Im- PROVEMENTS IN APPARATUS FOR CONDENSING the Vapours of Naptha."
Year: 1873

page_text: LETTERS PATENT to Charles Moseley, of Ardwick, in the City of
Manchester, India-rubber Manufacturer, for the Invention of "“Im-
PROVEMENTS IN APPARATUS FOR CONDENSING the Vapours of Naptha."
PROVEMENTS IN APPARATUS FOR CONDENSING THE VAPOURs of Naptha.”
PROVISIONAL SPECIFICATION left by the said Charles Moseley at the
Office of the Commissioners of Patents, with his Petition, on the
13th March 1873.
I, CHARLES MOSELEY, of Ardwick, in the City of Manchester, India-
rubber Manufacturer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN APPARATUS FOR CONDENSING THE VAPOURS OF
NAPTHA," to be as follows:-
This Invention consists in certain improvements in or additions to
the Invention for which former Letters Patent were granted to me on
the 30th day of May 1872, No. 1637.
In the Specification of the said Patent I described how the air and
vapours of naphtha after passing through the condenser were conveyed
into a cistern in which the condensed vapours of naphtha were intended-

page_text: to accumulate, while the air that was carried off with the vapours was to
escape into the atmosphere; now in practice it is found that a great
proportion of the vapours of naphtha instead of being condensed escape
into the atmosphere with the air, and the object and effect of my present
Invention is to prevent the escape of the uncondensed naphtha vapours,
and I accomplish this by causing the vapour current after leaving the
condensor to pass through a number of wire gauze partitions fixed at
intervals in a tube or cistern which is kept partially filled with liquid
naphtha, so that contact is formed between the body of naptha and the
vapour.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Moseley in the Great Seal Patent Office
on the 11th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
MOSELEY, of Ardwick, in the City of Manchester, India-rubber Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Charles Moseley, Her special
licence that I, the said Charles Moseley, my executors, administrators,
and assigns, or such others as I, the said Charles Moseley, my executors,
administrators, and assigns, should at any 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
APPARATUS FOR CONDENSING THE VAPOURS OF NAPHTHA," upon the condition
(amongst others) that I, the said Charles Moseley, 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.

page_text: NOW KNOW YE, that I, the said Charles Moseley, 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 (that is to say) :-
This Invention consists in certain improvements in or additions to
the Invention for which former Letters Patent where granted to me on
the Thirtieth day of May, One thousand eight hundred and seventy-two,
Number 1637.
In the Specification of the said Patent I describe how the air and
vapours of naphtha after passing through the condensor were conveyed
into a cistern in which the condensed vapours of naphtha were intended
to accumulate, while the air that was carried off with the vapours was
to escape into the atmosphere; now in practice it is found that a great
proportion of the vapours of naphtha instead of being condensed escape
into the atmosphere with the air, and the object and effect of my present
Invention, is to prevent the escape of the naphtha vapours, and I accom-
plish this by causing the naphtha vapours and air to pass through any
convenient number of wire gauze sieves or perforated plates in passing
from the condensor to the cistern.
And in order that my Invention may be fully understood and readily
carried into operation I will proceed to describe the accompanying
Drawing which represents a section of my improved apparatus for con-
densing the vapours of naphtha.
f is the end of the condensor described in the Specification of Letters
Patent granted to me on the Thirtieth day of May, One thousand
eight hundred and seventy-two, Number 1637, and f' is the branch
pipe through which the condensed naphtha and the uncondensed
naphtha vapour mixed with air escape from the condensor; the
branch pipe f¹ is connected to the elbow pipe 9', which is in com-
munication with the lower end of the zig-zag tube h¹ in which are
the sieves or perforated plates j; the upper end of the tube his con-
nected to the vertical pipe h² which is carried down to near the bottom
of the cistern g in which are also placed a set of sieves or perforated
plates k. In the cistern g is the overflow tap h, the discharge tap h³, and
the pipe i, for the escape of the air, and the non-condensible vapours
that are carried through the condensor. The sieves are perforated
plates in the zig-zag tube h¹ are placed at a certain distance apart, and

page_text: the naphtha vapours in travelling from the condensor to the cistern
must pass through all the perforations in the said sieves or plates, the
effect of which is to unite and collect those particles of vapour that
remained disconnected when discharged from the condensor; these col-
lected particles of condensed vapour trickle down the sides of the zig-zag
tube h¹ and accumulate in the elbow pipe 9', from which they are drawn
off by the tap 93. The uncollected vapours descending the pipe ³ into
the cistern 9 are in the same manner intercepted by the sieves or per-
forated plates k, and by the body of liquid naphtha in the cistern so
that nothing but air and non-condensible vapour escape through the 1
off pipe i.
Having thus stated the nature of my Invention and described a con-
venient apparatus for carrying the same into operation, I wish it to be
understood that I do not intend to limit myself to the form of the
apparatus shewn and described as it may be considerably varied or 1
modified, but what I claim is causing the naphtha vapours and air
escaping from the condensor to pass through wire gauze sieves or
perforated plates and through a body of naphtha, for the purpose
described.
In witness whereof, I, the said Charles Moseley, have hereto set 2
hand and

described.
In witness whereof, I, the said Charles Moseley, have hereto set 2
my hand and seal, this Sixth day of September One thousand
eight hundred and seventy-three.
