FASTENER Filed Oct. 29, 1931 Inveni'm":
Patented Dec. 4, 1934 Application October 7 29,
This invention pertains to fasteners of the kind usefulin adjustably constricting a gap or open- 7 ing, for examplein a garment, bag, belt, band, bight or other article, device or element and relates more particularly to afastener comprising relatively movable'parts which are always engaged, which may be relatively adjusted by as small amounts as desired, and which remain in adjusted position until readjusted. While of 10'- general utility for the purposes just indicated, the invention is herein specifically described and its advantages made manifest with relation to it's embodiment in an article of footwearsuch, for example, as a shoe. 7
In common with many other articles of wearing apparel, shoes are usually p'rovidedwith an opening having appropriate fastener means whereby the opening may be more or less constricted. While certain types of fasteners, for example,
of metal or other hard and rigid material, sometimes having corners or edges which injure thewearer or tear his other'garments, and are adapted to close the opening only to a predetermined and fixed amount, other types of fastener, for
example, laces may be of soft and flexible ma-- provide a constrictive closure of adjustable type which, like the usuallacingmonsists of soft and flexible elements which can not injure the wearer' or his other garments; which may be of any desired color;--and whichin general appearance may resemble an accurately tied bow knotlbut; which may be tightened and loosed by a simple pull in'the proper direction, and whose parts re main in any position of adjustment regardless of the stressto which they may be subjected in use,
and which may be used for constricting any form of bight;ba'nd or opening; all as hereinafter more fullyset forth. I I
In the accompanying drawing I haveillustrated by way of example one embodiment showing the invention as applied to a shoe of a kindcommonly worn by childrenor used for sportwear,
it being'understood that this embodiment has beenchosen merely as illustrative of the utility of the device and that the device its' broader buttons, snaps, hooks or the like must usually be 1931, SerialNo; 571,769 (o1. es-50) aspects isuseful for constricting openings inother articles of wearing apparel as well as in devices in general having openings which are to be ad-v justably restricted.

- Referring to-the drawing, the numerals 1 and 2 (Figs. 1 and2) respectively indicate lengths of flexible materiaLeither independent a'sqspecifically'shown in Fig. 1 or forming opposite end portions of a bight or, loop as specifically shown in- Figs. 3, 4 and 5. As shown in Fig. 1 these lengths of material 1 and 2 are secured, as for example by stitching, to parts 3 and 4 whichmay be considered as representative of the edge portions, of pieces of material defining the opposite edges of a gap or opening to be closed or constricted. The parts 3 and 4 may be'independentelements or mayform the free ends of abight; or band or the edges of a garment section.
The fastener herein'disclosed may be considered as comprising two cooperating sections of which the parts 1 and 2 constitute the anchoringor attaching element, and these sections may be regarded if desired as the ends of a bight to be constricted. Each section may conveniently'be made from a length of .tubular knitted textile fabric: Thus one section com-' prises the attaching portion 1,;which may be fiattened'before securing it to part'3'and thesubstantially cylindrical portion 5, hereinafter referred teas a gripper or tubular sleeve. 'Beyond theend of sleeve5 the material is againfiattened' and then doubled at 7 to provide the loop-portion 8 whoselength isfixedbysuitable fastening means, for example stitches 10. Beyond the stitches 10 this length of material is provided with the extension 11 which, afterpassing' longi= tudinally through thebore of the gripper or tubular sleeve 12 of the opposite section, preferably is furnished at its free end 9-with an" enlargement or stop 13", for example a knot'yto prevent its retraction from the gripper sleeve 12, and betransversely through an opening 20 in the. part 11 at a point near but inwardly of the stitches 10.
Beyond this point the extension 19 extends longitudinally through the bore of the gripper sleeve 5 of the opposite section and its free end 17 is furnished with an enlargement such as a knot 21, and with the tassel portion22 if desired.
In making this device it is'preferred, as above noted, to make use of a length of tubular braided material, for example textile material, although material not commonly referred to as textile'material, for example paper, rubber or wire, may be used,and in constructing 'thedevice I prefer first to provide the loop members 8 and 16 of the opposite sections, then to passthe free end of the extension 11, for example, inwardly through an opening in the wall of the part 12, thence longitudinally of the bore of said part 12, and thence out through another opening in the side wall of the part 12, after which the knot l3'is formed. In the same way the free end of part 19 is first passed transversely through an opening at the vpoint 20, then inwardly through an opening in the side wall of the part 5, then longitudinally of the bore of the latter part, and thence out through another opening in the side wall after which the knot 21 is formed.
