    Falilman^s Improved System of Disinfecting Foecal Hatter. bottom of tlie plate there is a projecting arm or lever H, above which there is a projection on the rod G, having a head screwed on the top, the head being in contact with a hinged seat. The weight of the person occupying the seat causes the plate P to be vertical by means of the 5 rod G and arm H, and then the vessel A and box B are in proper positions for receiving the urine, but when the person rises the weight of the vessel A and box B causes them to turn over and empty the contents of the box into the receptacle E, the urine mixed with disin¬ fecting matter being effectually spread over the excrement. 10 Eig. 4 is a front view of the plate and bracket E, E^; Eig. 5, a side view of the plate E with its arm H and the rod G, there being also side and top views of the guides and stops; Eig. G is a front view of the vessel A and box C ; Eigs. 7 and 8 are top and side views of the vessel A, and Eigs. 9, 10, and 11 are bottom, top, and back views of the box 0. 15 The apparatus can be made of lead, tin plate, or other suitable metal, or of glass, porcelain, or earthenwm’e, and be placed outside or inside the excrement receptacle, or formed with it. The distinctive character of this system consists in the employment of human urine at the time of its production as a solvent and absorbent 20 of disinfecting matter, and the application of the urine and disinfectant combined at each usage of the privy or commode, the urine before it is mixed wdth the solid excrement being itself disinfected by the disinfecting matter, and afterwards operating upon the excrementitious substances. 25 Having now described the nature and particulars of my said Invention and the manner in which the same is to be performed, I desire it to be understood that I claim the improved system and apparatus for disin¬ fecting the foecal matters of privies and commodes as herein described and illustrated in the accompanying Sheet of Drawings. 3Q In witness whereof, I, the said Erans Julius Eahlman, have here¬ unto set my hand and seal, this Thirty-first day of October, in the year of our Lord, One thousand eight hundred and seventy- one.
