Improvements in Umbrella Runners and in Machinery for the
Manufacture of Umbrella Runners.
We, ALFRED CECIL WRIGHT, and JAMES LESLIE WRIGHT, trading as
Wright & Harrington, of 260 Bradford Street, Manufacturers, and RICHARD
BUDD, of Gladstone Road, Sparkbrook, Foreman for the said firm, all in the City
of Birmingham, do bereby declare the nature of this invention to be as
follows:-
:-
This invention has reference to umbrella runners, the barrel of which is made
from sheet metal, and consists in the improvements hereinafter described in the
metal runners, and in the machinery for the manufacture of umbrella runners.
The improvement or improvements in metal umbrella runners constituting part
of our invention consists in making the barrel portion of our runners with a large
beaded end in order that the striking of the spring upon the slot end may not
cause the metal to burr over or form a cutting or scratching edge likely to damage
the stick when being moved up or down. We are also enabled to form a convenient
projection for the more ready manipulation of the runner, by our improved enlarged
end or bead.
We construct the body portion of our runner from metal sheet formed into tubes,
or from metal tubes direct, in the usual well known manner, and we attach thereto
the usual runner notch for connecting to the ribs. The slot we pierce in the
usual manner, but the end we hollow out or with an expanded surface or bead
so that the end of the slot against which the spring strikes is above the portion of
the barrel or tube of the runner, fitting more closely upon the stick.
This form of bead and enlarged end we have previously produced in solid metal
runners in the manner set forth in the Specification of our Patent No. 20,177 of
1889, but we now produce the same by our improved machinery out of ordinary tube
or sheet metal runners.
The improvements in the machinery employed in carrying the improved manu-
facture described into effect, consists in the use of a movable spinning tool and a
pointed central chuck spindle which permits of the outer end of the tube being
spun or forced out from the surface of the barrel or tube to form an enlarged end.
or hollow bead.
We cut the tube off into lengths or press up a barrel out of sheet metal in
any usual well known manner; we then transfer it to our improved chuck carried
upon a spindle within a lathe or other machine. The spindle we form with a collar
or shoulder against which the chuck may be pressed; the free end of the spindle
we make with one part to fit the hole in our chuck, so that it can slide freely upon
t, and with the outer portion reduced down for a length sufficient to receive the
barrel or runner tube. The chuck we construct with internal expanding jaws or'
plit cones having a hole within of sufficient diameter to receive the barrel or runner
ube at one end, and to fit upon the spindle at the other end.
The spindle we provide with a point to project beyond the end of the chuck,.
o that when the case or tube is placed within the chuck, and it is moved along.to
ecurely connect it to the spindle, the chuck with its contained case may revolve
ith the point of the spindle standing out from the chuck.
Upon another portion of our machine or upon the sliding spindle of our lathe
eadstock, we attach our improved swivelling spinning over tool which we formu
ith a conical hole upon its free end to suit the point of the chuck spindle. The
ther end we form with a swivelling joint or hinge, and we attach this hinged
pol to the end of our sliding spindle, or to any other portion of our machine.

projecting bead or ball to suit the bead or projection to be produced upon the
runner barrel. And after bringing this tool against the point of the chuck
spindle, the projection or ball surface is caused to slide over this point of the
chuck spindle, and force out or spin out the free projecting end of the tube
outside the chuck, thus forming the hollow bead or enlarged end upon the runner
tube.
We sometimes transfer the tube thus expanded to another machine having a
spindle shaped with a bulb end to suit the runner, and a corresponding circular block
or former having a groove or wide ring formed upon its outer surface into which the
metal is rolled or pressed.
The end of the bead or hollow projection we form of double thickness by
turning over the end of the tube in an earlier operation in the usual ordinary
manner, or by spinning it over when forcing out the metal to form the bead.
We construct our improved runners of any required length and the bead of any
desired configuration of a circular character."

