DRY CLOSET.

' SPECIFICATION forming part of Letters Patent No. 765,582, dated July 19, 1904..

Application filed October 30, 1902.

To all whom it may concern.-

Be it known that I, FRANK S. LANG, a citizen of the United States, residing at Nome, Second Division, Alaska Territory, have invented a new and useful Dry Closet, of which the following is a specification.

This invention relates to dry closets.

The object of the invention is in a ready, simple, thoroughly feasible and practical manner to obviate the escape of foul odors and to present a-structure that shall be compact in form and neat in appearance and which shall permit of ready removal and replacement of the receptacle when necessary.

With these and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and combination of parts of a dry closet, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, there is illustrated one form of embodiment of the invention capable of carrying the same into practical operation, it being understood that the elements therein exhibited may be varied or changed as to shape, proportion, and exact manner of assemblage without departing from the spirit thereof, and in these drawings Figure 1 is a view in perspective of a dry closet constructed in accordance with the present invention. Fig. 2 is a view in horizontal section. Fig. 3 is a view in vertical longitudinal section with the seat and cover closed. Fig. 4 is a similar view with the seat and cover partly raised.

Referring to the drawings, 1 designates the casing of the structure, the same being con structed, preferably, of galvanized iron and provided with straight sides and back 2 and 3, respectively, and a curved or semicircular front 4. The upper edge of the receptacle is beaded or wired at 4 to impart the requisite rigidity and strength to the structure. Se-

cured to the back are verticalbattens 5, in this instance three in number, to which is secured a cross-piece 6, which constitutes the 5 means of attachment for the hinges 7 of the Serial No. 129,437. (No model.)

seat 8, the latter having hinged to it an ordinary cover 9. Connecting with the rear portion of the casing and preferably at one side (although, if preferred, it may be at the back) is an escape-pipe 10, in this instance shown as provided with an elbow for connection with pipe-joints to be tapped either into the chimney-flue or to be carried without the building, as may be preferred, said pipe to be of a diameter and a height to insure a proper updraft from the receptacle.

The receptacle 11 is of the same shape as the casing, but considerably less in length to present at the rear an air-chamber 12, with which the ventilator-pipe connects. The receptacle is also of less width than the casing in order to provide a ventilating-space 13 between the inner Walls of the casing and the receptacle, as clearly shown in Fig. 2. Said .receptacle is also provided at its upper edge with an annular bead 20, which materially assists in properly spacing the said receptacle from the side and front walls of the casing.

- The receptacle has associated with it in any preferred manner an ordinary bail 14, by which it may be removed When necessary, the casing being provided at its rear with a guide 15, having a downward-inclined upper face, (clearly shown in Figs. 3 and 4,) the function of which is to cause the receptacle always to occupy its proper position with relation to the casing. The back wall of the casing adjacent to its bottom is provided with an orifice 16, said orifice to be of less diameter than that of the ventilator-pipe 10, thereby to set up an induced draft upward through the receptacle and out through the ventilator-pipe, thus to free the casing of all noxious odors.

The upper portion of the rear wall of the receptacle is provided with two escape-openings 17, in this instance shown as elliptical and disposed approximately in line with the intake-mouth of the ventilator-pipe, the induced draft within the air-chamber and out through the ventilator-pipe operating to draw the odors and gases out through the openings 17, thus to render the apparatus positively odorless in use.

The under sideof the seat is provided with astop or staple 18, with which the bail is adapted to be interlocked to hold the seat and cover raised when necessary.

In constructing the apparatus the proportions between the diameters of the ventilatorpipe and orifice 16 will be such that a strong updraft will be formed in the casing and in the ventilator-pipe, thus to render the structure non-objectionable in use, as it will efiectively and positively remove all odors or gases.

Having thus described the invention, What I claim is In a device of the class described, a metallic casing having a straight rear Wall, a plurality of vertically-disposed battens forming spacing members reinforcing said wall,a crosspiece securely connecting the upper ends of said battens, a seat hingedly connected with said cross-piece, a receptacle within the easing, provided at its upper edge with a spacingflange engaging the inner sides of the side and front walls of the casing, a bail connected pivotally with said receptacle and resting normally upon the upper edge of the receptacle beneath the seat, and a hook upon the under side of the latter adapted to be engaged by the bail, when raised, to be thereby sustained in a raised position.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.
