I, J uns 'l. Bknss'rsso, of Peabody, Vin the county of -Essex sind State ot' Massachusetts, here invented. certain improvements in Curriers loois, oi which the Figure 3, a cross-section on line o d? of l.A

'1 herod E passes through the handle and through fthe two 'parte ofthe slm'nk,eud is secured Ain place by t'heiiut E, thus holding,r the eross-handle firmly onto the cstock.

'lhe ordinary n 'iethod of fixing this cioss-h'andle in `the knife in common use is to allow the shank to projeetthrongh the eross-haudle, with a unt bywhieh it is held on. Besides being a very imperfect method of xiugthe handle, the nut is inconvenient to the work\' man on account ofehafing the hands.

".lhel two arts ofthe stoek nearest the eross-handle nre made so V at the line of' separation:between thetwo parts is at right angles with the liaiseupon which the blades are placed, forming a shoulder-joint, so that in yworking,r with it the. parts hear one against the other, to hold the two parts of the stock in a parallel posi tion and prevent one part slipping by the other. This joint is shown in iig. 5.

Ilhe other end oi' thestock is secured by a ring, G, which, by means of a leftnand screw-thread, binds this end ofthe stock together.
