SNAP rAsrENER.

Application led December 10, 1923. Serial Nic. 679,690.

To aZZ whom "it may concern.; I

Beit kno-wn that I, JOHN A. MANDIs, a citiZen of vthe United States, residingrat Highland Park, in the county of Wayne 'and State of Michigan, have invented new and useful Improvements in Snap Fasteners,

of which the following is a specification.

This invention relates to fastening devices,

and in general contemplates simplifying the construction of a device lto be primarily used in the same capacity as the device illustrated in Patent #1,370,468, issued to me on March 1 1921. v

7,Vihile the invention comprehends the provision of a fastening device primarily intended for holding a neck tie secured to thev front of a shirt, and incidentally `main'tain' the tie in proper position with relation to the collar, the fastening device is susceptible of an unlimited number of uses, `all of which are contemplated by the claim.

The invention embodies a. two part fastener, one pant being in the nature of a headed pin, and the other part in the nature of a cap` designed to receive the shank of the pin, and including a slotted slide which in one position'engages the shank of Ithe pin to hold the respective parts of the device associated. Y

The nature and advantages of the .invention will lbe better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in Athe construction, combination and arrangement of parts claimed.

In the drawing forming part of-this application, like numerals of reference indicate similar parts in rthe several views, and wherein:

Figure 1l a view showing the respective parts of the fastener separated.

Figure 2 is a View showing the parts associ-ated.

.Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure` 4 is a detail view of the cap member. j

Figure 5 is a detail view of the resilient member.

Figure 6 is a detail view of the slide.

Figure 7 is a detail view of the guide therefor. f

Figure 8 is a. detail view of the topy or cover for said cap.l

The fastening device essentially embodies two parts vindicated atA respe'cftively'4 I in Figure 1,the part A beingin the form of a lheaded pin, the head of whichis indicated ait-10 and theshanlV at 11d"l The shank isv reduced as at 12 to cooperate with a. locking element to 'be hereinafter described wheiehyl i theparts and B are held associated.' The underside of the, head 41Y0Y is preferably roughened j as at 13 to effectively grip Vthe material through whichtlieshfanlrofwthfe is passed incident to its association withfthe i part B.

rlhe part vB includes a capV shaped 141, the bottoml part of which isy substantially of conical formation formed withV adepress sion 15to`receive the lower end of the shank when the parts A and B are joined together. The cap is formed to provideV an internal shoulder 16 upon which the dii'erent'meiirhers of this partl ofthe device reposes. y In other words. l Vmalte use of a memberI 17 which is' `slotted as at 18Qtodefine a resilient tongue 19, this` tongfuey having a eentral'op'eniig k2O,

and a tit'orj raisedf'portion 2l at a pintad# jacent its lfree extremity.l Arrangedupon this resilient 'member is a disk like mem-ber' 22 constituting a guide for the `slide "23.l This slide is arranged to move overV the resilient tongue 19 which Vis allowed to Aoperate within tlie'U-shaped ntien'iloer22.- j t The slide'` being provided with a restricted slot 24@ which terminates'in an opening 25. rllhe slide or llocking element is further provided with a transverse opening 26 adjacent one end thereof, which end of the slide is formed to pro-vide a linge-r engaging lip 27 arranged exteriorly of the cap 14. The opposed longitudinal edges of the slide is formed with spaced shoulders 28 and 29 respectively, and these shoulders are adapted to alternately contact lugs v30 projecting inwardly from the opposite sides of the U- slide as will be readily understood. The j disk 31 is fitted within the cap shaped member 111 and holds all of the parts in a super` imposed relation, this dislr 31 i having a.

lshank of the pin is to be passed, and the locking element or slide 23 pulled outwardly so las toposition the opening4 25 of this slide in axial alignment with the opening 2O oit' the resilient tongue 19 and with the opening 32 of the diskv 3l. The shank ll of the pin is then passed through all of these parts, and when the parts A and B' have been thus associated, the reduced portion l2 of the shank is arranged at one end of the slot 24 formed in the slide 23. Consequently, when the slide is pushed. inwardly' to it-s active position within the cap shaped member 14, the opposite sidesk of the slot :24 engage the reduced port-ion 1Q of the shank and holds the parts A and B immovably associated. When the slide reaches the limit of its inward movement, the transverse opening of the slide is arranged immediately above the tit or raised portion 21 of the resilient tongue and this tit or raised portion thus snaps into the transverse opening of the slide holding the latter in an active position. This construction of course, prevents casual separation of the parts, inasmuch. as the locking slide or element cannot be accidentally moved to an inactive position, but nevertheless the slide can be easily pulled outwardly when it is desired to separate the parts A. and B of the fastener. It

. might .here be stated that the fastener can be'used as a scarf or stick pin, or as a fastener for lodge emblems or the like, it is also particularly useful as a separable or detachable button which can be used on garments, especially overalls or the like, so that the buttons .can be removed when it is necessary to send the garments to the laundry. The simplicity ot the construction, plus the convenience with which the component parts can be assembled or disassembled are characteristic features of the invention, and it is 4to be further understood that it is not necessary to provide a button oit the invention will be readily apparent', I

desire to have it understood that I do not limit myself to what is herein shown and rl described, and-that such changes may be resorted to when desired as fall Within they scope of what is claimed.

Having thus described the invention, I claim: y

A two part fastening device, one part including a headed shank, the other part em,` bodying a cap shaped member, a disk closing one end of the member and having a cent-ral opening, an internal shoulder formed on said cap, a slide adapted to be moved inwardly and outwardly of said cap, a` U. shaped member supported by said shoulder and constituting a guide for .said slide, cooperating means carried by the slide and said guide 'for limiting the movements of the former, said slide having an opening` adjacent one end and adapted to coincide with the opening ot said disk to receive the shank of the first mentioned memberwhen the slide is moved outwardly, said slide also having a longitudinal slot to receive said shank when the slide is moved inwardly, and thus hold the respective parts of the device associated, and a member supported by said shoulder and including a resilient tongue operating within the U-shaped member, and cooperating means carried by said tongue and slide "for holding the latter iXed relatively to the cap shaped member when moved Within the latter.

In testimony whereof I afiix my signature.

JOHN A. MANDIS.
