Description
Dec. 7, 1937. LEHMANN 2,101,372
LATHE Filed Nov. 20, 1935 Patented Dec. 7, 1937 UNITED STATES PATENT OFFICE signor to Lehmann Machine Company, St.
Louis, Mo., a corporation of Missouri Application November 20, 1935, Serial No. 50,705
2 Claims.
This invention relates to lathes and more particularly to the sliding tailstocks thereof. It has for its principal object to provide for lubricating the ways along which the tailstock slides. Other objects are simplicity and cheapness of construction and compactness of design. The invention consists in the lathe tailstock and in the construction, combinations and arrangements of parts hereinafter described and claimed.
In the accompanying drawing, which forms part of this specification and wherein like symbols refer to like parts wherever they occur,
Fig. 1 is a side view of the rear end portion of a lathe provided with a tailstock embodying my invention,
Fig. 2 is a horizontal section on the line 22 of Fig. 1, with the tailstock base and supporting ways therefor shown in plan,
Fig. 3 is a vertical cross-section on the line 33 of Fig. 2,
Fig. 4 is a fragmentary cross-section on the line 44 of Fig. 2,
Fig.5 is a vertical cross-section on the line 5-5 of Fig. 2; and
Fig. 6 is a vertical longitudinal section on the line 6--6 of Fig. 2.
The accompanying drawing illustrates the tailstock end of an ordinary lathe comprising a bed I provided at its upper side corners with longitudinal ways 2 and 3, respectively, a base member 4 slidable along said ways, a tailstock 5 mounted on and secured by bolts 6 to said base member, a dead spindle I mounted in said tailstock, a hand wheel 8 for adjusting said spindle axially in said tailstock, and a handle 9 for locking said spindle in the desired position ofadjustment. The tailstock is slid along the ways of the lathe bed by means of a pinion III that meshes with a rack H on the lathe bed and is fixed to a shaft l2 that is journaled in a bracket l3 fixed to the tailstock base and is provided with a suitable operating arm l4. As shown in the drawing, the contacting surfaces of the way 2 and the tailstock are disposed in a horizontal plane; and the way 3 is of substantially inverted V-shape cross-section and cooperates with a similar V-shape groove 3a provided therefor in the underside of said tailstock base. The lathe construction thus far described is well known and it is unnecessary to illustrate it in detail.
As shown in Fig. 2 of the drawing, the tailstock base 4 comprises a frame having spaced parallel side frame members l5 and I6 that rest upon the ways 2 and 3, respectively, of the lathe bed and are integrally connected by end frame members I1 and by spaced intermediate cross frame members l8 and I9. Formed in the top surface of the tailstock base or supporting frame is a lubricant containing groove that is closed at its top by the tailstock5. Said lubricant groove has a portion 20, which extends longitudinally of the side frame member l6 of the tailstock base 4 from a point adjacent to the rear end thereof to a circular recess or pocket 2| located opposite the adjacent end of the intermediate cross frame member I9 of said frame, and a portion 20a, which extends longitudinally of said cross frame member from the recess or pocket 2| in the side frame I member iii to the side frame member l5 where it terminates in a pocket or recess 22. The tailstock base is provided with discharge passageways 23 that lead downwardly from the pocket 2| to the opposite sides of the V-shaped groove 3a. in the underside of said tailstock base; and the pocket 22 is likewise provided with outlet passageways 24 that lead downwardly therefrom to the portion of the underside of said base that rests on the way 2. Mounted on the tailstock base or supporting frame 4 is a cup or other suitable reservoir 25 for lubricant that communicates with the rear end of the portion 20 of the lubricant groove through a passageway 26 in said frame.
By the arrangement described, lubricant flows from the reservoir 25 carried by the tailstock base into the portions 20 and 20a of the lubricant groove therein and thence through the holes in the bottoms of the pockets or enlarged portions 2! and 22 of said groove base to the supporting ways and is distributed along said ways and the portions of the base cooperating therewith when the tailstock is moved along the lathe bed. The lubricant groove is easily formed in the tailstock base, and the entry of dust or other foreign matter into said groove is prevented by the tailstock which forms a cover therefor.
What I claim is:
1. In a lathe, a bed provided with spaced parallel ways and an open-work supporting frame comprising side frame members slidably supported on the respective ways and connected by cross-frame members, said frame having a lubricant containing groove in its upper surface that extends longitudinally of one of said side frame members and thence along one of said crossframe members to the other of said side frame members, said groove having enlarged pocket portions located in the respective side frame members opposite the ends of said cross-frame member, said side frame members having dismember to the other of said side frame members. said groove having enlarged pocket portions located in the respective side frame members opposite the ends of said intermediate cross-frame member, said side frame members having discharge passageways that lead downwardly from the enlarged pocket portions thereof to the 'respective slideways, and a reservoir for lubricant mounted on and movable with said frame for supplying lubricant to said groove.
