My invention relates to marine toilets.

Animportant object of the invention is to provide apparatus of the above mentioned character, embodying the minimum number of moving parts, whereby the construction is extremely simple, cheap to manufacture,

and not liable to disarrangement.

A further object of the invention is to provide a single valve device for controlling the passage of flushing water, to the bowl, with simple means to control the action of the valve elements of the valve device.

Other objects and advantages of the invention will be apparent during the course of the following description.

' In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same, a

line 77 of Figure 4.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral 10 designates a bowl, provided'at its bottom with a tubular outlet neck 11, connected with an outlet pipe 12. The bowl 10 may be formed" of porcelain or the like,while the outlet pipe 12 is preferably formed of bronze or any other suitable non-corrosive material.

Arranged above the outlet pipe 12 is a ver Connected with the lower end of the cylinder is a T-coupling 14:, also preferably formed,

of bronze and suitably connected-with the outlet end of the pipe 12.- A discharge pipe 15 is connected with the outlet end of the. T coupling and leads to any desired remote point. I V Mounted upon the top of the cylinder '13 isa head" or cap 16, preferably formed of bronze, equipped with a stuffing box '17, receiving a reciprocatory plunger rod 18 extendii ig into the cylinder 13. Rigidly connected with the free end of the plunger rod 18 is a plunger 19, of any well known or preferred construction, and equippedwith suitable packing. The plunger rod 18 and the metallic parts of the plunger 19 are preferably formed of bronze. It is thus seen that the cylinder 13 has communication, beneath the plunger 19, with the bottom "of the bowl 10."

The numeral 20 designates a casing of a single flushing valve device; This casing is provided with a depending tubular neck 21, for connection with a pipe, not shown,

which leads to a source of water, such as to the oceanlevel. The caslng 20 is preferably formed of bronze. This casing is provided upon one side with a horizontal tubular neck 22, externally threaded for engage- Y ment within a screw-threaded coupling 23,

formed upontlie side of the cylinder 13, adjacent to'its upper end, whereby the'casing 20 is in communication with the cylinder upon the upper side of the plunger 19. I

The casing 20 is provided at'its top with a screw-threabled tubular'neck '24,'for engagement with a coupling sleeve 25, having an upper horizontal flange 26,- to engage upon the top of'the flange 27, formed upon an elbow 28, which is preferably formed of bronze. Suitable packings29 are arranged The elbow 29 is connected to a flushing pipe 30, leading into a tubular portion 31, which in turn leads into the upper 'portiOn of the:

bowl.

The valve device casing 20 is provided upon its opposite sides, Figure 6, with trunnions 32, upon which are pivotally mounted the'lower ends of links 83, which converge upwardly and are apertured for receiving a connection, including a generally vertical arm 36 and a generally horizontal in37, which are preferably formed-integral with each other and with-the lever. The rear end of the horizontal arm 37 is apertured' *and' is pivotally connected with the top' of the plunger rod'18 by means of apin 38 or the like. The lever 35 is preferablylpro- "vide'd with an aperture 39. Shouldit be .erably formed of '43, preferably formed of brass.

.erably formed of preferred tov have the lever generally horizontally arranged, the horizontal arm v37 is disconnected from the rod 18 and links 33, and the lever is inverted and its forward end again pivoted to the pin 34 while the pin 38 is passed through the aperture 39.

The outlet end of the T-coupling 14 is provided with a horizontal valve seat 40 having an opening 41 formed therein. The opening is adapted to be closed by an upwardly opening check leaf valve 42, prefleather or other flexible carrying upon its top a weight The outlet pipe 12 is provided at its outlet end with a horizontal valve seat 44, having an opening 45,. adapted to be covered by an upwardly opening leaf or flap valve 46, prefleather or the like, and provided upon its top with a weight 47, preferably formed of, brass. As more clearly shown in Figures 5 and 6, the valve casing 20 is provided in its bottom above and ad jacent to the tubular neck 21 with an opening 48, surrounded by a tapered or conical valve seat 49, adapted to receive thereon an upwardly opening rolling or ball valve element 50, preferably formed of brass, composition, orany other suitable non-corrosive material. In. the upper portion of the casing 20 and adjacent to the lower end of the tubular neck 24 thereof is a web 51, having an opening 52 formed therein, and a tapered or conicalva-lve seat 53 formed upon its top, for engagement witha rolling or check ball valve element, 54. This check ball valve element may be formed of brass, composition,

material, and

, or any other suitable material. Arranged above the check ball valve element is a stop element 55, formed of bronze or the like, to limit the upward movement of the ball element, 54, but not perceptibly interfering with the passage of water.

The numeral 56. designates a tubular bonnet preferably formed of. bronze and having a reduced screw-threaded portion 57, engaging within a screw-threaded tubular neck 58, formed upon the casing 20. A rotatable rodor shaft 59 extends through this bonnet and, is provided at its outer end with a handle or crank 60,. to turn the same. A

transverse pin 61 carried by the inner portion of the shaft 59 slidably engages the bonnet 56 and prevents the shaft 59'from moving outwardly in a longitudinal direction. The shaft 59 is. provided at its inner end with a pair of. diametrically arranged radially extending shifting lingers or lugs 62, preferably formed integral therewith. One of these lugs is adapted to engage the lower ball element. 50 while the other lug will simultaneously engage the upper ball element 54, thus retaining the lower ball element seated and holding. the upper ball element from its seat.

The operation of the apparatus is as follows:

Upon the up stroke of the plunger 19, the contents of the bowl 10 are withdrawn through the pipe 12 and enters the lower portion of the cylinder 18 and coupling 14, beneath the plunger, the valve 42 closing upon the up stroke of the plunger and the valve 45 opening. Upon the down stroke; of the plunger, the valve 45 closes andvalve 42 opens and, the contents are discharged through the pipe 15, as is obvious. Upon the up stroke of the plunger 19, as above explained, ball valve element 50 is seated, while ball valve element 54 is unseated and the water contained in the cylinder 13 above the plunger 19 is forced through the flushing valve device and pipe 30 to the upper portion of the bowl Upon the down stroke of the plunger, 19, ball valve element 54 is, seated while ball valve element 50 is unseated and water is supplied to the cylinder 13, above the plunger 19 to fill the same. Y

It frequently occurs that the valves 42 and 4 may become wholly or partly inoperative 9 without supplying additional flushing d that it is desired to operate, the plunger water to the bowl, as such supply might.

cause the bowl to overflow. this situation, the handle 60 is turned for about afourth of a revolutionand the fingers 62 will hold the lower ball valve element seated while the ball valve element 54 is.

held from its seat... The seating of the ball valve element 60 cuts o'lf, the further supply of the flushing water, and the retaining of the ball valve element 54 unseated breaks the vacuum which might otherwise occur in the cylinder 13, above the plunger, thus permitting of the free and easy reciprocation of the plunger.

Particular attention is called to thefact that I employ a single flushing valve device embodying the two ball valve elements. This greatly simplifies the construction of the apparatus. The ball valve elements being free to turn or roll upon their seats, tendto clean themselves and the seats, preventing cor roding. The arrangement of the ball valve elements in close relation permits of the control of their operation by the single shaft 59.

it is to be understood thatthe form of my invention, herewith shown and described,

is to be taken as a preferred example of'the same, and that various changes inthe shape, size and arrangement of partsv may be resorted to without departing fromthe spirit of my invention or the scope of; the subj'oined:
