T all whom it may concern:

Be it known that I,.FRAN I, 'MoGosvm', a citizen of the United States, .residin at Reddin in the county of Shasta and tate of Cali ornia, have invented new and useful Improvements in Corrugated-Iron shears, of which the following-is a specificat on.

This invention relates to shears which are particularly adapted for. cuttmg corrugated The object of the invention is to provide a simple and substantial and easily operated pair of shears, which shears are constructed with the object in view of preventing the corru ated iron from becommg flattened while ing cut, and which will a so prevent any slipping of the iron with relation to the knife and cutting e Further objects w1l hereinafter appear.

The invention consists of the parts and the construction and combmation of parts as hereinafter more fully described and claimed, having reference to the accompanyin drawings, in which %igure 1 is a plan view of the shears showing a portion of the knife broken away. Fig. 2 1s a side elevation of the shears. F g. 3 is a cross section on X-X, Fig. 2. F1 4 is a perspective view of the removab e spacing plate.

Referrmg to the drawings, A and B ndicate a pair of plates between which 1s pivotally. mounted, as at 2, a knife or cutter C. The 0 posite ends of the plates are held apart y a spacing late 3 and secured together by a bolt 4. neof the plates, as A is in this instance provided with a pair of raised portions 5 and a corresponding'intermediate depression 6, said raised portlons and recess being of a contour which will conform with the corrugations usually formed in corrugated iron. The plate A is also provided for the purpose of orming a shearing edge for the knife C.

- In operation when it is desiredzto cut a plate of corrugated iron crosswise of the corrugations, it is accomplished by. sli ing the plates A and B under the iron unti the raised portions and recess 6 register with the lower contour of same. The knife C is then depressed by the handle 7 and is thus. caused tocutthe plate on the lined the corrugated cutting e formed on the plate A. The corrugated e ge thus formed an the plate prevents the corrugated iron from flattening out while being cut and, furtherwith .re atiou to the e and cut edge. By referring to Fig. I'it will be s de n that "the knife is made slightly ta in bemg' narrow at the ivot point and near thehandle. T peculiar shape is provided for the pulxose of spreading the severed ort1 on of e iron so as to prevent an mdm action when the knife is returne The pivot member 2 constructed as here shown not only serves the purpose of a p1vot for the knife, but also acts as a clam to secure the forward ends of the plates and B. The spacing plate 3 may be changed wlth thicker or thinner plates, when desired, for the purpose of widening or lessenmg the space etween the plates. l

A dev1ce constructed as here shown is simple and compact in construction and is particularly suitable for cutting corrugated iron. I wish it understood however, that the knife 0 ma be. rovided ting edges 8 an -9, t e edge -8 being used in con u nction with the corrugated cuttin edge, while the cutting edge 9 may be use with the opposite side of the plates by inverting the a paratus, when it is desired to cut a, straig t plate, The lower face of plate B will'then act as a cutting edge. The shears are thus applicable for various purposes, such as cutting heavy straight plates or corrugated surfaces.

The materials and finish of the several parts of the shears are such as experience Having thus describedmy invention, what I claim and desire ent isv 1. A shearing tool including a pair of to secure by Letters Patmor e, revents any of the plate with two cut spaced plates arranged in side by side relation one of which has 'a straight uninterrupted shearing ed and the other of which has a corrugated-s aped shearing edge, and a knife pivotallymounted in the space between said plate and servi to hold the latter s aced at one end, sa1d knife bein receiv in the space between the plates an having a shearing edge onleach side thereof where y one shearing edge of the knife c0,-

to allow the shearing edges of the blade to oooperate with either the upper or lower re spective shearing edges the plates.

In testimony whereof I have hereunto set 16 my hand in the presence of two subscribing witnesses.
