IMPROVEMENTS IN WEAVING CLOTH APPLICABLE ESPECIALLY FOR MAKING PADS FOR MEDICAL AND OTHER PURPOSES
Year: 1884

page_text: I, WILLIAM BRADBURY ROBINSON of Brampton in the County of Derby, Lint,
Cotton, Wool and Bandage Manufacturer do hereby declare the nature of my
Invention for "IMPROVEMENTS IN WEAVING CLOTH APPLICABLE ESPECIALLY
FOR MAKING PADS FOR MEDICAL AND OTHER PURPOSES" to be as follows:-
This Invention has for its object improvements in weaving. cloth applicable
especially for making pads for medical and other purposes.
For medical and other purposes I weave a cloth in sections alternately single and
double from selvage to selvage.. In weaving the sections in which the fabric is
single each shoot of the weft interweaves with the whole of the warp forming
thereby a plain or twilled or other weaving as desired; but in weaving the sections
in which the fabric is double each shoot of the weft interweaves with only half of
the warp; and if as I prefer one shuttle only be employed the first shoot will
interweave with one half of the warp and the next shoot with the other half of the
warp and so on alternately.
I thus produce fabrics with cavities at intervals suitable to conveniently receive
absorbent materials cotton wool and the like, from which medical and surgical pads
are commonly made.
The cloth may also be woven with other double portions adapted to receive
strings for fastening the cloth in place when it is used as a medical or surgical
bandage.
I use in weaving cloth of this nature a loom containing a barrel having pegs
upon it to raise the heddles in the desired order and this I do in the ordinary.
and well known manner except that I use a barrel with two sets of pegs upon it,
one suitable for the single and the other for the double fabric and I pass from one
set of pegs to the other by an endwise movement of the barrel. I obtain this
endwise movement by means of a cam wheel with elevations and depressions upon
it corresponding to the design of the cloth I desire to weave. This can wheel
receives a step by step movement at intervals by any convenient driving gear
connected with the loom. The cam controls a lever by which the peg barrel
receives its endwise movement. Whilst a bowl upon the end of the lever bears
upon one of the elevations of the cam it may be that the single fabric is produced
but when in the step by step movement of the cam it happens that the bowl drops
into one of the depressions of the cam then a double fabric is produced and this
will continue until the cam operates to produce another motion endwise of the peg
barrel.

the following statement :-
This Invention has for its object improvements in weaving cloth applicable

until the cam operates to produce another motion endwise of the peg barrel.
In order that my said Invention may be most fully understood and readily carried
into effect I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a piece of cloth woven in accordance with my Invention.
Figure 2 is an edge view of the same and shews where the cloth is made double to
provide a cavity to receive the absorbent material of the pad and the tapes by which
it is to be held in place.
The fabric may be woven of any width and to any length and it is then cut up
into pieces such as that which the Drawing represents.
T
th four haddles and each receives every fourth

page_text: The parts or bands of the fabric between the lines 1 and 2; 3 and 4; 5 and 6
and 7 and 8 are single whilst the parts or bands between the lines 2 and 3;.4
and 5 and 6 and 7 are double.
.
The warp of the fabric runs in the direction from A to B and the weft at
right angles thereto. I prefer to employ cotton both for the warp and weft of the
fabric.
When weaving the single parts or bands of the fabric at every passage of the
shuttle two heddles are raised whilst two remain down; thus at one passage of the
shuttle the heddles 1 and 3 will be raised; at the next the heddles 2 and 4; then
again 1 and 3 and so on alternately.
When weaving the double parts or bands of the fabric at every passage of the
shuttle the number of heddles raised is either three or one. Thus at the first
passage of the shuttle the heddle numbered 1 alone is raised; at the second passage
the heddles 1. 2. and 3 are raised; at the third passage the heddle 2 is raised alone;
at the fourth passage the heddles 1. 2 and 4 are raised; and then the operations
are repeated and for the next passage of the shuttle heddle 1 is raised.
The working of the heddles may be reversed and other changes may be made
in the order in which the heddles are raised but I prefer the method described
above.
Thus a fabric such as is represented in the Drawing is produced. The cotton
wool or other absorbent material is introduced at the part or band between the
lines 4 and 5 upon the Drawing and the tapes to hold the pad in place are inserted
at the parts or bands between the lines 2 and 3 and 6 and 7.
The pads thus manufactured are useful for many medical and surgical uses and
also especially for catamenial purposes.
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 :-Weaving cloth in alternate bands single and double as herein described
thereby producing a fabric applicable especially for making pads for medical and
other purposes.
