COMPLETE SPECIFICATION.
An Improved Combined Pencil Case and Sharpener.
I, ELMER EGBERT MONROE, of 125 Washington Street, Brighton, Massachusetts,
United States of America, Clerk, 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 for its object to construct a combined pencil and sharpener,
which when assembled in condition for use has all the appearance and feeling of an
ordinary lead pencil.
In accordance with this invention the body of the pencil is made in two longitudinal
sections provided with means at the ends for attaching them together.
One section is designed to receive the lead which is held by a suitable clamping
device or other contrivance, and means are provided for advancing the lead as may
be required.
The other section is cut away to receive a small flat file which may be a metallic
file or piece of emery cloth, or other equivalent abrasive device, and when the two
sections are separated the file may be used to point the lead.
The lead-holder consists essentially of a lead-receiving tube, and a sheath
containing it, the latter being made of a size which permits the lead-receiving tube
to freely move in and out, and said sheath is fitted into and held by the cylindrical
or pencil-form case.
The lead-receiving tube and its sheath are so constructed and arranged that
by turning the pencil, point downward, the lead-receiving tube will fall by gravity
out of the sheath until its movement in such direction is checked by a suitable
stop, and then by pressing the point against a stationary object, or against the
finger, the lead-receiving tube is pushed inward a very short distance and becomes
locked.
The lead-receiving tube when so locked is released or disengaged by hand, and
returned by sliding it into its sheath.
Figure 1, shows in side elevation a combined pencil and sharpener embodying
this invention.

holding sections together.

and locked.
Figure 6, a detail of the lead-receiving tube removed to show the lead-advancing
device, and,

Figure 8, a detail of the fin.
The lead-holding section of the pencil consists of a cylindrical section or
case a having a more or less conical or pointed end, with a hole or bore made
through it axially.
The upper end portion of this cylindrical body a is split diametrically, and a
half section e thus removed for a short distance.

page_text: This Intter section constitutes the file-carrying section, and is formed with one
end bevelled to enter a corresponding under-cut in the portion a.
This half section supports or bears at its outer end a ferrule which is
rotatable thereon, and said ferrule embraces the outer end of the pencil a when
the parts are placed together with the bevelled end of the section e in the underent
portion provided for it."
The ferrule has one or more inwardly formed projections, and the parts
which it embraces have corresponding notches or recesses adapted to receive said
projections.
When the parts are placed together and the ferrule turned one way its
projections enter the notches in the part a, and thereby lock the parts together.
and when said ferrule is turned in the opposite way said projections disengage
said notches and enter the notches in the part e, and with the ferrule in such position
the file-carrying sections may be removed.
The inner or abutting face of the file-carrying section e is cut away to receive
the file e which may be made as a strip of emery cloth or as a metallic file.
When it is desired to sharpen the point of the pencil this file-carrying section is
removed, and the file used for this purpose.
The part or section a which is bored axially contains within it the lend holder
which consists of a lead-receiving tube b, and a sheath c containing it.
The sheath is secured within the bore of the part a.
The lead-receiving tube b is made as a split tube to form a clamp for the lead,
being slightly contracted at the end for this purpose.
The longitudinal opening in said tube has formed upon one side of it a series of
notches, and a spring clip & is placed within said tube, having a projection which
slightly protrudes from the side opening to be engaged by the finger nail, to be
moved along, and thereby advance the lead.
This projection is slightly turned or bent laterally, so as to engage the notches,
and by them the clip is positively held against movement in the opposite direction.
The lend is thereby held from dropping out by the contracted clamp-like end,
and the spring clip engaging the notches prevents the lead from being pushed in
while using it.
The shenthe is made large enough for the lead-receiving tube to slide freely
therein longitudinally.
The sheath has a slit at a opening into a cut-away portion at one side
thereof, and a slite leading from the opposite end of said cut-away portion, and
at the opposite side thereof, extending to or toward the opposite end, and the
lead-receiving tube has a lin & made sufficiently narrow to pass freely along said
slits c' nude.
As the lead-receiving tube moves in and out it will be turned axially as the fin
passes along or through the cut-away portion c².
This axial movement is provided for the purpose of enabling the parts to he
easily locked together.
Herein it will be seen that the upper edge of the cut-away portion is made
straight from side to side, and the fin is made more or less tapering, and
as the lead-receiving tube is withdrawn by gravity or otherwise, the axial movement
given to it brings the fin into proper position, below the straight edge of said
cut-away portion, so that by pressing the point of the lead against a stationary
object said tapering fin will be pushed into engagement with said straight edge of
said cut-away portion, and the parts will be thereby locked together.
To turn the lead-receiving tube axially automatically as it passes out of its
sheath I have formed one side of the cut-away portion with a cam surface against
which said fin bears, to be turned by it into proper position directly below the
straight wall or side of said cut-away portion.
This lead-holder may be used separately from the sharpening contrivance above
described.
I do not desire to limit my invention to the particular construction shown in

page_text: carrying out all parts of my invention, or to the employment of both the lead
controlling and operating devices, and the sharpener.
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
