OF BOSTOJ, MSSACHUSETTS,
Application filed JuneI le, 1924i.
This invention relates to shoes, and is particularly intended for use by molders in founderies and elsevi'hcr-e where the worlnncn are exposed to the danger of spilling;l molten metal into their shoes, thereby rendering,` highly important .not `only that the maximum of protection should be afforded against the entrance of the metal to the interior oi the shoe, but also to malte provision for instantaneous 'removal of the shoe to minimize the injury from such accident.
The prefent invention is intended to moet these requirements and consists essentially ina shoe whore top or upper portion is vented to form flaps, one overlappingthe other, the [laps being provided with interlocking fasd-evices on the snap fastener principle, arranged so as to permit the quick detachment or strippingl away of the outer flap from the inner one by a downward pull, while resisting` strains in a lateral or in an upward direction. Another .feature of the invention consists in rivet-ing or fastening the male members of the stud of the snap fasteners to a separate attaching st ip which is then sewed on the inner flap of the slicetop so that the fastener does not penetrate the inner layer of the leather, and in this way I avoid .producing objectionable and painful pressure upon the foot by the metallic fastener.
These and other features of the invention will be pointed out in the following specification and will be defined in the claims hereto annexed.
In the accon'ipanying drawings l have illustrated a preferred form of construction and arrangement embodying the principles of this invention, in which:
Figure l shows, in elevation, the shoe embodying my improvement exposing the inside face of the shoe to view.
Figure 2 is a cross section through the inner flap of the shoe-top, showing the fastening stud secured in place by the attachingstrip,
.Figure 3 is a side elevation vof the outer flap which carries the spring-containing socket elements of the fastening device.
According to the illustration in the drawings, the shoe-bottom 1, and the vamp 2 are of any usual or suitable construction. TheV shoe-top or ankle-surrounding ortion of the shoe-upper is made with a su' cient circumferential measurement or girth to provide, along the inside portion in front of the Serial No. 719,345.
ankle, an opening' or vent extending downwardly from the top with one edge, preferably the front edge, considerably overlapping' the other edge of the top. 'lhis forms overlanaping llaps at the vent or fly openingl on the side of the shoe to which the co-actingr elements ot the fastening devices, respectively, are secured,
The male fastening elementcompriscs an ane'ular'ly groovcd stud 5 which is preferably passed through and riveted, or otherwisesecured, to an attaching strip 4, which is itself thereafter secured to the inner flap of the vent in any suitable manner, as by say a row of stitches lla.
The socket member 6, comprises a shallow centrally perforated casing` within which is held the wire spring da, formed in the shape of a loop extending' around the interior of the shallow casing` with its free ends 6b eX- te-nding downward through the middle portion of the casing` and under such spring` tension as to norn'ially press toward each other. Near the free ends 6b, the arms of the wire are formed to produce an elongated open-v ing 6, starting from near the upper end of the casing and extendingl beyond the studreceiving openingformed at its center, as
Vshown in the lower fastener of Figure l.
This brings the stud-opening` opposite the lower .end of thisv elongated space so that, when 'the pointed end of the stud v'5, is forced between the spring aws or arms, they yield suiciently to allow the head of the stud to `pass through and then contract into the annular groove ofthe stud. As shown in Fig'- ure 1 the stud, when held between the" pinchino; jaws, is, therefore, located in the lower portion of the elongated space formed by the separated portion of the jaws so that the head of the stud overhangs the inwardly turning; free ends of the wire. The consequence is that any pull from below 0r from either side of the stud is strongly resisted by the overhanging head. On 'the other hand, the open space between the wire jaws on the opposite or upper side fof 'the stud allows the upper end of the outer fasteningv elementto swing outwardly since this side of the head does not overhang the wire and, therefore, the head acts as a wedge to force apart or open the jaws sufficiently to allow disengagement of the wire from the annular groove.
