WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 492,947, dated March '7, 1893,

Application filed October 25, 1892. Serial No. 449,966. (No model.)

To all whom it may concern: I

Be it known that I, WILLIAM SMITH, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful-Improvements in Water-Closets; and I do hereby declare the following to be afull, clear, and exact description of my said invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to water closets, and particularly to that class of water closets in which the contents of the bowl are discharged partially or Wholly by siphonic action.

In water closets in which the discharging of the contents of the bowl is dependentupon siphonic action it is found that if the descent of the water through the down limb of the exit passage be too rapid, the water will become commingled with air, and the water lacking the requisite density, perfect siphonic action will not be produced, and the contents of the bowl will be only partially discharged. In the efforts heretofore made to overcome this difficulty, and produce an effective siphonic action various devices have been resorted to, such as lengthening and curving the down limb of the exit passage, as instanced in United States Letters Patent No.

376,311, or forming abrupt deflections therein whereby the down limb is given a zigzag form, as instanced in United States Letters Patent No.423,182. But in lengthening and curving the discharge limb the closet is generally made bulky, cumbersome, and costly, and is uncertain in operation unless molded to very exact and uniform measurements; while closets made with abrupt deflections in the down leg of the exit passage have a practically uniform diameter throughout the exit passage,

eter of the down limb while afiording a uniform area of discharge, to preserve theintegrity of the descending column of water while retarding its flow.

I shall now proceed to describe my invention with reference to the accompanying drawings, in which my improvement is shown as applied to an earthenware closet of the siphon jet pattern, and in which Figure 1 shows a side elevation of a closet containing my improvement. Fig. 2 shows a central vertical sectional view thereof from the front to the back of the closet. Fig. 3 shows a section of a portion of the down limb of the exit passage taken on the line ar -0c in Fig. 2; and Fig. 4. shows in full lines a horizontalcross section of the down limb on the line yy in Fig. 3, and in full and dotted lines a horizontal cross section of the same on the line z-z in Fig. 3.

In the drawings A is the bowl of the closet.

Bis the up limb of the exit passage.

0 is the down limb or discharge portion thereof.

D is the passage through which water is conveyed from the supply pipe F to the jet 1) so located at the lower end of the up limb as to direct a stream of water through the center of said limb in the common and well known manner.

E is a passage leading from the upper end of the passage D, and conveys water from the supply pipe F to the flushing rim a. The channel in the down limb is long and narrow in cross section, as shown at c in Fig. 4, and

the diameters of the channel are changed several times throughout the length of the down limb, the greater diameter of one section of the channel being transverse or at right angles to the greater diameter of a contiguous section of the channel, as appears at c and d in Fig. 4, one diameter changing to the diameter of the next section by acurved surface, as indicated in Fig. 3. By the use of this construction of the down limb the contents of the bowl are discharged in a comparatively solid column of water which is constantly changing its form in its descent through the down limb of the exit passage by reason of the chain like form of the passage,

sage of varying diameters and of equal dis- 1 charge area throughout its length; substan- IO tially as shown and described.

2. A water closet having a siphon exit passage of relatively long and short diameters, the long diameter of one section of the passage being transverse to the long diameters of the contiguous sections of the passage; sub- I 5 stantially as shown and described.

WILLIAM SMITH.
