TURN-TABLE.
I SPECIFICATION forming part of Letters Patent No. 778,379, dated December '27,1904.
Application filed November 23, 1903. Serial No. 182,232.
' To @ZZ whom it may concern:
Be it known that I, ALBERTUs O. SLENTZ, a
I citizen of the United States, residing at Candeclare that the following is a full, clear, and exact description of. the same, reference being had to the annexed drawings, making ay part of this specification, and to the figures of reference marked thereon, in which Figure l is a top view showing a portion of the rotatable plate broken away. Fig. 2 is a horizontal section showing a transverse view of the annular trough and the antifrictionballs properly located therein, the view being taken at a point showing the highest elevation of the ball-trough. Fig. 3 is a sectional view cutting the ball-trough longitudinally.
The present invention has relation to turntables; and it consists in the novel arrange-- ment hereinafter described, andparticularly pointed out in the claims.
Similar numerals of 'reference indicate corresponding parts in all the figures of the drawlngs.
In the accompanying drawings, 1 represents the fixed base or foundation, which is formed of a size to correspond with the size of the turn-table designed to be constructed. The base l is provided with an annular groove 2, which annular groove is for the purpose of receiving the antifriction-balls 3, which balls are-located in the groove, substantially as illustrated in the drawings. The top plate t should 'be and'preferably is provided with annular iiange 5, which annular iiange extends downward and overlaps the periphery of the base l, substantially as shown in the drawings. For the purpose of reducing the friction of the balls the trough 3 is formed upon its bottom face with depressions or elevations which might be termed serpentine in form, thereby providing the elevated points 6 and inclines leadingup and from said elevated points in eitherdirection. -In use any desired number of elevated points such as 6 may b e employed, reference being had tothe size of the turn-table designed to be constructed and also time when the balls are upon the points or elevations 6 and that the balls locatedin the trough intermediate the elevations will be free or clear from the bottom or under side of the plate 4, by which arrangement no contact will be maintained upon the balls intermediate the elevations, thereby leaving the balls free to be moved or rolled in the trough between the elevated points, the balls being moved by the ones coming in contact with the rotatable plate as they pass over the summits or high points, it of course being understood that as the plate is rotated thel balls on the summits will become the driving ones for the balls that have passed down the inclines and into the trough.
The object of forming the trough as above described is to give to the rotatable plate but few contact-points and .said contact-points so located that the rotatable plate will be held in a true position with reference to the base l and the,I trough.
For the purpose of giving the basel the desired amount of strength` the base should be provided with the arms 7, said arms being so formed that one of the connecting-points of each of said arms will come upon opposite sides of the summit, this feature being illustrated in Fig. l.
journal point for the table it should be provided with the journal 8, which journal rotates in the aperture 9, formed in the base l. For the purpose of reducing the friction and the wear of the balls the depressed portions ofthe trough may be provided with any suitable lubricant, and of course the balls as they pass through the lubricant will to a certain extent become submerged in the lubricant contained in the trough. l
Having fully described my invention, what For the purpose of providing a center ore I claim as new, and desireto secureby Letters groove provided with a series of alternating depressions and elevations, balls adapted to travel in the groove and each elevation adapted to support a ball, and amovable plate supported upon the balls on the elevations, and the movable plate journaled in the socket of the base, substantially as and for the purpose specied.
2. In a structure of the class described, the combination of a fixed base provided with an annular groove, said groove provided With a series of elevations and depressions, balls adapted to travel in the groove and up and down over the elevations and up and down through the depressions, and the elevations each adapted to support a ball in the path oi travel, and a movable plate supported upon the balls While on the elevations, substantially as and for the purpose specified.
In testimony that I claim the above IV have hereunto subscribed my name in the presence of two Witnesses.
