Year: 1872

page_text: LETTERS PATENT to Millington Henry Synge, of the United Service
Club, Pall Mall, in the County of Middlesex, Colonel, Royal
Engineers, for the Invention of "IMPROVEMENTS IN DEODORIZING
APPARATUS."
PROVISIONAL SPECIFICATION left by the said Millington Henry Synge
.
at the Office of the Commissioners of Patents, with his Petition,
on the 25th July 1872.
I, MILLINGTON HENRY SYNGE, of the United Service Club, Pall
Mall, in the County of Middlesex, Colonel, Royal Engineers, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN DEODORIZING
APPARATUS," to be as follows: -
This Invention relates mainly to the employment of a rocking vessel
which forms the receptacle for the focal and other matters deposited in
the deodorizing apparatus, and which being charged with dry absorbent
material, such as charcoal dust, earth ashes, or sawdust, will by its
rocking action completely cover and deodorize the focal deposits, and
will also permit of the instantaneous discharge of the same from time to

page_text: time into a receptacle which may be removed without interrupting the
use of the apparatus. This rocking vessel I mount on trunnions at a
suitable distance below the closet seat, and I rock the vessel through
the agency of a pull-up handle and rock levers, or a rack and pinion, or
equivalent mechanism. A raised chamber at the back of the seat is used
for the reception of the charcoal dust, and a shute from this chamber
will guide the charcoal down into the rocking vessel.
The discharge of the charcoal may be controlled by a valve worked
by the pull-up handle, or when the apparatus is adapted for schools,
barracks, or hospitals the valve may be under the control of a responsible
attendant who will open it to discharge a given supply of charcoal into
the rocking vessel and then close and secure it by a lock and key to
prevent the waste of the charcoal. In this case the pull-up handle when
used will simply rock the vessel containing the focal matters and cause
them to combine with the dry absorbent material contained in the vessel.
This rocking vessel may be made of any desired proportions that will
allow of the accumulation of deposits therein during three, six, twelve,
or more hours.
The removal of the accumulated matters from this vessel will be
instantly effected by turning it upside down and shooting its contents
into a receptacle placed below to receive the same. This may be done
by applying to one of the trunnions a winch handle, which is to be
removed so soon as the discharge has been effected, and immediately on
the return of the rocking vessel to its normal position; the apparatus will
then be fit for use, the vessel being recharged by the attendant or by the
automatic apparatus with a fresh supply of the dry absorbent material.
In some cases in lieu of the winch handle the pull-up handle may be
used to overturn the rocking vessel and return it to its normal position.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MILLINGTON
HENRY SYNGE, of the United Service Club, Pall Mall, in the County of
Middlesex, Colonel, Royal Engineers, send greeting.

the apparatus. A chamber raised above the seat is used for the reception
of the granulated charcoal, and a shute from this chamber will guide the
charcoal down into the rocking vessel.
The discharge of the charcoal may be controlled when the apparatus
is adapted to schools, barracks, or hospitals by a responsible attendant,
who will open valves to discharge a given supply of charcoal into the
several rocking vessels, and then close and secure the valves by a lock
and key to prevent the waste of charcoal.
In Sheet I. of the accompanying Drawings Fig. 1 is a front elevation
of the improved apparatus, the seat to which it is applied being shewn
in section; Fig. 2 is a side view of the apparatus; and Fig. 3 is a plán
view of the same.
A is the rocking vessel, fitted at its closed ends with trunnions which
have their bearings in the side pieces of a trunk B, fixed immediately
below the seat C. This vessel is by preference cylindrical, the upper
side being cut away for the admission of the focal and deodorant
matters. At the side of the seat C, and raised above it, is a chamber D
for containing the charcoal or other deodorant. This chamber contracts
at bottom to the width of a shute E, which leads into the trunk B, and
is intended to discharge charcoal into the rocking vessel A. which closes
the trunk at bottom. The chamber D is separated from the shute E by
means of a slide F, which may be secured in its closed position by means
of a hasp and padlock, as shewn at Fig. 2. One of the trunnions of the
vessel A is fitted with a crank arm G, which derives a reciprocating
motion from the rod of the pull-up handle H in the following manner :-
h is a pin projecting from the side of the rod H, and overlying this pin
is an arm of a bell crank lever I, which has its fulcrum on a bracket
piece I', made fast to the trunk B. The other arm of the bell crank
lever is connected by a link K to the crank arm G of the vessel A. As
therefore the pull-up handle is raised the pin h will strike against the
bell crank lever I, and rocking it will cause it to impart a rocking motion
to the vessel A and agitate the contents of that vessel.
To prepare the apparatus for use the vessel must be charged some two
or three inches deep with granulated charcoal, or other dry deodorizer,
from the chamber D, and after each discharge of focal matter on to the

