Improvements in Apparatus or Means for Effecting the Drying of
Goods or Material.
We GEORGE SEAGRAVE of Cooks Folly, Walthamstow, County of Essex, Engineer
and SAMUEL BOURNE BEVINGTON, of Neckinger Mills, Bermondsey, County of
Surrey, Leather Manufacturer and Colonel of Volunteers, do hereby declare the
nature of our said invention to be as follows:-
This invention has for object improvements in apparatus or means for effecting
the drying of goods or material.
For the purpose of our invention, we erect a tall "well" in a building or into
as many floors as found necessary, and fit sliding or other doors to the openings
thereof.
We provide tram or trolly metals or rails on or in the ordinary flooring with
the necessary turntables for diverting the trollys from one line of metals to
another to give facilities for loading and emptying the trollys which are run
on same.
Instead of the "well" being used for the trollys, it can, say a narrower one,
be used for the pipes by which hot dry air from a generator or other apparatus
for imparting heat to air drawn or forced into and among the goods or material
in or on the trollys, which for drying purposes are run in and enclosed in the
compartments and for the time isolated from other parts of the building.
If the smaller "well" be provided, we prefer to fit the upper part of each
drying compartment with a branch cone leading from a main hot dry air supply,
said cone or it may be a flat screen like branch having slots at intervals as outlets,
and the cones or other branches may have deflector plates for directing the hot
currents into the required directions for diffusion among the goods or material in
or on the trollys.
For some goods or material the trollys would be provided with perforated or
meshed flooring or staging, and for others with rails or upright screens such as
for hanging clothes on, in such cases it is preferable that the hot air be forced
in at the top or above the goods and be sucked out by a fan from the lower part,
in most cases however a suction fan will only be necessary which would extract
the air from the drying chambers and create a flow through the heating apparatus.
Various methods of heating air in large volume can be adopted to carry out our
system of drying, but we prefer that of heating by exhaust steam or by vapour heat
already patented by us on the 8th day of February 1895 No. 2826, and on the
26th day of March 1895 No. 6272.
If the larger "well" be used, we may separate each chamber by half meshed flooring
to compel the heated air to pass to opposite sides of the chambers respectively.
The air heating apparatus may be in the basement or other part of the building or
in proximity thereto as found convenient.
From the foregoing it will be seen that the drying chambers are above or higher
than one another, but all or any number of them can be on the same level, the air
supply being arranged accordingly.

Improvements in Apparatus or Means for Effecting the Drying of
Goods or Material.
We, GEORGE SEAGRAVE, of Cooks Folly, Walthamstow, County of Essex, Engineer,
and SAMUEL BOURNE BEVINGTON, of Neckinger Mills, Bermondsey, County of
Surrey, Leather Manufacturer and Colonel of Volunteers, 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 :-
This invention has for object improvements in apparatus or means for effecting the
drying of goods or material.
For the purpose of our invention, we erect a tall "well" A in a building B into as
many floors as found necessary in the manner shown in Figure 1 of the annexed
drawings, which represents a part sectional elevation of such a "well" divided
into floors which are perforated.
Figure 2 is a part sectional elevation of a "well" divided into floors and fitted
with branch distributing pipes at the upper part of each division;
Figure 3 being a sectional plan showing the system of tram or trolly lines which
may be arranged on each floor, and
Figure 4 is a sectional elevation of a chamber in which distributing pipes are fitted
above and below the ceiling and below the floor.
Each compartment is fitted with sliding or other doors C. We provide tram or
trolly metals or rails D on or in the ordinary flooring with the necessary turn
tables E for diverting the trollys E' from one line of metals to another to give
facilities for loading and emptying the trollys which are run on same.
Instead of the "well" being open and each compartment communicating with the
other by a meshed floor, as in Figure 1, it can be divided off and fitted with main
pipes G by which hot dry air from a generator or generators H, H, (or other
apparatus for imparting heat to air) is drawn or forced into and among the goods or
material in or on the trollys which for drying purposes are run in and enclosed in
the compartments and for the time isolated from other parts of the building.
If this smaller "well" or isolated divided compartments he provided, we prefer
to fit the upper part of each drying compartment with a branch cone I leading from a
main hot dry air supply G as shown in Figures 2 and 3, said cone (or it may be
a flat screen like branch) having slots J at intervals as outlets, and the cones or other
branches may have deflector plates K on one side of the slots for assisting and
directing the lot currents into the required directions for diffusion among the goods
or material in or on the trollys.
For some goods or material the trollys El would be provided with perforated or
meshed flooring or staging, and for others with rails or upright removable screens L,
such as for hanging clothes on, in such cases it is preferable that the hot air be forced
in at the top or above the goods as indicated in Figures 2 and 3, or the moistened air
be sucked out by a fan from the lower part through the passage M which although
shown applied to the lower compartment only may if desirable be fitted to each
floor, in most cases however a suction fan N will only be necessary which would
by suction extract the air from the drying chambers and create a flow through
the heating apparatus from the bottom to the top as shown in Figure 1, in which
the fan N is shown in the top floor and the heater H under the ground floor, each
intervening floor 1-2 within the "well"A being perforated or fitted with meshed
flooring to allow of the free flow of hot air through the "well" induced by the
action of the fan. We have shown the fan in the top floor as an example but
we may place it in a position to induce a horizontal flow of air through compart-
ments arranged side by side if desired.
Various methods of heating air in large volume can be adopted to carry out

page_text: our system of drying but we prefer that of heating by exhaust steam or by vapour
heat already patented by us on the 8th day of February 1895 No. 2826, and on the
26th day of March 1895, No. 6272.
If the larger "well" A, as shown in Figure 1, be used we may separate each
chamber by half meshed flooring instead of providing same with openings the
whole breadth of the floor and by this means compel the heated air to pass to
opposite sides of the chambers respectively if this should be desirable.
The air heating apparatus H may be in the basement, as shown, or in any other
part of the building, or in proximity thereto as found. convenient.
From the foregoing it will be seen that the drying chambers are above or higher
than one another, but ali or any number of them can be on the same level, the air
supply being arranged accordingly.
Means may also be provided for cutting off any of the chambers, such as by
dampers in the branch cones.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements in apparatus for effecting the drying of goods or materials
by induced or forced hot air currents, or by combined means for forcing hot dry air
currents amongst the goods to be dried and withdrawing the moist vapour as
herein before described with reference to the examples shown in the annexed
drawings.
2. As improvements in apparatus and means for effecting the drying of goods or
material, the arrangement within or as part of a building of a "well" divided into
compartments by perforated or meshed floors for the reception of trollys upon which
the goods to be dried can be placed or suspended and run into the compartment and
be shut off from the main building by sliding or other doors, and providing said
"well" with a fan and air heater for inducing a current of hot air throughout the
"well" and amongst the goods in the several compartments, as described and
arranged in the manner substantially as shown in Figure 1 of the annexed
drawings.
3. The improvements in apparatus or means for effecting the drying of goods or
material, consisting in the arrangement of a slotted branch cone in the upper part of
isolated compartments, as in Figure 2, or in the upper and lower part of similar
compartments, as shown in Figure 4, through which hot air is drawn or forced for
diffusion amongst the goods or material to be dried by means of a main pipe common
to several branch cones, all as described and arranged substantially as shown with
reference to Figures 2, 3 and 4 of the annexed drawings.
