PROVISIONAL SPECIFICATION.
Improvements in Machines for Drying Brewers' Refuse and other
Materials and Substances.
We, RICHARD CUNLIFFE, of 61, Derby Road, Weaste, Engineer, and HENRY
FORSHAW, of Ford House, Bury Old Road, Manchester, Merchant, both in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in that type of machines for drying
brewers' refuse and other materials and substances requiring similar treatment,
for instance, grain, rice, granulated chemicals, stable, towns' and slaughter-house
refuse and the like wherein a rotary cylinder or retort is employed the object
being to provide means whereby the drying of any kind of material or substance
can be performed on the outer periphery of the cylinder in a very rapid and
thorough manner.
In carrying out our invention we employ as usually in this type of machine
a furnace in connection with a cylinder or retort formed with trunnions, adapted
to rotate inside a casing and be heated, but instead of causing the hot gases
from the furnace to impinge upon the exterior of the cylinder or retort we so
arrange the furnace flues that the hot gases enter the interior and the hot air
passes around the exterior of the cylinder or retort.
The cylinder or retort we form externally with a suitable number of longi-
tudinal blades or buckets and one side of the lower half of the casing concentrically
and the other lower half eccentrically to the axis of the cylinder or retort in
such a manner, that the blades or buckets on the latter, will gradually move in
contact with the casing or nearly so.
The top of one side of the casing we form with a trough in which we employ
a feed worm which extends along the whole length or periphery of the cylinder
or retort. At the inlet end of the machine, a hopper is arranged from which
the material or substance falls upon the feed worm which discharges it at the
opposite end onto the blades or into the buckets of the cylinder or retort. At
the opposite side of the latter we employ a series of inclined plates which extend
along the whole length of the cylinder or retort and casing and are suspended
from the interior of the latter at a point above the centre of the cylinder or retort.
The lower ends of these plates are jointed to a rail which is rendered longi-
tudinally adjustable say by means of a chain and lever whereby the inclination of the
same can be altered at will or the plates rendered inoperative. The material or
substance discharged by the feed worm onto the blades or into the buckets, is
carried by the cylinder or retort about half way round and then thrown upon
the inclined plates from which it falls upon an inclined shelf and from the
latter into the bottom of the casing where it is subjected to the hot air from the
furnace. The material or substance is then caught again by the said blades or
buckets carried round by the cylinder or retort and further deposited upon the
said inclined plates and so on until the latter have propelled it back to the inlet

page_text: end of the machine where it is allowed to drop out of the machine through an
opening in the casing or retort or from whence it may be conveyed by a worm
to the back end of the machine again or by other worms round the back to the
front end of the machine and be discharged at any suitable point of the machine.
It will thus be readily understood that each time the blades or buckets empty
their contents onto the said inclined plates the material under treatment is caused
to travel along the side of the cylinder or retort a distance corresponding with
the degree of inclination at which the plates are set and that by varying the latter
as described the speed at which the material travels. along the cylinder and
thus the period of time during which it remains under treatment may be altered
at will to suit circumstances.
For the drying of slaughter house refuse, hops or the like materials or sub-
stances of a somewhat solid nature, we employ in connection with the feeding
hopper a rotary cage or disintergrater adapted to suitably reduce and feed the
same into the said hopper.
The hot gases enter the said cylinder or retort from the back of the furnace
through a suitably arranged pipe and after having given off heat escape through
a chimney employed at the opposite end of the cylinder or retort.
The casing may be left open or closed at the top as found most suitable and
a chimney formed thereon to carry away the noxious gases resulting from the
drying operation and a pipe may be arranged between the casing and the feed
hopper to convey hot air to the material or substance in the latter and thus pre-
liminary heat the same. By preference we rotate the said cylinder or retort by
means of worm wheel gearing and the said feed and delivery worms by chains
and chain wheels or the like.

