'5) for such use which will be so constructed and arranged that it will be sealed against updraft through the closet.
Toilets of thissort are ordinarily provided with a dumpl pan. adapted to be dropped 1n I0. flushing with resultant upflow of air frequently occurring with considerable velocity and producing a blast directed upwardly through thetoilet or closet. This invention contemplates the provision of a closet having means for the elimination of such updraft and'` constructed and designed to protect its flushing by the sealing of the toilet or closet from upwardly or inwardly acting air currents. Y' -k A further object of the invention is the provision in a closet or toilet for use in railway cars and similar locations of improved means for sealing the toilet against updraft, which seals it before the dump pan is unseated and which is held in the sealed position until the dump pan has been reseated, the closet'having generally the construction heretofore provided and operating in all respects as such toilets or closets have in the past. v
A further object of the invention is the provision of simple andk edective means for' sealing a railway closet against upward air movement therethrough, automatically operative as an incident to normal use of the closet and which will not require the provision of parts or devices complicated in structure, expensive in character or requiring particular attention for operation or maintenance.
Numerous other objects and advantages of the invention will be apparentas it is better understood from the following description, which, taken in connection with the accompanying drawings,l discloses a preferred embodiment thereof. n
Referring to the. drawings:
Figure 1 is a side elevation, parts being shown in section, of a railway closet embodying the presen-t invention;
Fig. 21s a view partially infront-elevation 1929. seria1 1-ro.375,243.
and partially in section, showing certain de tails of construction; e
Fig. 3 is an Venlarged sectional detail ofa portion of Fig. 1; l
e Fig.` 4 is a partial elevational view similar to Fig. 1 showing-fthe relation of the parts in the position they assume atthe beginn-ing of the iushingordumping operation;
' Fig. 5 is an enlarged section takensubsta'n-` tial-1y on the line 5-5 of Fig. 3, and
Fig. 6` isa sectional view similar to Fig. 5 showing the relation of parts inthe position they assume at the-beginningof the iiushing or dumping operation. u f
For the purpose of illustrating the lpresent invention, thepdrawings show a closetof the `character generally provided in Pullman and railway cars. `As shown on the drawings, this closet comprises an outer stand or support 11 of usual or preferred type which sup` ports a closet bowl 12 at its upper end. This bowl is provided with an outlet 13 at its bottom, this outlet being normally closed by the water containing dumpfpan 14 which is pivioted upon a shaft 15, journaledas shown in Fig. 2 in opposite sidesof the support 1l. This shaft is provided with a rocker arm 16 fixed uponit to accomplish its oscillation and .connected at 17 by means of an outwardly Y projecting stud 18 rand cotter key 19 with ak link- 21 in turn connected toa flushing or dumpingrhandle or lever 22. Y
It will be understood that the dump pan in moving from the position in Fig. 1 swings downward and to the left in a clockwise direction discharging its contents through a bottom opening 26 of the closet, and in such action provides for free upward air blast through such opening and through the closet.
The invention has for a general object the sealing against such upward air blast through the closet and to this end a closure-35 is provided which is adapted to be automatically arranged to close or seal the opening 26 through the bottom 24 of the closet before the dump pan 14 starts its movement from the closed position shown in Fig. 1. The closure or draft member 35 is fixed to or upon an arm 36 fixed to freelyoscillating shafts 37 and 38 mounted in bearings 39 vformed at or near the bottom of the closet support 11.
The shaft 37 is provided with an arm 41 carrying an eccentric pin 42 arranged for engagement by parts movable with theV dump pan in its dumping action, the construction preferably being such that the draft plate or member 35 is movedto close the opening 26 before the dump pan leaves its normal position and the member 35 remains in sucli closed position until the dump pan is returned to its sealing or original position. Y y
An inwardly extending sleeve or hub portion 43 isl the means for fixingjthe arm 16 upon the shaft 15 to accomplish the oscillation of the shaftr as above mentioned, and as shown in Figs. 5 and 6. This sleeve or hub portion 43 encircles the end of the shaft 15 and is provided with an aperture or slot 44 lfor receiving the head of ajrocker pin 45 carried in the shaft. 15 so that the sleeve 43 may be rotated through an angle before the end of the aperture 44 engages the pin 45, causing rotational movementof the shaft 15 in dumping the dump pan 14 as an incident to the flushing of the closet. This initial movement of the sleeve 43 about the end of the shaft 15 moves the draft member 35 into and out of operative or sealing relation with the closet support by a mechanism which will now be described.
