IMPROVED CUTTING-TOOL.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, GUSTAV L. JAEGER, of 178 Fulton street, New York, in the county of New York, and in the State of New York, have invented a new and improved Adjustable Cutting-Tool; and Ido hereby declare that the following is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being'had to the accompanying drawing, forming partei` this specification, in which drawing- Figure 1 represents a longitudinal central section oi' this invention.

Figure 2 is a partial side elevation of the same. i

Figure 3 is a front view of the same.

Similar letters indicate corresponding parts. i

Y This invention relates to a. tool with an adjustable tooth and bearing, secured in a stock, which is so arranged that it can be secured to theend of the spindle of a turning-lathe, or in an ordinary breast-brace. By adjusting the tooth andibearing in the stock, pieces of metal 'wire or other pieces-of metal can be turned down at their ends to any desired size, withA the greatest ease and accuracy.

A represents a tool-stock, whiclris provided with guides, a, to receive the tooth B and the-bearing C. The tooth B is adjustable by the set-screwb, and the bearing C may also be made adjustable by a set-screw, c, or in some`cnses, where the tool is to be used for work of uniform character, said bearing may be rigidly connected to the stock. 'The stock A is provided with a socket, d, by means of which it can he secured to the spindle of a turning-lathe, as shown in fig. `1 ofthe drawing, or which serves to receive a square shank, e, as shown in tig. Q, said square shank being made of such a shape that it can be conveniently introduced into an ordinary breastbrace. Aftersnid stock has been secured to the lathe-spindle, or in the breast-brace, the tooth B is adjusted according' to the thickness to which the wires or other pieces are to be turned down, and by pressing said wires or other pieces against the tooth, orby pressing the tooth against the work, the desired cii'cctis produced. The ends of wires or other pieces of metal can thus be turned down with the greatest case and uniformity, and the. tooth can be easily taken outand sharpened whenever -it may become dull. It' desired, the tooth may be made of such a shape that it will produce a round instead of a square shoulder.

What l claim as new, and desire to secure by LettersPatent, is-

'lfhe combination of the slotted and shankcd stock A, guide-frame with cutter, B, bearing C, and screws b c, all arranged'substantially as set forth.
