page_text: LETTERS PATENT to Robert Philip Pope, of No. 8, King's Road,
Gray's Inn, in the County of Middlesex, Architect and Surveyor,
for the Invention of "IMPROVEMENTS IN TRAPPING APPARATUS FOR
TRAPPING WATERCLOSETS AND OTHER PLACES TO PREVENT THE PASSAGE OF
EFFLUVIA:"
Sealed the 27th July 1875, and dated the 6th February 1875.
PROVISIONAL SPECIFICATION left by the said Robert Philip Pope
at the Office of the Commissioners of Patents, with his Petition,
on the 6th February 1875.
I, ROBERT PHILIP POPE, of No. 8, King's Road, Gray's Inn, in the
County of Middlesex, Architect and Surveyor, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN TRAPPING APPARATUS
FOR TRAPPING WATERCLOSETS AND OTHER PLACES TO PREVENT THE PASSAGE OF
EFFLUVIA," to be as follows:-
According to my Invention I form the trapping apparatus of one or
more coils of tubing, or of a continuous chamber formed to act as such,
one end of which coil or chamber is formed to revolve in a suitably

page_text: packed neck provided for it near the bottom of the basin, if for a water-
closet, or other part or outlet of other place, whilst the opposite end of
the coil or chamber is formed to revolve in a similar packing in a
passage to the drain or other passage as a conduit of the matters to be
conveyed away. Both ends of the coil or chamber are turned to form
centres or axial lines of the coils.
When required to use the trap thus formed to conduct away matters,
as in the case of deposits from the basin of a watercloset, rotary motion
is given to such trap, and simultaneously a stream of water is allowed
to flow into the basin, by which, if the coil or chamber be caused to
rotate in the direction for conducting them away the matters will be
removed.
This rotary motion may be obtained by winch handle acting by
band and pulleys or wheel work on the neck of the coil or chamber,
or by a lifter and a ratchet and ratchet wheel, or other suitable
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Philip Pope in the Great Seal Patent
Office on the 6th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
PHILIP POPE, of No. 8, King's Road, Gray's Inn, in the County of
Middlesex, Architect and Surveyor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of February, in the year.
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Robert Philip Pope, Her special
license, that I, the said Robert Philip Pope, my executors, adminis-
trators, and assigns, or such others as I, the said Robert Philip
Pope, my executors, administrators, and assigns, should at any

page_text: time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN TRAPPING APPARATUS FOR TRAPPING WATER-
CLOSETS AND OTHER PLACES TO PREVENT THE PASSAGE OF EFFLUVIA," upon the
condition (amongst others) that I, the said Robert Philip Pope, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Philip Pope, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, that is to say:―
According to my Invention I form the trapping apparatus of one or
more coils of tubing, or of a continuous chamber formed to act as such,
one end of which coil or chamber is formed to revolve in a suitably
packed neck provided for it near the bottom of the basin, if for a water-
closet, or other part or outlet of other place, whilst the opposite end of
the coil or chamber is formed to revolve in a similar packing in a
passage to the drain or other passage as a conduit of the matters to be
conveyed away. Both ends of the coil or chamber are turned to form
centres or axial lines of the coils.
: When required to use the trap thus formed to conduct away matters,
as in the case of deposits from the basin of a watercloset, rotary motion
is given to such trap, and simultaneously a stream of water is allowed
to flow into the basin, by which, if the coil or chamber be caused to
rotate in the direction for conducting them away the matters will be
removed.
This rotary motion may be obtained by winch handle acting
by bands and pulleys or wheel work on the neck of the coil or
chamber, or by a lifter and a ratchet and ratchet wheel or other suitable
means.

