.Improvements in Sliver Cans.
I JAMES ANDERTON SUTCLIFFE of Sumner Street, Islington Blackburn, Sheet
Metal Worker do hereby declare the nature of this invention to be as follows:-
A novel invention for preventing the bottom ring or bottom of a card or sliver
can from being broken or injured by being thrown down on the floor & thereby
causing also the body of the said can to telescope just above the binder of the
said can.
This invention will obviate the shock when being dropped on the floor. I employ
a kind of buffer arrangement so that when dropped on the floor the force is taken
up by a spring or by compression of air or by any kind of material that will
act as a buffer & obviate the shock to the body of the can when being dropped
on the floor.

COMPLETE SPECIFICATION.
Improvements in Sliver Cans.
I, JAMES ANDERTON SUTCLIFFE of Sumner Street, Islington, Blackburn, Sheet
Metal Worker, do hereby declare the nature of this 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 relates to improvements in the construction of sliver cans the object
being to prevent the bottom ring or bottom of the sliver can from being broken or
injured by being thrown or dropped down on the floor and thereby causing also
the body of the said can to telescope just above the binder.
According to my invention I obviate the shock which usually occurs when a
sliver can is dropped or thrown upon the floor, by employing a kind of buffer
arrangement so that when dropped or thrown upon the floor, the force of the
blow is taken up by a spring, or by compression of air, or by any kind of material
that will act as a buffer and obviate the shock to the body of the can when being
dropped or thrown on the floor.
In the accompanying drawings, in all the Figures of which the same or similar
parts are indicated by like reference letters. Figure 1 is an elevation and Figure 2
is a sectional view of the lower part of a sliver can made in accordance with my
invention.

fitting into the iron ring A; D is also a flanged rim fitting inside the rim C and
firmly secured to the bottom E. The flanges of the rims C and D are kept in
contact by a spring F which is compressed so as to exert a pressure between the
bottom E and the false bottom B. G is a piece of compressible material placed
between the flanged rim C and the bottom E thereby forming a cushion or
auxilliary buffer for the rim C to bear against in case of a blow sufficient to
overcome the outward pressure exerted by the spring F.
It is obvious that the convolute spring F, which I prefer to make of steel, may
be replaced by any compressible material. The air enclosed between the bottom E
and the false bottom A may alone suffice if the parts be closely fitted in order to
allow very little leakage and so to provide an air cushion to be more or less

iron ring A.
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
A sliver can having a false bottom performing the function of a buffer sub-
stantially as described and shown in the accompanying drawings.
