IMPROVEMENT IN CASTING TOOTHED CYLINDERS.
Specification forming part of Letters Patent No. 118,693, dated September 5, 1871.
To all whom it may concern:
Be it known that I, HARMON W. CORNELL, of Owego, in the county of Tioga and in the State of New York, have invented certain new and useful Improvements in the Mode of Casting Metal Oylinders 5 and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.
The nature of my invention consists in a new mode of casting metal cylinders with an uneven outer surface, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe the manner in which the same is or may be performed, referring to the annexed drawing, in which- Figure l is an end view, and Fig. 2 a longitudinal vertical section of the pattern used in my mode of casting metal cylinders.
A represents the core-block of my pattern, made of any desired size, and with eight sides, upon which are laid sections B B, completing the pattern. These sections maybe constructed in any desired shape, so as to make a round, oval, or
v any other shaped cylinder, either straight or taperin 0'. The outer surfaces of these sections may have teeth, corrugations, recesses, or projections of any kind, according` to the desired style of cylinder to be cast. The sides of every alternate section are made square, while the others are inclined, as shown in Fig. 1. In the center of the core-block A, at the upper end, is a short shaft, O, while at the lower end is a central hole, D, for
the insertion of a shaft. Upon each side of the core-block A, at the lower end, is a projection, a, with a corresponding recess, af, at the lower end of each section, and at the upper end of each section is a similar projection, b, with a corresponding recess, b', in each side of the core-block. The complete pattern thus constructed is placed in the mold and the sand built up all around the same inv the usual manner. The mold and pattern are then turned upside down, when the coreblock A is drawn upward out of the mold. After this every alternate section B, namely, those with square edges, can be moved inward and taken out, and, lastly, the sections with inclined edges. XVhen all are removed the regular round core-block is inserted, leaving between its outer surface and the mold the required space for the thickness of the cylinder. The metal is then poured into the mold in the usual manner, forming a solid cylinder, with teeth, corrugations, or projections on its outer surface, according to the pattern used.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The method herein described of casting metal cylinders with an uneven outer surface by means of patterns constructed and arranged substantially as herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 2d day of June, 1871.
HABMON W. CORNELL.
