Improvements in Parts of Wet Spinning Frames for Flax and other
Vegetable Fibres.
I JAMES PIM STRANGMAN of Sarno in the Province of Salerno, in the
Kingdom of Italy, but at present residing at 1 Kildare Terrace Westbourne
Park in the County of London, Gentleman do hereby declare the nature of this
invention to be as follows:-
This invention relates to the manufacture of the liquid, or water troughs of the
wet spinning frames, of copper, or other suitable metal, or alloy of metals and the
heating of such troughs by means of gas supplied by gas jets applied below
the trough by which means the heating can be regulated with great nicety and
economy and the draw backs attendant on the common plan of employing live steam
for the purpose avoided.
In order, however, to utilize the existing liquid, or water troughs of wet spinning
frames, at present in use, until such time as it became desirable to employ metal
troughs with gas heating arrangements as set forth above. I employ a general
reservoir, or reservoirs of copper, or metal, or alloy of suitable character for water,
or liquid which I heat by means of gas supplied by pipes to jets, or burners below
said reservoir and from this reservoir I conduct the heated liquid to the said
troughs.
Or, the gas may be applied to heat the liquid, or water passing to the troughs of
the spinning frames by means of a coil of piping of metal (copper preferably)
surrounded, or otherwise by the flame whilst the liquid passes through it, or the
liquid heating may be effected in any analogous, or convenient manner adapted to
apply the heat of the ignited gas for that purpose.

Improvements in Parts of Wet Spinning Frames for Flax and other
Vegetable Fibres.
I, JAMES PIM STRANGMAN of Sarno in the Province of Salerno, in the
Kingdom of Italy, but at present residing at 1 Kildare Terrace, Westbourne
Park, in the County of London, Gentleman 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 the liquid or water troughs of the wet spinning frames
and to their construction of copper, aluminium, nickel, or other suitable metal, or
alloy of metals and the heating such troughs and of the water or other liquid usually
contained therein by means of gas jets, or burners, applied below the troughs, or in
other position which may be found suitable, or desirable, so that the temperature
of the water or other liquid contained in these troughs, can be regulated with great
nicety and economy, and the drawbacks attendant on the common plan of employing
live steam for the purpose avoided.
In order however to utilize the existing liquid or water troughs, of the wet
spinning frames at present in use, usually made of wood, until such time as it may
be convenient to substitute therefor metal troughs, with gas heating arrangements
as set forth above I make use of a general reservoir or reservoirs of copper, or

page_text: other metal, or alloys of metals of a suitable character for water or other liquid,
which I heat by means of gas supplied to jets or burners, below said reservoir, or
in other position that may be considered desirable or efficient and I conduct the
heated liquid to the water or liquid troughs of the spinning frame.
Or the gas may be applied to heat the liquid or water passing to the troughs of
the spinning frames by means of a coil of piping of metal (copper preferably)
surrounded or otherwise by the flame whilst the liquid passes through it or the
liquid heating may be effected in any analogous or convenient manner adapted to
apply the heat of the ignited gas for that purpose.
In the process of wet spinning of flax, hemp and other vegetable fibres in certain
cases it is customary to drop upon or cause to be conveyed to or upon by suitable
means, to the retaining, or pressing rollers, or to or upon the drawing rollers, or to
both of these rollers or to or upon one of these aforesaid rollers, a supply of water
or other liquid, this supply of water, or other liquid, is drawn from a pipe, or
reservoir, independently of the liquid, or water, in the water or liquid trough of the
spinning frame or this additional supply of liquid,, may be applied to the rove at or
near the thread plate, by means of a roller as described or set forth in my
Specification of Letters Patent No. 21725 dated December 11th 1891 or this
additional supply of water or other liquid may be dropped upon the rove as it
issues from the water or liquid trough of the spinning frame. I heat the pipes
troughs or reservoirs from which this supplementary supply of water or other liquid
is drawn by means of gas jets or burners placed below the said pipes or troughs or
in any other suitable or convenient manner, or I draw this additional supply of
liquid from the general reservoir already heated by gas as previously described.
In the process of spinning hemp, flax and other vegetable fibres by the system
known as or commonly termed "cold water
<<
or semi dry" spinning especially
when spinning yarns intended to be used for shoe threads or twines I have found
from experience that considerable advantages may be and are derivable from using
the water, alkaline, saponaceous or other solutions ordinarily applied to the rove of
such yarns in or during the process of spinning upon the spinning frame, warm, or
hot, in place of cold, as has hitherto been the custom in this country so far as I
am aware this water alkaline or other liquid can be applied to the rove on the
spinning frame in various ways either by means of a roller suitably covered with
flannel or otherwise or by means of a drop jet or spray upon or directed against
the rove at any desired point. I heat the metal trouglis or reservoirs containing
the water or other liquid by means of gas jets or burners applied in any suitable
manner or draw the necessary supply of water or other liquid from a general
reservoir which has already been heated by gas as previously described.

