Improvements in Taking up Motions for Looms.
We THE OLDHAM VELVET MANUFACTURING COMPANY LIMITED of the
Falcon Mills, Oldham, in the County of Lancaster, and BENJAMIN MARSHALL
in the employment of the said Company do hereby declare the nature of this
invention to be as follows :-
Our said invention relates to means or apparatus for taking up the woven fabrics
in looms and especially to the taking up of pile fabrics. The apparatus is con-
structed as follows. We mount a ratchet wheel upon a spindle having its bearings
in a bracket secured to or extending from the frame of the loom, and pivot in
connection therewith an arm or pawl carrier arranged to be operated at each pick,
by the slay or other suitable moving part of the loom. A pawl on the said pivotted
arm engages with the teeth of the ratchet wheel so that the wheel is rotated to the
extent of say one tooth at each pick. The spindle upon which this ratchet wheel
is mounted also carries a toothed pinion which gears with a spur wheel on the
inner end of a spindle carried in bearings on the frame, the outer end of the said
spindle carrying a worm which gears with a worm wheel on an upright shaft.
The upper end of the said upright shaft carries a bevel wheel gearing with another
bevel wheel fixed on the outer end of the shaft of the taking up roller. The said
taking up roller is mounted beneath or in juxtaposition to the breast beam of the
loom and is covered with spikes or card teeth which engage with the woven fabric
and draw it forward over the breast beam. As the fabric is drawn forward by the
taking up roller it is rolled upon a beam in front of the loom and the said beam is
actuated in the ordinary or in any suitable manner so as to coil on the fabric as it
is advanced at each pick by the taking up roller, provision being made to decrease
the speed of the coiling on roller as the diameter of the coiled on fabric increases.
The apparatus is constructed or adjusted so as to give the proper speed to the
taking up roller and provision is made for the introduction of change wheels in the
train of gearing so as to vary the speed of take up. The range of changes available
by this gearing is very wide and can be adapted to open as well as close fabrics.
The taking up being constant the fabric and warp are maintained at an equable
tension, and the defects of unevenly woven cloth arising from undue straining or
undue slackness are avoided. We do not confine ourselves to the exact disposition
of parts in the taking up apparatus as these might in some respects be varied.

Improvements in Taking up Motions for Looms.
We THE OLDHAM VELVET MANUFACTURING COMPANY LIMITED of the
Falcon Mills, Oldham, in the County of Lancaster, and BENJAMIN MARSHALL
in the employment of the said Company, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
drawings:-
Our said invention relates to means and apparatus for taking up or drawing
forward the woven fabrics in looms and especially to the taking up of pile fabrics.
For this purpose we employ a ratchet wheel actuated by a pawl carried by a lever

page_text: which is connected with one of the slay swords or with an arm upon the slay
shaft and we connect the said ratchet wheel by means of spur and worm gearing
with the taking up roller shaft parts-of-the said gearing being changeable in order
that the extent to which the fabric is drawn forward after each pick may be capable
of variation.
Our invention will be most clearly understood when described with reference
to the accompanying drawings wherein is represented so much of an ordinary loom
as we consider necessary to the proper illustration of our invention.
Of these drawings Fig. 1 represents a partial front elevation and Fig. 2 a partial
end elevation of a loom fitted with our improved motion.
In the said figs. a represents the ordinary "taking up" roller
the cloth
beam the slay and d the slay shaft to which are attached the two slay swords
which carry the laith. One of these slay swords is represented at e. To the end
frame of the loom is bolted or secured a bracket which carries a shaft g and this
shaft is provided at one end with a ratchet wheel and at the other end with a
pinion which gears with a spur wheel i.
The wheel is secured upon one end of a shaft ; which is mounted in a second
bracket which is fixed to the framing. Upon the other end of the shaft is fixed
or formed a worm which gears with a worm wheel m which is fixed upon the
lower end of a vertical shaft n which is mounted to revolve in bearings in
brackets oo which are secured to the framing. The upper end of the shaft n
is connected by means of a pair of bevel spur wheels pp with the shaft of the
taking up roller a.

A pawl levery is loosely mounted upon the shaft and carries a pawl g' which
engages with the teeth of the ratchet wheel. The free end of the lever
connected by means of a link with the end of an arm s which is secured upon the
slay shaft d the result being that as the said shaft rocks during the beating up of
the weft the lever q is also caused to rock upon the shaft g and the pawl is thereby
made to turn the ratchet wheel intermittently in the direction indicated by the
arrow the wheel being turned to the extent of one two or more teeth at each
"beat up
or to and fro vibration of the slay according to the proportions and
adjustment of the parts. An arm of the bracket carries a detent t which
prevents backward movement of the ratchet wheel h.
"
The motion of the ratchet wheel is communicated at a reduced ratio to the
taking up roller by the gearing hilm and p as will be readily understood. The
taking up roller is covered with roughened sheet metal or with cards or is
otherwise roughened by any ordinary or suitable means so that it will be capable
of drawing forward the fabric which is wound upon the cloth beam bin the ordinary
manner. The bracket is secured to the framing by means of a bolt f2 which
passes through a slot in the bracket so that the latter can be adjusted vertically so
as to vary the distance between the shafts g and when it is desirable to change
the gearing. By varying the proportions of the two wheels or wheel and pinion hi
a wide range of regulation of the fineness of the weaving can be obtained and this
range can be further extended by the varying the stroke of the lever y so as to
cause it to take only one tooth or two or more as aforesaid. To facilitate this
variation of the stroke of the said lever the connection of the link with the arm s
or with the said lever may be arranged to be adjustable nearer to or further from
the centre of the shaft dorg as the case may be. An arm u is hinged to one end
of the upper end f₁ of the bracket f and has its other end connected by a link u
with a lever arm which projects from a shaft or rod which extends to the other
end of the loom or to a part where it can be conveniently acted upon by the stop
rod. When the stop rod is moved to stop the loom the arm u is lifted and acting
upon a pin or projecting part of the pawl q' raises the pawl out of gear with the
ratchet wheel.

So long as the loom is standing the ratchet wheel can be turned backwards or
forwards to any desired extent by applying a suitable handle upon the squared end
of the shaft g or if preferred the lever q might be applied at the back of the ratchet

page_text: wheel and a handle be fixed or formed upon the front of the wheel. The link r
might in some cases be connected with the slay sworl and the arms be dispensed
with. The taking up being positive and uniform in degree the fabric and warp are
maintained at an equable tension, and the defects of unevenly woven cloth arising
from undue straining or undue slackness are avoided. Also the wide range of
regulation of the rate of taking up enables us to use the same looms for weaving
close woven pile fabrics or very light and open goods as may be desirable.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The combination of parts for imparting positive taking up motion to the
roller a in a loom for weaving as set forth and indicated.
2. A taking up motion for a loom consisting of a ratchet wheel actuated by a
pawl operated by the slay shaft of a loom such wheel being connected by change
and worm and wheel gearing and by bevel gearing or suitable gearing with the
taking up roller substantially as and for the purpose set forth.
3. The ratchet wheel the change gearing the worm and wheel the shaft n the
gearing p and the pawl q' carried by a vibrating arm actuated by a part fixed
upon the shaft d substantially as and for the purpose set forth and indicated.
