending transversely of the slide body through the opening in the rib if of the slide body; while the leg as has a corresponding portion 23 also extending through Fig. lO'is a fragment of the slide and assembled handle according to Fig. 9, corresponding to a section on the line 2 -2 of Fig. 1;

Fig. 12 is a plan of a further modified form of slide and assembled fastener;

Figs. 13, 1'4, 15 and 16 are sections on the lines 13-13, l4--l4, I5-I5 and IG-IS of Fig. 12;

Fig. 17 is a perspective of a detail employed in the construction according to Figs. 12 to 16; and

Fig. 18 illustrates a still further modified form of slide and assembled fastener.

Referring to the drawings, which for convenience of illustration shows the device on a much enlarged scale, the multiple fastener comprises a series of spaced cooperating fastener elements l.of any usual or suitable kind secured to the edge portions of the webs 3.

The slide body 5, which maybe of metal or molded-material corresponding to the material of the fastener elements, may, as usual, be moved m one direction to iause the fastener elements on the two webs to engage so as to close the fastener, and may be moved in the opposite direction to cause the fastener elements to disengage so'as to open the fastener. The slide body, like the fastener elements, may in its general aspects be of'any suitable or convenient construction.

As shown in Figs. 1 and 2, the improved slide this opening. The free end part of the portion it of the leg ll, as illustrated, is bent to form a portion zoiextending toward the free end of a handle, this portion 25 being bent 'to provide a laterally extending pin 27 adapted to project through an opening 25 iri'the slide body so as to project into the spaces between adjacent fast'enerelements I, as shownin Fig. 2.

In the above construction the handle may be swung about the portions 2! and 23 thereof as a pivot to retract the'locking member constituted by the pin 2l from engagement with the fas-' tener elements so that the. slide body may be moved in either of opposite directions to open or close the fastener. It will be observed that when the parts arein the position shown by Fig. 2 the slide body cannot move in fastener opening direction as any tendency for it to do so will be prevented by the pin. As the pivot. for the handle constituted by the portions 2| and 23 thereof is above the pin in the position of parts shown by Fig. 2 any tendency of the slide body to move in fastener opening direction will cause the pin to be urged into locking position when it is contacted by the lowermost fastener element of the pair of fastener elements between which it lies. Accidental movement of the slide body in fastener closing direction would not be prevented with the parts in the position shown by Fig. 2, but it is not necessary ordinarily to prevent such movement. 1

Itwill be observed that the size of the opening in the rib I in which the handle is pivoted provides a certain amount oflost motion between the handle and the sllde body longitudinally of the latter, which arrangement is preferable to 1 -tion of the opening, as viewed in Fig. 2, of such dimension transverse to the direction oi movement of the slide as will insure the pin being held in looking engagement with the fastener elements when the parts are in the position shown by Fig. 2.

Referring to the diagrams shown by Figs. 4, 5, 6 and 7, it will be observed that when the handle is swung from its position shown by Fig. 4, which corresponds to its position shown by Fig. 2, to that; shown by Fig. 5, further swinging of the handle to position it to move the fastener in closing direction tends to be prevented by'the portion" 23 of the handle contacting the outer wall l3 of the opening in the rib 1 of the slide, the portion 2! of the handle under these conditions contacting the walls 9 and I5 of the opening. However, further movement of the handle progressively into its position shown by Figs. 6 and '7 will cause relative movement be-' tween the relatively resilient legs I! of the handie, this movement gradually increasing as the handle is moved from its position shown by Fig.

5 to those of Figs. 6 and '7. This relative movement between the legs of the handle, resulting in the leg l9 swinging a greater angular distance than the leg I'I, causes the handle when released, say after the fastener is closed with the handle in the position shown by Fig. '7, to snap back and move into its position shown by Fig. 4, in which position the slide lock is engaged.

The wire of which the handle is formed is preferably of such length as to permit the desired degree of relative resiliency between the legs, and is bent, as shown in Fig. 1, for example, to make it of convenient shape and size. This result maybe secured by bending the wire into various other shapes, for exampl that shown by Fig. 8, in which the legs 3| and 33, corresponding to the legs i1 and I9 of thehandie of Fig. 1, have a sinuous shape. Preferably, but not necessarily, the two legs are connected by a bridge piece 35 to prevent accidental spreading of the legs. Preferably the bridge piece is loosely connected to the legs I 9, as clearly indicated in Fig. 11. As so constructed the legs may be sprung sumciently to permit the handle shown by Fig. '1 ,or that shown by Fig. 8 may be formed to have the shape indicated by Fig. 9 before the portions 2| and 23 are inserted in the opening of the rib 1.' A shown in Fig. 9,-

the two legs 31 and 39, corresponding to the legs I] and IQ of Fig. 1, are so formed that they are at an angle to each other before the portions 2| and 23 thereof are inserted in the opening in the rib 1 of the slide body. When inserted in that opening the parts assume the position shown in Fig. 10, in which position the portion 23 of the portions 2| and 23 of the prefabricated handle to be inserted in the opening in the rib "I.

