'SPECIFICATION forming parc of Letters Patent' No.' ns1 ,i samenle-'gust 1e, 1892'.- f Appumion'sna December 13,1890. sen'n no. 374,642. da mobiel.) l f 4To all whom it may concern 'Be it known that I,JOHN S. RSH, a citizen A of .the United States of America, residing at Denver,in the county of Arapahoe andvStatek of Colorado, have invented certain new and useful Improvements in Dry Closets; and Ido" declare the following to be a full,"clear, and

f exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make anduse-the same, reference being-had-to the accompanying drawings, and' lto the: figures of reference marked t ereon which form a part of this specification.

My lnvention relates to improvements in dry closets in which the liquors are separated from the solid residue and 'carried to evaporating-pans, whence the vapors therefrom are' taken up in a suitable lueby the ascending products of combustion, while the residue is removed from timeto time; and it consists in" the construction, arrangement, and combination. of the parts of which ii; is composed, as'

' vwill be hereinafter more fully described and claimed.

Referring to theaccompanyin'g drawings, in which corresponding parts `are'designated by corresponding numerals, Figure 1 is aplan Aview of a closet constructed in accordance with my invention', portions ofthe' several plates thereof being broken away. Fig. 2

is an elevation thereof, parts of the front wall being broken away. Fig. 3 is atransverse section on line ct bof Figs. l and 2. Fig.

\4. is a detail of the plate forming the bottom o f the` upper compartment. Fig.5 is a transverse section on line c cl of Fig.'1. Fig. 6 is a .longitudinal section of a closet in which a modified form of the evaporator is used. Fig.

7 Vshows a modified form of smoke and urine trough.,

The closet consists of a vault'structure upon which maybe erected a suitable 'form of superstructure, (not f shown,) the vault structure having at one end thereof a flue or Stack 3, which is-separated from the lower portion of the vault by ineans of the transverse Wall 4, while al second transverse wall,

A v5' of -a little greater-height is constructed within the vault between the said wall .4 and 5o the opposite end wall 6 oft-he vault, which 'openings may be formed the plate. v Aopposite end of the plate 9 between the wail ture1(l), whence, thesaid end is led'iorward onone side'of the .opening to nearthe front:l thereof, where it passes `under a'pulley 22, se

.covering of the' vault, that portion of the said plate between the stack and the transverse Wall 5 being provided with seat-apertures 10, provided with the vrear,wardlyhinged covers A-11. In `the'annexed drawings I .have shown `but one of'the said seat-openings; but it is evident thatany desired numbe'rof such seat- In the 5 and the end wall 6 an aperture'lZ is formed, it being covered by a lidl, the said aperture giving yaccess "to the evaporating-pan.

Below the plates 9 and above the top'of the walls 4 and 5 a second plate 13 is huilt into the wall,eXtending from end to end.` and side to Side thereof, the said plate 13 sloping sli'giftlyfom front to r ,a,r, and h'ereina-fterI4 will designate the vault space inclosed by the plates 9 and 13 the upper compartment.V An

ssl

aperture 14 is formed in the plate 13 beneath the seat-aperture 10 in the plate 9, the aperture having-its upper end surrounded by a beading 1,5, which flares toward the front, a

curved platelG being inserted between the ared ends-of the beading, while a cover 20 is adapted to turn down over the'said aperture 14, it being hingedat 'its rear end to the plate 13in the rear o f the said aperture.' The lower end' of a cord lssecured to the forward end of the cover 2O and passesrearwardly upward and around pulleys 21, set i'n the, top plate 9 in they rear of the `seat-apercured to the plate-9, and has its upper end secured to the forward portion of the lid 11. It will thus be seen on raisingv the`lid11 that the .lid 20 will be also raised. A rod'.24 pro-. jectsl from t-he rear wall-of the vault and serves to carry a helical vspring `Zai-,tile for- Award end of which projects a suilieient distance toward the front of. the vault .to bear upon the lid 20 whenthelatter is raised, the

Ksaid spring tending to throw the said lid 20 down and thus to c1ose. the upper lid 11, which will be done immediately upon the pressure roo ofthe body being removed Vfrom the lid 11. An aperture 26 is found in the plate 13 beneath the aperture 12 in the plate 9, the said aperture 26 being provided with a lid 27 and beingimmediately above the aperture 27 (provided with the lid 28) in the topof the furnace 29.

