page_text: LETTERS PATENT to John Evatt Acklom, of No. 1, Royal Well
Terrace, Cheltenham, in the County of Gloucester, for the Invention
of "IMPROVEMENTS IN RAILWAY AND OTHER CARRIAGES FOR THE CONVEYANCE
OF ANIMAL AND VEGETABLE SUBSTANCES USED FOR FOOD, WHICH IMPROVEMENTS
ARE ALSO APPLICABLE TO OTHER CHAMBERS FOR THE STORING OF SUCH
SUBSTANCES.'
"
Sealed the 5th September 1873, and dated the 12th March 1878.
PROVISIONAL SPECIFICATION left by the said John Evatt Acklom
at the Office of the Commissionors of Patents, with his Petition,
on the 12th March 1878.
I, JOHN EVATT ACKLOM, of No. 1, Royal Well Terrace, Cheltenham,
in the County of Gloucester, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN RAILWAY AND OTHER CARRIAGES FOR THE
CONVEYANCE OF ANIMAL AND VEGETABLE SUBSTANCES USED FOR FOOD, WHICH I■.
PROVEMENTS ARE ALSO APPLICABLE TO OTHER CHAMBERS FOR THE STORING OF SUCH
SUBSTANCES," to be as follows:
-
In applying my Invention to railway or other carriages a somewhat
funnel-shaped channel is formed at or near the upper part of each end
•

page_text: of the carriage. One of these passages, that at the front end of the
carriage, communicates with another by which the air collected is
conducted down to a chamber extending under the lower surface of tho
carriage, which is there perforated or formed with reticulate work so
that the air conducted thereto may freely pass to the interior of the i
carriage upwards amongst matters supported thereon on openwork trays
or shelves until it reaches the upper part and passes away by the other
funnel. Fans or blowers applied in the chamber under the carriage,
and set in motion by the carriage axles or otherwise, serve to maintain
the current of air.
A reservoir is applied at the upper part of the carriage to contain ico,
the water from which in melting, or other water, is conducted therefrom
through suitable openings in fine streams over matting, felt, or suitable
matter to aid in keeping the interior of the carriage cool. The sides and
other of the parts of the carriage are formed of similar non-conducting
material or other suitable absorbent held between wire trellis, or such
like openwork adapted to absorb the moisture from the reservoir above
and to keep the interior cool. Any liquid formed in the chamber will
be carried away by suitable openings formed for the purpose in the
lower part of it. A similar arrangement is applicable to other chambers
for the storing of animal and vegetable substances used as food, care
being taken that the inlet passage for the air be always turned in the
direction towards the draught, and the outlet away from it. The action
of the fans may also be varied to cause a vacuum in the carriago or
chamber to draw the surrounding external air through the saturated
sides of it to be expelled by the fans through the vontilator or other
outlet.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Evatt Acklom in the Great Seal Patent
Office on the 12th September 1878.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN EVATT
ACкLOM, of No. 1, Royal Well Terraco, Cheltenham, in the County of
Gloucester, send greeting.

One thousand eight hundred and seventy-three, in the thirty-sixth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, tho said John Evatt Acklom, Her special licenso that I, the
said John Evatt Acklom, my executors, administrators, and assigns,
5 or such others as I, the said John Evatt Acklom, 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,
O the Channel Islands, and Isle of Man, an Invention for “IMPROVEMENTS IN
BAILWAY AND OTHER CARRIAGES FOR THE CONVEYANCH OF ANIMAL AND VEGETABLE
SUBSTANCES USED FOR FOOD, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER
CHAMBERS FOR THE STORING OF SUCH SUBSTANCES," upon the condition
(amongst others) that I, the said John Evatt Acklom, my executors
5 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 dato
0 of the said Letters Patent.
NOW KNOW YE, that I, the said John Evatt Acklom, do hereby
declare the nature of the said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
5 In applying my Invention to railway or other carriages a somewhat
funnel-shaped channel is formed at or near the upper part of each end of
the carriage. One of these passages, that at the front end of the
carriage, communicates with another by which the air collected is con-
ducted down to a chamber extending under the lower surface of the
O carriage, which is thero perforated or formed with reticulate work so
that the air conducted thereto may freely pass to the interior of the
carriago upwards amongst matters +upported thereon on openwork trays
or shelves until it reaches the upper part and passes away by the other
funnel. Fans or blowers applied in the chamber under the carriage, and
5 set in motion by the carriage axles or otherwise, serve to maintain the
current of air.
A reservoir is annlied at the unner part of the carrince to contain ine

page_text: the water from which in melting, or other water, is conducted therefrom
through suitable openings in fine streams over matting, felt, or suitable
matter to aid in keeping the interior of the carriago cool. The sides and
other of the parts of the carriage are formed of similar non-conducting
material or other suitable absorbent held between wire trellis or such
like openwork adapted to absorb the moisture from the reservoir above,
and to keep the interior cool. Any liquid formed in the chamber will
be carried away by suitable openings formed for the purpose in the lower
part of it. Similar arrangements are also applicable to other chambers
or "safes" for the storing of animal and vegetablo substances used as
food, care being taken that the inlet passage for the air be always
turned in the direction towards the draught, and the outlet away from
it. The action of the fans may also be varied to cause a vacuum in the
carriage or chamber to draw the surrounding external air through the
saturated sides of it to be expelled by the fans through the ventilator or
other outlet.
In applying my Invention to butchers' carts and other carts for the
conveyance of animal or vegetable substance which it is desirable to
keep cool, especially in hot weather, I form the body of the cart "closed,"
and with admission to the interior for general convenience by a closely 1
fitting door at the back, and I form a considerable portion of the sides,
front, and back, as well as the door by pannels capable of ready removal
or application, and these pannels are composed of frames to the inner
and outer surfaces of which are applied perforated zinc or other open-
work, and in the space between these surfaces of openwork to cach frame :
I apply a surface or a series of surfaces of thick felt, flannel, or other
substance adapted to receive and hold water, and at the same time to
act as a non-conductor of heat; and when in use I cither by a small
reservoir above or otherwise keep these felt or such like surfaces
constantly wet. I also form the upper part of the cart with an opening
or a passago in the direction of its longth, and truncated at the front ond
of it to act in producing a current of air to carry off any vapour gene-
rated within the body of the cart. The interior of the cart is provided
with rails, hooks, or shelves as may be found most convenient for the
support of the animal or vegetable substances to be conveyed.
Having thus described my Invention, I would havo it understood that

page_text: other carriages and other chambers may be kept cool for the better con-
veyance or storing of animal or vegetable substances, substantially as
described.
In witness whereof, I, the said John Evatt Acklom, have hereunto
set my hand and scal, this Ninth day of September, in the year
of our Lord One thousand eight hundred and seventy-three.
JOHN EVATT ACKLOM. (L.s.)
