1 JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman 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:-
The Invention is directed to that kind of holder for pens and like articles in which
the sheath or case containing said article is provided with a self closing cover or
stopper for its mouth.
It is characterized by the combination with the sheath of a self closing cover which
in opening or closing the sheath moves in a plane with the mouth of the sheath or
in other words in a plane at right angles to the axis of the sheath.
There is no forward movement of the cover. It simply swings to one side in a plane
parallel with the mouth of the sheath.
In the accompanying drawings. Figure 1 is a longitudinal central section partly
in elevation of a penholder embodying the Invention in its preferred form. Figure 2
is a perspective view of the holder with the sheath mouth upward and with the cover
swung to one side of the mouth of the sheath. In this figure a part of the sheath
is broken away to shew more plainly the parts which cooperate to thus move the
cover.
A is the sheath. B is a pen holder (typical of any article to be contained in said
sheath) which can freely slide back and forth within the sheath.
At the mouth of the sheath is the cover C which is fast to a rod D supported and
adapted to turn or rotate in bearings a within said sheath. By turning this rod it
will cause the cover to swing to one side of the mouth as in Figure 2 or to move the
mouth so as to cover it according to the direction of rotation of the said rod. The
cover is self closing or spring closed. A convenient arrangement for this purpose is
shewn in the drawings. The rear end of the rod D has formed in it a quick spiral
thread or groove b of sufficient length to give the necessary range of movement to

page_text: the cover.
On this thread is mounted a nut e which is fast to the inner end of a
stem d. This stem is attached to the pressure cap E, which is normally retracted or
pushed back by the retracting spring F contained in a spring-case G and interposed
between the bottom of said case and the head of the cap. The spring case is inserted
and made fast in the rear end of the sheath and the stem d passes through an opening
in the bottom of the spring case. In the normal position of these parts (shewn in
Figure 1) the cover closes the mouth of the sheath."
By pushing forward the pressure cap against the stress of the retracting spring the
nut is caused to travel forward upon the rod D and in so doing by reason of its
engagement with the spiral thread or groove it causes the rod D to rotate in a
direction to swing the cover C to one side of the mouth as seen in figure 2. The
moment pressure is removed from the pressure cap the retracting spring throws the
cap back, by which movement the nut is retracted to the position seen in Figure 1
and the rod D is consequently rotated in a direction and to an extent sufficient to
again bring the cover over the mouth of the sheath.
When the cover is swung to one side as in Figure 2 and the sheath is turned mouth
downward the pen holder B will drop out or protrude from the mouth of the sheath
to the permitted extent as shewn in figure 1. In the pen holder there is formed a
notch e at the point opposite which the cover comes when the penholder is in protruded
position. As soon as the pressure cap is released the cover by the action of the
retracting spring will be turned and drawn into this notch as seen in the figure last
referred to.
The pen holder has in its side a longitudinal groove or passage at to accommodate
the rod D.
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 :-
1. The combination with the sheath, of a spring closing cover for the mouth of the
same, hinged to turn upon an axis which is at right angles with the plane of tho
mouth of the cover substantially as and for the purposes horeinbefore set forth.
2. The combination with the sheath and the freely sliding pen holder or other
article contained within the same, of the spring closing cover, hinged to turn upon
an axis which is at right angles with the mouth of the cover, and arranged and adapted
to operate in connection with said sheath and pen holder substantially in the manner
and for the purposes hereinbefore set forth.
3. The combination of the sheath, the cover, the rotatable rod by which said cover
is carried, provided with a spiral thread or groove as described the pressure cap, the
retracting spring and the nut engaging said thread and attached to and moving with
said pressure cap these parts being combined and arranged for joint operation
substantially as hereinhefore set forth.
4. The combination of the sheath, the freely sliding pen holder or other article
contained in said sheath, the cover for closing the sheath, and for locking the protruded
pen holder in place, the rotatable rod D carrying said cover and provided with a spiral
groove or thread, the pressure cap the retracting spring and the nut engaging said
thread and attached to and moving with the pressure cap, the combination being and
acting substantially as herein before set forth.
