TO ALL WHOM IT MAYCONGERN:

Be it known. that H. P. BALL and A. L.

' Inthe annexed drawings, making ,part of this specification, A A. represent the handles of the shears, pivoted together at g, with the jaws BBformed-ou their forward ends. These handlesv with jaws formed upon them are made of malleable iron, or any other suitable material. The inner faces of the jaws B B are provided with recesses, into which are fitted the steel blades or knives C C, These kniveshave cutting edges, and are pivoted to the jaws B Blnear their forward ends by means of screws lat e e. The heels of-these knives are stationed at any desired point, or moved by means of set-screws d CZ which act against their back edges. The inner ends of the knives C C are bevelled, as seen, from a to x, so 'that when a' screw is inserted in the jaw, 'as seen ,at a,

the under side of the screw-head will fit the bevel of the knife. The screws a a are for the purpose of station?.

blades C C may be adjusted upon the'jaws as fast as said blades wear away on their cutting edges by use. To

It will readily be seen that by this arrangement and construction the 4change or adjust the blade, the screws a a are loosened, and the set-screws d d turned forward as far as it is desired to set the said blades up at their l'heels. The screws a a are then tightened again, and the blades are held fast in the desiredposition. When the knives or blades wear out the old ones can be replaced by 'new ones.
