Year: 1874

page_text: LETTERS PATENT to George Haseltine, of the "International Patent
Office," Southampton Buildings, London, Doctor of Laws, for the
Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF WEAVERS' OR
WARPERS' SPOOLS."-A communication from abroad by Hezekiahı
Hazard Bryant, of Boston, and David Nichols, of Lowell, both in
Massachusetts, United States of America.
Scaled the 11th December 1874, and dated the 22nd October 1874.
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 22nd October 1874, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Buildings,
London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN THE CONSTRUCTION OF WEAVERS' OR WARPERS' SPOOLS," and have petitioned
Her Majesty to grant unto me, my executors, administrators, and

page_text: assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that it has been communicated to me from abroad
by Hezekiah Hazard Bryant, of Boston, and David Nichols, of Lowell,
both in Massachusetts, United States of America.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and scal,
fully describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawings forming
part of this Specification, and in which Figure 1 is a longitudinal section 1
of a spool constructed according to this Invention; Figure 2 is an end
elevation of the head of the spool and the plug bolt securing it to the
barrel; and Figure 3 is a sectional view showing the head of the plug
bolt as sheathed with metal.
B denotes the barrel; A, the chamber of the barrel; C, a plug 1
bolt which secures the head to the barrel; and D, the heads of the
spool.
-
A practical method for making this spool may be described as
follows I take a disc of metal of the proper size to make a spool.
head of the required diameter, punch a circular hole at its centre a
of the same diameter as that of the chamber A, and then proceed
by means of a suitable screw or drop piece to turn the flange a around
the outer edge of the disc, as shown in Figure 1, at the same time
forming the radial corrugations c on the body of the disc, as shown
in Figure 2, the said corrugations c terminating somewhat inside of
the periphery of the head or disc D after the flange a is turned on it,
so as to leave said periphery true and flush at all points with the
spaces intervening between the corrugations c for the purpose of pre-
venting the catching and breaking of the thread or yarn wound upon
the spool in these corrugations, as would be the case if said corrugations
protruded through said periphery when the spool is used in speeders,
or mule, or spinning frames.
The flange a and corrugations c, substantially as shown and specified,
serve the several purposes of stiffening the metal, giving a flat or
rounded edge to the disc, and providing one side of said disc with
a straight and true surface or surfaces against which the thread can
uniformly pack as it is wound upon the spool.

page_text: The fact that the thread is carried to and fro across the spool by
machinery just so far cach time, explains the necessity of making
the corrugations c radial instead of concentric, otherwise it would be
impossible to properly pack the thread upon the spool.
I do not wish to confine this Invention to the use of the flange a.
The barrel of the spool is turned in the ordinary manner from wood,
and of any required diameter or size of chamber.
The plug bolt C has its tongue turned to the same diameter as that
of the chamber A provided for the barrel B. This tongue properly
pierced to receive a spindle or skewer is made about three quarters
of an inch in length, and is provided with a head (shewn at d in
Figure 1) of a diameter about the same as that of the barrel B.
The disc D, barrel B, and plug bolt C having been made substantially
as shown and specified, are joined together as a spool by applying gluc
to the tongue of the plug bolt, and passing it through the orifice
provided at the centre of the disc into the chamber of the barrel.
It is obvious that the plug bolt C is not confined to the spool of
the said Invention, it being equally serviceable in spools of various
constructions.
In Figure 3 the outer end or part of the plug bolt C is shown
sheathed with metal for protecting the wood against injury in the
use of the spool. This metal sheathing is in the form of a cap
covering the end ƒ of the bolt C, and it is fixed or secured in place by
setting in its edge 7, as shewn in the Drawing.
In lieu of capping the end of the plug with metal, as above specified,
it may be left uncovered, and only the periphery of the bolt sheathed,
as a tire is applied to a wheel.
Having thus fully described the said Invention as communicated to
me by my foreign correspondents, and the manner of performing the
samc, I wish it understood that I claim,—
First. A metal head provided with the radial corrugations c, sub-
stantially as above set forth.
Second. The combination of the corrugations c and the flange a, as
above set forth.

page_text: Fourth. A spool or wood provided with metal corrugated mangen
heads held in position by plug bolts, as above set forth.
Fifth. The metal sheathing applied to the plug C, as above set forth
and for the purpose specified.
In witness whereof, I, the said George Haseltine, have hereunto
set my hand and scal, this Twenty-second day of October,
in the year of our Lord One thousand eight hundred and seventy-
four
