SPECIFICATION forming part of Letters Patent No. 777,250, dated December 13, 1904.
Application filed duly 2, 1903. Serial N0. 164,035. (No model.)
To all 71171/0711, '1115 711/041/ con/cern:
Be it known that I, Ti-IouAs EYNON, a citizen of the United States, residing at Chicago, 1n
the county of Cook and State of Illinois, have invented certain new and useful Improvements in Milling-Cutters; and I 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 which itappertains to make and use the same.
This invention relates to improvements in millingcutters, and particularly to novel means for retaining' the cutter-teeth in operative position.
The object in view is the provision of means for clamping milling-teeth in the periphery of a disk or milling-head, while leaving the periphery of suchl disk or head integral eX- eept for the teeth-receiving notches.
With this and further objects in view the invention consists in certain novel constructions, combination, and arrangement of parts, as will be hereinafter fully described and claimed.
In the accompanying drawings, Figure 1 represents aview in end elevation of a millinghead embodying the features of the present in vention. Fig. 2 represents a view in side elevation of the same. Fig'. 3 representsa frag'mentary end elevation of a slightly-modified form of the same. Fig. 4 represents a view in side elevation of the structure disclosed in Fig. 3. Figs. 5 and 6 represent views similar to Figs. 3 and 4., respectively, of a further modification.
In the present invention I contemplate clamping milling-teeth in position, and the means employed for effecting' the clamping action may be applied to any suitable disk, as disclosed in Figs. 3 and 4., which may be afterward keyed to a rotating shaft, or the disks may be secured by the present improvement directly to a milling-head, as disclosed in Figs. 1 and 2, which latter disclosure is my preferred construction.
Referring to the drawings by numerals, I indicates any suitable milling-head formed with a central passage 2 and designed te receive any suitable rotating spindle. The
outer edge of the head l formed with a series of spaced notches 3 3 of a width to snugly receive milling-teeth 4., which milling-teeth are preferably made in the form of solid disks having beveled peripheries forming cutting' edges. The notches 3 divide the milling-head into a series of segments, each alternate one of which is formed with a transverse aperture 6, designed to receive an expanding-plug 7. The apertures 6 are formed in the material spaced from the edge of the milling-head, so as to leave the said edge continuous and integral except for the notches 3.
In operation the disk teeth 4 are positioned within the notches 3 and the plugs 7 are driven home within the apertures 6, whereby the molecules composing the material between the respective apertures 6 and the next contiguous notches 3 will be moved laterally for reducing the width of the said notches 3 and tightly clamping the teeth 4. in position. The fact that the edge of the milling-head is left continuous and integral adds materially toits strength and duiability,\vliile the clamping' action effected through the use of the wedgeplugs 6 is attained as eflieiently as may be desired. After the teeth i have been clamped in position the head l `is mounted upon a rotating spindle and employed in its milling' operation until the cutting edges of the respective disk teeth I have become dull, whereupon the plugs 7 are removed and the said teeth are released and rotated for a slight distance for presenting' a new cutting-surface, and the plugs 7 are then released for clamping such teeth in position.
It will be observed that by the arrangement specified one plug is designed to clamp two teeth, the segment of the milling-head between a set of teeth eiiected by a given plug and the next contiguous set being leftin an unbroken or integral condition.
In Figs. 3 and I I have illustrated a disk 1 provided with notches for receiving' cutterteeth 4 and apertures 6 similar in all respects to the structure just described except that a disk is employed instead of a cutter-head, said disk being designed to be mounted upon a spindle in any suitable and desired manner. The apertures are positioned transversely of the disk instead of radially, as are the aper- IOO tures 6 as described with reference to the structure disclosed in Figs. l and 2.
Figs. 5 and 6 disclose a further modification, which corresponds exactly with thestructure disclosed in Figs. 3 and 4 except that cutterteeth 4 are mounted within notches formed in a disk l, which teeth are rectangular in form and designed for use for cutting or cleaning out square corners.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A milling device comprising a body formed with a plurality of peripheral millingteeth receiving notches, and apertures formed in the body between alternate notches and spaced therefrom whereby milling-teeth introduced into said notches may be locked therein by the introduction of wedgesinto said apertures, the periphery of said body being left continuous and integral except for said notches.
2. A milling device comprising a body formed with a plurality of peripheral notches, apertures being formed transversely through said body between said notches, milling-teeth within said notches, and wedges driven into said apertures, whereby said teeth are wedged in position by expansion of the material of said body, the said body, except for said notches and apertures, being left integral.
8. A milling device comprising a body formed with a plurality of peripheral millingteeth receiving notches and apertures formed in the body between some of said notches and spaced therefrom, whereby milling-teeth introduced into said notches may be locked therein by the introduction of wedges into said apertures, said body, except for said notches and apertures, being left integral.
vIn testimony whereof l hereunto affix my signature in presence of two witnesses.
