IMPROVEMENT IN THE CONSTRUCTION OF SHEARS. w

The Schedule referred to in these Letters Pat-ent and making part of the same.

Be it known that I, JosEPH RYALs, of Terrysville, in the county of Litchfield, and State of Connecticut, have in'vented a new and useful Improvementin Shears; and that the following description, taken in connection with the .accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said improvement, by which my invention may be distinguished from all others of a similar class, together with Vsuch parts as I claim, and desire to have secured to me by Letters Patent.

This invention relates to a new and useful improvement in that :class of .shears which are constructed of malleable cast-iron, and have blades of steel welded thereon to form thecutting-portion.

The present invention consists in casting the handles, recesses, s'tops,.and bearings, in such a smooth and perfect manner that they can be fitted together, Without further grinding, filing, or fitting than that required to fit and'polish the steel portion of the blades.

In the accompanying sheet of drawings- Figure l is a side view of my invention, partly in section.

Figure 2, a section of the same, taken in the line a: x f1 1.

Sigmilar letters of reference indicate like parts.

A A represent the-two blades of a pair of shears,

and B B, the handles thereof.

These two parts are connected by a pivot or'rivet, C, and the handles B B,`near where the pivot or rivet passes through, are cast with recesses, in such smooth and perfect manner as to fit without'grinding or filing.

By this means a greatdeal of laboris saved in filing up the shears, after being cast, and in fitting the two parts together.

At present the handles are cast so that the snrfaces or spaces between the pivot or rivet C, and the steps or ledges c, work in contact with each other, and all to be iled and made perfectly true, in order that they may work freely over eachother. This is attended with considerable labor and eX- pense, so vmuch so, that innishing up a dozen pairs of shears, a Iile, Worth fifty cents, is completely used up or worn out. v

By my improvement, this labor and expense are nearly full y obviated.

I claim, in the construction of shears, with malleable cast-iron handles, having steel cutting-surfaces welded thereto, the handles, with their stop and bearings cast so as to t without grinding or filing, as set forth.
