WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN WATER SUPPLYING AND
DISCHARGING APPARATUS FOR WATERCLOSETS, LAVATORIES, AND THE LIKE"
[A communication from abroad by Jesse Edward Folk, of Brooklyn, New York,
United States of America.]
This Invention comprises a swinging tubular branch or arm, so combined with
the trunk or lower portion of a watercloset basin, tank, lavatory, or other water
receptacle, that when the said tubular arm is placed in an upright position and filled
with water, a practically perfect water trap is- formed; whereas when the said
tubular arm is brought to a nearly or quite horizontal or dependent position, it
provides a passage through which the water and other materials enclosed in the
trunk, tank, or the like water receptacle are freely discharged therefrom. The water-
closet or like apparatus will by these means be provided with an anti-siphon trap,
easily worked and effective in operation.
The aforesaid swinging arm, provided as just explained, to the lower portion of the
water receptacle is arranged in due relation with an outlet pipe, to and through which
the water and other matters discharged through the swinging tubular arm are caused
to pass. There is, moreover, a suitable packing ring interposed between the said
tubular arm and the water receptacle to pack the joint between the said parts, without
interfering with the swinging action or operation of the aforesaid arm.
In order to promote the efficiency of this packing a spring is combined in such
Pine AJI

page_text: relation with the ground or packed joint between the tubular arm and the water
receptacle to which it is attached, that the bearing surface of the arm is pressed
firmly and snugly to its place. There is moreover a valve fitted upon the outer end
of the aforesaid swinging arm, so arranged as to close said outer end when said arm
is brought to its vertical position, as aforesaid, thereby preventing any pressure
which might be exerted in a direction toward the water receptacle from interfering
with the water seat or lute formed in the trap, constituted by the said arm in its
upright position.
}
The tubular swinging arm attached to the water receptacle, as explained
and arranged in due relation with the outlet pipe, is with them enclosed in an
air-tight box or casing, which provides for their protection and for their proper
operation. There is also provided a valve having suitable operating mechanism, and
arranged in such connection with the air-tight box and the swinging arm that the
movement of the latter automatically controls the supply of water to wash out the
water receptacle, and to provide the requisite depth of water within the trap formed
as herein-before explained.
In the said apparatus, furthermore, there is combined with the water inlet a supply
valve constructed to ensure the pressure of the supply water wholly upon the lower
or closing face of the valve while the latter is closed. There is also a supplemental
chamber combined with the valve proper, arranged to act in opposition to the
pressure of the supply water, in order that the air and dead water within said
supplemental chamber, together with the weight of said valve proper, will suffice to
keep the valve closed without the aid of a spring or other additional power;
furthermore, in the supply valve of the apparatus the seat is provided with a grooved
channel or recess, which ensures the more perfect operation of some of the features
herein-before specified; there is also provided a divided valve seat, having an outer
valve seat to close the water passage: to the supplemental chamber, and an inner
valve seat to close the water outlet. The outer valve seat, moreover, is arranged to
close the passage to the supplemental chamber, and the groove or channel is
.moreover provided in the valve seat in such relation with the supply inlet as to
communicate therewith. When the valve is closed this water channel is moreover
interposed between the inner and outer portions of the closing suction surfaces of
the valve seat, and acts to diminish the suction of the valve upon its seat to insure
the more perfect operation of the said valve.
-
The
There is furthermore provided a supply valve constructed and arranged to oppose
while closed the pressure of the supply water within the circumference of the valve
proper to the suction or adhesive hold of the valve proper upon its seat.
Bupply valve is moreover constructed to be automatically operated to permit a
continuous inflow of water while the valve is locked. There is also combined with
the supply valve a locking mechanism, so provided that the valve may be positively
locked when open. The supply valve, moreover, and water receptacle are provided
with suitable intermediate mechanism, and the whole is arranged to maintain the
supply valve open in a fixed position until the water receptacle becomes filled to the
required height. Referring again to the valve proper of the supply valve arrangement,
the said valve proper has its spindle constructed with a shoulder or equivalent device
arranged in due relation with a locking lever serving to secure the most efficient
operation of the said valve proper.
There is also embraced in said apparatus a novel combination of a supply valve,
a locking lever, a valve operating lever actuated from the tubular arm, the whole
combined for joint use and operation. There is moreover provided a float box and
a float in combination with a locking lever and a shouldered spindle provided to
the valve proper, the whole constructed and combined to properly limit the inflow
of water to the water receptacle.
The water receptacle is moreover made of truncated globular form, and constructed
in one piece. There is also provided in connection with the water receptable an
overflow channel arranged in due relation to said receptacle.

page_text: There is also embraced in said apparatus a novel combination of a ground joint
with a bearing or bushing, and a shaft on the axial support of the swinging tubular
arm to provide against leakage of the said tubular arm; also a conical valve
composed of two parts, so constructed and applied as to prevent the regurgitation
5 of gases from the drain pipe sewer or the like back toward the water receptacle.
