COMPLETE SPECIFICATION.
Improvements in Apparatus for Driving and Adjusting the Rotation
of the Top Squeezing Rollers of Yarn Sizing Machines.
I JOHN TATTERSALL formerly of 310 Hyndburn Terrace Accrington in the County
of Lancaster, Machinery Agent, at present residing at Enschede, Holland, 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:-
This invention relates to an improved method of, and means employed in driving
the top squeezing roller, or rollers of slasher sizing machines, and tape sizing, and
dressing machines, by means of which the top squeezing roller is driven so as to
avoid slipping, thus obtaining steadier, and more regular working of the same, and
with better results than heretofore when the top squeezing roller has been driven
by frictional contact, and the speed at which the said roller is driven, can easily, and
readily be regulated as required, and being driven from both ends there is no liability
of the roller "lifting" or shaking, and thereby allowing too much size to pass forward
with the yarn, whilst running and thus the warp threads, or yarns are prevented
from being unequally sized, and the top squeezing roller is always ready for work,
whether more, or less flannel is used for covering such roller, and consequently
making the diameter greater, or smaller, and will work equally well, and regularly
with light, or heavy sizing, or with thick, or thin size, and the invention can readily
be fixed to new, or old existing machines.
Such being the nature, and object of the said invention, the following is a complete
description of same, reference being had to the accompanying drawings forming a
part of this specification in which :-
:-
Fig. 1. is a side elevation of so much of a sizing machine as is required to clearly
illustrate my invention.
Fig. 2. is a plan view of Fig. 1.
Fig. 3. is a side elevation of my improved driving apparatus together with belt,
rope, or chain tightening device.
Fig. 4. is an end elevation of driving apparatus and rope, or chain tightener.
Fig. 5. is a plan view of Fig. 3.
Fig. 6. is a detail, drawn to enlarged scale, of the friction device.
According to this my said invention I employ a shaft 1, parallel to, and preferably
behind the sow box 2, and on each end of the said shaft 1 is a pulley 3, and on each
end of the squeezing roller 4 is a pulley 5, and over these pulleys 3. 5 I pass a belt,
rope, or chain 6 (as may be preferred) so that motion is communicated by the belt,
or chain 6 from the pulleys 3. 3. on the shaft 1, to the pulleys 5. 5 on the axis of the
squeezing roller 4.
In lieu of the belt or chain 6 it will be obvious, that by a train of gear wheels the
requisite motion can be imparted to the top squeezing roller 4 from the shaft 1.
For driving the first mentioned shaft 1 I fix thereon a bevel wheel 7 gearing with
a bevel wheel 8 having a friction device 9 (see Fig. 6.) on the side shaft 10 of the
sizing machine-such side shaft 10 being driven in the ordinary, and well
known way.
In combination with the driving belt, chain, or rope 6 a tightening device such
as 11 (see Fios 3 4 and 5) may ha amplaread fan tabia
"all"

page_text: - Having now particularly described and ascertained the nature, and object of the
said invention, and in what manner the same is to be performed, I declare that
what I claim is :-
The improved apparatus for driving the top squeezing roller, or rollers of machines
for purpose aforesaid, wherein is employed a driving belt, rope, or chain, or a train
of gear wheels, together with, and controlled by a friction device, such as illustrated,
and all in. combination, and for purpose herein fully described.
Dated this 22nd day of May 1890.
