JACOB R. SCOTT, OF NYAOK, NE\V YORK.
SKIVING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 439,433, dated. October 28, 1890.
Application filed June 28, 1890- Serial No. 357,111. (No model.)
To aZZ whom it may concern.-
Be it known that I, JACOB R. Soorr, a citizen of the United States, residing at Nyack, in the county of Rockland and State of New York, have invented new and useful Improvements in Skiving-Machines, of which the following is a specification.
This invention relates to certain improvements in skiving-machines, as pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 represents a front view, partly in section. Fig. 2 is an end view. Fig. 3 is a plan or top view. Fig. 4: is a plan of the table detached. Fig. 5 is a longitudinal vertical section of the table in the plane 00 at, Fig. 4. Fig. 6 is a transverse section of a modification.
In the drawings, the letter A designates a frame or standard, which forms the bearings for a shaft 13,011 which is mounted the cutter C.
D is the oscillating segmental table, which is intended to support the material to be acted on by the cutter. This table is movable in the direction at right angles to the axis of the cutter, and in the example shown in the drawings the table forms the segment of a circle, and it is provided with a shank a, having an eye 1), into which fits a screw-stud d. This screw-stud is secured in a slide 6, which is adjusted 011 a rod f by means of a set-screw g. Said rod slides up and down in eyes h h, formed on the ends of arms which extend from the frame or standard A, and its upper end is secured firmly to a slide 2', which moves on guides formed by the frame A. The lower end of the rod f rests upon a lever E, which has its fulcrum 011 a pin j, so that by depressing the inner end of said lever the table D is raised and by releasing said inner end the table is permitted to sink down until the slide 6 strikes the lower eye 71-. On the rod f is adjustably secured a slide 7;, which serves to limit the upward movement of the table.
The table is provided with a handle F and with a clamp G, which is hinged to the side of the handle and engages teeth Z formed in the surface of the table when the tail n is drawn backward. By this clamp the work is retained upon the table against the action of the cutter.
II is a guard which extends over the cutter and prevents the clamp G or the fingers of the operator from coiningin contact with the cutter.
The surface of the table D is provided with a cavity m, the shape of which depends upon the articles to be skived. The machine illustrated in the drawings is intended particularly for skiving stiifeners for the counters of boots and shoes, and the shape of the cavity m is made as indicated in dotted lines in Fig. 4 and in section in Figs. 1 and 5. In Fig. 4c the counter-stiffener is shown in position to be act-ed upon by the cutter, and when it has been adjusted, as shown, the table D is swung backward until the stop 0 strikes the slide 2'. Then the inner end of the lever E is depressed so as to raise the table and force the work against tl1e cutter G. As the cutter comes in contact with the work in the line 25 t, Fig. &, it acts upon those portions of the same which extend beyond the cavity m, and this action continues while the table is being moved in the direction of arrow 1, so that one half of the work is exposed to the action of the cutter. The table is then lowered and moved forward, the work is turned round and adjusted so as to bring its remaining half in position to be acted upon by the cutter, and then the table is raised and drawn forward, as already described.
It will be readily seen from this description that the action of the cutter upon the work depends chiefly upon the shape of the cavity 712, and it is obvious that for different kinds of work this shape must be changed; but for connter-stiffeners the cavity m is made so that its depth decreases gradually from its middle towards its rear, so that the middle portion of the stiifenerretains the desired thickness, while the edges are trimmed down as required; and by the aid of my machine I am enabled to skive such articles as counterstiffeners with uniform exactness and with great rapidity.
It must be remarked that for certain arti- V cles the table D may be made fiat and the cutter concave, as shown in Fig. 6.
What I claim as new, and desire to secure by Letters Patent, is-
1. In a skiving-machine, the combination, with a rotating cutter, of a pivoted oscillating work-supporting table, a vertically-movable support for the pivot of the table, and means for raising and lowering the support to raise and lower the oscillating table, substantially as described.
2. In a skiving-machine, the combination, with a rotating cutter, of a pivoted oscillating work-table having a concave face, a vertically-movable support for the pivot of the table, and means for raising and lowering the support for adjusting the table to and from the cutter, substantially as described.
3. In a skiving-machine, the combination, with a rotating cutter, of apivoted oscillating Work-supporting table provided With an attached clamp for securing the Work thereupon, a lengthwise-movable rod supporting the pivot of the table, and lever mechanism for moving the rod to adjust the table to and from the cutter, substantially as described.
4. In a skiving-machine, the combination, with a rotating cutter, of an oscillating table provided With a work-receiving cavity which gradually decreases in depth, a movable support for the table, and lever mechanism for adjusting the support to move the table to and from the cutter, substantially as described.
5. In a skiving-machine, the combination, with a rotating shaft carrying a cutter, of a pivoted Work-supporting table oscillating in 0 a plane at right angles to the axis of the cutter-shaft and having a cavity which gradually decreases in depth, a lengthwise-movable rod carrying the table, and means for moving the rod to adjust the table to and from the cutter, substantially as described.
6. In a skiving-machine, the combination, with a rotating shaft carrying acutter, of an oscillating segmental table having a cavity which gradually decreases in depth, a vertically-movable rod supporting the pivot on Which the segmental table oscillates in a plane at right angles to the axis of the cutter-shaft, and lever mechanism for raising and lowering the rod to move the segmentaltable to and from the cutter, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
JACOB R. SCOTT.
