IMPROVEMENTS IN DEODORIZING APPARATUS
Year: 1872

page_text: LETTERS PATENT to Millington Henry Synge, of the United Service
Club, Pall Mall, in the County of Middlesex, Colonel Royal Engi-
neers, 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 10th September 1872.
I, MILLINGTON HENRY SYNGE, of the United Service Club, Pall Mall,
in County of Middlesex, Colonel Royal Engineers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN DEODORIZING Apparatus,”
to be as follows:—
The object of this Invention is to discharge measured quantities of
charcoal dust or other pulverized deodorant into a pit or series of recep-
tacles for excrement and at the same time to prevent the discharge
apparatus from being tampered with.
Supposing it to be intended to apply the Invention to a row of seats
or closets in connection with barracks or workshops I provide an elevated

page_text: 番
box at the back of each seat, and I 'lead down therefrom a discharge
spout which will guide the descending charcoal into the pit or receptacle
below. In each of these spouts I fit a pair of slide valves, one valve
being below the other and at such a distance apart that the space
between them shall contain charcoal sufficient for one discharge. The
upper valves of the series I connect with a horizontal sliding rod, which
is jointed to one arm of a rock lever, and the lower valves I connect to
a similar sliding rod, which is jointed to another arm of the same rock
lever. This rock lever I mount in a place which is accessible only to
the latrine attendant, whose duty it will be at suitable intervals to set
the rock lever in action by a pull or push rod, or its equivalent, and
thereby to discharge on to the focal deposits a measured supply of the
deodorant. The rods through which the valves are actuated will be
covered so as to protect them from being tampered with by the occu-
pants of the seats.
In some cases I may connect the pairs of valves together in small
groups or attach them to independent rods so as to allow of one pair or
a group being actuated independently of the remainder of the series.
The valves may also if thought desirable be made to swing instead of
slide to provide for the supply and discharge of a measured quantity of
the deodorant.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Millington Henry Synge in the Great Seal Patent
Office on the 10th March 1873.
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.
WHEREAS Her most Excellent, Majesty Queen Victoria, by her
Letters Patent, bearing date the Tenth day of September, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Millington Henry Synge, Her special licence
that I, the said Millington Henry Synge, my executors, administrators,
and assigns, or such others as T, the said Millington Henry Synge, my

page_text: executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thercafter 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 DEODORIZING
APPARATUS," upon the condition (amongst others) that I, the said Milling-
ton Henry Synge, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Millington Henry Synge, 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, reference being had to the Drawings here-
unto annexed, and to the letters and figures marked thereon (that is to
say):
The object of this Invention is to discharge limited quantities of
granulated charcoal or other dry deodorant into a pit or a series of
receptacles for excrement by means of apparatus that cannot be tampered
with.
The Invention is intended to apply mainly to rows of seats or closets
connected with barracks or workshops, and to prevent the wasteful and
wanton use of the deodorant. To this end I provide an elevated box at
the back of each seat, and I fit the same with a measuring apparatus
which will be inaccessible to the user of the closet, but under the control
of the latrine attendant, and in connection therewith I further provide
a discharge spout or its equivalent which will guide the descending
charcoal into the pit at a spot immediately below the seat.
In Sheet I. of the accompanying Drawings Fig. 1 shews in front
elevation, partly in section, a portion of a row of closets fitted according
to my Invention; Fig. 2 is a vertical section of the same taken in the
line 1, 2, of Fig. 1; Fig. 3 is a side elevation of one of the end closets;
and Fig. 4 is a plan view shewing three closets side by side.
In these Figures A, A, are the charcoal boxes or chambers, which
severally terminate in a spout B, which is divided longitudinally by a

