IMPROVEMENT IN PLANlNc-MACHINES.
Specification forming part of Letters Patent No. 161,995, dated April 13, 1875; application filed February 23, 1875.
To all whom it may concern:
Be it known that I, DANIEL L. TOPPAN, of Somerville, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Planing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part ot' this specilication, in which- Figure l is a perspective view, representing 'my improvement applied to a planing-machine. Fig. 2 is a longitudinal section through the center of the cutter-shaft and its bearings. Fig. 3, detail in perspective.
In planing knotty and cross-grained lumber in machines ot' the present construction, the knots are often broken and thrown out, and the fibers oi' the cross-grained portions are displaced, thus leaving the surface rough and uneven.
To overcome these difculties is the object of Inyinvcntion, which consists in imparting to the cutter-shaft a simultaneous lateral and rotary motion, whereby the knives are caused to revolve in constantly changing vertical planes, thus producing a shearing cut, the effect of which is to prevent the knots from being removed, and to give the cross-grained portions a smooth and even surface.
To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.
In the said drawings, A represents the bed of a planing-machine, and B the cutter-shaft, which revolves in bearings c b, and is pro;
vided at one end with a pulley, C, over which passes a belt, D, by which it is revolved. Within the two portions of the bearing a is formed a continuous cam-groove, c, into which tits a friction-roll, d, on a stud, e, projecting out at right angles from the cutter-shaft B, by which construction, as the latter is revolved, it simultaneously receives a lateral motion, causing the cutters h secured thereto to move transversely across the surface of the board being planed, a shearing or drawing cut being thus produced, which reduces the knots and cross-grained portions ot the lumber, and leaves a smooth and even surface, as desired, which cannot be accomplished where the cutters revolve in the same vertical plane, as heretofore.
Instead of a cam-groove within the bearin g a, for the reception of a stud or pin on the cutter-shaft, the latter may be provided with a cam-groove for the reception of a stationary pin or projection; or the cutter-shaft may receive its lateral motion by means of any with cani-grooves c c, and bearing b, substan- Y tially as described.
Witness my hand this 18th day of February, A. D. 1875.
DANIEL L. TOPPAN. Witnesses:
