[Ill.u.s.tration: Fig. 67.]
The arrangement at the mechanism is shown in Fig. 67. A hopper-shaded reservoir, made of galvanized iron, is supported by a framework at the back of the seat, which rests on the framework _a_, _a_. Connected with the handle at the right-hand side, there is an iron lever, which operates a movable box at the bottom of the reservoir, and causes it to discharge its contents directly under the seat. When the handle is dropped, the box returns to its position, and is immediately filled preparatory to another use.
The hopper-shaped reservoir is supported by two pivots, and has a slight rocking or vibrating motion imparted to it by each lifting of the lever. This prevents the earth from becoming clogged, and insures its regular delivery.
[Ill.u.s.tration: Fig. 68 THE "PULL-UP" APPARATUS.]
The construction is more clearly shown in Fig. 68.
In this figure, A is the vibrating hopper for holding the earth. Its capacity may be increased to any desired extent by building above it a straight-sized box of any height. It is not unusual, in fixed privies, to make this reservoir large enough to hold a supply for several months.
As the earth is dry, there is no occasion for the use of any thing better than common pine boards in making this addition to the reservoir.
B is one side of the wooden, frame by which the hopper is supported and it may be made of one inch pine or spruce.
C is a box of lacquered or galvanized iron, without either top or bottom. It moves on two pivots, one of winch is shown on its exposed side. In its present position, its upper end opens into the hopper, and its lower end is dosed by the stationary board over which it stands.
When the handle is pulled up, the lever, which is connected with the box, jerks it rapidly up, so that its back side closes the opening of the reservoir, and its bottom opens to the front. In its movement it discharges its contents of earth forward under the seat. When the handle is dropped, the box returns to its natural position, and is charged again.
D is one of the pivots--a corresponding one being on the other side--by which the hopper is supported, and on which it vibrates.
_a_, _a_, _a_, _a_, _a_, _a_, are the parts of the framework, the dimensions of which in feet and inches are given.
The only essential part not shown is an earthen-ware pan without a bottom, similar to the pan of a water-closet, only not so deep and with a larger opening, which is attached to the under side of the seat, and which in a measure prevents the rising of dust, and conducts the urine to the point at which the most earth falls. This is the least important part of the invention, but it has a certain advantage.
The self-acting apparatus is more complicated, and persons wishing it would do best to apply directly to the Company.
THE ORDINARY PRIVY.
In the circular published by the Earth-Closet Company, the following directions are given:
[Ill.u.s.tration: Fig. 69.--Commode, 3 ft. 3 in. high, 1 ft. 11 in. wide, 2 ft. 2 in. deep.]
"An ordinary fixed closet requires the apparatus to be placed at the back of, and in connection with, the usual seat; the reservoir for containing the earth being placed above it. Under it there should be a chamber or vault about four feet by three wide, and of any convenient depth, with a paved or asphalted bottom, and the sides lined with cement. Should there be an existing cesspool, it may be altered to the above dimensions. Into this the deposit and earth fall, and may remain there three, six, or twelve months, and continue perfectly inodorous and innoxious, merely requiring to be occasionally leveled by a rake or hoe. If, however, it should be found impossible or inconvenient to have a vault underneath, a movable trough, of iron or tarred wood, on wheels, may be subst.i.tuted. In this case, it will be advisable to raise the seat somewhat above the floor, to allow the trough to be of sufficient size.
"By one form of construction, (the "pull-up,") the pulling up of a handle releases a sufficient quant.i.ty of the dry earth, which is thrown into the pit or vault, covering the deposit and completely preventing all smell. By another, (the "self-acting,") the same effect is produced by the action of the seat. The apparatus may be placed in, and adapted to, almost any existing closet or privy, and so arranged that the supply and removal of earth may be carried on inside or outside as desired."
The following is taken from the company"s circular:
"In the commode, the apparatus and earth-reservoir are self-contained, and a movable pail takes the place of the chamber or vault above described. This must be emptied as often as necessary, and the contents may be applied to the garden or field, or be allowed to acc.u.mulate in a heap under cover until wanted for use. This acc.u.mulation is inodorous, and rapidly becomes dry. The commode can stand in any convenient place in or out of doors. For use in bedrooms, hospital wards, infirmaries, etc., the commode is invaluable. It is entirely free from those faint, depressing odors common to portable water-closets and night-stools, and through its admission one of the greatest miseries of human life, the foul smells of the sick-room, and one of the most frequent means of communicating infection, may be entirely prevented. It is invariably found that, if any failure takes place, it arises from the earth _not being properly dry_. Too much importance can not be attached to this requirement. The earth-commode will no more act properly without dry earth, than will a water-closet without water.
"These commodes are made in a variety of patterns, from the cottage commode to the more expensive ones in mahogany or oak, and vary in price accordingly. They are made to act either by a handle, as in the ordinary water-closet, or self-acting on rising from the seat. The earth-reservoir is calculated to hold enough for about twenty-five times; and where earth is scarce, or the manure required of extraordinary strength, the product may be dried as many as seven times, and without losing any of its deodorizing properties.
"If care be taken to cast one service of earth into the pail when first placed in the commode, and to have the commonest regard to cleanliness, not the least offensive smell will be perceptible, though the receptacle remain unemptied for weeks. Care must also be taken, that no liquid, but that which they are intended to receive, be thrown into the pails."
The pail used in the commode is made of galvanized iron, and is shaped very much like an ordinary coal-hod. It has a cover of the same material, and it may be carried from an upper floor with no more offensiveness than a hodful of common earth.
Fig. 70 represents a cross-section of the commode, and will enable the reader more clearly to understand the construction and operation of the apparatus.
_a_ is the opening in the seat; _b_, the "pan;" _c_, the pail for receiving the deposit; _d_, the hopper for containing the earth supply; _e_, the box by which the earth is measured, and by which it is thrown into the pail when moved to the position _e"_ by the operation of the "pull-up;" _f_, a door by which the pail is shut in; _g_, the cover of the seat; _h_, the cover of the hopper; _i_ a platform which prevents the escape of earth from _e_.
[Ill.u.s.tration: Fig. 70 HOW TO USE THE EARTH-CLOSET.]
Under this head, the circular issued by the original London company contains the following:
"The first requirement for the proper working of the earth-closet is earth perfectly dry and sifted. Earth alone is proved to be the best deodorizer, and far superior to any disinfectants; but where it is difficult to obtain earth abundantly, sifted ashes, as before stated, may be mixed with, it in proportion of two of earth to one of ashes.
"As the first requirement is _dry earth sifted_, and as this is usually thought to be a great difficulty in the way of the adoption of the dry earth system, the following remarks will at once remove such an impression.
"The earth-commode and closet, if used by six persons daily, will require, on an average, about one hundred weight of earth per week.
This may be dried for family use in a drawer made to fit under the kitchen range, and which may be filled with earth one morning and left until the next. The drawer should reach to within two inches of the bottom bar of the grate. A frame with a handle, covered with fine wire-netting, forming a kind of shovel, should be placed on this drawer; the finer ashes will fall through, mixing with the earth, whilst the cinders will remain on the top, to be, from time to time, thrown on the fire.
"Of course, the most economical method is to provide in the summer-time a winter store of dry earth, which may be kept in an out-house, shed, or other convenient place, just as we lay in a winter store of coals.
"THINGS TO BE OBSERVED
"Let one fall of earth be in the pail before using.
"The earth must be dry and sifted.
"Sand must not be used.
"No "slops" must be thrown down.
"The handle must be pulled up with a jerk, and let fall sharply."
REPEATED USE OF EARTH
Concerning the value and use of the product of the earth-closet, the following is copied from the London company"s circular. (It will be noticed that reference is made, to _the repeated use of the same earth._ When the ordure is completely dried and decomposed, it has not only lost its odor, but it has become, like all decomposed organic matter, an excellent disinfectant, and the fifth or sixth time that the same earth is pa.s.sed through the closet it is fully as effective in destroying odors as it was when used for the first time, and of course each use adds to its value as manure, until it becomes as strong as Peruvian guano, which is now worth seventy-five dollars per ton.
In fact, it may be made so rich that _one hundred pounds will be a good dressing for an acre of land_.)
"If the closet is over a water-tight cesspool or pit, it will require emptying at the end of three or six months. The produce, which will be quite inodorous, should be thrown, together in a heap, sheltered from wet, and occasionally turned over. At the end of a few weeks, it will be dry and fit for use.
"If the receptacle be an iron trough or pail, the contents should be thrown together, re-dried, and used over again, four or five times.
In a few weeks they will be dry and fit for use; the value being increased by repeated action. The condition of the manure should be much the same as that of guano, and fit for drilling."
The inventor of the earth-closet, Rev. Mr. Moule, says:
"It was to this point (the power of earth or clay to absorb the products of the decomposition of manure) but particularly to the _repeated action_, and consequently the repeated use of the same earth, that I first directed the attention of the public. I then pointed out: First. That a very small portion of dry and sifted earth (one and a half pints) is sufficient by covering the deposit, to prevent fermentation, (which so soon sets in whenever water is used,) and the consequent generation and emission of noxious gases. Second. That if within a few hours, or even a few days, the ma.s.s that would be formed by the repeated layers of deposit, be intimately mixed by a coa.r.s.e rake or spade, or by a mixer made for the purpose, then, in five or ten minutes, neither to the eye or sense of smell is any thing perceptible but so much earth.... When about three cart-loads of sifted earth had thus been used for my family, (which averaged fifteen persons,) and left under a shed, I found that the material first employed was sufficiently dried to be used again. This process of alternate mixing and drying was renewed five times, the earth still retaining its absorbent powers apparently unimpaired. Of the visitors taken to the spot, none could guess the nature of the compost, though in some cases the heap which they visited in the afternoon had been turned over that same morning ...
"It is only in towns, where the delivery, stowage, and removal of earth is attended with cost and difficulty, that any artificial aid for drying the compost would be desirable. On premises not cramped for s.p.a.ce, the atmosphere, especially with a gla.s.s roof to the shed, will act sufficiently fast.
"You may by means of it (the earth system) have a privy close to the house and a closet up-stairs, from neither of which shall proceed any offensive smell or any noxious gas. A projection from the back of the cottage, eight feet long and six feet wide, would be amply sufficient for this purpose. The nearer three or four feet down-stairs, would be occupied by the privy, in which, by the seat, would be a receptacle for dry earth. The "soil" and earth would fall into the further five or four feet, which would form the covered and closed shed for mixing and drying. Up-stairs, the arrangement would be much the same, the deposit being made to fall clear of every wall. Through, this closet the removal of noxious and offensive matters in time of sickness, and of slop-buckets, would be immediate and easy; and if the shed below be kept well supplied with earth, all effluvium would be almost immediately checked. As to the trouble which this will cause, a very little experience will convince the cottager that it is less instead of greater, than the women generally go through at present, while the value of the manure will afford an inducement to exertion.
"The truth is, that the machinery is more simple, much less expensive, and far less liable to injury than that of the water-closet. The supply of earth to the house is as easy as that of coals. To the closet it may be supplied more easily than water is supplied by a forcing-pump, and to the commode it can be conveyed just as coal is carried to the chamber. After use, it can be removed in either case by the bucket or box placed under the seat, or from the fixed reservoir, with less offense than that of the ordinary slop-bucket--indeed, (I speak after four years" experience,) with as little offense as is found in the removal of coal-ashes. So that, while servants and others will shrink from novelty and at first imagine difficulties, yet many, to my knowledge, would now vastly prefer the daily removal of the bucket or the soil to either the daily working of a forcing-pump or to being called upon once a year, or once in three years, to a.s.sist in emptying a vault or cesspool."
To the above complete and convincingly apt arguments and statements of fact, we do not care to add any thing. All that we desire is to direct public attention to the admirable qualities of this Earth System, and to suggest that, at least for those living in the country away from the many conveniences of city life, great water power, and mechanical a.s.sistance, the use of it will conduce largely to the economy of families, the health of neighborhoods, and the increasing fertility and prosperity of the country round about.
