IMPROVEMENT IN MOLDING CUTTER-HEADS.
Specification forming part of Letters Patent No, 125,765, dated April 16, 1872.
I, DANIEL STANLEY, of Cincinnati, Hamilton county, State of Ohio, have invented a 4certain new and useful Improvement in Frizzing-Bits, of which the following is a specification:
Nature cmd Objects of Invention.
M y invention relates to the class of frizzingblts or rotary cutters for wood-working maclunes which are adapted to reverse so as to present a cutting-edge in either direction; and
Description of the Accompanying Drawing.
Figure 1 is a perspective view of my improved cutter. Fig. 2 is an axial section of the same. Fig. 3 is a crosssection through the bits.
General Description.
A is the cutter-spindle, formed with a shank, a, for the reception of the bits, and screwthreaded at the end to provide for the fastening-nut. B is the inside collar or shoulder; C, the outside collar 5 and l), the nut used to secure the bits in place. E E are the bits or cutters, which are first turned out of one piece of steel to the required form and cut radially so as to form four bits, sufficient to supply two a, for a purpose hereinafter explained. Pivots i or pins F are fitted between the bits and collars on each side, the pins being half in the collars and half in the bits, as shown in Fig. 2, for the purpose of permitting the bits to oscillate circumferentially and thus to present a cutting-edge in either direction of rotation, the bore of the bits permitting this, being larger than the shank a. The bore, however, is not so much larger than the shank a as to permit great vibration, but, being but little larger, serves to prevent too great an oscillation, stopping the bits in either direction at a4 point when the bits have suiiicient clearance behind the cutting-edge, as shown in Fig.`3. When it is desirable to reverse the action of the cutter-head, the nut D isfslacked slightly', the bits thrown into the proper reversed position, and the nut again tightened.
Claim.
set my hand.
DANIEL STANLEY.
