IASTENING DEVICE. i

`Appiitatmn niedQnovember 11, `1927. serial No. 232,630.

This invention relates generally to fastening devices and, more particularly, yto a certain new and useful improvement in fastening devices of the type commonly known as buckles. d

My invention has for an object the provision of a buckle especially adapted for belts,

straps, and the like, which comprises few,

conveniently manipulated parts, and which dispenses ywith teethwor other such more or less material-ruining gripping means for holding the buckle to the material. Y

My invention has foranother Aobject the provision of a buckle which shall be simplep convenient, lightand compact, economical,

reliable, and elicient and satisfactory for use wherever found applicable.k

My invention has for still another object the provision of a buckle which, when once adjusted, will hold at lsaid adjusted position My invention has for a further objectthe provision of a buckle which shall have no pivoted parts, apt to come out of order after limited usage but instead will have slidable parts with Y large bearing `surfaces and adapted to grip or clamp the material there in, in either direction of attempted relative movement between the material and the device. Y l.

Many other objects and advantages of the construction hereinshown and described will be obvious to those skilled the art to which this kinvention appertains from the disclo-v sures herein given, andwith all such objectsV in view, my invention resides in the novel features of form,construction, arrangement, and combination of partsherein shown and described and pointed` outv in the claims. f

In the accompanying drawing,`

Figure l is a plan view of a fragment o f a garment equipped with a buckle embodying my invention; v

Figure 2 is a longitudinal sectional view taken approximately on the line 2 2,

-Figure 1;

Figure 3 is a cross-sectional View taken approximately on the line 3 3, Figure 2;

Figure 4 is a plan view of the buckle as seen from the rear or under side;

Figure v5 is a plan view of a clasp or fastening member adapted for (zo-operation with the buckle proper; and

Figure 6 is aV modified form of fastening-y member also adapted for co-operation with .the buckle shown .in Figure 4.

Referringnowmore in detail and by ref-v erence characters to the drawing, wherein I have illustrated preferred embodiments of my invention, A designates a garment of any suitable type, such as knickers` for s ort wear, the lower endl of each legof wllich has a flexible band or strip l therearound adapted for adjustment ,so as to tightly encircle the wearers knee, the free end ofthe stripkbeing indicated at 2. Ordinarily, so

far Ias I am aware, a buckle having a tongueV thereon adaptedvto selectively engage in one of a series of apertures through a tab is used for this purpose, or a clamping member vhaving gripping teeth thereon is substituted for the tongued buckle; but with such devices, Y

which have generally been unsatisfactory, the cloth of the garment is very apt to become ytorn or otherwise kdamaged under strain.

To overcome these `and otherk defects,

have provided a vbuckle made of substantially Abut twoparts, which areadapted to grip the material of one end-portionof the band or strip to prevent relative movement therebetween ineither direction after the desired adjustment has been made, the opposed end of the band or strip having a fastening or clasping member thereon adapted for cooperationy with the buckle in securing the ends of the strip together.

.The buckle Vproper is indicated atB and consists of a pair of flat plates 3A and 4, termed the front and r'ear` members, respectively, inasmuch as the front member is vseen as superimposed on the rear member when in osition upon the garment.

aid plates are disposed in latwise abutting relation for slidable movement longitudinally upon one another, and in order to prevent lateral movement therebetween-` the sopropposite end, or, as seen in Figures 1, 3, and i 6,'7, the front plate 3 is: provided with a` cross-bar 8 and thereby formed-with parallel slotted openings 9,710, the latter being preferably wider than the former; Integrally formed with said intermediate cross-bar 8,

Vloo

los p' such` ends must be sprung apart slightlybe- 'foretheh clasping member can be `snapped Y bars. The hook ofthe front plate 3 projects through the intermediate or vcentral open# ingv 11'?- of the rearpl'ate 4, its bill 12A being is a prerilblly Shaped hook, the Shank or neck 1l' ot which, the two plates `3, 4, being in flatwise superposed and slidable relation, is bent to extend somewhat into the. wider opening and then bent back and spaced from the rear face ofthe plate Swith. the bill r or head 12 of the T-bar extending endwise of and substantially parallel with, and disposed in a plane spaced transversely from the plane of the plates, as best `seen in Figure j4. "L The. rear plate' fr is formed with a spaced pair olf intermediate! cfross-barsf13, 14, and thereby provided adjacent'the cross-barst,

e 7, with a pairofl parallel `relatively narrow,

transversely orlendwlsef extending slots 125 and? 16, and af central' preferably Widerf slot` 17` betweenl said- -intermediate pair of crossdisposedi parallelf` relationtosaid plate,

-Withsufficient space therebetween to permit i offfa clasping member to stra'ddle said- `bill ina manner` about to be described. The shankorneclr l1 ofthe hook also forms a` stop toA limit relative movement loiigitiid'iinallly'` of? :the plates hoth directions.

Such clazsping member C is 4preierahly of the form `bestseen in` Figure 5 `andyas therel shown, isgprovidedjwith an end crossbar 18,*Wherebyfthei same may- `be secured `permanently torone end of the band `o r web 11, andi is .also provided with ya pair ofinte` gral, transverselfy7`v spacedl andV lon itudinal- 3 5 `ly-extending prongs 19, which are entback upon themselves to provide a space therebetween and the surface oi the clas'pin plate substantially equal" to' the thickness of l the imiterial` out 1 off Which the` rear plate 11 is constructed. The transverse spacebetween-the prongs is substantially equal to the width of the 'shank .11 ofsaidhoolr,` whereby, Whenthe elasping; membel C `is arrangedfsoitliat its prongs 19 straddle both ends olthe 'hoolohead 12, there will lbe Y large bearing surface 4between "the, two) elements, but there `Will be` no play between said membersi'n-a transverse direction. The prongs 191are also preferably `provided :With
