IMPROVEMENTS IN MEASURING TAPES
Year: 1880

page_text: LETTERS PATENT to William Chesterman, of Bow Works, Sheffield, in the
County of York, Measuring Tape Manufacturer, for an Invention of
"IMPROVEMENTS IN MEASURING TAPES."
PROVISIONAL SPECIFICATION left by the said William Chesterman at the
Office of the Commissioners of Patents on the 11th February 1880.
WILLIAM CHESTERMAN, of Bow Works, Sheffield, in the County of York,
Measuring Tape Manufacturer. "IMPROVEMENTS IN MEASURING TAPES."
This Invention relates to improvements in measuring tapes that are made from
woven materials, that is, fibrous materials interwoven with each other, and consists
in weaving the warp and weft threads together in such a manner that the warp
threads shall lie alternately over and under one weft thread, and the weft thread
shall lie alternately over and under two or more warp threads.
The arrangement of the threads may, it is evident, be that the warp threads are
all double in the leash, except one, two, or more, which are single; the weft in this
case could be arranged to go over and under the single warp thread.
I however prefer the arrangement of weaving first described.

the said William Chesterman in the Great Seal Patent Office on the 10th August
1880.
WILLIAM CHESTERMAN, of Bow Works, Sheffield, in the County of York,
Measuring Tape Manufacturer. "IMPROVEMENTS IN MEASURING TAPES."
The object of this Invention is the production of measuring tapes of an improved
character made froin woven materials, that is, fibrous materials interwoven with
each other, and the Invention consists in the employment of a tape in which the
warp and weft threads are interwoven, so that each warp thread will lie alternately
over and under one weft thread, whereas the weft thread will lie alternately over
and under two or more warp threads. I prefer that each weft thread, or, speaking
technically, that each shot of the weft, should lie alternately over and under two
warp threads, but I do not confine myself to this arrangement, as for some purposes
it would be more convenient that it should lie alternately over three and under
three, or any other similar arrangement in accordance with this Invention. It is
evident that the above arrangement might be varied by the introduction of one or
more warp threads lying single instead of double or treble, as above described, but
I prefer the whole of the warp to lie double.
In carrying out my Invention it will not necessitate any alteration in the loom
itself, but will only require that the warps shall be so arranged in the loom that
the threads or yarn shall lie two or more in the leash.
Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed or put in practice, I
hereby declare that I claim the Invention of "Improvements in Mensuring Tapes,"
wherein the essential point or feature is that each warp thread shall lie alternately
over and under one weft thread, while each weft thread shall lie alternately over
and under two or more warp threads.
In witness whereof, I, the said William Chesterman, have hereunto set my
hand and seal, this Seventh day of August, in the year of our Lord One
thousand eight hundred and eighty.
WILLIAM CHESTERMAN. (L.S.)
