Be .it known that I, Idlumnan RronR'r, a .citizenioff,Switzerland, ,and a resident of ,Waterbury, ,in 'the county of New Ha 5 State of Connecticuflha ve invented cer tai nnew fand useful Improvementsin Snap- F asteners which improvements arefully set I forth in the 'following specification.

. This invention relates to improvements in two-part devices of that class quite extensively availed of for garment fastening purposes, such devices being commonly known as snap-fasteners. I h j V The object ofthisinvention is to provide a sn'ap fastenerjof the character above, indicated,lwhich shall be simple and inexpensive as regards'i'ts construction; durable, efficient and reliablein practical service, and which shall pos' sessf certain 'well-defined' advantages over prior analogous constructions. Y V p The invention consists the combinations, detailsand' parts whereby, together with,thehoveldisposition and relativear irangement of said parts, the attainment of the foregoingobjecti is rendered practicable, all of which' will be hereinafter more specifically referred tof'an'd set forth injthe claims hereto appended; j j ".i j Theinventionis clearly illustrated in the accompanying drawing,wherein Figure 1 is a plan NElGW of af'snap-fa'stener 'embody'ing my said improvements, the main members thereof appearing in'the p0- 's itions "they respectively assume when brought into locking engagement, each with th'e-other.-

I Fig. 2 is a view similar to Fig. 1,,the studaffording memberv of the device appearing'as having been rocked upwardly out of its frictional engagement with the opposite, elasticmemberthereof, but not wholly detached'therefrom; a a

' Fig. 3 is an edge "elevation 'of'the device, the stud-affording member thereof appearing as having been rocked up wardly approximately as defined in-the description of *Fig. .lrlS a central, longitudinal "section of 'thedevice, as along the'dottedlinew m of Fig. 5 is a view showing in plan the elastic main member of the'device attached, as 'by'stitching,to a fragment of a wrist-band or-similar fabric.

55- *Fig. '6 isa View similar to Fig. 5',"showing V v k the stud-affording member ofthe device at wristband! or like fabric.

,Having;reference to v the accompanying drawing, whereln slnnlar reference-characters denote like partsthroughout the respective views, I, in carrying outlmy present invention, ,make use of a stud-affording main member, which maybe formed from any suitable material, preference being. given to .metal in thin sheet-form, and which comprises a duly elongated body 2, provided at tached, as by stitching, to' a fragment offs. :V

one end with a stud 2,'a n d at its opposite tion of said tang being turned away from said stud anddisposed tolie in parallelism, approximately, with the plane of saidbody. The stud-affording member a'forenamedfis provided with eyes, 3, 3, for facilitating the mounting thereof, asby stitching, on, say,a

wrist-band, as 3", i, n

Both the stud 2 the tang 2 may be advantageously formed integral with the body 2, and each given its required specific form, as clearly indicated in the drawing. 7 'I further make use of an additional main member, duly elongated andv itself elastic, the same'being' formed from anysuitable material, as Wire of an appropriate'gage and possessing measurable resiliency, said main member; being socketless, affording a primal stress-bar 4, at one end thereof, and having formed integral therewith, at its opposite end, an elastic studgrasping element. 7

' More specifically 1n this connection, said v additionalmembercomprises opposite sidebars, 4 ,f-it integrally connected" atithe neighboring ends thereof by ("the primal 'stressbar 4, either or both of said side-bars ree'of elasticity, and the member asafwho e'approximating in general form the character U." I

possessii'ig a, measurable de While-I have shown vthe last-named main member of my improved snap-fastener as being provided with eyes 5, 5, for facilitat ing"the"mounting thereof, as by stitching, on, say, :a wrist-band, 'asf5".,"-it is obvious that the mounting of themenciber now under consideration may'jb'eotherwise accomplished. H

6for 6, of either of the side-bars aforenamed, may constitute and serve" as, the stud-grasping" element hereinbefore 'mentioned,"jthi'sbeing obviously so 'where the Ina general sense the free end-portion, as if eyes 5, 5, are omitted, or given formation in a manner other than as herein defined, the end-portions of said side-bars, under such conditions, being so relatively arranged, nor mally, as to duly contract the space therebetween. v I p In this instance, however, said stud-grasping element performs its function, as will appear more fully hereinafter, nd reetly through the medium of 'the r'nateri'al availed of in giving formation to the eye, as 5 or 5, adjacent thereto and formed thereon, the end-portions of the side-bars aforenamed being, under such conditions, so relatively arranged, normally, as to duly contract the space intervening between the respective eyes 5', 5, as clearly shown in the drawing. As to the operation of my improved fastenen the main members thereof having been duly mounted on the opposite meeting margins, respectively, ofra garment, wristband, or the like, as in common' practice, the ne'er brings such meeting margins into such registry as to permit, primarily, the engagement, after the general manner of a heck, of the tang 2 with theprimal stress-bar 4, the stu'd-affording'member aforenamfed being nowpo'sitioned relatively to the additional or elastic member aforenamed, as though having been rocked out of registrytherewith, as on the primal stress-bar aforenamed and through the medium of the tangQ, (see Fig. 2) whereupon the deer rocks the studaffording member of vthe device over and upon the elastic or additional member thereof, and suihciently .so to cause frictional fengagement of the stud 2 by the elastic studgrasping element aforenamed,the main parts of the device being then securely locked together. I I e 7 During the operation aforenamed 'ofrocking the stud-aifording member of the device over and upon itscoeperatingmain member, a substantial. leverage isexerted, through the medium of thetang 2 and the stress-bar a, whereby themeeting margins tithe garment, are drawn more fully into registry, each with the other, this feature of my improved 'fast ener being highly advantageous.

Again, when themain membersof my improved fastener, shall have been locked together as hereinbefore. explained, all, stress, such as may. ordinarily be'brought to bearion the device as a whole, in practice, is mainly resisted, not by the frictional,holdingffdrce exerted onthestud2, butv by thetangil in conjunction with the stress-bar 4:, this constituting an additional important feature .of my improved fastener, and one rendered all the more feasible by thefactthat-the frictional holding force exerted on thefstud 2, while being sufficient to prevent any rocking action on the part of the Stlll-1fi0flll1glll6lfilb6f aforenamed relativelyto its coiiperating main member, still permits a measurable to and fro movement on the part of said studaffording member in parallelism with its cooperating main member.

. 'Itwill be apparent that when the respective main members aforenamed shall have been locked together, as hereinbefore, explained, the device as a whole will present a generally flat form, of minimum height or elevation. I

It will be seeii, that my improved snapfasteiier is well a'daptedfor the purpose for which it is intended, and further that the same may be modified to a considerable extent, particularly as regards the speeific character of the elastic stud-grasping element made use of, and various inino'rfdetails of the general construction, without departing fioin the scope of the claims hereto appended.
