APPARATUS FOR REDUCING MATERIAL TO A PULVERULE NT' FERTILIZER.
sPEoIFIoA'rIoN forming art of Letters Patent ma a, dated March 21, 1882.
' 7 Application filed November 8, 1881; (No model.)
- from dead carcasses, hair, &c.
Among important objects attained by my invention over other methods heretofore employed are great simplification and cheapne'ss of the apparatus; a very material reduction both in the time and in the cost of treating and preparing for market, amounting, itis believed, to at least fifty per cent. an important increase in the commercial value of the product; the completion of the process at a single continuous operation, thus obviating --in mechanical association with a system of rothe necessity of subsequent sifting or grinding or of rehandling of the product-a matter of great importance both in a sanitary and commercial point of view.
The-useful novelties com prise a new and useful construction and arrangement of disintegrating and comminutin g or grinding devices;
tat-ing disintegrating-blades, a special form of dischargin g-orifices to prevent balling of the 'material; a condensing arrangement for creating a partial vacuum in the grindingcylinw der, in connection with a utilization of the heat an axial section of an apparatus embodying my invention. Fig. 2 is a transverse section of the cylinder, the discharge-apertures being shown "closed. Figs. 3 and 4 represent to a larger scale portions of the disintegrating mechanism with the discharge-apertures open Fig. 3 being a section in the plane of revolution, and Fig. 4 a section in the plane of the grinding-shaft. V
The apparatus consists essentially of a horizontal cylinder, A, that may be wholly, but is preferably only partially, steam-jacketed, B. This cylinder may be of any suitable material, but is preferably of steel or mild steel, the outer concentric sheet inclosing the steamjacket B being preferably of iron. By the use of steel or semi-steel for the cylinder proper I secure a much better radiating-surface for the heat with increased strength of material, and (whatis also very important) the material under treatmentis much less apt to adhere tothe walls of a steel cylinder than it is to those of an iron one. The jacketpreferablyincloses thecylinder proper for three-fourths of its circuit, leaving the top unjacketed, as shown in Fig. 2. The heads 0 of the cylinder have suitable stuffingboxes, D,fora shaft, E, which may be solid, but is preferably hollow for the reception of heated air or other heating agent to assist, when new essary, in warming-the interior of the cylinder. To this shaft are attached arms F, composed of steel or mild steel, braced by stays G, as shown in Figs. 2 and 3, said arms being thin and being sharp at their advancing edgesf, and being armed with steel knives or blades H, also thin and sharp at their advancing edges, operate to cut through and disintegrate the mass, instead of lifting it bodily. The shaft E is preferably revolved by a belted pulley at some part of its driving-gear, in order that the driving mechanism shall be capable of giving way before breakage of the machinery in the event of the accidental entrance of such refractory bodies asrocks, raw bones,fragments ofiron,or broken bottles.
J represents filling-holes, closed by manheads or covers J.
I arrange in thebottom or under side of the cylinderone or more longand narrow discharging-holes, K K, with abruptly-angular edges. The longitudinal direction of these holesis parallel withthat of the cylinder, and that one of the longitudinal edges which is opposed to the action of the knives is preferably notched, toothed, or serrated, as at M or M. The closing-plates L fit within these holes, and their top surfaces, when the'said plates are in place,
- are preferably about two incheslower'than the cylinder-floor, so as to form thereby a sink or depression, whose effect is to catch and retain agglomerated masses, lumps, or balls of the material, which the knives are thus enabled to cut through and break apart so as to prevent balling and to produce the finely-granulated condition desired. Thiseffectivecomminntion, operating simultaneously and coactively with the desiccating agencies, results in quickly and without detriment to the useful properties of the ingredients reducing the material to the proper pulverulent or granular form.
The cavities formed by the discharge-holes and the closing-plates serve as gathering or lodging places for such smallaud hard objects as gravel-stones, nails, and the like, which are thus detained until the proeessis finished, doing no harm, and are discharged in the act of emptying the machine.
The described form of discharging-hole, in conjunction with the revolving system of agitating-blades, enables the machine to be emptied in two minutes time-an important consideration both sanitarily and economically.
