Improvements in Apparatus for Preventing the Steaming of Shop
or other similar Windows.
I, FREDERICK HARRY HEATH, of " Ellerslie," Springfield Road, King's Heath,
near the City of Birmingham, Manager, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in apparatus for preventing the steaming
of shop or other similar windows. It is a common experience that from various
causes, some of which appear almost inexplicable, shop windows become steamed,
and thereby prevent the clear display of goods &c. and otherwise causes incon-
venience.
It is in order to obviate this, that I have made this my invention. Broadly,
I provide a course of pipes, which may be heated by steam, hot air, or water, which
shall be carried around the sash bars, of the window, or otherwise near to the
glass, which said pipes shall also be protected by shields, which said shields shall
also be constructed and arranged, as to throw the heat given off, as much as possible
on to the surface of the glass.
My invention admits of considerable variation in detail, without departure from
it's nature, but generally it consists as follows:-
:-
Sunk underneath the window board, and near to the glass, I provide a channel
or gutter, in which may lie the pipes which are lead thither from the heating.
source. This pipe (or pipes) is carried up and around the various sash bars, or
stiles of the window, or as many of them as may be convenient, and thence back
to the original source or other provided outlet. I further provide a shield or
covering, for such pipes, which said shield shall be so formed, as that it's edge
shall be carried near to the glass, in such a manner, that the heat in it's escape
shall be thrown upon the glass.
The shield may be in one or more pieces, and if desired it's edge parts may be
hinged or otherwise removeable, so that access may be had when desired to the
said pipe or pipes. In the case of the sash bar having glass upon both sides of
it, the pipes would occupy a central position behind such bar, and the shield would
be of a double character, so as to throw the heat upon each side.
Further, the main part of such shields may, when required, be also utilised to
carry the necessary desirable brackets, from which articles for show, or for sale,
may be supported, or upon which shelves or other contrivances may be carried.
These shields may be painted, enamelled, or otherwise ornamented, according to
fancy. The pipes which are carried up, and around the various sash bars, may be
omitted, when the pipes laying in the channel under the window board are found
to be sufficiently potent for the purpose.

or other similar Windows.
I, FREDERICK HARRY HEATH, of "Ellerslie," Springfield Road, King's Heath,
Birmingham, Manager, 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 relates to improvements in apparatus for preventing the steaming
of shop or other similar windows. It is a common experience that from various
causes, some of which appear almost inexplicable, shop windows become steamed,
and thereby prevent the clear display of goods &c., and otherwise causes incon-
venience.
It is in order to obviate this that I have made this my invention, and in order
to more clearly explain my invention, I have appended hereunto an illustrative
drawing having reference numbers. Fig. 1, being a sectional view showing the
application of my invention to a shop window.
Broadly, I provide course of (copper) pipes which may be heated by steam,
hot air, or water, which shall be carried near to the glass; which said pipes shall
also be protected by shields, which said shields shall be so constructed and
arranged as to throw the heat given off, as much as possible on to the surface of
the glass.
My invention admits of considerable variation in detail without departure from
its nature, but generally it consists as follows:-
3, is the window pane. 4, is the window exterior sill. 5, is the interior window
floor level. 6, is the channel or gutter which is sunken below the floor level and in
which lie the heating pipes 7 and 8. Two of such pipes are shown but more or
less may be used. These pipes may be charged with heat by means of hot air,
in which case, such air may be allowed to escape into the channel or gutter 6,
by means of perforations 9, in such pipe; or in the case of the heating agent being
steam or water or the like, the heat given off heats the air in the channel or
gutter 6. The heated air now created in the channel 6, in its upward movement
is now more directly thrown on to the glass 3, by means of the shield 10, which
also serves to conceal the pipes 7 and 8. In order to supply the channel 6, with
air to be heated, I may put one or more feed pipes 11, having a wire gauze or
other filtering medium 12.
The shield may be in one or more pieces, and if desired, its edge parts may be
hinged, or otherwise removable, so that access may be had when desired to the
said pipe or pipes.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The construction of apparatus for the diffusion of heat upon the surface of
windows, wherein the heat is charged into a channel or gutter at the foot of such
window from whence it is thrown on to the glass, substantially as set forth and
shown, and for the purposes specified.
