PROVISIONAL SPECIFICATION.
Improvements relating to the Means and Method Employed in the
Manufacture of Elastic Webbing.
We, JOSEPH BURGESS, and HARRY EDWARD BURGESS of Birstall Street,
Leicester, trading as J. Burgess & Son, Elastic Web Manufacturers, do hereby
declare the nature of this invention to be as follows:-
Our invention is devised with a view to ensure the production of an improved
elastic webbing, such for instance as is used for boots and shoes.
In accordance with our improvements, the harness shafts of the loom are three
(only) in number; and which, to facilitate description we will designate shafts 1,
2 and 3 respectively. In addition to these three harness shafts we employ one
rubber shaft and two edge wire shafts. We also employ only three cams and three
levers.
When the loom is at work the weaving motion of the harness shafts is as
follows:-When shaft 1 is at the bottom, the bottom, shuttle goes over it one
shute, the shaft then rises to the top and both shuttles go under it once; it then
moves to the centre and remains there while the bottom shuttle goes under and the
top shuttle over once each. The shaft then falls to the bottom and the bottom
shuttle goes over it once, and thereafter returns to the top and both shuttles go
under it once. Shafts 2 and 3 repeat the above operations.
By the mode of working which we adopt as above described each shaft is changed
at every shute and it forms a feature distinctive of our improvements that by
means thereof we are enabled to ensure that a perfect twill is made at top, bottom
and centre.
The improved elastic webbing in accordance with our invention may be produced
in silk, cotton, wool, or any other similar material or materials.

COMPLETE SPECIFICATION.
Improvements relating to the Means and Method Employed in the
Manufacture of Elastic Webbing.
We, JOSEPH BURGESS, and HARRY EDWARD BURGESS, of Birstall Street,
Leicester, trading as J. Burgess & Son, Elastic Web Manufacturers, 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:-
This invention relates to improvements in the manufacture of elastic webbing
suitable for boots and shoes and in accordance therewith we obtain a perfect twill
at top, bottom and centre. The webbing may be made in silk, cotton, wool or any
other suitable material. In making the webbing according to our invention we use
three harness shafts only and every shaft is changed at every shute and three cams
and three levers only are consequently required to be used for operating the
same.

page_text: And in order that this our invention may be fully understood reference is had to
the accompanying sheet of drawings in which
Figure 1 represents, in vertical sectional elevation, such part of a loom as will
illustrate the said invention and the manner in which the same is to be performed.
The section is taken as the shuttles are going by the front sley, and passing through
the binder shafts.
Figure 2 represents in further illustration of the foregoing, what is known as a
weavers diagram.
A's aforesaid we employ three harness shafts only and these are lettered a 6 and c
upon the drawing. d is the rubber shaft; and e and fare the edge wire shafts.
The three cams before referred to we distinguish by the letter g, their corresponding
levers being marked g'. These latter are pivotted at 92 to the standard 7. i is the
top shuttle, k the bottom shuttle, I the rubber beam, and m is the front sley.
In the process of weaving in accordance with this invention the motion of the
shafts a band cis as follows:-
When the shaft a is at the bottom (in which position it is shewn in the drawing)
the bottom shuttle goes over it one shute, this shaft a then rises to the top and both
shuttles ik go under it once; it then moves to the centre, and remains while the bottom
shuttle goes under and the top shuttle i over once each; it then falls to the
bottom and the bottom shuttle-k goes over it once; it then comes again to the top
and both shuttles go under it once. The shafts being operated simultaneously, the
above described functions are then repeated, respectively, with shafts b and c, and
80 on.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. The improvements relating to the means and method employed in the manu-
facture of elastic webbing substantially as herein described and shewn in the
accompanying drawing.
2. In the manufacture of elastic webbing the employment of the three harness
shafts a b c operated from the three cams g and levers g' all arranged and acting in
combination with the two shuttles ik, substantially as and for the purposes
hereinbefore set forth and illustrated.
