Unirse STATES PA'rnNr rtree@ ABEL D. CATLIN, OF BAY CITY, MICHIGAN.
CYLINDER FOR COTTON-SEED-HULLING MACHINES.
SPECIFICATION forming part of Letters Patent No. 380,787, dated Api-ii. 10, 1888.
Application filed April 15, 1887.
To all whom/ it may concern:
Be it known that I, ABEL D. GATLIN, a citizen ofthe United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Cylinders for Cotton-Seed-Hulling Machines; and I do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention appertains to improvements in` cotton-seed-hulling cylinders, and relates more especially to improvements in the class of hulling-cylinders which are formed of a hollow cylindrical shell cast of material of such hardness that ordinary tools cannot be used for turning and boring and fitting up the same to a suitable forni and finish for practical use.
rIhe objects of the invention are to construct the cylinder in such a manner that it will be more firm and solid and more durable and reliable, and so that the cost of' construction and repairs will be'greatly reduced.
The invention consists in the combination, arrangement, and construction'of the parts, as I hereinafter more fully describe and claim, and is illustrated in the accompanying drawings, in which- Figure l is a side view of the cylindrical shell, partlysectional. Fig. 2 is a longitudinal central section of a hulling-cylinder embodying my invention. Fig. 3 is a transverse section of the same at :v fr. Fig. 4 is an end view of the same. Fig. 5 isa view of the opposite end. Fig. Gis a View of the shaft carrying the heads of the cylinder and the balance in.
a represents a hollow cylindrical shell cast of an alloy metal of suitable hardness or of chilled iron, and is provided upon its periphery with the projecting ribs b. A portion, c and c', of each end of the central opening or chamber d of the cylinder is formed beveling inward or with a less diameter at its inner edge than at its outer edge. y
e is a shaft passed through the central cham'- ber, d, and is providedf"upon each end with Serial No. 234.929. (No morlcLl suitable journals, fand g. A cylindervhead, Zz, is rigidly secured to the shaft e, and is provided with an inclined or beveled periphery coinciding with the bevel ofthe end opening, c, but is of considerably smaller dialneter, so that when the head is passed into the opening in the end of the cylinder a space, Z, will be left between the periphery of the head and the inclined portion c.
t' is a cylinder-head fitted to pass upon the shaft e, and is constructed similar to the head h, and is arranged to pass into the end of the cylinder opposite the head h, and with a space, Z', between the periphery of the head andthe cylinder, as in the opposite end,
A portion ofthe shaft e is provided with a screw-thread, j, and a nut, 7c, is passed upon the shaft and engaged with the thread j.
The end portions, c and c', of the cylinderopening cannot be finished in a true and perfeet manner for receiving a machine-fitted head without great expense and trouble on account of the hardness of the material thereof, and in order to form a true and perfect bearing for the heads the spaces Z and Z are left between the peripheries of the heads and the cylinder-shell, and the peripheries may be lathenished or not, as desired. The heads h and t' being placed in a proper position within the ends of the cylinder-opening, and with the shaft e located approximately in the center of the cylinder, the parts are secured temporarily in position by wedges or pieces placed between the cylinder-shell and the heads in the spaces Z and Z, and the spaces Z and Z are then filled with a soft-metal bushing, o, usually of lead or Babbitt metal, which is easily melted and poured in the spaces. By means of this bushing o the heads are firmly supported in relation to the shell of the cylinder, and may be removed and replaced again in the same position, the bushing adhering to heads or to the cylinder-shell, as desired, but usually are arranged to remain solid upon and be removed with the heads, and when replaced the uneven and imperfect surfaces of the bushing fit into the uneven and imperfect surfaces of the cylinderopening in the same position as before in relation to the periphery of the cylinder. Vhile the shaft and heads are still in position the cylinder is VIoo placed in a suitable machine and slowly revolved, and the outer faces of the projecting ribs b are ground by a revolving emery-wheel or other suitable means to a true cylindrical form.
On account of the unusual hardness of the material forming the shell of the cylinder great trouble and expense attend the operation of properly balancing the cylinder so that it may be revolved at a high speed, and in order to avoid this difficulty a balance-piece, m, provided with a set-screw, n, is placed upon the end of the shaft in the required position and is properly adjusted and arranged to balance the cylinder when at rest. The parts are then marked, and the nut k is removed and the heads and shaft withdrawn from the shell. The balance-piece m is then placed upon the shaft and firmly secured thereto in a proper position, to be located in the center of the length of the cylinder when the parts are together and in the same angular position as before. A great advantage is gained by placing the balancing-piece m within the cylinder-shell, as it is then so protected that it cannot be easily displaced by accident, and also being located in the center of the cylinder brings the balancing-weight as near as possible to the part or portion of the cylinder containing the overweight, so that the cylinder will revolve more evenly and truly at a high speed. The parts are then put together as marked, and the nut k turned until the parts are drawn firmly together, which finishes the cylinder ready for placing in the machine.
What I claim as my invention, and desire to secure by Letters Patent, is-
l. In a cotton-seed-hulling cylinder, the combination, with the hollow cylindrical shell of hardened or chilled metal and provided with inwardly-beveled end openings, the heads provided with central shaft-openings and with beveled peripheries and passed into the openings in the opposite ends of the cylinder-shell,
with the chamber d, having theinwardly-beveled end portions, c and c', the shaft e, provided with a screw-thread, of the head Insecured to the shaft and provided with a beveled periphery and passed into the one end of the chamber, the removable head ,provided with a beveled periphery and passed into the opposite end of the chamber, the metal bushing o between the heads and cylinder-shell, and the nut la, engaging with the screw-thread, substantially as and for the purpose set forth.
3. Inacotton-seedhulling cylinder, the combination, with a hollow cylindrical shell of hardened or chilled metal, and provided with inwardly-beveled end openings, as described, the cylinderheads provided with central shaft-openings and beveled peripheries and passed into the said end openings of the cylinder, and the soft-metal bushing between the heads and cylinder, of a shaft passed through the heads and cylinder-shell and rigidly secured to one of the heads and having a screwthread extending beyond the opposite head, and a nut upon the shaft and engaging with the said screw-thread, substantially as and for the purpose set forth.
In testimony whereof I aftix my signature in presence of two witnesses.
ABEL D. CATLIN.
