THOMAS SINGLETON of Over Darwen in the county of Lancaster Machine
Maker "IMPROVEMENTS IN LOOMS FOR WEAVING
"
My Invention relates firstly to an improved arrangement for regulating the
tension on the beam around each ruffle of the back beam I pass a chain or rope,
one end of which after passing downwards and around a runner or pulley is
secured to a dead bracket on the loom side and the chain is regulated by a screw
the other end of the rope passes downwards and on to a weighted lever, a sliding
link embraces the two chains of ropes, and by moving this link nearer to or further
from the ruffle it regulates the tension of the rope or chain upon the beam and also
the amount of oscillation of the. beam, also by moving the weight towards the
fulcrum of the lever the oscillation of the beam is increased. as the yarn on the
beam diminishes.
Or I employ a rope or chain which after passing around the ruffle of the beam
one end is secured to a hook passing through a dead stop stud or bracket the hook
is screwed so as to be adjustable the other end of the rope is attached to a
pivotted weight lever a sliding link embraces the two chains as before described
The regulating screw is used only at the beginning of the warp for regulating
the chain.
A feeler can be used to the above arrangement for self actingly regulating the
weight.
If required instead one end of each chain being secured to the dead stop after
passing around their respective pulleys they may each be carried over and
forwards and joined towards the centre of the loom thus making one endless chain,
pulling against each other as if from a fast end as before.
Secondly to an improved arrangement of feeler for self actingly regulating the
weight upon the back beam so that the weight may slide down the lever and take
off the weight at any required speed, I employ a feeler in a slide, to the feeler is
attached a chain which passes alternately under runners upon a lever and over
runners or studs upon a fixed bracket above such lever, by this means as the feeler
arm rises it raises the lever. and so allows the weight to travel any required
distance according to the length of the lever, and the number of studs or pulleys.
Thirdly. To an improved wing rod, I strengthen the wing rod either in the
centro or at two divided positions by increasing its size or substance and attach it

page_text: to the sley by means of two clip brackets the thickened part being partly embeddled
in the aley bottom if required additional strength is added to the duck bill bracket
or brackets one or two duck bills may be used as preferred as by this means the
tension or strain upon the rod is not transmitted to its whole length, the wing rod
may be made of either wrought iron, malleable iron or steel as suitable, or the wing
rods may be made of Kirkshall Forge Co rolled iron all except the thickened parts
in the centre or divided position which is rolled iron
Fourthly To an improved strap fork joint I fix to the strap fork arm a long
bearing pin or stud preferably on its underside a corresponding long bush into
which the stud fits is carried in the bracket, this bush is threaded on its outside.
and attached to the bracket by nuts one on each side so that the height of the
strap fork arm can be regulated to any nicety a large bearing surface is by this
means obtained and thereby great durability or I lengthen the stud of ordinary
strap fork joint and on the projecting part of the stud I place a taper bush attached
by set screws so that when either the stud or the bush of tho strap fork wears, the
taper bush can be lowered to fill up the space and prevent a shaky joint, or the
strap fork may have a conical hole in the bush the bush being on the underside
and a corresponding conical stud and nut or bolt cast in it to secure it to the
bracket in this case there is no tendency to bite or lock.
Fifthly. My improved swell consists of a steel spring constructed so that both
ends are fast or slotted and the bowed portion presents itself to the shuttle.
Sixthly. To an improved construction of brake lever and shoe bracket or brake
block.
I construct my brake lever so as to work or pivot on a stud bracket and also to
carry a swivelling or pivotted shoe bracket the stud and bracket are cast in one
piece the bearings or bosses which embrace both stud brackets are in halves like a
pedestal and are held together by a bolt or screw so that no boring or turning is
required for either the pivots or bearings, the shoe being pivotted beds or regulates
itself to the surface of the wheel by this means the putting on and taking off of
the brake is guaranteed.
The studs above the brackets may either be cast with a shoulder or head on or
may be in the form of plain pins and fingers are cast on one lialf of the bearing
bracket so as to keep the brackets in position.
Seventhly. To an improved pinion wheel stud for the taking up motion.
I construct my stud of Kirkstall forge iron, and drive it in to a suitable hole in its
bracket and secure it by a pin and so dispence with the turning and rivetting, the
tumbler for keeping the wheel in position. I construct of wire looped and pivotting
on two paps or nipples cast on the bracket or instead of wire it may be of malleable
iron and nipped into position or may be of cast iron and in two parts, held together
by a bolt.
Eighthly. To an improved stud for the taking up wheel I construct my stud of
Kirkstall iron one uniform thickness a pin is put in for the pinion to key upon
and a boss and set screw for steadying it in position by this means no turning or
turning down and screwing is required as well as a nut being dispensed with.
Ninthly. To an improved spindle stud. I construct my spindle stud in two
pieces packed between with leather pasteboard or suitable substance so that the
shuttle when striking against it is not injured or the spindle stud may be made in
two pieces without any intermediate packing the spindle cut being carried by one
piece when worn this part only requires renewing.
To dispense. with the eye bolt I construct the spindle stud with a slot and a
loose pin to carry the spindle any ordinary bolt can thus be used for securing same
