IMPROVEMENTS IN CHAIN BEAMING APPARATUS
Year: 1867

page_text: LETTERS PATENT to John Pinkerton Kerr, Manufacturer, and William
McGee, Engineer, both of Paisley, in the County of Renfrew, North
Britain, for the Invention of "IMPROVEMENTS IN CHAIN BEAMING
APPARATUS."
Sealed the 13th August 1867, and dated the 15th February 1867.
PROVISIONAL SPECIFICATION left by the said John Pinkerton Kerr and
William McGee at the Office of the Commissioners of Patents, with
their Petition, on the 15th February 1867.
We, JOHN PINKERTON KERR, Manufacturer, and WILLIAM M°GEB, Engi-
neer, both of Paisley, in the County of Renfrew, North Britain, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CHAIN BEAMING
APPARATUS," to be as follows, that is to say:-
This Invention has for its objects the rendering of chain beaming apparatus
more automatic, and the obtaining of a more uniform beaming action than
hitherto.
The features of novelty are the application of gearing so as to work the
drag or tension rollers by power with a reverse motion when it is necessary to
take back the chain; the application of a deliverer or folder in connection with
the drag or tension rollers to deliver the chain clear of the rollers, and in a
convenient manner; and the application of movable frictional driving gear to

page_text: the beam to vary its revolutions so as to obtain a more uniform surface speed
with the varying diameter of the yarn on the beam.
In carrying out the Invention according to one modification fast and loose
pulleys are put on the shaft of one of the tension rollers to receive a belt from
an overhead shaft arranged to drive the rollers in the direction for taking
back. A fork for shifting the belt is carried by a shaft having a handle on
it convenient to the beamer's hand. The gearing applied to drive the beam
for winding on is arranged with any convenient clutch, and there is in con-
nection therewith a treadle as in ordinary beaming apparatus on which the
beamer has to press to keep the beam winding on; when, however, the taking
back motion is working, the treadle is kept up by a lever on the shaft that
throws the taking back motion into or out of gear. When taking back the
beam is left free in order to avoid strain on the yarn. To deliver the chain
clear of the tension rollers, and to fold or lay it conveniently, a revolving
paddle or a reciprocating bar over which the chain passes is arranged in gear
with the tension rollers. The tension rollers instead of being driven by a belt
as described, may be driven by spur, bevil, or screw gearing in connection
with the driving details of the beam.
. For the purpose of driving the beam with a uniform surface speed there is
on a shaft coupled to or in gear with the beam a disc which is driven by a
pulley on a shaft at right angles thereto, and this pulley is arranged on its
shaft with a key and groove so that it can be shifted on it to act at different
radii of the disc. The driving pulley may be shifted by hand by means of
levers, or by a screw or other slow motion from the driving shaft itself, or by
means of levers acted on by the yarn itself on the beam.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Pinkerton Kerr and John McGee in the Great
Seal Patent Office on the 14th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
PINKERTON KERR, Manufacturer, and WILLIAM MOGEE, Engineer, both of
Paisley, in the County of Renfrew, North Britain, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Pinkerton Kerr and William McGee, Her special licence that

page_text: we, the said John Pinkerton Kerr and William McGee, our executors, admi-
nistrators, and assigns, or such others as we, the said John Pinkerton Kerr
and William McGee, our 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 "Im-
PROVEMENTS IN CHAIN BEAMING APPARATUS," upon the condition (amongst
others) that we, the said John Pinkerton Kerr and William M°Gee, our
executors or administrators, by an instrument in writing under our, or one
of our or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the John Pinkerton Kerr and William
M'Gee do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement in writing, reference being had to
the accompanying Drawings, that is to say :-
Our said Invention has for its objects the rendering of chain beaming
apparatus more automatic, and the obtaining of a more uniform beaming
action than hitherto.
The principal features of novelty of our said Invention are:-The application
of gearing so as to work the drag or tension rollers by power with a reverse⚫
motion when it is necessary to take back the chain; the application of a
deliverer or folder in connection with the drag or tension rollers to deliver the
chain clear of the rollers and in a convenient manner; and the application of
movable frictional driving gear to the beam to vary its revolutions, so as to
obtain a more uniform surface speed with the varying diameter of the yarn on
the beam. It is an important advantage of our improved apparatus that it
can be managed by a single beamer without assistance.
:
And in order that our said Invention and the manner of performing the
same may be properly understood, we have hereunto appended a Sheet of
explanatory Drawings to be berein-after referred to, and representing beaming
apparatus as made with modifications of our improved arrangements.
Figure 1 is a front elevation, and Figure 2 is a side elevation of the
apparatus.
Figure 3 is a back elevation of a part not seen in Figure 1, and Figure 4.

