Improvements in Dyeing Machines.
I, ERNEST WELDON, of New Basford, Nottingham, Dyer, 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 dyeing machines and particularly to machines for dyeing
knitted or woven garments.
My improved machine comprises a dye tub or vat having vertical or sub-
stantially vertical sides and a curved bottom, and a paddle wheel or two or more
paddle wheels or a series of vanes adapted when moved to cause a circulation of
the liquor in the tub or vat.
In order that my invention may be clearly understood I will now describe the
same with reference to the accompanying drawings, wherein
Figure 1 is a side elevation of one form of dyeing machine constructed according
to my invention, and
Figure 2 is a vertical longitudinal section of the same.
The dye tub or vat is constructed with vertical sides A and with a curved
bottom B which may be advantageously made semi-circular as shown. C, C are
shafts mounted in bearings D, D secured on the sides of the tub, and E, E are
suitable paddle wheels mounted on said shafts and extending across the tub. The said
paddle wheels may be closed at the ends by solid heads E', El or they may be
open at the ends. Although I have shown two paddle wheels I wish it to be
understood that I sometimes provide more than two, and at other times I provide
only one. I drive the paddle wheels in the same direction by bevel gearing or by
a chain and sprocket wheels or by other suitable gearing. In the drawing I have
shown a side shaft F for driving the paddle wheels. The said shaft is carried by
bearing brackets F1 secured to the side of the tub and is furnished with bevel
pinions G G gearing with bevel wheel G¹ G' secured on the shafts C, C. F³, F³ are
fast and loose pulleys on which the belt for driving the shaft F works. The paddle
wheels dip into the upper part of the dye liquor as shown and when rotated they
serve to cause the liquor and the garments therein to move towards one end of the
dye tub and then to pass down and follow the curved bottom of the tub and rise up
again at the other end of the tub in a continuous stream as indicated by the arrows.
The garments are thereby subjected equally to the action of the dye-liquor and do
not become entangled.
I provide the tub with a false bottom or perforated plate H and underneath said
plate provide a steam pipe J for heating the dye liquor.
In a modification of my invention in lieu of the rotating paddle wheels E,
I provide vanes or blades attached to endless chains passing around sprocket
wheels mounted on the shafts C in such a manner that when the said shafts are
rotated the vanes or blades are carried round and thereby set the dye liquor in
circulation.
By my improved machine hand labour is very largely dispensed with.
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. In a dyeing machine, a dye tub or vat having a curved bottom in combination
with means for causing the dye liquor to circulate, substantially as, and for the
purpose, specified.
