This invention relates to a marine toilet.

The invention has for its object to provide, in a manner as hereinafter set forth, a toilet of the class referred to including a discharge 5 passage and a normally closed valve positioned at the outlet end of the passage and opened by hydraulic pressure in the form of a jet travelling in a direction towards the valve simultaneously with the flushing of the bowl thereby providing for the discharge of the contents of the toilet.

A further object of the invention is to provide, in a manner as hereinafter set forth, a marine toilet including a discharge passage formed of a vertically and a horizontally disposed branch opening into each other and a normally closed pressure operated valve at the outlet end of said horizontal branch.

A further object of the invention is to provide, in a manner as hereinafter set forth, a marine toilet including bowl and base sections,'a discharge passage in the base section formed of a vertically and a horizontally disposed branch, the vertical branch opening into the bowl section and the horizontal branch having a normally closed hydraulic pressure operated valve, a chamber for receiving flushing water under pressure, a permanently opened jet forming means at one end of the chamber opening into said horizontal branch and directing the jet towards the valve and a flushing water conducting line leading from said chamber to the bowl section.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a marine toilet which is simple in its construction and arrangement, strong, durable, compact, thoroughly efiicient in its use, readily assembled, conveniently installed and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangementof parts as will be more specifically referred to and as illustrated in the accompanying drawings wherein is shown Figure 4 is a section on line 4-4, Figure 3,

Figure 5 is a fragmentary view in longitudinal section taken at right angles to the showing of Figure 1,

Figure 6 is a section on line 6-6, Figure 5, 5

Figure '7 is a section on line 1-1, Figure 5, and

Figure 8 is an elevation of the outlet valve looking towards the outer face thereof.

The water employed for flushing and cleansing the structure is to be under a state of pressure and it is supplied from any suitable source by a pump, not shown, which may be manually operated or operated from an electrical motor or internal combustion engine. The pump is to communicate with a feed pipe line 9 which is an- 5 chored to and opens into the closet structure generally indicated at ID.

The structure H3 includes a bowl or upper section II and a discharge or base section l2 arranged in superposed relation. The bowl sec- 20 tion consists of a flared intermediate portion l3, an upper portion M of any suitable contour in plan and an annular lower portion l5. The portion M constitutes a rim which is of greater thickness than the portion 13. The portion l4 over- 25 hangs the inner face of portion I3 and is formed with an endless flushing water conducting channel 16. The portion I4 is also provided with depending spaced sidewise aligned discharge ports ll leading from the bottom of channel it and opening at the top of portion l3. The portion M at its rear is also formed with a horizontally disposed opening l8 having its wall of two different inner diameters, separated by a shoulder 19. The portion of largest inner diameter of the wall of opening I8 is threaded and arranged outwardly with respect to the other portion of the wall. Mounted in the opening l8, abutting the shoulder l9'and the outer side of portion M, opening into the channel 56 and threadedly engaging with the threads of the portion of largest diameter of the opening it? is a flushing water intake element 23 having attached to its outer end a depending elbow coupling 2|. The upper end of part i3 merges into the outer side of the bottom of the part M. The upper end of portion !5 of section ll merges into the lower end of portion Id. The inner diameter of the portion I5 gradually increases from the lower to the upper end of such portion. The inner face of portion [5 forms a flush continuation of the inner face of portion I3. The outer face of portion i5 is cutout at equally spaced points, as at 22 to form horizontal ledges 23. The portion I5 is provided 55 with openings 24 which extend from the ledges 23 to the bottom of such portion.

