IMPROVEMENTS IN MACHINERY EMPLOYED IN FINISHING LACE AND OTHER FABRICS
The Invention has for its object improvements in machinery employed in
finishing lace and other fabrics, and relates to that class of machinery described in
the specification of Letters Patent granted to me, dated May 7. 1880 N° 1875.
According to my present Invention I place the ironing or drying cylinder as.
close as possible to the chain of tentering hooks and pass the fabric under
treatment direct from the tentering hooks onto the heated cylinder instead of first
passing it on to a tension roller and thence on to the heated cylinder.
In order to maintain the chain of tentering hooks always within a given distance
of the surface of the heated cylinder even when the latter is not truly cylindrical I
cause a roller carried by a weighted or sprung arm or lever to bear against the
surface of the heated cylinder and I fix to such weighted or sprung arm or lever a
support over which the chain of tentering hooks is caused to pass.
I also supplement the use of the ironing cloth and in certain cases use in lieu
thereof a number of narrow endless tapes stretched over guide rollers and applied
to the fabric in a manner similar to the ironing cloth or apron.
These endless tapes I arrange by preference in two series, one series being a
little in advance of the other, and the spaces between being a little narrower than
the width of the tapes, thus every part of the fabric under treatment will be
pressed against the heated cylinder thereby enabling much greater pressure to be
applied to the fabric than when using an ironing cloth for such purpose.
In order to prevent contraction or distortion of the fabric operated upon, when
it is transferred from the tentering pins or holders to the drying cylinder I employ

page_text: two endless tapes or bands (similar to those previously described) to act at the
edges of the fabric, to assist in liberating the fabric from the tentering pins or
holders and to bring the edges thereof immediately into contact with the heated
cylinder. These tapes or bands are caused to remain in contact with the edges of
the fabric and to press them against the heated surface until the fabric is so dry
that it will not shrink when released.
In using the ironing cloth described in my former specification I find it
advantageous to use therewith two parallel endless chains, conducted over toothed
wheels at the ends of the tension rollers, and the drying cylinder, and I lace the
ironing cloth to the said endless chains for the purpose of keeping the ironing cloth
fully distended in width.
In finishing some fabrics it is needful to cover the drying cylinder with cloth, so
as to prevent a glazed appearance, on the fabric under treatment, and I find an
arrangement similar to that described for conducting the ironing cloth by means of
endless chains to be a desirable one to be used (especially where more than one
drying cylinder is used) in connection with the covering for the cylinder where a
cloth has to be interposed between the fabric and the heated surface of the cylinder.
Or the cloth covering may be laced directly to the cylinder.

by the said Leonard Lindley in the Great Seal Patent Office on the

LACE
IN FINISHING
AND OTHER
The Invention thas for its object improvements in machinery employed in
finishing lace and other fabrics, and relates to that class of machinery.described in
the Specification of Letters Patent.granted to.me dated May 7th 1880 N° 1875.
According to my present Invention I place the ironing or drying cylinder as
close as possible to the chain of tentering.hooks and pass the fabric under treatment
direct from the tentering hooks on to the heated cylinder instead of. first passing it
on to a tension roller.and thence on to the heated cylinder.
In order to maintain the chain of .tentering hooks: always within a given distance
of the surface of the heated cylinder even when the latter is not truly.cylindrical
I cause a roller carried by a weighted or sprung arm or lever to bear against. the
surface of the heated cylinder and I fix to such weighted or sprung arm or lever a;
support over which the chain of tentering hooks is caused to pass.
And in order to prevent contraction or distortion of the fabric operated upon
when it is transferred from the tentering pins or holders to the drying cylinder I
employ two endless tapes or bands to act at the edges of the fabric, to assist in
liberating the fabric.from the tentering pins or holders and to bring the edges

