Improvements in Apparatus for Applying Steam to Yarn during
the Process of Weaving.
I, JAMES WHITE of 3, Ellis Street, Burnley, in the County of Lancaster, Weaver,
do hereby declare the nature of my invention for IMPROVEMENTS IN APPARATUS FOR
APPLYING STEAM TO YARN DURING THE PROCESS OF WEAVING, and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention consists essentially in applying steam to each individual warp, in
contradistinction to the usual method of infusing steam into the weaving rooms or
sheds in jets from the ordinary steam pipes, which method is found so objectionable;
the steam being inhaled by the persons employed in such rooms or sheds; whilst the
steam is only applied in an indifferent manner and to a limited degree.
The improvements consist in the arrangement of a perforated tube in juxta-position
with each individual warp beam, steam being conveyed by suitable pipes to the
perforated tube from the main steam pipe in the shed.
To prevent undue application of steam to the warp whilst the loom is at rest, a
stop tap or similar appliance is arranged and connected to the setting-on motion, that
immediately the loom is stopped, the tap is at once automatically closed to the entrance
of steam.
In order that my invention may be properly understood, and readily carried into
practical effect, I have hereunto attached the accompanying sheet of drawings,
marked with figures and letters of reference, the same letters referring to the same
parts, in the various figures.
Figs. 1 and 2 represent a back view of two power looms, having my improvements
applied Fig. 3, is an end view; and Fig. 4 is an enlarged view, shewing more
clearly the parts for closing the steam tap or cock against the entrance of steam,
when the loom is at rest. A is the ordinary steam pipe for heating the weaving
room or shed. From this pipe steam is conveyed along the passage pipe B, down
the pendent C, to the T joint D. This joint divides the steam into two currents, one
of which is conveyed through the valve cock or tap E into perforated pipe or tube F,
seen in Fig. 1; and the other along horizontal pipe G, to valve cock or tap E, into
perforated tube F, seen in Fig. 2. A covering J is provided for each of the
perforated tubes F to keep them clear of fluff or dust. The steam, passing from the
perforated tubes, finding its way from below the edges of the coverings, ascends as
vapour, moistening the warps on the warp rolls K.
The quantity of steam entering the perforated tubes may be regulated by the valve
tap or cock E, which is connected to rod m supported in the brackets n.
The upper
end of the rod m is provided with finger O, which takes into the slot of bracket P,
fixed to the setting-on handle of the loom, so that when the handle is thrown out of

page_text: its detent, it turns the rod m and valve cock E; thereby turning off the steam from
the perforated tube immediately before the loom is at rest. When the handle is again
pushed into the detent, the valve tap is again opened for the admission of steam.
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 perforated tube F, placed in juxta-position with the warp roll K, substan-
tially as and for the purpose described.
2. The application of the covering J, substantially as described for the purpose set
forth.
3. The general arrangement and combination of the parts, substantially as described
and illustrated.
