IMPROVEMENTS IN THE MANUFACTURE PROVISIONAL SPECIFICATION
Year: 1874

page_text: LETTERS PATENT to William Corder, of the Firm of Corder and
Turley, of Birmingham, in the County of Warwick, Umbrella and
Parasol Manufacturers, and Edward Shore, of Birmingham aforesaid,
Tool Maker, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
PROVISIONAL SPECIFICATION left by the said William Corder and
Edward Shore at the Office of the Commissioners of Patents, with
their Petition, on the 3rd June 1874.
We, WILLIAM CORDER, of the Firm of Corder and Turley, of
Birmingham, in the County of Warwick, Umbrella and Parasol Manu-
facturers, and EDWARD SHORE, of Birmingham aforesaid, Tool Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF RUNNERS AND TOP NOTCHES FOR UMBRELLAS AND
PARASOLS," to be as follows:-
Our Invention has reference principally to that part of the said
runners and top notches called the notch, and our Invention consists

page_text: mainly of the improvements hercin-after described in making the said
notch.
According to our Invention we make the notch from three rings of
iron or other metal, placed face to face, the outer rings being of greater
diameter and thinner than the middle ring.
When the three rings are combined together a grooved ring is thereby
formed, the outer edge of the middle ring of the compound ring con-
stituting the bottom of the groove in the said compound ring. In order
to convert this grooved ring into a notch nicks are made across it
radially. These nicks may be made before or after the rings have been
connected to the barrel of the runner or top notch.
When the nicks are made in the rings before the said rings are con-
nected to the barrel the said nicks are pierced or cut out by dies, and
tools worked in a press.
We connect the rings to the end of the barrel of the runner or top:
notch by brazing them thereto. The end of the barrel is slightly tapered,
and the rings are placed thereon; the edge of the barrel is then turned
into a flange to retain the rings in position during brazing.
When plain or unnotched rings have been brazed to the barrel the
nicks are made in them in the usual manner. After the notch has been
completed the flange on the barrel is removed by turning in a lathe, and
the runner or top notch is finished in the usual way; or the rings may
be brazed to the barrel in the following manner :-The outer rings are
mado as already described, but the middle or small ring is made of brass
wire or brazing metal, and when the parts have been put together and
raised to a brazing heat the middle ring melts and brazes the other two
rings to the barrel of the runner or top notch. The barrel of the top
notch may be made from the metal of one of the rings, the central
opening of the said ring being of such small diameter as to leave metal
enough for the formation of the short top notch barrel by the action of
raising tools. The other two rings are fitted on the short top notch
barrel thus made, and are brazed as already described.

filed by the said William Corder and Edward Shore in the Great
Seal Patent Office on the 2nd December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CORDER, of the Firm of Corder and Turley, of Birmingham, in tho
County of Warwick, Umbrella and Parasol Manufacturer, and EDWARD
SHORE, of Birmingham aforesaid, Tool Maker, send.greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of June, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said William Corder and Edward Shore, Her
special licence that we, the said William Corder and Edward Shore, our
executors, administrators, and assigns, or such others as we, the said
William Corder and Edward Shore, 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 THE MANUFACTURE
OF RUNNERS AND TOP NOTCHES FOR UMBRELLAS AND PARASOLS," upon the.
condition (amongst others) that we, the said William Corder and.
Edward Shore, our executors or administrators, by an instrument in.
writing under our, 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 Scal Patent Office within six calendar months next.
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Corder and Edward Shore,
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, reference being had to the Drawing
hereto annexed; and to the figures and letters marked thereon, that is to
say:
Our Invention has reference principally to that part of the said
runners and top notches called the notch, and our Invention consists

page_text: mainly of the improvements herein-after described in making the said
notch. And to make our Invention better understood we will proceed
to describe the same by reference to the accompanying Drawing.
According to our Invention we make the notch from three rings A, B,
and C, Figures 1, 2, and 3, of iron or other suitable metal, placed face
to face, the outer rings A and B being of greater diameter than the
middle ring C.
When the three rings are combined or united together, as shewn in
elevation at Figure 4, and section at Figure 5, a compound ring with a
groove a therein, answering the purpose of the usual grooved ring, is
thereby formed, the outer edge of the middle ring C of the compound
ring constituting the bottom of the groove a. In order to convert this
ring into a notch nicks are made across it radially. These nicks may
be made before or after the rings have been connected to the barrel of
the runner or top notch, which is made in the usual manner.
When the nicks are made in the rings before the said rings are con-
nected to the barrel the said nicks are pierced or cut out by dices and
tools worked in a press or stamp, one of such rings, being shewn in plan
in Figure 6.
We connect the rings to the end of the barrel of the runner or top 1
notch by brazing them thereto. The end of the barrel may be slightly
tapered and the rings are placed thercon; the edge of the barrel is then
turned into a flange to retain the rings in position during brazing; or
we may place the barrel on a peg vertically, and having placed the rings
at the top end of the barrel we force the rings down the barrel by means
of a hollow punch worked by a lever or in a press; in this case no flange
is required to be made on the edge of the barrel.
When plain or unnotched rings, similar to those shewn in Figures 1
and 2, have been brazed to the barrel the nicks are made in them in the
usual manner. After the notch has been completed the flange on the
barrel is removed by turning in a lathe, and the runner or top notch is
finished in the usual way; or the rings may be brazed to the barrel in
the following manner:-The outer rings A and B are made as herein.
before described, but the middle or small ring C is made of brass or
other wire or brazing metal, and when the parts have been put together a
and raised to a brazing heat the middle ring C will melt and braze the

page_text: .
other two rings A and B to the barrel of the runner or top notch. The
barrel of the top notch may be made from the metal of one of the three
rings, the central opening of the said ring being in such case made of
such a small diameter as will leave metal enough for the formation of the
short top notch barrel by the action of raising tools. The other two
rings are fitted on the short top notch barrel thus made, and are brazed
as herein-before described.
Having thus described our said Invention, and the best means with
which we are acquainted for carrying the same into effect, what we
claim is, the manufacture of the notches of runners and top notches of
umbrellas and parasols of three rings of metal, substantially in the
manner herein-before described.
In witness whereof, we, the said William Corder and Edward
Shore, have hereto set our hands and seals, this Thirtieth day
of November, One thousand eight hundred and seventy-four.
