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 James Alfred Foster, of Birmingham,
aforesaid, Tool Maker, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF THE RIBS OF UMBRELLAS AND PARASOLS, AND IN MACHINERY
DDED BAD LEHAT PUDDAGE"
PROVISIONAL SPECIFICATION left by the said William Corder and
James Alfred Foster at the Office of the Commissioners of Patents,
with their Petition, on the 4th March 1874.
We, WILLIAM CORDER, of the Firm of Corder .and Turley, of
Birmingham, in the County of Warwick, Umbrella and Parasol Manu-
facturers, and JAMES ALFRED FOSTER, of Birmingham, aforesaid, Tool
Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF THE RIBS OF UMBRELLAS AND PARASOLS, AND IN
MACHINERY TO BE USED FOR THAT PURPOSE," to be as follows:-
-
Our Invention has reference to the manufacture of those parts of the
ribs of umbrellas and parasols called the tips.

page_text: In the ordinary method of making the said tips they are made solid
or in one piece with the wire of which the rib is made by means of press
tools; the said press tools acting laterally on the end of the wire and
producing a solid tip or nearly spherical head of the same diameter as
the wire.
According to our Invention we make the solid tip or nearly spherical
head of the rib by upsetting or compressing the metal of the wire in the
direction of the length of the wire, whereby we produce a solid tip or
nearly spherical head of a diameter larger than that of the wire from
which it is made. We prefer to effect the said upsetting or longitudinal
compression of the end of the wire to form the solid tip or nearly spherical
head of the rib by means of machinery, the parts of which are con-
structed and arranged in the following manner :-
The said machinery consists essentially of a pair of gripping tools, a
sliding stop, and a horizontal heading or compressing tool. One of the
gripping tools is fixed on the bed of the machine, and the other has a
vertical motion in guides. The gripping face of each of the gripping
tools has in it a semi-cylindrical groove of a size proper to hold and grip
the wire to be tipped, and the vertical faces of the gripping tools when
closed have in them a hemispherical depression terminating the gripping
grooves. The sliding stop works between the pair of gripping tools and
the heading or compressing tool. The said heading or compressing tool
has a hemispherical depression in its acting face, between which and the
hemispherical depression in the gripping tools the tip or head of the rib
is formed. The compressing tool is fixed to a horizontal sliding bolt
working in a dovetail on the bed of the machine. The moveable
gripping tool, the sliding stop, and the heading bolt are actuated by
levers, and the latter by cams on the driving shaft of the machine.
甲
The action of the machine is as follows:-The wire or length of wire
from which a rib is to be made is fed by hand or automatically into the
groove in the lower fixed grip, and against the stop in front thereof, the
said stop being in its advanced or acting position. The moveable grip
descends and grips the wire between itself and the fixed grip a portion
of the wire sufficient to form the tip or head of the rib protruding from
the said grips. The stop now retires from the front of the grips, and
the heading or compressing tool advances horizontally and upsets or
compresses that part of the wire protruding from the grips, and forms.

page_text: therefrom the tip or nearly spherical head on the end of the rib wire.
The tip having been thus made the compressing tool retires and the
upper grip rises and releases the partly made rib, which is removed
from the grip by hand or by a knocker off, when another wire is fed to
the fixed grin, and the actions described are repeated.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Corder and James Alfred Foster in the
Great Seal Patent Office on the 1st September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CORDER, of tho Firm of Corder and Turley, of Birmingham, in the
County of Warwick, Umbrella and Parasol Manufacturers, and JAMES
ALFRED FOSTER, of Birmingham, aforesaid, Tool Maker, send greeting.

