LATI-uam` SPECIFICATION forming part of Letters Patent No. 367,246, dated Julyz, 1887.
' i Application tiled March 5, 1887. Serial No. 229,873. (No model.)
To all whom it 7a2/ay concern:
Be it known that I, SAMUEL SLAYTON, a citizen of the United States, residing at Chicago, in the county of Cook and- State of Illinois, have invented a certain new and useful Improvement in Lathes, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of a lathe embodying my invention, Fig. 2, a sectional view of the same taken on the line 1 l of Fig. l; Fig. 3, a plan section taken on the line 2 2 of Fig. 2; Fig. 4, a sectional view taken on the line 3 3 of Fig. l Fig. 5, a sectional view taken on the line 4 4 0f Fig.l 1, and looking in the di'- 1 rection of the-arrow; Fig. 6, a sectional View taken on the line 5 5 of Fig. l, and looking in the direction of the arrow, and Fig. 7 a detail plan view of the tail-stock detached.
Like letters refer to like parts in all the iigures of the drawings.
My invention relates to lathes, and has for its object to produce a lathe containing various improved features, by means of which the tion of the same shall be improved; and to these ends my invention consists in certain novel features, which I will now proceed to describe, and will then particularly point outv in the claims.
In the drawings,A represents the bed of the lathe, which is mounted on suitable legs or supports, B, firmly attached to each end thereof. Upon its rear side this bed is provided with a suitable way, A', having beveled or undercut edges to receive the head-stock and tail-stock, which are mounted upon said way in the manner shown more particularly in Figsp and 6 of the drawings. The headstock C is provided with a suitable recess, c, to fit upon the way A', a key, C', being arranged within the said recess and Vclamped against the way by means of screws c', to secure ythe head-stock firmly in position upon the said way. The tail-stock D is provided with a similar recess, d, to t upon the way A', so that it may be longitudinally adjusted therein, and a key, D', is secured at one end 5o by an ordinary screw, d', and at the other end by a'screw, D2, provided with a handle by means of which the key D' may be readily slackened or tightened in order to permit the t tail-stock to be adjusted and to be secured after adjustment. It will be observed that the way A', although located on the rear of the lathe-bed A, is inclined somewhat forward, so that the spindles which are mounted in the stocks will bein line with the ce'nterof the lathe-bed, although their supporting-way is entirely to the rearof said central line, thereby giving the lathe-bed a clear front in order to not obstruct the movements of the slidefor feeding the slide-rest carriage are arranged,
so that' these parts and their co operating mechanism are cffectually protected from dust and dirt and the cuttings which may fall from the work mounted in the lathe. A similar recess, a', may be formed in the under side of the lathe, so that all superliuousmaterial in the lathe-bed is dispensed with and a light, and at the same time strong, lathe-bed produced.
The slide-rest carriage E,which is mounted, as hereinbefore described, on the front of the lathebed,upon the way A2 thereon,is provided with the usual longitudinal. feeds or feeding` mechanisms-both a screw-,feed by means of the screwF driven `from the head stock in the usual manner, and an automatic rack-and-pinion feed driven from the said screw and capable of being convertedinto a hand-feed when desired. These features are well known and common in lathes of this description, and I therefore, will not describe the same here. By their means the slide-rest carriage E may be fed longitudinally upon its ways in the desired manner. Upon the carriage E is mounted avertical slide, G, moving in suitable ways therein, and actuated by means of a feed-screw, G. This feed-screw is journaled vertically in the slide, as shown more particularly in Fig. 2 of the drawings, and passes through a nut, e, attached to the carriage E. A bevelpinion,g,is secured to the feed-screw G and meshes with a corresponding bevel-pinion, g', on the inner IOO end of a horizontal shaft, G2, the end of which projects outward beyond the front surface of the slide G,and is provided either with a keyhead, g2, to receive a suitable wrench or key for turning the same, or with a hand-wheel or lever for this purpose.
G3 represents an indicator mounted on the front of the slide G, upon the bearing of the shaft G, and consisting ofa disk having suitable divisions marked upon its margin to form a scale, and g3 represents a pointer which is secured upon the shaft G2 to cooperate with the said indicator-disk, upon the graduated margin of which its extremity rests. rlhe pointer g3 has a split or divided hub surrounding the shaft G'l and connected by a clampscrew, g4, so that the said pointer may be adj usted around the shaftG2 and clamped thereon after adjustment. By this means the precise height to which the slide G is raised by means of the feed screw G may be easily read upon the indicator-disk G", and when it is desired to move the said slide upward or downward a fixed distance from the position which it occupies t-he pointer g" may be readily adjusted around the shaft G'i,so as to point to the zeromark on the indicator-disk, and then secured upon its shaft. The desired movement may then be given to the slide G, and the extent thereof may be accurately read by means of the indicator.