I prefer to make the water or liquid troughs commonly called, damping roller
troughs, of the dry spinning frame, moveable, so that the trough can be raised or
lowered, to any desired height; by means of this arrangement the immersion of
the damping rollers, in the water or other liquid, contained in the trough, can be
regulated to a great nicety and consequently the amount or quantity of water or
other liquid desired to be applied to the yarn may be changed modified varied.or
continued at an uniform rate according to circumstances, without being under the
necessity of stopping the spinning frame for this purpose during the process of.
spinning. I accomplish this lowering and raising of the damping roller troughs by
means of a rack and pinion or gear wheel actuated by a worm wheel and handle, or
otherwise and usually placed inside the end of the spinning frame or this lowering
or raising of the damping roller troughs may be performed in any other suitable or
efficient manner.
In order further to facilitate the regularity of the supply of water or other
liquid applied to the yarn during the process of "semi, dry" spinning especially
for those yarns intended for shoe threads. I arrange or modify the gearing of
the damping rollers so that the speed or revolutions of these rollers, can be
increased or diminish and this I accomplish by means of change pinions or gears
(on the end of said rollers) but I make no claim to the hereinbefore described

page_text: method of regulating the height of the damping roller troughs of dry spinning
frames nor to varying the speed of the damping rollers.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 shows an embodiment of my invention in a form of apparatus wherein
the heat of gas is applied to the exterior of a metal trough a and utilized to heat
the liquid therein contained; b, b, are gas jets, c is the gas supply and dinlet for
air to aid combustion.
In
Fig. 2 shows the invention applied to an old or existing wooden trough a'.
this case a is a metal cistern, a a supply pipe for hot water therefrom to the
trough a. b, b are the gas jets, e the supply of gas, d the air inlet, and e the cold
supply to the hot water cistern.
The supply of hot water to the pipe or the pipes i and shown in the
Specification of my Patent No. 21725 dated 11th December 1891 may be effected
when desired by means of a pipe from the cistern a, Fig. 2 above mentioned, in
communication, with said pipe or pipes and controlled by valve.
Or this heated water may be obtained by means of a pipe leading from a heating
coil such as shown in Fig. 6 taken off at the point (1).
Fig. 3 shows a side elevation and Fig. 4 a plan (of a portion of Fig. 3) of means
whereby the damping roller trough e of the dry spinning frame may be raised and
lowered to regulate the degree of immersion of the roller e. f is a worm wheel
on the axis operated by the winch handle f; g is a tooth gear, one of a series,
mounted at intervals on the said shaft f³ and actuated thereby and engaging the
teeth of a rack g', also one of a corresponding series cach carried in bearings in
the framing h. This rack g' forms part of a bar on which is mounted the bracket g²
carrying the trough e. b, b, are gas jets supplied by the pipe c.
Fig. 5 shows a transverse section of the trough e and roller e¹ clear of the
brackets &c. Fig. 6 shows a coil of piping heated by a set of gas jets b, b,
supplied by pipe c and which coil may supply the trough or the cistern, or the
pipe of a dry spinning frame as set forth.
In the foregoing description I have referred for brevity to hot water but I
intend to include in that phrase solutions or other liquids employed in like manner.
I would have it distinctly understood that I do not confine myself to the particular
arrangements of liquid troughs shown nor do I confine the application of my
invention thereto, and separately considered I make no claim to the details of the
apparatus as they do not constitute an essential feature of my invention, but
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. The use and application of gas as a heating agent for the water or other
liquids used in the troughs of the spinning frame during the process of wet
spinuing flax, hemp and other vegetable fibres, substantially as set forth.
2. The use and application of gas as a heating agent for heating the water and
other liquids used upon the spinning frame during the process of wet spinning flax,
hemp and other vegetable fibres substantially as set forth.
3. The use and application of gas as a heating agent for heating the water or
other liquids used upon the spinning frame in the process of spinning flax, hemp
and other vegetable fibres intended for shoe threads and similar yarns commonly
termed "cold water" or "semi dry" spinning, substantially as set forth.
4. The construction and use of liquid troughs of wet spinning frames of copper,
aluminium or other suitable metal or alloy heated by means of jets or burners and
gas supplied thereto in manner and for the purpose, substantially as set forth.
