MARINE TOILET 2- Sheets-Sheet 1 Filed March 27, 1946 Patented Mar. 21, 1950 UNITED STATES PATENT OFFICE 2,501,510 MARINE TOILET Angus Roy Gross, Jr.,.Baltimore, Md. Application'March 27, 1946, SeriaINo'. 657,521
This invention is anovel improvement in marine water closets and its principal. object i's'to" provide a water closet-for use on boats and yachts and which will operate efliciently above and below the waterline,- and'which can be installed. cheaply and easily. The present invention an improvement upon U. S. Letters Patent Nos 2,047,866, issued July 14, 1936, to Angus R. Gross. y
The principal object of my invention is to provide. a toilet-which will eliminate many pipe fittings and. joints heretofore required in installing; marine water closets, thereby lessening the cost and time required for installation, and also reducing maintenance charge, my invention comprising a lower pump sectionv for an upper bowl section, the pump. section supporting the bowl section which is directly mounted upon the pump section. When the pump section is secured in placeand connected to the water supply and discharge. pipes respectively, the mere fastening of thebowl upon the pump section completes the water supply andv refuse disposal connections between the sections without requiring any placing or adjustments of pipe connections between thesections.
. I will explain the-invention withreference to the accompanying drawings, whichillustrate one practical embodiment thereof,. to enable others familiar with the art to adopt and use the same; and will summarize in the claims, the novel features of construction, andnovel combinations of parts, for which protectionis desired.
In said drawings: I Figure 1 is a side elevation of my novel marine toilet, partly in section.
Fig. 2 is a horizontal section on the line 2- 2,
Fig. 1.
Fig. 3 isv a vertical section on the line 33, Fig. 2.

ceive holding-down bolts 2 or the like wherebyth base may be firmly secured to a support, the lower end of the casing I being closed by a bottom plate l A drain llcis provided in the lowerend of the cylinder la normally closed by removable plug lm.
- In the lower end of the water inlet lb-is a seat I gfor a lead-corelballvalve 3-, preferably oftread" rubber, andextending laterally of the met lb above the seat lg is a duct l'h adapted to' be connectedwitha water inlet valve casing herein--- after described.
Upon the upper end of the" casing l' is a head c in the form of an inverted cup, same having its upper end closed as at 4a to' embrace the area of the cylinder la and the water inlet lb',
said" head having a soil discharge opening 42) disposed substantially axially'of the cylinder Ia". Headf l has a substantially'circular wall lc closin'g'the upper open end of the cylinder la. Dis
posed adjacent the periphery of the top at of headd is a, water inlet opening 4d registering with the inlet l'b and forming a continuation thereof.
metalmounted on a block. 51) atone side of the 7, opening by means. of a. screw or the.like,.the. outer end of the springba. engaging a fibre or other disc 5d riveted as at 5e to the rubber sheet.
5. concentrically of the opening,4b,-the spring, 5a normally yieldably maintaining the sheet'5 reinforced by discid across the opening. 4b to close same while permitting the valve to-open downwardly by'suction within the cylinder la.
Within thev cylinder la-is a piston 6, which is vertically reciprocally mounted thereinby means of an arm 1 on a horizontal rocker shaft 8 journaled in the casing l, asshown more particularly in Figs. 2, 3 and 6, said arm 1 extending through an. opening lp (Fig. 3) in casing l in the inner Wall of the inlet below the valve. seat lg, andhavingahuh 1a which is-adapted to be clamped aroundthe inner end of the shaft 8, said arm 1 havingits outer end carrying a pin Gwengaging a. slotted bracket-lbthrough aslot Eb, bracket lb being carried by the undersid'efof theapistonhas a bolting flange. lawhich.is-perforatedrto re- 55:; 6;. whereby-when the. shaft 8-isrocked,-.the piston.v
6 will be freely raised and lowered without binding.
As shown more particularly in Figs. 2 and 6, shaft 8 is journaled in a sleeve 9 having its threaded end So secured in an internally threaded boss Iq of the casing I parallel with the bolting flange Is, a suitable packing I (Fig. 6) being interposed between the sleeve and boss. The outer end of the shaft extends beyond the sleeve 9 and through packing (not shown) in an enlarged boss 9b of sleeve 9. Shaft 8 is provided with a bore, in the outer end of which is threaded a grease cup II to lubricate the shaft 8 within the sleeve 9.
On the shaft 8 beyond sleeve 9 is a lever I2 secured thereto in any desired manner. said lever I2 having a handle I3 extensibly mounted thereon and terminatingadjacent the top of the toilet bowl, as shown in Figure 1. By the above construction, when the handle I3 is reciprocated, the piston 6 will be vertically reciprocated in the cylinder Ia.
