IMPROVEMENTS IN MACHINES FOR DRYING FIBROUS AND OTHER MATERIALS
Year: 1886

page_text: I, JOHN H. LORIMER, of Philadelphia; Pennsylvania-U.S.A. Manufacturer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN MACHINES FOR
DRYING FIBROUS AND OTHER MATERIALS" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention has reference to drying machines for drying cotton, or other textile
fibre or material &c and consists of two or more large cylinders perforated on their
peripheries and through which dry steam, steam heated or dry air or gas is forced,
and about which cylinders the cotton, yarns &c are caused to pass being pressed in
contact with the surface of said cylinders by suitable bands or aprons; further in
combination of the said cylinders and the guiding bands or aprons the same being
so arranged that the cotton, yarns &c have one surface brought in contact with one
cylinder and the opposite surface brought in contact with or next to the other
cylinder so that in passing around the said cylinders it is thoroughly dried; and
in many details of construction all of which are fully set forth in the following
specification and shown in the accompanying drawings which form part thereof.
The object of this invention is to provide means by which wool, cotton &c either
in the raw or prepared state may be treated and thoroughly dried and in a manner
by which the capacity of a drying machine is greatly increased. By the method
hereinafter described the cotton or wool is put under a forced drying operation as
the steam or drying agent is forced or drawn through the body of the said cotton,
wool &c carrying off the vapors or moisture contained in the said materials,. While
steam heated air is preferable as the drying agent, it is nevertheless to be understood
that a hot gas may be used in lieu thereof, and it is possible even to produce the
same result in a certain degree by forcing cold air through the said cotton or
wool &c as it will carry off the vapor in somewhat the same manner as above
described, but I prefer to use the hot gas, dried air or steam.

embodying my improvements.

A is the frame of the machine. B B¹ are two large drying cylinders forined
with solid heads C and perforated peripheries having coverings E which may be
formed by wire or stamped sheet metal and this cylinder is supported upon an
axle D made hollow having apertures & through which the steam, hot or dry air
or gas may pass to the interior of the drying cylinders and from thence through
the perforation of the periphery or inclosing surface of the same. F is a steam or
air supply pipe and connects with the hollow axles D through the agency of a
stuffing box fand air &c supply to or from said cylinders is regulated by valves G.
In place of forcing the drying medium through the cylinders and substance to be
dried, it may be drawn or sucked through.
L represents the end of a scouring or dyeing machine and the cotton, wool or
yarn fed therefrom is received between the aprons or bands H and I which are
guided over rollers J in the mauner shown, the said bands passing around the
cylinders B in the same direction so that the band or apron I is next to tho
cylinders B and the band H brought next to the cylinder B' the object of which is
to present the cotton, wool, yarns &c on one surface or face adjacent to one cylinder
and the other surface adjacent to the other cylinder when the said cotton, wool &c
is carried about said cylinder for the purpose of being dried. The cotton, wool,
yarns &c after being passed about the cylinders B B¹ in the manner described is
discharged at E in a thoroughly dried condition.
In place of the arrangement of bands or aprons shown in Fig. 1 that shown in
Fig. 3 may be used in which case the apron H works in contact with the
cylinder Bi alone and the apron I with cylinder B. In this case the cotton,
wool &c may pass around the cylinder B B¹ in direct contact therewith, the
particular arrangement of the said feeding aprons of bands being immaterial to my
invention provided that they carry the cotton, wool &c in contact with said cylinders
and cause it to be reversed in passing about the said cylinders as hereinbefore
specified. It is desirable that these aprons or bands be made of open net work,
or they may be made of slats coupled together the object being to allow the steam
heated air or gas a free passageway from the interior of the drying cylinders
through the cotton, wool &c and the conveying aprons. This machine is suitable
for drying vegetable matters as well as fibres and may be used for various purposes
the operation being the same.
While I prefer the construction shown I do not limit myself thereto as the
details thereof may be modified in various ways without departing from my
invention.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is:-
1st. In a drying machine for wool, cotton &c two or more large hollow cylinders
having perforated peripheries through which a drying medium is forced or drawn
in combination with endless feed or conveying aprons of open or net work passing
around said cylinders in opposite directions for the purpose of presenting each side
of the cotton or wool to the said cylinders in succession.
2nd. In a drying machine for wool, cotton &c two or more large hollow cylinders
having perforated peripheries through which a drying medium is forced or drawn
in combination with two endless feed or conveying aprons formed of open net
work or having passages through them and passing around said cylinders in
opposite directions one of which bands is adjacent to one cylinder and the other of
which is adjacent to the other cylinder for the purpose of presenting each side of
the cotton or wool to the said cylinders in succession.
3rd. In a drying machine for wool, cotton &c two or more large hollow cylinders
having perforated peripheries through which a drying medium is forced or drawn
in combination with endless feed or conveying aprons of open or net work passing
around said cylinders in opposite directions for the purpose of presenting each
side of the cotton or wool to the said cylinders in succession and pipes to admit

page_text: the drying medium to or from said cylinders, and valves to regulate its admittance
thereto.
4th. In a drying machine two or more large drying cylinders 'baving perforated
peripheries and rotating in opposite directions in combination with conveying
aprons or bands of open or net work to carry the material to be dried and press it
in contact with said drying cylinders.
5th. The combination of cylinders B B¹ having perforated peripheries E, with
conveying bands or aprons H I, of open work and guide rolls J.
6th. The combination of cylinders B B having perforated peripheries E, and
drying medium supply pipe F with conveying aprons or bands H I, of open work
and guide rolls J.
