Description

"piercing the fabric a second time 'andbearing againstand concealed beneath the by theb uckle is permanently fastened to the .mg- If preferred the buckle may be simply intransverse strip of the material of the same size as the prong, firmly underneath the buckle. 1

A foot press fitted with a suitable punch and die is commonly used to automatically fasten the pronged buckle permanently to the garment or other article, by clinching the prong, after the buckle has been placed at the desired position on the garment. The free end of the strap can then be fastened in the adjusted detachable position on the buckle by passing the strapend up' through one end slot, over the transverse bar and down through the other end slot.

in which the central slot 5 is the same length as the outer'slots, extending to the inner edges 8 of the sides 4 to which inner edge the two prongs 7 are based. 1 The strap 9 is pierced twice by the prongs, first downwardly when 'thebuckle is placed in position on the strap and a second time upwardly on bending the prongs outwardly and clinching the points against the under surface of the sides ofthe buckle.

In Figs. 5 and 6 the buckle is shown fastened to a garment. The prong piercing the fabric twice; first, downwardly after the garment issuitably placed under the buckle,

and then upwardly when the prongs are 'crimped outwardly. The strain on the v prongs is transverse and is distributed along theentire length of the fabric held under the prong. The crimping is preferably done on a foot press though a suitable plate and hammer suffices.

In Fig. 6, small holes at 12 are punched in suitable places on theside bars to receive and hold the points of the prongs on clinchdented at this point. 7

I claim as my invention and desire to be protected by Letters Patent:

1. Abuckle formed from a single blank, having sides and ends formingaclo'sed frame,

and at least one transverse bar parallel thereto connecting the sides and separated by slots from the ends, and provided with two prongs of substantial length, cut adjacent and paral- "lel tofthe transverse barand bent-downwards substantially perpendicularly and shaped and adapted to be entirely forced through a piece of fabric, when placed in position there on, and then to be bent through a'further angle, until the body of the prongs lie substantially parallel to the frame of the buckle clinching against its undersurface strips-of fabric extending from the base of the prongs to their 'points, these points under surface of the buckle at a substantial distance from the base "of thelprongs, whereor bars,

' until the points of the prongs take against Figs. 4 and 5, show an alternative form, r

the under surface o f'the sides of the buckle, so that a strap or garment on being suitably placed to be pierced downwardly by the prongs is onclinching the prongs upwardly pierced by the points and permanently held to the buckle. I

3. A buckle. formed out of a single blank having a frame consisting of two sides and two ends and two transverse bars forming two endslots'and one center slot, with two prongs cut transversely from the metal of the center slot based on and projecting from an extension inward of the sides opposite the center slot and positioned and adaptedto be further bent transversely and outwardly to overlap such extension.

4'. A buckle having sides, ends and a transverse bar separated by slots from the :ends'j" and connecting saidsides and provided with integral prongs cut from between the edges of the transverse bar and turned downwardly at points adjacent to said sides and adapted to be driven through material'to which the bucklev is, applied and turnedjup laterally beneath said'sides, thereby tof'asten the buckle to an article and prevent verticaland lateral movement of the buckle while 'conc'ealing'the points of the prongs;

5.-A buckle formed from a single blank having a frame of two ends and two sides f and a transverse bar dividing theinterior of the buckle into a plurality of slots and two sharp-pointed prongs of substantial length cut from the interior of the blank parallel to the ends of the buckle and projecting down ward substantially perpendicular to the frame of the buckle, and adapted, after penetrating a garment throughout the entire length of the prongs, to be'bent outwardly, and upwardly so that the point of each prong is harbored underneath'opposed sides of the buckle, thereby clinching a substantial trans verse strip of the garment and means for holding the loose end of a strap passed through the slots, in adjustable, de-

. tachable position thereon. 6. A buckle having a frame consisting'of sides and ends and at least one transverse flbar, separated by slots from the ends, and provided'with two'integral transverseprongs I thus fastening .the buckle permanently thereto, and having of substantial length out parallel to andad jacent the transverse bar andbent at their bases laterally downwards approximately 90 degrees, and adapted on being forced upward laterally to flatten underneath the buckle and to clinch a strip of fabric lying under and adjacent the transverse bar, thereby fastening the buckle permanently to said fabric.

A single-piece buckle having sides and 7 ends and two transverse bars forming two end slots and one center slot, with two sharppointedprongs cut from the metal of the center slot, parallel and adjacent tothe two transverse bars and based on the inneredges of the sides of the buckle, and bent downward therefrom and adapted to be further bent outwardly away from the center slot to lie under the sides of the buckle opposite the ends and a transverse bar extending from center slot. l r I ,8. A one-piece buckle having sides and sideto side dividing the interior of the buckle into two slots, and two oppositely disposed the under side of the buckle whereby the buckle is held in permanent, adjusted position on the fabric. a p

9. A one piece buckle'with a closed frame formed of two ends and two sides, and having at least one transverse bar, forming a-plurality of slots, and at least one transverse integral sharp pointed prong of substantial length cut parallel to the transverse bar and bent in such mannerat its base laterally until perpendicular to the plane of the buckle,

said prong being first forced through a piece of material, then bent laterally and upwardly to pass through the material a second time into engagement of its point with the underside of the buckle, whereby the buckle is anchored permanently in set position on the material. V

10. A method of fastening a buckle, having two sharp pointed transverse integral prongs projecting perpendicularly therefrom permanently to the body of a garment, consisting in firstplacing the buckle in the desired position onthe garment, then forcing approximate size of the prongs are clinched between the under side of the buckle andthe prongs, and finally upsetting upwards the points of the prongs, until they passthrough the garment a second time, and rest securely housed under the buckle.

In testimony whereof I aifix my signature.
