FREDERICK O. HERRICK, OF. CLEVELAND, OHIO.

LA'IRINE FOR USE IN THE FIELD. I

T 0 all whom it may concern:

Be it known that I, FREDERIoK C. HER- RICK, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Iniprovement in Latrines for Use in the Field, of which the following is a specification, the principle of the invention being herein explain'ed and the best modein which I have contemplated applying that principle so as to distinguish it from other inventions.

My invention relates to latrines and particularly to latrines for use in the field by troops in active service.

It is recognized that none of the methods of disposing of dejecta now in use by field troopsis satisfactory. Latrines' now in use are not 'efiicient because they are either unsanitary or if sanitary the labor of construction and the difiiculty of transportation of y the requisites for their construction are such as to preclude their practical use as a part of acamp outfit for active field service.

The object of my invention is to provide a latrine which is both sanitary and of a construction such as to necessitate in its erection a minimum amount of labor and also such as will permit it, and the tools for its construction, to be readily packed in a minimum space and transported in a manner such as to render it practicable for use in active service in the field.

My invention consists of means hereafter fully described and particularly pointed out n the claims.

of my improved construction, a portion being broken away to disclose thelower part thereof. Fig. 2. represent afront elevation "of said upper portion, partly in vertical longitudinal section, showing also vertical sections of the earth in which cavities are formed to constitute .a part of the complete construction. Fig. 3. represents a verticaltransverse section of said upper portion and the earth, taken on a plane passing through Specification of Letters Patent. Application filed October 1 ll9Q6 erialNoh336,8l5-

ing each aperture age t other desired form.

- Patented Dec .,.17, 1907.. I

the axis of one of the cavities. Fig-4; represents a modified form of one ofthe ducts forming a part of my inventidgrand opened out fiat for packing. .Fig il epres'entsa vertical sectional view of a modified form of my invention and Fig. 6. represe ts a plan of the same with the cover partially away.

A rectangular board A, Fig. 2-, preferably of light wood of required strength, is formed with the desired number-of apertures a,

forming seats. This board is preferably re;..

broken to fit into holes bored therein so asto be readily removable. That portion .of ,the board immediately adjacent to the apertures. I shall refer to hereafter as the seat, and the remaining portion of the board and the legs constitute what I shall term the seatsupport? r In the bottom'of the board andsurround which are snugly ted the upper ends of ducts C, so as to be easily removable but at the same time insect-proof, that is capable of preventing absolutely the ingress or egress of insects such as flies, mosquitoesland so forth. These ducts may be made of galvanized iron or cheap stifipaper', card board, papier mach, or veneer the latter materials being shellacked or otherwise treated to renformed grooves a} into der them water proof. The du cts as illustrated are frusto-conicalbut may, ifgfound preferable, be made cylindrical or pf any conical or pyramidal in shape they may be nested for transportation. If desired they.

When made frustoe screws or nails may be drivento hold the ducts securely in place in their grooves. It will thus be seen that flies and other insects are effectively excluded from the receptacle j and its contents. To further insure a tight '5 {oint between the excavation and the duct, oose earth may .be banked and packed around the exterior as shown in the righthand portion'of Fig. 2. As shown in Fig. 3. the ducts have a trend or inclination from the top portion rearwardly, whereby they are given apos tion in which the walls are as nearly as possible parallel with the path of the dejecta and the amount of the latter projected upon and adhering to such. walls thereby reduced to a In 5.". I have illustrated a modified form of atrine in which but a single aperture 1s rovid'ed. Theseat-support D consists of a rlngd to the lower side of which are removably secured the legs 01'. The duct (1 is made with a flange d which fits over the upper surface of the ring, .and in a depression (1* formed therein. The said flange forms the seat-proper. A suitable spring-actuated cover is-provided to ,closethe .top of the duct, as shown.

In either of the above illustrated constructions it will be seen that the parts of the seatsupports are readily dismounted and packed so as to be easily portable. When the ducts 'are made of sheet metal they are washed. and sterilized after use, by burning out or by means of suitable chemical sterilizing agents. When made of combustible material they are preferably com letely destroyed by burning or they may i; the excavations. formed by means of the ordinary clam-shell or auger post-hole dig ers which are easily 40 acked and transportec l in a small com ass. en the latrine is to be aband'one the parts of the seat-supports are dismounted,

cleansed and sterilized, the ducts removed, cleansed and sterilized or destroyed and the excavations filled up.

By means of my above described arrangewent I obtain a latrine having all of the neces sary requirements of sanitation,portability, cheapness, which requires in its. construction a minimum of labor'and such labor is performed with the aid of tools readily andeasily packed.

Other modes of applying the rinciple of my invention, may be employed instead of the one explained, and changes may be made in the construction herein described provided the means stated in the following claims or the equivalent of said stated means be employed.

I therefore particularly point out and (118- tinctly claim as my invention 1. In a latrine, the combination'of a portable structure formed with a suitable seataperture, a duct suspended from said struce crushed and buried in The saldexcavations are for keeping said cover normally in a ture, and a receptacle formed by drilling an excavation in the soil, the lower end of said duct pro ecting mto said receptacle, said duct presenting at all times an unobstructed passage from said aperture to said recep 2;. In a latrine, the combination of a portable structure formed with a suitable seat-- aperture, a receptacle below said structure, and a duct detachably suspended from said structure, said duct presenting at all times an unobstructed passage from said aperture to said receptacle.

3. In a latrine, the combination of a structure provided with a suitable seat-aperture, a duct suspended and readily removable from; said structure, and a receptacle, the lowerend of said duct projecting into said receptacle. 4. In a latrine, the combination of a seat .and seat-support forming a portable structure, a receptacle formed in the soil below said structure, and a duct detachably secured to the lower side of said structure and having its lower end projecting into said receptacle.
