FASTENER.

Application filed November 21, 1923. Serial No. 676,016.

To @ZZ whom t may concern.'

Be it known that I, CHARLES P. S'roon'ror, a citizen of the United States, a resident of Melrose, in the county of Middlesex and State ofA Massachusetts, have invented an Improvement in Fasteners, of which the following is a specification.

This invention relates to that class of fasteners which are primarily designed and intended for use to fasten overshoes, raincoats and the like, in which two fastener members are connected. at opposite ends to the garment portion to be fastened and are adapted to be adjustably connected.

The invention has for its objects to provide a form fastener of this type in which all projecting parts are eliminated which are likely to catch on the clothing, also to provide a fastener with which the members are unlikely to become accidentally disengaged and which may be readily manufactured, to a large extent, by a stamping process.

I accomplish these objects in the manner hereinafter described and as illustrated in the accompanying` drawing in which:

Fig. l is a perspective view of a pair of fastener members embodying my invention, on an enlarged scale.

Fig. 2 is a plan view'of the under side thereof.

Fig. 3 is a longitudinal section at line 3-3 of Fig. 2.

Fig. 4L is a sectional view at line L -4 of Fig. 3.

Figs. 5 and 6 are sectional views at lines 5--5 and 6 6, respectively, of 'Fig 2.

According to my invention, I provide a pairv of oblong shaped fastener members a and l), which are adapted to be attached at opposite ends, respectively, to the opposite portions of an overshoe or garment to be fastened together, one on the other, the outer member a having its longitudinal edge portions bent downward and inward to form guideways c for the edge portion of the inner member Z2. so that the latter may slide freely therein. The members may be curved as shown, or straight, according to the purpose for which they are to be used. The inner member b is slotted from its end opposite the end which is attached along its middle portion, forming a slot d, and a series of corresponding, segmental shaped recesses c are formed in the opposite side portions of said slot, forming intermediate projections f, which are directly opposite each other, the distance between the ends of the opposite projections corresponding to the width of the slot. The opposite recesses may be considered as circular holes of uniform diameter and intersected diametrically by the longitudinal slot (l.

A spring tongue g is struck out from the metal of the member a, at the lmiddle thereof, and in a position in which it extends longi tudinally of'the member from its attached end, and is spring set in a position in which it extends divergently from the outer surface of the member, so' that the tip or end portion gl of the tongue is normally held at a substantial distance from said outer surface. The end portion g is slightly enlarged and has rounded edges tapering to the eXtreme end and a stud 7L is iixed at one end in the middle of said end portion y said stud having a flange portion i, at its opposite end, the diameter of which is somewhat greater than the diametrical distance from the bottom of one recess c to the bottom of the opposite recess, a head-portion y', the diameter of which is approximately the same as the circular holesforming said recesses, so that it may be received thereby, and an intermediate shank portion 72, the diameter of which is slightly less than the distance between the opposite projections 7c. The end portion of the stud which is iiXed in the tongue, is preferably secured by riveting, as indicated in Fig. 3. The tapering end portion of the tip portion g of the tongue is bent downward at approximately right angles, to form a guard lug m, which depends therefrom to a point slightly below the level of the outer surface of the member a, so that in the normal position of the tongue, shown in Fig. 3, there will be no projecting` end which is likely to catch on the clothing. A pair of longitudinal ribs nare struck up in the inner member b to give it increased stiffness.

When the fastener members are to be connected, the tongue g is depressed to its fullest extent, causing the shank portion of the stud to be moved into a position opposite the guideways c, so that when the member is inserted in the guideways, the slot al will receive this portion of the stud, and as the distance between the ends of the projections f, or the narrowest portions of the slot is slightly more than the diameter of the shank portion-lc, the member b may be slid beneath the member ca to any point.

v sliding movement beneath the member a.

To disengage the members it is merely necessary topress the tongue inward until the head portion is disengaged from the recesses inthe slot of the inner member and then the members may be slid relatively as will be obvious.