page_text: contents.
The rocking vessel A may be made of any desired proportions that
will allow of the accumulation of deposits therein during three, six,
twelve, or more hours.
The removal of the accumulated matters from this vessel will be
instantly effected by turning it upside down and shooting its contents
into a receptacle provided below to receive the same. To permit of this
movement taking place the arm of the bell crank I overlying the pin h
of the pull-up handle rod is made sufficiently short to allow of its
vibrating past that pin when the pull-up handle is in its normal or
depressed position. By applying to the squared end of one of the
trunnions of the rocking vessel a winch handle, as shewn at Fig. 2, the
vessel may be turned over and its contents discharged with facility into
a receptacle below. On the restoration of the rocking vessel to its
normal position and the removal of the winch handle the apparatus will
require recharging by the attendant with a fresh supply of the dry
absorbent material, and it will then be again fit for use.
The receptacle for the discharged contents of the vessel A. is not shewn
in the Drawing, but it may be either a drawer or removable box, or it
may be a pit or tank in case the apparatus is adapted for schools or
barracks.
The Figures in Sheet II. represent a modification of the above
described deodorizing apparatus. In this example the rocking vessel
is made shallow, and so arranged as to discharge its contents after each
deposit of focal matters.
I have shewn also in connection with the rocking vessel an arrange-
ment of mechanism for supplying automatically the vessel with a fresh
charge of charcoal or other deodorant after every tipping of the vessel,
according to the plan secured to me by Patent, dated August Twenty-
second One thousand eight hundred and seventy-two.
Fig. 4 is a sectional side elevation of the apparatus taken in the
line 1, 2, of Fig. 5, which Figure represents the apparatus in front
sectional elevation.
In these Figures A is the rocking vessel, taking the shape of a shallow
pan. It is fitted with trunnions which have their bearings in metal

page_text: straps made fast to the trunk B, which trunk depends from the seat C,
and is so shaped as to allow of the vessel A. rocking into the dotted
position of Fig. 5. D is the charcoal or deodorant chamber, fitted at
bottom with a casing E, which is formed to receive a rotating measuring
wheel F, and which terminates in a shute E¹ by which the deodorant is
delivered from the wheel F, and is guided on to the pan A. The pan is
rocked by the pull-up handle H, the cranked rod of which is formed
with a lug, through which the curved arm of a bell crank lever I slides.
This bell crank lever communicates motion through a link K. to the
crank arm G fixed to one of the trunnions of the pan A. As therefore
the handle H is raised to the dotted position of Fig. 4 the bell-crank
lever I will be rocked and caused to tip the pan A into the dotted
position of Fig. 5. When the handle is allowed to fall the pan will
return to its normal position ready to receive a charge of charcoal from
the chamber D. To ensure the delivery of this, charge automatically the
rotary measuring wheel F is provided, and it is actuated by the fall of
the pull-up handle rod.
The measuring wheel is formed with compartments or chambers for
receiving the charcoal from the chamber D. In this instance the wheel
is made with four compartments, but a greater or lesser number may be
provided as found desirable. Keyed to one end of the axle of this wheel
is a ratchet wheelf of four teeth, which is worked by a pawle h jointed
to the pull-up handle rod H. As the handle is raised the pawle will be
caused to slide over the ratchet wheel, but as the handle descends the
pawle will engage with one of the ratchet teeth and pull round the
wheel F a quarter of a rotation. To provide a stop for the wheel Fand
prevent its moving by its own impetus I furnish the pawle with a
finger h', which every time that the pawle completes its action will drop
in front of a projection on a cam-shaped disc f¹, keyed to the axle of
the wheel F, thus preventing the further rotation of that wheel.
Having now set forth the nature of my Invention of improvements
in deodorizing apparatus, and explained the manner of carrying the
same into effect, I wish it to be understood that under the above in part
recited Letters Patent I claim,―
First. The use of a rocking vessel for receiving focal deposits and
deodorizing materials, and discharging the same, in the manner and for
the purpose above set forth.

page_text: Secondly. The means above described for operating the rocking vessel
and causing it to discharge the deposits accumulated therein.
In witness whereof, I, the said Millington Henry Synge, have
hereunto set my hand and seal, the Twenty-second day of
January, in the year of our Lord One thousand eight hundred
and seventy-three.