In the casing I below the inlet port In (Fig. 6) is an inlet port I1", communicating with the inlet I 11 (Fig. 3), which opens into the lower end of the cylinder Ia, and also extending to the under side of the valve seat lg.
The water is supplied to the water inlet Ib from a valve casing I4, shown more particularly in Figs. 2 and 4, the same having an inlet I4a adapted to be connected with the water supply, which may be a gravital supply, where the toilet is located below the water line, or a water pressure supply where the toilet is dispoed above the water line.
Within the inlet I4a is a valve seat I4?) beyond which the water passage Me is enlarged, and then further reduced as at N11 to fit a plunger 15, reciprocably mounted in the cylindrical portion M41, as hereinafter explained. The chamber Me communicates, as shown in Fig. 6, around the plunger I5 through ports Me and Hi, the port Me communicating through port Hg with the water inlet duct In of the casing I, while the port I4 communicates through duct I4h with the duct Ir of the casing I, the ducts I49" and Hit being separated by a wall I4m.
Between the valve seat I41) and the chamber I40 is a valve, preferably comprising a rubber sheet I6, forming not only the valve but a gasket between the sections of the valve casing, sheet I6 having parallel slits Ilia and IE1) at opposite sides of the valve seat I4b to form a loose flap I6c which is reinforced by a fibre or other strip I'I secured thereto by rivet IS, the fibre strip being directly engaged by the plunger I5 to close the valve I6c under normal conditions.
Plunger I5 has a stem I5a extending through the opposite end of the valve casing I4 from the inlet I4d, and a spring I9 within the casing I4 be hind the plunger I5 normally yieldably urges the plunger I5 into contact with the valve I60 to close same against the valve seat I4b.
Rod I5a extends beyond the valve casing I4 and carries a head I5b threaded thereon for adjustment purposes. The head I5?) is engaged by a yoke 20a of a bell crank foot pedal 20, mounted on a horizontal pivot 2| extending from the side of the casing I.
In order to lubricate the rod 15a, a grease cup 22 or the like is preferably threaded into the valve casing I4 between the spring I9 and the adjacent end of the valve casing I4, a suitable packing 23 being provided in the valve casing I4 to prevent leakage of water along the plunger actuating rod I5a.
By the above construction; when the foot pedal 2B depressed, the valve I6cI'I will be permit ted to open, admitting water into the chamber I40, from whence the water flows through the port I4e to the upper inlet port In and thence upwardly past the valve 3 to the port 4d in the head 4. At the same time water is permitted to pass through the port 4 f to the lower inlet port Ir of the casing, from whence the water flows around the lever I through the port Ip and into the'cylinder Ia below the lower end of plunger 6.
The toilet bowl "B, shown in Figs. 1 and 3, is of standard make and is provided with a water inlet B registering at its lower end, as shown in Fig. 3, with the water inlet port 4d; while the central outlet of the bowl registers with the outlet 41) of the head 4. The inlet port B leads to an annular chamber B3 around the upper portion of the bowl, from whence the water is discharged through outlets B4, the water flowing down the inside of the bowl to the discharge portion B2 thereof in the usual manner, the particular form of bowl forming no part of my present invention and therefore needing no further particular description here.
In operation When it is desired to flush the bowl, the operator will depress the treadle '20 with his foot, the extent of depression of the treadle governing the amount of water admitted past the valve IBc-I I. Some of the water passing the valve Hie-l1 will pass directly through the upper by-pass In above the ball valve 3 directly into the inlet duct I!) Iaabove the piston 6 will be compressed and forced laterally through the discharge port Ic of the cylinder past the check valve 25 and through the discharge pipe 26 in the usual manner, the check valve 25 preventing the soil from dropping down the pipe 26 back into the cylinder Ia. During the raising of the plunger 6 the valve 5 will be closed by pressure so that all the soil is forced through the outlet Ic.
When the plunger 6 descends, the valve 5 isopen and the contents of the bowl are suckeddown into the upper end of the cylinder Ia. At
the same time the water below the cylinder is placed under compression and is forced upwardly through the passage Ir, raising the ball valve 3, and thus forced into the water inlet B of the bowl B.
By varying the pressure on the treadle 2ll, the amount of water admitted into the bowl B can be nicely regulated. If the lever I3 is actuated without depressing the treadle 20, no water will 7 be admitted to the bowl B but the contents of the bowl will be first drawn into the upper end of the cylinder Ia and then forcibly discharged. Thus, the supply of standing water in the central portion of the bowl B can be regulated as desired.
I do not limit my invention to the exact form shown in the drawing, for obviously changes may be made therein within the scope of the claims,
