BUCKLE.

SPECIFICATION forming part of Letters Patent No. 727,992, dated May 12, 1903.

Application led August 26, 1902! Serial No. 121,021. (No model.)

To all whom it mayconcern:

Beit known that I, DONALDM. MCLEAN, of Boston, in the county of Suffolk and State of Massachusetts, have .invented certain new and useful Improvements in Buckles,of which A further object is to provide such a buc-A kle. which will enable an ordinary padlock to be employed without risk of breaking the padlock or parts of the buckle in use, due to the padlock being struck by any external object.

To these ends the invention consists in the construction substantially as hereinafter described and claimed.

In the drawings, Figure lrrepresents a plan view, and Fig. 2 a longitudinal section, of one embodiment of the invention. and 4 represent views similar to Fig. 2, but each illustrating a different embodimentvof the invention. Fig. 5 represents a perspective view of the form of buckle shown in secy -is concerned. Inthis form, however, the portion in Fig. 3.

The same reference characters indicate the saine parts in all the figures.

Referring first to Figs.l and 2, the frame of the buckle is shown as of an ordinary type having side bars a and cross-bars b, c, and d, respectively, the cross-bar c serving as the means for attachment of one end of a strap a: in a common manner, the cross-bar d being that underneath which the free end of the strap is passed, and the cross-barb forming a loop to confinerthe end y of the strap. In this form the rigid tongue e consists simply of an arm projecting upward from the crossbar c and integral therewith and preferably at an angle toward the cross-bar CZ. The outer end of the tongue e is formed with a perforated enlargement f to receive the hasp of a padlock g, which latter may be of the ordinary typ'e and is represented somewhat conventionally. It will be observed that the outer end of the tongue projects out of the Figs. 3.

jeither as shown in the drawings or may swingv over to rest upon the buckle without bending `or breaking the padlock or its hasp or any portion of the buckle.

The form of buckle shown in Figs. 3 and 5 differs somewhat from the form j ust described in that the tongue e is shorter and thicker and formed with a more pronounced enlargement fand also in that the cross-bar b is designed to be connected with the strap A holdingloop fr is shown in this figure for the end of the strap y. In each form shown the enlargement of the tongue is such as to form a shoulder h at the back thereof, said shoulder engagingl the top of the strap y at the end of the slot or hole in the latter, and thus preventing the strap from slipping 0E fromthe tongue whether a lock g is employed or not. The form shown in Figs. 3 and 5 is particularly serviceable in this respect, as the tongue inclines somewhat rearwardly.

In'the form represented in Fig. 4 the construction is somewhat similar to that shown .in Fig. 2 in so far as the rigidity of the tongue tion ofthe buckle back of the cross-bar c is omitted, thus simply doing away with the metallic loop for confining the strap end. In this form the tongue is not integral with the cross-bar of the buckle, but is preferably riveted to it, so as to be practically as rigid as 'the other forms shown.

The cross-bar (Z of the buckle may be pro- `represented in Fig. 4.

`In each form shown the construction is such thatthe' padlock may swing freely over, so as to rest either forward or back of the tongue, without liability of injuring either member or the connection between them, and when-it vvided with the usual antifriction-sleeve h, as p is not desired to lock the strap the padlock may be entirely removed and the buckle then used in the ordinary manner, the shoulder at the back of the tonguebei'ng ample to prevent accidental displacement of the strap;

As will be readily understood, a chain might IOO be substituted for the strap, if desired, Withenlargement may swing forward or back on out departing from the spirit of the invention. the buckle.

In testimony whereof I have affixed my sig- I claim- A buckle having a rigid tongue provided nature in presence of two witnesses. 5 with a perforated enlargement at its end, said DONALD M. MCLEAN.

enlargement projecting out of the plane of the cross-bars of the buckle, whereby a padlock having its hasp in the perforation of the Witnesses:
