BOARD DRYING APPARATUS, APPLICABLE TO SIMILAR DRYING PURPOSES."
PROVISIONAL SPECIFICATION left by the said Robert Russell at the
Office of the Commissioners of Patents, with his Petition, on the
15th June 1871.
I, ROBERT RUSSELL, of 3, Wellington Place, Belfast, in Ireland, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PAPER AND CARDBOARD DRYING APPARATUS, APPLICABLE TO SIMILAR DRYING
PURPOSES," to be as follows:-
This Invention relates to the construction of wire racks for drying
purposes, such as for drying paper, cardboards, surface coloring, and
japan papers. The advantages are the saving of space, time, and labour,
especially in keeping the edges of the papers or articles clean and free
from dust.
The rack arrangement referred to is as follows, namely:-There is a
frame supported on four flanged wheels or rollers. To this a front plate

page_text: The frame and
or door (provided with suitable handle) is attached to close up opening
of the closet or oven hereafter described. Attached to the frame is a
wire rack, the spaces between the wires of which are constructed to
stand upright and removable, say about one-eight of an inch apart and
upwards accordingly as the material is thin or thick. For the wheels
or rollers of the frame to travel on rails are provided.
rack are used in closets or ovens made wide enough to allow the flange
wheels or rollers to clear themselves; these closets or ovens are heated
by hot air or steam pipes in the ordinary way. A channel is provided
by which cold air enters, fills a chamber connected with the ovens or
closets, there being a damper to regulate the current of hot air which
rises by a series of holes into another chamber containing hot air or
steam pipes. The floor of the closet or oven is covered all over except
at one part, which is covered by an open grating of cast iron the full
width of the closets or ovens; through this the heated air rises in a
body to the ceiling or roof, where it is distributed and descends at the
back to an opening, by which it escapes into the chimney or shaft, and
thence into the atmosphere.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Russell in the Great Seal Patent Office on
the 14th December 1871.

thick. For the wheels or rollers of the frame to travel on rails D are
provided, which are prolonged outside to accomidate the frame or
frames A, E is a handle attached to the plate or door B with which
to draw out the frame A. The frame and rack are used in closets or
ovens F made wide enough to allow the flange wheels or rollers to clear
themselves; these closets or ovens are heated by hot air or steam pipes
in the ordinary way. G is a channel by which cold air enters and fills a
chamber H, connected with the ovens or closets; there is a damper S
to regulate the current of hot air which rises by a series of holes into
another chamber J containing hot air or steam pipes R. The floor of
the closet or oven F is covered all over except from L to M, which is
covered by an open grating of cast iron the full width of the closets
or ovens; through this the heated air rises in a body to the ceiling or
roof, where it is distributed and descends at the back to an opening N
by which it escapes into the chimney or shaft O and thence into the
atmosphere.
Having now particularly described and ascertained the nature and
object of my said Invention, and in what manner the same may be
performed or carried out in practice, I hereby declare that I claim, the
Invention of "Improvements in Paper and Cardboard Drying Apparatus
applicable to similar Drying Purposes," as herein-before described and
illustrated by the Drawings, it being understood that I do not claim
the individual mechanical details per se except as forming constituent
parts of my herein-before described Invention.
In witness whereof, I, the said Robert Russell, have hereunto set
