Improvements in Yarn Beaming and Sizing Machines.
We, WILLIAM SWARBRICK, of 9, Russia Street, Accrington, in the County of
Lancaster, Mechanic, and RICHARD GRIMSHAW, of 13, Oswald Street, Church, in the
County aforesaid, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in friction driving gear for beaming and
sizing machines the object being to so construct the friction motion that the machine
will be started gradually and without side strain or end friction or strain on the
drum shaft and also that the machine can be driven with a comparatively small
expenditure of power.
According to this invention we employ a small friction pulley for driving the drop
pin rollers and also a larger friction pulley for driving the machine and both these
pulleys are mounted on the shaft of the wooden drum. Between the large and small
friction pulleys and on the shaft of the wooden drum are two discs or bowls
and between these discs or bowls and slightly above same are two discs or wheels
each being made in two parts with an intervening layer of felt cork or other like soft
material so as to ensure an even grip. The discs, or wheels, are carried in a forked
bracket the lower end of which terminates in a pin carried in a bracket fixed to the
frame end of the machine and the lower end of the pin protrudes beyond the end of
the bracket & rests on the treadle lever of the machine.
The machine is started by depressing the treadle lever as ordinary whereon the
forked bracket and the two discs or wheels fall between and press against the bowls
or discs and the latter against the friction pulleys and the machine is driven. When
the inachine "knocks off," the treadle lever rises and raises the forked bracket and
dises or wheels and breaks the frictional contact and the machine is stopped.
Lock nuts on the shaft of the wooden drum are employed for regulating the
pressure of the friction if required.

We, WILLIAM SWARBRICK, of 9, Russia Street, Accrington, in the County of
Lancaster, Mechanic, and RICHARD GRIMSHAW, of 13, Oswald Street, Church, in the
County aforesaid, Mechanic, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in friction driving gear for beaming and
sizing machines the object being to so construct the friction motion that the machine
will be started gradually and without side strain or end friction or strain on the drum
shaft and also that the machine can be driven with a comparatively small expenditure
of power.
Such being the nature and object of our said invention the following is a complete
description of same reference being had to the annexed drawings in which,
Fig. 1 is a front elevation of the improved friction driving gear applied to a
beaming machine.
Fig. 2 is a plan view of Fig. 1.
According to this invention we employ a small friction pulley 1 for driving the drop
pin rollers 2 and also a longer friction pulley 3 for driving the machine and both these
pulleys are mounted on the shaft 4.of the wooden drum 5. Between the large and
small friction pulleys 1, 3 and on the shaft 4 of the wooden drum 5 are two discs or
bowls 6, 6 and between these discs or bowls 6, 6 and slightly above the same are two
dises or wheels 7, 7 each being preferably made in two parts with an intervening
layer of felt cork or other like soft material 8 so as to ensure an even grip. The discs
or wheels 7, 7 are carried in a forked bracket 9 the lower end of which terminates in
a pin 10 carried in a bracket 11 fixed to the frame ends of the machine and the lower
end of the pin 10 protrudes beyond the end of the bracket 11 and rests on the treadle
lever 12 of the machine.
The machine is started by depressing the treadle lever 12 as ordinary, whereon the
forked bracket 9 and the two discs or wheels 7,7 carried thereby fall between and
press against the bowls or discs 6, 6 and the latter against the friction pulleys 1, 3
and the machine is driven. When the machine "knocks off" the treadle lever 10
rises and raises the forked bracket 9 and discs or wheels 7, 7 and breaks the frictional
contact and the machine is stopped.
Lock nuts 14 on the shaft 4 of the wooden drum 5 are employed for regulating the
pressure of the friction if required.
We are aware that the use of a split disc or wheel in combination with two frictional
pulleys is not, per se, new, and to such we lay no claim, as we have found in practice
that one disc or wheel has a tendency to put lateral strain upon the shaft by bearing
on one side only of the pulleys and dises or bowls.
We are aware of Lancaster's Specification No. 22,135, A.D. 1894, and we do not
claim anything described and claimed therein.
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 general construction arrangement and combination of parts constituting
the improved friction driving gear for beaming and sizing machines, as and for the
purpose herein described and substantially as illustrated by the annexed
drawings.
(2.) In combination with two friction pulleys and two discs or bowls, two split

page_text: wheels or discs mounted in a fork and raised or lowered by the treadle lever as and
for the purpose herein described and substantially as illustrated by the accompanying
drawings.
(3.) The fork bracket 9 terminating in a pin 10 carried in a bracket 11 operating
5 and operated as and for the purpose described.
