REDUCTION SYSTEM.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed June 27, 1910. Serial No. 569,032.

To all whom it may concern;

Be it known that I, ALBERT J. Monmok,

a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved ReductionSystem, of which the folpeople living in the vicinity.

lowing is a full, clear, and exact description.

My invention relates to reduction systems used for cooking, reducing and converting garbage, ofi'al, slaughter house tankage, dead. animals and fish, and materials of various kinds, for the double purpose of ridding communities of the various objectionable materials mentioned and of making various products and by-products by workin up the same.

y present invention is assoc1ated.more or less remotely with that described in my Patent No. 931,457, of August 17, 1909, for a separator, some of the parts in my present invention being similar to parts described in my said patent.

Among the objects which I seek to accomplish by my present invention are the following: I. To provided for saving greases and oils which may accumulate from time to time in the reduction tank under conditions where ordinarily these materials might be wasted. II. To prevent undue liberation of noxious gases and vapors to the detriment of health and comfort of III. To so connect up a number of presses with pressure tanks that a single pressure tank may be used to fill two presses, thereby enabling the presses to be made smaller than would otherwise be necessary. "IV. To improi e the general efficiency of reduction systems by improving the construction and action of various parts used in connection therewith.

Reference is to be had to the accompany ing drawings formin apart of this specification, in which similar characters of re't'en once indicate corresponding parts in both the figures.

Figure 1 is a fragmentary elevation showing my improved reduction system; and Fig. 2 is a detail showing one of the presses and the pressure tank immediately connected therewith, this view further showing the by-pass for dividing the contents of either pressure tank so as to fill two presses of smaller size.

A framework 3 supports conveyor mechanism 4, the latter including rollers 5, 6. At 7 is a platform associated with the cor.- veyer mechanism, and at 8 is a swiveled chute supported by the platform 7 for the purpose of transferring materials from the lat ter. The parts just enumerated being old and well-known, need no further description. The framework 3 includes large sup porting beams 9 disposed horizontally.

At 10, 11 are reduction tanks, the tanks being provided with lugs 12 which engage the horizontal beams S).

At 13, 1.4 are pressure tanks and below these are the presses 1.5, 16, these presses being substantially of the kind described in my Patent No. 931,457, referred to above.

At 17 is a by-pnss connecting the two pressure tanks 13, let directly together. This by-pass is controllable by a hand valve 17 (see Fig. 2) and by aid of said valve may be opened and closed at the will of the operator. Steam pipes are shown at 18, 19 and are fed with live steam from a supply pipe 20. The pipes 18, 19 are provided with hand valves 21, 22. by aid whereof steam may be thrown into either pipe 18 or 19, or into both, as desired.'

At 23, 24 are hand valves for opening and closing couununication between the pressure tank 14 and the prcssslti. Steam pipe v 25, 26 are c'ormccted respectively with the bottom of the reduction tank 11 and top of the pressure tank 14, and are controllablc by hand valves 27, 28, the steam 'bcing supplied to the pipes 536 through the supply pipe 29. Each press 1.6 is provided at its bottom with a swinging door 30, this door carrying an outlet pipe 3t. The door also carries a "fork 32 in which is a roller 33 running upon a circular track 34: and supporting the weight of the door 30 together with such pressure as may be exerted on said door. A steam pip 35 is connected with the reduction tanks 1.1, 10 by pipes 36, 37. At. 38 is a trap which is also connected with the pipe 35. A pipe 39 leads from the trap 38 to a condenser 10, the latter being controllable by a band valve 41 and being provided with an outlet pipe 42. Connected with the bottom of the tra i 38 is a discharge pipe 43 which extents downwardly and is provided with a hand valve 44 whereby it may be opened and closed.

At 45 are platforms and mounted upon the same are railings 46 for the convenience of the operator.

At 47 is a conveyer belt which runs upon pulleys or rollers 48 and is used more particularly in connection with emptying the presses 15, 16.

At 49 is a pipe leading to a condenser 50, the latter being controllable byaid of a hand valve 51.

Extending from't-he pipe 49 to the pressure tanks 13, 14-are pipes 52, 53. These pipes are provided with hand valves 54, 55.

house tankage, and the 1i 11. For this purposethe hand valve 57 is previously closed. -The reduction-tank lo may, it desired, be filled in the same man ner. The tops of the reduction tanks being closed-tight, steam is now admitted through I the pipes and the materials contained in lthe reduction tanks are thus heated and' cooked. Suppose, now, that owing to splashing takin place in the reduction tanks 10, 11', cause by accidental irregularities in heating or lack of homogeneity in the mate- :rial operated upon, it should happen that the portions of solid matter are driven upward throughthe pipes 36, 37. These ortions of solid matter are driven a ong through the pipe andin'to the trap38, It happens that the "greases and oils from the material nearly always float on top of the materials, and thus being uppermost they are liable to be forced upward through the pipes 36, 37. If this happens, greases and oils are taken into the trap 38 along with the solid matter, and as this trap is partially filled with water 113011 which the greases and oil float, the atter may be readily tapped oil'at any time by aid of the discharge pipe 43 and the hand valve 44. All

steam, vapors and gases, including such vapors and gases as are noxious or possibly oisonous, are free to pass up-' wardly romthe trap 33 and through the pipe 39 to the condenser 40 where they.

