IMPROVEMENTS IN STOVES FOR SINGEING HOGS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I WALTER ALFRED BARLOW of 6 St. Pauls Churchyard in the City of London
Patent Agent and Engineer do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STOVES FOR SINGEING HOGS" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This Invention relates to certain improvements upon Letters Patent N° 206
A.D. 1882 for continuous stoves for singeing hogs' carrasses and has for its object
to improve the action and efficiency of such stoves. The singeing room of the
stove, is according to this Invention formed circular, oval or curved in consequence
of which the carcasses while passing through the stove are more uniformly and on
all side acted upon by the fire gases than heretofore.
The carcasses after having passed through the stove are passed out through the
same door by which they have been introduced into the stove. This door is
double winged both parts being suspended by means of levers to the roof, or other
convenient part of the structure or building.
These levers are fulcrumed to the door as well as to the roof or other part of the
structure and allow of the easy opening and closing of the door as the wings are
swinging on the levers aforesaid.
Through the upper part of the singeing room is passed a rail or bar curved or
screw like and entering as well as leaving the stove through openings of the door.
On this rail the carcasses are suspended on bars and rollers and passed into and
through the stove, leaving the latter at a lower level than that of entrance. This
fall of the rail will be sufficient to allow the suspended carcasses to roll by their
suspenders upon the rail through the stove without further. assistance. . Stoppers
arranged above the rail and moved by levers or other mechanical arrangement
from outside the stove, are employed to arrest from time to time the run of the
carcasses and to expose the same more or less to the flame and heating gases of the
fires which latter are arranged at different parts of the circular or oval stove.
The Invention will be clearly understood with reference to the accompanying
Sheet of Drawings of which Fig. 1, represents a longitudinal section of the improved
stove at line a, b, c; Fig. 2, is a longitudinal section at line d, e; Fig. 3 is a front
view of the stove with the door closed; Fig. 4 is a cross section at line f, g, and
Fig. 5 is a ground plan. A, designates the singeing compartment of the stove which
is formed circular in this case, as will be seen from Figs. 4 and 5 of the Drawings,

page_text: Through this space the carcasses are run on a rail i laid in a curved inclined plane
and said rail is for the sake of keeping the same cool connected with a water
tank B concentric with the curve of the stove and rail i. The carcasses are
suspended to the rail by means of iron cross-bars and rollers m, as will be seen
from Fig. 2 and are presented in front of the stove at the higher level of the rail
and they are discharged from the stove at the lower level of the rail. Each
time when door T is opened, a new carcass is fed into the stove at l whilst a singed
carcass is removed from the stove at same time at . The furnaces or fire-grates F
are placed near the bottom of the stove and arranged at different parts of the
circumference of the stove. p p are inspection holes for observation of the process
of Bingeing.
The water box B will be furnished with valve for exit of steam and may be
provided with connections for circulating water therethrough.
The door T is formed of two parts or wings each of which is suspended by two
pendulating levers 88 which parts can by chains or other convenient mechanical
-arrangement simultaneously be opened or closed. A uniform and rapid opening
and closing of the door wings is required as otherwise the loss of heat would
be too great and furthermore the effective working of the stove is thereby
enhanced.
The run of the different carcasses inside the stove is arrested by bars or stoppers r
which stop the motion of rollers m when lowered by levers H in which position the
-bottom-end-of-the corresponding bar 7 arrives in front-of-the-roller_m_and_prevents
the same from moving. As soon as the bars are lifted the rollers-become-free..and.
begin to run forward to the next stopping bar which has been relowered in the
meantime. The lifting and lowering of the stoppers is executed by the workman
Burveying the process of singeing through the inspection holes p p.
Each-time-the-stoppers are lifted the door. Tis.opened at same time to allow
the carcass in front to leave the stove at whilst at same time n-new-carcass-is
entered into the stove at t. The ends of rail-i-are prolongated outside the stove.
_and_the_carcasses removed from the stove are run along the rail to other parts of
the building where they are further treated-as-required..
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
In stoves for continuous singeing of hogs'-carcasses :—
Firstly. The arrangement of the singeing compartment A of circular oval or
curved shape so that the carcasses exit through the same door by which they are
introduced to the stove substantially as herein specified.
Secondly. The door T for entrance and removal of the carcasses into and from
the stove as herein set forth and shown by the Drawings.
Thirdly. The suspension of the doorwings in pendulating supports for the
purpose of rapid and easy motion of the parts as herein set forth and shown by
the Drawings.
Fourthly. The curved inclined rail i following the circular or curved form of the
singeing room substantially as herein set forth and shown by the Drawings.
Fifthly. The curved inclined shape of the water tank B to which rail i is secured
for the purpose of cooling the same as herein specified.
