To all whom 'it 'may concern:
Be it remembered that I, REUBEN CAVE, of the city of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvement in Machinery for Grinding or Polishing Saw- Blades and Knives or Any other Metal Article with a Flat Surface with a Long Bevel; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same and also the improvements, reference being had to the drawing on le in the Patent Office of the United States, which was sent with my application for a patent for said machine, which drawing is made part of'this specilication for my improvement, in which-- Figure l is a side elevation; Fig. 2, an end elevation. Fig. 3 is a plan.
F is the frame.
L is a plumber block forbearing the upper stone.
O is a gum spring.
stone. lwisthe under stone.
B, B, are pulleys.
H, H, are hand wheels.
W, W', are a pair of miter wheels.
S, S, are screws by which the upper stone is regulated. v
The construction and operation of this machine: Two grind stones running edge to edge opposite ways, one immediately above the other, and both running at the same time, the upper stone running onethird faster than the under one. The article polished by reason of the upper stone running faster than the other, rests between the stones, without any apparatus to hold it while it is being polished. From two to sixteen, knives one and one-quarter inches wide, or two saws, can be polished at. the same time.
The stones are three feet in diameter, and
leighteen inches thick, and with two horse ledge to edge in opposite directions one immediately above the other` (and both running at the same time) the upper stone running faster than the under one.
REUBEN CAVE.
