PROVISIONAL SPECIFICATION.
An Apparatus for Ventilating and Cooling.
I, FRANCIS FAYOD, Engineer, of 39 Rami Strasse, Zurich, in Switzerland, do
hereby declare the nature of this invention to be as follows:-
This invention refers to improvements in apparatus for ventilating and cooling
of rooms, by means of the well known water spray instrument or syringes, the same
of an improved construction.
The ventilating apparatus has three arms connected together like the prongs of a
fork of which the two outer ones contain each one of the above mentioned syringes.
In the lower part of these arms are turnable regulating valves. The middle arm is
of a larger diameter than the outer ones in order to have room for the ice baskets
which are placed in the arm. In the upper part of the middle arm leads a pipe
which goes into the open air, above this is a regulating valve and then an opening
leading into the room which is to be ventilated or cooled.
By means of a water pipe, provided with the necessary cocks and branches
forcing-water is conducted to the two syringes.
For instance now, if the syringe in one arm is at work and the valve in this arm open,
but closed in the other outer arm, the down running water from the syringe sucks
in the air, which is in the room where the apparatus stands, into the first mentioned
arm, the air rises in the middle arm, is cooled by ice baskets placed therein and
enters again at the top opening into the room as cold air.
To expell foul air from a room the valve in the middle arm is closed and a valve
in the pipe that leads to the open air is opened, by this means the air is sucked in.
by the syringe, enters the outer arm, ascends in the middle arm and escapes by a
pipe into the open air; it is understood that during this process no ice baskets are
placed in the middle arm.
When the syringe in the one arm is at work, the syringe in the other arm may
also be set to work, by arranging the valves accordingly. The apparatus therefore
has a double power.
In case the air is not cooled enough by the ice baskets in the middle arm and it.
is desired to cool the air to a higher degree with the ventilation apparatus a
separate refrigerative apparatus is used at the same time.
The latter consist in the main of a flat but wide channel of galvanized iron
having undulations and which is placed in an isolated wooden box.
The intervals of the undulations of the channel are filled with ice, or ice baskets,
or ice cases may be placed.
If now the top opening of the middle arm of the ventilating apparatus is connected
by a pipe with the channel of the refrigerating apparatus, so must the air forced
by the ventilating apparatus through the undulations of the channel in the
refrigerative apparatus, be cooled to a high degree, before it leaves the refrigera-
tive apparatus and reaches its destination.

I, FRANCIS FAYOD, of 39 Rami Strasse, Zurich in Switzerland, Engineer, 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 reference to improvements in apparatus for the ventilating
and cooling of rooms or for the production of cold air by means of the well known.
water-syringes, for which, on an improved principle of construction I have taken
out a patent ciz. No. 11931 of 1890.
In the accompanying drawing the invention in question has been illustrated in
connection with a double-acting ventilating apparatus the latter having three.
arms C, D, and E, (Figs. 1, and 2,) made of sheet iron. In the arms C and D two
syringes A and B are affixed. The lower portion of C and D contains the rotating
regulating valves and ². A pipe E¹ with the aperture E2 opens out from the
central arm E; and El contains the regulating valve r. At E by means of the
aperture F the pipe F is affixed, containing the regulating valve 3 (Fig. 2).
The pipe F opens outside, whereas the apparatus itself is placed in the room which
is to be ventilated.
Baskets filled with ice are placed in the arm E and the design of such an ice
basket H is given herewith, wherein the arrangement may be seen in Figs. 1, and 4.
It is made of vertical bars which are soldered below to the bottom and at the
top to a ring 2. The thread of a screw made of tin is placed round the bars.
By means of a similar arrangement of vertical bars 3 an open space is created in
the centre of the basket, wherein glass bottles or other vessels are placed, f
arranged on the top of each other in a stand" (Fig. 3), and filled with a
refrigerating mixture. This may consist of sulphate of soda and sulphuric acid,
muriatic acid or nitric acid or also of ice and muriatic acid or sulphuric acid.
By means of a main pipe t water is conducted from a water main under pressure
or from a forcing pump. This water under pressure is distributed by means of
cocks 3 and 4 into pipes t' and 2, leading into the syringes A and B. For example,
if the cock is opened, water flows from the syringe B into the arm D, the jet of
water which escapes, attracting air in a well known manner and this air enters from
the room at D', passes valve 2 and ascends to E, ¹ being closed. The air ascends
in a spiral direction along the ice basket H, where it is cooled, passes through
valve into the pipe E¹ and re-enters the room through aperture after it has
been cooled. In the event of arm E containing no ice or any other refrigerating
substance, the air will only be moistened through contact with the water of the
syringe. For the purpose of expelling foul air from the room, valve is opened
and is closed, whereupon the air is attracted at D', passing the arm E, which is
not filled with ice baskets and escaping into the open air at F1 and F. If further,
valve is opened and syringe A is put into activity by means of opening the
cock t, the apparatus has a double effect, as both the arms C and D attract air and
expel same either to E or F as above described. The water which has escaped
from syringes A and B flows through a perforated basket w and is carried away
through pipe w
Should it be desirable to cool the air to a greater extent, the cooling case G is
used. It consists of a wooden case, coated inside with an isolating coating. A flat
conduit is placed in the case in a serpentine shape in such a manner, that
interstices are formed, where pieces of ice or baskets containing ice are placed.
The conduit can be connected by means of a pipe with the aperture E³ of the
ventilating apparatus, the pipe leading into the room which is to be cooled.
When the ventilating apparatus is put into motion, the air which has been attracted
by one or both of the arms C and D, escapes from E' through E² to l' and passes

page_text: from there through the conduit l. In its long transit through the conduit the air
is cooled considerably and finally escapes through or is conducted still further.
By means of the ventilating apparatus with the ice basket placed therein and
aided by the refrigerating case G, with the use of refrigerating mixtures, large
quantities of air may be cooled even to below freezing point.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The ventilating apparatus consisting of three arms with two syringes in the
outer arms and ice cases in the middle arm, substantially as herein described and
according to Figs. 1 and 2.
2. The arrangement of an ice refrigerator H in the middle arm of the ventilating
apparatus in such a manner that the basket made of vertical bars is supplied with
the thread of a screw leaning against the wall of E, so as to force the air,
passing through E, to form a long circuitous path, substantially as herein described.
3. The combination of a ventilating apparatus with an air cooling apparatus G,
the latter consisting of a conduit placed in a case in a serpentine direction in such
a manner as to form interstices for the reception of pieces of ice or cases containing
ice for the purpose of cooling the air which is forced through the conduit, substan-
tially as herein described.
