IMPROVEMENTS IN APPARATUS FOR FINISHING WOVEN FABRICS
Year: 1868

page_text: LETTERS PATENT to William Henderson, of the Firm of Walker,
Henderson; and Company, of Glasgow, in the County of Lanark,
North Britain, Engineers, for the Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said William Henderson at
the Office of the Commissioners of Patents, with his Petition, on
the 11th June 1868.
I, WILLIAM HENDERSON, of the Firm of Walker, Henderson, and
Company, of Glasgow, in the County of Lanark, North Britain,
Engineers, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR FINISHING WOVEN FABRICS," to be as
follows:-
This Invention relates to apparatus for finishing woven fabrics of
the kind in which the fabric is held by its edges upon two endless
chains arranged to carry it through the apparatus; and actuated in some
cases' so as to impart an oscillatory or intermittent movement to the
fabric, whereby what is known as the "elastic finish" is obtained. The

page_text: present improvements relate more particularly to the holding details,
and consist in fixing the improved holders herein-after described directly
down upon the top of the links composing the endless chains. These
links are narrow plates, and they are hinged together according to a
common mode of making such chains. The improved holders comprise
parts which are fixed to the links one on each link, and which are
formed with bars constituting the lower holding jaws, and each fixed part
has jointed to it two movable parts constituting the upper holding jaws.
Each movable jaw is formed with a body which fits in between cheeks
formed for it in the fixed part and a pin passed through the body and
the cheeks forms the joint on which the movable jaw hinges or turns,
such joint being a little below the surface of the lower fixed jaw. Each
movable jaw is made to close with considerable force by a bent blade
spring applied between the bottom of the fixed part and the movable
body which has a shoulder formed on it for the spring to act on in a
suitable manner. The springs are fixed by the same screw bolts that
secure the parts to the chain link. Each movable jaw is formed with
a tail piece projecting horizontally or nearly so backwards from its upper
part, and the jaws are opened when required by depressing these tail
pieces by hand or by the action on them of inclined guiding or cam
surfaces with which they come in contact.
What has been herein-before described as the part fixed to the chain
link may be wholly or partly made in one piece with such link and of
malleable cast iron.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Henderson in the Great Seal Patent Office
on the 10th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENDERSON, of the Firm of Walker, Henderson, and Company, of
Glasgow, in the County of Lanark, North Britain, Engineers, send.
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of June, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-first year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto me, the said William Henderson, Her special licence
that I, the said William Henderson, my executors, administrators, and
assigns, or such others as I, the said William Henderson, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time, and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR FINISHING WOVEN FABRICS," upon the condition (amongst others) that
I, the said William Henderson, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent..
NOW KNOW YE, that I, the said William Henderson, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement in writing, reference being had to the
accompanying Drawings, that is to say:-
My said Invention relates to apparatus for finishing woven fabrics of
the kind in which the fabric is held by its edges upon two endless.chains
arranged to carry it through the apparatus and actuated in some cases
so as to impart an oscillatory or intermittent movement to the fabric,
whereby what is known as the "elastic finish" is obtained. My present
improvements relate more particularly to the holding details, and consist
in fixing the improved holders or clips directly down upon the top of the
links composing the endless chain..
And in order that my said Invention, and the manner of performing
the same, may be properly understood, I have hereunto appended a
Sheet of explanatory Drawings to be herein-after referred to, and
representing two slightly different modifications of my improved clips
adapted to different kinds of chains.
One modification is shown in plan in Figure 1, in front elevation or
edge view in Figure 2, and in transverse section in Figure 3. The
endless chain to which this modification is adapted consists of plates 1,
the ends of which are bent round through short rectangular connecting

page_text: links 2. My improved holders or clips comprise each a part 3, which
is fixed on the link plate 1 and which is formed with a bar 4 con-
stituting the lower holding jaw, and each fixed part has jointed to it two
movable parts 5. constituting the upper holding jaws. Each movable
jaw 5 is formed with a body which fits in between cheeks formed for
it in the fixed part 3, and a pin 6 passed through the body and the
cheeks forms the joint on which the movable jaw hinges or turns, such
joint being a little below the surface of the lower fixed jaw 4. Ench
movable jaw 5 is made to close with considerable force by a bent blade
spring 7 applied between the bottom of the fixed part 3 and the movable
body 5, which has a shoulder 8 formed on it for the spring to act on in
a suitable manner. The springs 7 are fixed by the same screw bolts 9
that secure the part 3 to the plate link 1. Each movable jaw 5 is
formed with a tail piece 10 projecting horizontally or nearly so back-
wards from its upper part, and the jaws. are opened when required for
inserting or withdrawing the selvedges of the fabric by depressing these
tail pieces 10 by hand or by the action on them of inclined guiding or
cam surfaces with which they come in contact. One of the brackets 11
formed with an overhanging inclined guide for this purpose is shown
in Figure 3 as fixed to the frame bar 12, in which is formed the guide
groove for the passage of the endless. chain 1, 2. The part 3 fixed to
the chain link may be wholly or partly made in one piece with such link
and of malleable cast iron. When the chain links are thus made of
malleable cast iron I prefer to make them shorter, so that only one upper
jay 5 is fitted in connection with each link instead of two, as in the
modification herein-before described.
A modification adapted for such malleable cast-iron links 13 is shown
in plan in Figure 4, in elevation, or edge view in Figure 5, and in
transverse section in Figure 6. In this. modification each lower jaw 4
is a strip of brass, fixed on small brackets 14 cast in one piece with the
link 13 and projecting out from the side thereof. The other details are
arranged much as in the first modification, excepting that the tail 12
is made to project upwards instead of horizontally, whilst the closing
spring 7 is fixed thereto and acts in the space between the brackets 14.
The inclined guide 11 for opening the clips is modified in shape to suit
the position of the tails 10.
Having thus particularly described my said Invention, and the manner

page_text: claim as the Invention secured to me by the herein-before in part
recited Letters Patent is, the constructing of holders or clips and the
adapting of the same to the endless chains of apparatus for finishing
woven fabrics, substantially in the improved modes herein described and
delineated.
In witness whereof, I, the said William Henderson, have here-
unto set my hand and seal, this Ninth day of December, in
the year of our Lord One thousand eight hundred and sixty-
