IMPROVEMENT IN CUTTER-HEADS.
Specification forming part of Letters Patent No. 181,230, dated August 15, 1876, application filed September 9, 1875.
To all whom it may concern Be it known that I, J OHN H. WHITAKER, of Davenport, in the county of Scott and State of Iowa, have invented an Improvement in Gutter-Heads, of which the following is a specification:
My invention consists in the combination of a cutter-head with a series of circular knives fastened to the head eccentrically, the whole to be attached to a machine for pointing fencepickets. I
In the annexed drawing, Figure 1 represents a side view of the cutter-head with the knives fastened to it; Fig. 2, an end view of the cutter-head, showing the mode of fastening the cutters eccentrically to the center of rotation; Fig. 3, an illustration of the way of applying these cutters to the revolving arhors of a machine for cutting the points to pickets.
H represents a cast-iron cutter-head with a hole, a, through its center, through which passes a revolving shaft. The two outer surfaces b 0 and d 6 form arcs of circles, the cen-' from one-eighth of an inch to three-sixteenths I of an inch.
The knives k and k have the same centers for their curvature as the respective surfaces b c and d 0, upon which they are fastened by means of iron screws. sections of these two knives k and 7c are of exactly the same shape as the points required to be cut on the wooden pickets.
In Fig. 1 is shown the cutting-edge i i i t of the knife, so as to make the edge cut on a bevel over the whole surface, and thus give the necessary draw to the cut, in order to prevent cross-grained wood from splitting. By means of the small eccentricities 0 0c and'o y, any required grinding or sharpening of the knives k and It will not alter perceptibly the form of the out.
In Fig. 3 I have represented, in a crude manner, the mode of applying these cutters. F F is intended forthe frame of a tenonmachine. 8 and q are two revolving shafts on the outer ends of which are fastened the two cutters c and 0. T is a sliding table upon which rest the pickets P to be pointed.
What I claim as my invention, and desire to secure by Letters Patent, is
The cutter-head H, with its eccentric surfaces I) c and d e, in combination with the circular knives 7a 7a, and the bevel cutting-edge t i, substantially as and for the purpose set forth.
JOHN H. WHITAKER.
