TIMOTHY F. TAFT, OF YVORCESTER, MASSACHUSETTS.
DEVICE FOR OPERATING CUT\TERHEADS 0F ]?1'..Al\TI1\TGr-MACBIINIl-JS.`
Speccation of Letters Patent No. 11,017, dated June 6, 1854.'
T0 all whom t may concern Be it known that I, T. F. TAFT, of forcester, in'the county of Worcester and State of Massachusetts, have made certain new and useful improvements in the method of hanging and arranging the cutters o-f planing-machines, which improvements, though particularly adapted to the machine known as Daniellss planing machines, may be advantageously applied to those of other construction; and Ihereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification.
In the Daniells planer as heretofore constructed it has been necessary to place the cutter at a considerable distance from the center of motion to accommodate it to the planing of wide stuff. There is a limit to the length which can be advantageously given to these cutters and it is obvious that the length of plank which can be operated upon at each revolution of the cutter head is 4dependent upon the length of the cutter, which also limits the velocity with which the plank can be fed through the machine. On this account machines of this character are capable of working much less rapidly than those in which stationary or cylinder cutters are used; but as these latter machines are incapable of planing out of wind the Daniells planer is extensively used for all joiners and panneled work. Various attempts have been made to enable a more rapid feed to be given to this machine.
To effect this end is one object of my present invention.
The shaft of the cutter head in the Daniells planer requires to be set at an inclination from the vertical in order that the finished board may not be scratched by the return of the plane iron and in consequence of this inclination the surface of the board is planed `slightly hollowing.
My invention has also `for its object the remedying of this evil, by which means my machine is enabled to perform more perfect as well as more rapid work.
My invention consists in placing my cutyter head upon the end of a horizontal arm,
which is caused to vibrate across the surface of the board, `by which means I am enabled to place my cuttersvery near to their center of motion and to give to the machine a much more rapid feed, the hollowing of the surface of the board before spoken of being entirely avoided.
To enable others skilled in the art to make and use my invention I will proceed to describe the manner which I have adopted of carrying it out, referring generally to the well known parts of the machine and then describing more minutely the improvements which I have added thereto.
In the accompanying drawings .Figure l is a perspective view of a Daniells planing machine with my improvement attached.
Fig. 2 is an end view, and Fig. 3 a plan of the vibrating arm and cutter head.
A is the framework of the machine.
B is the bed upon which the material'is carried through the machine in the customary manner.
Motion is communicated to the operating parts of the machine through a band from a prime mover which passes around the pulley C upon the shaft D.
E is a shaft which is driven by the band T, which passes around the pulley U and also around a small pulley upon the shaft D. The shaft E carries the eccentric F, the object of which will be explained hereafter.
G is the gate which carries the cutting mechanism and which is made to rise and fall in the customary manner by means of the screw l/V.
H is a shaft which is caused to revolve by the band I from a large pulley upon the shaft D (not seen in the drawings) which passes around the drum K.
L is a horizontal arm pivoted to the bottom of the shaft H, but not attached thereto. The rear of this arm is connected by means 0f the rod M to the eccentric F, andthus as the latter revolves the arm is caused to vibrate transversely across the machine.
N is a standard upon the end of the arm L, which carries the cutter shaft O, on the bottom of which is secured the cutter head P. This cutter head is caused to revolve by the band Q, which receives motion from the pulley R upon the shaft H. From these connections it appears that as the shafts H and E revolve the cutter head is caused to revolve and the arm L to vibrate horizontally. The shaft O with the cutter head being light may be caused to revolve with great rapidity, and on account of the small diameter of the latter cutters of a much greater length may be used than can be operated upon an ordinary Daniells machine.
It Will; be seenv that each tirne the cutter chine being not unlike those of theA machines head vbrates across the surface Ofthe'board in either direction a length Of board may be dressed equal tO One-half the'length of the cutter and that the board Will be dressed in a horizontal plane and not hOllOWing, as in the machines of the usual construction.
S are rollers Which are caused tO bear upon the surface of the plank and retain it 10 upon the bed.
The other parts and Operations Of the rnanOW in use need not be further described.
What I claim as my invention and desire tO secure by Letters Patent is- Hanging the planing cutters tO the vibrating/ arrn L Or its equivalent in the manner and for the purpose set forth.
