page_text: respectively above the culverts A, A², and under the floor B. In each culvert C
and C¹, is fixed the hot water or steam pipes D, or any other suitable heating
apparatus, for warming the air prior to it entering the ward.
From the upper part of the culverts or chambers C, C', for warmed air, any
required number of bell mouthed or other outlets E are provided for conveying
such heated air into the hospital ward or dormitory, or other room, or rooms
requiring the same. The outlets E from the hot air chamber D are preferably
arranged in the floor B underneath the beds F, and when required may be raised
a little from the floor as shown and may be covered with gratings so as to be
protected from the dirt.
In the roof G or upper part of the building or enclosure overhead is fixed
or provided one or more extraction flues or culverts H communicating with the
disinfecting furnace J and final exit shaft K. Any desired number of openings I
are provided in the ceilings or lower part of the horizontal portion of the
culvert H for the exit of the vitiated air, said openings being arranged preferably
though not necessarily so, between the parts at which are located the beds as shown
at Figs. 1 and 2.
The ventilating, aspirating, and disinfecting furnace J is provided with the
grate bars K³, above which are two or more firebrick arches L, L', perforated
at as shown. The perforations 1, l' are arranged so that they shall not be
immediately over each other, but in varying positions so that the arches L, L'
may form a kind of baffle plates which on becoming heated act as additional means
for more thoroughly disinfecting the vitiated air prior to it passing into the outer
atmosphere.
The vitiated air after leaving the ward and other rooms of the hospital
passes through outlets I into culvert H, down the vertical portion thereof into
the furnace from the underside of the grate bars K', through contracted
portion H of the culvert H, and also around the side wall of the furnace J. The
vitiated air is thus conveyed to and made to pass through and over a fire in the
furnace J which is at such a high temperature as to perfectly disinfect the air so
that after passing through the arches L, L' it escapes from the chimney in a
perfectly harmless state.
The inlets a, a', for fresh air, outlets for vitiated air I, I, and the culvert or con-
ducting shaft H may be provided with dampers or throttles M. whereby the flow of
air may be regulated according to requirements.
N is the hot water boiler which is made to communicate with the final exit
shaft K by means of the flue n which enters the said shaft K above the
arch L¹.
0, 0, 0, 0, are bath rooms and lavatories provided with hot water radiators P,
and Q, Qdressing or bedrooms, or private wards, all of which may if desired, be
made to communicate with the herein described warming, ventilating, and dis-
infecting arrangement.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The improvements in warming, ventilating and disinfecting hospitals, rooms,
buildings, and the like, consisting of one or more culverts such as A, A', arranged
below the level of the floor, and communicating respectively with the atmosphere
and the hot air culverts or chambers such as C, C, said hot air chambers having
outlets into the interior of the ward or room, an extraction culvert or flue such
as H arranged in the roof for conducting the vitiated atmosphere to an aspirating
and disinfecting furnace such as J, all arranged substantially as described with
reference to Figs. 1 to 8 of the accompanying drawings.
2nd. In the warming, ventilating, and disinfecting of hospitals wards, rooms, and
other buildings, the employment and use of the culverts A, A' communicating
with the outside of a building and with heating chambers C, C', inlets E,

page_text: extraction culvert or flue H, outlets I and furnace J with its allied parts,
substantially as described with reference to Figs. 1 to 8, of the accompanying
drawings.
3rd. The arrangement, construction and application of the various parts forming
the means for warming, ventilating and disinfecting hospital wards rooms, and
other buildings substantially as described and illustrated in the accompanying
drawings.
Dated the Sixteenth day of February 1892.
