ALFRED HAVILAH WOODWARD, of Birmingham, in the County of Warwick,
Penholder and Pen and Pencil Case Manufacturer. IMPROVEMENTS IN THE
MANUFACTURE OF COMBINED PEN AND PENCIL CASES, AND COMBINED PEN OR
PENCIL CASES AND TOOTH-PICK CASES."
"
My Invention relates to combined pen and pencil cases and combined pen or
pencil cases and tooth pick cases, in which either the pen or pencil or the tooth
pick may, at the pleasure of the user, be propelled from the case and withdrawn
into it by rotating one part of the case upon the other part.
I will describe my Invention as applied to a combined pen and pencil ease.
The propelling and withdrawing of the pen and pencil are ordinarily effected by
means of two helical slots, one on one half of the propelling tube, and the other on
the other half of the propelling tube, the said slots terminating near each other at
or near the middle of the tube. One of these slots has the figure of a right banded
quick-threaded screw, and the other slot has the figure of a left handed quick-
threaded screw.
In the ordinary method of manufacture, the slots are cut in a piece of tubing
manufactured in the ordinary way, and the sides of the slots require to be smoothed
or burnished so as to remove the burr left by the cutting tool in order that the
pins or studs working in the slots may move therein with sufficient smoothness and
freedom.
In manufacturing the propelling and withdrawing mechanism according to my
Invention, I employ two tubes, that is, instead of making the two helical grooves or
slots in one continuous piece of ordinary tubing, I employ two pieces of tubing
(made as hereinafter described), each of the tubes being of half the length of the
Din 21

page_text: single tube ordinarily employed. One of the two tubes contains the right handed
and the other the left handed belical slot.
I make these tubes by taking a strip_of_sheet metal and affixing one end of it to
a rotating mandril fixed in a lathe. By the rotation of the mandril the strip-of
metal is coiled on the mandril. By pressure applied to the coil on the mandril, the
_metal is hardened, and by inserting a pin on the mandril between the opposed
edges of the coil at its end, and passing-the-said-pin from end to end of the coil
-between the.said edges (which is effected by holding the coil stationary and rotating
the mandril or the reverse), the edges are separated-to-the-distance necessary to
-form-the-required slot. This coiled and helically slotted tubing may be made in
lengths, and afterwards divided into short pieces of the required size.
In using the slotted tubes made as described, two of the said tubes, equal in
length to the one tube ordinarily employed, are placed upon the conducter tube of
the case, one of the said tubes having a right handed, and the other a left handed
helical slot. A ring is placed at the middle of the conducter tube, against which
ring the inner ends of the slotted tubes bear.

the said Alfred Havilah Woodward in the Great Seal Patent Office on the
15th July 1879.
ALFRED HAVILAH WOODWARD; of Birminghain, in the County of Warwick,
Penholder and Pen and Pencil Case Manufacturer. "IMPROVEMENTS IN THE
MANUFACTURE OF COMBINED PEN AND PENCIL CASES, AND COMBINED PEN OR
PENCIL CASES AND TOOTH PICK CASES."
My Invention relates to combined pen and pencil cases, and combined pen or
pencil cases and tooth pick cases, in which either the pen or pencil or the toothpick
may, at the pleasure of the user, be propelled from the case and withdrawn into it
by rotating one part of the case upon the other part.
I will describe my Invention as applied to a combined pen and pencil case.
The propelling and withdrawing of the pen and pencil are ordinarily effected by
means of two helical slots, one on one half of the propelling tube, and the other on
the other half of the propelling tube, the said slots terminating near each other at
or near the middle of the tube. One of these slots has the figure of a right handed
quick threaded screw, and the other slot has the figure of a left handed quick
threaded screw.
In the ordinary method of manufacture, the slots are cut in a piece of tubing
manufactured in the ordinary way, and the sides of the slots require to be smoothed
or burnished so as to remove the burr left by the cutting tool in order that the
pins or studs working in the slots may move therein with sufficient smoothness and
freedom.
In manufacturing the propelling and withdrawing mechanism according to my
Invention, I employ two tubes, that is, instead of making the two helical grooves
or slots in one continuous piece of ordinary tubing, I employ two pieces of tubing
(made as hereinafter described), each of the tubes being of about half the length of
the single tube ordinarily employed. One of the two tubes contains the right
handed and the other the left handed helical slot.
I make these tubes by taking a strip of sheet metal and affixing one end of it to
a rotating mandril fixed in a lathe. By the rotation of the mandril the strip of
metal is coiled on the mandril. By pressure applied to the coil on the mandril, the
metal is hardened, and by inserting a pin on the mandril between the opposed
edges of the coil at its end, and passing the said pin from end to end of the coil
between the said edges (which is effected by holding the coil stationary and rotating
the mandril or the reverse), the edges are separated to the distance necessary to
form the required slot. This coiled and helically slotted tubing may be made in
lengths, and afterwards divided into short pieces of the required size.
In using the slotted tubes made as described, two of the said tubes, equal in
length to the one tube ordinarily employed, are placed upon the conductor tube of
the case, one of the said tubes having a right handed, and the other a left handed
helical slot. A ring is placed at the middle of the conductor tube, against which
ring the inner ends of the slotted tubes bear. In completing the case, the upper
half of the case is attached to the inner ends of both the slotted tubes, which being
thus rigidly connected, become virtually one tube, and act as the one helically
slotted tube of the ordinary manufacture acts. The other half of the case is soldered
to the collar at the front or open end of the pen and pencil case. The manufac-
ture in respects other than those described resembles the ordinary manufacture.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my Invention may be performed.
In making the long length of slotted tube, having say, a left handed helical slot
in it, I take a strip of sheet metal of the kind represented in plan and edge view in
Figure 1, one end of the said strip being pierced with a hole at a, and having the
angle cut off near the said hole. I also take the rotating mandril 6 of a lathe,
'