page_text: partition 6 so as to form two distinct channels for the discharge of the
deodorant. Through the whole series of spouts run a pair of parallel rods
C, C, which are supported in suitable guides. These rods are connected
at one end to a T shaped rock lever D, one arm of which is embraced
by a hand lever E, having its fulcrum at e.
The rods C, C, are provided with sliding valves c constructed by
preference after the manner shewn on an enlarged scale at Figures 5.
These valves slide in guides made in the spouts B.
By reference to Fig. 1 it will be seen that the slide valves are arranged
in pairs, one valve being below the other and at such a distance apart
that the space between the lines of traverse of the two valves shall be
sufficient to contain charcoal for one discharge in each division of the
spout. The rock lever D I mount in a place which is accessible only to
the latrine attendant, whose duty it will be at suitable intervals to set
the rock lever in action by means of the hand lever E. By shifting this
lever from the drawn position of Fig. 3 to the dotted position, and vice
versa, the position of the valves c will be shifted through the action of
the sliding rods C, and thereby a measured discharge of charcoal on to
the focal deposits throughout the series of closets will be simultaneously
effected. The rods C, through which the valves are actuated, it will be
necessary to cover, as shewn in the Drawing, to protect them from being
tampered with by the occupants of the seats.
In some cases I may connect the pairs of valves together in small
groups or attach them to independent rods so as to allow of one pair or
a group being actuated independently of the remainder of the series.
The valves may also if thought desirable be made to swing instead of
slide to provide for the supply and discharge of a measured quantity of
the deodorant. An arrangement of this kind is shewn in Sheet II. as
applied to a range of closets. Fig. 6 is a front elevation partly in
section; Fig. 7 is a vertical section taken in the line 1, 2, of Fig. 6; and
Fig. 8 is a plan view partly in section. The charcoal chamber A is
fitted at bottom with a fixed plate A¹ and with a sliding segment plate C.
This plate A¹ forms the bottom of a swinging frame or measuring box B
when that box is in a position to receive a charge of charcoal from the
chamber A. The swinging box B is carried by a bell crank lever B¹,
having its fulcrum at B³, and the sliding segment plate C is carried by a
pair of arms having their fulcrum at C¹. The tail of the bell-crank

page_text: lever B¹ is connected to a horizontal rod D, which extends to all the
closets of the series, and is similarly in connection with the charcoal
delivery apparatus of each closet. At one end this rod D connects. with
a slotted rock lever E, which has its fulcrum at E', and is provided with
a handle for operating it. In pulling at this handle the attendant will
thrust the rod D forward, and thereby rock the bell cranks B¹ and
advance the measuring boxes B to the dotted position of Fig. 8. In
their advance the boxes will carry forward a measured supply of charcoal
and discharge it into the pit below, and as the boxes leave the plates A¹
the segment plates C will fall and close the bottom of the chambers A.
These segment plates are formed with a projection on their under face,
against which the boxes B on their return to their normal position will
strike and thereby thrust back the segment plate O to the position shewn
at Fig. 7. The hand lever E will be required to be protected by a
padlock and chain or other similar contrivance to prevent the charcoal
or other deodorant from being wastefully used.
In Sheet III. I have shewn a modified arrangement of a swinging
supply valve. which is set in action by the rocking in place of the sliding
of the valve rod. Fig. 9 is a sectional elevation of one of a series of
closets fitted with a swing valve, and Fig. 10 is a sectional elevation.
taken in the line 1, 2, of Fig. 9. In these Figures A is the charcoal
box set above the seat and closed by a swinging valve B, which is made
fast to a rock shaft C extending along the series of closets. This
swinging frame B consists of a curved plate which serves when rocked
into position to close the charcoal box, and of a measuring chamber
formed of radial side and segmental end pieces. When the valve is in
the position shewn at Fig. 10 its measuring chamber will be charged
with charcoal, but as it is swung round to discharge its contents the
curved plate will close the bottom of the charcoal box. A shute is pro-
vided at D to guide the charcoal discharged by the valve on to the focal
deposit. The shaft O is rocked by a hand lever E, as in the last
example, and this lever will in like manner be kept under the sole
control of the latrine attendant.
To provide against the caking of the charcoal and the consequent
choking of the charcoal box I may find it desirable to supply the box

page_text: curved plates G, which carry projecting pins g. The plates are con-
nected to the sides of the box by means of screws which pass through
elongated slots in the plate. This allows of the plates receiving a
reciprocating endway motion, which motion will cause the pins g to
disturb the charcoal and ensure its falling freely. The bottom ends of
the plates rest upon cams H keyed to the rock shaft C, antifriction
rollers being interposed between them, as shewn in the Drawing, if
thought desirable.
It will now be understood that each time the shaft C is rocked to set
the valves in action the plates G will be caused to rise or fall, and 1
thereby effectually to disturb the contents of the charcoal box.
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, placing the deodorant supply valves of a series
of closets under the control of the latrine attendant in the manner and
for the purpose above described.
In witness whereof, I, the said Millington Henry Synge, have here-
unto set my hand and seal, this Eighth day of March, in the
year of our Lord One thousand eight hundred and seventy-
three.
