4 Claims.

This invention relates in general to improvements in water closets, and has more particular reference to improvements in water closets, having a. movable dump pan, for use in vehicles.

A principal object of the invention is the provision of novel means for preventing accidental disengagement of the dump pan actuating member.

Another important object of the invention is the provision of a water closet for vehicles in which the closure member may be easily assembled without undue waste due to breakage.

Another important object of the invention is the provision of a ceramic water closet for vehicles in which the foot portion is of uniform cross-section and of sufficient thickness so as to strengthen it against any undue strain that might occur when the water closet is either in transit or when set up for use.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, when taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

In the drawings:

Figure l is a side elevational view of the improved water closet showing the dump pan mechanism in normal position;

.Figure 2 is a front elevational view of the improved water closet;

Figure 3 is an enlarged cross section taken substantially on line 3-3 of Figure 2, of the removable portion of the dump pan; and

Figure 4 is a fragmentary view of part of the actuating mechanism, illustrating the means for preventing disengagement thereof.

Referring more particularly to the drawings, reference numeral H indicates in general a water closet or hopper comprising a bowl l2 and a stand or supporting portion l3 formed integrally therewith. The water closet H is cast or formed in one piece, preferably a vitreous china, although any other suitable material or metal may be used.

A dump pan l4 normally closes the lower end of the bowl l2, as shown in Figure 2 and is fixedly mounted on a transverse shaft I5 extending through and suitably journaled in the side walls of the stand portion I3 of the water closet I I. The dump pan and operating mechanism therefor will be briefly described herein, a more complete and detailed description of similar mechanism being given in United States Letters Patent No. 1,992,653.

An arm, not shown, fixedly secured to the shaft l5 at one end, is provided with a pin I1 extending into a slot l8 which is provided in the lower portion of a link IS. The opposite end of the shaft I5 is equipped with an arm 2| carrying at its free end a counter-weight 22 for normally holding the dump pan M in closed position (Fig. 2).

The link I9 is pivotally connected at 23 to one end of a link 24. The other end of the link 24 is pivotally connected to a foot lever 25. The upper end of the link I9 is pivotally connected at 20 with a lever 30 which is connected with a flushing valve 26 of any preferred or desired construction, so that upon raising the link 24, by means of the foot lever 25, the movement of the dump pan H to open position is initiated while at the same time the flushing valve 26 is set in operation in order to thoroughly flush the interior of the bowl l2.

Within the lower end of the stand portion l3, directly below the bowl l2 and dump pan I4, is positioned a funnel-shaped downwardly extending member 21 (Figs. 2 and 3). The member 21 is detachably associated with the stand 13 so that the dump pan I4 is easily accessible, either for repairs or removal. The upper flaring edge 28 of the member 21 abuts against a shoulder 29 formed within the interior of the stand I 3. A gasket 31 is used to make the joint between upper flaring edge 28 of the member 2'! and the shoulder 29 water tight and to prevent any seepage therethrough. While in the instant case a rubber gasket 3| is used, a non-soluble cement or putty is also used to help make the joint tight, but it is to be understood that other gasket materials may also be used such as lead, treated waterproofing material, or the like. Cast integrally with the side walls of the member 2'! and extending outwardly therefrom are a plurality of protuberances 32. Fastened to the interior of the side walls of the stand l3, by means of bolts 33 or the like, are a plurality of inverted L-shaped members 34, which are adapted to abut the protuberances 32. Small set screws 35, Fig. 3, are screw-threaded into the inwardly extending portion of the members 34 and when tightened will force the member 21 upwardly so that the edge 28 will be securely held in place against the shoulder 29.

A pair of oppositely disposed bearing

members

36 and 31 are formed integrally with the stand l3. A shaft 38, journaled in the bearing 35, carries an arm 39 loosely mounted thereon at one one end and an arm 4| fixedly mounted thereto, the former having a bifurcated end 42 which loosely supports it on the shaft 38. The other end of the fixed arm 4! is yieldingly connected to the arm 39 by means of a coiled tensioned spring 43.

