Improvements in Machinery or Apparatus Employed in Stretching,.
Dressing, and Finishing Lace and other like Fabrics.
I, LEONARD LINDLEY of the firm of Lindley, Wright and Cox, Limited, of
Short Hill, in the Town and County of the Town of Nottingham, Lace Bleachers,
Dyers and Dressers, do hereby declare the nature of this invention to be as
follows:-
:-
The invention relates to improvements on the ordinary tentering frame, and not
to the progressive machine in which the fabric is moved gradually forwards, and my
present improvements have for their object a novel construction of parts for enabling
the fabric to be stretched in the direction of its length, in addition to the cross
stretching which it has hitherto received.
According to my present invention, I secure the regular extension of the sections
carrying the tentering hooks, pins or clamps, by elastically connecting said sections™
together in the following manner.
At one end of each of said sections is an extension, provided with a head, which is
capable of moving to and fro within the space in an adjoining section, and between
which and the end of said section, a spring is placed. This may be effected by fixing
a pin centrally of one end of each of said sections, and by forming a hole in the
other end thereof, through which such pin can freely pass, a spring being placed.
around each pin, and a nut being screwed on the end of the pin, by which the
spring is held in place and the pressure exerted thereby can be regulated.
Or a similar effect can be obtained in the following manner. An arm may be
formed at one end and a space or recess in the opposite end of each section, to
permit of the free passage of the arm of an adjoining section; said arm is provided.
with a turned up piece, which is capable of travelling to and fro within the space in'
an adjoining section, and a spring is placed between said turned up piece and the
opposite end of the space in the said section.
In using tentering apparatus constructed as above described, the fabric is placed
upon the tentering hooks or pins, or in the clamps, when the sections carrying the
same are close together, the ends of the fabric are attached to cross bars, one of which
is fixed to stationary longitudinal bars, whilst the other is fixed to travelling bars. I
also fix the sections of tentering books, pins or clamps, adjacent to the first mentioned
cross bar, to the fixed longitudinal bars, whilst I fix the sections at the further end of
the fabric to the travelling cross bar.
Then, by giving motion to the moveable cross bar, the fabric will be equally,
stretched throughout its entire length.
If desired, stops may be applied to the sections to prevent them from opening out
beyond a certain distance from each other.
Dated this 3rd day of April 1889.

Improvements in Machinery or Apparatus Employed in Stretching,
Dressing, and Finishing Lace and other like Fabrics.
I, LEONARD LINDLEY of the firm of Lindley, Wright & Cox Limited of Short
Hill in the Town and County of the Town. of Nottingham, Lace Bleachers, Dyers
and Dressers 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 :-
+
The invention relates to improvements on the ordinary tentering frame and not
to the progressive machine in which the fabric is moved gradually forwards, and my
present improvements have for their objects a novel construction of parts for enabling
the fabric to be stretched in the direction of its length in addition to the cross
stretching which it has hitherto received.
According to my present invention I secure the regular extension of the sections
carrying the tentering hooks, pins or clamps by elastically connecting said sections
together in the following manner. At one end of each of said sections is an extension
provided with a head which is capable of moving to and fro within the space in an
adjoining section and between which and the end of said section a spring is
placed.
This may be effected by fixing a pin centrally of one end of each of said sections
and by forming a hole in the other end thereof through which said pin of an
adjoining section can freely pass, a spring being placed around each pin and a nut
being screwed on the end of the pin by which the spring is held in place and the
pressure exerted thereby can be. regulated. Or a similar effect can be obtained in
the following manner.
An arm may be formed at one end and a space or recess in the opposite end of
each section to permit of the free passage of the arm of an adjoining section said
arm is provided with a turned up piece which is capable of travelling to and fro
within the space in an adjoining section and a spring is placed between said turned
up piece and the opposite end of the space in the said section.
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.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of three sections or links of a tentering chain constructed
according to my invention. Figure 2 is a plan and Figure 3 is a cross section of one
of such sections or links separately and Figure 4 is a plan. Figure 5 is an underside
view. Figure 6 is a cross section and Figure 7 is a longitudinal section of two sections
or links of a tentering chain constructed according to my invention but representing
a slight modification, and Figure 8 is a cross section of one of such sections separately.
In all the Figures like parts are indicated by similar letters of reference.
I will first describe the arrangement represented at Figures 1 to 3.
a a are the tentering hooks or pins which are fixed in plates or leads a fixed to the
outer ends of arms b¹ formed on each section or link b of the chain. At the end 1 of
each section b is fixed centrally thereof a pin c and at the end 2 a hole d is formed
centrally thereof, through each hole d the pin c of an adjoining section 6 can freely
pass; around each pin c a spring e is placed and on the end of each pin ca nut c' is
screwed by which the spring e is held in place and the pressure exerted thereby can
be regulated.
In the modification represented at Figures 4 to 8 each section or link 6 of the
tentering chain has cast thereon at the end 1, an arm 62, whilst the other end 2
of each section or link has a space or recess d* formed at the lower part thereof to
permit of the passage therethrough of the arm 62 of an adjoining section.

page_text: The arm is provided at its outer end with a turned up piece 63 which passes up
into and is capable of travelling to and fro within the space in an adjoining section b
and a spring è is placed between said turned up piece and the opposite end 2 of the
space in the said section within which the turned up piece 63 works. A stud is fixed
in each turned up piece 3 and a similar stud is fixed in the end 2 of each section or
link these studs receive the ends of the spring e and serve to retain the latter in
proper position.
Each side of each section is formed with a space 3 to receive a projection 6³ on
each side of the arm which parts will act as stops to prevent the sections from
opening out beyond a certain distance from each other. It will be understood that
each section or link may be provided with clamps instead of with tentering pins or
hooks. In using tentering or stretching apparatus constructed as above described the
fabric is placed upon the tentering hooks or pins or in the clamps when the sections
or links carrying the same are close together, the ends of the fabric are attached to
cross bars, one of which is fixed to stationary longitudinal bars, whilst the other is
fixed to travelling bars, I also fix the sections or links of tentering hooks, pins or
clamps adjacent to the first mentioned or fixed cross bar to the fixed longitudinal bars
whilst I fix the sections or links at the further end of the fabric to the travelling cross
bars. Then by giving motion to the travelling longitudinal bars and cross bar the
fabric will be equally stretched throughout its entire length. This arrangement of the
fixed and moveable cross bars and of the fixed and travelling longitudinal bars and
the method of attaching the fabric to said cross bars and the sections or links to the
fixed and travelling side bars as also the method of giving motion to the travelling
side bars and cross bar will be clearly understood by reference to the specifications of
Letters Patent granted to me, numbered 12375 of the year 1884, and 3966 of the
year 1885.
The fabric is stretched in width by causing the side bars to separate from each other
in the manner well understood.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In machinery or apparatus of the character herein referred to, employed in
stretching, dressing and finishing lace and other like fabrics the method of elastically
connecting together the sections or links carrying the tentering hooks, pins or clamps,
substantially as herein shown and described and for the purpose stated.
2. In machinery or apparatus of the character herein referred to, employed in
stretching, dressing and finishing lace and other like fabrics, the employment of
elastically connected sections or links carrying tentering hooks, pins or clamps in
which an extension from one end of each section or link extends beyond the adjacent
end of an adjoining section or link and has a spring interposed between such parts
substantially as herein shown and described and for the purpose stated.