An arm 46 is yfixed upon the sleeve 43 of the arm 16 byv means of bolts 47 to oscillate with it and this arm carries an arcuate member or segment 48 being-secured thereto by lock screw 49.' The arcuate member or segnient 48 is provided with a cam surface 51 adapted to ride over the offset pin 42, already mentioned, and hold the draft plate 35 in position to close lthe opening 26 through the closet. When the dump pan and the draft Vmember are in normal position, the offset pin v42 is arranged in a recess 52 at the endof the arcuate or segmental member 48, the plate 35 being disposed without the influence ,of this part 48.
Viewing Fig-4, it will benoted that immediately upon initial dumping movement of the sleeve 43 of the arm 16 by the link 21 and handle 22, the arcuate member 48 presses down the pin 42 and swings upwardly and into closed or sealed position the draft plate 35, without moving or unseating the dump pan 14. It will be apparent also that furtherdumping movement of the handle 22 swings the pan 14 downwardly to the left, as shown by the broken lines in Fig. 4 and causes the outer cam face 51 to ride over this offset pin holding the draft plate 35 in closed position, the end of the aperture 44 engaging the pin 45 and imparting movement to the shaft 15 for opening the pan 14. The draft member 35 is formed with a heavy portion or counterweight 53 at its front' to overbalance the draft plate or member 35 to move it and maintain it in the inoperative position shown in Fig. 1, and it will be understood of course that the initial dumping movement of the lever 22 acting upon the pin 42 lifts this counterweight and positively moves the draft plate35 to the position shown in Fig. 4 where it is heldthereafter by the action of the arcuate or segmental member 48 on the pin 42 caused by theI dumping movement of the dump pan 14. l v
The closing of the draft member 35 and thereafter the dumping of the dump pan are accomplished by an upward pull on the hand lever 22, this being the action in the flushing of the closet. Thereafter the weight 24 returns the parts to normal position.- I have provided means for insuring the movement of the draft plate 35 from the closing or sealing position shown in Fig. 4 after each return of the dump pan to its normal or receiving position, this movement occurring preferably after' and only after the completion of the return movement ofthe dump pan. Upon return movement of the dump pan,"the segmental member 48 slides over the offset pin 42 holding it in position to maintain the draft member 35 in the sealing or closed position until the end of the return 'movement of the dump pan 14. At the end of the movement of the dump pan the offset pin 42 enters the recess 52 and is thereafter immediately engaged by ahook member 54 integralwith the arcuate or segmental member 48 to positively swing the draft member 35 to its non-obstructing position as illustrated in Fig. 1. Y
The counterweight or heavy portion 53 of the draft member tends toy return the draft member 35 to this position and serves to hold it in such arrangement until subsequent flushing of the-closet.
It will be noted that the valve mechanism 23 in flushing out the dump pan 14 delivers its contents to the draft member 35 together with the attendant flushing water which 'serves to cleanse this draft member upon its return to the non-closing position shown in Fig.f 1 after use.
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 inventionV or sacriicing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
I claim:
l. A water closet, comprising a closet bowl supported above its base, a dump pan positioned beneath the bowl and adapted to swing from a sealing position downwardly to a dumping position, a draft member located beneath the dump pan and movable into a position sealing the outlet of the toilet, a cam having pivotal movement about the axis of movement of the dump pan and for controlling the movement of said draft member, and a connection between said cam and said dump pan established at the end of the closing movement of said draft member for dumping said dump pan.
