when the rod 15 is rotated through a suf-
ficient angle to move the extremity of the
pin 17 to the lower portion of the surface
18, it is obvious that said rod will be dis-
5 placed forwardly, bringing the valve 14 into
contact with the discharge outlet and closing
the latter.
Upon the exterior of the casing a lever 20
is mounted fast upon the extremity of the
10 rod 15. When this lever is in the position
indicated by the dotted lines in Fig. 1, the
pin 17 carried by the rod 15 will be deflect-.
ed downwardly contacting with the lower
portion of the inclined surface 18, and hold-
15 ing the valve 14 closed. When it is desired to
flush the closet, the lever 20 will be made to
assume the position shown in the full lines
in Fig. 1, a cord 21 being attached to one
extremity of said lever in order that the
20 lever may be readily manipulated. When
the long arm of the lever 20 is drawn down,
causing the valve 14 to open, the lever is
temporarily held in this position by a latch
arm 22 pivoted upon the extremity of the
25 shorter lever arm and adapted to catch upon
a pin 23, when the shorter lever arm is ele-
vated. A spring 24 acts upon the latch
member 22 in order to insure the entrance
of the pin 23 into the latch aperture of the
30 arm 22. The lower extremity of the latch
arm 22 is beveled and when said arm is in
its raised position, this extremity contacts
with the beveled extremity of a pivoted arm
25. This arm occupies a horizontal position
35 when the arm 22 is raised and the valve 14
is open. A cord 26, secured to the extremity
of the ari 25, passes over a small pulley 27
mounted in the wall of the casing, and has
its other extremity attached to an arm 28
40 rigid upon one of the rocker arms 3. A
weight 29 is suspended from the extremity
of the short arm of the lever 20. This
weight causes the lever 20 to return to its
position indicated in dotted lines, when the
45 latch arm 22 is released from the pin 23.
The manner of releasing this latch arm will
be specifically described hereinafter. Upon
the other rocker arm 3 there is rigidly
mounted a small arm. 30 on the exterior of
50 the casing and normally occupying a ver-
tical position. The extremity of this latter
arm is connected by a cord 31 with the up-
per extremity of a centrally pivoted latch
arm 32, which also normally occupies a ver-
55 tical position. A coiled spring 33 tends to
hold the latch arm 32 upright. A lever 34
is mounted adjacent to the latch arm 32 and
is provided with a projecting pin 35, which
is adapted to engage in the latch aperture
60 of said arm 32 when in its normal hori-
zontal position. A cord 36 is secured to the
lever 34 adjacent to the pin 35 said cord
passing through eye screws 37 under the
casing 2 and down the wall upon which the
65 casing is mounted. The cord 36 finally hasits extremity attached to the rim of a small
sheave 38 rigidly mounted upon a valve rod
39. The rod 39 operates a valve 40 and a
spring 41 coiled upon said rod tends to nor-
mally hold the same closed. 70
In the operation of the invention when it
is desired to flush the closet 10 the lever
arms 20 and 34 are both manually changed
from the positions shown in the dotted lines
in Figs. 1 and 2 to the positions shown in 75
the full lines. This causes both the valves
14 and 40 to be opened, and permits water
to be discharged into the inlet chamber 11.
From this chamber the water will flow out
through the aperture 12 into the vessel 1. 80
When the vessel 1 is full, the weight of the
water will cause it to turn over discharging
into the reservoir 8 after which the weight
5 will cause it to return to its normal posi-
tion. When the vessel 1 turns over, the arm 85
28 and the cord 36 will act together to swing
the arm 25 upon its pivotal support. This
motion of the arm 25 will force the latch'
arm 22 outwardly causing the pin 23 to be
released from the latch aperture and per- 90
mitting the lever 20 to undergo an angular
deflection due to the weight 29, the arm 22
being simultaneously lowered and the valve
14 being closed. As the vessel 1 turns over,
the arm 30 is deflected similarly to the arm 95
28. This causes the latch lever 32 to swing
about its support and release the pivoted
lever 35. This lever then resumes a vertical
position as indicated by dotted line in Fig.
2, and the valve 40 is instantly closed, due 100
to the action of the spring 41 upon the
valve rod 39. When the vessel 1 returns to
its normal upright position, the coiled
spring 33 will cause the latch lever 32 to
again become vertical. It is thus apparent 105
that the pipe 13 is normally closed at two
separate points completely preventing the
escape of any water from said pipe. The
advantage of this is that in case the water
in the pipe 13 should freeze, causing said 110
pipe to burst at any point above the floor,
the amount of water escaping from said
pipe would not be greater than that con-
tained therein above the floor, since the
closed valve 40 would prevent further flow. 115
If desired, however, the valve 40 might be
disconnected and its accompanying mecha-
nism might be dispensed with using only
the valve 14 with its mechanism, or vice
versa. These two arrangements for clos- 120
ing the pipe 13 may be considered as modi-
fications of the same invention.
What I claim is:
In a device of the character described, the
combination with a pivotally mounted ves- 125
sel, of a casing within which the same is
mounted, having a reservoir in its lower
portion provided with a discharge outlet,
means by which the vessel is deflected
slightly from the vertical in its normal posi- 130