COMPLETE SPECIFICATION.
Improvements in Umbrella Runners and in Machinery for the
Manufacture of Umbrella Runners.
We, ALFRED CECIL WRIGHT and JAMES LESLIE WRIGHT, trading as
Wright and Harrington, of 260 Bradford Street, Manufacturers, and RICHARD
BUDD, of Gladstone Road, Sparkbrook, Foreman for the said firm, all in the City
of Birmingham, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention has reference to umbrella runners, the barrel of which is made
from sheet metal, and consists in the improvements hereinafter described in the
metal runners, and in the machinery for the manufacture of umbrella runners.
The improvement or improvements in metal umbrella runners constituting part
of our invention consists in making the barrel portion of our runners with a large
beaded end in order that the striking of the spring upon the slot end may not cause
the metal to burr over or form a cutting or scratching edge likely to damage the
stick when being moved up or down. We are also enabled to form a convenient
projection for the more ready manipulation of the runner, by our improved enlarged
end or bead.
We construct the body portion of our runner from metal sheet formed into tubes,
or from metal tubes direct, in the usual well known manner, and we attach thereto
the usual runner notch for connecting to the ribs. The slot we pierce in the
usual manner, but the end we hollow out or form with an expanded surface or
bead so that the end of the slot against which the spring strikes is above the
portion of the barrel or tube of the runner, fitting more closely upon the stick.
This form of bead and enlarged end we have previously produced in solid metal
runners in the manner set forth in the Specification of our Patent No. 20,177 of
1889, but we now produce the same by our improved machinery out of ordinary
tube or sheet metal runners.
In the accompanying sheet of explanatory drawings,
Figure 1 is a sectional elevation of our improved chuck spindle A in, position
upon the lathe or machine spindle B, and Figure 2 is a plan of the same.
Figure 3 is a sectional elevation of our improved runner.
Figure 4 is a sectional elevation and Figure 5 a plan of our improved spinning
tool.

page_text: Figure 6 is a detailed elevation of our chuck clip.
Figure 7 is a general arrangement of our improved lathe or machine, and
Figure 8 is a plan of the same.
The improvements in the machinery employed in carrying the manufacture of
our improved runners into effect, consists in the use of a movable spinning tool C
and a pointed central chuck spindle A which permits of the outer end of the
tube or runner D being spun or forced out from the surface of the barrel or tube
to form an enlarged end or hollow bead d.
We cut the tube off into lengths or press up a barrel out of sheet metal in
any usual well known manner; we then transfer it to our improved chuck E
carried upon a spindle B within a lathe or other machine. The spindle we form
with a collar or shoulder against which the chuck E may be pressed; the
free end of the spindle B' we make with one part b' to fit the hole in our chuck,
so that it can slide freely upon it, and with the outer portion reduced down for
a length sufficient to receive the barrel or runner tube D. The chuck E we
construct with internal expanding jaws or split cones E' having a hole within
of sufficient diameter to receive the barrel or runner tube at one end, and to fit
upon the spindle at the other end. The spindle we provide with a point or
centre A to project beyond the end of the chuck, so that when the case or tube D
is placed within the chuck, and it is moved along to securely connect it to the
spindle, the chuck with its contained case may revolve with the point of the
spindle standing out from the chuck as shown in Figures 2, 6 and 7.
Upon another portion of our machine or upon the sliding spindle of our lathe
headstock, we attach our improved swivelling spinning tool C which we form with
a conical hole or a conical head upon its free end to suit the point of the chuck
spindle. The other end we form with a swivelling joint or hinge c', and we
attach this hinged tool to the end of our sliding spindle F, or to any other
portion of our machine employed for this purpose. The spinning surface of our
tool we form with a projecting bead or ball to suit the bead or projection to
be produced upon the runner barrel. And after bringing the free end of the
tool C against the point A of the chuck spindle, the projection or ball surface c
is caused to slide over this point of the chuck spindle, and to force out or spin out
the projecting end of the tube D outside the chuck, thus forming the hollow bead
or enlarged end d upon the runner tube.
We sometimes transfer the tube thus expanded to another machine having a
spindle shaped with a bulb end to suit the runner, and a corresponding circular
block or former having a groove or wide ring formed upon its outer surface into
which the metal is rolled or pressed.
The end of the bead or hollow projection we form of double thickness by turning
in the end of the tube in an earlier operation in the usual ordinary manner, or by
spinning when forcing out the metal to form the bead.
We construct our improved runners of any required length, and the bead of any
desired configuration of a circular character."
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The construction of metal runners for umbrellas having an enlarged or
beaded end formed thereupon substantially as and for the purposes herein before
described and as illustrated in Figure 3 of the accompanying drawings.
2. The construction and arrangement of machines for spinning over metal
tubes substantially as and for the purposes hereinbefore described and as illustrated
in the accompanying drawings.
3. The construction of swivelling spinning or burring over tools such as C
substantially as hereinbefore described and as illustrated in the accompanying
drawings.
4. The construction of a spring chuck such as E having a central spindle

page_text: such as B, & and a fixed or separate projecting' head such as A, substantially as
and for the purposes hereinbefore described and as illustrated in the accompanying
drawings.
