Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of Lincoln's Inn, in the County of Middlesex, Gentleman, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster; the Twenty-second day of October, in the eighth year of Her
reign, did; for Herself, Her heirs and successors, give and grant unto me, the
said Moses Poole, Her especial licence, full power, sole privilege and
authority, that I, the said Moses Poole, my exors, adiñors, and assigns, or
such others' as I, the said Moses Poole, my exors, admors, or assigns, should
at any time agree with; 'and no others, from time to time. and at, all, times
during the term of years therein expressed, should and lawfully might make,
use,.
exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, the Invention of "IMPROVEMENTS IN MACHINERY FOR EMPTYING
PRIVIES AND CESSPOOLS," communicated to me by a certain Foreigner residing
abroad; in which said: Letters Patent is contained a proviso that. I, the
said Moses Poole, shall cause a particular description of the nature of the
said "Invention, and in what manner the same is to be performed, to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, may more
fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being bad to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
With all machines that have heretofore been used for the purpose of
emptying privies and such like places the objection has been that they have
not been able to prevent the offensive odour from escaping during the
operation, which is not only prejudicial to those in the house where the
operation is performed, but also to the adjoining neighbourhood. Now the
object of these improvements is, the arrangement of machinery in such manner
that the process of emptying privies and such like places may be performed
without the offensive odour escaping; but, in order that the Invention may
be fully understood, I will proceed to describe the Drawings, which shew the
machine applied as it would be when being used for the purpose of emptying

page_text: teeth formed on the rollers which hold the chain to which the cups are
attached so as to prevent them from sliding.. I prefer to have these different
parts of this upper drum. cast together. H is another drum having no pro-
jecting teeth. I is a guide wheel for the chain. m is a support for the same.
n, the bearing of this wheel. o, the drum; and p, the axis. HI' is a guide
roller for the chain, placed at the bottom of the apparatus moving on an axis
at q. r is the drum placed thereon. L, L, are the cups. M is the receiver,
which is shewn by red dotted lines, into which cups L deliver the matter
raised. y, y, are the tubes through which the matters pass from the receiver
to the vessel; they may be used either together or separately. z is a covering
for either of these tubes, which may or may not be employed; in the Drawing
it is shewn on the left tube which is not in use. N is a flexible tube leading
to the vessel into which the matter is to be conveyed, and is the part joined to
the tube of the receiver for the purpose of increasing the length of the tube N.
N¹ is a valve for opening or closing the communication with the vessel into
which the matter raised is being conveyed. N is a weight to keep the piece
N in its proper position. O is the vessel into which the matters are conveyed.
P is a jack for the purpose of lengthening or shortening the length of the
endless chain of cups. x is a ratchet wheel. is a click. a is a piece to
which the click is affixed. vis the rack which is joined to the uprights d',
attached to the lower guide wheels. is a plate which supports the axis of
the jack. is the lower part of the rack v. z is an axis which connects the
upper part of the jack to the framing of the machine. The jack is capable of
turning on this axis. The vertical and horizontal jacks are connected together,
as shewn. Qis the horizontal jack; S, the ratchet wheel; T, the click; V',
the toothed part; V, the end. The horizontal jack is joined to the vertical one.
The jack is connected to the framing and turns on an axis, as shewn. S' is a
connecting rod, which may be lengthened as required, according to the depth
or place where the machine is required to be worked. d¹, the lower part of
the rod, which is attached to the lower guide roller. f is the part where the
rods are joined together. Figure 3 shews a section, and Figure 4, an elevation
of an apparatus for disinfecting the vapour of the soil of its noxious odours. As
it passes from the vessel O, instead of passing into the atmosphere. it passes
through the pipe finto an apparatus R, which has a series of zinc plates
perforated with holes. On the surface of these plates is placed hair or other
suitable material, saturated with chloride of lime or other suitable matter,
through which the gas passes to the hollow of the apparatus and escapes
through the pipe c, into the atmosphere in a purified state. This apparatus is

page_text: hermetically closed at the top. x is the perforated plate, and b' represents
the hair or other suitable matter.
The mode of using the apparatus for emptying privies or other places is
as follows: The apparatus being properly fixed to the place required to be
emptied, the handle D is to be turned, which turns the wheel F, and con-
sequently the drum G, which is mounted upon the same axis. Thus the six-
sided roller is put in motion, and the teeth on the surface of which work into
the chain of cups and raise them up, and these cups are by these means
caused to descend to the bottom of the place, and are again brought up filled
with the matter contained therein, and is deposited into the receiver M, from
whence it passes into the vessels O, as will be understood by examining the
Drawings; and the gas arising therefrom will pass in a purified state into the
atmosphere after having passed through the disinfecting apparatus R. It
will be seen that the working. of the apparatus is very simple, and that it may
be arranged according to the depth of the place; also, by the combination of
the horizontal and vertical jacks any required inclination may be given to the
position of the chain of cups. By this arrangement of machinery, cesspools,
wells, and other places requiring emptying may be emptied in an easy and
rapid inanner at a very little cost.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the precise mode herein described for carrying out the same, so long
as the character of the Invention be retained; but what I claim is,-
First, the use of. an. endless chain of cups, with suitable. apparatus for
working the same, for emptying privies and such like places.
Secondly, I claim the mode of disinfecting the méphetic or noxious gas
arising from such matters.
Thirdly, I claim the enclosing the apparatus in such manner as to prevent
the escape of any odour during the operation of emptying privies and other
such places.
And lastly, I claim the arrangement of the horizontal and vertical jacks
to obtain any required inclination of position for the apparatus, as herein
described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Twenty-second day of April, in the year of our
Lord One thousand eight hundred and forty-five.
MOSES (L.s.) POOLE.
