JEFFERSON KINDLEBERGER AND wiLLIAM'AUGUsTUs ARNOLD, Or- SAN` FRANCISCO, CALIFORNIA, ASSIGNORS 'ro THE INVENTORS ASSOCIATION, Or SAN FRANOISOO,
OALIFORNrA.
Letters Patent N o. 95,809, dated-ctober 12, ISGS.
IMPROVEMENT IN CUTTER-HEAD.
The Schedule referred to in these Letters Patent and making part of the same.
Be it known that we, JEFFERSON KINDLEBERGER and WILLIAM AUGUSTUS ARNOLD, of the city and county of San Francisco, State of California, have invented an Improved Gutter-Head for planers; and we do hereby declare the following description and accompanying drawings are suicient to enable any person skilled in the ait or science to which it most nearly appertains, to make and use our said invention Orimprovement without further invention or experiment.
Our invention relates to an improved cylinder or cutter-head for wood-plauing-machines; and
It consists 'in a novel and improved method or arrangement for securing the cutting-bits in the planerhead, so that they may be permanently fixed, when desii-ed, and readily adjusted when necessary.
In order to more fully illustrate and explain ourinventon, reference is had to the accompanying draw-l ings, forming a part of this specification, in Which- Figure 1 is an end view of the planer-head.
-Figure 2 is a side view, with the cutters in place.
- Figure 3 is a side view, with the cutters removed.
A is the cylinder or planer-head, which carries the bits or cutters B.
The cutter-head is made, as shown at iig.. 3, having the longitudinal slots H passing thro igh it, "opposite to each other, and on both sides ofthe centre.
vlliese slots or chambers are so made that the sides toward or nearest the centre are made on an incline in one direction, while the sides forming the planes of, the segment J, or opposite sides, are straight.
A shoulder, I, is formed by aprojectng flange near the side of the opening or slot through which the rear end of the bit passes, narrowing the slot, until it is just large enough to partially close the opening, and" leave space for the bit to pass through.
A screw, F, having a square-cut thread, is secured to one end ofthe planer-head, by means of a'shoplder, a, on the inside of the slot H and a nut, B', and on the outside or end of the planer-head, thus xing the screw to its place, but allowing it to turn freely through the partition between the slot and end of the cylinder, and forming a set-screw.
- This screw is so arranged that it lies partly embedded in the metal of the cylinder on the under side, or side nearest the centre, in a recess or channel prem pared to receive it, thus leaving only the upper half of its circumference projecting upward.
The planer-bits or cutters B are made of the exact length and width required to fit-into the slots resting against their upper sides, the bits or cutting-points projecting through the narrow portions of the slots in the cylinder.
Underneath the cutters B are two metal plates, c and E.
The plate c isv made tapering on one side, so as to -form a wedge, and has on lits under side a semicircular female screw, f.
This plate rests upon the inclined bottom of the slots H, in such a manner that the upper or projecting half of the screw E will operate in the semicircular female screw in the plate.
The other plate, E, is placed between the plate c and cutter B, and is held in place by'a sorew,'h, which passes through a slot in the plate, and is firmly screwed into the'wed e-shaped plate c. thus holding them together, but a lowing either to be moved a certain distance from side to side.
In securing the cutters in the slots, the two plates c and E are iirst inserted into the slot, and placed so that the female screw j' shall rest upon the set-screw F; the cutter is then introduced above these two plates, and set with its bit or cutting-edge projecting to the required distance from the cylinder; the set-screw F is then turned, drawing the wedge-shaped plate c toward the narrow end of the slot H, thus binding the cutter rmly to its place.
By this means the cutters can be readily and firmly xed to their proper places, and, whendesired, can be adjusted in any manner required, by simply loosening the plates c and E, by turning the screw F.
The usual nuts which project from the circumference ofthe cylinder are done away with, thus allowing the bits to be set as short as desired.
Having thus described our invention, l j
What we claim, and dsire to secure by Letters Patent, is-
The cylinder A, provided with wedge-shaped slots, H H, in combination with the plates E E and wedgeshaped plates cc, constructed and arranged to operateY substantially as described.
In witness whereof, we have hereunto set our hands and seals.
