Year: 1872

page_text: LETTERS PATENT to William Ambler, of Bradford, in the County of
York, Patent Agent, for the Invention of "IMPROVEMENTS IN MA-
CHINERY FOR THE MANUFACTURE OF PAPER TURES"
Sealed the 18th February 1873, and dated the 21st August 1872.
PROVISIONAL SPECIFICATION left by the said William Ambler at the
Office of the Commissioners of Patents, with his Petition, on the
21st August 1872.

I, WILLIAM AMBLER, of Bradford, in the County of York; Patent
Agent, do hereby declare the nature of the said Invention for " IMPROVE-
MENTS IN MACHINERY FOR THE MANUFACTURE OF PAPER TUBES," to be as
follows:-
This Invention relates to a peculiar construction and arrangement of
machinery or apparatus for the manufacturing of paper tubes with extra-
ordinary speed and economy. To accomplish this I provide a reel of
paper of suitable width for the length of the tubes to be made, and
which I place conveniently above the machine. The loose end of this I
pass between a pair of rollers, which draw forward the paper for cutting
into various lengths, according to the number of laps required in the
tube, after which it passes before a revolving cutter, which severs off the

page_text: required lengths, each of which is immediately drawn forward between
two rollers, one of these rollers being segmental or eccentric and covered
with india-rubber or felt, the other being immersed in paste and working
in close contact with the india-rubber roller. By this means the paper
becomes pasted and laid upon the segmental or eccentric part of the
roller, which in revolving forward comes in contact with a spindle or
mandril upon which the tube is to be made, and to which the pasted
paper now adheres, the quicker revolution of the spindlo taking it up
from the segmental roller. The spindle and segmental part of the roller
continue revolving together until the tube is formed, when the segmental
or full eccentric part having passed the spindle, leaves room for a collar
upon the spindle to be pushed forward, thrusting off the tube, motion
being given to the collar by means of a tappet or cam, which causes the
collar to return in time for the next tube.
Motion is given to the machine by means of a strap driving the
machine at the rate of 200 or more revolutions per minute, and pro-
ducing a tube at each revolution.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Ambler in the Great Seal Patent Office on
the 21st February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
AMBLER, of Bradford, in the County of York, Patent Agent, send
greeting.
WHEREAS 1er most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of August, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Ambler, Her special licence that I,
the said William Ambler, my executors, administrators, and assigns, or
such others as I, the said William Ambler, my executors, administrators,
and assigns, should at any time agree with, and no others, from time
to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR THE

page_text: roller, sec dotted lines, Figure 2, for the passage of a loose collar L along
the spindle, which thrusts the tube off, the said collar being actuated by
a tappet and cam groove M, which causes it to return immediately, so as
not to impede the making of the succeeding tube. The pressure of
contact between the roller E and spindle K is regulated by the excentric 5
motion shown at P.
In order to facilitate the pushing off of the tube from the split spindle
one portion thereof is made fast and the other loose or movable, sec
Figure 1. The movable portion consists of two brass slips N, working
longitudinally or backwards and forwards in grooves in the fast portion. 1
The forward motion facilitates the propulsion of the tube from the
spindle at the time the collar L is commencing to push it off, thus
reducing the friction by one half, the slips being actuated by a spring O,
and moved back by the return of the collar.
Motion is given to the machine by means of a leather strap driving 1
the machine at the rate of two hundred or more revolutions per minute,
and producing a tube at each revolution.
Having now described the nature and object of my said Invention for
"Improvements in Machinery for the Manufacture of Paper Tubes," .
together with the manner in which the same is to be or may be por- 2
formed or carried into practical effect, I would remark in conclusion
that I claim as my Invention, the improved construction and peculiar
arrangement of machinery or apparatus for manufacturing paper tubes,
particularly the cutting arrangement, the eccentric roller, and the split
spindle, substantially as above described and as illustrated on the accom- 2
panying Drawings, or any equivalent modification thereof.
In witness whereof, I, the said William Ambler, have hereunto sct
my hand and seal, this Eighteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-three.