It is a property of a tubular braided structure to contract very substantially in diameter when subjected to longitudinal stress and, on the other hand, to increase substantially in diameter when contracted in a lengthwise direction. While tubular braided fabric exhibits this property to a very marked degree, certain other structures consisting, like tubular braid, of two series of helically extending overlapping strands of opposite pitch exhibit similar characteristics, while other tubular textile materials show the same effect to a lesser degree, for example bias knit fabrics. Thus when in the following description and claims I refer to a gripper sleeve, gripper device, or tubular gripper, I intend to indicate a sleeve-like member, whether of braided or other construction, and/or of whatsoever material which exhibits the characteristics above referred to, namely, capability of elongating substantially and contracting greatly in diameter when subjected to small longitudinal stress so as to grip and securely hold any part fitted within it and which, when contracted longitudinally, shows a marked increase in diameter such as to release its grip uponan enclosed part. v
The fastener device above described may be considered as comprising a pair of tightening pulls 9 and 17, respectively, having their ends exposed to form actuating elements for tightening the fastener, thereby constricting the opening to which it is applied, and as further comprising a pair of loosening pullsconsisting of the loops 8 and16, which, when moved in opposite directions, loosen the fastener, thereby 'increasing the size of the opening. As shown in Fig. 1, the fastener is in its most extended condition. and it will be noted that the gripper portions 5 and 12 are contracted longitudinally and are of substantial diameter. In this condition these gripper portions exert little gripping action upon the members 19 and 11 respectively which extend longitudinally through them, but if force is applied, for example to the parts 3 and 4, tending to pull the members 5 and 12 away from each other, such action immediately elongates the parts 5 and 12, (due in part to the frictional drag exerted by the parts 19 and 11) causing the grippers to contact and grip the parts 19 and 11 respectively so firmly that relative movement of the parts is effectively prevented. When using soft textile material, this gripping effect is in many cases sufficient to hold the parts against a stress suflicient to break the 'fabric. On the other hand, when it is desired to loosen the fastener so that the parts 3 and 4 may be moved away from each other, it is merely sufficient to move the parts 8 and 16 in opposite directions, whereupon the force exerted on the inner ends ofthe respective gripper sleeves 5 and 12 causes the latter to decrease in length and increase in diameter so that the gripper sleeves may slide easily along the parts 19 and; 11 respectively, thus allowing the parts 3 and 4 to be separated. i
In Fig. 2 the fastener is shown in its most contracted position with the gripper members 5" and 12 elongated, as by stress applied in opposite directions to the parts 1 and 2.
In Figs. 3, 4 and 5 the improved fastener is shown as applied to a shoe comprising the sole 23, the forepart 24, and the rear part 25. The forepart is furnished with a binding 26 and the forward edge of the rear part 25 is furnished with a binding 27 at one side and binding 28 at the other side, said latter bindings preferably terminating at their upper ends in loops 27 28*, respectively. A strap 29 extends upwardly from the forward part 24 and terminates in a loop 30.
The upper edge of the rear part 25 of the shoe is finished with a binding strip, preferably extending continuously around the rear part of the shoe in the form of a bight or loop comprising 12 of Fig. 1 and with the loosening loops or,
pulls 8 and 16%, respectively. The substantially parallel extensions 11 and 19 pass through the loop 30 of thestr ap 29 and then through the grippers 12 and 5 respectively, and. are furnished at their free ends 9 and 17 with the.
stops 13 and 21, respectively.
When this shoe is to be put onthe footthe pull members 8 and 16* are moved in opposite directions to .the positionshown in Fig. 5, thus providing a maximum opening for the receptionv of the foot. When the foot has been inserted in the shoe the pulls 9 and 17 are pulled in oppo site, directions, thus constricting the top of the shoe about the foot, and when sufficiently tightened the ends are merely released, whereupon the gripping members 5 and 12 actto lock the parts in position .until they are posi-- tively released by pull exerted on the members 8 and 16%. The shoe may thus .be..,secured on the foot by pulling the parts 9* and 1'7 and may be loosened for removal simply by pulling the parts 8 and 16*.
It may be noted that the fastener thus provided is devoid of any metallic parts such as might cause injury to the foot; it may be made of flexible and soft material adapted to take any desired color; it is automatic in its locking action but is readily released by a simple pull when desired; and it provides for any desired degree of adjustment of the opening without requiring the manipulation of special parts.
It is further to be noted that when the shoe is tightened about the foot, as shown in Fig. 4, the fastener has the appearance of a perfectly formed bowknot, thus giving the shoe an ornamental appearance, although the formation of such knot requires no skill upon the part of the user.
For certain purposes it is not necessary to provide a fastener having the symmetrical bow-knot appearance and thus, as shown in Fig. 6, the fastener may be constructed without passing one of the extensions through the other one as above described. As shown in Fig. 6, wherein the parts are designated by the same numerals as in Fig. 1, it will be noted that the part 19 does not pass through an opening in the part 11 before entering the sleeve 5, and while this fastener operates in the same way as that above described, its appearance is somewhat different from that of Fig. 1.
While I have hereinabove described certain materials as useful in the construction of the fastener and its utility for certain specific purposes, I Wish it to be understood that it is capable of manufacture from materials of various kinds and that it is of broad utility, and that all such uses and such materials as well as variations in structural details fall within the scope of the invention as defined in the appended claims.