page_text: is a front elevation showing a modification of driving gear differing from that
seen in Figure 1. The same reference numerals are used to mark the same
or like parts in all the Figures.
The driving
The beaming apparatus comprises as usual, two frames, 1, 2, placed a short
distance apart, the front frame 1 carrying the beam 3, on which the chain 4,
colored blue in the Drawing is to be wound, whilst the other frame 2 carries
the tension rollers 5, 6, round which the chain 4 first passes. The chain 4 is
passed a number of times round the tension rollers 5, 6, in the usual way, and
then goes back to a pulley 7 on a standard 8, whence it returns above the
roller frame 2 forward to the front frame 1. Just before reaching the front
frame 1; the chain 4 passes through a reed 9 suspended by cords, and it then
passes through the principal reed 10 fixed across the top of the frame 1, and
thence round a small guide roller downwards to the beam 3.
gear for the beam 3 consists of a first-motion shaft 11, which has on it a
pulley 12 actuated by a belt from an overhead shaft, and two toothed wheels
18, 14, of different sizes in gear with corresponding toothed wheels 15, 16,
on a second-motion shaft 17 below. The pulley 12 is loose on the shaft, but
is formed with a grooved boss acted on by a lever 18, by which lever it can be
put into contact with a pulley fast on the shaft. The pulley 12 completely
covers the fast pulley as seen in Figure 1, and the two are formed with disc-
like or other suitable surfaces to drive by frictional contact. The wheels 15,
16, are loose on the second motion shaft 17, but by a clutch 19 between them
either can be put into gear according as the one or the other speed is wanted.
The second motion shaft 17 is in line with the beam 3, and is arranged to
drive it in the ordinary way. Hitherto the tension rollers 5, 6, have not been
driven, but by the present Invention the shaft 20 of the upper roller 5 is
extended on one side as best seen in Figure 3, and is fitted with fast and loose
pulleys 21, to receive a belt from an overhead shaft, arranged to drive the
rollers in the direction for taking back. A forked lever 22 for shifting the
belt is carried by a horizontal shaft 23, which extends forward to the front
frame 1, and which has a hand lever 24 on its front end disposed conveniently
for the beamer's hand. There is a treadle 25 as in ordinary beaming apparatus,
on which the beamer has to press to keep the beam winding on, this treadle
being connected to a horizontal lever 26, which by means of a pin acting in an
inclined slot in the lever 18 puts the driving pulley 12 into gear. The lever
26 is weighted so as to put the pulley 12 out of gear, when the beamer takes
his foot off the treadle 25, and when the taking back motion is put in action
by means of the hand lever 24, a lever 27, on the same shaft 23, and with a
pin fixed to it, holds the lever 26 in the position for keeping the pulley 12 out of

page_text: gear, so that the two motions which are in opposite directions cannot be in
action simultaneously. When taking back the beam 3 is quite free, to turn
so that there is then no strain on the yarn. When the chain is being taken
back it is necessary for it to be delivered clear of the tension rollers 5, 6, and
to effect this a small paddle 28 is carried in brackets at the back of the
tension roller frame 2, and is driven by means of a belt from the shaft of one
of the tension rollers 5; this paddle 28 lays or folds in a convenient manner.
whatever slack is formed in the chain by the taking back action; the same.
thing might however be effected by a reciprocating or vibrating, bar actuated
by an eccentric on one of the roller shafts. The lower tension roller 6 is.
driven by a belt 29 from the shaft 20 of the upper roller. 5. Instead of.
these tension rollers 5, 6, being driven by belts as described, they may be
driven by spur, bevil, or screw gearing in connection with the driving details
in the front frame 1 for actuating the beam.
In order to facilitate the introduction and removal of the beam 3, two hooked
levers 30 are provided, being fixed on a shaft 31, on one end of which there is a
worm wheel 32 in gear with a worm on an inclined spindle 33, having a handle
on its upper end. By means of these levers 30, the beam 3 can be lifted into a
position convenient for its being removed by hand or on a carriage; the beam
3 is placed, as shown, in a much more convenient position than hitherto, and
this advantage is a consequence of the other improved arrangements. In
our arrangement for applying frictional driving gear, shown in Figure 4, there
is a disc 34 on a shaft 11 corresponding to the first motion shaft in the
arrangement herein-before described, and this disc 34 is driven by a pulley 35
on a vertical shaft 36, actuated by bevil gear from an overhead shaft. The
pulley 35 is arranged on its shaft with a key and groove, so that it can be
shifted on it to act at different radii of the disc 34, by means of a forked
bell crank lever 37. A screw spindle and hand wheel 38 is represented for
adjusting the lever 37 by hand; it may however be arranged to be adjusted by
a screw or other slow motion from the driving shaft itself. The disc 34 is
fitted upon its shaft 11 with a groove and key, but is otherwise loose so that
it can be moved into driving contact with the pulley 35, or away therefrom
by the lever 18 actuated by means of the lever 26 and treadle 25, as in the
other modification.
Having thus particularly described our said Invention and the mauner in
which the same is to be performed, we have to state that we do not restrict
ourselves to the precise details herein described or delineated, but that what
we believe to be novel and original, and claim as the Invention secured to us
by the herein-before in part recited Letters Patent is,-

page_text: 1. The application in beaming apparatus of gearing to work the drag or
tension rollers by power with a reverse motion for taking back, substantially as
herein-before described.
2. The adapting of a paddle or reciprocating folder or layer to deliver the
chain clear of the tension rollers substantially as herein-before described.
3. The adapting of frictional gearing for driving the beam, such gearing
being adjustable by hand or by a slow motion from the beam shaft substantially
in the manner herein-before described. And,
4. Generally, the arranging or combining together of the various parts of
the apparatus, so as to be conveniently and easily managed by a single beamer,
substantially as herein-before described.
In witness whereof, I, the said John Pinkerton Kerr, on behalf of myself
and of the said William McGee, have hereunto set my hand and
seal, this Thirteenth day of August, in the year of our Lord One thou-
sand eight hundred and sixty-seven.
