PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Air by Steam or
Vapour Heat.
We, GEORGE SEAGRAVE, of Cooks Folly, Walthamstow, County of Essex,
Engineer, and SAMUEL BOURNE BEVINGTON, of Neckinger Mills, Bermondsey
in the County of London, Colonel of Volunteers and Leather Manufacturer do
hereby declare the nature of this invention to be as follows:-
This invention has for object an apparatus for heating air for drying purposes.
To carry our invention into practice, we construct or cast a lower box in two
parts with necessary flanges or bearers, one end of said box has a flanged inlet at
either side to form steam or vapour entries from the right or from the left hand
feed, or for the attachment of other or similarly formed boxes for extension
purposes. This box has one or more partitions for effecting a sinuous travel of
the steam or vapour to and from a series of pipes which connect said box with an
upper box similarly made with the exception of not having the steam or vapour
inlets. These pipes are fitted to the upper and lower of the half boxes respectively
and are of large diameter compared to other pipes arranged within them and
having their ends connected to the bottom and top halves of the boxes respectively,
whereby annular spaces are formed between the two boxes for the free flow of heat
the other or inner pipes being so arranged that air can be drawn down them
by a fan, air also passes end ways or sideways in a zigzag manner around the outer
tubes to the fan.
One end of the casing may be entirely open, or it may be partially or wholly
closed and openings made in the side opposite the fan in order that a full volume
of air can be drawn in by the fan and thus expelled from the heater.
We provide an outlet for the condensed water.

Improvements in Apparatus for Heating Air by Steam or
Vapour Heat.
We, GEORGE SEAGRAVE, of Cooks Folly, Walthamstow, County of Essex,
Engineer, and SAMUEL BOURNE BEVINGTON of Neckinger Mills, Bermondsey
in the County of London, Colonel of Volunteers and Leather Manufacturer, 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 an apparatus for heating air for drying purposes.
To carry our invention into practice and as we show in the annexed drawings,
Figure 1 section through a, a. Figure 2 section through b, b. Figure 3 section

page_text: through c, c, we construct or cast a lower or end box in two parts A, B, with
necessary flanges or bearers for bolting them together, one end of said box A has
a flanged inlet C at either side to form steam or vapour entries from the right or
from the left hand, or for the attachment of other or similarly formed boxes for
extension purposes. This box has one or more partitions D for effecting a sinuous
travel of the steam or vapour to and from a series of pipes E, E, which connect
said box with an upper box F similarly made in two parts F, G, with the exception
of not having the steam or vapour inlets. These pipes E, E, are fitted to the
upper portion A of the lower box and to the lower portion F of the upper box
respectively and are of large diameter compared to other pipes H, H, arranged
within them and having their ends connected to the bottom B of the lower box
and to the top portion G of the upper box respectively whereby annular spaces I, I,
are formed between the two sets of pipes E, H, for the free flow of steam or
vapour heat, the other or inner pipes H being so arranged that air can be drawn
or forced down or along within them by a fan, air also passes end ways or sideways
in contact with and around the outer pipes E in a zigzag manner to or from
the fan.
One end of the casing, if a casing be used, may be entirely open, or it may be
partially or wholly closed and openings made in the side opposite the fan in order
that a full volume of air can be drawn in by the fan and thus expelled from the
heater.
We provide an outlet J for the condensed water.
The invention herein described is specially adapted for heating air from the
exhaust of an engine for warming buildings, for drying clothes in a laundry, or
distribution among material used in trade say leather factories, for use under
evaporating pans or trays in chemical works, dye works, sugar refineries, and in
places generally.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The novel construction of apparatus as above described and as represented in
the annexed drawings.
2. The construction of flanged half boxes having holes of diameters, in their
respective halves for the reception of, and connection by, pipes of corresponding
diameters, whereby the two boxes are in communication by annular channels
between such pipes for passage of steam or vapour heat and for air passage
through the inner pipes and around and between the outer pipes as described
and substantially as represented in the annexed drawings.
