of the Commissioners of Patents, with his Petition, on the 25th
February 1870.
I, JOHN BULLOUGH, of the Firm of Howard and Bullough, Machine
Maker, of Accrington, in the County of Lancaster, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN WARPING OR
BEAMING AND SIZING MACHINES," to be as follows:-
The object of my Invention is to enable such operations as "doffing,"
putting in lease bands, cutting off lappers, and the like to be performed
without stopping the machine. To accomplish this I put a worm wheel on
the end of the nine inch wood roller. This worm wheel is loose on the
shaft, but a catch which is hanging from the side thereof is put in gear
with a ratchet wheel which is fast on the shaft. Motion is given to this
worm by means of a short shaft driven from the first motion or any other
convenient part of the machine. When the machine is going at its
ordinary working speed the catch wheel on the end of the nine inch
roller overruns the catch and the worm wheel to which the catch is
attached. When any of the operations above named is to be performed

page_text: the strap on the first motion pully is not disturbed, but the weaver's
beam is stopped by disconnecting the gearing which drives it or in any
other way, and in cases where the nine inch roller is driven independently
of the winding on motion the means of driving it are put out of action
simultaneously with the action for stopping the weaver's beam.
So soon
as the effect of these movements reduces the speed of the nine inch
roller to a point below that of the worm wheel and catch, which being
driven from the first motion shaft remains at the same speed as before,
the catch becomes the driver of the catch wheel, the nine inch roller to
which it is fixed, and through it of the cylinders, size rollers, and back
beams. Thus the whole machine with the exception of the winding on
is kept in motion. But it is obvious that some provision must be made
for keeping the yarn straight which is given out by the nine inch roller
during the time the winding on is stopped. For this purpose I employ
a roller which I place on the under side of the yarn behind the nine
inch roller, and I give an upward tendency to it by attaching to cach
end thereof a chain and carrying it over a conducting pulley as high
above the machine as convenient, and attaching a weight to the other
end of it. The tension of the yarn in ordinary working overcomes these
weights and so keeps the roller down to its bearings, but when that
tension is taken off owing to the winding on being stopped and the nine
inch roller continuing in motion the roller rises and takes up the yarn
given out and keeps it straight. In order to prevent the upward motion
of the roller resisting the effort of the sizer to carry the full beam back
and otherwise to inconvenience him while " doffing," I place a roller
slided true, covered if necessary with flannel or india-rubber, on the
breast beam roller as a nipping roller, thereby cutting off the influence
of the rising roller from the threads on the other side of these rollers
and enabling the sizer to doff without inconvenience, of course there is
no limit to the height the roller can rise except on the score of con-
venience. The higher it is allowed to rise the more time will the sizer
have to perform the various operations named. A series of rollers may
be employed to give more time still, and in such a case the difference
between the ordinary working speed and the diminished speed would be
less than when the time was very little, owing to their being only one
roller. To prevent a possibility of accident in the event of the sizer not
having recommenced winding on before the roller rises to its limit, I
place a tumbler for the weight to act on when it gets so low as corrc-

page_text: sponds with a very high position of the rising roller, and this tumbler
communicates with the strap fork of the first driver and forces the strap
from the fast to the loose pulley, and so stops the entire machine.
I make a further use of this rising roller. In some cases it is desired
to put stress on the yarn to make a hard beam, or for other purposes,
and I obtain any required stress by simply increasing the balance
weights.
Another use I make of it is in the case of machines in which the
weaver's beam is driven by friction. In such cases it is very common
for the friction to have more power in it than necessary for what it is
intended to do, and the yarn suffers in consequence by having extra
stress put upon it. I propose to let my rising roller rest in moveable
bearings forming one end of double levers working on a pivot or fulcrum
fastened to the frame of the machine. The other end of the levers is
weighted with a sliding weight. This sliding weight is moved to a
distance from the fulcrum to correspond with the amount of stress it is
desired to put upon the yarn. If the friction is screwed up too much
it will put more stress on the yarn, and in so doing will depress its
bearings and raise the opposite arms of the levers and the weights which
they carry, and this will serve as an indicator to the sizer that his friction
is too powerful, and he will ease it till the arms and weights fall to
their horizontal position, which position indicates to the sizer an amount
of friction which is not excessive.
My next improvement relates to the warping or beaming machine,
and consists in making the ordinary conducting roller act also as a
measuring roller. By the conducting roller I mean that roller which
is sometimes placed for the yarn to run over on its way to the front
comb, and sometimes in the front of the comb to guide the yarn on to
the beam. I arrange the parts of the measuring apparatus so that they
may be actuated by this roller instead of by the ordinary measuring
roller. By this means the ordinary measuring roller is dispensed with,
the conducting roller fulfilling the two purposes of measuring and con-
ducting. The machine is simplified by the roller thus dispensed with,
and the space that roller occupied is saved and the yarn also has less
stress upon it owing to its having one roller fewer to turn.
My next improvement relates to the pin box, and consists simply in
making greater facility for the escape of dirt or "fluke" through the
slots or grooves in which the stems of the faller pins work. The grooves

page_text: are formed by two bars placed nearly in contact face to face and of a
depth a little less than the stem of the pin. Instead of continuing both
faces of these bars to the same depth I recess the bar which does not
resist the oscillating bar so that a short distance from the upper side of
the pin box the slot becomes very wide, and that facilitates the escape
of dirt or "fluke" which finds its way into these slots.
