JOHN B. ROMANS, OF NASHVILLE, TENN ESSEE.

TURNING-LATHE.

SPECIFICATION forming part of Letters Patent No. 297,635, dated April 29, 1884.

Application tiled September 11, 1883. (No model.)

To 0. whom it may concern.-

1 Be it known that I, JOHN B. ROMANS, a

shown in the drawings.) The tail-block citizen of the United States, residing at N ashville, in the county of Davidson and State of Tennessee, have invented a new and useful Turning-Lathe, of which the following is a specification, reference being had to the accompanying drawings. I p

This invention relates to turning-lathes;

and it has for its object to provide a simple,

efficient, and inexpensive lathe, upon which, Without regard to the dimensions of saidlathe, cylindrical work of any desired length may be turned as easily, accurately, and effectively as may be done upon lathes the dimensions of which are made to correspond with the dimensions of the work to be performed.

lVith this end in view my invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims. r

In the drawings. hereto annexed, Figure 1 is a side elevation, partly in section, of a turning-latl1e embodying my improvements, and Fig. 2 is a detail view of one of the supporting-brackets.

The same letters both figures.

The lathe-bed or shears, which in the drawings are designated by letter A, are of the usual well-known construction, and with regard to these parts no novelty is herein claimed.

B designates the tail-block, which is also of the usual construction, and arranged to be moved upon the shears by. means of the feed screw or other well-knownv mechanism. (Not B is provided with a stationary spindle, O, which has a longitudinal perforation, D, at the front or inner end of which is mounted a chuck, E, of suitable construction to hold and retain securely in position the rod or other material which is to be turned.

F designates the head-block, which may be either stationary or adapted to be in any suitable manner adjusted upon the shears atthe upper end of the lathe-bed. The said. headblock is provided with bearings for a longitudinally-perforated spindle, G, having a conerefer to the same parts in *of the spindle G carries a -chuck,

laterally-extending rods or brackets pulley,H, whereby it is adapted-to receive motion in the usual mannerfrom the trcadle or other motive power of the lathe. The speed of the said spindle may also be regulated in the usual well-known manner. Theinner end I, which is provided with one or more radial cutters of any desired construction, for the radial adjustment of which suitable provision is made.

The ends of the lathe-bed are providedwith K, carrying the sliding supports L, which are shown in detail in Fig. 2 of the drawings, and which consist of suitable frames having forked arms at their upper ends adapted to support the work which is being turned upon the machine. The frames L have collars M, by which they are fitted to slide upon the rods K, where they are adjustable by means of set-screws N. It will be seen that the supports L, when not in use, may '-be moved close to the ends of the lathe, while the supporting-rods K may be slid under the bed of the latter.

The operation and advantages of this invention will be easily understood by those skilled in the art to which it appertains when reference is had to the foregoing description and to the drawings hereto annexed. A rod of any desired length may be adjusted in the hollow spindle of the tail-block and fed bythe latter through the-revolving spindle of the head-block carrying the cutters, whereby the said rod is trimmed to the desired dimensions. When the rod has been fed the length of the shears,the tail-block is movedback and again attached to the rod, after which the operation may be repeated. The ends of the rods during operation rest upon the crutches of the supporters L, and'will thus avoid vibration, which might otherwise interfere with the successful operation of the device.

This invention is simple and efficient, and by it Iam enabled to large dimensions with lathes of a comparatively small size. V V

I claim as my invention and desire to secure by Letters Patent of the United States- 1. In a lathe, the combination,with the bedframe A, of the laterally-extending rods K, ar-

operate'upon work of roo ranged to slide in thebed-frame, and the adj ustable supports L, having the collars M andthe In testimony that I claim the foregoing as 10 my own I have hereto affixed my signature 1n presence of two witnesses.

JOHN B. ROMANS.
