W. G. MERRELL. MACHINE FOR TURNING OVALS.
No. 10,412. Patented Jan. 10,1 54.
WM. G. MERBELL'OF AUBURN, NEW YORK.,
ACHiNE' FOB CUTTING EL IrsEs.
Specification of Letters Patent No. 10,412, dated January 10, 1854.
To all whom it may concern:
Be it known that I, WILLIAM G. MERRELL, of Auburn, in the county of Cayuga and State of New York, have invented a new and Improved Machine for Turning or Outting Ovals; and I do hereby declare that the following is a full, clear, and exact de scription of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which Figure 1, is a plan or. top view' of the machine. Fig. 2, is a side elevation of ditto. Fig. 3 is an inverted plan of the trammel plate and cutter stock. r
Similar letters of reference indicate corresponding parts, in each of the several figures.
The trammel plate is an instrument that has been long known and used by joiners, draftsmen, and various artisans for drawing ovals; it is merely a plate having two slots through it crossing each other at right angles, a stock having two pins through it fit in the slots in the trammel plate'a pin in each slotand to the end of the stock is attached the pencil. By turning the stock the pencil will scribe an oval in consequence of the slots causing the pins to work in right lines.
This improvement hitherto has never been successfully used for turning or cutting ovals in consequence of the difiiculty attend ing the application of quick speed to the stock. It is necessary that the stock should work steady and firm without play or tremor; I overcome the above difiiculties and effect the desired object by a simple arrangement of the cutter stock and a driving pulley as will be presently shown, and which arrangement constitutes my invention.
To enable others skilled in the art to make and use my invention 1- will proceed to describe its construction and operation.
A, represents a frame constructed in any proper manner and on the upper part of the frame is placed a trammel plate B, having two slots a, a, through it and crossing each other at right angles see Figs. 1, and 3.
On the upper part of the frame are two transverse ways 0, C, which intersect the edges of the trammel plate B, at opposite points, the ways being parallel to each other and projecting upward a suitable height above the plate B.
Under the trammel plate B, there is acircularledge or projection D, see Figs. 2, and 3. Thisledge or projection is secured to or it may be cast with the trammel plate. It projects downward asuitable distance be low the trammel plate as seen in Fig. 2.
E, is the cutter stock at one end of which is secured the cutter F. The stock has two pins or screws 6, b, which pass upward through the slotsa, a, one through each slot and also pass through a driving pulley'G which rests or bears on the ways G, C, as seen in Fig. 2. The pins or screws 6, 6 have 7 nuts 0, c, ontheirupper ends, by turning these nuts the pulley G may be made to bear x firmly upon the "ways 0, G, and the cutter stock E, against the circular ledge or projection D, on the under side of the trammel plate.
A band H, passes around the pulley G, and around the pulleys I, J; power being applied to the pulley J, and communicated by the band H, to the pulley G; the pulley I, merely causing the band to have an entire bearing around the pulley G. j j The cutter F, as the stock E, and pulley Gr,- rotate will cut in an oval form and the cutter as it is moved will not be subject to any vibration or tremor because the cutter stock E, works firmly against the ledge orv projection D, and the pulley G, on the ways K, is a bed on which the stuff to be cut in oval form is secured. The bed is placed horizontally beneath the cutter stock and is supported by four screw rods d', which pass through nuts 6, attached to the" bed. See
Figs. 1, and 2. Each screw rod has a pulley f, at its lower end and a chain g, passes around them and also around a pulley h, on
a shaftL, which is surmount-ed'by a hand wheel M. By operating this hand wheel the chain y, will turn the screw rods d, and as therods 03, work through nuts 6, on the bed,
the bed may be raised orlowered as desired and the stuff or work which is secured on the bed may be fed toward the cutter and lowered from it whendesired. O, are guides which steady the frame as it is raised'or lowered.
The cutter F, is fitted ina stock 7:,which i 2 works on a projection or cleat 2', on the cut- 'ter stock and a screw rod j, passes through V no the stock V V 7 On the outer end of the screw rod j, there is a small toothed wheel Z, which ast-he stock V I E, revolves catchesinto either-of the spring spurs m, 02, attached to the frame A, seeFig. 2. These spurs are elevated or depressed so as to act upon the Wheel Z, by means of dogs 0, 39, attached by rods 7", 1*, to a lever N; By
moving the top of the lever N, towardthe frame, the upper dog 0, will be depressed and the upper spur m,--will be forced downward sufiiciently to catch the teeth of the wheel Z, and move the cutter outwardon the stock a certain distance every timethe wheel 1, passes the spur. -By moving the leverN, in an opposite direction the reverse takes place, the lower dog 1), Will raise the spur n, which will catch the Wheel and turn it so as to move the cutter inward? By this arrangement the cutter may be moved either in orout onthestock E, as desired.
The above machine may be used "for cutting ovals, or .turning moldings in oval frames; different tools or cutters being employed according WOIk.
to the character. of the p I do not claim the employment of the trammel for that is well known as an old device, neither do I claim the method of raisingand lowering the bed, that being also an old device, but
What Ido claim and desire to secure by Letters Patent is' The manner in which the driving pulley G, and cutter stock E, is made to rotate firmly on the trammelplate '13; viz: having the ways C, C, on'the upper surface of the trammel plate B, and a circular ledge or projection ID, on a the under surface, and causing the pulley G, and cutter stockto press firmly against the ways and ledge or' projection by means of the pins or screws 6, b, and nuts 0,0, as herein shown and described. a i
