Similarletters indicate like parte, A' y The object of theinventon'is to errungen-spring foropening shears insueh a. manner-'that it will be simple, .flur-nble, and Vnoi: interfere with the hand when using the 'sl'ienrsnV n In shenrs, A, of nydesired form, I mnke the bolt b, iig. 2, somewhat larger than usual,with a thread,`c, on one end,`a.nd over the head, dLI plaise a'brond cap, 'e,rigs. 1 and 2, all, however, melde in onepiece. In t'lle side of the bolt, near the end, is a. slot, h, made to receive n eorrespOnding-stud in the under blade Ic of the shea-rs. The'bolt being in place, -it issecured hy un o'rilinnry nut. Through 11n-opening in the head d is passed n coibepring, o, figs. l'and 2, which is wound around the head, its otherend being curved so as toi-est against the shoulder n on the upper blade s of the shears when the same are opened. 'It is evident that as soon as the V pressure used to bring the blades Atogether is removed, the tension of the spring will canse them te open nr once, the slot in `the bolt and its tud preventing thebolb from .turning Ol" coursetliis spring and boli: maybe' appliedto oflle instrument-s than shears, in fact lo all which have the scissors-movement; consequently I dO- `-not limit myself to'his purtipulnr instrumen-in the use of my invention.
What I clairnas my invention, and desire to seeureby Let'ltersPntent, is- The slotted-bolt l, wlith'ite cnpe, spring o, and shoulder n, all in combination; when rrangerl in relationto Veavelx other and the blades of4 the shears, substantially es nndfor'the purpose specilierl.
