IMPROVEMENTS IN MACHINERY EMPLOYED FOR SIZING - YARN.

This invention relates to the friction motion of the class known as lever 'friction
motions and the object is to reduce the loss of power occasioned by contact of boss
or exterior of the apparatus on and against a stationary part of the machine.
According to one construction of this my invention. I employ between each pair
of friction plates a thin plate or disc of metal faced with flannel, cloth or other like
substance and keyed on the shaft which drives the weavers beam the inner and
outer friction plates engage with each other after the manner of an ordinary clutch
and thereby become as one. As the friction plates are driven they by acting-on
the flannel washers cause the latter to drive the metal plates or discs within them
and the latter as described being keyed upon the shaft gives the variable required
motion.
The frictional apparatus aforesaid is acted upon by lever and weight arrange-
ments such or similar to that in the specification of Letters Patent granted to
William Snowcroft Lowe dated 7th May 1870 No 1308.
Another construction of frictional apparatus comprises similar arrangement to
the one described above but the outer friction plates are acted upon, by, Jevers the
fulcrum of the said levers being formed by one of the outer plates the ends of the
levers acting upon the other plate the inner ends of the said levers being connected
with a loose boss on the boss of one of the frictional, plates, the plates levers and
boss revolve together thereby driving the central flannel faced disc: as before
described A similar arrangement of levers to Lowe's Patent being applied to the
boss against the levers for putting on the variable pressure.

plate A the plate A. levers J and boss P revolve together thereby driving the
central flannel faced disc R as before described-Ei is the toothed wheel or
pulley-A similar arrangement of levers to Lowe's Patent being applied to the
boss against the levers for putting on the variable pressure as already described.
Having thus fully described the nature and particulars of this my said invention
together with the manner in which the same is to be performed I would have it
understood that I do not claim the lever motion herein referred to-What I do
claim is:
Firstly-The construction and combination of parts constituting the improved
frictional apparatus as herein described and illustrated by drawings annexed
Secondly The use of plates such as A. B in combination and connected with
each other (as at F) so as to become as one and move simultaneously for purpose
set forth herein and as illustrated by Drawings annexed hereto
In Witness whereof I the said Alfred Hitchon have hereunto set my hand and
seal this first day of May in the year of Our Lord one thousand eight hundred and
eighty four
