IMPROVE- MENTS IN MACHINERY EMPLOYED IN FINISHING LACE AND OTHER FABRICS
Year: 1884

page_text: I LEONARD LINDLEY of the Town and County of the Town of Nottingham,
Lace Dresser do hereby declare the nature of the said Invention for IMPROVE-
MENTS IN MACHINERY EMPLOYED IN FINISHING LACE AND OTHER FABRICS to be
as follows:-
The Invention relates to that class of machinery employed in finishing lace and
other fabrics in which the fabric is stretched upon endless chains of tentering hooks
from which it is delivered to an ironing or drying cylinder.
In the specification of Letters Patent granted to me dated March 17, 1883
No 1418 I described and represented certain improvements in such class of
machinery one of which improvements consisted in the employment of two endless
tapes or bands acting one at each edge of the fabric to assist in liberating tho
fabric from the tentering hooks and to bring the edges thereof immediately into
contact with the heated cylinder and there hold them until the fabric is dry.
These endless tapes or bands are necessarily worked under great tension and being
made of textile material aro soon destroyed thereby causing considerable expenso
for renewals.
According to my present invention I employ in lieu of such tapes or bands,
endless chains provided with narrow bearing pieces so formed as to present an
almost continuous surface to the heated cylinder by which incans I am enabled to
apply as much tension as is required to securely hold the lace or other fabric
between such endless chains and the heated cylinder and thereby prevent the
shrinking of such fabric during the drying operation.
I also attach to the chains of tentering hooks wood or other non-metallic blocks
which rise a short distance above the points of the hooks and the links of the
chains and I press such chains against the heated cylinder by means of rollers
underneath the same and acted upon by springs or weights. By these means the
chains of tentering hooks are always maintained in the same relation to the heated
cylinder and the tentering hooks are prevented by the wood or other non metallic
blocks from catching against the said cylinder or against the fabric thereon whilst
by the use of said non-metallic blocks I avoid soiling such cylinder and dispense
with the arrangement described in my aforesaid specification, for supporting the
chains of tentering hooks within a given distance of the heated cylinder.

page_text: I LEONARD LINDLEY of the Town and County of the Town of Nottingham,
Lace Dresser, do hereby declare the nature of the said Invention for IMPROVEMENTS
IN MACHINERY EMPLOYED IN FINISHING LACE AND OTHER FABRICS and in what
manner the same is to bo performed, to be particularly described and ascertained
in and by the following statement :—
The invention relates to that class of machinery employed in finishing lace and
other fabrics in which the fabric is stretched upon endless chains of tentering hooks
from which it is delivered to an ironing or drying cylinder.
In the specification of Letters Patent granted to me dated March 17th 1883
No 1418 I described and represented certain improvements in such class of
machinery one of which improvements consisted in the employment of two endless
tapes or bands acting one at each edge of the fabric to assist in liberating the
fabric from the tentering hooks and to bring the edges thereof immediately into
contact with the heated cylinder and there hold them until the fabric is dry.
These endless tapes or bands are necessarily worked under great tension and boing
made of textile material are soon destroyed thereby causing considerable expense
for renewals.
According to my present invention I employ in lieu of such tapes or bands
endless chains provided with narrow bearing pieces so formed as to present an
almost continuous surface to the heated cylinder by which means I am enabled to
apply as much tension as is required to securely hold the laco or other fabric
between such endless chains and the heated cylinder and thereby prevent the
shrinking of such fabric during the drying operation.
I also attach to the chains of tentering hooks wood or other non-metallic blocks
which riso a short distance above the points of the hooks and the links of the
chains and I press such chains against the heated cylinder by means of rollers
underneath the same and acted upon by springs or weights. By these means the
-chains of tentering hooks are always maintained in the same relation to the heated
cylinder and the tentering books are prevented by the wood or other non-metallic
blocks from catching against the said cylinder or against the fabric thereon whilst
by the use of said non-inetallic blocks I avoid soiling such cylinder and dispenso
with the arrangement described in my aforesaid specification for supporting the
chains of tentering hooks within a given distance of the heated cylinder.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying Drawings more fully
to describe the same.

page_text: :
a is one of a pair of chains of tenterings 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.
In the specification of Letters Patent granted to me dated March 17th 1883
No 1418 I described and represented certain improvements in such class of
machinery one of which improvements consisted in the employment of two endless
tapes or bands acting one at each edge of the fabric to assist in liberating the fabric
from the tentering hooks and to bring the edges thereof immediately into contact
with the heated cylinder and there hold them until the fabric is dry. These
endless tapes or bands are necessarily worked under great tension and being
made of textile material are soon destroyed thereby causing considerable expense
for renewals.
According to my present invention I employ in lieu of such tapes or bands,
endless chains provided with narrow bearing pieces f₁so formed as to present an
almost continuous surface to the heated cylinder c, I also supplement such narrow
bearing surfaces f¹ with a bearing surface f formed upon the solid part of the
links of such endless chains and I preferably form such bearing surfaces fl f
roughened in order to enable them to obtain a firm hold of the fabric under
treatment.
By these means I am enabled to apply as much tension as is required to securely
hold the Ince or other fabric between such endless chains and the heated
cylinder c and thereby prevent the shrinking of such fabric during the drying
operation
These endless chains fare carried over tho rollers & guide rollers g g¹ and tension
rollers 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 the slides i which are acted upon
by screws in order to give the requisite tension to the endless chains 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 endless
chains f
The means herein shown and described for carrying and putting tension on the
endless chains are similar to those shown and described in my aforesaid specifi-
cation for carrying and putting tension on the endless tapes or bands f therein
described and consequently form no part of my present invention.
I also according to my present invention attach to the chains of tentering hooks a
wood or other non-metallic blocks a³ a' which rise a short distance above the points
of the hooks a² and the links a' of the chains and I press such chains a against the
heated cylinder c by means of rollers & carried each by an arm or levere acted
upon by a spring e or by a weight but instead of causing the rollers d to bear
against the surface of the heated cylinder c as described in my specification before
referred to; I make such rollers d of less diameter and prevent their bearing
against the cylinder c, but I cause the chain supports d' fixed to, or forming part of

page_text: such rollers d to press, the blocks a³ a' of the chains a against the surface of, the
cylinder c.
:
These non-metallic blocks a³ a are also applicable to tentering chains provided
with clamps in lieu of hooks..
By these means the tentering chains a are always maintained in the same relation
to the heated cylinder c and the tentering hooks or clamps are prevented by the
wood or other non-metallic blocks a³ a from catching against the said cylinder c
or against the fabric thereon whilst by the use of said non-metallic blocks a³ a¹ I
avoid soiling such cylinder c and dispense with pressing the rollers d against the
cylinder c in order to support the tentering chains a within a given distance of the
heated cylinder c.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declaro that what
I claim is:
1. In machinery employed in finishing lace and other fabrics the employment of
endless chains formed with bearing surfaces f¹fin lieu of endless tapes or bands
substantially as herein shown and described and for the purpose stated.
2. In machinery employed in finishing lace and other fabrics the employment of
tentering chains a provided with non-metallic blocks a³ a and pressing the said
blocks against tho surface of the cylinder c substantially as herein shown and
described and for the purpose stated.
Dated this 18th day of December 1884.
