We, SPENCER CRIGHTON, Managing Director of the Firm of Crighton & Sons,
Ltd., Moscow Machine Works, Church, Accrington, in the County of Lancaster,
and JOHN THOMAS HAWORTH, of No. 1, Swiss Street, Accrington, aforesaid,
Manager with the said firm, do hereby declare the nature of this invention to be
as follows:
Our said invention has reference to improvements in or connected with yarn
sizing and beaming machines.
In sizing machines the sized yarn is wound upon the beam under the pressure
of presser rollers which are gradually lowered as the beam fills as is well under-
stood.
Under one part of our invention we provide means whereby the presser carrier
is capable of a wide range of movement to accomodate the presser rollers to the
varying diameter of the beam from the empty to the fully wound stage.
To effect this we actuate the presser carrier by means of pivotted levers, or
system of levers, which when extended are capable of raising the carrier to
any required height and which will collapse to permit the carrier to be lowered
to its fullest extent when the beam is completely wound.
A convenient method of effecting this is to provide each end of the presser
carrier with toggle links which when extended raise the carrier to the required
height.

We do not confine ourselves to this however as the arrangement of levers may
bo varied in many ways by an experienced mechanic. For instance each end of
the presser carrier may be provided with a system of hinged levers or links on
the lazy tongs" principle which would serve effectually to raise the carrier from
a low position to any required height. Or single levers pivotted to fixings
disposed at each end of the carrier might bear centrally upon the carrier to raise
it. To provide for the presser carrier preserving a truly vertical path we arrange
a suitable guide rod or rods engaging with ways or grooves in the carrier and an
anti-friction bowl or bowls may be employed to reduce the friction between the
guide rod and carrier.
The presser carrier is actuated in the usual manner by means of a finger or pro-
jection carried on a square shaft the end of the shaft being provided with the
usual lever and counterbalance weight.
We further provide means whereby the regulating of the pressure of the presser
rollers upon the yarn is readily under the control of the attendant so that the
pressure may be adjusted without stooping to the square shaft as is necessary
under the present practice.

page_text: To effect this we provide the square shaft with a friction drum or pulley
embraced by a hinged or flexible strap of metal or other material. The metal
strap may be lined with felt, leather or other suitable material to afford frictional
resistance to the pulley. We arrange to expand and contract this brake strap
by means of a vertical screwed shaft engaging with a nut carried by or formed
on the brake strap, and revolve the shaft by a hand wheel or handle so that any
desired pressure of the presser rollers may be brought to bear upon the yarn,
such pressure being more readily ascertained by the attendant, who may test the
pressure with one hand whilst operating the tension device with the other. We
do not confine the use of the vertical shaft and hand wheel or handle to the brake
pulley as described, as the shaft and hand wheel, or equivalent means such as a
line of gearing, could be readily adapted to existing tension devices so as to
obviate the necessity for the attendant stooping to the low level of the square
shaft.
In order to prevent the ends of the presser rollers from coming into frictional
contact with the beam flanges we provide each roller with a sliding bar carrying
an adjustable stop which comes into contact with a screwed stud. The screwed
stud provides an adjustable means to limit the longitudinal traverse of the bar
and connected roller so that the presser rollers may be readily arranged to just
clear the beam flanges. Further, by means of these limiting stops the presser
rollers are maintained in due relation to tho yarn on the beam even when the
same is wound to a diameter in excess of the diameter of the beam flanges.
We might provide the sliding bars with a clip which could be tightened at the
required time by a screw or the like so as to grip and prevent the further
traverse of the sliding bars and connected presser rollers.
A further part of our invention relates to the method of mounting the bowls in
the presser carrier which support the presser rollers. We may employ parallel
bowls but instead of mounting them in the carrier in bearings which require
to bo adjusted so as to bring the surface of the bowls to bear against the presser
rollers, we make the carrier brackets with bearings which are inclined inwards
and downwards so that the bowls carried therein bear with their entire upper
surfaces upon the presser rollers. By these means the bowls require no adjust-
ment and cannot get out of truth on account of interference by an inexperienced
person. We do not confine ourselves to the exact form of bowl."
Instead of mounting the bowls in inclined bearings as described we may form
the presser rollers taper or slightly conical and arrange the bowls so as to bring
the bearing surface of the presser rollers parallel with the axis of the warp beam
so as to bear equally on the beam.

We, SPENCER CRIGHTON, Managing Director of the Firm of Crighton & Sons,
Ltd., Moseow Machine Works, Church, Accrington, in the County of Lancaster,
and Joix THOMAS HAWORTH, of No. 1, Swiss Street, Accrington, aforesaid,
Manager with the said firm, do hereby declare the nature of this invention and

