SLIDE BUCKLE v Filed Nov. 10, 1959 UNITED STATES P-TENT OFFIQE SLIDE BUCKLE George Henry Elwell, New Haven, Conn, assignor to Eastern Tool and Manufacturing Company, Bloomfield, N. J., a corporation Application November 10, 1939, Serial No. 303,865 4 Claims. (01. 24-200) This invention relatesto improvements in slide ends of the cut-metal edge 1 the metal at these buckles and more particularly to'slides that are points is so formed (following the cutting procadapted for use in connection with a longitudiess) as to provide ofi-set stop-projections 8 nally folded strap threaded therein to provide a adapted to engage adjacent rigid cut-metal 5 loop below theslide from which a metal button edges 5A of the sheet body I for the purpose of 5 loop may be suspended, arresting the tongue 6 so that it cannot be forced The objects of this invention are to provide a out of the plane of the face 2 in the direction slide buckle with a strap-binding element havof the interior of the marginally cupped formaing a more uniform binding grip regardless of tion of the sheet body I. The off-set projection the particular thickness of the strap threaded 8 as exaggeratingly illustrated by the Figure 6 10 therein, and to provide a slide buckle with strapis of conventional form only but, with a sufthreading apertures of which one is normally of ficient gauge of metal, a proper forming stroke less short diameter than that of the other, but adjacent both edges of; a raised tongue 6 should having a yielding strap-binding element capable so spread and form the metal at these points ofadjusting the aperture; to receive therein a as to provide suificient projections 8. Instead 15 strap of any thickness that can be passed of providing the tongue 6 withthe stops 8, propthrough the other aperture. er stops 5 5 might just as well be. provided In the accompanying drawing the Figure 1 is by the metal of the body at the converging open a face view of the improved slide; Figure 2 is cuts 5 5.

The folded end of the strap is Referring more particularly to the drawing then inserted into the aperture 3 and, as the the slide buckle thereby illustrated preferably is ed S ap above and below the thus mount- 30 intended to be struck up from sheet metal, or ed Slide is pulled taut. the portion of strap in other sheet material, in one piece but, if desired, the Slide s drawn Close to the face 2 and down it may be made in any other manner in two or upon the ed 1 0 t e gue 6 which under the more pieces and assembled. The sheet body I pu g strain is forced toward its normal position of the slide preferably is marginally rounded in the Plane of the face 2 0 the Sheet y 35 rearwardly to provide a, rigid body and to give the thickness of the doubled strap preventing its better facial appearance illustrated by the full return to normal position, as illustrated by Figures 1 and 2, although so far as use is com the Figures 3 and 4. Thus the wedged contact cerned the body may retain its fiat condition as of edge 7 0f the tongue 5 With the oubled 0 when cut, from the heet material. AS i11us strap 15 such the slide iS fixed theretrated by the Figure 1, the face 2 of th Sha i to and can be adjusted to different positions along provided in its lower portion with the horizontal the strap Only y loosening d pu g away aperture 3 of such length and short diameter as that Portion 0f the S p lying a t t e face 2- will permit a double thickness of strap to b The Figure 5 illustrates in cross-section the 5 inserted freely therethrough, 1 t upper porsame structure as above described and as illus- 5 tion of face 2 there is provided the horizontal trated in the drawing ut is t ere shown in aperture 4 f less short diameter tha t t of connection with a doubled strap of less thickt lower aperture 3 t hi h t is d paralness than that first above described, this doubled lel. Immediately below the aperture 4 and comstrap being similarly threaded into the slide, but,

municating therewith are the companion open as the doubled strap is drawn tightly therein, 50 cuts 5-5 converging toward the aperture 3 so the pulling strain forces the tongue 6 toward that thereby there is provided between the open its normal position thereby tending to restore cuts 5-5 a resilient tongue portion 6 of which the normal diameter of the aperture 4 and thus the extremity cut-metal edge I is a cut-metal crowding therein that portion of the doubled as edge of the communicating aperture 4. At both strap with which its edge 1 contacts and, if the doubled strap thereby is sufilciently crowded into the aperture 4, the off-set projections 8 engage their adjacent edges 5A and hold the tongue 6 against swinging out of the plane of the face 2 of the sheet body I toward the cupped interior of the slide buckle.

From the foregoing it will be recognized that the improvement herein set forth provides a slide buckle with a novel strap binding element that is adapted for self-adjustment in its application of a substantially uniform grip upon a strap threaded into the slide without any special regard to its particular thickness. Of course the applicant is aware of the previous art which discloses spring tongues integral with the structure but, in each instance, the tongue there shown abuts a bar separated therefrom only by an open out such as appears upon either side of the tongue. If it were not for the aperture' l located above the edge I of the tongue 6 a strap of any great thickness would so deflect and dis"- tort the forced positionof the tongue G-that that portion of the strap 'lyin'g'over'the tongue 5 would be so projected and humped as tobe'obje'cti'onable to the wearer.

I claim:

1. A slide buckle comprising a' sheet-metal structure, cut-metal edged apertures in a common plane and of different widths with which the structur'eis' provided for' threading a strap therethrough, companion open cuts intermediate the apertures and communicating with the aperture of lesser width to provide a resilient strap-binding element integral with the structure and normally withinthe plane of the aperstructure having a rectangular margin receding from the plane of the sheet-metal to provide a rigid frame, spaced and parallel cut-metal edged apertures of difierent widths with which the structure is provided in the plane of the sheetmetal for threading a strap therethrough, companion open cuts intermediate the apertures and communicating only with the aperture of the lesser width to provide a resilient strap-binding element in the plane of the apertures and integral with the structure, a cut-metal edge of one of the apertures providing the strap-binding edge of the resilient element, and stop means provided by the structure adjacent the open cuts to arrest the swinging movement of the resilient element out of the plane of the apertures in one direction;

3. A slide buckle compnising a sheet-body frame, a pair'of apertures in a common plane providedby the frame, a resilient tongue element'integral with the frame and normally presenting a straight edge to, and thereby determining the width of, one of the apertures, and stop means with which the buckle is provided to arrest the movement of the tongue edge out of the plane of the apertures in one direction.

4. A slide buckle comprising a one-piece sheet-metal structure, a flat face with which the stru'cture'is provided, a rearwardly receding marginbounding said face, a pair of spaced upper and lower apertures in a common plane and extending across said face to provide openings for threading from the rear a strap therethrough, a tongue integral with the structure intermediate said apertures, the free extremity of the tongue being normally at rest in said plane within, and determining the width of, the upper aperture, and means by which in the insertion of a strap into said upper aperture from the rear the deflection of the free extremity of the tongue is limited to a forwardly direction out of said plane.

GEORGE HENRY ELWELL.
