PROVISIONAL SPECIFICATION.
Improvements in Sliver Cans for use in Spinning Mills.
1, GUIDO STIEHLE of Kempten, (Allgäu,) in the Empire of Germany, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in sliver cans for spinning mills and has
for its purpose to render the same more durable and suitable for their work.
The improved article is made as follows:
A wire of about two or three millimetres thickness is creased into the top and bottom
end of the sheet metal side. Subsequently an iron hollow ring or hook is placed over
each extremity and creased about the wire. In lieu of the stationary bottom heretofor
employed, an easily displaceable loose bottom of pasteboard, wood or other suitable
material is provided, which is supported by the inwardly rounded hollow ring or in
any other convenient manner. The improved device can consequently be used with
either end upward, the loose bottom falling to the opposite end when reversing the
can, thereby removing any reinnants or sliver without necessitating the can to be
knocked as heretofore.

COMPLETE SPECIFICATION.
Improvements in Sliver Cans for use in Spinning Mills.
I, GUIDO STIEHLE of Kempten (Allgäu) in the Empire of Germany Manufacturer
do hereby declare the nature of this invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement:
The object of this invention is an improved sliver can for spinning mills which
is more durable and suitable for work than similar devices hitherto known.
The sliver cans or accumulators of sheet metal heretofore employed wear out
comparatively rapidly owing to the habit of the workmen in case some of the sliver
adheres to the can towards the end of the running out, to turn the can over and let it
fall on the floor until the said rest falls out. Thereby the rivets connecting the ring
with the sheet metal tongue are caused to get loose, or the rings to come off if
soldered on.
Consequently the cans loose their solidity and the rims gradually
become rough and set with obstacles or projecting pieces which have an injurious
effect. The cans therefore have to be frequently replaced by new ones or at least to
undergo many more or less expensive repairs.
In order to remove the said drawbacks, the improved sliver can or accumulator is
constructed as follows, reference being had to Figs. 1 to 4 of the accompanying
drawing:-
--
A wire of about two or three millimeters in thickness is creased in at the top end
and bottom end of the sheet metal edge, Fig. 2. Subsequently a hollow ring is
placed over each end and creased about the said wire. This construction ensures a
by far greater solidity of the can than heretofore and the tearing out of rivets and
thereby frequency of repairs are effectively obviated. As shown in Fig. 4 a groove h
or several of such running parallel or obliquely may be pressed into the metal
rings in order to increase their resistant capacity. Beside the application of the
hollow metal rings, the improved sliver can is provided with a loose easily displaceable
flat or vaulted bottom in lieu of the stationary bottom heretofore employed. This

page_text: bottom a bears on the hollow ring b which is rounded inwardly or fitted with a pro-
jection. The application of said loose bottom leads to the great advantage that the
can need not be knocked on the floor or otherwise for removing remnants or sliver,
which is done by own weight of the loose bottom without any thrusting of the can.
Moreover the groove or grooves mentioned above prevent the bottom from falling
down beyond the same. When however the said groove or grooves is or are dispensed
with, the loose bottom allows the sliver can to be used with either end upwards which
cannot be done with sliver cans having a stationary bottom.
The hollow metal ring is represented in Fig. 1. in cross section as it is shaped
prior to its being secured to the sheet metal edge which latter is shown in Fig. 2
Fig. 3 is a cross section of the closed hollow ring and
Fig. 4 of the hollow ring provided with a groove and connected with the sheet
metal edge and carrying the loose bottom.
with the wire creased in.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
1) A sliver-can or accumulator for use in spinning mills adapted to be employed
with either end upward, the bottom being arranged movable between interior
stiffenings or projections of the rims substantially as and for the purpose set
forth.
2) For the purpose of stiffening or strengthening the ends of the sliver can
forming the subject of claim 1, the application of hollow metal rings 6 which may
or may not be provided with a groove or grooves and are creased over the
ends of the sliver can and rounded inwardly substantially as set forth.
