IMPROVEMENT IN CUTTER-HEADS.

Specication forming part of Letters Patent N o. l 88,771, dated March 27, 1877; application filed December 27, 1876.

ATo all whom it may concern Be it known that I, MYRON T. BoULT, of

Battle Greek, in the county of Calhoun and State of Michigan, have invented an Improvement in Gutter-Heads and do hereby declare that the following is such a full, clear, and exact description thereof as will enable others skilled in the art to which it pertains to construct and'use the same, reference being had to the accompanying drawings, forming apart of this specification, and to the letters of reference marked thereon, similar letters indicating corresponding parts in the dii'erent iigures.

My invention relates to a cutter made of solid steel, having double cutting-edges, or edges which will cut while the tool' is revolving in either direction, right or left, and which annexed drawings, in which- `Figure l is a perspective view ot' the cutter; Fig. 2, a longitudinal section; Fig. 3, an end View, and Fig. 4 a modification of the same. l A represents the cutter, made of a single solid piece of steel, turned to suit any desired, configuration of molding, and having double cutting-edges, a and b,vwhich allow it to cut while revolving in either direction, right or left. This method of construction is rendered .necessary on account of the tool being made reversible in the tool-stock ormandrel, and is of great service in allowing the tool to cut with the grain of the wood at all times, as, by

applying a reversing motion to the mandrel, the cutting or rotating movement ot' the tool may always be made to correspond with thev direction of the grain ot' the wood acted upon, thus insuring smooth work. The method elnployed by me to give the .proper form to the 'periphery of the tool, in order to insure per- In forming' the cutter a stem or shank, B, Y

is produced at both ends, either of which may be inserted in the tool stock or mandrel, the opposite end serving as a guide to the work.

These stems are turned from centers in the ordinary manner, and are therefore concentric to the periphery of the cutter and circular in section, so as to lit them for entering the socket of the tool-stock, or to act as guides for the tool.

Having thus described my invention, I claim as new,and desire to secure by Letters Patent ot' the United States, the following:

A molding-cutter constructed with a shank or stem on each end, either ot' which may be used to hold the cutter or guide the lumber to be molded, and provided with double cuttingedges, as and for the purpose specified.

In testimony whereof' l have hereunto afxed my signature this 31st day ot' October, 1876, in presence of two witnesses.

MYRON T. BOULT.
