ETAL=CUTTING MASHINE.
SPECIFICATION forming part of Letters Patent No. 655,424, dated August 7, 1900. Application filed September 22, 1899. Saris-1N0; 731,362; (No model.)
To all whom it may concern:
Be it known that I, SWAN J. VERNSTEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal-Cutting Machines, of which the following is a specification.
The object ofthis invention is the production of a machine to do that class of work which is now ordinarily done by hand with a file. It is especially adapted for finishing printers chases and other similar work.
In the accompanying drawings, Figure 1 is a side elevation of this machine. Fig. 2 is a plan view, and Fig. 3 is a front elevation, of the same. Fig. 4 is an under face view of the cutting-tool. Fig. 5 is an end elevation of the same. Fig. '6 is a side elevation of said tool; and Fig. 7 is a side elevation of the toolbearing arm, showing the relative position of its rocking cam.
Like letters of reference indicate corresponding parts throughout the several views.
In the construction of this machine I provide the body portion A, in the rear lower part of which I journal the drive-shaft B, having the tight and loose pulleys B and B at one of its ends and the pinion B fixed on its op-. posite end. Directly above the shaft Bis an intermediate shaft C, having the gear-wheel O and the pinion G rigidly mounted thereon.
The crank-shaft D is j ournaledin the upper part of the machine-body and has the gearwheel D fixed on said shaft. This gear-wheel meshes with the pinion O and is therefore rotated by the movement of the tight pulley B. The shaft D is provided with thetwo cranks D and D and has fixed on its longitudinal center the cam D A carriage E is mounted on the ways E, having a forward-and-back reciproca tory motion on said ways imparted by means of the connecting-rods E", which extend between the shaft E and the cranks D and D respectively. The tool-bearing arm F is also pivotally mounted on the shaft E near the longitudinal center of said shaft, and extending rearwardly rests upon the surface of the cam D. The peripheral contour of this cam is such that during the forward movement of the tool-bearing arm F the rear end of said arm is'slightly elevated, holding the tool in engagement with the work; but upon the return movement the rear end of said arm is permitted by the form of the cam to descend, raising the tool at the forward end of the arm awayfrom the work. The tooljF is secured to the forward end of the tool-bearin'g'arm F in any suitable manner. In this instance I have provided the two machine-screws F for that purpose. The cutting-face of the tool F is composed of the diagonal teeth F each successive tooth fromfront to man being a little longer than the preceding tooth of the tool to permit each to cut a chip in the operation of the machine. 7
G is a table for supporting the work to be operated upon. It is mounted on the vertical ways G and is adapted to be vertically adjusted by means of the threaded shaft G and the hand-wheel G in the usual manner. It is also supported within the transverse guides G the rack-bar G with the pinions G and thehand-wheel G7 providing means for the lateral movement or feed common in machines of this class. The clamp-bar G with itsset-screws G, and the movable vertical frame G with its setting-screws G provide means for clamping the work to be operated upon firmly in position on the table G.
In operation work is fastened on the table G and the machine started. The table is raised until the cutting-tool F engages with said work, each forward movement of the tool cutting as many chips from the surface of the work as there are teeth on the face of the tool. The peripheral surface of the cam is so formed that the tool will be held in engagement with the work during the forward movement of-the carriage E and the tool-bearing arm F and raised to clear the work upon the return movement of said carriage. The work is fed laterally under the cutting-tool by rotating the hand-wheel G and raised for another cut, if that is desirable, by turning the hand-wheel G I claim as my invention-- 1. In a metal-cutting machine, in combination, a body portion; Ways thereon; a car-' riage on said ways; a tilting tool-bearing arm pivotally mounted on said carriage; a cutting-tool fixed on said arm; a rotatable shaft;
a cam on said shaft, adapted to engage the tool-bearing arm for moving said arm on its pivot to raise the cutting-tool from engagement with the work on the backward stroke of said tool; and means for reciprocating said carriage, which means is independent of the tool-bearing arm.
