HENRY C. \VEEDEN, OF QUINCY, MASSACHUSETTS.

WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 443,341, dated December 23, 1890.

Application filed September 18, 1890. Serial No. 364,970. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY C. TVEEDEN, of Quincy, in the county of Norfolk and State of Massachusetts, a citizen of the United States, have invented certain new and useful Improvements in Vvater Closet Bowls, of which the following is a specification.

My invention relates to water-closet bowls of the kind which are emptied by siphonic action. In such bowls the bottom of the basin is so formed as to retain a body of water, which fills the same after the flushing operation has ceased. These bowls are ordinarily formed of one piece of earthenware. In these bowls as heretofore constructed it is often the case that an insufficient supply of water remains in the bowl after the flush has ceased. The object of my present improvement is to correct this and to insure a sufficient supply.

In the accompanying drawings I have represented a water-closet bowl embodying my present improvement in the form now best known to me.

Figure 1 is a vertical section, and Fig. 2 a plan. Figs. 3 and 4. are horizontal sections at 00 0c and y y of Fig.1. Fig. 5 is a vertical section at z z of Fig. 4.

I will now'describe the apparatus shown in the drawings. This consists of a bowl A, having a siphon-formed discharge-pipe B, one end of which communicates with the bottom of the bowl, while the other is connected to the soil-pipe or other point of discharge of the contents of the bowl. The bowlA is provided with a flushing-horn O, to which the flushingpipe is attached, and also with a flushing-rim I), through which flushing-water is distributed around the sides of the bowl.

In the rear of the bowl, and between it and the flushing-horn,I form a pair of watenpockets E E, (see Figs. 3, 4, and 5,) arranged, for convenience, on either side of the dischargepipe B. These water-pockets D D, Iprovide at their lower part with small perforations or weep-holes e, passing through the wall of the bowl and communicating with its concave bottom; also in the wall of the bowl, at a point communicating with the flushing-rim and substantially opposite the fiushinghorn, I provide a water-passage F, (see Figs. 1 and 3,) through which, after the flushing-water has entered and filled the pockets above mentioned, its continued flow may pass through the flushing-rim to flush the bowl. The si phon discharge-pipe is represented as provided with a jet-hole G (see Figs. 1 and 3) to start it, this being a well-known device for the purpose, and forming no part of my present invention.

The operation of the device is as follows: WVhen water is turned on to flush the closet, it passes down through the flushing-pipe and enters and fills the pockets E E, which, it should be observed, are of a capacitysutficient to contain enough watcrto fill the bowl to the desired height, after the flushing operation has ceased, by percolation through the contracted orifices e e, above described, at the lower portion of the pockets. The pockets having thus been filled, the surplus flushingwater passes to the bowl, which is flushed in the ordinary manner by siphonic action. When this ceases, the water, as is well known, will stand at a low level in the bowl. The subsequent gradual discharge of the water contained in the pockets E E into the bowl operates to fill the same with water to the desired higher level.

I do not claim, broadly, the combination, with a bowl of the character described, of a chamber within which a part of the flushingwater may be caught and afterward suffered to flow out into the bowl through restricted discharge-0rifices to fill the same to the desired height. My improvement consists in so constructing and locating the pockets relatively to the bowl and flushing-horn that flushing-water first enters the pockets and fills them, thereby insuring a sufficiency of water therein regardless of the subsequent length of the flushing operation of the bowl proper. devices, in which the great bulk of the flushing-water passes immediately to the bowl to flush it, only a portion being diverted into the storage-pockets and filling them while the flush continues. With such a construction, unless the flush is continued for a sufficient length of time, these pockets will not be filled full, and hence sufficient water will not be retained by and discharged from them to fill up the bowl to the desired height.

I claim- The improved water-closet bowl herein de- This is an improvement upon prior IOO scribed, having a siphon outlet-pipe 13, a pair the said Water-retaining chambers being p roof Water-retaining chambers E E, located upon vided with restricted orifices a a, all substaneither side of the bend of the siphon-outlet tially as set forth. and communicating at their upper portions, In testimony whereof I have hereunto sub- 5 as shown, a flushing-horn C, communicating scribed my name this 12th day of September, 15
