Ventilating and Air Heating Apparatus.
I, OTTO SCHOLZ, of 60 and 61 Am Strom, Warnemunde Am Ostsee, Empire of
Germany, Hotel Proprietor, 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 its object the introduction of fresh warmed air into rooms
for ventilating purposes. In the case of small rooms the apparatus serves as a
beating apparatus.
The accompanying drawings shew an example of apparatus according to this
invention, Figure 1 being a sectional elevation of a room with the apparatus
applied thereto, and Figure 2 being a sectional plan of the apparatus taken
at X X Figure 1.
According to this invention there is provided a box g, fitted with tubes d, which
is arranged and fitted into the wall of the room, just above the floor, in such a
manner that the outer surface of the tubes & are in communication with the outside
air through a passage f provided with a valve e. The box g is fitted over a funnel
shaped pipe c which serves to conduct the heat from a lamp or other heating means b
through the tubes d, and from thence through a pipe which serves as a withdrawal
pipe to carry off the air which has been heated in the tubes and from the lower
part of the room.
The tubes & being highly heated by the heater b, the fresh cold air coming from
the outside through the passage f becomes heated by surface contact with the hot
tubes d, and passes into the room to be ventilated in a warmed or heated state.
The bad air present in the room is driven away by the incoming fresh air and
passes out of the room through the outlet a, which is placed in a suitable position
for the air exit.
By this invention the incoming fresh air is not only improved by being
warmed or tempered, but in the case of small rooms the apparatus acts as a heating
apparatus.
When it is desired to stop the working of the apparatus, the heat producer 6 can
be put out or removed and the valve or door e of the passage f closed, so as to cut
off the communication with the outer air.
The ventilating apparatus the subject of this invention is suitable for large
or small rooms, more particularly for restaurants and similar rooms which suffer
from bad air.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described improvement connected with the ventilating of rooms
or buildings, consisting in the employment of a heating apparatus having heating
surfaces over which air, introduced into the room or building through a suitable
conduit, is caused to pass in passing into the room or building, and the auto-
matic ventilation of the room or building by fresh and warmed air is effected:
substantially as herein described with reference to and shewn in the drawings
hereto annexed.

shewn in the drawings, operating as and for the purposes specified.
