UNITED STATES PATENT OFFICE.
HENRY D. STOVER AND J. YV. BICKNELL, OF BOSTON, MASSACHUSETTS.
ROTARY PLANING-CUTTER.
Specification of Letters Patent No. 25,286, dated August 30, 1859.
To all whom 'it may concern.'
Be it known that we, HENRY D. STOVER and J AMES lV. BICKNELL, both of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Cutting Irregular Forms and for Similar Purposes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which drawings- Figure l, is a sectional elevation of a cutter head and the guard (J) combined. Fig. 2, is a plan of the same. Fig. 3, is an elevation of the cutter head, the guard (J) having been removed. Fig. 4, is a section of the same at A, B, and Fig. 5, is a plan. Fig. 6, is a sect-ion of guard (J) at C, D.
Our improvements consist principally in the application of the guard (J) as we will proceed to describe. The main part of the head (a) has a circular base and the screw (b) by which it may be attached to the arbor of the machine. From the circular base upward as shown in the drawing two sides are flattened to receive the cutting knives (c) and (d) and from near the upper end of the knives upward it is rounded to receive the circular' piece (e) the under side of (e) and the upper partof the circular base have corresponding oblique sided grooves of suiiicient thickness to receive the ends of the pieces (f) and (g) outside of the cutting knives and which ends are made to correspond to the oblique sides of the grooves so that when the part (e) is forced down the oblique sides of the grooves acting upon the oblique ends of the parts and (g) force. them toward the axis of the head and they are so made to clamp the knives throughout their entire length firmly against the flattened sides of the main part, the upper end of which is screwed and furnished with two nuts (iz.) and (i). (it) is for the purpose of forcing down the part (e) as be- (z') is a set nut by means of fore described.
which (h.) is prevented from turning and getting loose.
A guard (J) is screwed to the upper end of (a) in such a manner that its height may be adjusted according to the height of the stuff to be worked. This guard projects outward beyond the edges of the knives, inclosing or covering that part of the head above the stuff to be worked and is for the double purpose of protecting the operators from mutilating their hands as by accident has frequently been done by contact with the cutters and of preventing the stuff from being thrown up or drawn up from the table by the cutters as it is otherwise apt to be under various circumstances. The exterior of (J) is made round and smooth exceptwhere the wrench is applied. The flange at (n) serves to keep the guard concentric with the axis of head. The nut (l) is to adjustand bind the guard (J This is done by turning the guard up or down upon the screw to near the desired position, then turning the nut against the guard and apply the wrench to the hexagonal part (m) of the guard the nut (Z) is made round and smooth like the guard so that it may not bruise the hands when they chance to come in contact with it while in motion. The guard (J) may be made some larger than the head so that differentknives may be used with each size of guard.
Vhat we claim as our invention and desire to secure by Letters Patent is as follows:
W'e claim the adjust-able revolving guard (J), as constructed and connected, adjustably to the cutter head, carried by, and having all its movements, to eifectually protect the operator from mutilation, and to hold down the material receiving shape, essentially in the manner fully set forth.
HENRY D. STOVER. JAMES-W- BICKNELL. Witnesses J. H. THOMPSON, AXEL DEARoRN.
