Improvements relating to Presser Flyers.
I, JOHN NEWTON of 39 Albert Road, Farnworth near Bolton in the County of
Lancaster, Grocer, do hereby declare the nature of my said 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 refers to improvements relating to presser flyers for machinery
known as slubbing, intermediate, roving, and other similar machines employed in
the process of preparing cotton and other fibrous materials and consists in providing
ready and efficient means for fixing and removing pressers instantaneously by which
soldering aud brazing will be dispensed with. It is well known that the old or
present method of mounting pressers on flyers is by means of bearings or lumps
soldered or brazed to the flyer legs. My invention is designed to dispense with this
system, which I effect by means of a grooved spring catch secured in any convenient
manner to the flyer leg. The presser arm is constructed to move in the groove in
the said spring catch, by which it is held in position vertically. The clip of the
presser is provided with stops or projections to determine the movement of the
presser radially. The opposite end of the presser leg is provided with a bearing
which slides and swivels on the flyer leg. When it is desired to fix or remove a
presser from a flyer it is effected by pressing the spring catch back sufficiently to
allow the presser to slide off or on the flyer leg.
Fig. 1 is a front elevation of a presser flyer with my improvements applied.
Fig. 2 is an end elevation of same.
Fig. 3 is an enlarged part sectional elevation of the lower end of hollow leg of a
presser flyer showing my improved grooved spring catch.
Fig. 4 is a sectional plan through line A¹ B'.
Fig. 5 is a sectional plan through line C¹ D', and
Fig. 6 is a sectional plan through line G' H' in Fig. 3.
A is the presser flyer employed in machinery of the description before mentioned
provided with the hollow leg B, on which the presser C is mounted. On the hollow
flyer leg B is secured the spring catch D provided with the grooved end E in which
the circular part G of the presser arm C operates. The circular part G is con-
structed to move in the grooved end E of the spring catch D. The circular part G
clips the hollow flyer leg B, and is provided with the stops or projections H to
determine the movements of the presser radially. The spring catch D is constructed
with the projection I which fits into a slot or opening in the flyer leg, and is provided
for the purpose of preventing or minimising the risk of breaking or straining the
same off sideways when opening the spring catch D to admit or remove the
presser C. The upper end of the presser leg is provided with the bearing or twisted
end J, which will slide and swivel on the flyer leg B. When it is desired to fix or
remove the presser C on the flyer leg B it is effected by simply pressing the lower
or grooved end of the spring catch D back sufficiently to allow of the distance
between the point K and the outside of the flyer leg B being increased beyond the
thickness of the circular part G, which will allow of the same being slid instan-
taneously on or off the flyer leg, thereby entirely dispensing with the old method of
securing bearings or lumps on the flyer leg by means of soldering or brazing each
time it is necessary to remove an old presser or replace a new one.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In combination with a presser flyer the use of a grooved spring catch for the
purpose specified.
2. In combination with a presser flyer the use of a grooved spring catch with a
projection fitting into a slot in flyer leg for the purpose specified.
