Reiscued Dec. 2, 1930 UNITED S A-res PATENT OFFICE GIDEDH SUNDBAOK, OF HEADVILLE, PENNSYLVANIA, ASBIGNOB '10 HOOKLESS FAB- TEN'ER COMPANY, A CORPORATION OF PENNSYLVANIA FA STENEB Original application flied April 2, 1917, Serial No. 159,189. Divided and application filed August 15, 1821, Serial Io. 498,621- l'etent 110. 1,608,188, dated September 8,1182. Application for reissue died December 8, 1829. Serial No. 411,357.

This invention relates to fasteners of the type wherein closures for the edges of a garment, curtain, bag, tent or the like are to be separately connected by a fastener which em- 5 bodies a sliding crating device which separates the edges when moved in one direction and closes them when moved in the opposite direction. Hitherto in the use of such fasteners, the degree of separation permitted has been limited by the fact that the edges had to remain joined at at least one point. By a novel arrangement of parts, involving the use of a flexible extension member, I have made it possible to secure as wide an opening as may be desired. By reason of this advantage, In invention is particularly applicable to sue articles as corsets, spats, curtains, etc., where wide separation, without actual disconnection is required. This application is a division of my previous application for fastener, Serial No. 159,139, filed April 2, 1917, Patent No. 1,403,988, January 17, 1922.

With these and other objects in view, I have devised the apparatus embodying my invention, as described in the following specification and illustrated in the accompanying drawing, of which- Fig. 1 is a plan view of the device as ordinarily applied,

1 represents a bod having edges 2 which are to be closed. e fastener embodies stringers 3, 3 composed of tapes having corded edges 4, 4 to which the interlocking members 5 are clamped in staggered relation. A

sliding hollow Y-sha ed cam 6 fits over members 5 and travels a ong edges 2 to engage or disengage the interlocking members 5 on the respective edges 2. Cam 6 has slotted sides through which the tapes extend laterally but which retain members 5 a ainst forces tending to separate ed es 2. '%he tapes of stringers 3 are stitche res ectively to the separate portions of body 1 eyond edges 2. One or both of the stringers 3 are provided at the closing end with stop members 7 passing within the slider 6, and engaging the latter to prevent further movement.

Beyond the end of body 1 stringers 3, 3

are extended to constitute extensions 8, and

these extensions are connected at their outer ends by link members 9 joining the respective stringers. The stringers in effect thus constitute a single body provided with a slit. Extensions 8 are preferably provided with m interlocking members 5, and are of such a: lengththat when slider 6 is stopped by link members 9, the body 1 can be separated to such an extent that the extensions 8, owing to their flexibility, will straighten out end to end. In the fasteners as heretofore used, without extensions, the end members 9 would directly connect the lower end of body edges 2, and slider 6 would consequently not go the entire len th, thus preventing complete separation o edges 2. By reason of extensions 8 receiving slider 6, as much opening may be secured as desired, depending on the length of extensions 8. As the free edges of the ex tension 8 straighten out end to end, the max- 5 imum degree of separation of the lower edges of body 1 will be about twice the distance of aha top of slider 6 from the lower edges of Iii Fig. 3, the extension principle is applied 90 to a boned edge corset, and permits the corset to be put on or taken off without requirin complete opening. 10 is the usual lacing, an 11 is the fastener of this invention. The body of the corset ends at 12, and 13 are the extension members. When the slider is moved down to the lower ortion of the extensions 13, these can stretc out end to end to such an extent as to permit the corset to be stepped into or out of without complete separation, 10o

and when the slider is pulled up the corset will be quickly and firmly fastened.

In Fig. 4 is shown an application of the extension to a spat, in which 14 represents the bod of the spat provided with the fastener as s own, the instep strap 15 being split and carrying the stringer extensions. When the slider 16 is moved down to the extreme bottom, strap 15 stretches out end to end and makes such a wide opening that the spat can easily be slipped on and off the foot without disconnecting the strap from the body, as 1s the usual custom. In Fig. 5 the strap 15a is not split as in Fig. 4, and only one stringer is connected thereto, the strap also being sewed only to the body 14 on the side to which the stringer is attached. Thus the slider can go down to the lower end of the stringers as in I Fig. 4, and the stringers will stretch out end to end so as to provide the wide opening. Inasmuch as the body of the spat 14 overlaps the free side of the strap, it makes no difference that the strap is not attached to the body on both sides.

InFig. 7 the extension principle is applied to a curtain 17 carried by a body or support 18, such as a tent, automobile top, etc., and the stringer extension 19 is sufficiently long to permit curtain 17 to be swung around relatively to the support when separated. The other stringer extension appears as attached to body 18 for its entire length but it may be partly free if desired. This arrangement is a decided advantage in enabling the curtain to be rolled up.

Another important feature ofmy invention is the locking means which is best illustrated in Figs. 2, 8 and 9. Asheet metal plate 22 is attached to the reinforcing loo 23 at the rear end of the slider by means oi extensions 29, which are bent to lie within the loop 23 and serve as a pivot about which the plate 22 may be moved. The slider can be posi tively actuated in either direction by means of the plate 22 which functions as an actuator when lifted upwardly away from the slider and as a slider lock when pushed down so as to lie closely a ainst the slider and overlap the closing en Spring wings 24 project from the plate in a position offset from the longitudinal center line of the slider and offset laterally from the extensions 29. Such wings or projections act to block the passage throu h the slider and prevent relative movement between the slider and fastener stringers. Each ofthese wings in the embodiment illustrated, obstructs one of the diverging channels of the slider adjacent its rear end, that is, the wide end of the slider where the separated stringers project therefrom, when the plate 22 is swung downwardly into locking position. They will thus engage the stop member 7 and revent their movement outwardly from the slider and thus lock the fasteners against opening.

It will also be apparent that when the slider is thus looked as illustrated in Fig. 2, that the locking wings 24 will project toward and into proximity to the corded edges 4-4 of the stringers, thus providing a more secure locking effect. In Fig. 2 it will be seen that the locking wings are positioned directly opposite the slider wedging portion 30. It will be of said respective edges for connecting the same, means movable progressively along said edges to control said connecting means, and an extension beyond said body constituting in effect a continuation of said edges for receiving said movable means when said edges are disconnected, whereby to increase the separation.

2. The combination with a separable body portion, of stringers on the adjacent edges thereof extending substantially beyond the body portion, connecting members on the stringers, means sliding on the stringers to controi the connection, and means beyond the body portion for limitin opening movement of said sliding means after it has passed substantially beyond said body portion.
