JOHN F. OADELL, OF BALTIMORE, MARYLAND, ASSIGNOR TO OTT. MERGENTHALER COMPANY, OF BALTIMORE, MARYLAND, A CORPORATION OF DELAWARE. J
SPECIFICATION forming part of Letters Patent No. 700,736, dated May 27, 1902.
Application filed May 15,1901. Serial No. 60,277. (No model.)
To all whom it may concern:
Be it known that I, JOHN F. OADELL, a citizen of the United States, residing at the city of Baltimore, in the State of Maryland, have invented certain newand useful Improvements in Milling-Machine Cutters, of which the following is a specification.
This invention relates to improvements in milling-cutters by which the cutting-blades may be adjusted for making cuts of various widths and may be locked securely in any adjustment.
In the accompanying drawings, Figure 1 is a central longitudinal section through a milling cutter embodying my improvements.
Fig. 2 is an end View of' the same, partlybroken away. Fig. 3 is a side View of a portion of the cutter, the cutter-blades thereon being parallel with one another. detail View showing the arrangement of an adjusting-screw and cutter-blade. Fig. 5 is a side view of a cutter, showing the cutterblades arranged in angular relation to one another. Fig. 6 is a similar View showing the cutter-blades arranged parallel with one another, but inclined withreterenceto the body. Fig. 7 is a perspective View of one of the cutter-blades.
Referring to Figs. 1, 2, 3, 4, and 7 of the drawings, 1 indicates the cylindrical body of the cutter, which may be hollow, as shown, or solid and which is provided with a series of channels 2, extending longitudinally along its outer surface. Within these channels are arranged the cutting-bladesfi, each having a base 3", which extends forwardly of the cutting edge 3, and the upper edge of said forward projection is'beveled, as shown at 4. These blades are normally locked within the channels by means of locking-screws 5, having tapered portions 6, which bear against the beveled facesof the blades, and cylindrical portions 7, bearing against faces 8 in the body-piece, which are parallel with the axes of the screws. This arrangement of the locking-screws is substantially the same as that shown in my Patent No. 598,904, granted February 15, 1898. In that patent, however,
which was for a reamer, the blades were not Fig. 4 is a longitudinally adjustable and were provided with tapering recesses upon their inner faces adapted to receive the tapering portions of the locking-screws,whereas in the present invention the blades are provided with plain beveled faces 4, so that the screws may engage and lock the-blades in any longitudinal adjustment. The blades of the cutter are all of the samelength, and each blade is provided with a transverse groove 9 in its rear side near one end. Adjacent to and in the rear of each cutter is an adjusting-screw 10, fitting within a threaded opening 11 in the end of the bodypiece parallel with the blade. This screwis provided with a head or flange 12, which engages the groove in the end of the blade, so that the turning of the screw adjusts the blade longitudinally of the bodypiece when the former is not locked in position bythe locking-screws. As shown, the adj usting-screws for the series of blades are arranged alternately at opposite ends of the body-piece, and" the consecutive blades are grooved transverselyat alternately opposite ends. By this arrangement it will be seen thatthe blades are independently adjustable longitudinally of the body-piece and that the alternate blades may be movedin opposite directions to increase or decrease the width of the cut. In adjusting the blades the locking-screws are of course first loosened, and the adj usting-screws at one or both ends of the body are turned to move the blades into the desired position. The locking-screws are then tightened, their tapering faces fitting against the beveled faces of the blades and clamping the latter. The openings for the adjusting-screws are preferably-counterbored, as shown at 11, Fig. 4, in order that the heads 12 may enter the recesses thus formed and draw the ends of the blades in flush with the ends of the body.
While for smooth working it is desirable that the consecutive blades should be'adj ustable in alternately opposite directions, it will be understood that the cutter would be operative if the blades were arranged insimilarly adjustable groups of two or three or the alternate blades or groups only need be adj ust= ed, the remaining blades being permanently locked in position. The arrangement of the adjusting-screws in the rear of the cutterblades is a feature of some importance, as in this position they are out of the Way and not apt to be clogged with metal cuttings. By these improvements a very simple means of varying the effective length of the cutter is provided.
The cutter-blades may be arranged upon the body in various ways. In Figs. and 6, for instance, the grooves 2 and the blades 3 are inclined with reference to the body. In
the former figure the consecutive grooves and blades are inclined in alternately opposite directions, while in Fig. 6 they are inclined in the same direction.
It will be understood that for the purpose of increasing the diameter of the cutter or providing for wear the blades may be underlaid with suitable metal strips arranged within the channels.
Having thus described my invention, what -I claim, and desire to secure by Letters Patadjustable cutting-blades within said chan-- nels and having their cutting edges extending I outwardly beyond the periphery of the bodypiece, each blade having a base projecting forwardly from the blade, said base having a plain beveled surface on its forward side, and locking-screws extending into the body and having tapering portions adapted to engage the beveled surfaces of the blades.
3. In a milling-cutter, the combination of a body-piece having a series of longitudinal channels on its outer surface, longitudinallyadjustable cutting-blades in said channels, and adjusting-screws extending longitudinally into the body-piece adjacent to the blades, said screws and blades being connected to mutually engage, whereby the blades may be adjusted in either direction by turning the screws.
4. In a milling-cutter, the combination of a body-piece having a series of longitudinal channels on its outer surface, longitudinallyadjustable cutting-blades in said channels,
each blade havinga transverse groove on its rear side near one end, and adj usting-screws extending longitudinally into the body in the rear of the blades, each screw having a flange engaging the slot in an adjacent blade.
' 5. In a milling-cutter, the combination of a body-piece havinga series of channels on its outer surface, cutting-blades in said channels, each having a plain beveled surface on one side and a transverse groove near one end, adjusting screws extending longitudinally into the opposite ends of the-body adjacent to the blades, each adjusting-screw having a head engaging the groove in the adjacent blade, and locking-screws having tapering heads adapted to engage the beveled surfaces of the blades.
6. In a milling-cutter, the combination of a body-piece having a series of longitudinal channels on its outer surface, adjustable cutting-blades within said channels, each blade having a plain beveled surface on one side and a transverse groove near one end, adjustingscrews extending longitudinally into the body adjacent to the blades, each adjusting-screw having a flange engaging the groove in the adjacent blade, and locking-screws having tapered headsadapted to engage the beveled surface of the blades.
7-. In a milling-cutter, the combination of a body-piece having a series of longitudinal channels on its outer surface, cutting-blades in said channels, each blade having a transverse groove near one end, the consecutive blades having their grooved ends at opposite ends of the body-piece, and adjusting-screws extending longitudinally into the body-piece adjacent to the blades, each screw having a flange engaging the transverse groove in the adjacent blade.
8. In a milling-cutter, the combination of a body-piece having a series of longitudinal channels on its outer surface, cutter-blades in said channels, each blade having a plain beveled surface on one side and having a transverse groove near one end,.and the consecutive blades having their grooved ends lying at opposite ends of the body, adjusting-screws extending longitudinally into the body adj acent to the blades each screw having a flange engaging the groove in the adjacent blade, and locking-screws having tapering heads adapted to engage the beveled surfaces. on the blade.
9. A longitudinally-adj ustable milling-cutter blade having a transverse groove or recess near one end and a base projecting for- Wardly from the blade, said base having a continuous beveled face 4 on its forward side, substantially as described.
In testimony whereof I affix my signature 7 in presence of two witnesses.
