IN THE MODE OF AND MEANS FOR PROMOTING VENTILATION."-A communi-
⚫cation from abroad by Henry Albert Gouge, of Brooklyn, New York,
United States of America.
Sealed the 17th July 1866, and dated the 15th May 1866.
COMPLETE SPECIFICATION filed by the said George Haseltine at
the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 15th May 1866, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 8, Southampton
Buildings, Chancery Lane, in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
THE MODE OF AND MEANS FOR PROMOTING VENTILATION," and have petitioned Her
Majesty to grant unto me, my executors, "administrators, and assigns, Her
Royal Letters Patent for the same, and have made solemn Declaration that

page_text: the same has been communicated to me from abroad by Henry Albert Gouge,
of Brooklyn, New York, United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal, fully
describes and ascertains the nature of the said Invention, and in what
manner the same is to be performed in and by the following statement,
reference being had to the accompanying Drawings making a part of this
Specification, in which the same letter indicates a corresponding part of the
apparatus :-
Figure 1 is a vertical section of my improved apparatus; Figure 2 a
vertical section of the gas burner and draft regulator; Figure 8, a front view
of a portion of the apparatus on an enlarged scale; Figure 4 represents the
apparatus attached to the wall of a room.
A is a pipe or tube extending from the floor or near the floor of the apart-
ment to be ventilated along the interior or exterior surface, or within the
wall of the apartment, if preferred, and communicating at its outlet with
some other room or the open air by a chimney, flue, or otherwise; B, an inner
metal pipe above the gaslight, and extending sufficiently high. to secure
advantageous and safe combustion; C, a chamber containing the burner;
D, the gas burner; E, the inclined plane draft regulator; F, the gas pipe;
G, the metal or glass door of chamber C; H, the lower register; I, the upper
register; and J, the intermediate register.
It is well known that there are two kinds of noxious air in a close apart-
ment; one dense and heavy near the floor, known as carbonic acid gas, the
other light and hot near the ceiling, known as exhausted air. My apparatus
is designed to economically and surely remove both kinds.
By lighting the burner D a current of air is caused to pass through the
open register H and up the pipe A, thereby promoting combustion, while the
intensity of the current will be modified and controlled by the four-sided
inclined plane regulator E, which being largest at the top will so check and
diffuse the ascending current that it will reach the burner in a steady and
even flow, so that regular combustion may not be disturbed. The air in the
chamber C and in the protecting metal pipe B being thus rapidly heated and
rarefied will rise and pass off through the upper part of the pipe A, creating a
current into which, by opening either register I when it is desired to quickly
cool the room, or register J when it is wished to purify the air and save as
much heat as possible, or both if desired, the air in the upper part of the room
containing the noxious gases will be drawn away.
Figures 5 and 6 represent an arrangement more particularly applicable to a

page_text: peculiar class of apartments, such as magazines, refrigerators, bank vaults,
ship state rooms, and the like.
Figure 5 is an elevation thereof, and Figure 6 represents the mode of
applying the same to an apartment. The object of this arrangement of my
Invention is to promote the ventilation of any apartment by creating a current
outside of the same, into which current the impure air of the apartment is
drawn and carried away, the same contrivance also lighting the apartment
without heating it or incurring risk of fire.
K represents a small chamber containing the light outside the apartment to
be ventilated and lighted; L, the ventilating flue; M, the metal radiating
flue from chamber K; N, the protecting cap; O, the ventilator escape;
P, the light; Q, the base of the lighted chamber perforated for the admission
of air to promote combustion; R, the glass door of the chamber; S, the wall
of the apartment to be ventilated and lighted. The light P heats and rarefies
the air in chamber K, which rises in the exterior of the cone N through the
radiating metal flue M, thereby rarefying the air in the ventilating flue L,,
which consequently rises and passes away. The current of heated air in
flue L passing by the open ventilator O draws in the foul and heated air of
the apartinent, and thus secures the desired ventilation. The cone N divides
the current of air and prevents the extinguishing of the light P by the sudden
closing of bank vault or other tight fitting doors which would drive the air im-
petuously through the ventilator O and down the flue M into the chamber K.
It is obvious that this arrangement may be applied in different ways to
many useful and healthful purposes; but it is especially applicable to ven-
tilating and lighting magazines, bank vaults, refrigerators, state rooms of
passenger vessels, and the compartments of railway carriages, with perfect
immunity against accidents by fire.
Figures 7, 8, 9, 10, 11 and 12, represent an arrangement especially
adapted for the ventilation of shops and shop windows. Figure 7 is an
exterior front elevation shewing the interior arrangement; Figure 8, a cross
section of the reflector and gas burner; Figure 9, a vertical section
Figure 10, a plan of the base of the ventilator; Figure 11, a section of the
same; and Figure 12, a plan of the under side thereof.
T represents the bottom and sides of the ventilated apartment; U, the
reflector; V, the ventilating pipe; W, the illuminating gas pipe; X, the
ventilating gas pipe; y, the feed pipe to the illuminating gas burner; Z, the
cold air register; k, the perforated back plate thereof; 1, the slide door
beneath register Z; n, the slide door to close space m beneath the bottom of
the window sill; p, the narrow open space between the inclined plate v and

page_text: the front glass of the window; r, the ventilating door at the top of the
window; t, the inside window door; v, an inclined plate extending from the
bottom of the window sill towards and close to the front window glass'; w, the
ventilating gas burner; i, a slide to close the space h at the top of the
reflector; m, an open space beneath the inclined plate v.
The object of this modification of my Invention is the ventilation of shop
windows, at the same time securing facilities for the ventilation of the shop
itself.
Another important object secured by this arrangement is the prevention
of the condensation of moisture on the inside of the said windows in cold
weather by equalizing the temperature on the inside with that of the outside
of the glass as nearly as possible. This object is attained by creating heat
near the top of the window, which rarefying the air promotes its escape
through the ventilating pipe V, while it causes a current of cold air to ascend
from the bottom of the window sill. In the evening this heat is obtained from
the illuminating gas burner W, in the day by the ventilating gas burner w. The
sliding door over the opening Z in the bottom of the window sill regulates
the amount of air admitted, and the door n controls the admission of air
through the space m directed by the inclined plate against the inside of the
window plate, which it reaches through the passage p, thereby securing cool
air to that surface of the window plate, and preventing condensation of the
moisture thereon. The opening door r and the slide i will assist in the venti-
lation of the shop.

ting in substantially the manner set forth.
