Improvements in Sliver Cans.
I, RICHARD PARKER, of Heapey Copper Works, Heapey, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this invention to be
as follows: —
This invention is designed to provide a sliver can that will be stiffer, stronger
and more durable than many of those at present in use.
The base and top of the can are formed and fitted in any ordinary way but
preferably as described in the specifications of my former patents No. 8501 of
1897 and No. 5815 of 1898.
The body or central part of the can I emboss with a number of grooves or
channels preferably raised from the inside one set running circumferentially
of the can and the other set longitudinally and crossing the circumferential
grooves or channels forming a diamond or similar pattern on the can where the
grooves cross.
The circumferential grooves are preferably smaller or narrower near the top
of the can than at the bottom the grooves gradually increasing in size from the
top to the bottom.
The longitudinal grooves preferably do not extend the whole length of the
can but about half the length some being longer than others. These grooves
may taper if desired being wider, broader and deeper at the bottom than at the
top.
"In some cases the tapered longitudinal grooves may run up to the top of the
can and will give sufficient stiffness at the bottom without the circumferential
ones. Or the longitudinal ones may run the full length and circumferential
ones be applied only at the bottom.
I prefer to make the grooves by means of rollers applied after the cans are
made and they may also be applied to old or existing cans or the sheets may be
grooved before being made up.

Improvements in Sliver Cans.
I, RICHARD PARKER, of Heapey Copper Works, Heapey, in the County of
Lancaster, Machine Maker, 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 is designed to provide a sliver can that will be stiffer, stronger
and more durable than many of those at present in use.

page_text: The base and top of the can are formed and fitted in any ordinary way but
preferably as described in the specifications of my former patents No. 8501 of
1897 and No. 5815 of 1898.
The body or central part of the can I emboss with a number of grooves or
channels preferably raised from the inside one set running circumferentially
of the can and the other set longitudinally and crossing the circumferential
grooves or channels forming a diamond or similar pattern on the can where the
grooves cross.
The invention will be fully described with reference to the accompanying
drawings;-
-
Fig. 1. Side elevation of sliver can.
Fig. 2. Side elevation of a modification.
Fig. 3. Sectional plan applicable to either Fig. 1 or Fig. 2.
The can A is embossed from the inside with two sets of grooves B and C
one set annular and the other longitudinal with the space a of diamond shape
between.
In Fig. 1 the longitudinal grooves C are shown as of alternate lengths and
each alternate groove running to nearly the top of the can while in Fig. 2 they
are shown of varying length and extending over only a part of the length of
the can.
The length and arrangement of the longitudinal grooves may be varied
as desired either for the sake of appearance or otherwise.
The annular or circumferential grooves B may be made smaller or narrower
near the top of the can than at the bottom the grooves gradually increasing in
size from the top to the bottom.
The longitudinal, grooves C may be made to taper if desired being wider,
broader and deeper at the bottom than at the top.
In another modification the longitudinal grooves may be made tapering from
the base to the top of the can and thus give the desired stiffness at the bottom
without the circumferential ones. Or the longitudinal ones may run the full
length and circumferential ones be applied only at the bottom.
I prefer to make the grooves by means of rollers applied after the cans are
made and they may also be applied to old or existing cans or the sheets may be
grooved before being made up.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A silver can constructed with a set of annular grooves and a set of longi-
tudinal grooves crossing at right angles to give increased stiffness to the body
of the can substantially as described.
2. A sliver can constructed with a number of annular or circumferential grooves
decreasing in size from the bottom upwards to give increased stiffness to the body
substantially as described.
3. A sliver can constructed with a number of longitudinal grooves tapering
from the bottom upwards to give increased stiffness to the body substantially as
described.
4. A sliver can constructed substantially as described.
