AN IMPROVED VENTILATED RAILWAY WAGON
Year: 1884

page_text: I, JOHN KERR of 101 Leadenhall Street, London, Engineer and Contractor hereby
declare the nature of my invention for AN IMPROVED VENTILATED RAILWAY
WAGON to be as follows:-
The object of this invention is to construct an improved ventilated railway
wagon which is particularly adapted for preserving tea from injury during transit
but which may also be used for the carriage of other merchandise.
Such improved construction possesses the essential features of simplicity, economy
and utility and is as follows:
The frame of the wagon is constructed in skeleton with open sides and bottom
while the top is covered in so as to protect the contents from the weather-The
bottom consists of two or more cross bars placed obliquely or otherwise and
rivetted, bolted or otherwise fastened to or placed in the bottom of the frame thus
forming stays which serve to strengthen the same while each side-(and if desired
each end also) is furnished with a corresponding number of vertical standards or
uprights placed opposite to each other-These intermediate standards as also the
four corner uprights or principals of the frame are each fitted with a corresponding
number of suitable angle irons or brackets placed at convenient and corresponding
distances apart from each other so as to form rests or supports for a series of trays
or shelves made of wire netting of any suitable mesh and each fitted with a rim
provided with two lugs or their equivalents placed one at each end which take in
or on to the before mentioned angle irons or brackets and thus keep the trays or
shelves in position.
The tea or other merchandise being placed in or on such trays or shelves the air
circulates freely through the bottom and sides of the van and likewise through the
meshes of the wire netting of the trays or shelves and permeating or filtering
through the entire bulk of the tea or other merchandise therein or thereon thus
effectually obviates injury thereto and especially in the case of tea prevents injury
to the tea leaf in its transit from the fields to the drying factory.
When additional strength is required horizontal bars may be substituted, or
employed in conjunction with the before mentioned intermediate vertical uprights
and the trays or shelves may be made of an iron web in lieu of the wire netting so
as to be capable of carrying considerable weight.
It is obvious that the wagon can be fitted with two or more tiers of trays or
shelves as desired.

page_text: 1, JOHN KERR, of the Office for Patents 33 Southampton Buildings Holborn
Middlesex Engineer and Contractor do hereby declare the nature of my invention
for AN IMPROVED VENTILATED RAILWAY WAGON 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 this invention is to construct an improved ventilated railway
wagon which is particularly adapted for preserving tea from injury during transit,
but which may also be used for the carriage of other merchandise.
Such improved construction possesses the essential features of simplicity economy
and utility and is as follows
:
The accompanying drawings show various views of one of such improved wagons-
Fig 1 shews a view in side elevation-Fig: 2 is a plan view shewing the
arrangement of the cross bars at the bottom of the frame-Fig: 3 shews a view in
end elevation and Fig: 4 is a detail view as presently mentioned.
Similar letters of reference indicate corresponding parts in all the figures.
The frame of the wagon is constructed in skeleton with open sides and bottom
while the top is covered in with a roofing A so as to protect the contents from the
weather-see Figs: 1 and 3-The bottom consists of two or more cross bars (a)
placed obliquely or otherwise, and rivetted bolted or otherwise fastened to or
placed in the bottom of the frame thus forming stays which serve to strengthen
the same; while each side-(and if desired each end also,)-is furnished with a
corresponding number of vertical standards or uprights (b) placed opposite to each
other These intermediate standards as also the four corner uprights or principals (c)
of the frame are each fitted with a corresponding number of suitable angle irons
or brackets (d) placed at convenient and corresponding distances apart from each
other, so as to form rests or supports for a series of trays or shelves (e) made of
wire netting of any suitable mesh, and each provided with a rim (f) furnished
with two projections or lugs (g) or their equivalents placed one at each end, which
take on or in to the before mentioned angle irons or brackets the top flange of each
of such angle irons being turned up at the end so as to keep the trays or shelves in
position-A detail view shewing the flange so turned up is given at Fig: 4.
The tea or other merchandise being placed in or on such trays or shelves the air
circulates freely through the bottom and sides of the van and likewise through the
meshes of the wire netting of the trays or shelves and permeating or filtering
through the entire bulk of the tea, or other merchandise, therein or thereon thus
effectually obviates injury thereto, and especially in the case of tea prevents injury
to the tea leaf in its transit from the fields to the drying factory.
It is obvious that the wagon can be fitted with two or more tiers of trays or
shelves as desired.

page_text: 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
An improved ventilated railway wagon constructed and fitted substantially in the
manner and for the purposes hereinbefore specified and shewn.
