11.81.1112. TURNING LATHE.
No. 46,152. Patenne'd Jan. 31, 1865.
UNITED STATES .PATENT OFFICE.
DWIGHTYSLATE, OF HARTFORD, CONNECTICUT.
IMPROVEMENT lN TU RNlNG-LATH ES.
Specification forming part of Letters Patent No. 46,152, dated January 3l, 1365.
To all whom it may concern.-
Beit known that I, DWIGHT SLATE, of Hartford, in the county of Hartford and State of' Connecticut, have invented certain new and useful Improvements in Turning-Lathes 5 and I do hereby declare that the followin g is a full, clear, and exact description of the same, reference being had to the accompanyingdrawings,` and to the letters of reference marked thereon.
My invention relates to that kind of turningla-the in which the arrangement for turning tapering and curved forms consists in giving to the cutting-tool a motion in and out to and from the axis ofthe lathe-spindle, in combination with the longitudinal motion ot' the feedcarriagc.
Iam aware that several devices have been invented and patented for producing 4the above-described movements of the tool, among which I may mention those ot' J ames S. Brown and E. K. Root; but these have in practice proved somewhat objectionable, either by being inconvenient'in working and adjusting, inaccurate-in action, or of expensiveadaptation.
It is the object of my invention to produce "an arrangement of parts for giving to the tool inventions, intcrvenes between the upper or tool carriage and the lower ori'eed carriage, whereby 1 insure greater solidity and more precise action of the tool. i
v.To these ends my said invention consists in the employment, in connection with the feed and tool carriages, and with a guide-bar located at the back ot the lathe, ot' a connectin g-bar, formed and arranged substantially as hereinafter described, which connects the toolcarriage with the guide-bar through the adjustin g-screw of the said carriage in a manner which will be clearly explained and my said invention also consists in attaching the connecting-bar which controls the tool-carriage to the guide-bar by means of a slide jointed to the connecting-bar, and so formed, substantially as described, as to lock onto the guidebar, and thus give to the tool-carriage positive i movements both in and out.
To enable others skilled in the arts to make and use my invention, I will proceedto a description thereof, referring to the accompanying drawings, making part of this specification, in which- Figure l is a plan of paris of a lathe with my invention applied thereto. Fig. 2 is an end view ot` the same with the tail-block removed. Fig. 3 is a vertical section at line A A, Fig. l, drawn on a large scale. Fig. -i is a vertical section at line B B, Fig. 3. Fig. 5 shows the connecting-bar fin detail. Fig. 6
is a cross-section of the guide bar g, and Fi g,
7 shows the slide l. in detail. y
Similar marks of reference denote the same parts in the several igures.
a is the bed of thelathe; l), the lower or feed carriage, which slides in the usual way on guides made on the top of the bed parallelv with the axis XX of the lathe-spindle, and c is the upper or tool carriage, which slides on guides formed on the feed-carriage at a right angle. with the axis X X.- These parts may have the general form and arrangement of corresponding parts in the lathes in most general use, and the lower or feed carriage may receive itslongitudinal movement by-any of the usual feed apparatus. The upper or tool carriage, c, is adjusted to the work by the usual screw, d, which is confined to .said carriage by'collars e e, Fig. 3. The nut for the adjusting-screw d, instead of being secured to the feed-carriage b, as is the case in lathes of ordinary' construction, forms part of a bar, f, which lies loosely in a groove in the top of the lower carriage, b. This bar j' projects beyond the carriage at the rear of the lathe, and its end is there jointed at h to a slide, which is locked onto a long ouide-bar r which extends nearl from end o LJ# to end of the lathe, and is so attached to the bed by ajoint-pin, i, and bolt k that it maybe inclined to the axis X X of the spindle. The guide-bar g is grooved near its edge through nearly its entire length, (see cross section, Fig. 6,) and the slide Z is locked onto the bar g by means of lips on m, Fig. 7, which enter the grooves in the guide-bar, and a gib or shoe, o, which is causedl to press against the edge ot' the guide-bar by setscrews p p.
s is a set-screw, by means of which the connectingbar f may be clamped to the lower earriage and secured thereto in case it may be desirable to detach the bar f from the slide l,
-when the-lathe may be used in the customary 4above description.
To make use of the apparatus it is necessary, first, to set the guide-bar g at the proper angle, then to adjust the tool to the work in the usual way by the screw d, and proceed as with the ordinary lathe. To adapt my inven tion to almost any of the usual forms of lathes it will only be necessary to furnish supports for the guide-bar to place a groove in the top of the lower carriage forthe reception of the connecting-bar f, and to t the nut in the connectinglbar to the adjusting-screw d ot' the tool-carriage. To turnforms havin g a curved profile, the guidebar may be formed to the are of a circle and the form of the slide l be adapted thereto; but if it be desired to turn forms having irregular profile, which will require the employment of a guide-bar having its edge of corresponding form or profile, the slide Z must be dispensed with and the end of the connecting-bar be armed with a properlyshaped shoe, which may be caused to press against and` follow the irregularities of the edge of the guide-bar by means of a strong` spring or by a weight acting on the tool carriage in a similar Way to the Weight which is used for a somewhat analogous purpose, described in the patent of J. S. Brown, before aliuded to.
It is obvious that a modification of my invention may be made by attaching the adjusting-screw of the toolearriage to the conneeting-bar f and the nut to the carriage Without departing` from the spirit of the invention.
Having thus described my invention and set forth its use, I disclaim the novelty of the guide-bar g but Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. The employment, in combination with the guide-bar g and with the adjustingserew (1,01' its equivalent, of the tool-carriage, ofthe connecting-barf, arranged substantially as hereinbefore set forth.`
2. The employment, in combination with the guide-bar and eonneetin g-bar aforesaid, of the slide l, jointed to the connecting-bar and locked to the guide-bar, substantially as and for the purpose hereinbefore specified.
In testimony whereof l have hereunto set my hand this 10th day of September, 1864.
DWIGHT SLATE.