- are, as far as practicable, condensed and discharged in liquid. "form through the outlet pipe 42. In the trap 38 the lower end of the pipe 35 normally dips below the level of the liquid. contained therein, though this isnot by any means "necessary. The materials being completely cooked and reduced in the reduction tanks 10, 11, are next trans- ,ferred downwardly through the pressure tanks. This. is done by opening the valves 56, 57a The pressure tanks being'thus filled, the valves 56, 57 are closed and steam is adeeaoar mitted throughthepipefliiby aid or the hand valves 21. If at, any time an overflow takes lace from the pressure tanks 13, 14, or if or any reason greases, solid matter or other portions of the materials operated upon arethr'own upwardly through the pipes 52, 53, they pass into the pipe 49 and along with steam and various vapors and gases are carried to the condenser 50, being rendered, by action of the condenser, as harmless and, as compact as possible. This en- 'ables'these materials to be saved, in so far as they may be Worth saving. If need be, live" steam may be supplied. to the pipe 18 and the materials cooked still furtherin the pressure tanks.- The stirring of the materi als,'d ue' to their transfer from the reduction tanks down'int-o the pressure tanks, frequently places them in a'condition to be cooked further by the application of fresh steam.: The process being practicallyfin ished, the next step is to run the converted materials from the pressure tanks 13, 14 into the presses 15, 16. To do this the valves "56, 57 .aremclosed, and the valvesi23, -24 of either of'the presses are next opened. Steam being now admitted throughthepipe 26, the materials are forced downward by steam pressure, so as to fill one ofthe presses. The by-pass 17 being opened byaid of, the valve 17 (se*e Fig. 2) a portion of the, materials is" forced through 'the'pipes into the opposite'pressure tank'if this tank happens to be otherwise empty or happens to be sp'acious enough to receive the material.

Under ordinary circumstances, if the apparatus be used in connection with ,full

charges of the material, each charge when thoroughly cooked and reduced is just about sufl'icient to fill the two presses. The. pres-' sure tanks 13, 14 are emptied alternately" and if there be a large number ofthese tanks they are arranged in pairs, the two tanks of I each pair being alternated in their action of discharging into the two presses. Any umber of the pressure tanks 13, 14 maybe sed simultaneously up to the moment of discharging their contents into the press,|but

in discharging their contents the'pres ure tanks are operated one at a time.

In some instances I rials into only one .o 10, Y11 and when the reduction is com lete,

refer to fill the niate: l the reduction t nks to transfer these materials straight d wnward into the pressure tank below and cor responding to the reduction tank thus lsed.

The difference in size'of a reduction ank and its corresponding pressure tank represents theapproximate shrinkage ofth material, due to its. cookingand to variouslosses which always take place during this operation. Whereonly one: of the cooking tanks 13 is full orapproxiinately full {of the reduced material, there is economy in using both-ofthe presses 15, 16, and this done by aid of the by-pass 17, as above described. That is to say, by using one pressure tank 13 or 14 and filling the two presses 15, 16, the work is done as rapidly as would be the case if the pressure tank in questionwere used with a single press of larger capacity. It is obvious that if a single pressure tank (13 or 14:) can thus be used with both of the presses'15 and 16, and these presses can consequently be made smaller than would otherwise be necessary-to wit, just half the capacity-the s stem as a whole is cheap- .ened by the di erence in thecost of large and small resses, and as these presses are usually quite expensive, thesaving is considerable. Moreover, it frequently happens that in plants of this kind there is a scarcity of room and especially of room extending vert-ically upward. By having the presses 15, '16 comparatively small, as above described, the available space is conserved in every sense, and even the building in which the plant is located may, if desired, be rendered slightly loWer-other things being equal0wing-to the reduction in size of the presses. The materials being forced downwardly into the presses, the action inside of the presses, and subsequently to their filling, is substantially the same as that described in my patent above mentioned. .The materials and products extracted therefrom are removed from the presses in the'manner already known in this art and described in my existing patent.

While I show the various reduction and pressure tanks as cylindrical, it will be understood that I do not limit myself thereby,

terials mentioned, around large cities where they accumulate and must necessarily be dis;

posed of in some suitable manner. Byaid of the system above described the materials may be disposed of at considerable advantage, the various products and by-products being oftentimes of considerable value.

Having'thus described my invention, 1'

claim as new and desire to secure by Let'- tersr Patent a 1. The combination ofva plurality of pressure tanks, a bypass connecting the same together, a separate press connected with each of said pressure tanks, and means for applying pressure to materials contained within one of said pressure tanks for the purpose of causing a portion of said materials to pass across from one pressure tank to another in order to fillall of the presses. 2. In a reduction system, the combination of a plurality of pressure tanks, a plurality of presses each connected with one of said pressure tanks, valves dis osed between said pressure tanks, and a y-pass extending from one of said )ressure tanks to another. In testimony w ereof I have signed my name to this specification in the presence of two subscribing witnesses.