page_text: thereof immediately into contact with the heated cylinder. These tapes or bands
are caused to remain in contact with the edges of the fabric and to press them
against the heated surface until the fabric is so dry that it will not shrink when
released.
In using the ironing cloth described. in my former Specification I find it
advantageous to use therewith two parallel endless chains, conducted over toothed
wheels at the ends of the tension rollers and the drying cylinder, and I lace the
ironing cloth to the said endless chains for the purpose of keeping the ironing cloth
fully distended in width.
And in order that the said Invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying Drawings more fully
Figure is a Sectional side vi
and figure is an end view or parts of the
machine showing my present improvements applied thereto.
a is one of a pair of chains of tentering hooks which pass over wheels b and
are thereby caused gradually to move forward towards the ironing or drying
cylinder.c.
One of these chains a is employed at each side of the machine and the wheels b
carrying and giving.motion to the same are carried by frames capable of being
moved towards or from each other according to the width of fabric under-treatment
and the frames and consequently the chains are so arranged as to stretch the fabric
to the desired extent before its delivery to the ironing or drying cylinder c. The
cylinder c is heated by steam or other suitable means and sometimes it is employed
without any cloth or felt covering thereon whilst at other times it is provided with
such covering.
The parts above described and referred to do not form any part of my present
invention and as such are now well known and understood I have thought it
unnecessary to give details of the travelling frames and other parts not included in
my present Invention.
According to my present Invention I place the ironing or drying cylinder cas
close as possible to the chain of tentering hooks a and pass the fabric under
treatment direct from the tentering hooks a on to the heated cylinder c instead of
as heretofore first passing it on to a tension roller and thence on to the heated
cylinder c, by the present improved means the fabric under treatment is delivered
to the cylinder c at the full width it has attained on the tentering hooks a.
In order to maintain the chain of tentering hooks a always within a given
distance of the surface of the heated cylinder c even when the latter is not truly
cylindrical I cause a roller d (carried by an arm or lever e acted upon by a spring e¹
or by a weight) to bear against the surface of the heated cylinder c and I fix to
such roller da support d' over which the chain of tentering hooks a is caused to
pass and in order to prevent contraction or distortion of the fabric operated upon
when it is transferred from the tentering pins or hooks a to the ironing or drying,
cylinder c I employ two endless tapes or bands f to act one at each edge of the
fabric to assist in liberating the fabric from the tentering pins or hooks a and to
bring the edges thereof immediately into contact with the heated cylinder c. These
tapes or bands fare carried over the rollers & guide rollers g g' and tension rollers h
and are thereby caused to remain in contact with the edges of the fabric and to
press them against the surface of the heated cylinder c until the fabric is so dry
that it will not shrink when released. The tension rollers h are, as represented in
the drawings, carried by standards fixed to slides which are acted upon by
screws in order to give the requisite tension to the tapes or bands f but other
suitable means may be employed for this purpose and I prefer to give rotary
motion to the guide rollers g in order to prevent undue strain on the tapes or
bands f

page_text: In using the ironing. cloth described in my said former Specification I find it
advantageous to use there with two parallel endless chains conducted over toothed
wheels at the ends of the tension rollers and the drying cylinder and I lace the
ironing cloth to the said endless chains which are provided with eyes, loops or
other parts fixed thereto for that purpose. By these means the ironing cloth is
kept fully distended in width I have not represented the above arrangement
in the accompanying drawings as such will be readily understood from the
above description.
I would here remark that the arrangement described in my Provisional
Specification for the use of a number of endless tapes or bands for imparting extra
pressure to the fabric on the heated cylinder and the arrangement for applying a
covering to the heated cylinder do not possess such an amount of utility as to
render it advisable to give a further description thereof. For this reason I desire
to disclaim and I do hereby disclaim such arrangements.
Having thus described the nature of my said Invention and the mode in which I
carry the same into effect I would have it understood that what I claim is :-
First, The employment, in combination with endless chains of tentering hooks a
and heated cylinder c, of two endless tapes or bands f acting one at each edge of the
fabric to assist in liberating the fabric from the tentering books a and to bring
the edges thereof immediately into contact with the heated cylinder c and there
hold them until the fabric is dry substantially as herein shown and described.
Second. The employment, in combination with endless chains of tentering
hooks a heated cylinder c and endless tapes or bands f of roller d and support di
for the chains substantially as herein shown and described and for the purpose
stated..
.
Third. The method of distending the ironing cloth described in my said former
Specification by lacing the same to parallel endless chains substantially as berein
described..
In witness whereof I the said Leonard Lindley have hereunto set my hand and
seal this Fourteenth day of September in the year of our Lord 'One thousand eight
hundred and eighty three.
