Improvements in the Manufacture of Imitation Buffalo Robes.
I, JOHN FIELD MORLEY, of the Town of Waterloo, in the County of Waterloo,
in the Province of Ontario Canada, Manufacturer, 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 :-
My invention relates to improvements in the manufacture of imitation buffalo
robes and it consists essentially of the various steps employed in combination and
treatment to produce a peculiarly woven woollen fabric as hereinafter more
particularly explained.
Fig. 1, is a plan view greatly exaggerated of the outer portion of the web before
it is treated.
Fig. 2, is a plan view of a similar size piece of the inner portion of the web before
it is treated.
Fig. 3, is a plan view greatly exaggerated showing the combined inner and outer
webs as woven.
Fig. 4, is a perspective detail greatly exaggerated showing the manner of
interweaving the outer and inner webs.
Fig. 5, is an edge view greatly exaggerated showing the outer and inner weft
threads before being treated.
Fig. 6, is a similar view after first treatment.
Fig. 7, is a perspective view of a portion of the robe after second treatment.
Fig. 8, is a perspective view after final treatment,
In the drawings like letters of reference indicate corresponding parts in each
figure.
A, are the warp threads and, B, are the weft threads of the outer web. The
weft threads, B, are made of a coarse long hairy worsted or bair roving and form
when finished the face of the robe.
The inner web is more closely woven and consists of warp threads, C, of cotton
and weft threads, D, of carded woollen yarn.
The outer side or face of the robe and inner side are interwoven as indicated in
Figs. 3 and 4, in which it will be seen that the warp upper threads, A., pass over
every second weft outer thread and every fourth inner thread. It is well known.
that carded woollen yarn shrinks and that a coarse long hairy worsted roving does
not shrink and I take advantage of this in the manufacture of my robe. The outer
or face fabric is necessarily as it will be understood from what will hereinafter be
described comprised of much less number of warp threads than the inner fabric
and it also follows that the roving being much coarser will be less in number in the
weft than the woollen yarn. The face and inner fabrics are interwoven in the
manner hereinbefore described or in any suitable way which will securely bind
the one to the other throughout the entire web.
I first treat the double web thus formed in a fulling machine which acts upon
the woollen fabric as indicated in the edge view in Fig. 5, so as to shrink the
carded woollen yarn weft threads and thereby throw up the roving between the
widely spaced warp threads, A, into the form shown in Fig. 6, making a series of
loops on account of the non-shrinking of the roving. The loops which extend
ontwardly beyond the warp threads, A, I now comb out, so as to form a hairy
surface as shown in Fig. 7.
When the fabric has been converted into this state I introduce it into a suitable

page_text: bath or receptacle and submerge it first in hot water and then in cold and continue
to do so alternately until the combed roving in crimped or curled to have the
desired appearance.
By the process above described a robe is produced, which is not only exceedingly
warm on account of the close texture of the inner web but the face or outer side
presents an appearance which it is difficult to distinguish from a genuine buffalo
robe.
Having now described and ascertained the nature of my said invention, and in
what manner the same is to be performed, I declare that what I claim is :-
1. The process herein described of producing & woven curly robe consisting in
interweaving a face web having a worsted roving weft and an inner web having a
carded woollen yarn weft then passing the combined web through a fulling machine,
so as to shrink the inner web and produce upon the face a series of loops of the
worsted roving and then combing such loops as and for purpose specified.
2. The process herein described of producing a woven curly robe consisting in
interweaving a face web having a worsted or hair roving weft and an inner web
having a carded woollen yarn weit then passing the combined web through a fulling
machine, so as to shrink the inner web and produce upon the face a series of loops
of the worsted roving, then combing such loops and finally submerging in hot and
cold water alternately until the desired curl is imparted to the face of the robe as
and for the purpose specified.
3. As a new article of manufacture a robe or similar article comprising a face
web 'having a worsted or hair roving weft combed out, the said web being inter-
woven with the inner web having a carded woollen yarn weft as and for the purpose
specified.
