RECEPTACLE FOR WATER-CLOSET OR URINAL PURPOSES.
SPECIFICATION forming part of Letters Patent No. 581,801, dated January 1, 1895.
Application filed November 16, 1893. Serial No. 491,166. (No model.)
' lower edge of the wall d forms the seal, and
To all whom it may concern/.-
Be it known that I, SAMUEL WVALKER LEWIS, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Water- Closets or Urinals, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to receptacles known as siphon-jet water closets and urinals, the object being to prevent the noise when in action, caused by the unchecked rush and es cape of air and water through the rim outlet of the bowl, (as set forth in my prior patent,
No. 509,319, dated November 21, 1893,) and to maintain a quick, powerful siphon discharge with an economical use of water. I attain these objects by the combination of a supply conduit which carries all its contents first directly to an outlet discharging a jet of water, a branching or divided conduit delivery leading from and beyond said jet discharge to a second jet outlet and the rim flushing means, and a siphon discharge outlet having means formed in the outlet passage to accelerate the siphonic action, one of said jets being directed into the long down leg of said siphon, and the other jet being directed into the short up leg of said siphon outlet.
The novelty of my invention will be hereinafter set forth, and specifically pointed out in the claims.
In the accompanyingdrawings Figure 1, is an external view in side elevation of a closet bowl, showing asupply conduit pipe leading first directly to a jet. Fig. 2, is a reverse view of the same showing the course of the branching conduits leading from said jet to a second jet and also to the rim flushing means of the bowl. Fig. 3,isacentral vertical section showing details of construction. Fig. 4, is a (front View) cross vertical section of Fig. 3, on the line cc-m. Fig. 5, is a (rear View) cross verical section of Fig. 3, on theline y-y. Fig. 6, is a plan of Fig. 3.
The same letters of reference are used to indicate identical parts in all the views.
A is the receptacle or bowl with a flushing rim a, and sloping sides or walls terminating in a central outlet into a siphon H, I. The
the bend of the siphon at It forms the weir that maintains the normal level of water in the bowl. H is the short leg of the siphon and l is its long down leg preferably terminating in the basin VV'which is formed by the weir .9, beyond which is the discharge outlet J.
O is the supply conduit, suitably connected with the tank outlet or other source of supply at K, and leading directly to the jet outlet or nozzle ewhich discharges a jet upward into the short leg H of the siphon. Leading from and beyond the jet outlet or nozzle 6 the conduit D divides into two branches, the branch D leading to a second jet outlet at c, which discharges down into the long leg of the siphon and is capped atf, and the branch B B B leading to the rim flushing means of the receptacle at b.
The rim conduit branches downward at B and coils at B before turning upward toward the rim, so that any air from the supply conduit or flush pipe which might escape beyond the jet 6 may pass up the branch D to the second jet and be prevented by the laws of gravity from escaping downward at B. This construction also creates a friction resistance or back pressure in the conduit B which results in a greater jet force and a more gentle flushing of the upper part of the bowl through the rim, as described in my said prior patent.
In Fig. 2, the down leg of the siphon is formed with the usual angular outlet i J so that in operation the outflowing liquid will be retarded and back up to the level i and thus fill the lower end of the down leg to produce the siphonic action. In this form it will be observed the fluid has to back or fill up the full diameter of the horizontal part of the siphon, which requires a large discharge of water-into the receptacle and through the jets.
In Fig. 3, the weir s is preferably just below the level of the angle 2', whereby in action the air in the siphon I may be quickly expelled through the space If, as shown in Fig. 5, before the Water rises to the level i. From this construction it will be apparent, that the surface of the water in the basin W is normally so near the limb t that a very small quantity of water falling from the weir h and jet outlet 0 will instantly expel the air from the siphon and raise the water in the basin W up to the level t', when the vacuum within the siphon I and atmospheric pressure without will produce a powerful siphonic action. At the same time the arrangements of jet and rim conduits will direct all the air in the supply or flush pipes through the jet outlet and cause a gentle flushing of the upper part of the receptacle through the rim or.
If desired the weir s can be raised so the water in the basin W will normally form a seal at 2', in which case, a portion of the water in said basin would have to be displaced in expelling the air from the siphon, which would cause more resistance to the quick action of the device. Hence I prefer to make it with the slight space t formed between the levels i and s as shown in Figs. 3 and 5.
The construction could also be modified by connecting the supply conduit, suitably trapped if desired, first directly to the down turned jet 0, with a conduit leading from and beyond said jet to the upturned jet 6, and a branch conduit leading from said second jet 6 to the rim as at B b.
It will be observed that the three conduits or water passages O D and B form a trap, the connectingloop of which is wholly beneath the bowl or receptacle and in communication therewith through the jet 6, whereby the level of watr and depth of seal in all of said pas: sages is known and indicated by the visible supply of water in the bowl. This feature together with the formation of said passages wholly on the outside of the apparatus is of great value and advantage, as it cheapens and simplifies the construction, and exposes any slight defect that might otherwise be hid den and unobserved if said passages were not so thoroughly exposed. Furthermore the principal jet at 0 being directed into the long leg of the siphon, the jet at e might be reduced or form only a means of coinmunication between the bowl and the trap or loop formed underneath the bowl by the conduits O, D, and B. Hence I do not limit myinveni vention to the precise form of construction shown in the drawings, as it is evident similar modifications will accomplish like results, provided the supply conduit leads first directly to the jet flushing means before discharging into the rim flushing means.
Having thus fully described my invention, I claiml. A receptacle for Water closet and urinal purposes, having both jet and rim flushing means, a supply conduit which leads first directly to an outlet discharging a jet, a second conduit leading from and beyond said jet outlet to a second jet outlet and a third conduit branching from said second conduit below the adjacent part thereof and leading to the rim flushing means, whereby any air contained in said supply conduit is carried to the jet flushing means, one of said jets discharging into the long leg of said siphon, and the other jet discharging into the short leg of the siphon, substantially as and for the purpose described.
2. A receptacle for water closet and urinal purposes, having both jet and rim flushing means, a supply conduit or connection leading first directly to an outlet discharging a jet, a second conduit leading from and beyond said jet outlet to a second jet outlet and a third conduit branching from said second conduit below the adjacent part thereof and leading to the rim flushing means, whereby any air in said supply conduit can escape through said jet outlets, both of said jets discharging into said siphon and the connecting loop of said cgnduits forming a trap beneath the receptacle and in communication therewith, whereby all three conduits or passages are water sealed and the level of water and depth of seal in all of them is indicated and known by the visible supply of water in the bowl of the receptacle, substantially as set forth.
3. A receptacle for water closet and urinal purposes having a rim flushing means, a jet flushing means, and a siphon outlet, a supply conduit leading down under the bowl of the receptacle and up to an outlet discharging a jet into the long down leg of said siphon,the loop forming the trap of said supply conduit having an opening in communication with said receptacle, and a water sealed conduit branching from said supply conduit below the adjacent part thereof and leading from and beyond said jet outlet to the rim flushing means, whereby any air in the supply pipe can first reach and escape through the jet flushing means, and the water seal in all of said passages will be indicated by the water surface in the bowl, substantially as described and set forth. a
4. A receptacle for water closet and urinal purposes, having a rim flushing means, a jet flushing means, and a siphon outlet, a supply conduit leading first directly to ajet discharging upward into the short leg of said siphon, a conduit leading from and beyond saidsubmerged jet to a jetdischarging into the long leg of said siphon, and a third conduit branching from the under side of said second conduit and leading to the rim flushing means,
