Improvements in the Sticks of Umbrellas and Parasols.
I, WILLIAM HOLLAND, the Younger, of Grantham Road, Sparkbrook, in the
City of Birmingham, Manager of Works do hereby declare the nature of this
invention to be as follows :-
My invention has for its object, a metallic cased stick or cane for umbrellas and
parasols.
In close-wrapping umbrellas and parasols, the sticks employed are required to be
slender, or small in circumference, and to accomplish this, hollow metallic sticks
have been employed, but in consequence of the same having to be of considerable
strength and rigidity, the metal employed is considerable, consequently the said
stick becomes heavy, and adds considerably to the weight of the said articles.
By providing prepared and trued sticks or canes with metallic shell coverings or
metallic sheathings, considerable strength with rigidity and lightness is thereby
attained, consequent upon the sticks having a light exterior casing of metal, and a
wood or cane interior, which latter forms an internal body support to the said
metallic or outer casing.
In carrying out one form of my invention in connection with a seamless casing, I
cut a metallic blank form ductile sheet metal or alloy, and during the said cutting
out, I may shallow cup and elongate the said blank into a moderately deep cup.
then reduce in diameter, and elongate the said cup, by passing the same through a
die, or other drawing expedient, such as rolls, or a die or dies in conjunction with
an ordinary drawbench.
This shell is then subsequently reduced in diameter, and elongated to nearly the
length of the stick to be encased, and having an inside bore equal to, or slightly
larger than, the outside diameter of the said stick or cane.
The prepared stick or cane is then placed within the metallic sheath or shell
covering, and the same drawn down to a less diameter, which still reduces in girth,
and increases in length, the metallic casing and at the same time, compresses the
stick or cane forming the internal support, hence a metallic wood or cane stick.
I wish it to be understood that I do not limit myself to the number of passings,
reducings or finishings, as these may be varied according to the character and
nature of the stick required.
As a further form of my invention I make the casing from drawn down sheet
metal, produced upon a bulbous mandril, or upon a slightly tapered mandril, of the
diameter, or of about the diameter of the stick to be encased.
The operation of encasing is performed as before described, by finally drawing
the said metal casing upon the wood interior.
In carrying out another form of my invention, for a cheap metallic cased stick, I
take a length of strip metal and turn the same into an open jointed tube, with the
adjacent boundary edges slightly turned inwards.
The wood interior to be covered is then slipped into the casing, and the whole
slightly reduced by a finishing process, which completely closes the joint, and
presses the turned-in edges of the metal into the wood of the internal support.
As a still further form of my invention I take a length of strip metal, and bend
the same into an open joint, and with the terminal side edges of the same connected
together by a fold-over joint, coming inwards, when by drawing the said case-
covered stick through a die, a perfect casing is produced, with a seam running down
its middle.
As still another form, I take a thin brazed tube, of a bore a little greater than

page_text: that of the stick, and then by a further drawing process, contract and slightly
elongate the brazed tube upon the stick.

COMPLETE SPECIFICATION.
Improvements in the Sticks of Umbrellas and Parasols.
I, WILLIAM HOLLAND, the Younger, of Grantham Road, Sparkbrook, in the
City of Birmingham, Manager of Works, 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. :-
My invention has for its object, a metallic cased stick or cane for umbrellas and
parasols.
In close-wrapped umbrellas and parasols, the sticks employed are required to be
slender, or small in circumference, and to accomplish this, hollow metallic sticks
have been employed, but in consequence of the same having to be of considerable
strength and rigidity, the thickness of the metal employed is considerable, con-
sequently the said stick becomes heavy, and adds considerably to the weight of the
said articles.
By providing prepared and trued sticks or canes with metallic shell coverings or
metallic sheathings, considerable strength, with rigidity and lightness is thereby
attained consequent upon the sticks having a light exterior casing of metal, and a
wood or cane exterior, which latter forms an internal body support to the said
metallic or outer casing.
In carrying out one form of my invention, in connection with a seamless casing,
I cut a metallic blank from ductile sheet metal or alloy, and during the said cutting-
out, I may shallow cup and elongate the said blank into a moderately deep cup.
then reduce in diameter, and elongate the said cup, by passing the same through a
die, or other drawing expedient, such as rolls, or a die or dies in conjunction with
an ordinary draw-bench."
This shell is then subsequently reduced in diameter, and clongated to nearly the
length of the stick to be encased, and having an inside bore equal to or slightly
larger than, the outside diameter of the said stick or cane.
The prepared stick or cane is then placed within the metallic sheath or shell
covering, and the same drawn down to a less diameter, which still reduces in girth,
and increases in length, the metallic casing, and at the same time, compresses the
stick or cane forming the internal support, hence a metallic cased wood or cane
stick.
I wish it to be understood that I do not limit myself to the number of passings,
reducings or finishings, as these may be varied according to the character and nature
of the stick required.
As a further form of my invention, I make the casing from drawn down
sheet metal, produced upon a bulbous or other mandril, or upon a slightly
tapered mandril, of the diameter or of about the diameter of the stick to be
encased.
The operation of encasing is performed, as before described, by finally drawing
the said metal casing upon the wood interior.
In carrying out another form of my invention for a cheap metallic cased stick, I
take a length of strip metal, and turn the same into an open jointed tube, with the
adjacent boundary edges slightly turned inwards.
The wood interior to be covered is then slipped into the casing, and the whole