Practice demonstrates the importance of ability to bring the edges ot'the comminutingknives as nearly as possible in contact with the interior surfaces of the cylinder without detrimental, because the spring causes the scraper to touch the cylinderside and to press upon itwith more orless force, which increases the resistance proportionally, and consequently subjects the machinery toa serious amount of additional strain, and adds to the expense for more power to drive the mill. Furthermore, the spring-scraper does not always prevent material adhering to the sides of the cylinder, where it is apt to bake and harden so quickly that no spring that is practically available can enable the knife to scrape ofi' the incrusted matter, and consequently the scraper yields and passes over it, so as to rapidly accumulate a hard packed and tenacious enamel, where, from constant exposure to the heated plate, it seorches, and in so doing loses its most valuable properties, at the same time giving out a penetrating empyreumatic odor. This evil is substantially avoided in the action of my device, because the knives, being absolutely unyielding, prevent any serious accumulation of material on the cylinder-walls.
In order that the presentation of the knives may be capable of adjustment for any desired angle and proximity to the cylinder, according to the nature of the material to be operated upon and the purpose for which it isintended, and to enable the knives to be set up from time to time or removed for sharpening or substitution, I attach them to their arms-in the manner following Each knifeH consists preferably of a wide chisel-formed blade, riveted or bolted fast to helves N N, of which each is pivot-bolted to its arms F. Each hclve terminates in a serrated segmental edge, a, concentric with the pivot O, to which fits a removable similarly-serrated key, P, which, after the knife has been brought to its desired adjustment, is secured in place by a locked bolt, Q, and by the confining-lugf upon the arm F.
For additional security the helve may have a slot, it, also concentric with pivot O, for a bolt, R, by which the helve is clamped fast to the arm.
To facilitate discharge the closingplate L of each ventage is swung upon a central bolt, S, which, depending from a bridge, 7., at the mid-length ot' the aperture, passes through the center of the plate, below which it carries a nut, T, by which the plate'is held to its closed position, and which, being turned down, permits the plate to descend and he swung to a position parallel to and immediately underneath the bridge k, as shown in Figs. 3 and 4, so as to be entirely clear of the escaping contents.
U represents a pipe by which steam is conveyed to jacket B from a boiler, V.
X is a pipe through which the vapor evolved in the cylinder is conducted to a condenser of anysuitable form. Theform of condenser pret'erred by me consists of a receiving-chamber, Y, that connects with a discharging-chamber, Z, through acongeries of tubes, 2, surrounded by cold water contained in a tank, 3, which is supplied by a cold-water pipe, 4,and overflows through'a pipe, 5, into a hot-water tank, 6, from which a pipe, 7, passes to the boiler-feed pump. The cylinder vapor-pipe X connects with the receiving-chamber Y. From the discharging-chamber Z a second vapor-pipe, 8, leads to the boiler-furnace 9, where the residue of uncondensed mephitic emanations from cylinder are consumed and rendered innocuous.
In order to expedite to any desired extent the discharge of noxious effluvia and at the same time consume the same, and by the same means aid the combustion in the boiler-furnace or a special furnace, I provide in a convenient part of the pipe 8 a blower, 10. The rarefaction or partial vacuum produced thereby in the comminutingcylinder enables the desired evaporation to take place with a moderate degree of heat, and consequently with a complete saving of the valuable ammoniacal bases.
A pipe, 11, conducts the water of condensation of the steam-jacket B into the hot-water tank 6.
12 12 represent removable sliding ends or shutters located at the extremities of the con denser, whose elevation or removal enables the interior portions of the condenser-such as the tubes 2 and the chambers Y Z-to be inspected and cleansed at any moment with facility and dispatch. The water of condensation of the chamber Z escapes through a suitable drainpipe, 13. i
The above-described preferred form of my ICC improvement may be varied in non-essential particulars-for example, a grating flush with the floor of the cylinder may in some cases be substituted for the described open months of the discharge-apertures.
I claim as new and of'my invention- 1. In a desiccator and mill for the purpose designated, the combination, with cylinder A, of disintegrating-arms F and knives H, both formed of thin plates of steel or mild steel set edgewise in direction of rotation and made sharp on their advancing edges, as shown and described.
