Improvements in Apparatus for Drying and Ageing Spun Cotton or
other Fibres.
I, SAM MASON, junr. of St. Anne's Place, Manchester in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has for its object the construction of a simple and effective apparatus
whereby spun cotton or other fibres can be uniformly and quickly dried or aged in a
continuous manner, and my invention consists principally in the application of an
endless belt, or preferably a chain provided with a number of perforated baskets or
receptacles travelling in a vertical direction inside a suitable chamber or casing, in
which a current of hot or dried air is caused to circulate.
casing near the
In carrying out my invention I moudt within a suitable chamber or
top and bottom thereof respectively a shaft on which I suitably fasten a chain pulley,
over which I place a chain, one of the said pullies being arranged to slide so as to
permit of keeping the endless chain properly expanded, the other receiving a slow
motion by means of worm wheel gear.
Near to the outside of the said chain I attach in pairs at suitable distances apart
from each other a number of arms or brackets supporting a rod near their extremities,
or other suitable means, which facilitates a ready placing on and removal from the
said rods of the aforesaid baskets or receptacles, into which the spun cotton or other
fibres in cops or bobbins, to be dried or aged, are placed vertically and permits the
latter to remain always perpendicular in any position.
The chamber or casing in which the said chain and baskets travel 1 divide into two
vertical compartments and form the same with an air inlet and outlet at the bottom,
so that the hot or dried air suitably created can be constantly circulated through the
said chamber or casing by drawing or forcing it through the same by a fan or fans
or other suitable means.
At the top of the said chamber or casing a suitable opening is formed from where
the condensed vapour can escape when required.
For ageing purposes I employ in addition to the described arrangement, at a
convenient part in the said chamber or casing a table or plates covered with felt
or other fibrous material on or over which I saitably conduct a fine spray of water,
for the purpose of moistening the air in the said chamber or casing.

Improvements in Apparatus for Drying and Ageing Spun Cotton or
other Fibres.
1 SAM MASON, junr. of St. Annes Placo, Manchester, in the County of Lancashire,
Engineer, do hereby declare the nature of this invention, & in what manner the
same is to be performed to be particularly described & ascertained in & by the
following statement :-
My invention has for its object the construction of a simple & effective apparatus
whereby spun cotton or other fibres can be uniformly and quickly dried or aged in a
continuous manner, and my invention consists principally in the application of an
endless belt, or preferably a chain provided with a number of perforated baskets or
receptacles travelling in a vertical direction inside a suitable chamber or casing, in
which a current of hot or dried air is caused to circulate.
And in order that my invention may be more fully understood I have cause to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is an end view, & Fig 2 a side view of the apparatus with its casing or
chamber shown in section.
In carrying out my invention & referring to the figs. generally, I mount within a
suitable chamber or casing a near the top & bottom thereof in suitable bearings b & c
respectively, the shafts & e, on which I suitably fasten the chain pullies f&g, over
which I place a chain or its equivalent, one set of the said pullies &g preferably
the bottom onef. ie. its shaft e is arranged to slide & to be adjusted vortically, so as
to permit of keeping the endless chain or its equivalent properly expanded, the
top pullies & shaft d receiving a slow motion preferably by means of a worm
wheel, gearing into a worm i fixed on the cross shaft provided with a fast & loose
pulley & m.
Near to the outside of the said chains I attach in pairs at suitable distances apart
from each other a number of arms or brackets a supporting a rod o near their
extremities, or other suitable means, which connect the chains together & receive
the perforated baskets or receptacles p, .e. the hook like arms p¹ formed theroon, so
as to facilitate a ready placing on, & removal from the said rods o, i.e. chain h, of the
aforesaid basket or recoptacle p, into which the spun cotton or other fibres in cops or
bobbins, to be dried or aged, are placed vertically & permit the latter to remain
always perpendicular in any position.
P
The chamber or casing in which the said chain & perforated baskets or
receptaclos travel, I divide into two vertical compartments a & a² by means of the
partition & form the same respectively near or at the bottom with an air inlet r
& outlet so that the hot or dried air suitably created can be constantly circulated
through the said chamber or casing a by drawing or forcing it through the same by a
Jan or fans or other su'tible means.

page_text: For instance by passing cold air through a coil or series of pipes exposed to the
fire of a furnuco drawn or forced into and circulated through the chamber or casing a,
in the direction of the arrows, the perforated baskets or receptacles p moving in the
opposite direction.
At the top of the said chamber or casing a a suitable opening 6' is formed from
where the condensed vapour can escape when required, & at a suitable height at the
side thereof, another opening o' to facilitate the removal & replacing of the perforated
baskets or receptacles p, for the purpose of emptying & recharging the same with
spun cotton or other fibres to be dried or aged.
This opening o', if deemed necessary, may be furnished with a sliding or hinged
door or window o³.
For ageing purposes I employ in addition to the doscribed arrangement, at a
convenient part inside the said chamber or casing a, preferably near the top thereof, a
table or plate w covered with felt or other fibrous material, on or over which I conduct
a fino spray of water, created by means of perforated pipes ..
A small open space left all around the plate or table w permits the water to run
from the same against & down on the insides of the chamber or casing a, while the
air in the latter picks it up and thus gets moistened.
The quantity of water entering the pipes may be regulated by means of the
tapy, & the water accumulating at the bottom of the chamber or casing a allowed to
drain off through the opening z formed therein.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
In apparatus for drying or ageing spun cotton or other fibres; the application &
combination of an endless vertically travelling chain h, on the outside of which are
suspended removably, perforated receptacles p, with a chamber or casing a, surrounding
the aforesaid chain & perforated receptacles h & p, having a vertical partition 7, air
inlet & outlet & sin connection with one or more fans, charge & discharge
opening o', & means for damping or moistening the air in the chamber or casing a,
all substantially as & for the purpose set forth.
