EDlVARD R. PALLEN, OF PHILADELPHIA, PENNSYLVANIA.
MILLING-CUTTER.
SPECIFICATION forming part of Letters Patent No. 447,900, dated March 10, 1891.
Application filed September 12, 1890. Serial No. 364.756. (N0 model.)
To all whom, it may concern:
Be it known that I, EDWARD R. FALLEN, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Milling-Cutters, which improvement is fully set forth in the following specification and accompanying drawings.
My invention relates to improvements in milling-cutters; and it consists of a cutterhead having peripheral jaws and novel cutters, substantially as hereinafter described.
It further consists of the combination of parts hereinafter set forth.
Figure 1 represents a partly side and partly sectional view of a cutter-head embodying my invention. Fig. 2 represents a face view of the cutter-head with mandrel. Fig. 3 represents a perspective view of a bit or cuttingtool adapted to be inserted in said head.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings, A designates a rotatable cutter-head which may be employed in milling or any other similar purpose, and which is provided with a series of slots B in its periphery C, dividing the said head into a number of jaws D. Between the said jaws and the back thereof are the screws E, having seats in the adjacent sides thereof and accessible at the periphery of the head A. It will be seen that when the bits F are in position and thescrews properly rotated in the conical and countersunk opening in the jaws with which the screws are in contact the said jaws are forced apart, whereby the parts thereof on opposite sides of the bits are pressed against the said bits, thereby firmly clamping the same in place. The bits are shown serrated 011 one side, so as to more reliably prevent the slipping of the same in the head when in use; but both sides may be serrated, as desired. It will also be seen that according to the distance that the bits are inserted in the openings G the diameter of the cutter is adjusted, the screws at all times keeping the said bits securely in'place. The bits are adapted to be inserted in the jaws from the sides thereof, the serrations preventing any slipping or movement radially of the same.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. An expansiblecutter-head having openings for the bits and means intermediate of said bit-openings for clamping the bits in place, said parts being combined substantially as described.
2. Arotary cutter having ahead with slots in its periphery, forming jaws, the latter having openings therein for the bits, and screws provided with seats in adjacent sides of the EDlVARD RQPALLEN.
