To all whom it may concern:
Be it known that I, GIDEON SUNDBAGK, a subject of the King of Sweden, and resident of Meadville in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improv ments in Separable Fastener-Sliders, of which the following is a specification.
This invention relates to separable fastener sliders and has for its object to provide a novel form of slider which can be cheaply manufactured, and which will have increased factors of strength and facility of operation, as compared with sliders heretofore constructed.
A separable fastener of the type to which this invention relates-is illustrated in my Patent #1,219,881, issued March 20, 1917. The slider shown in this patent is provided with relatively widely divergent curved channels and is operated to close the fastener by means of a pull device located at the upper end, curvature of the slider channels being such as to cause the slider to open the fastener when the edges of the stringers carrying the interlocking members are pulled apart. The slider itself is composed of a single stamping doubled over and connected b a rivet passed through a stifl'enin mem er, and gives very satisfactor resu ts when used on fasteners intended for relatively light use. When this fastener is applied to closures involvin unusual strains and excessive wear, the sli er tends to distort owing to thewedgin action of the interlocking members. hen it is at tempted to apply this type of fastener to closures having stifi edges, such for example as tends, automobile and other vehicle curtains, boned edge corsets, etc., it has been found that the slider must not only be so constructed as to resist the spreading action of the interlockin members under heavy strains, but the sli er must. also be capable of being conveniently and positively operated in' both directions from either side. This is not only because the stifi edges above referred to are frequently too stifi to permit bein pulled apart to open the fastener, but also cause it 1s desirable to so construct the fastener that it will stay looked under lateral tension without necessitating the aux- 1l1ary fastening such as a hook and eye, buttop or the like heretofore employed with wide angle curved sliders in order to prevent accidental openin In a tent or curtam closure for examp e, which must somet mes be operated from one side and sometimes from the other, in either direction, the prov sion of an operating device for each side is not only objectionable because of duplication, but is liable to be confusing to the operator.
The particular object of this invention is to provide a slider which will not spread when subjected to a heavy strain, and which can be actuated positively in both directions from either side by a single pull, thus re- %llll'lllg the operator simply to gras the ree end of the operating evice an pull the slider in one direction to close the fastener and in the opposite direction to open it.

The fastener body is composed of a stampthe ing having flat wings 1, 1 provided with turned edges 2, 2 turned in at a' right angle as shown in Fig. 4, or at an acute angle as shown in Fig. 5. The inturned edges 2 on the wings 1 are straight, but at an acute angle to each other, and end in straight portions 3 forming channels through which the interlocking members pass. At each end of the win 1 is an upturned lu 4 having a perforatlon 5, and connecting the wings 1 1s a neck 6 having a slot 7.. Thls blank is doubled over on itself so as to bring the inturned wings 2 adjacent and in registry with each other to form diverging channels, and havin the lugs 4 projectin outwardly on each %ace of the slider. he wings thus form a Y-shaped assage through which the interlocking mem ers pass.
The stifi'ening yoke shown in Figs. 8, 9, and 10 is first stam ed from sheet metal in the form shown in igs. 8 and 9, and comprises a body 9 having flanges 10 around the edge, a slot 11 in the mid le formmg narrow necks 12, and a key slot 13 near each end. This blank is then don-bled over so as to bring thefiat'faces back to back with the slots 1 fstering. as shown in Fig. 10.
The n 2 new orm narrow projections or poin which fit 1n the perforations 5 1n the-lu gs The yoke member shown in Figs. 10, and made by doubling over the blank shown in Figs. 8 and 9 thus consists generally of two channeled or flanged sections placed back to back, and having generally the shape o1? the letter U. The doubled over slider blank is also similar to the letter U, having the slot 7 at the bend, the slot 7 being of width just sutlicient to receive the thicknesses of the oke body 9. The yoke is slipped on to oub'led slider until itis stopped by reaching thebottoni ofthe'slot 7, at whic time thei 141 of thefyoke have passed through t a l'perforatedlu 4 of the slider The slider isthus he d rigidly against sprcadinby means extending the entire length 0 the slider and interlocked with the lower end of the slider. The yoke is held against sidewise or lateral shifting by sliding down in the slot 7, and it only remains'to lock the yoke against withdrawal.
