I, JOHN BULLOUGH, of the Firm of Howard and Bullough, of
Accrington, in the County of Lancaster, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN WARPING OR BEAMING MACHINES,"
to be as follows:-
My Invention consists in a certain mechanical arrangement whereby
a warper is relieved from the necessity of turning the yarn beam by
hand to take up the slack or overrun of the bobbins before starting the
machine after a stoppage.
This arrangement may be described as follows:-At the end of the
warp drum shaft I have a friction motion or clutch box which is brought
into gear by the pressure of the warper's foot on a treddle running along
the front of the cylinder and near to the floor; this treddle is held
by two arms, one at each side of the drum, which are fastened to a rod,

page_text: each end of which rests in a bearing fixed to each side of the machine.
The machine having stopped the swing or drop rollers descend and take
up the overrun of the bobbins. Before the machine can be safely
started again at its proper speed these rollers must be wound slowly up
and the machine be kept on at a slow speed till the bobbins have got in
motion, otherwise the too sudden starting of them would break the
threads. To guard against this evil the warper has heretofore generally
turned the machine by hand till it was safe to let it go at full speed; or
if, in order to avoid the labour, she has tried to wind the rollers up
slowly by putting only a narrow portion of the driving strap on the
fast pulley it has been at the risk of the evil mentioned above. In my
plan the warper can wind the rollers up and set the machine in motion
at any speed she desires by simply pressing her foot with greater or less
force on the treddle, causing the friction plates to be brought more or
less firmly together, and of course to drive with more or less spced. I
also cause the guide slots in which the ends of the drop rollers work to
be continued upwards to as high a point as may be necessary to prevent
the rollers being checked suddenly even if they are being wound up with
careless speed.
The second part of my Invention consists in a modification of the
reversing motion. Instead of having two catches and two catch wheels
with the teeth set in opposite ways I employ only one catch and one
catch wheel of a coarso pitch, the teeth of which are straight on both
sides alike.
The next part of my Invention is for the purpose of preventing
"fluke," "fly," or "floss" getting into the slots in which the pins or
fallers work and should work freely. With this object I have a brush or
a row of bristles long enough to reach from the expanding comb to which
the clip which holds them is attached across the pin frame. This row of
bristles standing out horizontally from the expanding comb and along its
entire length, and lying over the slots in which the pins are placed, receive
any fibres that fall from the threads running above them; the surface
of the pin frame itself and the slots in which the pins work are thus
protected from the shower of fibres by the bristles, which spread them-
selves like a network over them. The fibres that fall are prevented from
accumulating to an inconvenient extent on the bristles in the same
manner as they are prevented now from accumulating on the pin frame,

page_text: that is by the threads being forced down to the surface of the frame
every time the machine stops, the fibres attaching themselves to the
threads which carry them away when they get in motion. I also form
the reed hook with a blade to cut lappers off the plush roller.
