Specicationj ofLettersVPatent No.l'6,000, dated `January 2,1849` To all whom t may concern:

Be it kno-wn that I, ARUNAH S. MooM- BER, of Bennington, int-hecounty of Bennington and State of Vermont, have invented'` a new and useful Improvement on a rIurning'- Lathe for Turning or ARimming Outthe Interior of Boxes for Carriage and v otherVVheels, whereby the said boxes can be turned or. rimmed out ofwany required taper in a superior manner. to any' other modeV known or usedgand I hereby do declare that the followingis a'full, clear, and .y

exact description;

The nature and principle of my invention consist in placing the box to be turned or rimmed out on a lathe within a. revolving.

chuck through which passes a ixedgspindle with a cutter attached to it and yconnecting the said chuck and stock head to a saddle, which by a slot or slots thereinland'pivots or 'centers connecting the. said saddle to the slide, allows the saddle, puppet Aheads and chuck to be set at any angle with the cutter on the spindle, whereby boxes of any required taper may be cut o-r rimmed out as the chuck revolves around the cutter and moves with the slide.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation, reference being had to the accompanying drawings making a part of this specification, in which- Figure 1, is a side, Fig. 2, yan end, and Fig. 8, a semi section vertical view.

The same letters indicate like parts on all the figures.

In Fig. l, a lathe of the common kind is represented, and those parts not implied in my invention need not be described.

A, is a fixed spindle, secured in proper bearings (fi) and (a2). This spindlecan be taken out at pleasure by unscrewing the screw bolt at (w). e

B, is the cutter' or chisel rmly secured to the spindle. (0,) (0,) are puppetvheads made in the usual way and firmly secured by bolts or pins to the plate or saddle D, represented in Fig. 3.

E, E, is the revolving chuck, resting in the puppets, and exhibited as protruding therefrom in Fig. l. (o) represents set screws passing throughthe chuck to key or hold firm the box placedmwithin thechuck to be turned or rimmed out.

4supportedand held secure in the-chuck` turning around withthe'chuck.'

' 1 G, 'is' the puppet stock. It is planedand secured to. DLthe saddle'.l l

H, H,is a` sliding"fla-ingeA or plate frame" having mgmoren theunderfpartyon each side, toallowit to slide transversely on the arefpivotszto 'act as centersfor swivels, fori the saddle when movedon'H, H, at any'V angle with the cutter onthe'spin'dle.

L, L, L, L,are screws working through eyes` on the. sldemflangevH, with their points-or ends pressingthe 'sides of th'e'saddle so as "to f hold it rm and-secure onfthe slide and also at i the pointor angle. with the cutter, at' which itmay be set. -l f Mu is a screw Iworked by 'a handle N."-

It passes thr'ghaneye in the slide and an eye on the Hange H, H, to hold the two firm and solid together and also for allowing the flange'to be moved somewhat f. transversely on the rails lof the slide as seen in Fig. 2. All the parts described are constructed in theV usual manner, with the exception of the pivots K, K, working in the slots .seen

in Fig; 3, whereby the-saddle D, can be setat any angle with the cutter. The saddlev can be moved transversely onthelatheand set angularlyf on "it likewise by the pivots,

"K, K, acting asswivels orcenters, for Athe saddle. The slide flange H, H may be moved somewhat transversely on the slide, but cannot bsetat'any angle with the cutter, as the saddle can be, therefore, it is by I the manner inwhich D, is constructed and operated fthatboxes for carriages &c. can be turned or rimmed out of any taper required.

To do this, the operation is `as "a follows: Let` the box to be turned or its v interior rimmed out, beplaced in the chuck,

as represented in Fig. 2, and if Ifdesire toV rim it out, I loosen the screws L, L, in their eyes and move the saddleJ I), transversely` on H, H, (and thus" the stock, puppets and chuck and box with it) unt-il the inside of the box at one side presses against the knife or cutter chisel B. I then set the chuck in motion (having first made it secure and firm'by the screws) by t-he driving band X, which passes down to the driving shaft, and as the chuck revolves around the spindle and the slide moves in the usual way, the cutter by being in contact with the inside of the box F, while the chuck the chisel, than the center of the other end of the box is set from the cutting line. The less taper that is desired in boxes, the more nearly equidistant from the cutter point are the centers of both ends of the box in the chuck set, and the greater the taper wanted, the center of one end of the box, is set at a greater, or the greatest distance from the cutting point while at the Vsame time, the center of the other end of the box is set more near. the cutting line of the cutter. By this mode of setting the saddle D, (and with it the box to berimmed out) atany angle with the cutter point, one end of' the box if need be may be rimmed or turned out and the other end not touched with the cutter at all. The points, or angles at which the saddle and its movable parts, may be set with the cutter point, can be exactly determined by having an index on the upper surface of the flange H, H, and a pointer attached to the puppet stock G. This plan of rimming orv turning out the interior of iron boxes of any required taper for Wheels &c., can be easily attached to every lathe and for rimming out cylinders, it will allow of a far shorter cutting chisel than is now Vemployed for such a purpose, thereby saving both money and labor.

Having thus explained the nature of my l invention, its construction and operation, I do not claim the combination of the saddle D, with the puppets, and'chuck, and flange on the A cutter on 'the lixed spindle, so that? when the box and chuck revolve around the cutter,- and with the slide as it moves horizontally on the bed of the lathe, boxes for carriage and other wheels may be turned or rimmed out of any required interior taper substantially as set forth.
