PROVISIONAL SPECIFICATION left by the said Raphael Hunter Brandon
at the Office of the Commissioners of Patents on the 17th March 1883.
RAPHAEL HUNTER BRANDON of N° 1 rue Laffitte Paris in the Republic of
France Engineer and Patent Agent "IMPROVEMENTS IN THE CONSTRUCTION AND
ARRANGEMENT OF VENTILATING APPARATUS FOR RAILWAY CARS AND OTHER
VEHICLES," A communication to me from Prince Joseph Piguatelli d'Aragon
residing at present at N° 1 rue Laffitte Paris, France,
These improvements have reference to the construction and arrangement of
ventilating apparatus for Railway cars and other vehicles and are mainly
improvements on the mechanism patented by me 1st September 1882 N° 4179
Improvements in ventilators for Railway carriages, Tramway cars and other
vehicles,"
**
Some of the most important of these improvements are enumerated below and
illustrated in the 6 figures of the accompanying drawing.
First improvement. Fig 1
This improvement has reference to the mouth piece 1 and consists in adapting
in its delivery end a truncated cone 2.
Second improvement fig 1 and 2,
This improvement has reference to the air and water box 3 and consists in
placing one upright division 4 in the same centrally under the cone 2 of the mouth
piece and a removable water rack 5 on the off side of the said box.
Third improvement Fig 3 and 4

page_text: This improvement has reference to the air pipe 6 through which the air passes
from the box 3 into the Railway car or other vehicle, it consists in making the
first leg of this pipe through which the air rises from the box 3 shorter than the
second leg of the same through which the air descends into the vehicle, these two
legs being united by a swelling 7.
Fourth improvement Fig 3 and 5
This improvement bas reference to the discharge of superfluous water from the
apparatus and consists in the application to the swelling 7 of a small open pipe 8
situated just below the level of the upper edge of the box 3.
Fifth improvement Fig 5
This improvement has reference to the distribution of the air in the vehicles
and consists in starting from the air box 3 two or more air pipes 6 each being
directed in a separate compartment of a Railway car or other vehicle divided in
compartments or in different parts of a vehicle not divided into compartments.

by the said Raphael Hunter Brandon in the Great Seal Patent Office on the
12th September 1883.
RAPHAEL HUNTER BRANDON of N° 1 rue Laffitte, Paris in the Republic of
France, engineer and patent agent, "IMPROVEMENTS IN THE CONSTRUCTION AND
ARRANGEMENT OF VENTILATING APPARATUS FOR RAILWAY CARS AND OTHER
"
VEHICLES (a communication to me by Prince Joseph Pignatelli d'Aragon residing
at present at N° 1 rue Laffitte, Paris, France)
These improvements have reference to the construction and arrangement of
ventilating apparatus for railway cars and other vehicles and are mainly
improvements on the mechanism patented by me September 1st 1882 N° 4179.
Improvements in ventilators for railway carriages, tramway cars and other
vehicles".
"
These improvements are described in the following specification, conjointly with
the eight figures of the accompanying drawing. First improvement fig: 1 Fig: 1
is a longitudinal elevation in section through A, B fig: 3. This improvement has
reference to the mouth piece a and consists in adapting in its delivery end a
truncated cone b for the purpose of narrowing the orifice through which air is let
into the apparatus. This arrangement has the advantage that the air, which is
drawn in, is projected with more force onto the surface of the water, so that the
dust or impurities drawn along by the air is unavoidably seized by the water.
Instead of adapting a cone b, as above stated, the small end of the funnel a may be
made narrower or taper to fulfil the same purpose, and I wish it to be understood
also that the curved part or bend, of the funnel may be tapered, if requisite.
Second improvement fig: 2 & 3. Fig: 2 is a longitudinal elevation in section
through CD fig: 3.-Fig: 3 is a plan.-This improvement has reference to the
pipe c starting from above the water-box d and leading the air entering the
apparatus, into the inside of the vehicle. It consists in making such pipe c shorter
than the part e of the same pipe, which conducts the air to the interior of the
vehicle. Both parts c, e are connected at a swelling f, acting as a pocket. This
arrangement offers additional security against the passage of any water drawn in
with the air into the vehicle, for the air, in rising in the pipe c, is thrown against
the wall g where any water which may still be contained in the air, adheres to the
said wall & runs down into the pocket f of the swelling, from which it is returned
into the box d through the pipe h, as is the case with the arrangement of apparatus
shown in the aforementioned patent.
Third improvement fig: 2. Into the swelling or pocket f, at about half way
of its height, is screwed or otherwise secured an open pipe i fig: 2 acting as an
overflow for any excess of water which may collect abruptly in the pocket f
and be prevented, from any cause, from returning quickly into the box d by the
pipe h.
Fourth improvement, fig: 4, 5, 6 & 7. Fig: 4 is a plan; fig: 5 an elevation in
section through the line E F fig: 4; fig: 6 modification, fig: 7 plan of the water
box d. This improvement has reference to the distribution of air into the vehicles
to be ventilated and consists in adapting two or more air pipes j, k starting from
above the water-box d and each leading into separate compartments of a railway
or other carriage which is divided into compartments or at different places of an
undivided carriage. The construction of the parts, as well as the arrangement
thereof remain the same, except that the water-box d is provided with a double
water divider made of two separate parts l, m, in order that the said divider may
.

page_text: be easily taken out of the box d through the narrow door n, fig: 4.-Fig: 6 is a
modification of the above arrangement described with reference to fig: 4 & 5.
According to this modification, one single pipe starts from the water box d and
leads into branch pipes j¹¹. A partition o shown in dotted lines is placed at the
bottom of the air inlet pipe. I wish it to be understood that when the ventilating
apparatus is not to be in use, as for instance in cold seasons, it may remain
permanently secured to the carriage, and the opening of the funnel a can be
stopped by any suitable plug. I however prefer removing the said funnel and
closing the opening left by the same by a plug such as. p, fig:8.-Fifth improve-
ment fig: 1 & 3. This improvement has reference to the device used as a level
indicator for the water introduced into the box d; it consists in suppressing the
cock (shown by the letter g in the aforesaid patent) and replacing it by a simple
disk g of soft rubber or other suitable material which acts as a stopper for closing
the hole in the side of the water box d. The disk q is secured to an angle iron r
rivetted or otherwise fixed to the lid s of the said-box; the lid s is pivoted to the
water box, the dotted lines fig: 1 showing its position when the box is being filled.
When the water charged in the box has attained the proper level, it flows out of
the hole made at the side and the attendant then lowers the lid 's together with
the stopper q and the hole is automatically closed. By this arrangement, I save the
cost of a cock, avoid its manipulation and at the same time prevent the clogging
up of the hole as when occupied by a cock.-I Claim: First. The arrangement of
the air feed pipe composed of two parts c, e, the one c of which is shorter than the
other e, as described and shown and for the purpose set forth.-Second. The
adaptation, to the swelling or pocket f, of a small open pipe i, as described and
shown, and for the purpose set forth.-Third. The adaptation, to the water-box d,
of two or more branch pipes j, as described & shown and for the purposes set
forth. Fourth. The arrangement of a stopper q secured to the angle iron r. and
operated by the action of the lid s, as described and shown, and for the purpose
set forth. Fifth. The general construction and arrangement of ventilating apparatus,
as herein described & shown.
In Witness whereof, I the said Raphael Hunter Brandon have hereunto set my
hand and seal this 8th day of September in the year of our Lord 1883
