IMPROVE- MENTS IN CUTTING PLASTIC TUBES OR TILES
Year: 1849

page_text: WILSON'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WILSON, Junior, of Campbellfield, Glasgow, in the County of Lanark, Scotland,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-seventh day of
June, One thousand eight hundred and forty-nine, in the thirteenth year of
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Wilson, my exors, adñññors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said William Wilson, my
exors, adñors, and assigns, or such others as I, the said William Wilson, my
exors, adññiors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,
should and lawfully might. make, use, exercise, and vend, within England
and Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN CUTTING PLASTIC TUBES OR TILES;" in which said Letters Patent is
contained a proviso that I, the said William Wilson, should cause a particular
description of the nature of my said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, to
be inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Wilson, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully described-and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews an apparatus partly in section arranged suitably for carrying
out my Invention. Figure 2 shews an end view thereof.
Figure 3 is a view looking into the ends of the horses which receive the
tubes or tiles as they are formed, and Figure 4 is an end view shewing the
wheel-work and parts which give motion to the cutters. a, a, are two horses
to receive two tubes or tiles as they are formed in coming through suitable
dies, as is well understood. These horses are hollow in order to admit of the
apparatus which I employ for cutting the tubes. bis the handle by which the
workman holds the horses in position to receive two tubes or tiles as they are
being formed, and when a proper length has been received on each horse, the
process of cutting is to be performed, and which I prefer to be done in the
following manner. c, c, are two axes which have each a cog wheel d thereon,
which takes into and is driven by the cog wheel e, the cog wheel e having
plates, e¹, on either side so as to move the wheels d and their axes to and fro
when it is caused to move to and fro by incans of the wheelf on the axis 9.
This wheel has part of its periphery formed into inclines, and only part of its
periphery has teeth as shewn. On the axis of the cog wheel e is a pinion, h,
there being plates on either end of the pinion, so that it may be capable of
moving to and fro when acted on by the inclined portions of the wheel f.
The axes c, c, each carries a cutter i, the shape of which may be varied
according to the figure of the socket or concave end desired to be obtained by
the cut.
Figure 5 shows various shapes of cutters which may be employed, and what-
ever be the cutter used it is fastened to the bent lever j, the other end of the
lever passing through a slot in the end of the axis c, as shewn. The bent lever
is carried by a circular plate k, which is caused to turn by the rotation of the
axis c, as will readily be understood on examining the Drawings. The work-
man having, as before stated, received two tubes on the two horses, he will
cause them to be cut off by turning the handle l, which in the first place by
the rotation of the wheel f forces the axes c, c, outwards, the effect of which
will be to cause the cutters to protrude through the plastic tubes or tiles, and
the continued rotation of the handle will cause the cutter axes c, c, to revolve,
and thus cut the tubes or tiles which are on the horses off the other parts, thus
making the ends so cut of the tubes or tiles on the horses to be convex, whilst

page_text: the ends of the next coming tubes or tiles will be concave or socket ends, or
vice versâ, according to the position in which the cutters may be fixed, and
thus the convex end of one pipe will be suitable for entering the concave or
socket end of the other. The still further rotation of the handle will then draw
the axes inwards, and cause the cutters to fall back into their original position,
and thus admit of the tubes or tiles being removed from the horses.
Figure 6 shews a longitudinal view of the concave and convex ends of tubes
cut as above described by the cutter represented in Figure No. 1; but the
form of the cut will vary according to the form or position of the cutters
employed.
I would state that although I prefer the arrangement above described for
cutting the end of one tube or tile out of the other, I do not confine myself
thereto so long as apparatus is so managed that in cutting or separating tubes
or tiles one from the other they shall one have a hollow or concave end or cut,
and the other a convex end or cut to correspond as herein explained; and
although I prefer to cut from the interior, an apparatus might be made to cut
in like manner from the outside. And further, although the above apparatus
is exhibited as cutting two tubes or tiles simultaneously, the machines may be
so constructed as to cut one or more at a time. What I claim as my
Invention is the so arranging apparatus for cutting plastic tubes or tiles that
their ends may be cut one out of the other, the one having a concave or
hollow end or cut, and the other a corresponding end or cut suitable for entering
into the same as explained.
In witness whereof, I, the said William Wilson, Junior, have hereunto
set my hand and seal, this Tenth day of December, in the year of our
Lord One thousand eight hundred and forty-nine
(L.5.)
NN, JUNIOR.
AND BE IT REMEMBERED, that on the Tenth day of December, in the
year of our Lord 1849, the aforesaid William Wilson, Junior, came before
our said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according to
the tenor of the Statute made for that purpose.
