Year: 1884

page_text: I, BASIL FIELD of N° 36 Lincolns Inn Fields in the County of Middlesex
Solicitor do hereby declare the nature of my said invention for "IMPROVEMENTS
IN BAIT CANS AND THE MEANS OF AËRATING THE WATER THEREIN to be as
follows:-
"
A Cylindrical air chamber made of vulcanized india rubber or other clastic
material having in one end a valve opening inwardly and having in the other end
a small metal or other pipe is enclosed in the hollow handle of a Bait Can. This
handle is of sufficient size to receive the said air chamber. It has a lid or cover
which can be readily opened to allow of the Air Chamber being inserted or
removed when required. This lid has a hole through which the push picco
hereinafter described protrudes when the lid is shut. A plate or piece of wood or
other material sufliciently light and rigid, (concave on its lower surface) is then
shaped to lie on the said air chamber a small button or knob of wood or other
material is then attached to the said first mentioned piece of wood or other
material to act as a push piece, these together form the compressor for the said Air
Chamber, so that it may be worked by the thumb of the person carrying the can.
The small pipe is then laid from the Air chamber down the side and along the
bottom of the Can where it terminates in a rose or pipe distributor. The small
pipe is cut asunder at the hinge of the handle and connected together by a short
piece of indin rubber tubing to allow of the handle being moved to a horizontal
position when desired.
COMPLETE SPECIFICATION.
I BASIL FIELD of Number 30 Lincolns Inn Fields in the County of Middlesex
Solicitor do hereby declare the naturo of my invention for "IMPROVEMENTS IN
BAIT CANS AND THE MEANS OF AERATING THE WATER. THEREIN" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
Fig 1 in the accompanying drawings shows a Bait Can as made according to my
invention. Fig 2 is a section of the handle with the air chamber or bellows,
compressor &c. Fig 3 is a section of the said Air chamber or bellows and vulve

page_text: removed from the handle and Fig 4 is a section of the air valve or distributor.
The cylindrical air chamber or bellows is made of vulcanized india rubber or other
clastic material of the shape (by preference) shewn at A Figs 2 and 3 having in
one end a small valve opening inwardly B Figs 2 and 3 and, in the other end a
small metal or other pipe A Fig 1 and C Fig 2 and is enclosed in the handle of a
Bait Can which is made cylindrical and of suflicient size to receive the said air
chamber or bellows and has a lid or cover thereto at the top or end which may be
readily opened to allow of the said air chamber or bellows being removed when
required The lid or top of the handle as the case may be has a hole through
which the push piece B Fig 1. and D Fig 2 of the Compressor hereinafter
mentioned protrudes. A plate or piece of wood (E Fig 2) or other material
sufficiently light and rigid, concave on its under surface is then shaped to lie on
the top of the said air chaber or bellows and the push piece B Fig 1 and D
Fig 2 is attached to the said plate of wood or other material on its upper side
these together form the Compressor for the said Air chamber so that it may be
worked by the thumb of the person carrying the Can. The pipe A Fig 1 and C
Fig 2 is then carried from the said Air Chamber or bellows down the side and
along the bottom of the Can where it terminates in a Rose or distributor, this Rose
or distributor is shewn in section at Fig 4 in which A is the pin valve to prevent
the back flow of the water when the pressure is removed from the air chamber or
bellows and B is a moveable cover perforated in its circumference with minute
holes to allow of the escape of the air and C is the air pipe. The eduction or air
pipe is cut asunder at the hinge of the handle and the two pieces of metal pipe are
connected together again with a short piece of small india rubber tubing C Fig 1.
to allow of the handle being laid down D Fig 1 is a small staple and nut to secure
the air pipe in its place. The Can is fitted with a Fish Cage of perforated metal
which is removable from the Can when desired by the handlo E Fig 1, the bottom
of the Fish Cage immediately over the Rose or air distributor is formed into a
domo shape and this serves to again break up the bubbles of air after they have
left the Rose:
Having now 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 improvements in Bait Cans consisting of the cylindrical hollow handle
and the placing therein the air chamber or bellows and Compressor and
the arrangement of parts so that it may be worked while the Can is being
carried.
2 The cylindrical air chamber or bellows as applied to aerating Bait Cans.
3 The Rose or air distributor.
4 The dome shaped portion of the bottom of the Fish Cage which acts as an air
bubble breaker.
