UNITED v STATES PATENT OFFICE.
PARLEY HUTCHINS, JR., VOF WORTHINGTON, MASSACHUSETTS.
IMPROVEMENT IN MACHINERY FOR TURNING BWLS.
Specification forming part of Letters Patent No. 5,306, dated September 25, 1847.
To all whom t may concern:
Be it known that I, PARLEY HUTcHINs, J r., of Worthington, in the county of Hampshire and State of Massachusetts, have invented a new and useful Machine for Turning Wood Bowls or Dishes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,referencebein g had to the annexed drawings, making a part of this specification, in Which- Figure lis a perspective View; Fig. 2, a top view, with part of machine taken out.
The letters are the same forthe same parts in both views. Y
The nature of my invention consists in turning bowls or dishes from blocks of wood or any other suitable material by means of one or more knives shaped in a curved form and placed ina frame made for holding them, which frame being' made fast to the middle of a semicircular arm, said arm having cogs or teeth which are operated upon by an endless screw for the purpose of moving the said semicircular arm and knife-frame up to the revolving block of wood for the purpose of turning olf bowls or dishes, as set forth and hereinafter described.
A represents the chuck, on which the block of wood is secured and from which the bowls or dishes are to be turned; B, pulley, which gives motion to the chuck A; @stationary bottom piece; g g, standards for mandrel, which contains the chuck; C', movablefbottom con taining endless screwD and semicircular arm E with knife-frame F.
The bottom of movable frame C moves on slides a a; e e, dac., cogs or teeth on semicircular arm E, knife-frame F fastened to the middle of the semicircular arm E at one end, the other end turning upon pivots d d; G G,
Adto., turning-knives; H, lever for securing rmly the knife or knives; I, movable piece containing the gouge Jy K, screw for regulating the gouge; L, spring which acts upon the movable frame C', M M, pins which prevent the movable frame from sliding too far.
V is a setscrew,which, in conjunction with the clasp W on the center-pin U, adjusts the chuck and center pin longitudinally, and thereby moves the block of wood with regard to the knife so as to determine entirely or in conjunction with the sliding frame C the thickness of the bowl to be cut. l
To enable others skilled in the art to make and use my invention, I will proceed, to describe its lconstruction and operation.
The chuck A is elevated to a properl height for the operation of the machine, being fixed on onelend of a mandrel 'l with a set-screw V.
The other end of the mandrel receives the pulley B, by which motion is given to the chuck A, holding the piece of wood from which bowls or dishes maybe turned. A center-pin U holds wood by means of the endless screw D, acting A upon cogs or teeth e e, dac., on the outside of a part of the semicircular arm E. The other part of said arm E and nearest to the chuck A contains a gouge J, secured to a movable piece I. The gouge is for the purpose of turning off the outside of the round part of the block, as represented in the annexed drawings, an'd which is done previous to putting the knives in their frame.
The movable piece I, containing the gouge J, works upon a pivot f, and is moved forward or backward by means of a screw K, as described above. l i
I make the turning-knives in any of the known modes for turning curves, and curve them to suit a small or large curve, having one for every size bowl or dish that I Wish to turn or cut from a block of Wood. The turningknife is fastened to a piece o'f wood or iron, and is let or set into the knife-frame F, then held to its place by the lever H until the operation of cutting or turninga bowl is completed. It is then lifted up and the knife taken out, when a smaller knife is substituted for cut ting a smaller bowl .from the piece of wood yet left unturned, &c.
To facilitate the operation of turning 0E bowls or dishes, as above stated, I employ one, two, three, four, or more knives at a time by putting them in one frame, andV cause each knife to turn off its own bowl or dish, as
shown in Fig. 2 of the annexed drawings, and
any number.' of knives are, when properly varranged in said frame, held together and made permanent by means of said lever H, as before described, and, as in case where only one knife is used.
The operation of my machine is commenced by setting the pulley B in motion, which turns the mandrel which contains the chuck A, whereon that piece of wood or block is affixed from which it is intended to turn bowls or dishes. The semicircular arm E is moved around by means of the endless screw D working in the cogs e e, dac., on the periphery of a part of the semicircular arm E toward the chuck A, thereby bringing the knife or knives in knife-frame in contact with the block of Wood which is revolving` rapidly, causing the knives to enter and cut one or more bowls or dishes in a very short time, using one or more knife or knives for the performance of the above said operation. The mandrel T, its setscrew V, and the center-pin U and itsfclasp W are intended' to operate in conjunction with the frame C and its fixtures in determining the thickness of the bowls or dishes to be cut when one knife is used. The movable frame C', containing the semicircular arm E, knifeframe F, endless screw D, &;c., runs upon the slides a, a. The object of this arrangement is to assist in accommodating the knife to the thickness and size of the block of wood and to assist in varying the thickness and size of the bowls or dishes. This is accomplished by the set-screw S, which moves the platform G toward or from the chuck A, and this motion brings the knife nearer to or farther from the external surface of the block. v
Having thus fully and clearly described the construction and operation of my machine for turning wood bowls or dishes,what I claim as my invention,and desire to secure by Letters Patent, is-
The combination of the semicircular arm E with the knife-frame F, holding one or more knives, and adjustable piece I, holding the gouge J, for the purpose of turning wood bowls or dishes, and, infcombination therewith. the
.manner of regulating the thickness and size of bowls or dishes to be turned off. by means of the sliding or movable bottom C and the adjustable mandrel T and center-pin U, for
the purpose of turning Wood bowls or dishes, in
the manner as herein set forth and described.
September 15, 1847.
