LATHE.
Specification of Letters Patent.
Patented May 30, 1922.
Application filed June 4, 1919. Serial No. 301,761.
T 0 all whom it may concern:
Be it known that I, GEORGE HAUMANN, a former subject of the Emperor of Austria- Hungary, (who has taken out his first papers of citizenship in the United States and has applied for his second papers,) and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Lathes, ofwhich the following is a specification, the principle of theinvention being herein explained and the best mode in which I have contemplated applying that principle, so as to dist1nguish it from other inventions. The present improvements relate more particularly to that type of lathe which Is for handling lighter work than the regular heavy engine lathe. In other words, the present improved lathe is designed to handle work of comparatively short length. The object of the invention is to provide a lathe of this type which Wlll not only be simple and compact, but of sufficiently rigid and substantial construction to enable just as heavy work to be handled thereon, except in the matter of length, as might be handled on the larger lathe. A further object is to insure precision in operation whereby accurate work will be at all times assured. A further object is to combine with a lathe of the type in question a convenient and readily accessible grinder for sharpening tools, such as may be employed on other lathes.
To the accomplishment of the foregoing and related ends, the invention, then, con-- sists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however. but 'one of various mechanical forms in which the principle of the invention may be used.
In said annexed drawings v Fig. 1 is a front elevation of my improved lathe; Fig. 2 is a central longitudinal section of the head stock and ad a- 3 is a transverse section through the head.
stock and adjacent portion of the bed, showing motor drive for work spindle; and Fig. 4 is an end elevation of such head stock showing arrangement of gears connecting work spindle with feed screw.
The frame or bed of my improved lathe is of extremely simple and yet 'i-gigid construction, comprising, as shown in the several figures of the drawings, a main tubular member 1 and supports 2 and 3 for the respective ends of said member. member 1 comprises simply a section of steel pipe ground exteriorly to true cylindrical form, and formed, preferably on its under side, as mounted in the aforesaid supports 2 and 3, with a longitudinally extending slot 4. The tail-end support 2 is simply a light casting formed with transversely spaced feet 5, while the other sup- Theport 3, which is formed with similar feet 6, rises above the tubular member 1, is hollow to receive the head stock mechanism presently to be described, and is closed by a removable cover plate 7 Journaled in suitable bearings 8 and 9, held between the upper face of such hollow support 3 and its cover 7, is the work spindle 10 which may be of any usual construction, such spindle preferably lying directly over the axis of the tubular bed 1 and in alignment with the dead center 11 that is adjustably mounted in the usual manner in. a tail stock 12. The latter is itself adjustably mounted on the bed 1, being carried by a split annular base that is slidable on said bed and is adapted to be secured in any desired place longitudinally thereof by a tightening of the clamp screw 13 so as to draw its split ends together. A
noted journaled therein below the spindle 10, said shaft carrying a worm 16 that meshes with a worm gear 17 on a second shaft '18 likewise-disposed below work SplIldle 10 but in parallel relationship therewith. Shaft'l5 constitutes in effect the prolongation of the armature spindle of an electric motor 19 (see Fig. 3), disposed to the rear of the head stock and housed in a suitable casing 20 directly attached to the support 3 which constitutes such head stock. The forward end of spindle 15 projects through the front wall of the support 3 and is adapted toreceive a grinding wheel 21 or other like device.
Two pairs of change speed gears 22, 23 and 24, 25 are keyed onto shaft 18 so as to be s'idable longitudinally thereof through the medium of suitable operating levers 26 and 27 respectively, thus bringing said gears into mesh with corresponding gears 28, 29 and 30, 31 on the work spindle 10. A variety of changes in speed between said work spindle and said shaft 18, or in other words the drive shaft 15, may be thus effected, it being observed that, as shown in Fig. 2, both sets of change speed gearson shaft 18 may be left in neutral, in which event the shaft 15 will run idle, as will be desirable when the grinding wheel 21 is in use. It will further be observed that the bearings for the spindles carrying levers 26 and 27 whereby these change speed gears are shifted, are held between the upper face of head stock 3 and its cover 7 just as are the bearings for the work spindle, thus facilitating the assembly of these parts in the, original construction of the machine, or their ready disassembly should it for any reason be afterwards desirable to get ac cess to the interior of the head stock.
The feed screw 35 is centrally supported in the tubular bed 1 having its respective ends journaled in bearings 36 and 37 provided in the corresponding supports 2 and 3 of such bed. The manner in which this screw is operatively connected with the tool slide or carriage 38 is clearly shown in Fig. 2, it being observed that such slide is mounted on a split annular base 39, slidably fitted on the bed 1 and provided with clamp screws 40 whereby its split ends are drawn together. A plate 41 is clamped between such split ends of base 39, and serves not only to hold the carriage in proper vertical position upon the bed 1 by slidably engaging the slot 4 in the latter, but is also formed with an interiorly threaded extension 42 within which the feed screw 35 is threaded. Rotation of the latter, it will accordingly be seen, will serve to move the carriage longitudinally of the bed in either direction, as desired.
For manual rotation of the feed screw 35 a hand-Wheel 43 is mounted at the tail end thereof, which projects beyond the corresponding support 2 with. this object in v1ew. For automatic feeding of the carriage, the other end of said feed screw 35 is adapted to be connected with work spindle 10 in the head stock through suitable intermediate gearing (see Fig. 4) such as is regularly employed in lathes. The gearing in question is enclosed in a suitable removable cover 44 attached to the outer end of head stock 3, and comprises a pinion 46 loosely mounted. on the projecting end of said shaft 18, which meshes with an intermediate gear 47 which meshes in turn With a large gear 48 on the end of the feed screw 35. The intermediate gear 47 is carried on an arm 49 swiveled about the axis of said screw, and,'by substituting gears of different diameters, the screw will be driven to feed the carriage in one direction at varying rates of speed relative to the rate of" rotation of the work spindle 10. An idler gear 50 is carried by an arm 51 swiveled about the axis of said shaft 18 so as to enable such gear to be interposed in the gear train between the spindle 10 and the feed screw 35, the effect being obviously to reverse the feed of the carriage. The tubular bed which forms one of the characteristic features of my improved -may be readily assembled and disassembled is another extremely convenient feature, quite aside from the direct interconnection of the motor spindle with the intermediate shaft through which the work spindle is driven. At the same time the motor spindle is utilized to carry a grinding Wheel in position most convenient to the operator. The compact disposition in the head stock of the change speed gears between the intermediate shaft and the work spindle, as well as the equally compact yet accessible disposition of the change speed gears between the intermediate shaft and the feed screw at the outer end of the head stock, is secured without sacrifice of convenience, but rather the contrary, the operating levers for said change speed gears being all close together and easily manipulated.
Other modes of applying the principle of my invention may be employed instead of -the one explained, change being made as regards the mechanism herein disclosed. provided the means stated by any of the followlng claims or the equivalent of such stated means be employed,
I therefore particularly point out and distinctly claim as my invention 1.
