I JOHN WESTMORLAND of 27. Seymour Street Liverpool, in the County of
Lancaster, Ventilating Engineer do hereby declare the nature of this invention to
be as follows:-
The object of the invention is to provide improved means for ventilating
buildings, and improving the construction of floors and hearths.
The invention consists First In ventilating buildings by means of a hollow
beam having ventilating openings, and a hollow tail piece, provided with a junction
or junctions leading into a chimney or flue, or chimneys or flues. The said beam is
advantageously located beneath the floor in front of the hearth, with the ventilating
openings leading through the ceiling into the apartment beneath, and with the tail
piece resting on a support at one side of a chimney breast or between two chimney
breasts. "A junction is made from the tail piece into one or both chimneys by means
of a pipe or pipes. Valves may be provided to control the passage of air through
the ventilating appliances, and to allow of access to the interior thereof. More than
one tail piece and junctions may be employed.
Second. In strengthening and rendering more secure the construction of buildings
and hearths by making the hollow ventilating beam in the form of a trimmer with
means of securing it at each end to the flooring joists, and with bearings to receive
the ends of the joists which would be supported by such trimmer.

A further part of the invention consists in so constructing and disposing the
hollow ventilating trimmer that it serves as a carrier for the hearth stone or its
equivalent.

Improvements in the Ventilation and Construction of Buildings.
I JOHN WESTMORLAND of 27 Seymour Street, Liverpool in the County of
Lancaster, Ventilating. Engineer do hereby declare the nature of the said invention
· and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of the invention is to provide means for ventilating buildings and
improving the construction of floors and heartha..
The invention consists-First-In ventilating buildings by means of a hollow
beam, having ventilating openings and a hollow tail piece, provided with a junction
or junctions leading into a chimney or flue, or chimneys, or flues. The said beam is
advantageously located beneath the floor in front of the hearth with the ventilating
openings leading through the ceiling into the apartment beneath and with the tail
piece resting on a support at one side of a chimney breast, or between two chimney
breasts. A junction is made from the tail piece into one or both chimneys, by
means of a pipe or pipes. Valves may be provided to control the passage of air
through the ventilating appliances and to allow access to the interior thereof.
More than one tailpiece and junctions may be employed.
Second-In strengthening and rendering more secure the construction of
buildings and hearths by making the hollow ventilating beam in the form of a
trimmer with means of securing it at each end to the flooring joists and with
bearings to receive the ends of the joists which would be supported by such :
trimmer.
A further part of the invention consists in so constructing and disposing the
hollow ventilating trimmer that it serves as a carrier for the hearth stone or its
equivalent.
Figs. 1, and 2. are vertical sections at right angles to each other, and Fig. 3. a
horizontal section of so much of a building as is necessary to illustrate my
invention.
Under the first part a. is a hollow beam, having ventilating openings b. and a
hollow tail piece c. provided with junctions d. leading to flues e.--The beam a. is
located beneath the floor in front of the hearth and is under the second part made
in the form of a trimmer and secured at each end to flooring joists f. so as to form
a support for the joists f¹-which are usually supported by the trimmer.-Under
the third part the hollow beam a and its connections are so made and disposed
as to support the, hearth stone g.-The arrow shews the direction of the air
currents.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
First Ventilating buildings by the means and in the manner set forth.
Second Ventilating appliances consisting of a hollow beam and tail piece
constructed and connected substantially as set forth.
Third Constructing buildings with ventilating appliances, constructed and
disposed to serve as joist carriers and hearth support, substantially as set forth.
