Sealed the 21st February 1865, and dated the 27th August 1864.
PROVISIONAL SPECIFICATION left by the said Edmund Calvert and
Thomas Edmeston at the Office of the Commissioners of Patents, with
their Petition, on the 27th August 1864.
We, EDMUND CALVERT, of Walton-le-Dale, in the County of Lancaster,
and THOMAS EDMESTON, of the same Place, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN PARTS OF MACHINERY OR APPARATUS
EMPLOYED IN PREPARING, SPINNING, AND DOUBLING FIBROUS MATERIALS, AND IN
THE APPARATUS FOR MANUFACTURING THE SAID PARTS," to be as follows:-
This Invention relates to those descriptions of machinery in which bobbins
or tubes are employed, and consists in placing a plate or platform on the top
of the washer wheel, or bobbin braid used for driving the bobbins or tubes.

page_text: The aforesaid plate or platform is made of cast or sheet metal, or other suitable
material, in the form of a washer, having on its outer edge one or more pro-
jections, which are fitted into recesses on the outer edge of the washer wheel
or bobbin braid, so that both revolve together. There are also one or more
raised parts or projections on the top of the plate or platform for the purpose
of fitting into a corresponding slit or slits in the end of the bobbins or tubes.
We prefer the plate or platform to be made of sheet steel, and form the raised
parts by punching square holes in the plate with a punch having only three
cutting sides, and leaving the burr on the fourth side of each hole to form the
projection; but the punch may be made of other forms than that described,
so long as a burr is retained to form the raised part or projection for causing
the bobbin or tube to revolve. The plates may be made in any suitable
punching machine having the aforesaid punches attached to it. When the
plates or platforms are cast or moulded all the projections are formed on them
at the same time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edmund Calvert and Thomas Edmeston in the Great Seal
Patent Office on the 25th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDMUND
CALVERT, of Walton-le-Dale, in the County of Lancaster, and THOMAS.
EDMESTON, of the same Place, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of August, in the year of our Lord,
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Edmund Calvert and Thomas Edmeston, Her special license that we, the
said Edmund Calvert and Thomas Edmeston, our executors, administrators, and
assigns, or such others as we, the said Edmund Calvert and Thomas Edmes-
ton, 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 PARTS OF MACHINERY OR
APPARATUS EMPLOYED IN PREPARING, SPINNING, AND DOUBLING FIBROUS MATERIALS,

page_text: AND IN THE APPARATUS FOR MANUFACTURING THE SAID PARTS," upon the condition
(amongst others) that we, the said Edmund Calvert and Thomas Edmeston;
our executors or administrators, by an instrument in writing under our, or
their, or one of our or 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.
NOW KNOW YE, that we, the said Edmund Calvert and Thomas
Edmeston, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer--
tained in and by the following statement (that is to say):-
This Invention relates to those descriptions of machinery in which bobbins
or tubes are employed, and consists in placing a plate or platform on the top
of a chamber or recess formed in the top of the washer wheel or. bobbin
braid used for driving the bobbins or tubes. The aforesaid plate or platformı
is made of cast or sheet metal, or other suitable material, in the form of a
washer, baving on its outer edge one or more projections, which are fitted into
recesses on the outer edge of the washer wheel or bobbin braid, so that both
revolve together. There are also one or more raised parts or projections on
the top of the plate or platform for the purpose of fitting into a corresponding
slit or slits in the ends of the bobbins or tubes, and causing them to revolve.
We prefer the plate or platform to be made of sheet steel, and form the raised
parts by punching square holes in the plate with a square punch having only
three cutting edges, the fourth edge being rounded or inclined for leaving the
burr on that side of each hole to form the raised part, or the punch may be
triangular, with two cutting edges, and one rounded or inclined edge for
making triangular raised parts, or the punch may be circular on one side,
and have three flat sides with one rounded or inclined edge for leaving the
burr and forming the raised part, or the punch may be made of other forms
than those described, provided each punch has one rounded or inclined edge
for forming the raised part or projection for causing the bobbin or tube to
revolve, and the plates may be made in any suitable punching machine having
the aforesaid punches attached to it. . When the plates or platforms are cast
or moulded all the projections are formed on them at the same time. By
means of the aforesaid plate ог platform placed at the top of a recess in the
top of the washer wheel or bobbin braid we obtain a closed chamber for
holding flannel or other fibrous materials, which when saturated with oil or