The base section I2 in longitudinal section is substantially of inverted T-shaped contour and is hollow. The section I2 includes a top portion 25 or vertical leg and a bottom portion which extends laterally in opposite directions with respect to the lower end of portion 25 and provides a pair of oppositely extending horizontal legs 26, 26 The leg 26 is on the intake side and the leg 26*- is on the outlet side of section l2. The portion 25 is of annular cross section and formed at its upper end with an outwardly directed annular flange 21 of a diameter corresponding to that of the lower end of the bottom of portion [5 of section l2. The flange 21 is provided with spaced openings 28 which align with the openings 24 in portion l5 of section II. The portion 25 has on its outer face a pair of oppositely extending diametrically disposed flared ribs 29 merging at their upper ends into the lower face of the flange 21. The innerdiameter of the leg 25 is uniform. The portion 26 lengthwise thereof is provided with a chamber 39 of cylindrical form for receiving flushing water under pressure. The chamber 30 is open at its outer end and has its wall 3| threaded as at 32. The wall 3| at its inner end is of conoidal contour, as at 33. The pipe line Sextends and opens into chamber 30 at its outer'end and engages with the threads 32. The leg 26 is formed .With a jet opening 34 which extends from the apex of the conoidal shaped inner end of the wall 3|. The section [2 is provided with an outlet passage 35 consisting of a vertical branch 38 formed throughout the leg 25 and a horizontal branch 31 formed in the leg 26 for a portion of the length thereof. The branch 36 at its lower end opens into the inner end of the branch 31. The latter lengthwise aligns with the chamber 30. The jet provided bythe opening 34 discharges into the branch 37 lengthwise thereof. The leg 26 is formed with a vertical opening 38 communicating with chamber '30. Theopening 38 has its wall threaded. Secured to the threads of the opening 38 is a flushing water conducting line 39 which leads from the chamber 30' and is connected at its upper end, as at 40 to the elbow coupling 2|. The leg 25 is formed with a tubular lead-01f 4| into'which the outlet end of passage 35 opens.

The lead-01f 4| has its inner part 42 of greater 7 diameter than its outer part 43 and with the latterpro'vided with internal threads. .The a part 42 of 'thelead-off is of greater diameter than and surrounds the outer end of the passage 35. The inner'part ,42 is cutout at'its top, as at 45 to providean entrance opening therefor. The

' cutout is normally closed by a removable plate 43." The inner face'of the part 42 at its inner end and sides has formed integral therewith-a pair ofspacedendwise aligned'lugs 41 formed with aligned grooves 48 which open at the. inner 'ends and tops of the lugs. These latter provide journals and suspensio'ns for a depending piv- .otally mounted hanger arm 49 for a vertically disposed disc valve 50 arranged in the lead-oil 4| for normally closing the outlet end of passage 30. The arm 49 consists of a curved upper part 5| and an apertured lower part 52. The latter is secured by the holdfast means 53 to the valve 50. The upper end of part 5i carries a pair of oppositely extending pintles 54 which are mounted in the grooves 48. The plate 45 permits of mounting the valve and its hanger arm within the lead-off 4|. Integral with the lower faces of the intake and outlet sides of the base section l2 are the foot pieces 55, 56 which are disposed at right angles and extend laterally in opposite directions with respect to said sides. The ends of the foot pieces are notched for the passage of holdfast means, not shown for anchoring the structure It] upon the floor or a support.

Interposed between the bottom of portion [5 of section II and the flange 2! is a washer 5?. Extending through the aligned openings 24, 28 and through the washer 5'! are holdfast means 58 for anchoring the sections ll, l2 together in superposed relation. 7

When the flushing water is suppliedto. the toilet structure, simultaneously with the flushing action, the jet is formed and acts in connection with that part of the water supplied to the bowl for opening the outlet valve and to'force the contents of the bowl into the lead-off 4|..

What I claim is: v

i. In a marine toilet structure, a top section having its upper portion in the form of a bowl formed of a vertical leg, a horizontal intake leg,

and a horizontal outlet leg, said horizontal legs merging at their inner ends into the lower end of the vertical leg, said intake leg being provided with a chamber for receiving flushing water under compression, the body of said intake leg being formed with means at its inner end to provide a jet opening leading from the inner end of said chamber and opening into the inner end of the horizontal outlet leg, a pivotally suspended valve exteriorly of and for normally closing the discharge end of said outlet leg, and a flushing water conducting line leading from said chamber to the water discharging means in said upper portion, the said jet opening disposed in alignment with the axis of said valve when the latter is in closing position relative tothe discharge end of said outlet.

2. A marine toilet including an upright bow/1,

tended to form a hollow outlet passage, a verti-.

cally disposed outwardly swinging valve for closing said outlet, a large inlet pipe f or conducting water under pressure situated directly facing said passage and valve, said pipe being constricted to form a jet producing nozzle directed im- 7 mediately against said valve to swing'it out wardly, and a tube leading from said pipe .to

flushing means near the top of the bowl.
