ROUTlNG-CUTTER.
SPECIFICATION forming part of Letters Patent No. 740,690, dated October 6, 1903.
i Application led February l1, 1903. Serial No. 142,877. (No model.)
T0 1f/ZZ whom, t muy concern:
Be it known that I, JULIAN L. PERKINS, a citizen of the United States, and a resident of West Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Routing-Cutter, yof which the following is a specification.
My invention relates to a routing-cutter, with the object in view of providing au economical cutter which may be sharpened from time to time until it is substantially all used.
A practical embodiment of my invention is represented in the accompanying drawings, in which- Y.
Figure l is a View of the cutter in side ele- Vation as it appears ready for use. Fig. 2 is a similar view showing the cutter in edge elevation. Fig. 3 is a transverse section in the plane of the line A A of Fig. 1. Figs. 4, 5, and 6 represent, respectively, the half-sections of the cutter-stock and the cutter proper. Fig. 7 represents a section of the nut for holding the sections of the cutter-stock in assembled adjustment. Fig. 8 represents a transverse section through the cutter proper, showing its position odset fromthe axis of its rotation both edgewise and sidewise. Fig. 9 is a similar view showing the cutter odset from the axis of its rotation edgewise only, and Fig. 10 representsthe cutter set coincident with the axis of its rotation.
The shank of the cutter is denoted by l and its cutting-point by 2. It is formed of a strip of metal half-round or segmental in cross-section, the preferred form being that shown in Figs. l to 8, inclusive, Where it is formed of a segment less than' a semicircle in order to admit of its being set off from its axis of rotation in each of two directions-viz., both edgewise and sideWise--as shown in Fig. 8.
This form is preferable, because it gives the necessary lead and clearance to make a rapid clean cut when the tool is swung bodily along during its swift rotary movement.
The cutter l 2 is held securely in a groove 3 in the section l of the cutter-stock, the said section e being preferably less than a semicircle in crosssection, as shown in Fig. 3, and the groove 3 odset from the axis of the holder, as clearly shown in Figs. 3 and 5. The other section of the cutter-stock is denoted by 5. These sections 4 and 5 when assembled face to face form a substantially cylindrical stock with a screw-threaded end 6 made slightly taper for the reception of the clamping-nut 7 In practice the cutter l 2 is made a trifle thicker than the depth ofthe groove 3, so that the section 5 will have a bearing on it rather than upon the section 4, which will cause the two sections to tightly hug the cutter when the nut is turned onto the slightly-tapered threaded end 6.
As fast as the point 20E the cutter becomes worn or 'cooled it may be removed for sharpening, and as it is ofV the same cross-section throughout its body portion it will always present the same cutting edgennder similar grindings and may be readilyadjusted within its stock until it has been ground away to merely a short piece just long enough to benipped by the end of the holder.
, A cutter thus formed may be made of the nest quality of .metal and tempered to a nicety throughout, whileits stock may be of some suitable cheaper material, tougher, and hence not so apt to break as the more highly tempered one-piece cutters now in use will do unless great care is used in getting the quality and temper perfect.
l. A routing-cutter comprising a strip of metal segmental in cross-section and a sectional cutter-stock, one of the sections being provided with a groove odset from the axis of the stock and means for holding the sectional stock in assembled adjustment with the cutter therein.
2. A'routing-cutter comprising a strip of metal segmental in cross-section, a sectional stock comprising a lesser and' a greater section, a groove in the lesser section offset from the' longitudinal central line of the face of said section for receiving the cutter proper and means for holding the sections in assembled adjustment With the cutter therein.
In testimony that I claim the foregoing as myinvention I have signed my name, in presence of two witnesses, this 31st day of January, 1903.
.JULIANl L. PERKINS.
