I JOHN CRYER, of the firm of E. Cryer and Company, Machine Makers,
Waterside Works, Dukinfield, in the County of Chester, do bereby declare the
nature of said Invention for IMPROVEMENTS IN SHEDDING APPARATUS EMPLOYED
IN LOOMS FOR WEAVING VELVETS AND CERTAIN OTHER FANCY GOODS, to be as
follows:-
"
The object of my Invention is to throw the pattern on the upper instead of the
lower surface of the fabric when weaving velvets and certain other fancy goods
with an ordinary loom and barrel motion.
To effect this I employ a barrel, and segments and I build up the rings of the
barrel with segments so as to leave hollows in place of pegs or projections as at
present; the rings are provided with the desired number of hollows to produce the
pattern required.. The normal position of the heald shafts is down instead of
raised, as now customary.
The levers and springs or weights for the healds are arranged to lift the healds
when the bowls on the levers enter the hollows in the barrel as the latter revolves.
By my arrangement the heald shafts are normally down and consequently as
they are raised the pattern is thrown on the upper surface and can be seen by the
weaver.

Weaving Velvets and Certain other Fancy Goods.
I JOHN CRYER, of the firm of E. Cryer and Company, Machine Makers,
Waterside Works, Dukinfield, in the County of Chester, do hereby declare the
nature of said Invention for IMPROVEMENTS IN SHEDDING APPARATUS EMPLOYED
IN LOOMS FOR WEAVING VELVETS AND CERTAIN OTHER FANCY GOODS, 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 my Invention is to throw the pattern on the upper instead of the
lower surface of the fabric when weaving velvets and certain other fancy goods
with an ordinary loom and barrel motion.
To effect this I employ a barrel and segments and I build up the rings of the
barrel with segments so as to leave hollows in place of pegs or projections as at
present; the rings are provided with the desired number of hollows to produce the
pattern required.. The normal position of the heald shafts is down instead of
raised as now customary.
The levers and springs or weights for the healds are arranged to lift the healds
when the bowls on the levers enter the hollows in the barrel as the latter revolves.
By my arrangement the heald shafts are normally down and consequently as
they are raised the pattern is thrown on the upper surface and can be seen by the
weaver.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a longitudinal section and Fig. 2 an end view of a barrel constructed
according to my Invention for actuating the treadle levers and healds and Fig. 3 is
a view of the said barrel.and the treadle levers which actuate the healds.
a is the shaft of the barrel and b the bevel wheel secured to the shaft a and by.
which it is driven; the barrel is formed of any number, in this instance eight, of
rings c, and each of theso rings c is built up with a number of loose segments d, in
such manner that hollows d' are formed on the surface of the barrel in place of the
pegs or projections employed at present to actuate the treadle levers and healds.
The rings and segments & are secured in their proper. positions by means of
bolts e and the segments are provided with any number of hollows & according to
the pattern desired.
The treadle levers ƒ are pivoted at one end and connected at the other to the
heald shafts in the ordinary manner and each lever is provided with a bowl flas
usual but the normal position of the heald shafts is down instead of raised, as now
customary, with an ordinary peg and barrel motion. The treadle levers f and
their connections are so arranged and the heald shafts are so weighted by springs
that the normal tendency of the treadle levers f is always to rise.
When motion is given to the shaft a by means of the wheel b, and the barrel
revolves, the bowls fenter the hollows on the surface of the barrel thereby
.

page_text: allowing the treadle levers f to rise and actuate the heald shafts and healds until
the bowls f leave the hollows d'and the treadle levers fare again depressed.
Having now particularly 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
Constructing the barrel of a loom with any desired number of hollows instead of
pegs or projections for actuating the treadle levers and the healds, substantially in
the manner herein set forth, for the purposes specified.
