IMPROVEMENTS IN SHUTTLE TIPS
Year: 1873

page_text: LETTERS PATENT to Joseph Holding and William Randall Harris,
both of Manchester, in the County of Lancaster, Machinists, for
the Invention of "IMPROVEMENTS IN SHUTTLE TIPS."
PROVISIONAL SPECIFICATION left by the said Joseph Holding and
William Randall Harris at the Office of the Commissioners of
Patents, with their Petition, on the 5th February 1873.
WC, JOSEPH HOLDING and WILLIAM RANDALL HARRIS, both of
Manchester, in the County of Lancaster, Machinists, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN SHUTTLE TIPS,"
to be as follows:-
Our Invention relates to the metal tips or points which are fixed in
the ends of shuttles employed in looms for weaving, and has for its
object to so modify the ordinary form of such tips as that the pickers
employed in the propelling of the said shutles shall not be so rapidly
deteriorated by striking the said tips as at present. As hitherto formed,

page_text: cach tip has been in the form of a cone projecting from the end of the
shuttle.
When forming the said tips in manner according with our said Inven-
tion we form a shoulder upon cach tip a short distance from the point of
the said tip. We prefer to make the said shoulder of a rounded form, and 5
to make the point of the tip of a sharper or more acuto conical form
than is usual, but these details may be varied as found to be most
suitable.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Holding and William Randall Harris in 1
the Great Seal Patent Office on the 2nd August 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
HOLDING and WILLIAM RANDALL HARRIS, both of Manchester, in the
County of Lancaster, Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 1
Letters Patent, bearing date the Fifth day of February, in the year
of our Lord One thousand cight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Joseph Holding and William
Randall Harris, Her special license that we, the said Joseph Holding 2
and William Randall Harris, our executors, administrators, and assigns,
or such others as we, the said Joseph Holding and William Randall
Harris, our executors, administrators, and assigns, should at any time
agreo with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, 2
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 SHUTTLE TIPS," upon the condition, amongst others,
that we, the said Joseph Holding and William Randall Harris, by an
instrument in writing under our hands and scals, should particularly 3
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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that we, the said Joseph Holding and William
Randall Harris, do hereby declare the nature of our 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 accom-
panying Drawings, that is to say :—
Our Invention relates to the metal tips or points which are fixed in
the ends of shuttles employed in looms for weaving, and has for its
object to so modify the ordinary form of such tips as that the pickers
employed in the propelling of the said shuttles shall not be so rapidly
deteriorated by striking the said tips as at present. As hitherto formed
each tip has been in the form of a cone projecting from the end of the
shuttle.
When forming the said tips in manner according with our said
Invention we form a shoulder upon cach tip a short distance from the
point of the said tip. We profer to make the said shoulder of a rounded
form, and to make the point of the tip of a sharper or more acute
conical form than is usual, but these details may be varied as found to
most suitable.
And in order that our said Invention may be fully understood we will
now refer to the accompanying Sheet of Drawings, wherein Fig. 1
represents an ordinary shuttle tip, and Fig. 2 a shuttle tip made in
accordance with our Invention.
Figs. 3 and 4 illustrate the comparative destructive effect of each tip
upon a picker.
In Fig. 3, a represents the end of a shuttle, and a picker. The point
of the tip c is represented as having penetrated to the heart of the
picker; this penetration being effected in practice in a comparatively
short time by reason of the wedge-like action of the tip and the con-
tinued action of the parts results in the splitting and consequent
uselessness of the picker for its intended purpose.
In Fig. 4 the point of the tip is represented as having penetrated only
as far as the shoulder d, the said shoulder then preventing or retarding
further penetration, and thus rendering the picker more durable.
Having now fully described and indicated the nature of our said In-
vention, we would in conclusion have it to be distinctly understood that
we claim the manufacture and use of shuttle tips made in the form

page_text: substantially as herein-before described and as illustrated in the accom-
panying Drawings.
In witness whercof, we, the said Joseph Holding and William
Randall Harris, have hereunto set our hands and scals, this
First day of August, in the year of our Lord One thousand eight
hundred and seventy-three.