This is-done by means of a key or pin '17 comprised of. a' narrow flat strip which is passed through the slots-13 immediate] under-the bent neck 6 of the slider,'thus olding the entire device assembled. The ends of the key 17 are bent down on each side as shown in F'i 2 and form guidin surfaces for the interlockin stringer memrs.
In addition to the function of stiifening the entire slider, the yoke has the additional function of forming a convenient means for attachingthe pull 18. This consists of a stamping having inturned lugs 19 separated naoaeoo sufiiciently to receive the combined thicknesS of the two yoke flanges 10 seen in Fig. 1. In assembling, the all lugs 19 are shd under the flanges 10 oi the oke, and then the yoke is interlocked and keyed to the slider. The single pull device 18 can then travel around on either side of the slider and when the cord 19 is pulled will positively actuate the slider in either direction, on either side. This is of considerable advantage in a device of this character, both because there is only one possible device for the operator to .pull and also becausethe pull will necessarily be exerted longitudinally of the slider, without catching at an intermediate or dead center point.
As shown in Fig. 4, the jaw ends 20 of the interlocking members 21 are fastened on a stringer 22, and the jaw ends 20 are rovided with right angled rear edges w 'c-h coiiperate with the ri ht angle edges 2 of the slider without prod action on the slider. This is an important feature in fasteners intended'for heavy servucing any spreading ice, because heretofore the interlocking members whenever subjected to heavy strain, either in fastening or unfastening, tended'to spread the slider and render the entire device inoperative. B the e06 ration herein dscribed of the .sti ened sli er and the jaw members engaging with the intumed edges, such difficulties are entirely obviated.
In Fig. 5, a further modification is shown in which the jaw members have acute angled corners 24 interlocking with acute angled edges 25 of the slider and still further reducmg any spreading action of.the interlocking members in the slider.
In Figs. 11, 12 and 13 a modified slider construction is shown, wherein the slider wings 30 are provided-with oflset tongues 31 on each side.
The yoke consists substanto receive the oifset tongues 31 of the slider wings, the base of the tube being offset inwardly on each side as at 34 so as to continue the inner surface of the slider. The tube also has side wings 35 which are inturned to close the slider 36. The base bf the tube has perforations 37 through which the rivet 38 1s passed which holds the slider together on a po nted filler block 38. Mounted to slide in the tubular yoke is a pull 39 having laterally extending branches .40 which engage with the inside of the tube. The ring 41 to which the pull 19 is attached slides in the slot 42 so that the pull 39 will always be operated from one end or else from the middle according to the direction of movement, and thus prevent wedging. In Fig. 13, the pull 44 consists of a flat plate having pro ecting pins 45, which act'm a; similar manner to prevent ofthe pull.
In Fig. 14 is shown a detail of the fastener assembly similar to that shown in Patent No. 1,219,881. 46 are sto members fastened to one or both of the stringers, whichact to sto movement by coming together 1n the sli er, and these stop members have aws constructed like the interlocking member jaws 20 or 24 above described, thereby securing a positive stop of the slider w thout wedging it apart or otherwise distorting 1t. An inexperienced or careless operator mlght otherwise seriously damage the fastenenby distorting the slider at the end of its closing movement, es ecially if in closing the fastener, the sli er has to exert strong tension on the members to be fastened.
In Figs. 15 and 16, the yoke 46 is single, having shorter legs which do not interlock with the lower end of the slider, but which bear on the slider wings sufficiently far to prevent the wings s reading. The lyl oke 46 also has a slot 13 w rich interlocks t e yoke and the slider by means of key 17, as before described. The yoke 46 receives a ring 48 to which any desired form of locking pull can be attached. This form has the channels so formed and at such angle as to open when the stringers are pulled apart, as in the patcut above referred to.
The present invention is being successfully used on automobile and other vehicle curtains, corsets, aviation clothing, and shoes, and is to be applied to numerous other uses where heavy strains are encountered in lookin and in remaining locked.