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 THE RIBS OF UMBRELLAS AND PARASOLS,
AND IN MACHINERY TO BE USED FOR THAT PURPOSE," upon the condition
(amongst others) that we, the said William Corder and James Alfred
Foster, 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 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 William Corder, on behalf of myself
and the said James Alfred Foster, 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 to the manufacture of those parts of the
ribs of umbrellas and parasols called the tips, by means of the improved
machinery hercin-after described.
By our improved machinery we make the solid tip or nearly spherical 1
head of the rib by upsetting or compressing the metal of the wire in the
direction of the length of the wire, and produce a solid tip or nearly
spherical head of a diameter larger than that of the wire from which it
is made in a more economical manner than hitherto.
The said machinery consists essentially of a pair of gripping tools, a 1
sliding stop, and a horizontal heading or compressing tool. One of the
gripping tools is fixed on the bolster of the machine, and the other has a
vertical motion in guides. The gripping face of each of the gripping
tools has in it a semi-cylindrical groove of a size proper to hold and grip
the wire to be tipped; and the vertical faces of the gripping tools when :
closed have in them a hemispherical depression terminating the gripping
grooves. The sliding stop works between the pair of gripping tools and
the heading or compressing tool. The said heading or compressing tool
has a hemispherical depression in its acting face, between which and the
hemispherical depression in the gripping tools the tip or head of the rib
is formed. The compressing tool is fixed to a horizontal sliding bolt
working in a dovetail on the bed of the machine. The moveable
gripping tool, the sliding stop, and the heading bolt, are actuated by
levers, and the latter by cams on the driving shaft of the machine.
Having thus described the nature of our said Invention we will now.
proceed to more particularly describe the same and the best means we.
are acquainted with for carrying the same into effect by reference to the
accompanying Drawing in which Figure 1 is a plan; Figure 2, a front
elevation; and Figure 3, a side clevation of our improved machinery for
forming the solid tip or nearly spherical head on the ribs of umbrellas
and parasols; Figures 4, 5, 6, and 7, detached full size views of the
gripping tools; Figures 8 and 9, detached views of the heading tool; ·

page_text: and Figure 10, a section shewing the gripping tools and heading tool
closed or in the position they occupy at the termination of the operation
for forming the solid tip. Similar letters in all the Figures represent
similar parts.
A is the cast-iron framing for carrying the whole of the parts of the
machinery; a is the lower gripping tool fixed on the bolster 6 of the
machine; c is the upper gripping tool fixed by the set screw to
.
the false nose g on the lower end of the vertical bolt h, moving in the
framing A and kept therein by the plate B bolted to the front of the
framing by the bolts d; i is a lever moving on a centre at j, one end of
this lever i is connected to the bolt h, and the other end carries a vertical
adjustable arm k, the lower end of which carries a friction roller i
bearing on the cam m on the driving shaft D. At each revolution of
the driving shaft the cam m acting on the arm k will cause the lover i
to move on its centre or fulcrum at j, thereby moving the bolt hand
with it the upper gripping tool downwards as herein-after described.
(
n, Figure 10, shews the semi-cylindrical groove in the gripping face of
cach of the gripping tools a and c, such grooves. being terminated by the
depressions o, o, Figures 5 and 7, in the vertical faces of the tools.so as
to form when the tools are closed a hemispherical depression; p is the
sliding stop fixed to the rod a working in the guides », r, and moved
forward so as to bring the stop p between the gripping tools a, c, and
the heading tools by means of the cam t on the driving shaft D;
u, spiral spring for drawing back the sliding stop p when the cam t
ccases to act on the rod q; & is the heading tool fixed to the end of the
horizontal sliding bolt e working in a dovetail in the bed of the machine;
this, bolt is. actuated by the lever C moving on a centre at E, and
having a slot w at its inner end, through which passes the pin or stud x
on the bolt e; the other end of the lever E carries a friction roller G,
and is actuated at the required time by the projection t' of the cam t;
y, spring for bringing the lever C to its normal position after having
been operated upon by the cam t; F, F', fast and loose pulleys; H, fly
wheel.
The action of the machine is as follows:-The machine being set in
motion and the parts being in the position shown in Figures 1, 2, and 3,
of the Drawing; the wire or length of wire from which a rib is to be
made is fed by hand into the groove n (Figure 10) in the lower fixed

page_text: grip a, the end of the wire resting against the stop p which is in its
advanced position; the cam m acting on the arm k will cause the lever i to
move on its centre j, thereby depressing the upper grip c which will
grip the wire between itself and the fixed grip a, a portion of the wire
sufficient to form the head or tip of the rib protruding from the said
grips. The stop p is now withdrawn by the recoil of the spring u from
the front of the grips, and the projection t' of the cam t acting on the
lever C, the heading or compressing tools will advance horizontally and
upset or compress that part of the wire protruding from the grips, and
form therefrom the tip or nearly spherical head on the end of the rib
wire. The tip having been thus made the compressing tools is moved
away from the grips by the recoil of the spring y, and the upper grip c.
will rise and release the partly made rib which is removed from the grip
by hand; another rib is then fed to the fixed grip a and the herein-
before described actions are repcated, and so on for each revolution of
the driving shaft.
Having thus described our said Invention and the best means we are
acquainted with for carrying the same into effect, what we claim is, the
combination with vertical gripping tools and a horizontal heading tool
of a sliding stop arranged and operating substantially in the manner
and for the purposes herein-before described and represented in the
accompanying Drawing.
In witness whereof, I, the said William Corder, have hereto set
my hand and seal, this Twenty-eighth day of August, in the
year of our Lord One thousand eight hundred and seventy-
four.