page_text: in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement and accompanying drawings:-
-
Our said invention has reference to improvements in or connected with yarn
sizing and beaming machines.
The accompanying sheet of drawing to which we will refer clearly illustrates
our invention.
Fig. 1, shows in elevation our improved method of actuating the presser carrier.
Fig. 2, is an end view thereof.
Fig. 3, is a modification.
Fig. 4, shows our improved means for operating the friction or braking device
of the presser rollers.
Figs. 5 and 6 show the means we have devised for preventing the ends of the
presser rollers from coming into frictional contact with the yarn beam flanges.
Fig. 7 illustrates our improved method of mounting the bowls on the presser
carrier.
In sizing machines the sized yarn is wound upon the beam under the pressure
of presser rollers which are gradually lowered as the beam fills as is well under-
stood.
Under one part of our invention, illustrated in Figs. 1 to 3, we provide means
whereby the presser carrier is capable of a wide range of movement to accom-
modate the presser rollers to the varying diameter of the beam from the empty
to the fully wound stage.
To effect this we actuate the presser carrier by means of pivotted levers, or
system of levers, which, when extended, are capable of raising the carrier to
any required height and which will collapse to permit the carrier to be lowered
to its fullest extent when the beam is completely wound.
A convenient method of effecting this is to provide each end of the presser
carrier a with toggle links 6 which when extended raise the carrier to the required
height.
In the drawings the toggle links are shown collapsed.
We do not confine ourselves to this however as the arrangement of levers may
be varied in many ways by an experienced mechanic. For instance each end of
the presser carrier a may be provided with a system of hinged levers or links b
on the "lazy tongs" principle which would serve effectually to raise the carrier
from a low position to any required height as shown in Fig. 3.
Or single levers pivotted to fixings disposed at each end of the carrier might
bear centrally upon the carrier to raise it. To provide for the presser carrier
preserving a truly vertical path we arrange a suitable guide rod c or rods,
engaging with ways or grooves in the carrier and an anti-friction bowl d or bowls
may be employed to reduce the friction between the guide and carrier as shown in
Fig. 2.
The presser carrier is actuated in the usual manner by means of a finger or
projection e carried on a square shaft the end of the shaft being provided with
the usual lever g and counterbalance weight h.
We further provide means whereby the regulating of the pressure of the presser
rollers upon the yarn is readily under the control of the attendant so that the
pressure may be adjusted without stooping to the low level of the square shaft
as is necessary under the present practice.
To effect this we provide the square shaft f with a friction drum or pulley i
embraced by a flexible strap j of metal or other material as shown in Fig. 4.
The metal strap j may be lined with felt, leather or other suitable material to
afford frictional resistance to the pulley. We arrange to expand and contract this
brake strap by means of a vertical screwed shaft & operated by means of a hand
wheel by revolving which the screwed spindle & can be raised or lowered. The
screwed spindle is connected at the lower end to a lever m mounted at m¹ upon
a fixed stud. The lever m carries pivotted fingers ma to which the brake strap ; is
connected. By revolving the hand wheel and turning the lever m upon its

page_text: pivot the brake strap can be tightened upon the pulley i so that any desired
pressure of the presser rollers may be brought to bear upon the yarn (shown in
dotted lines in Fig. 2) such pressure being more readily ascertained by the
attendant, who may test the pressure with one hand whilst operating the tension
device with the other. We do not confine the use of the vertical shaft and hand
wheel or handle to the brake pulley as described, as the shaft and hand wheel, or
equivalent means such as a line of gearing, could be readily adapted to any
existing tension devices so as to obviate the necessity for the attendant stooping
to the low level of the square shaft f.
In order to prevent the ends of the presser rollers n from coming into frictional
contact with the yarn beam flanges we provide each roller with a sliding bar p
secured to the roller by means of a bracket p².
The sliding bars p are provided with a clip 7 shown more clearly in the enlarged
views Figs. 5 and 6. One of the sliding bars p, shown in the right hand of the
cross sectional view Fig. 6, is secured to the clip q by means of a set screw r.
The clip therefore slides with this bar.
The other bar slides loosely in the clip q, sufficient clearance being provided to
permit this. On the presser rollers n reaching the warp beam flanges the screws
is operated to bind the loose bar to the clip q so that the two pressor rollers n
are thus locked together. This clip locking motion may be brought into
action just before the presser rollers bear against the beam flanges or when they
havo come into frictional contact therewith.
In the latter case the clip tends to bend the sliding bars pinwards shortening
their length to a fractional degree and withdrawing the presser rollers a hairs-
breadth away from the beam flanges.
A further advantage from the use of the clip locking means arises in the fact
that the clip locking means retain the presser rollers in due relation to the yarn
on the beam even when the same is wound to a diameter in excess of the diameter
of the beam flanges.
A further part of our invention relates to the method of mounting the bowls
in the presser carrier which support the presser rollers. We employ parallel
bowls but instead of mounting them in the carrier « in bearings which require
to be adjusted so as to bring the surface of the bowl & to bear against the presser
rollers, we make the carrier brackets & with fixed bearings which are inclined
inwards and downwards so that the bowls carried therein bear with their entire
upper surfaces upon the presser rollers. Fig. 1 shows the bowls & with their
bearings inclined downwards. A separate plan view of one of the bearing
brackets is shown in Fig. 7 from which it will be seen that the bearings for each
side bowl are also inclined inwards.
This method does not apply to the central bowl but to the outside bowls only.
By these means the bowls t require no adjustment and cannot get out of truth
on account of interference by an inexperienced person.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1). In yarn sizing machines, mounting the presser carrier upon pivotted levers
or systems of levers, capable when extended of raising the carrier to any required
height and collapsible to permit the carrier to be lowered to the fullest extent
substantially as described.
2). In yarn sizing machines elevating the operating means for the friction or
braking device used for regulating the pressure of the presser rollers, so as to
avoid the necessity of stooping to the low level of the square shaft when adjusting
the pressure substantially as described and illustrated.
3). In combination with the presser rollers of yarn sizing machines, a clip used
in conjunction with sliding bars to limit the longitudinal traverse of the presser
rollers and sliding bars, so that the rollers are prevented from coming into, or may

page_text: be removed from, frictional contact with the warp beam flanges substantially as
described and shown.
4) Mounting the bowls of the presser carrier in fixed bearings inclined inwards
and downwards in the manner for the purposes and substantially as described and
shown.
5) The general arrangement construction and combination of parts comprising
the improvements in and relating to yarn sizing machines substantially as