Hrepresentsarevolving head mounted upon the top of the slide G, the connection being shown in the present instance as effected by means of a frusto conical hub, h, extending downward through a suitable recess of corresponding shape in the top G4 of the slide G, and having a threaded extremity, h', on the under side of said top G", upon which is mounted a clamping-nut, H'. rIhe head G of the slide G is semicircular in shape at the front to correspond with theshape ofthe front portion of the head H, which is graduated, as shown, to indicate the precise angular position of the head, an index-mark being placed upon the head G* for this purpose at the center of its front margin. It will thus be seen that the head H may be adj usted to any desired angle in relation to the slide G, and may be secured after adjustment by tightening the clamping-nut H in an obvious manner.
In suitable ways in the head H is mounted a table, I, provided on its upper surface with suitable T-grooves to receive either a tool-post, in case the table be employed to carry the tool, or a vice to hold the work, in case the table be employed to carry the work. In this latter case the work may also be bolted directly upon the face of the table, if necessary or desirable. lThe table I is given a cross-feed by means of a feed-screw, I', journaled in a suitable bearing, i, in the table I, and provided at its outer end with a hand-wheel, by means of which it may be revolved. The said feed-screw I' extends through a suitably-threaded aperture, i2, in the head H, or a fixed nut in said head may be substituted therefor. By this means a cross-feed may be imparted by hand to the table I. In order, however, to provide for the said table a power cross-feed which shall be operative at any angle of its adjustment, and which may readily be thrown in or out of gear, as desired, I have devised the following construction:
J indicates a bevel-pinion, mounted to revolve in a suitable recess in the head H, and held from longitudinal movement therein, the said bevel-pinion being splined upon the feedscrew I', so as to rotate with the latter, but not to move longitudinally therewith. This pinion meshes with a corresponding bevel-pinion, j, on the upper end of a shaft, J', which latter shaft has its axis coincident with the axis of revolution of the head H, and which derives its motion from the main feed-screw Fthrough suitable connecting mechanism. In the construction shown the shaft J' extends downward vertically through the hub h and its screw-threaded extension h', and also through suitable bearingsin the slide G, in all of which it is vertically movable, its lower end rest-ing upon an adjusting-camJ', upon a short crossshaft, J2, provided at its outer extremity with a handle, jt', by means of which said shaft and cam may be rotated to raise or lower the said shaft J', and thereby throw its pinion 7 into or out of gear with the pinion J. Upon theshaft J' is mounted a pinion,j3, which meshes with an elongated pinion, k, upon a short vertical shaft, K, mounted in suitable bearings in the carriage E. The shaft K is also provided with a bevel-pinion, k', which meshes with a corresponding bevel-pinion, Z, on a shaft, L, also mounted in the carriage E, and provided at its inner end with a wormwheel, L', with which a worm, L1, splined on the main feedscrew F, engages. It will thus he seen that when the shaft J' is moved upward to cause its pinion j to mesh with the pinion J on the feed-screw I', movement will be transmitted from the main feed-screw F to the said feed screw I', and will thereby automatically feed the table I across the lathe-bed. It will also be seen that since the axis of the shaft J is coincident with the center of revolution ofthe head H, thesaid head and the table I, mounted thereon, may be turned to any desired angle without in any way affecting the operation of the automaticcross-feed. Ihisantomaticfeed may also be thrown out of gear, when desired, by simply lowering the shaft J through the medium of the mechanism described for that purpose.
In order to provide an efficient bearing and support for the tail-spindle of the lathe, I construct the tail-stock bearing in the following manner. The spindle M is mounted in the bearing N on the tail-stock D in the usual manner, but the said bearing is divided along the plane of the axis, as shown at n, for quite a distance from the end thereof, and is further divided circumferentially at right angles to the former line of division, as shown at n', this second cut being carried half-way round the bearing. The split bearing thus formed IOO Ifi
is provided at each end with opposite lugs, O and O', through which pass adjusting-screws o, by means of which the said split bearing may be tightened at both ends, or, in other words, adjusted to takeup any wear which may occur. Between these adjustingscrews is located a clamping screw, P, by means of which the bearing may be readily clamped and Vunclamped to permit adjustment of the tailspindle in the usual manner.
The operation of my improved lathe will be readily understood from the preceding description, and therefore needs no detailed eX- planatiou. It will be seen that I provide a lathe having a light and strong bed, which will effectuall-y protectthe feed mechanism from dirt and cuttings, and will give to the carriage a free and unobstructed movement from end to end. It will also be seen that the vertical adjustment of the tool or work holding `table may be accurately determined by means of the indicator provided for that purpose, and that an automatic cross-feed at any desired horizontal angle may be given to the said table.
Various modifications in the details of construction may be made without departing from the principle of my invention, and I thereforedo not wish to be understood as limiting myself strict-ly to the precise details hereinbefore described, and shown in thedrawings.
Having thus described my invention, what I claim as new, and desire to secure by-Letters Patent,'is-r f l. In a lathe, the lathe-bed A, provided with the way A on its rear side to receive the head and tail stocks, with the way A2 on its front side to receive the slide-rest carriage, and hav` ing the recess a, open at the front only, to receive the feed mechanism, substantially as and for the purposes specified.
