WATCH-=MAKERS LATH E.
SPECIFICATION forming part of Letters Patent No. 363,000, dated May 17, 1887.
Application filed December 3, IP36.
T aZZ whmn it may concern.-
Be it known that I, ED\VARD RIVETT, of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in \VatclrllIakers Lathes, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention consists in combining with the shears and head-stock of a lathe certain new devices, the objects of which are to increase the automatic features of the lathe, so as to render it much more useful as an instrument; also, to render it capable of working upon articles atall angles with equal accuracy, and to so construct the several parts that the slide rest may be readily attached to the tail-stock of the lathe; also, to improve the details of the tool-holding parts of the lathe. These objects I accomplish by themechanisms shown in the accompanying drawings, in which- Figure l is an elevation of the lathe with my improvements attached. Fig. 2 is a plan of the same. Fig. 3 is a view taken partly in cross vertical section and partly in end elevation, the view being taken on section-line Z Z of Fig. 2. Fig. 4 is a perspective of an improved tool-holder which I use in my sliderest. Fig. 5 is an end elevation of the improved tool-holder; and Fig. 6 is a cross-seetion through my improved tool holder, taken on the line y y of Fig. 4.
Although my lathe is more especially adapted to watch-w0rk, it may be used on all kinds of work requiring great accuracy, and may be adapted to be used on quite large lathes, and its use may be varied to an unlimited extent.
In the drawings, Arepresents the bed ofthe lathe, which is supported by a standard, A, and is provided with ways for the head-stock, tail-stock, and other similar parts to slide upon.
The head-stock B, Figs. 1 and 2, is made substantially as other head-stocks of this class are made, and is provided with a clamping device, B for attaching it to the bed of the lathe; also with coned pulley B, hollow spindle 13', back handle, 13, chuck l3, and other parts similar to those in use and this kind of a lathe, none of which requires a particular description, as they are well known and in common use.
Serial No. 2-10.62]. (No model.)
The tailstock, which I will now describe, is peculiar in its construction and use, and consists of a base or sliding piece, 0, Figs. 1, 2, and 3, upon which is mounted a post, 0", which, together with the sliding base-piece C, may be clamped to the bed A by means of the bolt 0' and hand-screw C, Fig. 3.
The post C has a circular graduated base, 0', 2, and is free to turn on its perpendicular axiswhcn the clampingscrew C, Fig. 3, is loose. A zero-mark (not shown) is made on the base-piece C, by the aid of which and the graduation (J' on the base of the post 0 the vertical plane forming the front face of the said post may be set at any horizontal angle with the axial line of the lathe.
To the front face of the post 0", I attach, by means of the clamping screw-bolt C, Fig. 1, and hand screw 0', a gage-rest device, which consists of a base-piece, 1), Figs. 1 and 2, held by the screwbolt (f, and being adjustable l0ngitudinall y across the face of the post 0, having no other motionexcept its motion with the post Uthat is, it will slide back and forth with the post on the axial line of the lathe, and it will turn with the post so as to form any desired horizontal angle with the axial line of the lathe.
1*], Figs. 1 and 2, is a slide that is moved back and forth across the axial line of the lathe upon the slide 1) by means of the screw and crank I) I) D", 2. To the slide E, by means of a pivot, (not shown,) I attach a swiveling baseplate, E" I E. This base-plate ID E" is clamped into position by means of a wedge-key, E, and a screw, E Fig. 2, and may be set at any angle in the plane of slide it, and has graduation on the part E as shown in Fig. 2. The base-plate E E E (see Fig. 2) has upon it a sliding block, II, which serves as a base for the toolpost 1*. Said tool-post K is attached by a pivot, (not shown,) and swivels on the block H, being clamped to said block by means of the wedge-key and screw device at K, same as shown at Eand E, Fig. 2, for holding the base-plate E E E, above referred to.
\Vithin the tool-post K, I have a tool-holder, K, and clamping-chuck K, Fig. 2, made in the usual manner, and provided with a lock ing device, L 142 L, Figs. 3 and 4.. This lock- ICO ing device consists of athrottling-ring, L, and i a tightening-screw, L L -a well-known device that does not require further description.
K Figs. 2 and 3, is a hand-wheel for revolving the tool-holder and its parts.
K", Figs. 1 and 5, represents a notched or graduated disk for guiding the operator when using this device for cutting gear-wheels, and is connected to clutch-spindle S by a pin or other device in common use. The turning of the clamping-chuck spindle and chuck when a wheel-gear, W, Figs. 2and 3, is to be cutby the cutter W is regulated by an arm, K locked to the tool-holder K by a clamp, K, said arm K holding a spring stop or latch, K K, in Fig. 1.
When desirable to useabovedescribed gagerest and tool-holder in the ordinary manner,
the whole device may be removed from the I post 6 and placed upon the sliding base M, Fig. 1, and then clamped by the bolt M and hand-wheel M In Figs. 4, 5, and 6 I have shown'a modification of the tool-holder K This improvement consists in making in the tool-holder a hole for the tool V, that is not concentric with the hole in the tool-post K, and in making its kerfs radiate from the eccentric hole that holds the tool V. 'To equalize-the spring of the parts T T '1 under the pressure of the throttlingpiece L, althoughthe parts T T T are unequal in section originally, the cut T is made so as tomake them of about the same tension, and thus cause them to close in onto the tool V with about the same pressure.
The object of the eccentric tool holder T, Fig. 4-, is that the operator may make slight changes in the place of the tool V by simply a turning the eccentric tool-holder T, and with-- out changing the position of any of the other parts.
A graduation is made, as shown at 7r, Fig. 2, on the base of the tool-holder K, for convenience in adjusting the holder when beveled wheels are cut, said wheels being held by the tool-holder, and cut by acutter running in the lathe The tool-holderK has clamping chuck at its end adjusted to tools of all descriptions, and also to receive and hold work, or, in other words, articles to be actedupon by cutting, milling, and other tools connected to a device driven by thelathe-spindle; but the tool-holder T, Figs. 4, 5, and 6, has. an eccentric clamping-chuck, and is especially adapted for holding tools which require slight changes in their place or angular relations to the work in the lathe.
As the outside diametersof the tool-holders K and T are the same, itis evident that either will fit the tool-holder K equally well and may be interchanged.
The tool-holding clamping-chucl': K, Fig. 3, 1
is of the kindsometimes called a split chuck,
surrounded by a quill, (like K Fig. 3.)
By my-construction of the gage-rest and tailstock, as described, I am enabled to change the machine that I call a lathe, and which in itself is a'most perfect lathe, into'a. millingmachine capable of doing any work required of a milling-machine.
I claim- 1. In a lathe, the combination of the bed A, and sliding tail stock 0 G and gage-rest toolsupport D,vwith the adjusting parts E H K and their adjuncts, connected as described, whereby the lathe is converted into a milling- ,machine, substantially as described, and for the purpose set forth.
2. In a lathe, the combinatiou,with thebed A and sliding base-pieceO, of the revoluble --tail-stock part 0 and gage-rest support D, operating together substantially as described,
and forthe purpose set forth.
3. In a lathe, the combination of the bed A,
sliding base 0, and re'voluble tail-stock part C, with the gage-rest support D, tool-holder K, tool-post K, and clamping-chuck K alloperating together substantially as described,
and for the purpose set forth.
