SPECIFICATION forming part of Letters Patent No. 447,808, dated March 10, 1891.
Application filed February 15, 1890 Serial No. 340,5t6. (N0 model.)
To all whom it may concern.-
Be it known that I, PHILIPP G. CLOSE, a citizen of the United States, residing at Augusta, in the county of Richmond, State of Georgia, have invented certain new and useful Improvements in Grinding, Drying, and Incorporating Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to that class of machines in which the material-containing cylinder is adapted to be revolved; and the 0b- 3' ects of my improvement are to provide a simple machine'adapted to operate upon either dry or wet material, particularly fertilizers, and to be heated either by steam or by the product of combustion from the furnace of the boiler furnishing power to operate the machine or from a furnace attached to the side of the incorporator. I attain these objects by-the construction illustrated in the accompanying drawings, in Which- Figure 1 is a longitudinal vertical section of a machine constructed in accordance with my invention. Fig. 2 is a plan of the same with the top of the apparatus and also the incorporating cylinder removed. Fig. 3 is a top view of one end of the apparatus with the incorporating-cylinder in section. Fig. A is an elevation of the discharge-opening of the apparatus. Fig. 5 is a front perspective view of the apparatus with the hopper and part of the gearing removed. Fig. 6 represents in section and side view, on an enlarged scale, one of the balls used in the incorporating. Fig. 7 represents a vertical section of the apparatus on line y 3 of Fig. 2, and Fig. 8 represents a longitudinal section of a modified form of cylinder and pulverizers.
In said drawings, A represents a cylinder or casing, either plain or corrugated, within which are placed a series of balls B, of castiron or steel, of suitable weight to pulverize the material introduced into the casing. The halls placed within the casing adjacent to its feeding end may be provided with a rough surface, as shown in Fig. 6, and if a plain cylinder is used for a casing the balls or internal grinders may be elongated in the form of short cylinders, as shown in Fig. 8. The casing is preferably provided with transverse partitions a between the balls, and said par-' titions have a large opening in the center, and the edge of said partition is preferably serrated or scalloped, as shown in Fig. t, so that if long substances-as straw or the stalks of plants-are fed into the cylinder and the latter is revolved they will be out into small lengths and disintegrated by the balls rolling over them while a portion of their length is in engagement with the serrations.
The revolving casing or cylinder A is slightly tapering, being wider at its discharge end to prevent clogging of the material therein, and also to facilitate its advance therein as the bottom is thereby inclined, although the axis is preferably horizontal.
The cylinder A is provided at its discharge end with a cylinder H, of fine Wire-cloth, to separate the finely-ground product from the coarser part. Said fine product, after passing through the meshes of the Wire-cloth, falls against the sides of a funnel G, and, escaping from the slot gin its lower end, falls into the chamber G while the coarser portion escapes through the openend of the Wire cylinder H and falls into the chamber G in the bottom of which a conveyor G is placed to conduct the material out of said chamber.
The cylinder A is carried by pairs of fric tion-rollers 1 having their shafts mounted in bearings I at suitable points under said cylinder, said bearings being mounted on the foundation E, made preferably of bricks. To revolve the cylinder A, there is secured upon the feeding-in end thereof a cog-wheel W, which meshes with a pinion V on the under side thereof, said pinion being secured upon the driving-shaft A, said shaft carrying the driving-pulleyA to which motion may be transmitted by a belt from a suitable power. Upon the shaft A is also mounted a pinion A that meshes with a large cog-wheel A upon the shaft of the worm or feeding-screw N, that feeds the product that is to be ground into the revolving case A. The outer end of the worm-shaft is carried by the stand A To make close joint between the brick arch or inclosure around the cylinder A and the driving-gear WV, a cast-iron ring 0 is set in the arch back of said driving-gear.
The cylinder A is so incased that its contents can be subjected to a higher temperature than the surrounding atmosphere while IOC being pulverized by means of a fire placed upon the grate-bars B of a furnace B located alongside of the apparatus, preferably adjacent to the feed end of the cylinder, and provided with the necessary feeding-opening S and draft-openings T and U. The products of combustion can be made to pass entirely around the cylinder A to points adjacent to its discharge end, at which points they take, under the impulse of the draft in the chimney P, a downward course through the flue B into the return arch-flue-F and along said arch to the opening f, which communicates with the uptake-flue of the chimney, the draft of which is controlled by a valve or damper f in said chimney. A portion of the products of combustion can also be made to pass through a portion of the cylinder A and its contents. For this purpose the passage D between the cylinder and its inclosing arch and walls E is provided with Valves or dampers d, which can be pushed across the passage D until nearly in contact with the cylinder. Nearly the whole of the products of combustion will then pass through two fines D at the front end of the passage D, Fig. 3. Said fines are bent inwardly to ward the axis of the apparatus and lead the products of combustion into the cylinder A between the discharge end of the hopper M and the inner surface of the cylinder, and said hopper being kept full and practically closed they follow the interior of said cylinder and escape through the meshes of the wire-cloth separater H into the inclosing funnel G, and thence take a downward course through the flue B and the return arch-flue F in the chimney.
The pulverizer shown in Fig. 8 has a plain cylinder A, which can be provided with a screen at one end and an inclosing arch, as shown in Fig. 1; but the balls are retained in proper relative position by being linked together and chained or loosely bolted to posts or stationary standards T Having now fully described my invention, I claim- 1. The combination of a hollow cylinder and balls therein and a hopper at one end, an inclosure around said cylinder, a furnace alongside of said inclosure, smoke-passage be tween said inclosure and the cylinder, downward fines B adjacent to the discharge end of the cylinder, the chimney P, and the arch F between the downward flue and the chimney, substantially as described.
2. The combination of a hollow cylinder and balls therein, an inclosure around said cylinder, a furnace, a smoke-passage between said inclosure and the cylinder, valves d in said passage, and pipes D leading into the entrance of the cylinder, substantially as described.
3. The combination of a hollow cylinder and balls therein, a screen H at one end of said cylinder, and a chamber with a conveyer therein beyond said screen, with a furnace, and passages D and D leading into the cylinder, substantially as described.
In testimony whereof Iaffix my signature in presence of two witnesses.
PHILIPP C. CLOSE.
