MACHINE'FOR GRINDING AND PoLlsI-HNG BALLS.
SPECIFICATION forming part of Letters Patent No. 423,512, dated March 18., 1,890.
Application filed March 3l., 1888. Serial No. 269.185- (No model.) l
To all whom it may concern:
Be it known that I, JOSEPH V. CLARK, a citizenof the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Machines for Grinding and Polishing Balls, of which the part of this specification, Figure l is a side elevation of my device. Fig. 2 is a front View.
Fig. 3 is a section taken at the line 0c Fig.
3J?. Fig. 4l is a section taken at the line y y, ig. 2.
The frame A has the yoke B dovetailed to it and adapted to move vertically in the grooves. A lug a projects from the frame A and has a screw a screwedl through it. The yoke B rests on the screw d and is adjusted vertically by means of it. The shaft C is supported between the arms b of the yoke B. The preferred form of bearing for the shaft C is that shown inthe drawings, where bearing-screws b', passing through the ends of the vyoke-arms, are received in socket-s in the ends of the shaft. A clamp-screw b? is provided, which holds in place the bushing b3, the latter receiving the screw b. W-hen desired, the
.entire shaft C maybe withdrawn through the upper yoke-arm by loosening the screw b2.
The disk D is clamped to the shaft C by any suitable means.l Its lowersurface is provided with the polishing and grinding facing d, which vis preferably an emery-disk. The lower disk E is preferably provided with a hub e, and the wholev is centered on the axle F. The lower part of the axle F is provided with an annular flange f, which, being received into a corresponding recess in the hub e, serves to support the lower disk. The axle F is supported on the bracket A', projecting from the stationary frame A, The plate Gis attached to the top ofthe axle Fand occupies a space between the two disks, preferably touching neither. This plate G is ,of irregular outline, it being shown star-shaped in Fig. 4. In the same plane with plate G is the plate G', supand bicycle-bearings.
width, exists between them. The disk being Y iXed in position by its attachment to the frame A, the space between the disks is regulated by the adjusting-screw a.
The device is employed for grinding. and
polishing various kinds of balls-for eX- ample, such as are employed in roller-skates It is also employed in shaping and polishing balls of any description which require to be absolutely spherical,
&c.
The mode of operation is as follows: The balls in the rough are placed 'in the channel g and motion imparted to one of the disksfor instance, the disk D-by a band passing around its h'ub d. This causes the balls to rotate, and a secondary rotation in the opposite direction of thelower disk is then produced; or the lower disk may be `fixed or positively rotated in the saine or opposite `directionby a driving-belt around its hub e,
or, as is preferably the case, be left free to rotate by the revolution vof the balls being ground. IVith the irregular channel as a guide, the balls are turned' in every direction and are soon reduced to a perfectly spherical shape, and are highly polished. It is notnecessary that the polishing-'disk d should be attachedto the upper disk D, although preferably so. The exact shape of the channel g is not important. n It should be irregular in shape so as to insure turning the balls in all directions. v The sharpness of its curves will such as billiard-balls, balls for check-valves,
depend upon its Width, and the relation of the size of the balls to the diameter of the disks.
'The plates forming the 'channel maybe omitted and a channel cut in the lower disk. The lower disk may be employed to positively rotate and to have a roughened disk and be vemployed to grind the balls, and'in such case the upper disk may be allowed to be freely rotated by the balls being ground or be positively rotated and have roughened surface and assist in positively grinding the balls. In the device as shown in the drawings the IOO lower disk is smooth and case-hardened and the upper disk is roughened.
What I claim as new, and desire to secure by Letters Patent, is-
1. In a machine for grinding balls, the vcombination of two opposing plates and an intermediate plate or portion provided with a channel extended around the axis of the plate` and approaching to and receding from the said axis, substantially as and for 'the purposes specified. v
2. The combination of two concentric opposing disks or plates provided with drivinghubs, an intermediate plate having channel alternately approaching and receding from the axis of this plate, a shaft to which one of the disks is Arigidly attached, and an indesubstantially as and for the purposes set forth.
' 4.. The combination ot disk or plate D, polishing-disk attached to disk D, shaft C, supported in vertically-adjustable yoke B and having disk D rigidly attached to it, axle F, surrounding shaft C, plate G, mounted on axle F and concentric with disk D, disk E e, centered on axle F, bracket supporting axle F and disk E, and plate G and bracket supporting it, the plates G and G being so related as to form between them a channel approaching to and receding from .the center of said plate G, substantially as and for the purposes hereinbefore set forth.
5. The combination of frame A, provided with luga, screw d, yoke B, provided with arms b, shaft C, disk D, rigidly attached to shaft C, disk E, and bracket A', supporting plate G', substantially as and for the purposes mentioned.
6. The combination of the concentric disks D and E and the provision for guiding the balls located between disks D and E altervnately to and from the center and the periph- .ery ot' the disks, substantiallyas and for the purposes specified. ,Y
7. The combination of the upper arm b, bushing ha, set or clamping lscrew/"b2, bearingscrew b', shaft C, lower arm b, and bearing A-, substantially as and for thepurposes specified.
' JOSEPH V. CLARK.
