I LEONARD LINDLEY of Sherwood Street in the Town and County of the Town
of Nottingham, Lace Dresser, do hereby declare the nature of said Invention for
IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN STRETCHING, DRESSING,
AND FINISHING LACE AND OTHER LIKE FABRICS to be as follows:-
The present invention relates to improvements upon a former invention for
which I obtained provisional protection dated September 13. 1884 No 12375.
In my former provisional specification I described the employment of separate
or disconnected, or lightly connected sections carrying the tentering hooks, pins or
clamps in order to afford facility for stretching the fabric in the direction of its
length.
When using separate disconnected or lightly connected sections carrying tentering
hooks, pins, or clamps there was nothing but the fabric under treatment to ensure
the said sections in the stretching operation extending to equal distances from each
other.
Now according to my present Invention I secure the regular extension of the
sections carrying the tentering hooks, pins or clamps by connecting said sections
together by intermediate links, which whilst freely permitting the separation or
extension of the said sections from each other, at the same time ensure that the
distances to which such sections are separated from each other shall be perfectly
uniform.
The method in which I prefer to carry my present invention into effect is as
follows: To the centre of the front edge of each section I connect a dependent link
which is capable of moving freely upon its connecting means; these dependent
links are according to one plan made of gradually increased length, each of such
links having the same increase of length as compared to the next adjoining shorter
link. These dependent links are connected at their lower ends at equal distances
to a rod or bar in such manner as to be capable of freely moving upon such
connecting means.
The above mentioned rod or bar consequent upon the gradual increase of length
of the dependent links assumes an inclined position; this necessitates the employ-
ment in long tentering frames of a number of such inclined rods or bars and their
connected links; these are pin jointed together to form a series to the desired

page_text: length. In some cases I employ checks or springs to limit the extension of the
sections carrying the tentering hooks.
Instead however of making the dependent links of different lengths and
connecting them at their lower ends to a rod or bar as above described such
dependent links may be made all of the same length in which case I connect two
of such links to the centre of each section carrying the tentering hooks, pins or
clamps and I cause such links to cross each other in pairs and to be pin jointed
together at the centre of their length and at their lower ends in a similar manner
to the pin-jointed links of lazy tongs. Suitable stops may be employed to prevent
the undue extension of the parts.
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 the
travelling bars described in my former provisional specification; I also fix the
section of tentering hooks, pins or clamps, adjacent to the first mentioned cross bar,
to the fixed longitudinal bar whilst I fix the section 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.
I preferably form the sections carrying the tentering hooks, pins or clamps with
alternate projecting and hollow Vends so that adjacent sections may fit into each
other and thereby assist in retaining such sections, when close together, in a
straight line.

improvements in machinery or Apparatus Employed in Stretching,
Dressing, and Finishing Lace and other like Fabrics.
I LEONARD LINDLEY of Sherwood Street in the Town and County of the Town
of Nottingham, Lace Dresser, do hereby declare the nature of said invention and
in what manner the same is to be performed to be particularly described and
ascertained in by the following statement :-
The present invention relates to improvements upon a former invention for
which I obtained Letters Patent dated September 13, 1884 N° 12375.
In the specification of my said Patent I described the employment of separate or
disconnected, or lightly connected sections carrying the tentering hooks, pins or
clamps in order to afford facility for stretching the fabric in the direction of its
length. When using separate disconnected or lightly connected sections carrying
tentering hooks, pins or clamps there was nothing but the fabric under treatment
to ensure the said sections in the stretching operation extending to equal distances.
from each other.
Now according to my present invention I secure the regular extension of the
sections carrying the tentering hooks, pins or clamps by connecting said sections
together by intermediate links, which whilst freely permitting the separation or
extension of the said sections from each other, at the same time ensure that the
distances to which such sections are separated from each other shall be perfectly
uniform.
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 longitudinal elevation of parts of one side of a tentering frame
Figure 2 is a plan and Figure 3 is a cross section of the same showing one method
in which I carry my invention into effect and Figure 4 is a longitudinal elevation
of parts showing another method of carrying my invention into effect.
In all the figures like parts are marked with similar letters of reference.
The method in which I prefer to carry my present invention into effect is as
follows:
To the centre of the front edge of each section a carrying the tentering hooks
I connect a dependent link b which is capable of moving freely upon its connecting
means; these dependent links b are according to one plan made of gradually
increased length each of such links b having the same increase of length as com-
pared to the next adjoining shorter link.
These dependent links bare connected at their lower ends at equal distances to a
rod or bar c in such manner as to be capable of freely moving upon such connecting
means.
The above mentioned rod or bar c consequent upon the gradual increase of
length of the dependent links b assumes an inclined position, this necessitates the
employment in long tentering frames of a number of such inclined rods or bars c
and their connected links b, these rods or bars c are pin-jointed at one end to the
lower part of the longest link b of a series, and at the other end to the centre b¹ of
a link b, or in the case of the end series to the fixed arm j in order to form a series

page_text: to the desired length. In some cases I employ checks or springs & connected at
one end to the section a to which one of the longest links b is connected and at the
other end to the middle of the longest link b of the next series or to the end of
the shortest link b of the end series, in order to limit the extension of the sections a
carrying the tentering hooks.
Instead however of making the dependent links 6 of different lengths and
connecting them at their lower ends to a rod or bar c as above described with
respect to Figures 1, 2, 3, such dependent links b may be made all of the same
length as shown at Figure 4 in which case I connect two of such links b to the
centre of each section a carrying the tentering hooks, pins or clamps and I cause
Buch links b to cross each other in pairs and to be pin-jointed together at the
centre of their length and at their lower ends in a similar manner to the pin-jointed
links of lazy-tongs.
Suitable stops checks or springs may be employed to prevent the undue extension
of the parts.
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 a carrying the
same are close together, the ends of the fabric, are attached to cross bars de the
cross bar d of which is fixed to stationary longitudinal bars f whilst the other
bar e is fixed to travelling bars g, operated by screws h.
I also fix the section a of tentering hooks pins or clamps, adjacent to the first
mentioned cross bar d. to the fixed longitudinal bar f by links or other suitable
means whilst I fix the section a at the further end of the fabric to the travelling
cross bar e. Then by giving motion to the moveable cross bar the fabric will be
equally stretched throughout its entire length.
In order further to regulate the motion of the sections a I connect cords i to
fixed arms and carry them round pulleys a¹ mounted on the first section a and
around other pulleys a¹ at equal distances along the series and finally over a
pulley where it is attached to a weight l.
I preferably form the sections a carrying the tentering hooks, pins or clamps
with alternate projecting and hollow V ends a² a³ so that adjacent sections may fit
into each other and thereby assist in retaining such sections, when close together
in a straight line.
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
I. In machinery or apparatus employed in stretching, dressing and finishing
lace and other like fabrics and operating in the manner herein described connecting
