after "e13 Patented Nov. 18, 1930 UNITED STATES THOMAS S. SPEAK, OF NICHOLS, FLORIDA BUCKLE Application filed February 7, 1930. Serial No. 426,606.

This invention relates to buckles. It is of particular utility upon overalls and like garments intended for heavy use, but it will be found of utility in any relation where a fabric strap is to be quickly clamped in adjusdted position, with respect to the buckle b0 Further objects and advantages will be set forth in the detailed description which follows.

In the accompanying drawing:

Fig. 1 is a face view of the buckle.

Fig. 2 is a longitudinal sectional view upon line 22 of Fig. l.

Fig. 3 is a transverse sectional view upon line 33 of Fig. 1, and

Fig. 4 is a side view of the buckle in open position.

Like numerals designate corresponding parts in all of the fi ures of the drawings.

It is one of the ob ects of the present invention to provide a buckle which may be stamped from a single piece of sheet'metal.

In the particular embodiment of the invention that I have chosen for purposes of illustration, I stamp out a piece of metal in such manner as to form a base A, and a tongue B. The base A comprises the three longitudinally extending bars 5, 6 and 7, which are united at their forward and rear ends by the transverse bars 8 and 9. The forward transverse bar isrolled inwardly to form an eye 10 for a swinging bail 11. The tongue B is formed as an integral continuation of the rear transverse bar 8, and it extends longitudinally of the base and overlies the center bar 6. The

' tongue B is, preferably provided with inturned edge portions 12 and 13, which aid in crimping thematerial to be held, over the center bar 6.

In the embodiment illustrated, the base A may be sewed, riveted, or otherwise secured to a garment, here illustrated as the upper corner portion of an overall flap 14;. The shoulder strap is indicated in dotted lines, at 15, and after it has been passed downwardly between the tongue B and bar 6, the free end of the tongue is forced down upon the roll 10 and bail 11 is swung inwardly over the free end of the tongue to hold it in locked such as have commonly been employed in fastenings of this sort. The buckle is of very simple and economical construction, and it may be stamped out of sheet metal with great rapidity and at small cost; it forms a very secure fastening device and it provides a.

buckle by means of which the strap may be adjusted to the desired position, almost instantly.

- While I, preferably, form the tongue in one piece with the base, leaving the connection between said tongue and base in the nature of a spring connection, it is clear that many of the advantages inherent in the structure will be present, whether the tongue is made in one piece with the base, or made in two pieces and secured to the base with a conventional hinge. Therefore, it is to be understood that the term hinged as used herein, is to be given a broad construction.

To facilitate the sewing of the buckle to the garment, the side bars are perforated to any desired extent, as indicated at 16.

It is to be understood that the device of. the present invention is not limited to the pre- ,cise construction set forth, but that it ineludes within its purview whatever changes come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is 1 A device of the character described, comprising a base consisting of a longitudinally extending center bar, opposite side bars and transverse end bars, of a hinged tongue extending longitudinally along and over the center bar and carried by the rear transverse bar, and a swinging bail carried by the front transverse bar of the base, adapted to swing inwardly over the free end of the tongue, said tongue being provided with inwardly projecting flanges along its opposite edges, which project over but lie in spaced relation to the center bar.

2. A device of the character described; comprising a base consisting of two longitu- 5 dinally extending -side bars, an intermediate center bar, connecting front and rear transverse bars, an integral tongue projecting forwardly from the rear transverse bar and lying above the center bar, inwardly extending 1o flanges carried by said tongue, which project inwardly upon opposite sides of the center bar but lie in spaced relation thereto, a rolled portion formed upon the front transverse bar, and a bail pivoted in said rolled portion and adapted to swing inwardly over the free end of the tongue, as and for the purposes set forth.

3. A device of the character described, comprising a base, consisting of a pair of side bars and a center bar, of a tongue hingedly connected to the rear end of said base, securing means for the free end of the tongue, carried by the forward end of the base, and members carried by the tongue fitting over the sides of the center bar of the base, the side and center bars being provided with inward- 1yl extending flanges along their confronting e "GS.

ii. A buckle bent from a single piece of metal to form a base portion and a tongue portion united with each other at one end, the tongue portion being materially narrower than the base portion and said base portion being cut to form a longitudinally extending 3 center bar, and a pair of outer side bars, the latter being provided with perforations by which said base may be secured to a garment, said center bar being provided with inwardly extending flanges and the tongue being likewise provided with inwardly extending flanges adapted to fit over the said center bar, and a securing means for connecting the free end of the tongue to the base.

In testimony whereof he afiixes his sig- 415 nature.

THOMAS S. SPEAR.
