l Letters Patent No. 105,455, dated July 19, 1870.

The Schedule `referredto in these Lettera Patent and making part of the same.

To all ulhom t may concern.- l

` Be it known `that L'JOHN' HoLT, "of Lowell, in

the county of Middlesex and State of `Massachusetts,.

have `invented, certain new and useful Improvements 1n Press-Dyeing, and in the apparatus fby which the -process is performed, of whichl the following is a full,

clear, and exact description, reference :being had to` lication; in whichy l Figure 1 is a sectional elevation.

` the accompanying drawing making part of this speci- ,Figure 2 is an end view.

Figure `3, anI end elevation ofthe clamping-joint and a segmentary s ection of the other parts.

`Figure 4 represents a plan or top view of fig. 3.

This. invention relates` to press-dyeing, and to the machinery or apparatus bywhich textile fabrics are pressfdyed in parallel stripes.

This invention has for its object topless-dye or color.' the stripes inlbnnti-ng, whiclris used for ags or ensigns, and in annels and other fabrics which are capable of being colored in 'stripes by the press-dyeing process. l l

In carrying out my invention, I provide one, two,

or more common pulleys A, secured to a central shaft,

13 andat any desired distance apart. l

Each ofthese 'pulleys is covered withav suitable thickness of rubber, or other substance, or material,

a, impervious to common coloring or dyeing liquid.

f `The fabric, 0,*to be colored or press-dyedA in stripes,

is wound around the, covered' pulleys as upon a roll,

and .atanypohlton` the outer surface of therrolled fabricI place a thin piece, c, of rubber, or` other ina- .t'erial, like that which covers each pulley, and over this'a metal plate, c'.

Aroundvthe outer surface of the fabric,ai \d coverr in'g the rim of each pulley, 1 apply a second rubber packing or blanket, e, the`endsof which nearly meet together on the plate c. r r, Out'side'ofthe blanket lapply a clamping-11001), d,

at each Aend of the .pulley or pulleys, the outer edge of each of the form-er coming opposite or evenhwith each outer edge of the latter'.- i r 'Earsf project from 'each endofj the hoop, and screwbolts h. passthrougli them.

A nut, g, on each screw-bolt, serves to draw the ends of'the hoop together, and-clamp the fabric soV `closely between the packing substanceslas to cx- `clude the coloring liquid, while the portions O ofthe fabric, between or `beyondjthe pulleysrarc free to receive the coloring'liqnid whenimmersed-therein.

Theinner packing `c and the thin'fplatec cover the fabric beneath the abutting ends 4 of the outer packing, `and prevent the coloring liquid entering beneath "such `ends, and if thepulleys are wide, for press-dye- Ning wide stripes ,in the tbric, I`A employ aclamp, D,

#for pressing the abuttingfends-,of -the outer packing closely onto-the `iilate' c', soasttoelose any openerandftileendsof vthe outer i Theclamp D may be .heldin position by passing beneath-theclamping-screws h, as-*seen in fig. 4,' or

by' projections on the ears f, as seen in Iig. 1, or in anyl equivalent manner.

When either edge of the fabric is to be leftin a stripe of the original color, the packing should be folded oveiitat the end or edge of the pulley, as at E in` iig..1orpa thin packing folded over the edge i of the fabric and pressed and clamped between the outer and inner ones, and thus excludes the coloring liquid from .the edge of the fabric.` p v After the. fabric has been clamped onto thepnlf leys, as before described, the journals or end por-` tions of the shaft B are generally-placed in bearings L Vor boxes in or upon the ends of atank, H, which, should be nearly filled with coloring liquid ina snit;V

able condition, byheating or by boilingjto pass.

through and color all of 'that portion of tlieffabric' C' i which comes `between or beyond the lends of the pulleys; and, to color all such portions,. the appara` tusv is rotated on its axis a sufficient lengthof time to allow the unpressed fabric to receive the color.v

` If preferred, the whole apparatus and the clamped I o1p1'essed-fabric maybe fully immersed in the col-V I `oring liquid,and thereremain until the fabric is dyed. v

AfterA the dyeingor coloring has been fully perl' formed,V and before the clamps 'are released, the nnpacked fabric is treated in the usual way, either to `set'the colorf or to wash r rinse the fabric which is removed or unrolled after remoyin'g the clamps and thepacking.

The clamps may be made .in two parts, each part having' ears f, as seen in fig. 1, or in 'one part or piece, as in tig. 2, whichever way may best suit tl|e= convenience of the user. r

Having fully described my invention,

What I claim, and desire to secure by Letters Pat# ent, is

1. The method substantiallyas described, of press-r` dyeing. textile fabric in' parallel stripes, by rolling or winding such fabric4 around one or more' pulleys, ar-

v`ranged as described, and rby packing, and clamping,

andimmersing such fabric, substan'tlallyin the manner set forth. f r

2. A press -dyeiug apparatus, as described, the same consisting of one or more covered pulleys A,

and outer packings 'c c', and e, and clamping-hoops` d, havingears" f and screw-bolts 7i.,.all combined, arf ranged,- and applied substantially in vthe manner .and

for the purpose specified.v y 3. 'lhe clamp D, or the cquivaleutthereo when blanket e, as set forth.
