ALFRED HAVILAH WOODWARD, of Birmingham, in the County of Warwick,
Penholder and Pen and Pencil Case Manufacturer. "IMPROVEMENTS IN COM-
BINED PEN AND PENCIL CASES, AND IN COMBINED PEN OR PENCIL AND TOOTHPICK
CASES."
My Invention has reference to the propelling and withdrawing mechanism of
combined pen and pencil cases, and combined pen or pencil and toothpick cases, and
my said Invention consists in constructing the said mechanism in the manner
herein-after described.
By ny Invention the pen or the pencil or the toothpick may at the pleasure
of the user be propelled from the case and made ready for use by rotating part of
the case in one or other direction.
I will describe my Invention as applied to a combined pen and pencil case.
I make the rotating, propelling, and withdrawing inner tube of the case with two
kinds of helical slots, that is, I make in one half of the tube a helical slot arranged
around the tube like the thread of a right-handed quick threaded screw, and I make
in the other half of the tube a helical slot arranged around the tube like the thread
of a left-handed quick threaded screw. I will call one of these helical slots the right-
handed helical slot, and the other slot the left-handed helical slot. Within this
compound helically slotted tube the ordinary longitudinally slotted tube is situated.
The stud of the pencil case engages and works in the longitudinal slot of the inner
tube, and also engages in the right-handed helical slot of the propelling tube, and
similarly the stud of the penholder engages and works in the longitudinal slot of
the inner tube, and also engages in the left-handed helical slot of the propelling
tube.
The result of this arrangement is that when the propelling tube is turned by the
outside tube of the case the studs of the penholder and pencil case are made to
travel in opposite directions in the longitudinal slot in the inner tube by the action

page_text: upon them of the right and left-handed belical slots of the propelling tube, the said
studs either approaching one another at the middle of the case or separating from
one another. A sliding motion is thereby given to the penholder and pencil case
in opposite directions, so that while the pencil case is being propelled from the case
the penholder is being withdrawn into the case, and the reverse.
By constructing the helically slotted propelling and withdrawing tube in the
manner described, and the combination therewith of the penholder and pencil case,
the rotation of one of the two outer parts of the case in one or other direction
causes, say, the penholder to be propelled from the case ready for use, and the
reverse motion of the said outer part of the case causes the pencil case to be
propelled from the case ready for use, and the penholder at the same time to be
withdrawn into the case; thus either the pencil case or the penholder may be
propelled from the case at the pleasure of the user by turning the outside part of
the case in one or other direction.
I apply my Invention to combined pen and toothpick cases and combined pencil
and toothpick cases in the manner described with respect to a combined pen and
pencil case.
