PROVISIONAL SPECIFICATION.
Improvements in Immersion Rollers appertaining to Sizing,
Bleaching, and Dyeing, or analogous purposes.
I, WILLIAM COWELL, of Calder Vale Brass Works, Burnley, in the County of
Lancaster, Brass founder, do hereby declare the nature of this invention to be as
follows:-
The object of these improvements is to obviate the undermentioned disadvan-
tageous features, which are at present identified with cylindrical and skeleton rollers
used in the above processes.
They are as follows:-Irregularity of driving emanating from faulty construction;
unequal submersion of the yarn; unnecessary disturbance of the fluid at the surface,
and inadequate or superfluous frictional surface, either causing the warp to slip
under the roller without driving it, or creating excessive strain, and consequently
frequent breakages, and waste of yarn.
These breakages not only disorganize the arrangement as to the number of "ends"
of which the warp should consist, but also necessitate additional labour in reinstating
those destroyed.
In order to carry out my invention, I construct the immersion medium or device
of a number of cylindrical tubes, or solid bars, or rods of brass, or other suitable
material, fixed (with intervening spaces between them), securely at each end, and
intermediately, to flanges or supports, of octagonal or other suitable shape.
Each bar or rod is situated, and let in at the point or apex of each angle of the
octagon, or other shaped support, and in such a manner, that a portion of the
periphery or perimeter of the bar projects beyond the surface of the edge or
perimeter of the flange or support, in order to keep the warp out of contact there-
with otherwise the size would not surround and sufficently impregnate the
threads.
To ensure the utmost strength, and provide against dismemberment of the several
parts, I secure them together in the following manner viz. :-
The intermediate supports are united to the rods by a pin or screw driven through
the rod transversely, into the edge of the support.
By means of a set screw penetrating the outer surface of the flanges, and entering
the end of the rod, they are fixed firmly together; the flanges being drilled on their
interior surface through one half of their thickness only or the rods may be screwed
at the ends, and penetrate the flanges, and be secured thereto by nuts.
The heads of the screws, bolts, or nuts, may be covered by a suitable cap.
Spindles or studs (to be supported by bearings), penetrate the flanges and are
secured thereto by means of a nut or other suitable device and may be readily
renewed if necessary.
Immersion devices or rollers constructed as indicated above, not only remove the
disadvantages previously named, but also offer less resistance to the fluid, and enter
and emerge from it with less concussion and disturbance.

Improvements in Immersion Rollers appertaining to Sizing,
Bleaching, and Dyeing, or analogous purposes.
I, WILLIAM COWELL, of Calder Vale Brass Works, Burnley, in the County of
Lancaster, Brassfounder, 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 :-
The object of these improvements is to obviate the undermentioned disadvan-
tageous features, which are at present identified with cylindrical and skeleton rollers
used in the above processes.
They are as follows:-Irregularity of driving emanating from faulty construction;
unequal submersion of the yarn; unnecessary disturbance of the fluid at the surface,
and inadequate or superfluous frictional surface, either causing the warp to slip
under the roller without driving it, or creating excessive strain and consequently
frequent breakages and waste of yarn.
These breakages not only disorganize the arrangement as to the number of
"ends" of which the warp should consist, but also necessitate additional labour in
reinstating those destroyed.
In order to carry out my invention, I construct the immersion medium or device
of a number of cylindrical tubes or solid bars or rods of brass, or other suitable
material, fixed (with intervening spaces between them) securely at each end and
intermediately, to flanges or supports, of octagonal or other suitable shape.
Each bar or rod is situated and let in at the point or apex of each angle of the
octagon or other shaped support; and in such a manner, that a portion of the
periphery or perimeter of the bar projects beyond the surface of the edge or
perimeter of the flange or support in order to keep the warp out of contact there-
with, otherwise the size would not surround and sufficiently impregnate the
threads.
To ensure the utmost strength, and provide against dismemberment of the several
parts, I secure them together in the following manner viz. :-
The intermediate supports are united to the rods by a pin or screw driven through
the rod transversely into the edge of the support.
By means of a set screw penetrating the outer surface of the flanges, and entering
the end of the rod, they are fixed firmly together; the flanges being drilled on their
interior surface through one half of their thickness only, or, the rods may be screwed
at the ends and penetrate the flanges and be screwed thereto by nuts.
The heads of the screws, bolts or nuts, may be covered by a suitable cap.
Spindles or studs (to be supported by bearings) penetrate the flanges and are
secured thereto by means of a nut or other suitable device and may be readily
renewed if necessary.
Immersion devices or rollers constructed as indicated above, not only remove the
disadvantages previously named, but also offer less resistance to the fluid, and enter
and emerge from it with less concussion and disturbance.
In the accompanying drawings,
Figure 1 is a longitudinal view.
Figure 2 an end view.
Figure 3 à section through the centre of Figure 2.
Figure 4 a side elevation of the intermediate supports.
Figure 5 a section through the centre of Figure 4.
Figures 6, 7, 8 and 9, are sectional segments or details shewing method of
fastening the rods to the end flanges and intermediate supports; and Figures 10
11 and 12 show outer, inner and side view of cap of immersion rollers constructed
in accordance with my invention.

page_text: On reference to the drawings, A. represents the cylindrical tubes or solid bars or
rods; B, the end flanges; C the intermediate supports; D the intervening spaces
between the rods; E, the taper pin, plug or screw driven through the rod into the
edge of the intermediate supports; F, the screwed end of rod shouldered down to
fit holes penetrating the flange and secured by the aut F¹; H, the end of tube let
into the flange and fastened by the set screw H¹; and I the cap.
The bars or tubes project beyond the edges of the intermediate supports which
are hollowed out (as shown at A' and C¹) to prevent the yarn coming in contact
with the latter.
The cap (of which Fig. 10 is the outer and Fig. 11 the inner view) for covering
the heads of the bolts or nuts F¹ and H¹ on the flanges, is secured to the latter by
two screws passing through the holes I¹. These holes are continued through the
studs (cast on the inside of the cap) provided for butting against the outside face
of the flange B, as are also the studs I³.
Aperture J, permits the spindle K to pass through.
In order to be able to substitute a new spindle when the one in use becomes worn
out, I provide it with a collar L and screwed end M (Fig. 3), the latter passing
through the eye J of the flange B, and receiving the nut O which firmly secures
the flange and spindle together.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In immersion rollers, the solid rods or cylindrical tubes A, substantially as
described and illustrated.
2nd. The rods or tubes A secured to the flanges B and intermediate supports C
substantially as described and illustrated.
3rd. The cap or cover substantially as described and illustrated by Figures 10
and 11.
4th. The construction of immersion rollers embracing the arrangement and
combination of the parts substantially as and for the purpose herein before specified
and illustrated in the accompanying drawings.
