Improvements in Card or Sliver Cans.
We, ROBERT HARGREAVES, of Brookhouse Lane, Blackburn, in the County
of Lancaster, Sheet Metal Worker, and GEORGE WHITTAKER HARGREAVES, of
Brookhouse Lane aforesaid, Sheet Metal Worker, do hereby declare the nature
of this invention to be as follows -
This invention relates to improvements in the construction and manufacture
of card or sliver cans having spring or cushion bottoms, the object being to
construct such cans that the bottoms whilst maintaining the requisite elasticity
and spring are not liable to collapse and are more durable owing to the spring
bottom being attached to the can without soldering.
According to this invention the body of the sliver or card can is made às
ordinary and underneath the bottom of the can is the spring or false bottom
made from a sheet of steel pressed as to leave a flange the same circumference
as the bottom of the can. Inside the false bottom and between same and the
bottom of the can is a spring or springs or buffer and the false bottom is held in
position by the binder or strengthening band around the bottom of the can
being prolonged and turned inwards and wired with hard steel wire so that the
flange of the false bottom is held between the wired edge of the binder and the
bottom of the can.

We, ROBERT HARGREAVES, of Brookhouse Lane, Blackburn, in the County
of Lancaster, Sheet Metal Worker, and GEORGE WHITTAKER HARGREAVES, of
Brookhouse Lane aforesaid, 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 and manufacture
of card or sliver cans having spring or cushion bottoms the object being to

page_text: facilitate the manufacture and to construct such cans that the bottoms whilst
maintaining the requisite elasticity and spring are not liable to collapse and are
more durable owing to the loose bottom of the can being held internally instead
of externally and the ring or bottom being in one solid piece without solder.
Such being the nature and object of our said invention the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is a sectional side elevation of the improved sliver can.
Fig. 2 is a sectional side elevation of the several parts constituting the im-
proved sliver can.
Fig. 3 is a plan view and Fig. 4 is an elevation of a modified form of spring or
buffer for the bottom of the can.
According to this invention the sliver or card can 1 is made in the usual manner
and the bottom 2 is preferably slightly concave as shewn. Underneath the
bottom 2 is the spring or false bottom made either from a sheet of steel
pressed or of malleable iron cast or stamped in the form of a ring 3 and a slightly
concave top 4 and flange 5 equal in circumference to the bottom of the can 1.
The spring or false bottom 3 is held in position below the can 1 by means of a
binder or strengthening band 6 the lower edge of which is turned inwards and
wired as at 7 so that the flange 5 of the false bottom 3 rests on the wired ring 7
and the upper portion of the binder or strengthening band 6 surrounds the
lower portion of the body of the can to which it is soldered and permanently
fixed and greatly strengthens the can at its usually weakest part. The false
bottom 3 being held between the wired edge 7 of the binder 6 and the bottom 2
of the can the spring 8 inserted between the two normally holds the spring
bottom in the position shewn in Fig. 1, but in the event of the can being banged
or knocked on the floor, the spring S acts as a buffer and prevents undue wear
and tear.
The improvements are equally applicable to cans for transporting milk and
other goods.
Instead of a spiral spring such as 8, a blade spring or blade springs such as
shewn by Fig. 3 may be employed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we wish it to be
understood that we are aware of Sutcliffe's Specification No. 12,888 of 1889,
and that we claim nothing that is described and claimed therein, but we declare
that what we claim is:
(1) The improved sliver or card can as herein described and substantially as
illustrated by the accompanying drawings.
(2) A can 1 having a false bottom 3 internally suspended in the binder 6 by
means of the wired rim 7 and an interposed spring all in combination as
and for the purpose herein described.