Improvements in Machines for Drying Brewers' Refuse and other
Materials and Substances.
We, RICHARD CUNLIFFE, of 61, Derby Road, Weaste, Engineer, and HENRY
FORSHAW, of Ford House, Bury Old Road, Manchester, Merchant, both in the
County of Lancaster, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in that type of machines for drying
brewers' refuse and other materials and substances requiring similar treatment
for instance grain, rice, granulated chemicals, stable, towns' and slaughter-house
refuse and the like wherein a rotary cylinder or retort is employed the object
being to provide means whereby the drying of any kind of material or substance
can be performed on the outer periphery of the cylinder in a very rapid and
thorough manner.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a side view partially in section, and Fig. 2 an end view of our improved
machine.

page_text: In carrying out our invention we employ as usually in this type of machines
a furnace a in connection with a cylinder or retort formed with trunnions c,
adapted to rotate inside a casing a and be heated, but instead of causing the
hot gases from the furnace a to impinge upon the exterior of the cylinder or
retort 6 we so arrange the furnace flues e, f that the hot gases enter the interior
and the hot air passes around the exterior of the cylinder or retort b.
The cylinder or retort b we form externally with a suitable number of longi-
tudinal blades or buckets g and one side of the lower half of the casing & con-
centrically and the other lower half eccentrically to the axis of the cyunder or
retort in such a manner, that the blades or buckets g on the latter will gradually
inove in contact with the casing or nearly so.
The top of one side of the casing d we form with a trough h in which we employ
a feed worm i which extends along the whole length or periphery of the cylinder
or retort b. At the inlet end of the machine, a hopper & is arranged from which
the materials or substance falls upon the feed worm which discharges it at the
opposite end onto the blades or into the buckets g of the cylinder or retort b.
At the opposite side of the latter we employ a series of inclined plates / which
cxtend along the whole length of the cylinder or retort b and casing d and are
suspended from the interior of the latter at a point above the centre of the
cylinder or retort b. The lower ends of these plates are jointed to a rail m which
is rendered longitudinally adjustable, say by means of a chain n and lever o,
whereby the inclination of the same can be altered at will or the plates rendered
inoperative. The material or substance discharged by the feed worm i onto the
blades or into the buckets g is carried by the cylinder or retort b about half way
round and then thrown upon the inclined plates from which it falls upon an
inclined shelf and from the latter into the bottom of the casing d where it
is subjected to the hot air from the furnace. The material or substance is then
caught again by the said blades or buckets g carried round by the cylinder or
retort and further deposited upon the inclined plates and so on until the
latter have propelled it back to the inlet end of the machine where it is allowed
to drop out of the machine through an opening q in the casing d of the cylinder
or retort or from whence it may be conveyed by a worm r again to the back end
of the machine for discharge or by two other worms s, .t round the back to the
front end of the machine where the opening g is provided for the discharge
thereof.
It will thus be readily understood that each time the blades or buckets g empty
their contents onto the inclined plates the material under treatment is caused
to travel along the side of the cylinder or retort a distance corresponding with
the degree of inclination at which the plates are set and that by varying the
latter as described the speed at which the material travels along the cylinder
and thus the period of time during which it remains under treatment may be
altered at will to suit circumstances.
For the drying of slaughter house refuse, hops or the like materials or sub-
stances of a somewhat solid nature, we employ in connection with the feeding
hopper a rotary cage or disintegrater q adapted to suitably reduce and feed
the same into the hopper k.
The hot gases enter the cylinder or retort 6 from the back of the furnace a
through a suitably arranged pipe t' and after having given off heat, escape through
a chimney employed at the opposite end of the cylinder or retort b, whilst
the hot air enters the casing & through pipes s¹ at the side of the latter.
The casing d may be left open, as shown; in full lines or closed at the top, as
shown in dotted lines, as found most suitable and chimney formed thereon
to carry away the noxious gases resulting from the drying operation and a pipe u
may be arranged between the casing d and the feed hopper k to convey hot air
to the material or substance in the latter and thus preliminary heat the same.
By preference we rotate the cylinder or retort 6 by means of worm wheel gearing
and the said feed and delivery worms by chains and chain wheels or the like.

invention and in what manner the same is to be performed we declare that what
we claim is: -
"In machines for drying brewers' refuse and other materials and substances."
