IMPROVEMENT 11\1 BUCKLES.

Specification forming art of Letters Patent N0. 167.947, d21ted September 21, 1875; appliea.tion filed j Feprumy 5, 1875.

T0 all whom z't mag; concern:

Be 1't known that I, DWIGHT L. SMI'1H, of Waterbury in the eounty 0f New Haven a-nd State 0f Conneetieut, have invented 21 new Buckle; and I de hereloy deelare the following, when taken in eonneebion With the accompzwying drawings and ehe letters of referenee marked there on, 1:0 be a, full,-clear and exact deseription 0f the same, and whieh said drmvings constitute parl: of this specifiea- Heretofore it has been the usual praetice t0' construet t-he body-hla-nk with an ear projecting f101n euch side, t0 be turned up, 211111 the ends bent inward t0 l'0rm the trunni0n's f01 the lever. This neeessitates very short 01 right-nngular bends in the eams. In doing this, unless the meta.l he 1300 soft f0r 21 dumble bnekle, many blanks will bedestroyed by the breaking 0f the ears in hending. Again, in clamp-buckles l;here is 110 allowanee f0r V21- ria.ble thiekness 0f suspenders.

The ob jeet of this invention is t0 ohviate these diffieulties, and ab the snme time produce z1 strenger buckle.

Theinventi0n consists in thepeenliar meth0d 0f forming the trunnions upon the body, as more fully hereinafter deseribed. 4

The blank f0r tl1e body is cut in ehe usual manner, freue suita.ble sheel: metal, and et the form seen in Fig. 3. This is substa.ntially the usual f01111 with this important diffiarence: The armes a 2113 each side 0f the body are formed hy euts d, and up0n the inside of these 211111s the trunnions e, all in the same plane. Then the arms a are turned upwa.rd es clenoted in Fig. 4, 130 bring the trunnions 110 the required elevation above the base A, 211111 Without bending the trunnions 01 forming sharp angular bends in any part; whereas, in the usual construetion, the blank is eut es in Fig. 7, with laterally-projeet-ing armsf, anc1 trannions 0n the end. These must be bent up and over, es seen in Fig'. 8. The lever B is applied t0 the trunnions in the usual manner.

By tln's improvemenl; Ehe trunnions are 0011- neeted to the b0rly below, leaving the base A free above tha-t p0int; 0f conneetion, and es the material of wl1ieh the huckle is made is elastie, it; follows thal; lle base A will yield as the lever is brought t0 bear up0n tl1e suspender 0ver the plate, and thus aeeonnnodate different thicknesses 0f material.

This eonstruetlon requires less metal tha.n the 0ld, es the width ot' the blank, as seen in Fig. 3, 1's lese than that 0f the 0ld as seen in Fig. 7,

In order t0 afford greater faeility for tueking the end 0f the suspender through the slit nin the plate, tha.n ean be when the parb A above the slit n is in the same plane es the p2nt bel0w, as in tlie usual consuruetion, I- depress the base A byfistriking lt bel0w rhe ends m, as seen in Figs. 5 and 6, the depression being al00ut equal to Ehe thiekness 0f the snspender; henee the parl: o1 bnse A will lie flal; up0n the back 0f tl1e suspender, and Ehe part D helow will lie flat upon the freut without making 21 bend in the suspender ab lhe slit.

l. A bnckle-frame, hafingthe arme afonmed lhe1eon by transverse euts d, with the inw-ardly-prqjecting trunnions e, as deseribed.

2. In a bnckle-frame; substantiamlly such as deseribed, the base A, struck below the plane of the par't D, substantially as and f01 the purpose specified.

suhstantially DWIGHT L. SMITH.
