PORATION OF MASSACHUSETTS.
WATER-CLOSET BOWL Specification of Letters Patent.
Patented May '21 1907.
To all whom it may concern:
Be it known that I, GEORGE .W. KNAPP, of
Stoneham, in thecounty of Middlesex and State'of Massachusetts, have invented certain new and useful Improvements in Water- Closet Bowls, of which the following is a specification.
This invention has relation to water-closet bowls, and has for its object to provide certain improvements therein whereby better ventilation may be secured for the prevention of malodorous gas or air escaping from I the bowl, whereby water will be prevented from passing into the vent-pipe upon a stoppage in the soil pipe or an obstruction lodging in the trap, and whereby numerous other desirable objects may be attained.
To these ends the invention consists in a water-closet bowl embodying certain features of constructionand relative arrangement of parts, all as illustrated upon the accompanying drawing, described in the following specification, and pointed out with particularity in the claims hereunto appended.
Reference is to had to the accompanying drawings, and to" the letters and figures marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case. may be, wherever they occur.
Of the drawings :Fi ure 1 represents in plan view a water-closet owl embod ing the invention. Fig. 2 represents a side ei evation of the same. Fig. '3 represents a longitudinal vertical section through the bowl. Fig. 4 represents a horizontal section on the irregular dotted line 44 of Fig. 3. Fig. 5 represents a vertical section through the neck of the bowl on the line 55 of Fig. 3, looking in the direction of the arrow.
The invention is illustrated upon the drawing as being embodied in a bowl of the siphon-jet type or variety, and some features of it are limited to such a bowl, but so far as other general features of the invention are concerned, the latter may be embodied in a wash-down or other bowl, as will be readily apparent to those skilled in the art to which the said invention appertains.
Heretofore, with but few exceptions, closets have been ventilated by ducts leading from the side of the bowl, and consequently f to meet the requirements of the trade, it has been necessary to keep in stock both right and left bowls, t. e., bowls in which the ductleads from theright and from the left sides respectively. Consequently, in order to save maintaining a large number of bowls on hand, my invention comprehends a construction in which the ventilating flue projects rearwardly in the median line of the bowl and I which therefore possesses features which are highly desirable.
In addition, we provide for the water-supply duct and the ventilating duct passing through. the same neck which is partitioned for this purpose, and which extends rearwardly far enough 'to pass through a partition or wall, whereby the flushing pipe, the tank, and all other parts of the water-closet, except the bowl, may be hidden from view. Such an arrangement of parts is especially desirable for factories, school-houses, government and corporation buildings, where the bowls are arranged in batteries.
- As shown upon the drawings, the bowl comprises a suitable base a upon which the structure is supported and which formsan integral part thereof. A hopper or basin 6 is in the front part ofthe structure, and is provided with the usual elliptical flushing rim 0 which forms the annular duct 0 by means of 'whichthe wateris discharged down the interior walls of the basin or hopper through apertures c A water seal is provided, by means of the outlet 11 from the bottom of the hopper, which extends first upward, downward, forward, and then downward, to form a siphon,
nular flange d projecting downward fromthe middle of the base a.
portion of the structure, extendin per, themaj or portion of the neck being above the planeof the flushing rim 0. This neck is divided by a curved partition wall g (see Fig. 5) into two ducts of which the lower one storage room, and obviate the necessity of the end of the duct being encircled by an an- I A cylindrical neck g projects from the rear upward and rearward in the median line 0 the hop- ICC g is circular and the upper one 9 is crescentshown in Fig. 2.
Ordinarily, the normal level of the water in the bowl is very much lowered by the siphonic action, rendering the closet susceptible to back-pressure and loss of seal, so that by providing the retarding chamber, the duct or et supplies suflicient water, after the bowl is flushed, to restore the proper Water level.
The walls I) bof the bowl are swelled out- 'wardly in the rear of the hopper to form two ducts or trunks i i of large cross-sectional area which communicate directly with the duct (1 (see Figs. 3 and 4.) I
The mouths of the trunks i i are below the flushing rims, and are large enough to permit a thorough ventilation of the bowl, and the removal of all malodorous air and gas. The
inner walls of the trunks are formed by the crown of the trap, so that the said ducts or trunks pass around the trap, and the Whole structure is compact and strong.
It will be observed from an examination of Figs, 3 and 5 that the duct 9 is located entirely above the top of the bowl or the flushing rim, and thereby a very undesirable feature of many closets is obviated. Heretofore, the clogging of the soil pi e or the trap with foreign matter has caused the overflow water to pass intothe vent pipe or flue with injurious results, before the condition of the closet was discovered, whereas, by the pres- 'entconstruction and arrangement of parts, the Water overflows on the floor and immediately. makes known the fact that the clpset is clogged and isnot operating propor y.
The entire structure is preferably constructed of vitreous porcelain and is durable and capable of receiving hard usage.
The top of the closet, in the rear of the flushingrim, is flat being formed with later- "-al,ly projecting perforated lugs to receive the seat fittings, while the front portion of the bowl is braced by a strut j which projects upward from the base a.'
In Figs. 1 and 2, we have illustrated the neck g, as projected through a wall lc into a ventilating flue, with a portion of the flushing pipe connected by a cou ling with the duct g, which as illustrate in Fig. 3, is
' equipped with provisions for receiving it.v
Having thus explained the nature of the invention, and described a way of constructing and using the same, though without attempting to set forth all of the orms in which itmay be made, or allof the modes of its use, we declare'that what we claim is 1. A water closet bowl having a water supply duct, a ventilating duct, and a neck through which both of said ducts extend, the ventilatin duct being located above the plane of t e top of the bowl and the terminals of the two ducts being in the same vertical plane, substantially as described.
2. A water closet bowl having a hopper,.a flushing chamber located in the rear of the hopper, two ventilating ducts leading from each side of the rear median line of said hopper, and meeting above said flushing chamer, and above the plane of the top of the hopper and passageways leading into said ducts tor supplying waterand conducting away air and gas. I
3. A water-closet bowl having a neck terml nating in a horizontal portion, said neck being partitioned substantially its entire 7 length to form two passageways, of which one is substantially circular and the other is substantially tion, a ventilating duct communicating with one of said passageways, and a flushing duct communicating with the other of said passageways.
4. A siphon-jet water closet having a rearwardly extending siphonic trap, a ventilating duct extending around the trap, a flushing chamber supported by the crown of the trap, and a rearwardly extending centrally located neck having a passageway communicating with the flushing chamber and a passageway communicating with the bowl, both said passa eways terminating at the end of said neck.
11 testimony whereof I have affixed my signature, in presence of two witnesses.
GEORGE W. KNAPP.