page_text: slightly reduced by a finishing process, which completely closes the joint, and
presses the turned in edges of the metal into the wood of the internal support.
As a still further form of my invention, I take a length of strip metal, and bend
the same into an open joint, and with the terminal side edges of the same connected
together by a fold-over joint, coming inwards, when by drawing the said case-
covered stick through a die, a perfect casing is produced, with a scam running down
its middle.
As still another form, I take a thin brazed tube, of a bore a little greater than
that of the stick, and then by a further drawing process, contract and slightly
elongate the brazed tube upon the stick.
Figure 1 of the accompanying drawing represents, partly in section and partly in
elevation, a metal-cased umbrella stick made according to one form of my invention.
It will be seen that the said umbrella stick is composed partly of metal and partly
of wood, and that the metal, which is employed in the form of a covering or sheath,
is made seamless, whilst the wood of the stick forms an internal body support to the
said scamless casing.
Figure 2 represents a transverse section of the same upon the dotted lines A Br
Figure 3 represents an umbrella provided with a metal cased stick as aforesaid.
Figures 4, 5 and 6 represent partly drawn metal blanks to form the long length.
of casing Figure 7, which is shown broken off at its middle to indicate that the said
casing may be of any desired length.
Figure 8 represents a longitudinal vertical section of the same.
Figure 9 represents the stick or cane which is to form the internal body support
of wood.
Figure 10 represents the thin metal sheath or thin metal tubular casing being
drawn upon the stick or cane.
Thus in carrying out one form of my invention in connection with a seamless
casing, cut out and cup a blank of sheet metal as in Figure 4.
Then by a
drawing through process, I elongate the same, and reduce the thickness of its walls
into an elongated cup-shaped blank Figure 5. Then by subsequent drawings
through, I further elongate and reduce the thickness of the metal of the walls of
the same as in Figure 6. I then by a further series of drawings-through, transform
the elongated tubular blank Figure 6 into a long tube or shell Figure 7, whose-
walls have become greatly reduced in thickness, and with an inside bore about
equal to, or a little greater than, the outside diameter of the stick or cane Figure 9,
which is placed within the interior of the said shell Figures 7 and 8, and then by a
further pass through a drawing-through tool, the said casing is drawn and closed
upon the wood interior, reducing the diameter of the casing, and at the same time-
compressing the wood, stick or cane thus encased (see Figure 10).
a is the thin seamless sheet metal casing and b is the stick, cane or non-metallic
internal support.
In carrying out a further form of my invention, I take a thin strip of metal
Figure 11, of which the edge view is shown in Figure 12, and fold the same up into.
an open jointed tube Figure 13, with the boundary edges slightly turned inwards.
into flanges, which on the casing being drawn over a stick or cane, pierce the same,.
and form means of connecting the casing to the internal stick support, and also.
prevent the joint from opening. The diameter of the wood with casing may be
reduced by a further drawing through during the operation of finishing.
Figure 14 represents an elevation of the said cased stick, so as to show that the
same inay be made of any length.
Figure 15 represents a transverse section on the dotted lines C D Figure 14.
Figure 16 is an enlarged view of Figure 15.
In Figures 11 to 16, a is the outside casing, a² are the turned-in edges of the strip,.
and is the stick or non-metallic internal support.
Figure 17 represents upon an enlarged scale another form of casing, with a seam
having a fold over joint.

page_text: a is the outer casing made from thin sheet metal, and a³, the fold-over joint,
whilst bis the interior stick or non-metallic internal support.
Figure 18 represents upon an enlarged scale, a section of a seamed metallic cased
stick, with a soldered joint. In carrying out this part of my invention, I take ȧ
strip of thin sheet metal as in Figures 11, fold the same into an open jointed tube,
and then braze or solder the joint. The stick is then placed within its interior, and
the casing is drawn upon the stick.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First: An unbrella or parasol stick, consisting of a metallic or metal cased
stick or cane, substantially as set forth.
Secondly: An umbrella or parasol stick; drawing upon a wood or cane interior
body part or internal support, a seamless metallic casing or tube, substantially as
set forth.
Thirdly An umbrella or parasol stick, drawing upon a wood or caue interior
body part or internal support, a seamed metallic casing or tube, substantially as set
forth.
