- I WATER CLOSET Filed Sept. 50, 1955 Beam INVENTOR ATTO RNEY Patented Sept. 6, 1938 UNITED STATES WATER CLOSET James R. Beam, New Castle, Pa., assignor to Universal Sanitary Manufacturing 00., New Castle, Pa., a corporation of Pennsylvania Application September so, 1935, Serial No. 42,966
1 Claim.
Under the conventional practice of starting siphonic action in water closets by means of a jet, the degree to which the jet is effective is dependent on the amount and velocity of water delivered to the jet less the friction resulting from flowing through the jet. Smooth channels having few turns are factors determining the velocity of the jet water, and it is the object of the present invention to provide a closet construction in which the water is delivered to the jet in a most direct manner, so that friction losses, which would otherwise lessen the velocity, are reduced to a minimum. Further, it is an object to provide a closet construction in which the rim jets perform only the wash-down function and in which the water, after delivery to the closet, is divided, a part passing to the rim and the remainder to the jet. .Additionally, it is an object of the invention to provide a closet construction of the kind indicated, which is of simple form and, therefore, susceptible of cheap manufacture.
With this object in View, the invention consists in a construction and combination of parts, of which a preferred embodiment is illustrated in the accompanying drawing, wherein:
Figure 1 is a central vertical sectional View of a closet constructed in accordance with the invention.
Figures 2, 3 and 4 are sectional views on the planes indicated by the lines 2-2, 3-3 and 44 respectively of Figure 1.
In the present invention the jet I0 is disposed in the well II in facing relation to the intake I2 of the trap of the closet and the flush water is delivered to it from the intake chamber I 3, which is disposed above the trap, whose globular formation where the up and down legs connect forms the bottom of the chamber. A jet chamber I4 is formed in the Well of the closet and this chamber is in communication with the intake chamber I3 through channels or ducts I5 that may be secured either through drain casting or the insertion of clay partitions, but which are preferably secured by the superficial application of tubular conductors laid on the sides of the closet and incorporated with the latter by filling in around them before the closet is placed in the kiln. The conductors I 5 communicate with the intake chamber I3 on opposite sides. Either one conductor I5 placed on one side of the closet may be employed or the conductor may be duplicated on the other side, as shown, in which case the flush water leaves the chamber I3 at similarly positioned points on opposite sides and in like manner enters the jet chamber I4.
When the flush tank is attached, the chamber I3 becomes inaccessible, but in each flushing of the closet, the chamber I3 is practically emptied, except for such water as may be trapped in the rear portion I6. The freezing of such trapped water, however, will not be attended with any injury to the closet, since the walls of the chamber I5 at the section I6 are generally divergent and, therefore, are relieved of any direct pressure by the forming ice.
Since the conductors I5, after application, become integral parts of the closet, the glazing operation results in complete concealment of them, as the filling in around the conductors prior to the glazing gives a general contour pleasing to the eye.
The superficial application of the conductors makes possible a placing of the intake and jet chambers in communication through ducts or channels that are free of slight projections that would constitute obstructions interfering with the free flow of the jet water and, therefore, reduce the Velocity at which it is delivered to the jet.
The jet I0 is of generally oval form. This results in quick movement of the dead water in the up-leg of the trap and, therefore, in quick starting of siphonic action.
The Wash-down function is accomplished by means of water delivered to the channel I! formed in the rim I8, this channel being in communication with the intake chamber I3 through a port or opening' I9. The rim 'on the under-side is formed with a series of spaced ports 20 which communicate with the channel IT. The ports 20 are downwardly inclined toward the inner face of the bowl and are likewise inclined downwardly toward the left, considering the rim as being viewed from the top. In other words, the axes of the ports 20 are arranged to follow left-hand spirals in the surface of an imaginary cone, so that the water issuing through them will be given a left-hand swirl, thereby intensifying the natural water swirl in this latitude, which is left-handed.
In the flushing operation, when Water is admitted to the entrance chamber I3 from the flush tank, one part passes through the port I9 to the channel ll of the rim and the other part to the jet chamber I4, from which it issues in the form of a crescent shaped jet and passes into the upleg of the trap. The amounts of water delivered respectively to the rim channel and the jet chamber are determined by the proper proportions of the conductors I5. If there be two of such conductors applied, one on each side of the closet, as shown, the capacity of each for a given quantity of water need be only half that necessary to be provided where only one is used.
The jet, being in facing relation to the up-leg of the siphon, is above the level of the bottom of the wall and the ducts 15, at every point, in their lengths are above the level of the well bottom. Thus the jet water does not have to move a great body of still water in starting the siphonic action, the arrangement being such that the jet has only to start movement of the water in the up-leg of the siphon. This construction also provides for complete removal of the water when draining the closet, without having to take it from concealed chambers. A siphon tube placed in the bottom of the well, by removing the water at that point, will completely remove all of the contained water, or the water may be removed readily by mopping it up.
Having described the invention, what is claimed as new and useful is:
A water closet bowl having a trap with its intake in the well thereof, a jet disposed in the well in facing relation to the intake of the trap but above the plane of the bottom of the well, and a water intake chamber disposed on top of the trap and on the opposite side of the bowl from the jet but above the plane of the latter, the bowl having ducts incorporated therewith to place the intake chamber in communication with the trap, the ducts extending around the bowl from the chamber to the jet at a gradual inclination with no points in their lengths being below the plane of the jet.
