Year: 1872

page_text: LETTERS PATENT to Frederick Burgess, Wool Comber and Worsted
Spinner, and Joseph Robertshaw, Mill Overlooker, both of Bradford,
in the County of York, for the Invention of "IMPROVEMENTS IN
Sealed the 27th May.1873, and dated the 28th November 1872.
PROVISIONAL SPECIFICATION left by the said Frederick Burgess and
Joseph Robertshaw at the Office of the Commissioners of Patents,
with their Petition, on the 28th November 1$72.
We, FREDERICK BURGESS, Wool Comber and Worsted Spinner, and
JOSEPH ROBERTSHAW, Mill Overlooker, both of Bradford, in the County
of York, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY FOR SPINNING AND TWISTING FIBRES," to be as
follows:-
This Invention relates to the spindles and flyers of such machinery;
and has for its object the construction of spindles capable of being run
1

page_text: In constructing spindles according to this our Invention we employ a
fixed or non-revolving spindle on which we slide a tube (by preference
of brass), to the lower end or foot of which we secure the driving pully
or warl, the collar of which rests and revolves on an enlarged portion of
the spindle. The top part of the said tube is squared on two of its sides,
so as to receive and hold securely the flyer. The top of the fixed spindle
is screwed or chased, and projects slightly above the top of the flyer so
as to receive a weight which is screwed on the top of the said spindle
for the purpose of steadying its motion, and resting on the driving pully
or warl is a washer or disc of leather having an annular ring of leather
thereon, within which the flange of the bobbin is received.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Burgess and Joseph Robertshaw in
the Great Seal Patent Office on the 27th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
BURGESS, Wool Comber and Worsted Spinner, and JOSEPH ROBERTSHAW,
Mill Overlooker, both of Bradford, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of November, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Frederick Burgess and Joseph Robertshaw,
Her special licence that we, the said Frederick Burgess and Joseph
Robertshaw, our executors, administrators, and assigns, or such
others as we, the said Frederick Burgess and Joseph Robertshaw,
our 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 MACHINERY FOR SPINNING AND TWISTING FIBRES," upon
the condition (amongst others) that we, the said Frederick Burgess and
Joseph Robertshaw, our executors or administrators, by an instrument
in writing under our, or their, or one of their hands and seals, should-

page_text: 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 we, the said Frederick Burgess and Joseph
Robertshaw, do hereby declare the nature of our said Invention,
and in what manner the same was to be performed, to be particularly
described and ascertained in and by the following statement and
accompanying Sheet of Drawings, that is to say :—
This Invention relates to the spindles and flyers of such machinery,
and has for its object the construction of spindles capable of being run at
high speed.
In constructing spindles according to this our Invention we employ a
fixed or non-revolving spindle on which we slide a tube (by preference
of brass), to the lower end or foot of which we secure the driving pulley
or "wharle," the collar of which rests and revolves on an enlarged portion
of the spindle. The top part of the said tube is squared on two of its
sides, so as to receive and hold securely the flyer. The top of the fixed
spindle is screwed or chased, and projects slightly above the top of the
flyer, so as to receive a weight which is screwed on the top of the said
spindle for the purpose of steadying its motion, and resting on the
driving pulley or "wharle" is a washer or disc of leather having an
annular ring of leather thereon, within which the flange of the bobbin is
received.
In order that the Invention may be clearly understood we have here-
unto annexed a Sheet of Drawings, in which Fig. 1 is an elevation of a
spindle and flyer constructed according to this our Invention, and Fig. 2
is a sectional elevation of the same.
A is a fixed or non-revolving spindle on which we slide a tube B (by
preference of brass), to the lower end or foot of which we secure the
driving pulley or "wharl" C, the collar D of which rests and revolves
on an enlarged portion E of the spindle A. The top part of the tube B
is squared on two of its sides, so as to receive and hold securely.the
flyer F. The top of the fixed spindle A is screwed or chased, and pro-
jects slightly above the top of the flyer F, so as to receive a weight H
which is screwed on the top of the said spindle for the purpose of

page_text: steadying its motion, and resting on the driving pulley or "wharl" C is
a washer or disc of leather J having an annular ring of leather K thereon,
within which the flange of the bobbin is received.
Having thus fully described the nature and particulars of this our said
Invention, we wish it to be understood that apart from the construction
of apparatus as and for the purpose herein described we lay no claim to
the use of the stationary or non-rotatory spindle, nor the tube thereon.
In witness whereof, I, the said Frederick Burgess, for and on
behalf of myself and the said Joseph Robertshaw, have hereunto
set my band and seal, this Twenty-sixth day of May, in the year
of our Lord One thousand eight hundred and seventy-three.
Witness,
FREDERICK BURGESS.
