A New or Improved Stench Trap.

page_text: A New or Improved Stench Trap.
1, FREDERICK AUGUSTUS BATES of 13 Isaac Street, Oxford Street, Regent
Road, Salford, Mechanic, do hereby declare the nature of my said invention to be
as follows:-
My invention has for its object to prevent bad smells entering a dwelling house
through sinks and drain pipes, and consists essentially of an attachable trap or valve
capable of being readily attached or applied to the outlet end of a drain pipe.
Said trap consists, by preference of a flat faced disc of metal, hinged to a spring
clamp or yoke, which fitting on the pipe end, causes said valve by its weight and
gravity to automatically cover up or close the end of the pipe.
This valve is so poised and weighted that it will readily allow the drain water
to pass out of the pipe, and immediately come to its seating again as soon as the
water ceases to flow, and thus prevents any stench or smell passing up the pipe
into the house.
For ensuring of its more perfect seating, the disc side of the valve is covered or
provided with a disc of leather or indiarubber, and the end of the pipe is cut or filed
off at a slight angle, the valve being hung to correspond.
The fixing of the clamp on the pipe is, by preference effected by a screw and
wing nut, or wing headed screw with the valve suspended therefrom, but the
elasticity of the clamp may be sufficient to hold it on, or a separate spring may
be employed.
In cases where the pipe end is too short to receive the clamp I provide a small
bracket, fixed to the wall immediately above the pipe, and provided with a hook, on
which the valve aforesaid may be hung to operate upon the pipe end, or for pipes
of large dimensions I may attach the valve to a spring collar or ring, capable when
compressed of being placed in the bore of the pipe, and on being released of
expanding and locking itself therein.
To allow of a greater difference in the diameters of the pipe ends the clamp may
be semi-circular, with a long set screw at one side screwing against the side of the
pipe end, and with a book or claw to hold any size of valve.
Instead of the valve closing on to the pipe end by its own gravity, it may be
arranged to close under the action of a spring, or balance weight.

page_text: I, FREDERICK AGUSTUS BATES of 13 Isaac Street, Oxford Street, Regent
Road, Salford, Mechanic, do hereby declare the nature of my said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
My invention has for its object to prevent bad smells entering a dwelling
house through sinks and drain pipes, and consists essentially of a trap or valve
capable of being readily attached or applied to the outlet end of a sink or drain
pipe. Said trap consists, by preference of a flat faced disc of metal, hinged to a
spring clamp or yoke, which fitting on to the pipe end, causes said valve by its
weight and gravity to automatically cover up or close the end of the pipe.
This valve is also so poised and weighted that it will readily allow the drain
water to pass out of the pipe, and immediately come to its seating again as soon
as the water ceases to flow, and thus prevent any stench or smell passing up the
pipe into the house.
And in order that my said invention shall be the more readily understood and
carried into practical effect I have hereunto annexed a sheet of drawings and I will
now proceed to describe the same with the assistance of the various figures and letters
of reference marked thereon.
Fig. 1 illustrates in perspective the outlet end of a sink or drain pipe, with the
improved trap or valve applied thereto.
Figs. 2 and 3 illustrate side and front views of the same arrangement.
Fig. 4 illustrates the several parts of my improved stench trap separately.
Figs. 5 to 8 illustrate modifications of my invention.
Fig. 9 illustrates a further application, i.e. where the pipe end lies in wall-pocket
for preventing trap or valve from being knocked off.
(A) designates the pipe end to be closed or operated upon in all the views.
(B) the valve or trap, consisting of a flat plate of metal, with (by preference) a
backing or facing of leather, rubber or other suitable packing (C), for effecting the
more complete sealing of the pipe.
As shewn in Figs. (1) to (4) the said valve (B) is hung from the clamping
screw (C¹) of the clamp or collar (D) which fits on to the pipe as illustrated, and
serves to suspend the plate over the pipe end.
The pipe is (by preference) cut or filed off to a slight angle so that the valve
of its own gravity will keep it closed. This may however be left untouched
and the valve held to its seating (pipe end) as shewn in Fig. (5) by a balance
weight (E).
The clamp or collar (D) may be of spring metal to clamp on to the pipe
without any other fastening. It may also be of half-round form as shewn in
Figs. (6) and (7), to allow of great differences in diameter of pipe ends, and
provided with a set screw (F) to fix it, and a claw or hook (G) to receive the
valve (B).
In cases where the pipe end is too short to receive the clamp (D) I provide a
small bracket (H) (see Fig. (8)) fixed to the wall immediately above the pipe as
shewn and provided with a hook (1) on which the valve is suspended, or I may
apply the valve by a spring collar or ring capable, when compressed, of being
placed in the bore of the pipe and on being released of expanding and fixing itself
therein.
It will be obvious that the aforesaid methods of fixing the valve permits of
its renewability, and of the valve being thrown back for the purpose of the pipe
being cleaned out.

page_text: Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim and desire to secure by Letters Patent is :-
1st. A collar or clamp adapted to fit on to the end of a drain or similar pipe,
carrying a plate, and so adjusted as to cause such plate to lie over the outlet end of
said pipe, as and for the purposes set forth.
2nd. The several combinations of parts and modified arrangements of my invention
shewn respectively in Figs. (5) to (8) and hereinbefore described.
Dated this 9th day of June 1896.