It will be observed in the modifications above described that the handle can be moved from its position shown by Fig. 4 to that shown by Fig. 5 before the relative movement between the relative resilient legs I 'I and I9 occurs. In other words, when so constructed the normal. position of the handle is a position in which the handle has considerable lost anguiar motion. The angle through which the handle may be turned from its position shown in Fig. 2 before distortion occurs between thilegs to cause it to be urged back to its normal position may be varied by increasing or decreasing the distance between the walls I3 and I5 of the opening, as will be obvious from Fig. 5, and in many instances it has been found that satisfactory results will be secured when the portion 23 of the handle does not contact the position shown in Fig. 2 about 30 to 45 degrees 'or other angle considerably less than 90 detained in its position shown by Fig. 2, either the wall l3 until the handle has been swung from its leg 31 yieldingly bears against the outer wall 4| to pull the slide in fastener closing direction the portions 2| and 23 of the handle will move to the upper end of the opcning, as shown in Fig. 10, and will coact with the wall of that opening, in exactly the sameway as the handle according to Figs. 1 and 2 coacts with the walls of the opening shown in Figs. 5, 6 and 7, to cause the leg 31.0! the handle of Fig. 10 to swing a lesser distance than the leg 39 thereof and distort the handle out of its position shownin Fig. 10, so that when the operator releases the handle, say when it is in the position corresponding to Fig. 7, it will snap back into its position shown by Fig. 10. v

The length ofthe wire forming the handle and the resiliency of the latter may be much increased for a given length of handle by employing the construction according to Figs. 12 to 18. In this construction the hinge portions 43 and 45 which extend through the opening 41 of the rib I both leave the same side of that opening to form the body of the handle. As shown in Fig. 12, the wire at the left hand end of the end portion 43 is bent to form a leg portion 49 extending longitudinally of thejaster so as to form part of the handle. The wire at the end of this length 49 has a return bend 5|, 53, extending the leg to the opposite side of the longitudinal axis of the slide body, the length 53 being symmetrical with the length 49. The length- 53 near the rib 1 is this reverse bend the length 51 is bent back upon itself at a reverse bend 62 to form a length 53 which terminates in the pin 21.

For closing the space between the reverse bends 54 and 62, and for keeping them in alignment, a bridge piece 61 extends between the two sides of the handle. This bridge piece at one end is bent to form a portion 59 extending about the lengths of wires 49 and 59 at o ii side of .the handle, as shown in Fig.-15, these wires being confined loosely by the bridge piece. At its opposite end the bridge piece is bent toform portions 1| extending into the spaces between the pairs of wires 5|, 63 and 53, 55 so that the bridge piece will be maintained in' proper position longitu- 2,270,984 dinally of the handle, the portions H loosely connecting the bridge piece to the lengths of wires 63 and 53.

As illustrated in Fig. 14, the opening 41 in the rib i may have its outer surface 13 tapered in such way as to provide a larger opening in a vertical direction at the left hand side of the rib as viewed in Figs. 12 and 14 than at the opposite side. This acts to form a better pivot at the ends of the wire portions 43 and 45 adjacent the pin 2'! so that a better operation of the latter is secured, and when the handle is swung into fastener closing direction causes the left hand end of the wire portion 45 to be distorted more than the right hand end as viewed in Fig. 12, this causing a twisting as well as a lateral displacement of the wire length 59 and adding to the resiliency of the device.

5. A slide according to claim 1 in which one of the relatively resilient parts of the handle directly carries the ,locking means.

6. A slide according to claim 1 in whichone of the relatively resilient parts of the handle directly carries the locking means, saidparts each having a portion positioned transverse to the di- In making the device according to Fig. 12 the wire forming the handle may be bent to the shape shown, and the portion comprising the pin 21 and lengths Bland 63 may be passed through the opening 41 with the handle turned at right angles to the slide, thelengths of the other portions being such as to afford sufilcient resiliency to permit the necessary springing of the parts during this operation. After the handle is in place the bridge piece 61 may beapplied.

The scheme of bending the wire forming the handle according to Fig. 12 may be employed in other shapes of handle as, 'for example, that shown in Fig. 18, in which thereis formed in the opening between the wire lengths 15,; TI and 19, 8| an internal length of wire 83 bent to such shape that the handle is so formed as to provide a preferred gripping means for engagement with the'fingers. 1
