IMPROVEMENTS IN BOILING SIZE UNDER STEAM PRESSURE
Year: 1885

page_text: ALFRED HITCHON Machine Fitter Globe Iron Works Accrington, in the County
of Lancaster, that I do hereby declare the nature of my invention for IMPROVEMENTS
IN BOILING SIZE UNDER STEAM PRESSURE, to be as follows:-
The purposes of this Invention is to maintain size being boiled under a constant
steam pressure, also to be automatic in action by discharging through a safty valve
the boiling size at about the same rate as the incoming cooler size which is under a
separate mechanical control, the former being operated by internal pressure-the
latter by a floating hollow ball or roller being connected by levers thereto. This
invention may be applied to the covered-in box of the ordinary construction made
along in close contact with the main size box that forms part of a sizing machine
into which the yarn is immersed if provided with a properly secured lid to with-
stand the internal steain pressure in the boiling box part-the weighted blow off
safety valve for size entering to the main size box will be the new application I add
to, for increasing the small pressure hitherto 'caused by the steam only having over
a divided partition or other equivalent distance to travel before it leaves the liquid
size for the open atmosphere. When the boiling size box has to be an addition
I prefer a similar shape of box to that shown by James Kenyon in his patent
granted AD. 1867, No. 3627. also a similar kind of float roller for actuating the
regulation of the inlet of the size into the boiling size box. But with a new kind
of valve for which a provisional specification was lodged by me on the 17th day of
September this present year and numbered 11008. By this present Invention I do
not couple the inlet float valve and the outlet discharge valve together by any
kind of rod or lever for the purpose of working them simultaneously-as they each
will receive their action from a different source of power, viz:-the discharge valve
from within the boiling box, and the inlet valve from the size box to which the
discharge valve will have to deliver and fill the size box to a proper level before it
causes the float valve to shut off the supply. I also provide means for the blow off
discharge valve, operating on the reducing or steam inlet valve for giving a larger
quantity of steam when more size is being used, or for the same like purpose of
shutting off the steam when none or little size is being allowed to pass the inlet
size valve to the boiling box. I also make use of an angle way plug tap in a four
way shell for the convenience of turning the size in different directions.

I ALFRED HITCHON of Globe Works, Accrington in the County of Lancaster
Machine Fitter do hereby declare the nature of my invention for IMPROVEMENTS
IN BOILING SIZE UNDER STEAM PRESSURE and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The purposes of this Invention is to maintain size being boiled under a constant
steam pressure, also to be automatic in action by discharging through a safety
valve the boiling size at about the same rate as the incoming cooler size which is
under a separate mechanical control, the former being operated by internal pressure,
the latter by a floating hollow ball or roller being connected by levers thereto.
Such being the nature and object of this my 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 shewn an oblique view of size boiling box its connections with size box
of the Sizing Machine.
Fig. 2. is a plan view of size boiling box and its connections drawn to larger
scale.
Fig. 3. is side elevation of the feet valve,
Fig. 4. is an end view of the said valve.
The size to be boiled is forced by use of the ordinary pump through the pipe 1.
and through the valve 2. pipe 3. to the lower part of the size boiling box 4.
At 5 is a steam pipe having loaded valve 6, through which, and through the
pipe 7., and steam tap 8., the steam passes to the lower part of the box 4.
At 9 is a discharge pipe connected to the higher part of the box 4, and having a
discharge valve 10., from which extends the pipe 11., into the size box 12-At 13 is
a "float" roller connected by link 14 to the lever 15 supported on bracket stud or
pin 16 and having at its other end a pendant arm 17 and connected with the
lever 18 of the spindle of the valve 2.
The action is as follows:-The reducing valve 6., having its weight adjusted and
the tap 8. being opened, steam passes to the boiling pan 4, until the pressure within
the pan exceeds the weight upon the discharge valve 10., whereon the latter is opened
and surplus steam as also that part of the size on and nearest the surface is by way
of the pipe 11. discharged into the size box 12.-The inlet of cold size to the
boiling box being controlled through the action of the float roller 13. parts 14, 15,
16, 17, 18 as is well understood; the motion of the lever 18 when opening the
valve 2 for the admission of further supply of size to boiling box 4-a projecting
adjustible finger 20 on the cross shaft of inlet valve 2 is arranged to come in
contact with pendant projection 19 from lever of steam reducing valve 6 for the
purpose of lifting the lever of the latter at intervals, by the action of the float
thereby preventing the liability, the reducing valve getting fast or not performing 4
the work for which it is intended when in order.
The inlet flote valve for size boiling box as shown in detail side elevation Fig. 3
and end view Fig. 4 consists of spindle and mushroom head 19-20.

page_text: The upper part 21 on slacking the set screw 22 may be turned on the joint 23 so
as to admit of the lever 18 being brought into position for connecting with part 17
of Fig. 1., the spindle 24 is provided with an eccentric 25., against which head of
spindle 19 bears, so that back pressure on the valve 20. produces comparatively
little effect on the float 13.
At 26 (see Fig. 2) is a four way tap for diverting and turning the flow of size.
When open in the direction of the size will pass to the box 12, a quarter
turn would close that outlet and discharge would be to the boiling pan 4., a further
quarter turn would then cause discharge at the pipe 27. for drawing off size for
inspection.
Having thus described the nature and particulars of this my said invention and
in what manner the same is to be performed, I declare that what I claim is:-
1. The general construction arrangement and combination of parts of the
improved apparatus for purpose and as herein fully described and illustrated by
the drawings annexed.
2. The loaded valve 10. for discharge of Steam and Size--Size Box 4. Pipe 11
and Size Box 12. all in combination and for purpose herein fully described.
3. The float inlet size valve 2 constructed as illustrated by Figs. 3 and 4 as and
for purpose herein fully described.
4. The angle plug tap in a four way shell for purpose of diverting and turning
the Size in different directions in combination with a Size boiling box such as 4. and
for purpose fully described herein,
