This invention relates to a toilet and especially to a. device of this character which is particularly intended and designed for-use on passenger carrying 'vehicles' such as long distance buses but it is understood, of course,

. that a toilet in accordance with this invention may be used in 'any manner for which u same may be found adapted and desirable.

An important object of-the invention is to provide atoilet of the aforementioned char-i acter which willbe very 'compact in-,construcy `tion and arrangement,`thereby requiring 'a minimum of'space in the vehicle in which 7same is installed. y

j Another very importantobject of the invention is to provide in a manner as hereinafter set forth, a toilet of the character devide a' toilet of the character set forth which will be simple in construction, strong, durable, efficient and reliable in operation, and which jmay l be manufactured and installed at low cost.

jects and advantages of the invention will b'ecome apparent fromv a study of the following specication, taken in onnection with the accompanying drawings herein like characters .of reference designate corresponding parte throughout the several views, and wherein and partly in vertical section through at'oilet constructed in'accordance with the present in-f vention.

Referring `now tothe drawings in detail, it

will be seen that 'the'reference numeral 1 des- .ignatespa housing of suitable shape and size havingan open` side disposed' in abutting env A11 of the foregoing imagen further 0b;

gagementwith a wall2 of the vehicle or'other l be had to theJ interior of the housing 1 for a purpose which willbe more fully hereinafter set forth.`-/Abovef the housing 1 the wall 2 is further provided with a recess or depression 4, the'purpose of which willalsolbe presentlyset forth.

A bowl 5 having a rim portion 46. thereon is mounted by \a hinge 7 fo swinging move- "ment 1 n`a vertical plane on the housing 1 toward and away from the recessed portion 4:l of the wall 2. The hinge construction which 4 connects the bowl 5to the hosing 1 is such that the downwardy swinging movement of said bowl will be arrested when "the bowl is ure 1, When the boy l is swung upwardly,

, the rim portion 6 thereof is adaptedto enter the recess 4 of the wall 2, as seen in Figure 2 l Yof the drawings.'

An arcuate, telescopic sectional pipe 8 extends from the rear upper portion of the bowl 5 downwardly into the housing 1 through an opening provided therefor in the top ofsaid `housin l and terminates in an elbow 9 vwhich `downwardly'directed discharge rbranch which is' detachably connected to the tapered neck 10 of aseptic tank 11 which is removably disposed in the housing 1 in a manner to provide Figure 1 1s a view partly 1n side elevatlon afleakproof joint through the mediumof a suitable couplingy clamp 12 whichisillus'- tratedto advantage in Figure 3 ofthe draw- 1n nected Jaws havin suitable means on their goove for the 'reception ofthe tapered 4nec Fi re 1 of the drawings.

e reference numeral 13 designates a backrest vwhich is mounted for vertical 'swilging movement in a direction at right angles to 10 and the tapered '.iiange onl the lower end of the elbow 9, as best seen in i l 4is rigid y mounted inthe-housing. The elbow" i A gs. It will be seen that the clamp 12 comy prlses a pair of complementary, pivotallyconmounted on the housing 1 coaxially with the bowl 5 and is operatively connected to said bowl in a manner to yieldingly -urge same upwardly to raisedor inoperative position as at 17. A cableP18 has one end connected to the operator 16 for actuation thereb and is .trained over suitable pulleys 19 an has its other end connected to thefree end portion of the arm of the back rest 13, as illustrated I to advantage in Figure 4 of thedrawings.

Thus, when thel operator 16 swings the bowl 5 to its raised or inoperative position,'the

back rest 13 will, through the medium of the cable 18, beswugng upwardly to 'ts inoperative position as indicated in bro en lines in Figure4 of the drawings' to permit the rim.,

portion 6 of the bowl to enter the recess or depression 4 in theWall 2.

The reference numeral 20 designates a water/ storage tank or reservoir which is mounted on the wall 2 or on any other suitable structure@ above the back rest 13.' A measuring container 21 is connected to the lower end of the reservoir 2 0 by a valved couplin 22. The reference numeral 23 designates a u'sh pipe which is connected to the measuring'con -talner or tank* 21 bya valve `24. The flush pipe 23 terminatesin a substantially U-shaped lower end-portion which is formed to accommodate the vfree end portion of the bowl 5 when said bowl is in its raisedor inoperative position, the vfree end portion of the Hush pipe projecting into the bowl in the manner illus.- trated to advantage in Figure 2 of the drawings.

operation in the form of arod 25 having its lowerend pivotally connected to one end of a pivotally mounted bell crank lever 26. A suitable spring 27 normally maintains the valve 24 in its closed position and the upper yvalve 22 in its open position.

iso

The reference numeral 28 designates an air valve which isconnected y a pipe 29 with the upper lend of the measuring container or tank 21. The air valve 28 is connected by a vplpe 30-.with the air brake system of the vehicle or with any other suitable source of air pressure supply. The valve head of the air valve 28 is mounted on a reciprocating stem 31 having a coil springoperatively connected thereto for ,ieldingly urging the valve` toward itsclosed position. On its lower end the'valve stem 31 is providedl with suitable` spring controlled pivoted means disposed in the path of the upper end of the rod 25 for engagement and actuation thereby. in a manner to open the valve 28 when the rod 2.5 is moved upwardly but to permit downward movement The valves v2 2 and 24 are provided with common actuating means for simultaneous the reservoir 20 while the bowl is in use.

"remvin the coupling clamp '12.

of Ithe rod 25 independently ofthe valve 28.Y In use, the bowl 5 is swun downwardly from the position illustrated 1n Figure 2 to 'state that the telescopidarcu'ate pipe 8 is disposed concentrically withl the .axis about which thef'bowl 5 swings. After bein used,- the bowl 5 is again swung upwardly luy the" 80 operator 16, the sections of the ipe 8 telescoping Within each other and t e cable 18 again swinging the back rest13 outwardly and upwardly to its inoperative position to permit the rim portion 6 of the bowl to enter 85 the recess or depression 4 in the wall 2. When the bowl enters thefrec'ess or depression 4, the upper end portion thereof engages the free end portion of the bell crank lever 26 in a manner-to swing, the rod 25 upwardly and 90 open the valve 24 and close the valve 22.' This same movement ofcthe vrod 25 opens air valve 28 to admit air under pressure into the upper end of the measuring tank or co1npart-' ment 21 andthe water therein will be dis- 95 charged through thepipe23 with considerable force into the upper portion of the .bowl

5 in a manner tothoroughly flush said bowl, the .flushing water passing downwardly through the'telescopi'c pipe 8 intothe septic tank 11.' It will be seen that the pressure of the air is addedto the force of gravity on the flushing water which passes downwardly through the pipe 23.A It may be well to here vstate .that when thesbowlf is swung downwardl for use, the spring-27closes the valve 24 and opens the valve 22 ina mannen-'to permit the measuring tank 21V to be illedfrin viously, when the bowl is not in use and has lSHO been flushed thev measuring tank 21 is empty and the valve 42,2 is closed'. The tank 11 maybe'expeditiously removed and replaced through the, hinged door 3' byv It is elieved that the lmany advantagesofatoilet constructed in accordance with this invention will bev readily understood, and although the'preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details lof construction, and -the arrangement of i parts ma lbe resorted to without departing from th s irit of the invention as claimed. 4
