page_text: I CHARLES HORATIO SHEPHERD of 225 West 23rd Street, New York City, in the
County and State of New York United States of America, Dentist, do hereby declare
the nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
Reference is to be had to the annexed drawings forming a part of this specification
in which―

Figure 4 is a horizontal section taken on the line z-z in Figure 3.
Figure 5 is a vertical transverse section of my improvement, and
Figure 6 is a detail view of the armature lever of the valve attaching mechanism.
Similar letters of reference indicate corresponding parts in all the views.
The object of my invention is to provide an efficient sewerage system, by means of
which the entrance of sewer gas to buildings may be prevented, and by which the
waste pipe of the building may at any time be thoroughly cleaned and disinfected.
My invention consists in a receiver interposed between the waste pipe of a building
and the sewer pipe, for receiving the waste and delivering it to the sewer pipe, and in
devices for rendering the discharge of the sewerage into the receiver intermittent. It
also consists in the arrangement in the receiver, of a broom to be operated from the
outside of the receiver, for stirring up and dislodging the matter accumulated at the
bottom of the receiver. It also further consists in means for flushing the receiver and
applying disinfectants thereto, and in devices for drawing a soil-pipe cleaning brush
through the pipes, for dislodging any matter adhering to the walls or sides of the
LD

page_text: pipes. My invention further consists in a ventilating device, and in electro-magnetic
appliances for releasing the discharge valve of the sewer pipe.
The receiver A may be made of any desired form, but I prefer to make it square (as
shown in the drawing) to facilitate the cleaning operation, and to insure the more
ready discharge into the sewer pipe B placed near one of the corners of the receiver.
The waste pipe (of the building to which my improved system is applied is connected
with the receiver above the centre line thereof, extends into the receiver a short
distance, and is finally bent downward with its mouth parallel with the bottom of the
receiver, as shown in Figure 3. The waste pipe C is provided with a valve Doutsido
of the receiver, and its lower end a is flared and brought to a knife edge.
The valve is pivoted between ears & projecting from the side of the mouth of the
pipe, and is closed by a counter weight c on the lever c² mounted on the pivot of the
valve and provided with an arm which presses the back of the valve E. In the
horizontal portion of the pipe C, within the receiver A, is placed a float lover F
carrying at its free end the float G. The lever F is secured to one end of the shaft d,
the other end of which extends through the side of the pipe C, and is provided with an
arme which is connected by the rod f with a spring catch lever g, secured to the
sido of the mouth of the pipe C, and arranged to hold the valve E closed.
In the angle of the pipe C is formed a hand-hole H³ which opens directly opposite
the horizontal part of the pipe C. Opposite the centre of the pipe C, a windlass I is
secured to the side of the receiver, and provided with a bevel wheel / which receives
motion from the bevel wheel on the shaft I, extending through a stuffing box j in
the wall of the receiver, and carrying a crank J by which the windlass may bo
operated. The windlass I receives a cord k which is designed to be drawn through
the waste pipe through a gland, the end thereof being attached to a cylindrical
brush. The brush is designed to fill the pipe and remove any accumulation from tho
inner surface of the pipe, and the power required to draw the brush through the pipe
is applied to the windlass I by means of the crank J.
Within the receiver A is suspended a broom K by the chain l, which extends
upward over the pulley m supported by the top of the receiver, then obliquely
downward to a cavity n in the wall of the receiver,, the said. cavity being closed. by a
screw. cap. The end of the broom handle o is provided with a socket p which rests
in an opening in the wall of the receiver,, the said opening being closed by the cover q
and when the cover is removed an auxiliary handle may be screwed into the socket,,
for operating the broom. The bottom of the receiver is provided with a concave
diagonal depression r, leading from one end of the receiver to the other, extending
under the pipe C and communicated with the sewer pipe B.
The sewer pipe B is provided with a stop valve L by which it may be closed when it
is desired to flush the receiver, and a water pipe M enters the receiver opposite thic
sewer pipe B and under the waste pipe C. A cord s is connected with the weighted
arm and extends over pulleys to a cavity in the wall of the receiver; the said cavity
being closed by the screw plug t, and a cord u is connected with the spring cap g; and
extends over pulleys to a similar cavity v closed by a screw plug v².
The operation of my improved system is as follows:—
The waste matter accumulates in the pipe C above the valve E until the float is
raised so as to operate the catch g and liberate the valve, when the pipe C is discharged
into the receiver. The weighted lever c¹ attached to the valve E closes the said valve.
as soon as it is relieved of the weight of the matter, and the valve is re-engaged by
the spring catch g, where it is held until the float rises and disengages the spring cap.
The waste matter finds its way by gravity to and through the sower pipe B.
The receiver is occasionally flushed by water introduced' through the pipe M, and
when it is desired to give the receiver a tliorough cleaning the valves 19, L, are closed
and water is admitted to the receiver through the pipe M, to a point about even with
the discharge end of the pipe C; as will be indicated by the glass water gauge N
connected with the side of the receiver. The cover is then removed and the
auxiliary Broom handle is screwed into the sockett p; and the broom is: let down by

