IMPROVEMENT IN DRESSING MILLSTONES.
Specification forming part of Letters Patent No. 159,133, dated January 26, 1875; application filed October 31, 1874.
To all whom it may concern:
Be it known that I, JOHN WILLIAMS, of Dresden, in the county of Weakley and State of Tennessee, have invented a new and useful Improvement in Device for Dressing Millstones, of which the following is a specification:
The object of this invention is to provide means whereby millstones may be dressed accurately; and it consists of an iron or metallic frame, having slides which run in grooves, moved by racks and pinions, and two guides which connect the slides, between which is confined the marker or operating-tool, which is moved in the guides at right angles with the slides, the construction and arrangement of parts being hereinafter more fully described.
In the accompanying drawing, Figure l is a top or plan view of the device complete. Fig. 2 is a cross-section of Fig. 1, taken on the line a: at. Fig. 3 is a longitudinal section of Fig. 1, taken on the line y y.
- Similar letters of reference indicate corresponding parts.
A represents the frame, which is rectangular in form, with its bottom side faced off true in the planing-machine, and having upon its faced side two longitudinal pieces of wood, marked B, which are made and kept true with the frame by scraping or other means. 0 O are the slides, which are made to run exactly parallel with the faced bottom of the frame in a V-shaped groove by means of cogs in their upper sides, which engage with pinions D D on the shaft E. F is a hand-wheel on the end of the shaft. By turning this hand-wheel the slides B B are moved back and forth. Any other suitable kind of gearing may be used, instead of the racks and pinions, for moving the slides. These slides B B are connected together by the two guide-bars G G. These guides are moved back and forth within the space H, and carry the operating-tool I. The guide-bars are grooved, as seen at J, and the tool-handle K has a pin which runs in the grooves, so that the tool works parallel with the faced bottom of the frame.
The object of the device is to cut the face strictly with the staffed face of the stone, and by so doing retain the true face.
When the marker I is once properly set, it can be moved, by means of the hand-wheel, as much or as little as may be necessary to reach all the channels within the space H, and then the device readjusted on the stone.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the stationary baseframe A, the horizontal driving-shaft E, carrying pinions D D and hand-wheel F, the sliding rack-bars O G, the connecting-bars Gr G, and the dressing-tool I K, all constructed and arranged as herein shown and described.
JOHN WILLIAMS.
