PROVISIONAL SPECIFICATION.
Improvements in or relating to Carding and other similar Cans.
I, AARON LEVER of 82 Davenport Street, Bolton in the County of Lancaster,
Tinplate Worker, do hereby declare the nature of my said invention to be as
follows:-
:―
This invention refers to improvements in or relating to carding and other similar
cans employed in connection with carding engines, drawing frames, and other
machines in the process of preparing cotton and other fibrous substances, and is
designed to strengthen the bottom of same to prevent or minimise the risk of the
bottom being knocked out by the rough usage they are subjected to in being moved
from one machine to another. This I effect by constructing the bottom with an
inside annular recess to receive the projecting flange of the can bottom. The
annular recess is formed by bending or turning the bottom end inwardly for a
certain distance, and then outwardly for a shorter distance, the latter forming the
recess to receive the projecting flange of the can bottom. After the can bottom
has been fitted in position in the annular recess it is secured by an internal inetallic
ring rivetted through the double portion of the bent end of the bottom, after which
they are further secured by soldering or other similar means both inside and outside
for any desired distance. The bottom end of the can proper rests on the upper side
of the internal projection formed by the annular recess, thus making a complete
even surface, which is essential to protect the "sliver" in the process of preparing
cotton and other fibrous substances.

COMPLETE SPECIFICATION.
Improvements in or relating to Carding and other similar Cans.
I, AARON LEVER of 82 Davenport Street, Bolton in the County of Lancaster,
Tinplate-Worker, do hereby declare_the_nature_of my said 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 refers to improvements in or relating to carding and other similar
cans employed in connection with carding engines, drawing frames, and other
machines in the process of preparing cotton and other fibrous substances, and is
designed to strengthen the bottom of same to prevent or minimise the risk of the
bottom being knocked out by the rough usage they are subjected to in being moved
from one machine to another. This I effect by constructing the bottom with an
inside annular recess to receive the projecting flange of the can bottom. The
annular recess is formed by bending or turning the bottom end inwardly for a
certain distance, and then outwardly for a shorter distance, the latter forming the
recess to receive the projecting flange of the can bottom. After the can bottom
has been fitted in position in the annular recess it is secured by an internal metallic
ring rivetted through the double portion of the bent end of the bottom, after which
they are further secured by soldering or other similar means both inside and outside
for any desired distance. The bottom end of the can proper rests on the upper
side of the internal projection formed by the annular recess, thus making a complete

page_text: even surface, which is essential to protect the "sliver" in the process of preparing
cotton and other fibrous substances.
Fig. 1 is a sectional elevation of the bottom of a carding or other similar can
constructed on my improved principle, and Fig. 2 is a part sectional elevation of
outer rim bent to receive can bottom.
The outer rim A of the bottom part of the carding or other similar can is
provided with the annular recess B formed by bending the bottom end inwardly
for a certain distance, then outwardly for a shorter distance, the latter forming the
annular recess B as shown in Fig. 2. The can bottom C is of the form shown in
Fig. 1 with its outer edge turned or bent upwards, which is fitted or placed in the
annular recess B, after which it is held therein by the internal metallic ring D
secured by rivets E of any suitable number according to the diameter of the can.
After the bottom C and ring D have been fixed in position they may be further
secured by soldering or other similar means both inside and outside for any desired
distance. The bottom end of the body H-forming the can proper is placed
inside the outer rim A and rests on the upper side of the internal projection I
formed in constructing the annular recess B as shown in Fig. 1.
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 :-
In combination with carding and other similar cans the use and construction of
the outer rim A provided with the annular recess B to receive the can bottom C,
the latter being secured by the internal ring D rivetted and soldered to secure the
whole in position, substantially as described and as illustrated in the annexed
drawings.
