IMPROVEMENT IN' LATHE FOR ISQUARING NUTS, Bcc.
The Schedule referred to in these Letters Patent and making part of the same To whom it may concern.-
Be it known that I, JAMES FLOWER, of Detroit, in the county of Wayneand State of Michigan, have invented a new and useful Improvement in Lathe-Attachment for Squaring Nuts and other like articles; and I do declare that the following is a true and accurate description thereof, reference being had to the 'accompanying plates of drawings and to thel letters of reference marked thereon and being a part ot' this specification, in which- Figure 1, plate 1, is a frontelevation of my squarin gmachine.
Figure 2 is a plan view of the same.
Figure 3, plate 2is a side elevation of the, same as attached to a lathe, and showing the operation of the tool in squaring a nut.
Figure 4 is a vertical section of the same.
Like letters indicate like .parts in each ligure.
The nature of this invention relates-totlie construction of a device to be attached to and operatingin connection with a lathe for squaring the sides of nuts and similar articles.
It consists in the peculiar construction and arrange-y ment, on a bed-plate transversely secured on the ways of a lathe, of certain adjustable standards, sustaining yan adjustable center for the work to be faced, and an adjustable chuck in which the work is secured, and in combination therewith, an ndex-plate, so divided off as to present as many faces of the work tothe action cfa half-lipped drill, rotating with the head-spiiidle of the lathe, as may be desired, speedily finishing each facet in uniform size with the rest. and effecting a great saving in files, time, and labor, besides securing greater uniformity than. is possible where such work is done by hand.
In the drawings- A represents a.u bed-plate, transversely secured to the ways B of a lathe. f
C is a rest, dovetailed in ways on the bed-plate, receiving its motion from a screw, D.
In transverse dovetail ways on the rest a standard,
E, is erected, receiving its motion (parallel with the ways of the lathe) from a screw, F, as shown in tig.4.
The edges 'of the upright part of the standard are ways, on which are placed two brackets, G and H, the lower one, G, receiving a vertical motion from a screw, I, at the back of thc standard.
On the end of the bracket is ai'ccntcr, a, on which the nut or work to be faced is centered.
The upper bracket is adjusted in like manner by the screw j,
' Ou the. cuter end of this bracket an index-plate, K, is journaled, whose center is coincident with that of the center a. below.
The index-plate is laid o so as to bear-rested by a pin, b, passing through one of the holes in the strut c, projecting from the upper bracket, four, six, or eight times in a rotation, or as many times as may be desired to presentnew faces of the work to the action of the tool. l
L is a chuck, whose jaws, (l, are caused to approach or recede fi'om the common center by the ri,f htandleft screw M, and are designed to grasp and hold the work when it is centered ont-he center' (t.
In fig. 3 is shown the operation of the tool N, rotating with Vthe lathe-spindle. The tool is a squareedged drill with one lip ground away, as this form of tool is easier sharpened and trucd than the doubley lipped drill of ordinary construction.
rlhe operation 0f the device is as follows:
A nut to be squared or faced is driven on a inandrel, the lower end of which is centered at (t, and the upper gripped in the jaws ofthe chuck. The work is then adjusted to the plane of the drill N, and fed up to it by the feed-screw F. The standard is then moved across the face of the drill by the screw l), which, in its rotation, removes the metal from the surface ofthe nut. The drill being ground on side as wcll as ou end, cuts away the metal so as to leave a shoulder. rlhe piu b is then removed, and the index-plate rotated to bring the next hole under thc strut, and is secured by the piu again. '.lhis brings another face of the nut to the action of the drill, and the operation is repeated until all the sides of the nut are presented to the action of the drill, producing a nut whose sides or faces are uniform in size.
Any convenient number of nuts may be placed on 4 a mandrel and squared up, in one adjustment of the mandrel on the center and in the chuck, as well as a single nut. All squares or hcxagons on cocks, faucets, or similar work, can be finished up in like manner.
What I claim as my invention, and desire to sccure by Letters Patent, is*
l. The construction and arrangement ot' thc indexplate K, provided with pin b and strutc, and chuck L, rotating in thel bracket H, as and for the purpose ,set forth.
2. 'lhe construction and ,arrangement ot' the bedplatc A, rest (.l, standard E, brackets (l 1I, center a, index-plate K, chuck L, adjusting and feed-screws D, F, I, J', and M, substantially as described and for thc purpose specified. v
' JAMES FLOWER.
