No. 824,962. Specification of Letters Patent. Patented July 3, 1906.
Application filed June '7, 1905. Serial No. 264,065.
To all whom it Wuty concern.-
Be it known that I, FRANK E. THOMES, a I
citizen of the United States of America, and a resident of Portland, county of Cumberland, State of Maine, have invented certain new and useful Improvements in Core-Box Cutters, of which the following is a specification.
My invention relates to a core-box cutter, and particularly to certain improvements in my machine as patented February 23, 1904, i No. 753,178.
' table is raised and lowered, and k is a handwheel for operating the same. These parts are all substantially as shown in my prior patent and need no further explanation. Means are provided by which the cutter-head arbor, when a small cutter is to be used, maybe supported on both sides of the cutter-head. For this purpose I form a bracket 0, Fig. 3, which comes up outside of and above the upper level of the main gear, and in the upper end of this bracket is journaled the outer end of the arbor e, on which is secured the cutter-head In the above-mentioned machine a gear f and adjacent thereto the pinion e. As here was secured to the end of a horizontal shaft, f said gear engaging a second gear which was above it and which was pivoted on a stud projecting out from a bracket extending upi ward from the journal-box of the main shaft. j Secured to the upper gear was a cutter-head of the machine.
My present invention relates, first, to pro- I viding a bearing on each side of the cutter head instead of pivoting it on a stud, as shown; second, in making the cutter-head, the two gears, and their connecting mechanism quickly and easily removable as a whole, whereby they may be easily shifted and, finally, in providing an adjustable pivoting-point adapted to pivot the block on acenter over the cutter-head, whereby a hemispherical or annular recess may be formed in the block. These features of construction I will now proceed to specifically describe.
My invention is illustrated by means of the accompanying drawings, which show a corecutting machine provided with my improvements.
In the drawings, Figure 1 is a vertical section parallel with the shaft, showing the working parts in elevation. Fig. 2 is a section on the line at 00 of Fig. 1. Fig. 3 is an enlarged longitudinal section through the cutter-head and connecting mechanism with portions in elevation. Figs. 4 and 5 are plan views of blocks, showing the form of channels cut by the use of my pivoting device. Fig. 6 is a section on the line as a: of Fig. 3, and Fig. 7 is a plan view.
Referring to Figs. 1 and 2, A represents the table; a, the standard which supports the table; a, the horizontal slot through which the cutter-head works; 5 the main shaft; 1), and b the journal-boxes of the main shaft, and g the main gear. Zr: is the screw by which the which worked up through a slot in the table I shown, the other end of the arbor e is pivoted on a conical stud d, which projects outi ward from the upper portion of the box in whichthe outer end of the shaft is journaled. t represents the cutter held in a transverse hole in the cutter-head by a setscrew f.
For the purpose of making the cutting mechanism readily removable for the purpose of changing cutters I provide an extensionbox C, in which is ournaled a short sleeve gi on the outer end of which the gear 9 is secured. The sleeve 9 is adapted to slip on over the end of the shaft, and clutch mechanism is provided to hold it in place on the shaft.
As here shown, projections b are formed on the shaft, and slots or recesses are formed in the inner end of the sleeve, which recesses interlock or engage the projections 12 in the well-known manner. To hold the sleeve in. place, a nut g is screwed on its inner end over the recesses, this nut being contained in a re cess in the extension-box (J. The extensionbox is held in place by means of a rearward extension 0, which fits on top of the journalbox I) and is secured in place by a screw 0 I have represented in Fig. 2 the cross-section of a block in process of-being channeled, and in connection with such channels I may form annular or hemispherical recesses. For this purpose means are provided for pivoting the block 0 at a point on top and over the cutterhead. For this purpose I provide a horizontal adjustable arm i, held in a socket 77, secured to the clamp h, provided with a clamping-nut h. The end of the arm 2' is turned downward, and a pin 71 extends .down through, forming a pivoting-point adapted to enter the top of the block. In practice a small hole is bored to admit the pin. The pin 1' may be located directly over the center of the cutter-head when a hemispherical re cess is to be formed, or it may be located away from the head when a U-shaped channel is to be out, as shown in Fig. 4.
In Fig. 4 I show the under side of a block in which has been cut a U-shaped recess by the use of my improved machine. In this operation the block is run over the cutter, forming the half-round channels 1 in the usual way, to the dotted line p 19 a hole having been formed in the upper surface of the block opposite the point p. Into this hole the pin 1' is introduced and the arm i clamped in place. The block 0 is now swung around. one hundred and eighty degrees and is then run straight, forming the other channel 1", parallel with the channel 1. When a channel is to be terminated, as shown in Fig. 5, by a spherical end, the cutter is run straight to the point p in the center of the channel, and the pin i is inserted in the top of the block opposite this point. The block is then swung around one hundred and eighty degrees, as before, and the special end thus cut.
The operation of my machine and the use of the above-described improvements will be readily understood. The cutter-head projects up through a slot in the table and is provided with mechanism here shown, by which it may be raised and lowered vertically. The block to be cut is run over the cutter-head parallel with its axis, cutting first a shallow channel, which is gradually deepened by raising the cutterhead until the channel' be comes semicylindrical in form. When small cutter heads are to be used, the outside bracket 0 furnishes a support for the outer end of the arbor, and there is sufficient space between the body of the bracket and the gear to allow the cutter to revolve.
By constructing the cutter-head and gears, as shown, mounted in the extension-box the whole can be quickly changed to substitute one cutter for another. The pivoting-arm enables me to out either hemispherical or annular channels quickly and easily.
I claim- 1. In a core-box cutter, the combination of a journal-box, a main shaft j ournaled therein, a gear on the end of said shaft, a bracket on the end of said box extending above and outside of said gear, an arbor one end of which is j ournaled in the upper portion of said bracket and one end in the upper portion of said box, a pinion on said arbor engaging said gear, a cutter-head adjacent to said pinion, a cutter in said cutter-head being adapted to rotate in the space between said bracket and said gear.
2. In a core-box cutter, the combination of a journal-box, a main shaft journaled therein, a gear on the end of said shaft, a bracket on the end of said box extending above and outside of said gear, an arbor, one end of which is journaled in the upper portion of said bracket, a stud on said box on which the other end of said arbor is pivoted, a pinion on said arbor engaging said gear, a cutter-head adjacent to said pinion and a cutter in said cutter-head adapted to rotate in the space between said bracket and gear.
3. In a core-box cutter, the combination of a journal-box proper, a shaft journaled therein, an extension-box having a rearward projection adapted to be secured to said box, a sleeve ournaled in said extension and adapted to receive the end of said shaft, a clutch mechanism for locking the sleeve to the shaft, a gear on the outer end of said sleeve, a pinion pivoted above said gear and engaging with it and a cutter-head secured to the journal of said pinion.
4. In a core-box cutter the combination of a journal-box, proper, ashaft journaled therein, an extension-box having a rearward projection adapted to be secured to said box, a sleeve journaled in said extension-box and adapted to receive the end of said shaft, projections being formed on said shaft and notches in the rear end of said sleeve to engage said projections to form a clutch con nection, a nut adapted to screw on the rear end of said sleeve over said notches, a gear on the outer end of said sleeve, a pinion engaging said gear and a cutter-head connected with said pinion.
5. In a core-box cutter the combination of a main shaft, a gear on the end of said shaft,
a pinion above said gear and engaging therewith, a cutter-head connected with said pinion, and a horizontally-adjustable arm having a downward projecting end provided with a pivoting-point adapted to enter the wood block and to form a center over the said cutter-head to form a hemispherical or annular or other like recess.
