CIRCULAR CUTTER.
Specification of Letters Patent.
Patented Jan. 2,1912.
Application filed March 24, 1911. Serial N 0. 616,578.
To all whom it may concern:
Be it known that I, WILLIAM E. PEADEN, Jr., a citizen of the United States, residing at Corbett, in the county of Santa Rosa and State of Florida, have invented certain new and useful Improvements in Circular Cutters, of which the following is a specificatlon.
The present invention relates to improvements in circular cutters, and is especially designed for cuttingfriction disks, such as washers, gaskets, etc. of leather, rubber or similar material. The device or tool is also applicable for use as a scriber in marking circular lines or curves. The essential object oftheinvention is the provision of a tool for the above purpose which is simple in construction, comparatlvely cheap in first cost, durable, proficient 1n use,"and capable of facile manipulation in adjusting it for different operations, for lnstance, in cutting disks of different diameters.
The invent-ion consists substantially in the novel combinations and arrangements of parts as hereinafter described and claimed and as illustrated in the drawings.
In the accompanying drawings I have illustrated an exemplifying structure constructed according to the best mode I have so far devised for the practical application of the principles of the invention.
Figure 1 is a plan view of the complete device. Fig. 2 is an elevation view, one of the beams being shown in section, for convenience of illustration. Fig. 3 is a detail sectional view illustrating the means for securing the cutting blade to a beam. Fig. 4 is a detail perspective of portions of the cams.
The tool is adapted for manual use in connection with the common type of brace, a portion ofwhich is indicated in dotted lines at A, Fig. 2; or power may be applied and thetool actuated in connection with a drill press. I
' The tool is exceedingly simple in construction and comprises a shank B, a pair of duplicate beams'C, C, and a securing wedge key D. The shank is formedat its lower end with a' needle point E, andat its upper end with a squared portion F, the latter for engagement with the socket of the hand brace or power drill press. Each beam 0,
as are also the other elements of the instrument, is preferably made of tool steel, and the beams are formed with complementary mortises C C. Each beam is equipped with a pair of slides G having an integral leg G, the end of which is tempered as required and fashioned into a comparatively broad flat cutting purpose of cutting or scribing. A set screw I is provided for each slide for adjustably securing the knife in desired position, the screw securely clamping the parts together as clearly shown in Fig. 8. The beams C, C,
are disposed at right angles to each other,
and are seated in the diametrically arranged slots K an K of the shank, the lower face of the lower beam resting upon the lower wall L of the slot K. The upper wall M of the slot K is inclined upon a. line complementary with the wedge face N of the key D."
It will be noted that the knives may be adjusted to different distances from the center of the beam. Forinstance, in Fig. 2, considering only the knife at the left, the blade is set to cut a circular disk approximately six inches in diameter, with the point E as a center. If it is desired to cut a disk with an open center, the knife at the right in Fig. 2 is used in conjunction with the first mentioned knife. By the use of the two knives, a disk six inches in diameter, with an open center approximately three inches in diameter is cut. By the use of four knives as in Fig. 1, two open center dlsks may be cut, the outside diameter of the inner disk being the same as the inside diameter of the outer disk, and the inner disk also having an open center, leaving a third disk cut from the intermediate disk.
The tool is capable of many variations for diflerent uses, and as above described and illustrated in the drawings fulfils the purpose set forth as the object of my nvent on.
Having thus fully described my lnventlon, what I'claim as new and desire to secure by Letters Patent is 1.;Af tool as described comprising a slotted shanlg 'a pair of beams angular-1y disposed in the slotted shank and a wedge key for securing the parts together, and a series of slides adjustable on the beams each having a cutting edge.
, 2., A tool as described comprlsmg a shank having diametrically disposed slots, a beam blade or knife H, for the in each slot and adjustable means for securing the parts together, and slides on the beams, each having a set-screw and a cut ting edge.
3. A tool as described comprising a slot ted shank, a pair of beams formed with complementary mortises, angularly disposed in the slotted shank and a wedge key for securing the parts together, and a series of slides adjustable on the beams each having 10 WILLIAM E. PEADEN, J R. Witnesses:
