TO ALL WI-IOM IT MAY CONCERN:

Bo it known that' I, FREDERICK HAINsWonTH, of Chicago, in Cook county, and Stato of Illinois, have invented a ne\'v and improved Method of Ventilating Privies or Water-Closets in Railway-Cars and Steamboats; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters oi: reference marked thereon, in which- Figure 1 represents a. vertical central section ofmy invention. l

Figure 2 represents a longitudinal section of the upper and weather portion of my Ventilating-apparatus,

To enable those skilled in the art to make and use my invention, I will describe its construction a-nd operation. l f E E are stationary funnels, upon eith'er end of chamber G, projected above the roof, and designed to face the ends of the cars or boats lupon which this invention may lie-placed, in order that they may receive the p/ressurc of air which is produced by the motion ofthe said cars .or steamboats. A is a valve fitted loosely into the,chamber G, andis guided and supported by the rod a and braces ff. Whe'n the pressure is received into the funnel, it communicates to the Valve A, forcing said`valve against the opposite funnel, and thus closing that passage, which causes the air'to pass in full force down pipe B. D is an outer casing to the inner `shell C, which forms the common privy-seat, with an annular passage surrounding for the downward currents of air. D. is a continuation for a short space of the casing D, for the purpose of continuing and giving momentum to the current of air forced down, which will canse'the central column of air extending up through the shell C to be drawn down and passed olf, es indicated by the arrows in fig. 1, thus keeping the atmosphere in thenapartment above pure and healthful.

In the arrangement of the water-closets now 1n use upon cars and steamb'onts, there is muclrtendency towards a strong upward current of air into the apartment above, filling it with a villainous compound of foul smells stilling to most visitors. It hasalso been observed and experienced by most travellers in cars and steam-4 ers, that the cool air striking against the warm body of the individual, while answering the calls of nature, is very liable to produce a reaction, destroying for the time'the desire and also the power to produce an action,

.thus predisposing the patientto constipation and itsrattendant evils; and delicate persons, especially ladies at critical periods, are thus needlessly and almost criminally exposed to the dangers of. reaction by cold. It is a demonstrable fact that these inconveniences, diiiculties, and dangers will be fully overcome by the use of my invention. i

Having thus fully described my invention', what I claim as new, and desire to secure by Letters Patent of .the United States, is-

A Water-closet ventilator, consisting ofthe case D, pipe B Gr, and valve .A, substantially as described. FREDERICK HAINSWORTH.