page_text: But that the Invention may be more fully understood I will, by the
aid of the accompanying Drawings, proceed to describe means pursued
by me in carrying the same into effect.
Figure 1 is a plan view; and Figures 2 and 3, vertical sectional views
taken respectively through the lines A, A, and B, B, of Figure 1, of
apparatus arranged according to my Invention as applied to a water-
.closet.
Figures 4 and 5, 6 and 7, show details of parts of the previous Figures
to a larger scale and in different positions.
In each of the Figures the same letters indicate corresponding parts.
a represents the seat, and 6 the pan of a watercloset; 6¹ is the outlet
from this pan to the trapping means, which consists of a chamber c in
which revolves another chamber d, which together with the coil e are
affixed to the hollow axis or shaft ƒ so as to form a continuous coil to
revolve with the shaft or axis f. The hollow axis f is supported to turn
freely in packings f¹, f³, carried by the opposite ends of the chamber c,
and it is open at one end f¹ to the outlet 6' from the pan b, and at the
other end f to the channel g by which the contents of the pan b, as
carried forward by the coils e, are conducted to the drain or other
channel.
I would here remark that although the axis fis hollow, one end of it
is stopped off from the other end of it, and the liquid and other matters
received into the pan 6 pass from the outlet 6¹ into that end of the axis f
and thence by a passage formed for the purpose into the compart-
ment (1) forming the first portion of the coil, and as the coil with its
cylinder and axis revolves such contents are progressively carried
forward to the respective compartments 2, 3, and 4, from the last of
which they pass into the opposite part of the hollow axis fand out from
the end thereof, and are discharged into the passage g.
The number or extent of the coils may be varied.
Motion is given to the parts for the discharge of the basin or pan after
use of the closet or for other purpose in the following manner:-Upon
one end of the axis fis formed or applied a toothed wheel h, the teeth

page_text: of which are taken into by the teeth of another toothed wheel i affixed
on the spindle 2, on which is also affixed the bevelled pinion 2, the
teeth of which are taken into by the teeth of the bevelled wheel j
affixed on the spindle. These spindles and are supported so as to
be capable of revolving in suitable stationary bearings, as shewn, and to
the upper end of this spindle is applied a winch handle, by which
rotary motion is imparted to that spindle and thence simultaneously to
the spindle and to the parts forming the coils. The section of the
spindle of this winch handle at the arm o is shown in the Figure 8.
It will be seen by reference that the spindle 1 has a projecting piece
or cam, and that in the arm o there is a certain space which must be
traversed by the arm o before motion can be given to the spindle j¹; the
object of this is that the disc n may be lowered and the water service
put in motion before motion is given to the drum or chamber d.
Fig. 9 shews a feather on the spindle ¹ received into the disc n to
control its rotation with, whilst being capable of sliding on the
spindle j¹.
In
In working with apparatus of the kind described for trapping it is
also necessary that provision be made for the supply of water at each
operation, equivalent to that removed. An arrangement adapted to this
purpose, as arranged by me, consists of a water chamber k, which is
kept supplied by ball tap or otherwise from any suitable source.
the bottom of this chamber is applied a passage ³ communicating with
the pan b, and this passage is opened or closed by means of the valve /
which is operated for this purpose by the weighted end of the lever m
which is supported to turn on the fixed axis m³, and at its shorter end
bears on the under side of the disc n. This disc n is formed with a hole
through it for the passage of the spindle j³, and is connected by pins
with one end of each of the links n³, the opposite ends of which are con-
>nected by like pins to the ends of the arms or bar o affixed to the
spindle. When the crank handle j³ is in a state of rest the disc n lies
up against the under side of the arms or bar o, and the valve / remains
closed, as indicated by Figures 4 and 5; but when the crank handle is
set in motion for the operation of the parts, as stated, the links n¹ will
3 immediately assume a nearly vertical position and the plate n will be
forced downwards from the bar o, as indicated by Figures 6 and 7; the
shorter end of the lever m will be instantly depressed, opening the valve,

page_text: but so soon as any motion to the handle ceases, whether by the com-
pletion of its rotation or otherwise, the pressure exerted by the weighted
end of the lever m will cause the shorter end thereof to bear the plate n
upwards, when the valve / will be instantly closed.
The form of these parts and the means of giving motion to them, as
well as the method of effecting the necessary supply of water to the
pan may be varied, and arrangements of coils or a coiled chamber of the
character described may be applied to operate in drawing off or con-
ducting away various deposits and other matters in other places.
Having thus described my Invention, and means which I adopt in
carrying the same into effect, I would have it understood that I do not
confine myself to the precise arrangements of parts, as shewn and
described, as the same may be varied without departing from the
peculiar character of the Invention; but what I do claim is the
arranging or combining parts forming trapping apparatus for trapping
waterclosets and other places to prevent the passage of effluvia, as
described.
In witness whereof, I, the said Robert Philip Pope, have here-
unto set my hand and seal, this Sixth day of August, in the
year of our Lord One thousand eight hundred and seventy-
five.
