IMPROVEMENTS IN COTTON AND WOOL DRYING MACHINES
Year: 1885

page_text: I, JOHN H. LORIMER, of Philadelphia, Pennsylvania, U.S.A, Manufacturer, do
hereby declare the nature of my invention for "IMPROVEMENTS IN COTTON AND
WOOL DRYING MACHINES," 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 wool, cotton, yarns, &c.; and
consists essentially in endless aprons of suitable construction which are guided over
rollers, and combined with a hot air chamber which may be heated in any suitable
manner, for the purpose of carrying the material to be dried, be it wool, raw or
prepared, or wool, cotton, or any kind of yarn in skeins or warp through a hot
atmosphere and by which the material 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 dry in as quick a time as possible freshly dyed
or scoured wool, cotton, in the raw or prepared condition, and perform the manipu-
lation in a continuous manner.
In the Drawings :-
Fig. 1 is a sectional elevation of a drying machine embodying my invention.
Fig. 2 is an elevation of a modified arrangement of heating apparatus.
Fig. 3 is a plan view, and
Fig. 4 is a cross section of one form of apron.
A B are two endless aprons between which the wool or cotton to be dried' is held
and conveyed through the dryer or hot air chamber, and may be formed of link
chains with slats between, or webbing, netting, or combinations of any two or
more of these may be used, the particular construction of these endless conveyors
or aprons being immaterial to my invention.
These aprons A B lie close upon each other in passing through the heating or
drying chamber H, and while passing around and over the guide rollers G G¹,
moving back and forth, or up and down through said chamber for the purpose of
being retained therein as long a time as necessary. The apron A is guided outside
the chamber H by rollers K, and apron B by rollers E E¹.

page_text: D is the feeding table and may be of any suitable construction, and the yarns,
wool or cotton to be dried after being fed upon the apron B is carried up over
rollers F and between it and the apron A which passes around roller K, and enters
the drying chamber H through opening hand while held between the aprons, and
if desired prevented from displacement by slats C thereon, is conveyed over
rollers G G and after passing back and forth a number of times, emerges by
apertures h¹ and passing up over rollers e is delivered from between the aprons A B
at L, the said aprons returning over the rollers K E¹.
The travelling aprons may be made as shown in Fig. 3, in which M M are two
chains or bands connected by slats N to which the netting or webbing O is secured.
The slats are preferably on top of the net work or next to the cotton, wool,
yarn &c. to be dried, so as to prevent the same from being displaced on turning
over the drums or pullies in transit through the heating apparatus. The netting
may be formed of cord or twine or their equivalent, and if desired the slats N
may have teeth or projections N¹ to more securely hold the material to be dried
from displacement.
If desired the yarns, wool, &c. may be washed or scoured in a machine such as
illustrated in American Letters Patent, granted to me October 14th. 1884, and
No. 306, 695, and from which the cotton, wool, or yarns in skein or warp may be
delivered to the feeding table D or directly to the endless aprons and conveyed
through the drying chamber, and it is also evident that the yarns so cleansed and
dried may be fed automatically to a dying machine indicated by dotted lines at the
other end of the drying apparatus, or if desired the dying machine may deliver
the yarns, &c. to the aprons at the feeding end, and they may be dried by passing
through the chamber Ĥ.
This drying chamber H may be simply a large chamber in to or through which
hot air or gas is forced or drawn by a blower or fan J, or by any other means, the
ingress or egress of air being allowed by the openings h'h¹, or if required by any
suitable openings as at I.
In place of heating the chamber H by hot air or gases as above set forth, the
same result may be effected by causing the endless aprons to pass around hot air or
steam pipes as indicated in Fig. 2, but I do not limit myself to any particular
method of heating the said chamber, and it might be remarked that if the steam
pipes be used, the addition of the chamber H might be done away with, as it
would not be necessary to confine the hot air.
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. The combination of two endless aprons and guiding rollers for same so
* arranged as to hold them together between the feeding and delivery ends, and to
separate them to receive and discharge the material at these ends, with beating
or drying apparatus over or through which the said aprons pass while passing from
the feeding to the delivery ends.
2nd. The combination of two endless aprons with guide rollers to support said
aprons and convey them back and forth within a chamber or drying room.
3rd. The combination of two endless aprons with guide rollers to support said
aprons and convey them back and forth within a chamber or drying room, and
a feeding table arranged at one end and adapted to feed the good to be dried
between the aprons.
4th. The combination of two endless aprons with guide rollers to support said
aprons and convey them back and forth within a chamber or drying room, and a
scouring or dying machine located at one or both ends.
5th. The combination of endless aprons A B, guide rollers GQ, drying chamber H,
and means substantially as described to heat the same.
6th. The combination of aprons A. B, rollers GG, K, E E¹, chamber H having
apertures h h³, and means substantially as set forth to heat the said chamber.

page_text: 7th. The combination of endless aprons A B, with guide rollers G G³, EE, K,
and heating mechanism substantially as described through or over which said
aprons are passed.
8th. The combination of endless aprons A B, formed of netting O, slats N, and
chains or bands M, substantially as set forth in combination with heating apparatus
over or through which said aprons are caused to pass while being held close
together.
