MORGAN CHITTENDEN AND WILLIAM A. LYON, ()F DANBURY, CONN.
IMPROVEMENT IN LATHES FOR TURNING CVALS.
Specification forming part of Letters Patent No. 205,474, dated July 2, 1878; application filed November 13, 1877.
To all whom it may concern Be it known that we, MORGAN UHITTENDEN and WILLIAM A. LYON, both of Danbury, in the county of Fairfield and State of Oonnecti out, have invented certain new and useful Improvements in Lathes for Turning Ovals; and we do hereby declare that the following is a full, clear, an d exact description thereof, which 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.
Our invention relates to lathes for turning ovals; and the object is to produce a lathe by which ovals of different sizes and shapes can be perfectly and regularly turned in an expeditious manner.
The invention consists in a chuck-plate, to which the object-such as picture-frames, &c.
' to be turned is secured; and it is operated by two rings sliding against each other in recesses in an adjustable head-plate, so that they can be varied for different sizes of ovals. Each ring is provided with a central rod, which rods pass through a shaft at right angles to each other. The inner ring is attached to a head-plate on the driving-shaft, while the outer ring revolves loosely in an opening in the adjustable head-plate.
To more readily and regularly lubricate the rods, so that they will slide more easily through the short shaft, a wick is passed crosswise over one and then the other rods, all of which will be more definitely described hereinafter, reference being had to the accompanying drawings, in which- Figurel isa side elevation of ourlathe. Fig. 2 is a longitudinal section of the same. Fig. 3 is an end view of the same. Fig. 4 is an end View with the head-plate removed. Fig. 5 is a detail view of the rings, showing the lubricating-wick and rods.
In the drawing, A is a frame, with suitable bearings for a shaft, B, the inner end of which is provided with a plate, 0, upon the face of which a ring, D, is secured, and this has a central transverse rod, (1. To the lower part of the inner end of frame A an adjustable head-plate,E, is secured by a set-screw, a, and
moves up and down between guides e e, and has a slot, b, for adjusting it. It is operated by a pivoted lever, F, having a suitable opening through it, so that the setscrew a can be easily manipulated. The head-plate E is recessed on its rear side, so as to slide up and down over the ring D, while its outer or front side has an opening corresponding in size to the outer ring Gr, which is also provided with a central transverse rod, g. The rods d and 9 pass through a short shaft, H, at right angles to each other, and around them a wick, h, is arranged in reverse direction, so that the rods are constantly lubricated, and thus will more easily slide through the shaft H, and are pregented from sticking. The end of the shaft H is provided with a screw-thread, upon which a washer, I, is first screwed to close the openin g in the head-plate, and'then the chuckplate K, upon which the object to be turned oval is secured in any well-known manner.
The operation is as follows: The object to be turned oval being first secured to the chuckplate, the head-plate is adjusted to the size of oval required, and motion is then imparted to the shaft B by means of the pulleys B. The shaft B then revolves the shaft H by means of the ring Gfwhich moves in the opening of the head-plate E; and said ring G, with shaft H and chuck-plate K, being eccentric to the ring D and shaft B, is, by the rods 01 and g, moved in an elliptical or oval direction, and, the cutting-tool being stationary, the oval is made perfect.
The advantages of our improved lathe are, that it is very simple in its construction; not liable to get out of order; it can be readily adjusted for difi'erent sizes of ovals; it makes the ovals perfect and uniform; it can be furnished at a very small cost, and can be made of any size and material.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
1. In a lathe for turning ovals, the shaft B, plate 0, ring D, and rod d, in combination with the ring Gr, rod 9, shaft H, and headplate E, arranged substantially as shown and specified.
2. In a lathe for turning ovals, the combination of the shaft H, rings D and G,.rods d shaft H, adjustable head-plate E, and chuckand g, and the lubricating-wick h, arranged plate K, all constructed and arranged subas shown, and. for the purpose specified. stantially as shown and herein described.
3. The combination of the adjustable headplate E, lever F, rings D G, and. shafts B and Z H, all arranged as shown, and for the purpose set forth.
4. The lathe herein described, consisting of the frame A, shaft B, plate G,1'ings D G,
