OVAL-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 618,889, dated February 7, 1899.
Application filed March 2, 1898.
To all whom it may concern.-
Be it known that I, LoUIs MAROHAND, acitizen of the United States of America, and a resident of Allegheny, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Oval- Outting Machines, of which the following is a specification.
Figure 1 is an elevation of my device with the table removed. Fig. 2 is a like plan View. Fig. 3 is a broken view of the bed of the machine, showing the eccentric slide. Fig. 4 is an inverted plan View of the revolving table. Fig. 5 is a sectional view along the line :20 0c in Fig. 7. Fig. 6 is an elevation of my machine fitted with a vertical cutter. Fig. 7 is an elevation of my device complete fitted with a horizontal cutter; and Fig. Sis a plan view of the same, showing a piece of material undergoing the operation of cutting.
My invention, broadly stated, is a machine for cutting ovals in material of any character.
The following is a detailed description of my device.
1 is the bed of the machine, onwhich is erected cutter-frame 2.
3 is the cutter-arm, fitted to slide longitudinallyin frame 2. On the forward extremity of cutter-arm 3 is head 4, in which is adj ustably held stem 5, supporting horizontal cutter 6. Cutter 6 is provided with pulley 7, which is connected with pulley 8 by belt 9. Pulley 8 is mounted on power-shaft 10. Shaft 10 is journaled in bracket 11, which bracket is preferably made integral with the rear extremity of cutter-arm 3, thus maintaining a fixed distance between pulleys 7 and 8.
12 is a table fitted with slide 13, boxed there in, said slide being mounted on spindle 14. Spindle 14 passes through hole 15 in bed 1 and is revoluble by any known means.
16 is a cross-recess in bed 1, with beveled edges in which is fitted eccentric slide 17. 18
is a raised circular portion of said slide engaging recess 19 on the under side of table 12. The lesser dimension of recess 19 is parallel to the motion of slide 13 and is slightly greater than the diameter of 18, while the-larger dimension of recess 19 is at least nearly twice Serial No. 672,341. (No model.)
the diameter of 18, thus permitting 18 to re volve eccentrically in recess 19. 20 is a longitudinal slot in said eccentric slide 17, through which passes spindle 14.
21 21 are dogs of any usual design for holding the material on the table 12, and 22 represents a piece of material so held.
Fig. 6 illustrates my device fitted with a vertically-revolving cutter 6, mounted in journal 5 on stem 5 and fitted with pulley 7 t, to which power is communicated by belt 9.
The operation of my device is as follows: The material 22, on which the operation is to be performed, is fixed to table 12 by dogs 21 21. The length of cutter-arm 3 determines the major axis of the ellipse and is drawn out to the desired position, as indicated of scale 23 on arm 3. The minor axis is determined by the position of eccentric slide 17 in relation to recess 16. This is graded by means of scale 24 on slide 17. As slide 17 is drawn out it carries with it, by means of projection 18, table 12, which moves on slide 13, contained therein. Slot 20 enables slide 17 and table 12 to move eccentrically to spindle 14; but slide 13, being fixed to said spindle, remains stationary. Power is now applied to revolve spindle l4 and in turn slide 13, which causes table 12 to revolve eccentrically around raised portion 18 on slide 17. The material is thus so presented to the revolving cutter 6 as to cause said cutter to out an oval of the dimension of the determined ellipse.
My machine may be used in any case where oval cutting is desired on any material, and although I have described minutely the different parts of my device I do not limit my self to the particular parts enumerated; but
I claim, broadly 1. In oval-cutting machines, the combina tion of a bed; an eccentric slide adjustably carried by said bed; a projection on said eccentric slide; a revoluble spindle passing through said bed; a slide fixed to said spindle a table adjustably mounted on said slide and a recess in said table engaged by said projection.
2. In oval-cutting machines, the combination of a bed; a slide mounted in said bed and adapted to move transversely to the line capable of being extended over the surface of movement of a cutter-arm; a slotted block of said rotary table. 10 mounted on said slide; a spindle passing Signed by me, at Pittsburg, this 17th day of through said block and slide and secured to February, 1898.
5 a second slide; a rotating table in which said LOUIS MARCHAND.
second slide is adapted to reciprocate; and VViLnesses: means of engagement; between said rotating A. M. THOMPSON,
table and said slotted block, and a cutter-arm EDWARD A. LAWRENCE.
