PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of the Reservoirs of Automatic
Air Brakes and in Attaching the said Reservoirs to the Bottoms
of Railway Carriages and Wagons.
I HENRY HOWARD of the firm of Lloyd and Lloyd of Coombs' Wood Halesowen
in the County of Worcester Manufacturers do hereby declare the nature of this
Invention to be as follows:-
My invention consists in manufacturing in the ways hereinafter described the said
reservoirs and in the method of attaching the same to the bottoms of railway carriages
and wagons.
In making one of the said reservoirs according to my invention I take a hollow
cylinder or tube of wrought iron or steel of the diameter of the reservoir to bo
made and of a length somewhat greater than that of the finished reservoir. I
form one of the closed ends of the reservoir of a circular plate or disc of wrought
iron or steel the edge of which is turned at right angles to the other part of the
disc so as to give the said disc a cupped form. The said cupped disc is preferably
made of stronger sheet iron or steel than the cylindrical body of reservoir. The
said cupped disc fits the end of the body tightly and after having been introduced
into the end of the body its concave side outwards it is secured in position by welding
or brazing.
I form the other end of the reservoir of a similar disc of sheet iron or steel and
weld it in its place. Or instead of making the said end of a circular disc I make
it of the figure of a circular disc with a rectangular piece on
one side which
rectangular piece may be bent into the figure of the bracket required for attaching
the reservoir to the carriage or wagon. Or instead of making the bracket in one
piece with one of the ends of the reservoir the said bracket may be made of a
separate piece of sheet wrought iron or steel and attached to the reservoir by welding
brazing or screwing.

Improvements in the Manufacture of the Reservoirs of Automatic
Air Brakes and in Attaching the said Reservoirs to the Bottoms
of Railway Carriages and Wagons.
I HENRY HOWARD of the firm of Lloyd and Lloyd of Coomb's Wood Halesowen
in the County of Worcester Manufacturers do hereby declare the nature of my
Invention and the manner in which the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention consists in manufacturing in the ways hereinafter described the said
reservoirs and in the method of attaching the same to the bottoms of railway carriages
and wagons.
In making one of the said reservoirs according to my invention I take a hollow
cylinder or tube of wrought iron or steel of the diameter of the reservoir to be
made and of a length somewhat greater than that of the finished reservoir. I form
one of the closed ends of the reservoir of a circular plate or disc of wrought iron
or steel the edge of which is turned at right angles to the other part of the disc so
as to give the said disc a cupped form. The said cupped disc is preferably made
of stronger sheet iron or steel than the cylindrical body of the reservoir. The said

page_text: cupped disc fits the end of the body tightly and after having been introduced into
the end of the body its concave side outwards it is secured in position by welding
or brazing.
I form the other end of the reservoir of a similar disc of sheet iron or steel and
weld it in its place. Or instead of making the first mentioned end of a circular
disc I make it of the figure of a circular disc with a rectangular piece on one side
which rectangular piece may be bent into the figure of the bracket required for
attaching the reservoir to the carriage or wagon. Or instead of making the bracket
in one piece with one of the ends of the reservoir the said bracket may be made of
a separate piece of sheet wrought iron or steel and attached to the reservoir by
welding brazing or screwing.
Figure 1 of the accompanying Drawing represents in longitudinal section the
reservoir of an automatic air brake made according to my invention and Figures 2
and 3 represent elevations of opposite ends of the said reservoir Figures 1 and 2
also exhibit my method of attaching the said reservoirs to the bottoms of railway
carriages and wagons.
The same letters of reference indicate the same parts in the several Figures of the
Drawing.
a is the body of the reservoir made of a hollow cylinder or tube of wrought iron
or steel 66² is the cupped disc by which one end of the body a is closed the edge.
of the disc turned at right angles to the disc being marked 62. The said cupped disc
is made convex at its middle. It will be seen that the said cupped disc is made of
stronger sheet iron or steel than the cylindrical body a of the reservoir. The said
cupped disc b² is made of such a diameter that it fits in the end of the body a
tightly and after the disc has been introduced into the end of the body in the
position represented it is secured in its place by welding the cupped edge b² of the
said disc to the interior of the cylindrical body a as represented in the drawing. Or
the cupped edge of the disc may be connected to the end of the cylindrical body by
brazing. I form the other end of the cylindrical body a of a flat disce or a flat disc
with a cupped edge of stronger iron or steel than the said body and I weld or braze
the said end by its edge or by its cupped edge to the interior of the cylindrical
body a.
In the middle of the cupped disc 662 is a hole 63 and near the said hole are
screws upon which screw nuts are fitted for connecting the reservoir with the
air pipe of the brake and the end e of the reservoir is furnished with screws and
screw nuts at f for attaching the reservoir to the brake cylinder.
A brass tube c for the usual purpose passing through the reservoir is fixed in the
ends be as represented.
For the purpose of attaching the reservoir to the bottom of the railway carriage
or wagon 1 use the horizontal bracket g made in one piece with or attached to the
end 6 of the reservoir the said bracket g being punched with holes through which the
fixing screw bolts are passed.
When the bracket is made in one piece with the end b of the reservoir the circular
disc from which the cupped end b is made has a rectangular piece on one side of it
which is bent or fashioned into the horizontal bracket g. When the bracket g is
made separate from the cupped end 6 it is attached to the said end 6 of the reservoir
by welding brazing or screwing.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in the manufacture of the reservoirs of automatic
air brakes and in attaching the said reservoirs to the bottoms of railway carriages
and wagons
"
:-
First Making the reservoirs of automatic air brakes by welding or brazing into
one end of a hollow or tubular body of iron or steel a cupped disc of iron or steel
and into the other end either a flat or cupped disc of iron or steel substantially as
herein before described and illustrated in the accompanying Drawing.

page_text: Secondly Attaching the reservoirs of automatic air brakes to the bottoms of rail-
way carriages and wagons by means of a horizontal bracket formed in one piece
with one of the ends of the reservoir or formed separately from the reservoir and
attached to the end of the reservoir by welding brazing or screwing substantially as
hereinbefore described and illustrated in the accompanying Drawing.