page_text: represented in Figure 2 for coiling the said strip into a tube, the said mandril being
provided with a pin c near its screwed end, and with a smaller pin d near its
opposite end. The said-pins-c-and-d-are_for_the purposes hereinafter described.
The mandril-b having been screwed into the head e of a lathe as represented in
Figure 3, the hole a in the end of the strip is engaged with the pin c on the mandril
b. A rotatory motion-being-given-to-the mandril, the strip of metal is coiled upon
the mandril so as to form a tube, having-a-close-helical slot in it as represented-in
Figure-3 By-pressure applied to the coil by a pair of plyers or other pressing or
burnishing tool during the rotation of the mandril-and-coil,-the metal of the said
coil is hardened. The end of the hardened coil is next removed from the pin c on
the mandril b, and a pin d is inserted in the opposite end of the mandril and passed
between the opposed edges of the coil at the end most distant from that which was
fastened to the mandril. The coil being held stationary and the mandril rotated,
the coil is made to travel upon the fixed pin d from one end to its other end. By
this treatment the edges of the coil are separated or expanded to the distance
necessary to form the required slot in the tube.
Figure 4 represents the tube after a portion of it has been operated upon by the
pin d, the right hand end of the several convolutions of the coiled tube being repre-
sented opened out or separated by the operation of the pin d upon the opposed
edges of the said convolutions.
Figure 5 represents a length of tube having a left handed helical slot in it made
as described.
Figure 6 represents a length of tube having a right handed helical slot in it.
The slotted tube, Figure 6, is made in the manner described with respect to the
slotted tube, Figure 5, excepting that the strip of metal, Figure 1, is coiled upon
the mandril b in an opposite direction to that in which the strip to form the left
handed slotted tube, Figure 5, is coiled.
I cut the right and left handed slotted tubes, Figures 5 and 6, into pieces of such
a length that two of them joined together will form the propelling and withdrawing
slotted tube of the combined pen and pencil case.
Figures 7 and 8 represent two of such lengths or pieces, one cut from a right
handed slotted tube, and the other from a left handed slotted tube.
The two slotted tubes, Figures 7 and 8, are next furnished with a cross slot at f,
and gaps at h, h, as represented in Figure 9, for the studs of the pen and pencil to
_work in as usual.
In using the slotted tubes i, k, Figure 9, I take the ordinary conductor tube l,
Figure 10, containing the ordinary longitudinal slots 'm, m. In the slot mi, the
stud 2 of the pen works, and in the slot n on the opposite side of the other half of
the conductor tube, the stud 2 of the pencil works. A ring being placed on the
conductor tube 1, Figure 10, at the middle thereof, the two slotted tubes i, k, are
placed upon the said conductor tube as represented in Figure 11, and the studs p, q,
engaged with the slots-of-the-respective slotted tubes, the inner ends of the said
slotted tubes bearing against the ring r. A collet or rings is next soldered-to-each-
end of the conductor tube l, so as to retain the slotted tubes i, k, on 'the conductor
tube.
The case is now in the state represented in Figures 12 and 13, Figure 12 repre-
senting the pen in its propelled position, and Figure 13 the pencil u in its
propelled position. In completing the case, the thin outer tube at the upper half
of the case is soldered to the inner ends of the two slotted tubes i, k, which tubes
being thus rigidly connected together become virtually one tube, as represented in
the completed case represented in section in Figure 14, and in elevation and plan in
Figure 15. The other half w of the outer tube of the case is soldered to the cap x,
which latter is pinned to the conductor tube 7.
By rotating either the upper part v of the outer tube or the lower part w of the
said outer tube, the other part being held stationary, the pen t or the pencil u may
.be.propelled from or withdrawn into the case at the pleasure of the user.
I manufacture the slotted tubes of the propelling and withdrawing mechanism of

page_text: combined pen or pencil cases and toothpick cases in the manner described with
respect to a combined pen and pencil case.
Having now described the nature of my Invention and the manner in which the
same is to be performed, I wish it to be understood that I do not limit myself to
the precise details herein described and illustrated, as the same may be varied
without departing from the nature of my Invention.
But I claim as my Invention:-The improvements in the manufacture of com-
bined pen and pencil cases, and combined pen or pencil cases and toothpick cases
herein before described and illustrated in the accompanying Drawings, that is to
say, making the right handed and left handed helically slotted tubes constituting
part of the propelling and withdrawing mechanism of cases of the kind described,
by taking strips of sheet metal and coiling them helically upon a rotating mandril,
so as to form tubes having close helical slots, and afterwards opening or expanding
the helical slots in the coiled strips or tubes, substantially in the manner described
and illustrated, the long lengths of slotted tubes thus made being cut into short
pieces or lengths, and two of the said short lengths, one having a right handed
helical slot, and the other a left handed helical slot, being secured on the conductor
tube, and finally rigidly connected together, substantially as described and
illustrated.
In witness whereof, I, the said Alfred Havilah Woodward, have hereunto set
my hand and seal, this Seventh day of July, in the year of our Lord
One thousand eight hundred and seventy nine.