As shown in the drawings the open or releasable side, or if we consider the direction of the spring jaws as constituting the longitudinal axis of the stud-receiving; elennent-i'.' the releasable ends of the stud-reeeivingr and locking elements all face upward in substantially the saine direction, that is, substantially parallel with the direction of the vent itself so that a single outward pull at the top of the outeil flap instantly7 releases or strips the outer flap from the inner one.
lt will thereforeY be seen that the direction of setting' of the fastening device is iniportant, the essential requirement being` that the fastening' element-s be set to resist all strains that inay be exerted by the foot inside the shoe and yet allen' the vent to be opened practically instantly by an outward and downward pull on the tab end 3C of the outer flap.
lt. will be understood that I inale no claiin in this application to the fastening stud per se, but the provision of the shoe flaps of the vent vith a quick detachable fastener that is opened 'or disconnect-ed only by an outward pull from the top is an important feature of the present invention because it insures a gainst the accidental openinjrl of the vent under any strains or stresses that the shoe is subjected to by the foot inside and yet allows the instantaneous opening 'of the vent froni the top by a siinple outvfard pull.
Vilhat l claim is:
l. ln a inoldcrs shoe the combination with a shoe upper top formed with a vent extending downwardly Whose side edges forni overlapping flaps, the inner flap beingprovided with a plurality of properly spaced outwardly projecting studs, and the outer flap being,` provided with a correspondingly arranged series of coacting stud-receiving` fasteners formed to interlock with the studs so as to prevent disengagement therefrom under the lateral and upward stresses lof Vthe tout` while readily released by a single outward pull exerted at the top of said outer flapy substantially as described.
ln a niolders shoe the con'ibination ol a shoe upper lop formed with a vent extending downward from its top edge7 and diinensioned to forni overlapping flaps to close said vent, the inner and the outer flaps bciugrv provided with cooperating interlock ino' fastener elel'nenls each arranged to reu' itter with its coacting element when the vent is closed, said elements being releasable troni their locked engagement only by a single outward pull exerted on the outer flap 'troni above the location of the fasteners, suba-ituntially as described.
23. In niolders shoe the combination with a shoe upper top having a vent opening er;- tendinp; downwardh from tire tcp on one side of the inedial line with overlappinfbT flaps, a series of snap fastener .elements ccf operatively arranged on the respective flaps and con'iprising', respectively, a row of studs and a rouv of registering' stud-receiving' and locking' n'ieinbers adapted to open in one direction only for release frein the studs, said studreceiving inenibers having' their releasable ends facing;r upward in substantially the saine direction so that a single i, l outwardly at the top serves to instantly strip the outer rlap frein its fasteners, While said fasteners rei-'ist release frein lateral p ti nsversely of the vent, substantiallj.' as cc- 'ibed. l. A inolderls shoe embracing' in combination a shoe upper top pro' led with a rent extending# dmvnivardly from its uilnl'ier erige and dinien 'oned to forni overlappii f; i normally ciosin j the vent, coacting; scri interlocking fastener elements secured to the respective flaps, the inner fastener eleinents penetratin` and being secured to a .separate strip of material that is secured to the outside 'tace of .said by stitching to avoid piercingv the flap itself, the outer flap having' its upper end extending sufi'ieiently beyond the topniost fastener to forni a tab adapted. to be grasped by the hand, said fastener elements being` releafeble frein interlocled engagement by a single outward pull yon said tab While preventing` the pressure of the enclosed foot from effecting such disengagement.
5. A inold rs slice embracing in coinbiuation a downwardly vented shoe upper top diinensioncd to forni overlapping' flaps to clore said. veul; a serios of outwardly." p jrcliun fastener studs secured to the inner iniper'l'orate tlap by nic-ans of an attaching strip secured on the outside of said flap, a rcn'istei'iug' of .stiu'l-receiving` Fastener clcnicuts secured to the outer flap and arranged to be released from interloclrinpr en- Ia'axcjenicnt with said studs 'only by an outward pull exerted on the upper cud ol' the outer tlap above the llislrncrs1 substantially :is described.
