. This' invention relates to improvements 4in scis'so'rs 'or shear s,',one of the objects of the provi e a. pairfof scissors ory shears in .whichone of, the blades is relatively stationaryifandzthe other relatively movable in action, and further to provide a construction. which affords a draw-cut with a high degree 'of leverage or cutting power in the operation of the blades,.a desirable feature in cuttingfheavy materials.

A further objectof the invention is to provide-a simple construction :torV attaining these ends,. to. provid' means for maintain. ing the blades in proper relation andJpre-- vent-ing their deviation from theinsproper.- lines 'of relative movement from wearand loosening of the pivots, and to provide a, construction whereby the lower blade Willi of which the following the material in cutting.

The arm 1() is pivoted by ascrew 11 passing througha countersunk lopening 12 therein to the blade 1 and inad- 'vanceofsaid opening is formed on its outer side with'aJ segmental recess 14 and its end .portion terminates in a partially circular tooth o'r projection 15.` The section 6 is proivfided. at. its .rear end with an arm or tang 16 lhaving at its forward end a diagonal slot 17 outer side to receive the 18 which passes through blade 1,.thereby pivblade. .-r .'Igherear end of the aim or tang 16 is proi'vith a reduced "portion or tongue 19 having a rounded end and which overlaps 10 and fits and moves This tongue is formed ihead of a screw arm 10, through which pivotall) connectis :formed with a thus forming a connection .easy relative pivotal mo- 'due strain and pim; 22.