page_text: releasing the cord 1, and is worked back and forth over the bottom. of the receiver
until all the matter thereon is loosened. The valve L. is then opened. allowing tho
water to escape, and the receiver is again flushed, and this operation may be repeated.
until the receiver is entirely cleaned. The valve L is then closed, and disinfectants are.
introduced through the hand hole D in the top of the receiver, and these, if desirable,,
may be washed out by water introduced through the flushing pipe M.. When this has
been accomplished the operator enters the receptacle through the packed door land
completes the cleansing of the receiver as may be required.. He opens the hand
hole H, and the cord being carried down through the waste pipe by a suitable
float, the lower end thereof is attached to the windlass I, while the upper end is.
secured to a brush. adapted to slip through the pipe G and reinove all the matter
adhering to the inner surface of the pipe.. The receiver may be provided. with.ant
exterior cover or casing to protect it and improve its appearance..
To perinit of oiling the journals of the float and valve, tubes 1,.2, are. inserted, in
the top of the receiver and connected. with the said journals.
In the modified form of my invention the lever F is secured to, one end. of. tho.
shaft d, the other end of the shaft extending through the side of the pipe C, and
carrying an arm. e which is connected by the rod with the trip lever you the shaft.
journaled' in ears projecting from the edge of the pipe C.
Upon the same shaft g¹ is mounted a catch lever g provided with three arms, 1, 2, 3.
The arm 3 engages the edge of the valve E, the arm I is pressed outward so as to
bring the catch into engagement with the valve by the spring 4, and the arm 2 carries an
armature 5 which is within the influence of the electro-magnet 6 secured to the side
of the receiver A. The rod fis prolonged beyond its connection with the trip lever g
and carries a contact point 7 which is capable of engaging the contact & supported in a
fixed position in the receiver A. When the float G rises (by the accumulation of
water or sewerage in the pipe C) it pushes down the rod f and turns the lever g, bringing
the toe 9 of the said lever into engagement with the arm 3 of the lever g³, thereby
pushing back the said arm and disconnecting it from the valve E; but just previous
to the release of the valve E the contact point 7 touches contact 8, when the current
flows from the battery 10 through the wire 11 to the contact 3, contact point 7, wire 12,
magnet 6 and wire 13 back to the battery, thus completing the electric circuit and
energizing the magnet 6, when the armature 5 will be drawn toward the magnet 6,
assisting the float & in performing its work of releasing the valve E.
In wire 11 is inserted a push button, which may be located in any part of the
building, and by means of which the circuit may at any time be closed so as to
insure the opening of the valve E whether the float G is operative or not.
In some cases where it is desirable to secure the frequent opening of the valve E,
I place the float G in the vertical part of the pipe C, nearer the valve, so that a smaller
accumulation in the pipe will effect the opening of the valve.
In the top of the receiver A is inserted a ventilating pipe 14, which extends to the
top of the building and prevents the accumulation of pressure in the receiver.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :—