' As will be seen from Figs. 1, 2, and 5 of the drawings, the furnace 29 is composed ofany suitable material and is built within the vault it being in the forward portion of the latter v lines in Fig. 2,) also set in the front vault wall,

the end wall 33 of the-furnace being apertured at 34 for the admission of air directly to the combustion-chamber from the end of the vault below the plate '13, to which the air is admitted by the'aperture 35 in' the end wall 6. A defiector 36 projects inwardly fromthe end wall 33 of the furnace above the opening 34 to near 'the opposite wall thereof, while an evaporating-pan 37 projects from the said opposite wall of the furnace to near the said wall 33, the said pan being slightly above the plate 36, and it will thus be seen that the products ofv combustion to reach the smoke-trough (to be hereinafterdescribed) will be compelled to pass ,beneath and over the said pan 37,*thus evaporating the contents thereof. Oppositely '-disposed ledges 40 are placed upon the transverse wall 5 and the end wall 4 at about the level of the top of the furnace, upon which ledges a trough or pan 41,

provided with engaging lips 42 upon its ends, is adapted to slide, the front wall of the vault being provided with a door 43,through which the pan may be withdrawn when it is desired to remove the solid residue. From the abovedescribed location of the pan it will be seen that it is beneath the seat aperture or apertures 10, and that it is adapted to receive the deposits therefrom after they have passed through the aperture or apertures 14. The center of the trough or pan 41, which is at its lowest point, is perforated, as at 44, to permit the passage of liquids, the perforations being in line and over the combined smoke and urine trough 45. This trough 46, into which the liquids fall, extends from the furnace to the flue 3, it entering the former above the evaporating-pan 37, vto which it is adapted to conduct the liquids when given the proper inclination. In the drawings two forms of troughs are shown, the one shown in Fig. 3 having two separate conduits, thelower covered one 45 for the smoke and the upper uncovered one 45" for the urine, the two being separated by the partition 45c, while iu Fig. 7 a form is shown in which the two conduits are united in one, the trough 41 being formed without the partition. may be desired to change the point of evaporation from the furnace to the base of the As in some cases it stack or flue, at which latter point any de- 7o '-rator in the base of flue, (for which a spout 53 may be fitted to the trough,) while if it rests upon one of the cranks of the enlargement, as shown in Fig. 2, the urine will flow into the evaporating-pan in the furnace.

In order to furnish that portion of the vault which is below the pan 41 and .between the walls 4 and 5 with air, a plate 55 is placed within the vault near the bottom thereof and between the rear wall of the furnace and the vault, thus forming a passage 56, connecting.

` at its opposite ends with the apertures 57 and 58, in the base of the transverse wall 5 and the end wall 6, respectively.

In Fig. 6 a form is shown in which the sole evaporator 60 is located in the base of the flue, the urine-trough being given the proper inclination for the flow of urine to take place in. that direction only, and a spout 53L is placed upon the -lower end of the trough to convey the urine into the said evaporator. In this figure the furnace is shown without the evaporating-pan, a deflector 36" being used, however, and, as will be noticed, both the evaporator 60'* and furnace are shown to be heated with gas.

The operation of the invention may be summarized -as follows: The lid or cover 11 having been raised, raises with it the under lid 20, and matter may then drop through the two apertures 10 and 14 in the two plates 9 and 13 into the 'pan 41, through the perforations in which the liquor drains in the urinetrough, and thus tothe evaporating-pan in the former or the base of the stack, as the case may be, the direction of the flow in the, construction shown in Figs. 1 to 5 being dependent upon the position of the bar 49, as has already, been described, the position of the said bar being readily changed'by means of the handle 57 to suit the 'choice of the op erator. In any case the. urine is in its passage through the trough more or less evaporated, thus reducing to a minimum the amount lof work to be done .by the evaporatiug-pans,

while at the same time the solids left inthe pan 41 are dried by the heat arising from the' trough, and are thus when the pan is removed from the vault to be emptied in a state in which they can be the most readily handled. It will also be seen that the constant draft up the flue or stack will keep the air in .all
