WATER-CLOSET FOR CONVEYANCES.

SPECIFICATION forming part of Letters Patent N o. 710,989, dated October 14, 1902. Application tiled January 1 0, 1902. Serial No. 89,113. (No model.)

To coll whom. t 11m/y concern:

Be it known that I, DANIEL H. MURPHY, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Tater-Closets for Conveyances, of which the following is a specification.

This invention relates to water-closets for railway-cars and other conveyances; and its object is to improve the construction thereof, whereby access of insalubrious cold drafts to the seat is prevented and the flushing and ventilation are improved. Y

In the accompanying drawings, Figure 1 is a perspective view of the preferred form of my improvements. Fig. 2 is a partial plan. Fig. 3 is a sectional view showing the position of the parts when in disuse. Fig. 4 is a detail of a flushing-valve, and Fig. 5 is a seetional elevation of another form of one part of the invention.

In the several views similar parts are desi gnated by similar characters of reference.

The door of the car is indicated at A, the end wall thereof at B, and the side Wall at C. To the Wall B is preferably hinged a closetseat 20, adapted when down to lie upon a fixed bench 21. Secured to the iioor of the car by means of hinges 22 is a vertical box or funnel 23, whose open upper end stands beneath the seat opening or jamb 24 in the bench 21 and whose open lower end protrudes through a floor-opening A. By means of a link or connecting-rod 25, which is attached at its lower end at 26 to the lower portion of said funnel 23 and at its upper end at 27 to the side edge of a seat cover or lid 28, said funnel may be tipped upon said hinges 22 from the vertical full-line position at Fig. 1 to the inclined full-line position at Fig. 3, at which figure it is shown as forming a continuation or lower section of a Ventilating-shaft 29, the upper portion whereof opens into the outer air, preferably at the top of the car.

A valve 30 is connected by hinges 31 to the under side of the car-floor, Fig. 3, and is provided With a counterbalancing-weight 30X, tending to keep said weight up, so as to close the door-opening A', one corner of the box, as 23, being adapted to bear down upon said valve and open the same when said box is tipped to the Fig. 3position.

Upon the cover 28 is provided a pin 32, adapted to be engaged by the latch 33, secured to the end wall B of the car, this latch being preferably connected by a cord 33 to the door 34 at the entrance to the closet, Fig. 2, so that when the latter is opened the latch is automatically released, therebyrpermitting or causing the cover to fall and the funnel 23 to tip to the Fig. 3 position.

In the lower portion of the ventilator 29 is provided a spraying or iushing jet 35, communicating with an oil-tank 36, and between said tank and said jet is inserted a four-Way valve 37, Fig. 4, having a four-tooth ratchet 38, controlled by a spring-pawl 39, mounted upon a lever 40, said lever being connected by a link 41 to a crank 42, carried bya rock- 7o shaft 43, upon which the cover 28 is mounted, so that `when said lid is moved said lever 40, link 41, and crank 42 are operated, thereby turning the ratchet 38 and the valve, and hence permitting the escape of a quantity of oil through the latter into the jet 35, spraying the funnel 23. The valve is closed by the final portionof the movement of the cover 28. The oil does not freeze, and is used in small quantities to spray or flush the funnel, and serves to minimize the adhesion of excrementitious matterV to the walls thereof.

At Fig. 1, in which the parts are shown in position for use, it will be observed that the valve 30 closes the floor-opening A', so as to Acheck or prevent ingress of cold exterior air through the funnel to the seat, While the top of the funnel preferably registers with the opening in the bench 2l so closely, as shown by dotted lines at Fig. 3, as to also prevent cold air coming through the ventilator 29 gaining access to the seat, thus rendering the apparatus far less liable to lead Vto sickness or injury than Where the seat communicates by a fixed funnel directly with the outside air, as is customary. In other words, the apparatus as shown in Fig. 1 is in the form of a closed commode, the ventilator 29 at the time preferably serving to purify the aiuof the closet, while in Fig. 3 position the funnel 23 is entirely out of communication with the closet and wholly in communication with the ICO ventilator at one end and the open air at the other end, whereby contamination ot the air of the closet is wholly avoided.

At Fig. 5 a cover 2S is shown connected by a link 25 to a box or funnel 23, forming the lower section of a ventilator 29, said funnel being hinged at its lower end at 22a to the side C of the car and being moved by the link at the raising of the lid to the position of use, (shown in dotted lines at 232) at which time the lower end 23c of the funnel contacts with the wall C, so as to close said funnel and prevent an indraft of air, said end 23C being cut diagonally for this purpose. It will be observed in this instance that the air valve or trap is fixed to or forms a continuation or portion of the side C of the car, as at 30, the movement of the funnel 23c serving to close and open the valve or at least to put said funnel into or out of communication at its lower end with the outside air for the purposes set forth. i

In using herein the term complete funnel I mean to distinguish from an open trough or pan. It is to be observed that my funnel is a complete four-sided device, so that the closet is necessarily kept clean and free from odor, which would not be the case with an open trough, and at the same time cold drafts are prevented from gaining access to the seat when in use. It will also be seen that preferably the funnel when out of use forms au entire section of the ventilator. It is not essential in all cases that the funnel be square or box-like in construction so long as it forms a complete inclosure.

Variations may be made within the scope of myinvention, and portions of myimprovements may be used without others.