In the locked position the parts will be securely held and the' probability Athat the ,tongue will be accidently pressed inwardly to a sufficient extent to cause them to become unlocked is remote. n'

' The two fastener members are of such a construction that theyI may be readily stamped out of sheet metal and the stud may ybe readily made by automatic machines. 1 f

l. A fastener comprising an outer and an inner member 'adaptedA for attachment at opposite ends, said inner member being arranged for slidable connection with the outer member at its innerv side and having a longitudinal slot therein extending from its` unattached end, said slot having a series of oppositely disposed recesses'fopening thereto at each side, a resilientftongue connected to said outer 'member at its attached end' and normally extending towards its opposite end in divergent relation with the outer side thereof, a locking pirojection rigidl with said tongue and extend-- ing from the end thereof through the outer member in position to enter the slot of saidv inner member, said projection having an intermediate shank portion adapted to be received by said slot and a head portion at its inner'end adapted to be engaged in the recesses thereof when the tongue is in normal position to be disengaged therefrom when it is pressed inward.

2. A fastener comprising oblong, outer and inner members, arranged for attachment at their opposite ends, the outer member having longitudinal guideways in which the inner member is arranged to slide at the inner side' thereof, and said inner member having a longitudinal slot extending from its free end, said slot having a series of oppositely disposed recesses opening thereto, a resilient tongue connection to the outer member adjacent its atta-ched'end and extending at the outer side thereof towards its opposite end in divergent relation thereto, said tongue having a locking stud fixed therein at its end and movable thereby through said members, said stud having an intermediate shank portion adapted to bereceived bysaid slot, a head 'i portion at its inner end adapted to be receive'd by said opposite recesses to lock the members against relative sliding movement and a flange at the inner end ofthe head to engage the inner side of the inner member, said stud being` movable by 'said tonguebetweenl positions in which either its inters mediate portion or its head portion mayV be longitudinally of said outer member and i spring set in divergent relation relative thereto, and va stud fixed in the end of said y tongue and extending through said outer member into the slot of the inner member, said stud having a circular head portion at its inner end adapted to be received bysaid circular holes and an intermediate shank portion adapted to be received by saidslot, the length of said portions `corresponding to the thickness of said inner member whereby either portiony may be held in said slot.

4l. A fastener comprising an outer and an inner member adapted for attachment `at opposite ends, said inner member beingarranged for slidable connection with the outer member at its inner side and having a longitudinal slot therein extending from its unattached end, said slot having a series of recesses opening thereto at vone side, a resilient tongue connected to said outer member at its attached end and normally extending towards its opposite end in divergent relation with the outer side thereof, a locking projection rigid with said tongue and extending` from the end thereof through the outer member.in-position to enter the slot of said inner member, saidlprojection having an intermediate shank portion adapted toA be received by said slot and a head portion at its inner end 'adapted to be engaged in the recesses thereof when -the tongue is ink Y normal position to lbe disengaged therefrom when it is pressed inward 5. A fastener comprising an outer and an inner member adapted for attachment at opposite ends, said inner memberbeing arranged for vslidable connection Awith the outer member at its inner side and having a longitudinal slot therein extending from its unattaehed end, said slot having a series of recesses opening thereto at one side, a resilient tongue connected to said outer member at its attached end and normally extending towards its opposite end in divergent relation with the outer side thereof, a locking projection rigid with said tongue and eX- tending from the end thereof through the outer member in position to enter the slot of said inner member, said projection having an intermediate shank portion adapted to be received by said slot and a transversely projecting head portion at its inner end having a locking portion adapted to enter any one of said recesses when the tongue is in normal position, and a stop portion arranged to engage the inner side of the inner member to limit the outward swinging movement of said tongue When said locking portion is engaged in one of said recesses.

Iny testimony whereof, I have signed my name to this specification.

CHARLES P. STOCKTON.
