SPECIFICATION forming part of Letters Patent No. 411,455, dated September 24, 1889.

Application filed June 1, 1889. Serial No. 312,859| (N0 model.)

To aZZ whom, it may concern.-

Be it known that we, LOUIS LATTAN and HERMAN TRIPP, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, and JOHN FAULKNER, a citizen of the United States, and a resident of Austin, in the countyof Cook and State of Illinois, have invented new and useful Iinprovelnents in Water-Closets, of which the following is a specification, reference being had to the annexed drawings, (three sheets,) in which- Figure I, Sheet 1, is a sectional elevation of our improved water-closet, taken centrally on line 14, Fig. III, showing the devices for operating the pan below the bowl. Fig. II, Sheet 2, is a sectional elevation taken on line 15, Fig. III, looking in the direction of dart 19, showing the devices for operating the watercloset valve, with a portion of the lower lid attachment projected in front of the plane of section; Fig. III, Sheet 3, a sectional elevation of Fig. II on line 16, looking in the direction of dart 18. Fig. IV is a detail of Fig. II.

The purpose of this invention is a watercloset, more especially to be used on cars, which will haveits pan below the bowl automatically closed by the weight of the person on an oscillating seat and let into the basin a suitable supply of water, and which will by the return of said seat lower the pan and flush the bowl with water. It is desirable at all times that air be prevent-ed from entering the car through the closet, especially in cold weather. Therefore we construct a closet in which the pan is closed when the seat is occupied, and when the seat is unoccupied and the pan is down the closet is closed by a cover. In the patent to Lattan and Tripp, dated on February 26, A. D. 1889, a mechanism is shown for closing the lower end of the closet automatically, which is not essentially unlike the mechanism we employ to operate the pan. \Ve therefore consider such mechanism only in combination with other new devices. The water-valve suitable for the closet requires twenty-eight pounds pressure to operate it. Therefore, to make the closet practicable with this valve for children to use, we have devised the following mechanism:

The closet is drawn to be located in the corner of a room.

A is the front of the closet. B, Fig. III, is one side thereof, and I3, Figs. I and III, is one wall, and S, Figs. II and III, the other wall to the room.

Y is a horizontal board, which is secured to said walls of the room and to the side R and front A in the ordinary way of constructing closets, and the ordinary hole is form ed in the board to receive the bowl 11.

Q represents portion of the floor of the car, which supports, also, in the ordinary manner, a pipe 12, which extends up to support the bowl and down through said floor.

A stationary frame-piece E is secured to the board Y, and to it is hung an oscillating seat D, which is provided with a hole through it corresponding substantially to the size of the hole in the top of the bowl. A connecting-rod 2 is pivoted to the seat D at to, and its lower end is pivoted to the upper end of an elbow-lever 3 6 3 at at, and the lever is pivoted to a bracket 17, which is secured to the front A of the closet. The pan is secured to the arm 6 of the lever 6 3, so that when the seat D is brought down to the board Y the pan 7 and lever 3 6 will occupy the positions shown at dotted lines 8 9 10 for the pan to hold wa ter, as indicated by dotted lines 13.

N represents the water-valve. M isits piston, and 0, Figs. I and II, is the pipe leading from the valve to the basin 11, as the construction now is in water-closets.

The means for operating the valve consists of struts T U. The strut U at its outer end It is jointed to a bracket X, secured to the wall S, (see detail, Fig. IV,) and its inner end 6 is jointed to the strut T, whose outer end is jointed to a plunger-rod L at '13, the said rod having a reciprocating movement in a suitable bearing V to be kept in line.

Attached to the seat D, either by a pivotconncction, as shown at cl, Fig. II, or by a rigid connection, as shown at 2), Fig. III, is a rod F, which is placed inward on the seat D from a Vertical line through the rod I II, that the seat may not he warped by the weight of a person thereon. To connect the rod F with the rod I II, a horizontal elbow IV is made rigid to no lost motion with reference to rod I III On the red I II, at Fig. II, is rigidly affixed a collar Z, which is employed to force the struts T U downward, and that the mechanism may be in line for that purpose a hole m, in aplan of the struts shown at Fig. IV, is made for.

that portion of the rod shown at I to pass through, the hole being elongated to provide room for the rod by reason of the thrust of the strut U when it is brought down to dotted lines f. A bracket K is secured to wall S, to serve as a guide for thelower end of the red I H in its reciprocating movement, and to support a coil-spring J. This spring is placed around that portion of the rod shown at I, and rigidly secured to said portion I is a collar 20, for the purpose of compressing said spring. This construction is such that when the seat D is brought down to the board Y the struts T U will be brought down alittle below a straight line from pivot h to pivot 2', and as a result the piston will be pushed in by the struts, and then returned by a spring inside of the valve operating against the inner end of the piston, so as to push the struts down to dotted lines g g. This lat ter movement will compress the spring J to about one-half of its normal length, so that when the seat D is released the spring J will throw said struts up past the said line from h to z', and the spring in the valve N will then throw them up to their former position; but when the spring is throwing them up the piston M is again pushed in, and the bowl is flooded as the person leaves the seat D. It is found in practice that about a fourteenpound pressure on the seatD will push in the piston M, which requires twenty-ei ght pounds direct force to move. Therefore the spring J at its greatest compression to return the struts to push in piston M and raise the seat D and overcome some friction,the spring should exert a force from eighteen to twenty pounds. The spring being normal when the struts are up, it will require increasing force to bring it down; but at the same time the struts moving down are operated by a decreasing force, which largely makes up for the increasing power required on the spring J. It is therefore by these means that a person of less weight than the force required to operate the piston M may operate the closet.

It is obvious that the relation of the parts need not be maintained, as a U-shaped or other form of spring may be substituted for the coil-spring. A cover 0 is hinged to the back side of the closet, and is provided with a hinged flap G, which hangs vertical when the cover is thrown up back, as shown by (lotted lines 70,, Fig. II, and hangs vertical when the cover is closed and rests on the front A. The cover being above the seatD requires the flap G, and also requires that the side of the closet R opposite to the wall S be brought up to or past the cover to prevent airfrom entering the closet-room when the pan '7 is down.

e claim and desire to secure by Letters Patent-- An improvement in water-closets for cars, consisting of two struts T and U, jointed together at the inner elevated ends, the strut U,jointed to a fixed support, and the outer end of strut T, jointed to a plunger which operates through a guide, in combination with a water-closet valve whose piston is operated by said plunger, and an oscillating seat provided with a jointed rod-connection which extends through the struts and is provided with a collar operating against them and a collar operating against a spring, a coil, a pan below it, and a water-pipe O, communicating with the valve and the bowl, as specified.
