WILLIAM CALVERT, of Leeds, in the County of York. "IMPROVEMENTS IN CAN'S
OR OTHER RECEPTACLES FOR FLAX, COTTON, SILK, JUTE, AND OTHER 'SLIVERS.''
My Invention consists in the employment of a reversable can or other receptacle
constructed in such a manner that the "sliver" may be run into it at one end and
drawn out at the other, so that the fibre may be always worked and layed in one
direction undisturbed, consequently a stronger, much smoother, and superior thread
is produced from the "sliver."
To effect the above purpose, instead of having a fixed bottom, as in the cans now
in use, I provide a loose one, which may be changed from one end of the can to the
other. When the can has been filled with "sliver" it is passed on for the next
operation, the loose bottom being transferred by the attendant to the other end of
the can, and the can reversed, that is to say, that end of the can which was the
bottom for one machine is reversed and becomes the top for the next, consequently
the "sliver" always runs in one direction.

Figure 4, a plan of the other or bottom end of the can, with false or loose bottom
shewn in position.
· Figure 5 is a plan of false or loose bottom.
a is a can of ordinary construction. Instead of having a fixed bottom at b, as in
the cans now in use, I provide a loose one c, which may be changed from one end of
the can to the other at pleasure, both ends being arranged to receive it by having
fixed therein the flanged rings d, and projecting pieces e fixed thereon for the
purpose of retaining the loose or false bottom in position. The false bottom c is
constructed as shewn at Figures 5 and 2, one or more recesses of being provided
therein to pass the lugs or projecting parts e.
After the false or loose bottom is
dropped on to the flanged ring at d a twist is given thereto so as to bring the recess
or recesses of clear of the projecting parts e, as shewn in Figure 4; this having been
done, the false or loose bottom is firmly fixed in position.
In my Drawings I have only shewn one arrangement as applied to "sliver" cans of
ordinary construction, but it will be clearly understood and obvious that other loose
or false bottoms, capable of being changed from one end of the receptacle to the
other, may be used without departing from my Invention.
When the can or other receptacle has been filled with "sliver "it is passed on for
the next operation, the loose bottom being transferred by the attendant to the other
end thereof, and fixed in the manner herein-before described, and the can reversed,
that is to say, that the end of the can or other receptacle which was the bottom for
one machine is reversed and becomes the top for the next, consequently by this
means the "sliver" may always run in one direction, and the fibre thereof always
worked and laid in that direction undisturbed, consequently stronger and much
superior thread is produced therefrom.
I
Having thus described the nature of my said Invention and the means by which
carry the same into effect, I would have it understood that I do not limit myself

page_text: to the exact details and configurations of the various parts I have explained and
shewn, but what I claim and desire to be secured to me by Letters Patent is,-
Firstly. The employment of a loose bottom capable of being changed from one
end of a "sliver," can, or receptacle to the other, for the purpose herein set forth.
Secondly. Constructing the ends of "sliver" cans or receptacles in such a manner
that a false or loose bottom may be fixed at either end, and changed from either
end to the other, for the purpose herein set forth.
In witness whereof, I, the said William Calvert, have hereunto set my hand
aud seal, this Eighteenth day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
