PROVISIONAL SPECIFICATION.
An Improved Drying Machine for Paper or other Materials.
I, JOSEPH ARNOLD, Paper Manufacturer, of Eynsford Paper Works, Eynsford,
in the County of Kent, do hereby declare the nature of this invention to be as
follows:-
In my improved drying machine I have a series of trays, or other suitable
vehicles, for holding and conveying the material to be dried. These trays are
suspended between two or more rows of metal or other endless chains or ropes,
passing around and driven by wheels or pulleys at each end, and at the top and
bottom of the machine, and so guided by other wheels and pulleys as to traverse
internally the entire length and height of the machine. The trays, chains or ropes,
wheels, and pulleys, are enclosed in an iron framework which serves to carry them,
and to afford fixing for the necessary driving apparatus.
The whole of the arrangement is closed in on all sides and above, either by suitable
non-conducting material, or by being placed in a close brick or other chamber,.
two small mings only being left to permit the passage inwards of the chains or
ropes with the trays laden with damp material, and of the chains or ropos travelling:
outwards with the trays laden with dried material.
•
Applied towards the top of the chamber containing the machine, I have an
oxhaust fan, so arranged as to remove the moisture as it is ovolved from the
material, an adequate supply of heat being furnished by hot pipes on the floor,
or by suction from any other source.

COMPLETE SPECIFICATION.
An Improved Drying Machine for Paper or other Materials.
I, JOSEPH ARNOLD, Paper Manufacturer of Eynsford Paper Works, Eynsford,
in the County of Kent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
In my improved drying machine, I have a series of trays, or other suitable.
vehicles, for holding and conveying the material to be dried. These trays are...
suspended between two or more rows of metal or other endless chains or ropes,
passing around and driven by wheels or pulleys at each end, and at the top and
bottom of the machine; and so guided by other wheels and pulleys as to traverse
internally the entire length and height of the machine. The trays, chains or ropes,
wheels, and pulleys, are enclosed in au iron framework which serves to carry them,..
and to afford fixing for the necessary driving apparatus.
The whole of the arrangement is closed in on all sides and above either by suitable
non-conducting material, or by being placed in a close brick or other chamber, two
small openings only being left to permit the passage inwards of the chains or ropes
with the trays laden with damp material, & of the chains or ropes travelling outwards
with the trays laden with dried material.

page_text: Applied towards the top of the chamber containing the machine, I have an
exhaust fan, so arranged as to remove the moisture as it is evolved from the material,
an adequate supply of heat being furnished by hot pipes on the floor, or by suction
from any other source.
The accompanying drawings show the manner in which I propose to construct my
improved drying machine.
Fig. 1. shows an elevation and Fig. 2 a plan of same.
The whole machine is enclosed in a brick or otherwise closed chamber the
drawing Fig. 2. showing brick at A. A. This chamber is honted by, steain, or hot air
pipes shown B. in Figs. 1 and 2. For removing the moisture evolved I have fixed
towards the top of the chamber a suction fan, shown C. in Fig. 2, driven from the
shaft D. There are endless chains E running over chain wheels shown G, these
chains carrying a series of trays F. These trays starting from H. enter the
chamber at the top through a narrow opening I and traverse the chamber slowly from
end to end forward and backward, coming out through another opening J. at the
bottom of the chamber affording an opportunity for removing the dried material
The trays when passing over the back and front chain wheels in tlie chamber are
tilted clear of each other and directed on their return journey by means of curved
guides suitably arranged.
The trays shown in plan in Fig. 3. and in end view Fig. 4. consist of light metal
frames L. Over and throughout these frames are stretched tapes, network cloth, or
any suitable material shown K in Fig. 2. and enlarged at K. in Fig. 3. The trays
are suspended from above on centres M. M. Figs. 3. and 4., on studs N. N which are
riveted or bolted to the chains E. Fig. 1 and E. E. Fig. 2. on each side, and which
run over the chain wheels G. these wheels being driven from the shaft D. by suitable
gearing and a worm wheel or wheels as shown O. in Figs. 1 and 2. Each tray is
furnished with four small wheels P. Figs. 3 and 4. to ensure its easy ruunting, and
guides or rails are fixed on the sides of the machine as shown at Q Figs. 3. and.
In Fig. 1. is shown a method of keeping a tension on the chains E by ineafs of
the chain pulleys R. R. Figs. 1 and 2. which are pivoted in guides and kept in
tension by the weights S. S. passed over the pulleys T. T..
Whatever variation of heat may exist in the chamber each tray traversing the
whole interior space of the chamber, as explained, is subjected to the same conditions,
and this insures regular and even drying of the materials conveyed by the trays.
The heat can be graduated so as to supply what is needed to evolve the moisture, and
the running of the fun C. can be regulated so as to remove the moisture as quickly
as it is evolved.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I. declare that what I
claim is :-
1. The improved drying machine substantially as described and shown in drawings.
2. The improved machine substantially as described and shown. in drawings, for
the purpose of drying materials of all descriptions such as paper, wool, silk, cotton,
and the like, manufactured or unmanufactured.
