NITED STATES PATENT OFFICE.
JAMES E. F.,LELAND, OF BOWLING GREEN, KENTUCKY.
IMPROVEMENT IN CENTERING DEVICES FOR GAGE-LATHES.
Specification forming part of Letters Patent No. 173,027, dated February 1, 1876; application filed January 3, 1876.
To all whom it may concern:
a cross-section, taken through the line fr,
Fig. 1.
Similar letters ot' reference indicate corresponding parts.
The object of this invention is to furnish an improved centering device for lathes, to enable blank handles and other pieces of wood to be quickly and accurately centered, so as to prevent imperfect work and loss ot' stock from inaccurate centering, and to increase the working capacity of the lathe.
The invention consists in the combination of the disk, the adjustable guides, and the spring with the mandrel ot' a lathe, as hereinafter fully described.'I Y v A represents the bed of the lathe, to which is hinged the bar Bby\a rod, G, attached to said bar B, and sliding in eyes D, attached to said bed A. To the bar B are attached three studs, E, to the outer ones of which are attached screw centering-pins F, to receive the outer ends 0i' the pattern G and the work H In the center stud revolves the mandrel I, to which motion is given by a, belt, which passes around its middle part, the stud E being slotted to receiveit.
One end of the mandrel I receives the end of the pattern G, and its other end receives the end ot' the blank H. J .is a disk or wheel, the hub of which fits upon the mandrel, and is connected to it by a tongue and groove, or other convenient means that will give it a free longitudinal movement upon the mandrel I, whilecompelling it to be carried around by and with said mandrel in its revolution. The
'disk J is held forwardby asspiral spring, K,
The inner arms of the guides L are placed radially upon the face of the disk J, around the end of the mandrel I, with' their side edges in grooves in lugs rformed upon the said disk J, Where they may be secured in place adjustably by clamping-screws or other convenient means. y
The guides L may be bent at right angles, or they may be bent at an acute angle, so that their outer arms may be inclined from the mandrel I, as shown in Fig. 1. M represents the cutter, which is pivoted to the bed A, and is driven by a band iu the usual way.
In using the device, one end of the work H is placed upon the screw center-pin SF. Its other endis placed Within-the guides L,against the mandrelI, and a turn or two oi' the center screw-pin F secures it upon said mandrel I. As the work is turned forward the` blank HK As thebar B is moved back, thev disk J is\- forced into its former position by the spring K. One end of the arm P is secured to 'the bar B, and its other end rides in a groove in the hub ot' the disk J. When the work has no longitudinal movement, and the cutting-toolis moved along it, the said cutting- Y tool should be provided with a pin or projection to push back the disk J, and withdraw the guides L from the end of the work.
Having thus described my invention. I claim as 'new and desire to secure by Letters Patent- The combination of the disk J, the adjust- 'y 'l able angular guides L, and the spring K with the Amandrel I of a lathe, substantially as herein shown and described.,
JAMES E. 'F.LELAND. Witnesses:
