PATENT OFFICE.
JOHN J. GRANT, OF NEW YORK, N. Y.
BALL-GRINDING MACHINE.
Application filed Gctober 31, 1919.
To all whom it may concern.
Be it known that I, JOHN J. GRANT, a citizen of the United States, resident of New York, county of New York, and State of New York, have invented new and useful Improvements in Ball-Grinding Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
My invention relates to ball grinding machines, commonly referred to as dry grinders, its object being to provide a machine of this character wherein the discomfort and danger due to the formation of emery eliminated.
or similar dust arising from the abrasion is The said invention consists of means hereinafter fully set forth and particularly pointed out in the claims.
The annexed drawings and the following description set forth in detail certain mechanism embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.
In said annexed drawings:
Figure 1 is a plan of a ball grinding machine embodying my invention.
Fig. 2 is a vertical section taken upon the plane indicated by line II-II in Fig. 1.
Fig. 3 is a detail section taken upon the plane indicated by line III-III in Fig. 1.
The drawings illustrate a part of a machine which is completely shown and described in my co-pending application, Serial No. 334,686, filed October 31, 1919, such part being that which includes my present invention. In this machine, the disk H carries upon its lower surface an annular grinding wheel H whose lower surface is contiguous to a ball race formed by an an nular stationary disk A and outer stationary ring D and a rotatable annular ring 5 the latter forming the bottom and the two former the sides of the race.
The disk H is provided with a plurality of sectoral openings it. The correspond- Specification of Letters Patent.

Serial No. 334,687.
ing sides of these openings are inclined as shown in Fig. 3, and to these inclined surfaces are secured vanes H The inclination of these vanes is such that when the disk grinding wheel is rotated in the direction indicated by the arrow in Fig. 1, a current of air will be created in the interior of the grinding wheel to the exterior thereof. The dust formed during the grinding opera tion will therefore be drawn into the in terior of the grinding wheel, upwardly through the opening it and thereby removed from the vicinity of the machine and the operator.
What I claim is:
1. In a ball-grinding machine, the combination with a rotatable grinding member having sectoral openings therethrough; of means comprising vanes adjacent to such openings for removing dust from the vicinity of the grinding member.
2. In a ball-grinding machine, the combination with a rotatable grinding mem her having openings therethrough, corresponding sides of said openings being inclined; of means comprising vanes attached to the edges of such openings, for creating a current of air.
'3. In a ball grinding machine, the combination of a rotatable grinding member comprising a disk provided with sectoral openings therethrough and an annular grindii'ig wheel secured to the lower surface thereof, said openings being located above the central. opening formed by said annular grinding wheel; and inclined vanes secured adjacent to such sectoral openings.
4. In a ball grinding machine, the combination of a rotatable grinding member comprising a disk having sectoral openings th rethrough and an annular grinding wheel secured to the lower surface thereof, the lateral faces of said openings being inclined; and vanes secured to such faces.
Signed by me this 4th day of October, 1919.