Extending inwardly from the arm 39 is a pin 44 which is fastened to the arm 39 by means of a rivet 45 or the like. Formed integrally with the pin 44 is an upstanding arm 45 having the upper end 41 bent at approximately a right angle to the arm 46, the purpose of which will be more fully described hereinafter. The pin 44 is normally adapted to rest in a suitable aperture 48 which is formed in one end of a segment lever arm 51. The outer periphery of the segment lever arm 51 is in the shape of an arc of a circle having its center at the center of the shaft 15. The segment lever arm 51 is adapted to come in contact with the pin 44 and is fixedly mounted on the shaft 15 in any well known manner. A protuberance 49 is formed in the other end of the segment lever 57 and is adapted to bear against the stop member 46 when the segment lever 51 is in the position shown in Fig. 4. An arm 5| is rigidly secured to the segment lever 51 and has a weight 52 pivotally mounted at 53. The weight 52 tends to move the segment lever 51 upwardly to its normal position as shown in Fig. 2.

Journaled in the bearing 31 is a shaft 6| which has fastened to it at its outer end an arm 62, which in turn is fastened to a weight 63. Fastened to the inner end of the shaft 6| and disposed interiorly of the stand portion I3 is a downwardly extending arm 64, and a corresponding arm 65 is also fastened to the interior of the shaft 38. The lower ends of the

arms

64 and 65 are in turn fastened to a draft member or sealing plate 65 which is adapted to close the lower open end of the member 21.

The draft plate 66 is normally held in a partially open position so as to facilitate operation thereof since it requires less effort and a more simple mechanism to operate same from a partial- 1y open position than when the draft plate 66 is held in a normally closed position. However, when the foot lever 25 is pressed downwardly, the link 24 will move upwardly causing the link it? to move which in turn will move the pin IT. The moving of the pin I! will cause the segment lever 57 to rotate about the shaft l5 and come into contact with the pin 44. The initial movement of the segment lever 51 causes a movement of the arms 39 and 4|, and this in turn causes the shafts 38 and GI to rotate and thus close the draft plate 65. Upon the continued upward movement of link 24 the dump pan 14 again closes the opening in the bowl l2. Upon return to normal position of the link 24 the dump pan Hi again closes the opening in the bowl l2 and the draft plate 66 opens to allow the refuse to be emptied.

It has been found that the continuous opening and closing of the dump pan l4 and draft plate 65 will cause the segment lever 51 to move past the pin 44 and prevent the re-engagement of the pin 44 and the segment lever 51. The extra travel of the segment lever 51 is due to a number of things that happen while the closet ii is in service as; the usual bumper or shock absorber of the foot lever 25 becomes worn through constant wearing thereof; the shock of stopping may also be taken by the dump pan I4 and become dented; the bearing portion in which the shaft I5 is journaled will oftentimes become slightly worn. To overcome this overtravel of the segment lever 51, the arm 46 was added to the pin 44, and the protuberance 49 was added to the segment lever 51. Thus it will be seen that even though these different factors may occur, the segment lever 51 will always be in engagement with the pin 44. This is shown more clearly in Fig. 4, wherein it will be seen that the protuberance 59 will strike the arm 46 and prevent further movement thereof.

By casting the bowl [2 and stand portion [3 inprimary importance.

tegrally, a much lighter construction is provided than those employing a separate bowl and stand, as shown in the patent above referred to. The construction thus provided will permit ready removal of the water closet H for cleaning and repair service, and is particularly adapted for use in vehicles, especially those in which weight is of The construction of such a closet ll permits strengthening of the foot of the stand portion [3 by the adding of extra material thereto and was not contemplated or thought to be possible without interfering with the means of attaching the closure member 21. The assembly of the dump pan [4 and closure member 21, therefore, is greatly simplified.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
