SETTING-GAGE FOR CUTTERS.

SPECIFICATION forming part of Letters Patent No. 620,760, dated March '7, 1899.

Application filed December 23, 1898. Serial No. 700,160. (No model.)

To aZZ whom, it may concern:

Be it known that I, SAMUEL S. FARNEY, a citizen of the United States, residing at Castorland, in the county of Lewis and State of New York, have invented certain new and useful Improvements in Devices for Adjusting the Knives of Cutter-Heads; and I do 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 it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in devices for use in holding the cutter-heads of matching and planing machines; and it relates more particularly to the provision of a simple and efficient device of this character which is especially adapted for use in holding and adjusting the cutterheads of matching-machines and for adjusting the knives of said cutter-heads.

To this end and to such others as the invention may pertain, the same consists in the peculiar construction of the device and in the combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a side elevation of my invention. Fig. 2 is an end view of the same. Fig. 3 is an enlarged detail in perspective of the upper end of the vertical post, showing the camsurfaces which form bearing-surfaces for the cam upon the lockinglever. Fig. 4 is an enlarged view in perspective of the lockinglever.

Reference now being had to the details of the drawings by letter, A designates the top of a bench, table, or other secure object, to which is bolted or otherwise firmly secured the inner end of a bracket arm 13. This bracket-arm B is, at a point adjacent to its outer or free end, provided with an annular opening, through which is passed the lower end of the upright or post 0, said hole being at its upper end reamed out to receive the beveled portionD of the post, and at its lower end the said opening is cut away to form a beveled surface, as shown at E.

F is a lever, one end of which is sleeved upon the lower end of the post 0, the lever being held against accidental displacement by a nut G, but the lever is allowed sufficient play to permit of its being readily turned when it is proposed to effect a looking or releasing of the post in its socket, as will presently be explained. The head or inner end of the lever F is provided with an inclined upper face corresponding in its angle of inclination with the angle of inclination of the cut-away portion E upon the post. It will thus be seen that by turning the lever F the post 0 may be readily drawn firmly down into its socket or may be released at will.

At a point adjacent to its upper end the post 0 is provided with a horizontal opening similar in all respects to the opening in the outer end of the bracket-arm just described, and within this horizontal opening is sleeved the inner end of the stub shaft or axle H, the said stub shaft or axle beinglockedin place or released at will by the turning of a lockinglever F, which lever and its connections are in all respects similar both in regard to their form and operation to the locking-lever F and its connections, it being provided with an inclined or beveled surface I to engage an inclined or beveled shoulder J upon the post 0,

and thus secure the locking effect desired.

K is an arm which rises from the upper end of the post 0, and at a point a short distance above the end of the post it is bent at right angles and extends horizontally over and parallel with the stub shaft or axle H, the free end of the said arm being bent downward and at its extreme end being provided with a bevel L corresponding with the bevel or angle of the cutting edge of the matcher or planer head. In use the matcher or planer head the knives of which are to be adjusted is placed upon the stub shaft or axle H, and the several connecting parts of the device having been secured by turning the locking-levers F and F the matcher or planer head is turned upon the axle and each of the cutter-blades is adjusted by bringing the edge of the blade into contact with the beveled end L of the arm K, as will be readily understood.

Having thus described my invention, What I claim to be new, and desire to secure by Letters Patent, is-

, A device for adjusting the knives of cutterheads,c01nprisin g in combination the bracketarm apertured at its outer end, the under side of which bracket-arm having beveled surfaces adjacent to said aperture,the post 0 mounted in the latter, and having a beveled shoulder D, the locking-lever E mounted on the lower end of said post and having cam-surfaces bearing against the beveled surfaces of the bracket-arm, the stub-shaft mounted in an aperture at the upper end of said post and having a beveled shoulder, the beveled surfaces J, and locking-lever F with cam-surfaces adjacent to said beveled surfaces J, and the bracket-arm K swiveled in the upper end of said post and having its outer end downwardly bent and beveled, as set forth.

In testimony whereof I affix my signature in presence of two Witnesses.

SAMUEL S. FARNEY. Witnesses:
