IMPROVEMENTS IN BOBBINS AND SPOOLS
Year: 1875

page_text: LETTERS PATENT to Moses Crabtree, of Ravensthorpe, near Mirfield,
in the County of York, Power Loom Tuner, for the Invention of
"IMPROVEMENTS IN BOBBINS AND SPOOLS."
Sealed the 9th December 1875, and dated the 14th June 1875.
PROVISIONAL SPECIFICATION left by the said Moses Crabtree at the
Office of the Commissioners of Patents, with his Petition, on the
14th June 1875.
I, MOSES CRABTREE, of Ravensthorpe, near Mirfield, in the County
of York, Power Loom Tuner, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN BOBBINS AND SPOOLS," to be as
follows:-
This Invention relates to means or appliances to be employed for the
purpose of securing bobbins and spools upon the spindles of spinning
machinery, and upon the shuttle pegs or pins during the process of
weaving.
or in
Hitherto it has been usual to employ pieces of wire bent double
the form of a loop, and the ends driven into the flange of the bobbin or
spool. These wires are very easily driven into the bobbin' or spool too
far to be of any use, and are equally liable to be withdrawn and lost; in
either case the bobbin is rendered useless for the time.

page_text: My improvements consist in substituting instead of wire small
pieces of metal (such as tin), a portion of the metal being cut away
leaving two points or "prongs" so formed that they can be driven
into the flange of the bobbin or spool a certain distance only, and also
that whilst being driven in the prongs shall spread out so as to render 5
their withdrawal difficult. A hole may be punched through the
remaining portion of metal, or it may be left solid according to the
particular kind of appliance attached to the spindle or shuttle pin on
which it is intended to be placed.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Moses Crabtree in the Great Seal Patent Office
on the 14th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
CRABTREE, of Ravensthorpe, near Mirfield, in the County of York,
Power Loom Tuner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Moses Crabtree, Her special
licence, that I, the said Moses Crabtree, my executors, administrators,
and assigns, or such others as I, the said Moses Crabtree, 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
BOBBINS AND SPOOLS," upon the condition (amongst others) that I, the said
Moses Crabtree, my exccutors 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..

page_text: NOW KNOW YE, that I, the said Moses Crabtree, 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 and accompanying Sheet of Drawings (that is
to say):
This Invention relates to means or appliances to be employed for the
purpose of securing bobbins and spools upon the spindles of spinning
machinery, and upon the shuttle pegs or pins during the process of
weaving.
Hitherto it has been usual to employ-pieces of wire-bent double.or in
the form of a loop, and the ends driven into the flange of the bobbin or
spool. These wires are very easily driven into the bobbin or spool too
far to be of any use, and are equally liable to be withdrawn and lost; in
either case the bobbin is rendered useless for the time.
My improvements consist in substituting, instead of wire small pieces
of metal (such as tin), a portion of the metal being cut away leaving
two points or prongs" so formed that they can be driven into the
flange of the bobbin or spool a certain distance only, and also that
whilst being driven in the prongs shall spread out so as to render their
withdrawal difficult. A hole may be punched through the remaining
portion of metal, or it may be left solid according to the particular kind
of appliance attached to the spindle or shuttle pin on which it is
intended to be placed.
Fig. 1 in the accompanying Sheet of Drawings represents my fastener
when stamped or cut out of a sheet of metal, and Fig. 2 shews the
expansion of the points or prongs after being driven into the bobbin.
Both Figures are enlarged for the sake of clearness.
In witness whereof, I, the said Moses Crabtree, have hereunto set
my hand and seal, this Eleventh day of December, in the
year of our Lord One thousand eight hundred and seventy-
