To @ZZ whom it mayoonoern.:

Beit known that I, GEORGE E. ADAMS, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in the Manufacture of Sheet-Metal Suspender-Buckles; and I do hereby declare the following to be a full, clear, and exact description of thel same, reference being had to the accompanying drawings, forming a part of this specification,

and to the letters of reference marked thereon.

This invention relates to improvements in the manufacture of buckles which are struck up from sheet metal and designed more particularly for personal wear, the objects of the invention being to provide an improved method of forming the pivots of the locking lever, whereby a smoothly operating and strong device is produced which will not catch or wear the clothing.-

Referring to the accompanying drawings: Figure l is a perspective .view of a buckle embodying my invention. Fig. 2 is a similar view of one end of the locking lever. Fig. 3 is a view of the locking lever with the pivots partially formed. Fig. 4 is a similar view be-` fore the formation of the pivots are started.

Like letters of reference in the several iigup of sheet metal preferably has an orna# mental front piece D', by means of which it may be operated, and a toothed edge D2 for co-operating with, and clamping the fabric against, the body portion to hold the parts in adjusted position. As ordinarily constructed, a simple projection of the thickness of the metal constituting the body of the lever is left at each end thereof, which being passed through the apertures in the ears on the body portion would constitute the pivotal connection between the two; but this form of pivotal connectionk is open to many objections and a number of more or less eiicient expedients have been devised for overcoming these objections, among which may be mentioned cap pieces on the lever itself which extend over the ends of the pivots outside of the ea rs and the ears themselves instead of being provided with apertures have been formed'with bearings struck out from the inside and forming simple projections on the outside. All such arrangements, however, have been objectionable because of the cost incident to the manufacture, or the assembling ofthe parts, or to the fact that the clothing of the wearer Was liable to be caught or worn. In my present construction, I propose to overcome these difficulties by doubling back the end of the pivot projections shown at G in Fig. 4 into the form of cylindrical, rounded end, pivots, as shown clearly at Hin Fig. 2, which rounded pivots fit accurately into the apertures in the ears, prevent all looseness or wabbling of the lever and present a smooth, even contour on the outside which cannot catch or Wear the clothing of the wearer and which, because of the extended, smooth bearing surfaces will not wear loose or allow the buckle to become rickety. I prefer to form these cylindrical round ended pivots H by first, striking the metal up to the shape indicated in Fig. 3 and then to the shape indicated in Fig. 2, that is to say, the metal of the projections at the ends of the lever is first bent into semi-cylindrical shape at right angles to the length of the pivots and is then set down by dies so as to form projec- -tions which will constitute the axis of the ICO with lateral projections, bending said `projections into semi cylindrical form at right angles to the axis of the lever and finally bending the said semi-cylindricalprojections down to form oppositely projecting cylindrical round ended pivots; substantially as described.
