PROVISIONAL SPECIFICATION.
Improved Means to be employed in connection with the Freezing
or Chilling of Meat or other Articles.
We EVERARD HESKETH and ALEXANDER MARCET both of 23 St. Swithins
Lane in the City of London, Engineers, do hereby declare the nature of this
invention to be as follows:-
Our invention has for its object to reduce manual labour and handling of the
meat or other articles to be frozen or chilled and to very efficiently economically
and expeditiously effect the freezing or chilling operation.
According to our invention we arrange in line or one after the other the hanging
room, the freezing or chilling room and the bagging or discharging room and along
this series of rooms we mount a carrier by which the meat or other articles can be
carried from and through one room to and through the others. The carrier
preferably consists of an endless chain or chains supported by runners running on
rails near the upper part of the room and provided with hooks or other supports by
which the carcases or other articles can be suspended from or attached to the chain
or chains or carriers which is or are caused to have a slow progressive movement
through the series of rooms which movement may be gained by any suitable means
such as for instance by passing the the chains or carriers over sprocket wheels
driven by any suitable motor. The several rooms may be of any suitable
construction but the freezing or chilling room we prefer to make with hollow walls
between which the cooling medium circulates as described in the Specification of
our Patent No. 6117 of 9th April 1889 although we do not limit ourselves to this
as for instance cold air from any air cooling machine may be passed into the room.
We circulate the cooling medium or pass in the cold air so that it enters at the end
of the room at which the carcases or other articles leave so that the carcases or articles
meet colder and colder air as they move towards the exit of the room.
There may
be doors between the rooms which can be opened by the movement of the carcases
or articles and will close again after they have passed. The carcases from the
slaughter house or other articles are hung upon the hooks or suspenders of the
carriers as they come over into the hanging room where the said carcases or
articles are subjected to the cooling effect of air currents to effect preliminary
cooling. They then pass as the carrier travels forward into the freezing or chilling
room and passing therethrough enter the bagging or delivery room where the
carcases or articles are removed and conveyed to the store or other place which
may be effected by a lift or carrier provided for the purpose of conveying them to
any desired place.

COMPLETE SPECIFICATION.
Improved Means to be employed in connection with the Freezing .
or Chilling of Meat or other Articles.
We EVERARD HESKETH and ALEXANDER MARCET both of 23 St. Swithins
Lane in the City of London England Engineers do hereby declare the nature of
our invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
Our invention has for its object to reduce manual labour and handling of the

page_text: meat or other articles to be frozen or chilled and to very efficiently economically
and expeditiously effect the freezing or chilling operation. According to our
invention we arrange in line, or one after the other, the hanging room, the freezing
or chilling room and the bagging or discharging room and along this series of rooms
we mount a carrier or carriers by which the meat or other articles can be carried
from and through one room to and through the others. The carriers preferably
consist of an endless chain or chains supported by runners running on rails near the
upper part of the room and provided with hooks or other supports by which the
carcases or other articles can be suspended from or attached to the chain, or chains,
or carriers, which is, or are, caused to have a slow progressive, or intermittent,
movement through the series of rooms which movement may be gained by any
suitable means; such as, for instance, by passing the chains, or carriers, over
sprocket wheels driven by any suitable motor. The several rooms may be of any
suitable construction but the freezing or chilling room we prefer to make with
hollow walls between which the cooling medium circulates as described in the
Specification of our British Patent No. 6117 of 9th April 1889 although we do not
limit ourselves to this as for instance cold air from any air cooling machine may
be passed into the room. We circulate the cooling medium, or pass in the cold air,
so that it enters at the end of the room at which the carcases or other articles leave
so that the carcases or articles meet a lower and lower temperature as they move
towards the exit of the room. There may be doors between the rooms which can
be opened by the movement of the carcases or articles and will close again after
they have passed. The carcases from the slaughter house (or other articles) are
hung upon the hooks or suspenders of the carriers as they come over into the
hanging room where the said carcases or articles may be subjected to the cooling
effect of air currents to effect preliminary cooling. They then pass as the carrier
travels forward into the freezing or cooling room and passing therethrough enter
the bagging or delivery rooms where the carcases or articles are removed and
conveyed to the store or other place which may be effected by a lift or carrier
provided for the purpose of conveying them to any desired place.
The accompanying drawings illustrate an arrangement according to this invention
for freezing or chilling operations especially applicable to treating meat but we do
not limit ourselves to the precise details shewn therein.

transverse section of the said arrangement. A is the hanging room B is the
freezing or chilling room and C is the bagging or discharging room. d are sprocket
wheels or pulleys (secured to shaft g) over which pass endless chains E provided

motion imparted to it by the engine H through the band h.
The chains E carry
hooks e and the carcases are hung upon them in the room A and by the movement
of the chains are carried through the freezing or chilling room B between the hollow
walls J through which the cooling medium is passed the said cooling medium being
cooled by the action of the refrigerating machine shewn at K and pumped into a
tank from which a pipe leads to the spaces in the hollow walls J which
communicate with each other preferably in such a way that the cooling medium
passes from one to the other in a direction the reverse of that in which the carcases
travel and then returns to the refrigerators. Instead of circulating brine as described
cold air from a cold air refrigerating machine may be passed into the freezing or
chilling chamber B preferably at the end at which the carcases leave.
closing the openings through which the carcases pass into, and from, the freezing or
chilling room B may be made to swing open as the carcases pass and to close again
when they have passed. M is a lifting arrangement consisting of an endless chain N
passing over sprocket wheels or pulleys n (which may be operated by the engine H)
the said band carrying cradles or hooks or the like as at n into which the carcases
are placed when they are removed from the hooks e and are thereby carried up
into the store rooms P above.
