should the latter become worn or broken.

In providing the projecting flanges or shoulders 1 and 8 upon each pivot end of a handle adapted to receive the correspondingly shaped end llof each blade, and by forming upon the relative parts of the handles and blades cooperating projections and recesses therefor, it is obvious that when the pivot bolt or screw l0 ex-' tends therethrough, a. rigid connection. is estab-. lishedibetween'each handle and its blade. Small set screws. l4 are: employed for attaching each blade 'toits'handle, but the set screws would not be capable of establishing a permanent and rigid connection between the blades and the handles therefor, if itwere not for the projecting flanges.

or 'shoulders and I, and the cooperating engageable projections andrecesses l3, l4 and l8"; 19,

respectively. Therefore, it will be seen that the set screws I4 are only connecting members between each blade and its handle, whereas the real shearing forces between the blade and its handle are transmitted through the shoulders or flanges and cooperating locking projections and recesses.

Manifestly, the construction herein shown is capable of considerable modification and such modifications as come within the scope of my claim, I consider within the spirit of my inven- I' claim:

A pair of shears comprising pivoted handle members, the pivoted end portions of said handle members being enlarged and having each a recess therein, blade members the inner ends of which are fastened to conform with the recesses in the enlarged ends of the handle members and having two faces thereof to lie flush with corresponding walls of said recesses, a detachable pivot member extending through pivot openings formed in the enlarged pivot ends of said handles, elongatedprojections formed bodily with the normally inner surfaces of. the pivoted ends of said handle members and disposed parallel to the longitudinal axis and abutting, each with one end on the pivot or the aperture thereof, said blade members having each an elongated slot for receiving the projection'formed with its companion handle member and said detachable pivot member and set screws arranged at the opposite sides of said detachable pivot memberfor detachably connecting said blade members to the pivoted end portions of said handle members.
