GEORGE J. SHIMER AND SAMUEL J. SHIMER, OF MILTON, PENNSYLVANIA.
CUTTER-HEAD.
SPECIFICATION forming part of Letters Patent No. 241,432, dated May 10, 1881.
Application fnen Mnl-@11 1o, 1881. (trader.)
,To all whom it may concern.-
Bc it known that we, GEORGE J. SHIMER and SAMUEL J. SHIMEE, citizens of the United States, residing vat Milton, in the county of Northumberland and State, ot' Pennsylvania,
. have invented certain new and useful Improvements in Gutter-Heads; and we do hereby declare 'the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit ap-` pertains to make and use the same, reference being had to the accompanying drawings ,`and to letters or iigures of reference marked thereon, which form a part ot' this specification.
Our invention relates to cutter-heads that are used on matching and molding machines for matching, grooving, and iinishing the edges of lumber, and particularly to that class wherein bits or cutters are employed to produce a,
divided cnt and to operate with clearance at the side of each cuttingedge. A
Ourinvcntion also relates to the peculiar construction ot' the bits or cutters, operating g in pairs, so as to overlap each other on the inner lineof cut, and capable of lateral adjust 4 ment for matching and molding lumber.
Our invention consists in a cntter-headcomposed of two sections or pai ts, operating conjointly and capable of lateral adjustment, in combination with bits or cutters having the outline of a certain mold formed on their outer surfaces at an angle with the edges upon which they are secured totheir respective sections.
Our invention further consists, in combination with the cutter-head composed ot' two sections or parts, of an elastic cushion operating against the movable section.
Our invention further consists, in combination with the cutter-head composed ot' t-wo sections or parts, of an elastic cushion or coiled spring and an adjusting means, whereby'the overlapping edges of the cutters of the sections can be increased or decreased.
Our invention further consists in the peculiar construction of the bitor cutter, as will be hereinafter described and claimed.
Our invention further consists in the novel construction and combination of parts, as will be hereinafter described and specifically claimed.
Figure l of the drawings is a perspective View ofourimproved tool. view ot the saine. of the stationary with its bits or cutters, and showing fully a coiled spring surrounding the hub. Fig. 4 is a perspective view ofthe adjustable section of the cutter-head with its bits or cutters. Fig. 5 is a vertical sectional view, showing the relative position of all the parts. Fig. 6 isa perspective view ofthe bit or cutter. edge vien' ot' one of the bits, showingthe mode ot' operation upon a piece of lumber.
In the annexed drawings,forming a part of this specification, the letter A represents the cuttenhead, composed ot' two sections or parts, B and C. The section B (see Fig. 3) is constructed with a central hub, D, having at its upper end anexterior screw-threaded portion, a, and at its base with re-ent'orced side ianges or segments, E E,directlyopposite each other, and arranged in planes at right angles to the axis of rotation. The section G (see Fig. 4) is constructed with a central sleeve, F, theinterior diameter of which is a littie greater than the exterior diameter ofthe hub D ot section B, so as to pass over the same easily, and to permit ot' vertical adjustment, and is also constructed with the re-ent'orced side iianges or segments, E2 E2, which are arranged directly opposite each other, as seen in the drawings. The side flanges of the respective sections are formed with mortises b, to receive the bits or cutters, and provided with set-screws C at or near one end, on the upper surface, to secure the bits or cutters to their seats. rlhe mortises in the respective sections are parallel to each other, in order that the cutters arranged therein shall move in the same plane. These sections are made of cast metal with the openings and passages cored, and should be ofsufi- Fig. 2 is a bottom Fig. 3 is a perspective view cient strength to resist the torsional strain upon the bits when the tool is in operation.
Arranged around the hub D of the section B (see Figs. 3 and 5) is a coiled spring, Hhor its equivalent, having a tension ot sufficient strength to act as a nut-lock. This coiled spring rests upon the floor of the lower section, and the upper end bears upon the upper section when adjusted in position, as seen in Fig. 5 of the drawings. The office of this spring coiled around the hub is to automatisection of the cutter-head Fig. 7 is an IOO cally adjust the upper section upwardly or outwardly and retain the same in the adjusted position. The downward adjustment of the upper section is accomplished by the adjusting-nut d engaging with the screw-th reads on the upper end of the hub.
The letter I (see Fig. 6) represents a bit or cutter with two cutting-edges,1and 2,in transverse section, having the shape or outline to out a certain mold which is formed on the outer surface by planing or milling. ln this example of a bit for forming a groove the proj eetin g cutting-edge 2 is arranged at an angle to the basev of the bit, or when it is secured to the head. These cutters are introduced into the mortises and properly adjusted in pairs or series," so as to partially overlap each other on the inner line of the cut.
It will be understood that as the cutters wear away they will make the groove narrower and tongue wider; but to maintain the uniformity of the groove and tongue the upper section, with its cutters, is adjusted so that they will overlap each other on the inner' line ot' cut.
The modus operandi of these overlapping bits, for alternating the cut and dividing the chip upon the inner line of cut, is fully eX- plained in the reissued patent of G. J. Shimer, dated February 12, 1880, and in our patent dated January 11, 1881. i
The parts constituting the tool are put together in the .following manner: 0n the hub ot' the lower section is arranged the coiled spring, after which the movable upper section is passed over the hub ot' the lower section, at right angles thereto, until it rests upon the upper end of the coiled spring, when the nut is applied and adjusted to form or constitute the interlocking ofthe sections, as seen in Fig. 1 of the drawings. The bits are properly adjusted in pairs in the mortises, and secured in their seats by means of the set-screws, and the desired overlap adjustment of the bits or cutters is accomplished by screwing the nut by means of a suitable wrench down upon the upper section, which will give the nice desired adjustment. The bits are sharpened and the cutting-edges adjusted to a common circle in the well-known manner.
It is obvious that as these bits or cutters are worn off by use and repeated sharpening, their lateral adjustment must equal the inclination given for clearance to their leading points, and that, owing to the construction seen in Fig. G, the bits operate with side clearance to their leading points when they are adjusted to the work in the ordinary manner.
In lieu of the coiled spring a rubber buffer or cushion may surround the hub, or a number of spiral or flat springs incased between the sections.
We do not wish to corinne ourselves to the precise construction herein described and shown, as slight changes may be made without departing from the spirit of the invention.
Vhat we claim as our invention, and desire to secure by Letters Patent, is-
1. A cuttter-head composed ot' two parts operating conjointly and capable ot' lateral adjustment, the solid bits or cutters ot which have the outline ot' a given shape formed on their outer surfaces atan angle with the edges upon which they are secured to their respective sections, substantially as described, and for the purpose set forth.
2. In a cutter-head, the combination, with the two sections composing the head, ot' an elastic cushion operating upon the movable or adjustable section, substantially as and for the purpose set forth.
I5. In a cutter-head, the combination, with the two sections composing the head, otl an interposed elastic cushion and an adjustingl means, substantially as and for the purpose set forth'.
4. A bit or cutter for a cutter-head having two cutting-edges in transverse section, the cutting-edge that shapes or forms the mold being formed on a projection on the face or" the bit or cutter, at an angle to the base thereof, substantially as described.
5. The improved cutter-head hereinbefore described, consisting of the section B, movable section C, with their bits, the coiled spring H,
` and adjusting-nut, substantially as described.
ln testimony whereof we affix our signatures in presence ot two witnesses.