page_text: other lubricating matter will lubricate the. spindle and washer wheel very
efficiently, and at the same time loose fibres and dust will be prevented from
being mixed with the oil, and the bottoms of the bobbins prevented from
becoming oiled and dirty. The plates and platforms are simple in construc
tion, and besides being more durable in use and cheaper in manufacture than
the rivetted tabs hitherto used, they are free from the defect of the possibility
of the lubricating matter escaping at the rivet hole of the tab; and as the
plate or platform has one, two, or more raised parts or projections fitting into
corresponding slits in the. bobbins, the said bobbins can be driven without
contact with the spindles, and much steadier when there are two or more
raised parts than by the before-mentioned ordinary tabs.
These improvements will be clearly understood by referring to the figures
and letters on the accompanying Sheet of Drawings, in which Figure 1 is an
elevation with part in section shewing the application of one of our improved.
plates or platforms to one of the washer wheels or bobbin braids used in
machinery for, preparing, spinning, and doubling fibrous materials; Figure 2,
a plan of the washer or bobbin braid, with the plate or platform removed;
and Figure 3, a plan of the plate or platform detached:
The washer wheel or bobbin braid is marked a; it has at the top a circular
chamber or recess. b, having its edge formed as a circular ledge c, in the edge
of which there are recesses d, Figure 2. The plate or platform is marked e;
it has at its outer edge projections f, Figure 3, and at the top raised parts or
projections g, Figs. 1 and 3. The circular edge of the plate rests in the
ledge c and the projections f in the recesses d, so that the plate is held to and
turns with the wheel, and at the same time forms a lid or cover to the
chamber b, the projections 9 being fitted into slits in the ends of the bobbins'
or tubes. It will be readily seen that flannel or other fibrous material can be
placed in the chamber and saturated with oil for lubricating the spindle and
washer wheel, and that the plate or platform covers the chamber and prevents.
fibres and dust from becoming mixed with the oil, and the bobbins or tubes
from becoming oily and dirty, and also that the projections or drivers on the
top of the plate can turn the bobbins or tubes with steadiness.
The apparatus for manufacturing the improved plates or platforms of sheet
metal is as follows: -In an ordinary screw lever or eccentric punching.
machine we fix a die having a circular hole in the centre corresponding in
size with the hole required in the plate or platform, and also one or more
rectangular or other shaped holes corresponding in shape with the raised parts
required on the top of the plate. or platform. In the ram or slide of the

page_text: punching machine we fix a puncb, the centre or nipple of which corresponds
in size and form with the hole in the centre of the die before mentioned. The
upper part of the punch is of sufficient diameter or size to admit of fitting
into it one or more small punches corresponding with the rectangular or other
shaped hole or holes in the die. If it is required to make the raised parts on
the plate or platform square, the bottom of each of the small punches must
also be square, with only three cutting sides, the fourth side being rounded or
inclined, in order that the punch shall not cut the metal on that side, but
bend it over as a burr, and raise it to a perpendicular position as the punch
proceeds downwards, and thereby form one of the raised parts or projections
on the top of the plate; other forms of raised parts can be made by
forming the dies and constructing the small punches of the shapes required,
and the first operation consists in punching the central hole, and forming one
or more raised parts during one downward movement of the ram or slide of
the punching machine. For the next or second operation we fix in the
punching machine a die having in it a hole corresponding with the required
forin and size of the external circular edge of the plate or platform, and also
having slots or grooves cut into the outer circumference of the hole in the die
to form the projections required to fit the recesses in the edge of the washer
wheel. In the ram or slide of the machine we fix a punch, which fits the
hole in the die, and has at its bottom end a nipple or projecting part-fitting
the central hole formed in the first operation, and having through it a slot or
hole for holding cross punches or cutters corresponding with the slots or
grooves in the outer circumference of the hole in the die, and the punches
and dies for the first and second operations can be made from solid steel, or
in parts fitted together. For performing the second operation it is only
necessary to place the central hole punched in the first operation upon the
nipple of the second punch, so that as the ram or slide descends the punches
and dies will shape the external edge of the plate or platform and complete
its manufacture.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we do not claim the punching machines for holding the dies
and punches, as they are old and in ordinary use; but what we claim is, the
application to the tops of the washer wheels or bobbin braids of metal plates
or platforms having projections on their outer edges, and raised parts or pro-
jections on their tops; and also the dies and punches for forming the said plates
or platforms with their raised parts or projections, as all such improvements

page_text: are herein described and illustrated in the accompanying Sheet of Drawings,
or any mere modification thereof.
In witness whereof; I, the said Edmund Calvert, for and on behalf of
myself and the said Thomas. Edmeston, have hereunto set my hand
and seal, this Twenty-first day of February, in the year of our Lord
One-thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
