COMPLETE SPECIFICATION.
Improvements in and connected with School Slates.
I, EVAN REESE, of Mount Pleasant, Machynlleth, in the County of Montgomery,
Slate Works Manager and Auctioneer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to the frames of school slates, and its objects are:-To
enable the slates to be framed economically with strong and durable frames, to
provide a closable receptacle or receptacles for holding the pencils used with the
slates; and, if desired, to provide also, means for sharpening the pencils.
I will describe my invention with reference to the accompanying drawings, in
which
Figure 1 is a plan, with part of the slate and of the framing broken away to shew.
the construction more clearly; and
Figure 2, a vertical section.
An
A is the slate and B the frame. The slate may be the natural slate commonly
used or any artificial substitute therefor. The frame may be constructed of wood
or composition, but it is preferably constructed of sheet metal and it is mitred at
the corners in the usual manner. Each of the corners is strengthened and protected
by corner plates or corner caps C, one of which is hinged or pivoted as at C¹, so
that it may be turned back on the pivot as shewn by the drawings Figure 1.
opening D, is left or formed in this corner which communicates with an opening or
openings formed longitudinally in one or both of the contiguous bars of the frame,
as shewn at F, Figure 2. This longitudinal opening, or each of them when there
are two, forms a receptacle for the pencil or pencils, one pencil being shewn in the
opening at G, Figure 1. To insert or remove the pencil, it is necessary only to
move the hinged corner cap into the position shewn in Figure 1, insert or remove
the pencil, and then to close the cap. The removal of the pencil is easily effected
by holding the mouth of the pencil receptacle downwards, when the pencil will fall
out and drop into the hand.
If it be desired to provide means for sharpening the pencils, I form upon, or
secure to, each or any of the edges of the frame a semicircular or other con-
veniently shaped recess or groove which is serrated notched toothed or roughened
as for example by mechanical means or by treatment with a coat of varnish or
other suitable cementitious drying material sprinkled whilst in a tacky or sticky
condition with emery crushed glass and the like.
In the drawings, I have represented the frame as being constructed of sheet
metal. Means for producing the required section by rolling and otherwise are
well known to workers in sheet metal and do not therefore require to be herein
described, but I would have it to be understood that I do not limit myself to
the precise form illustrated as this may be considerably varied. The longitudinal
opening for the reception of the pencil in the case illustrated, is the hollow part
of the frame, and it does not therefore require to be specially produced. In the
case of wood and composition frames, the opening or openings may be produced
by boring or by moulding as the case may be, and in case of pencil sharpening
by the insertion in the frame of the semicircular or other conveniently shaped
recess or groove as hereinbefore described.
In the case of the pivoted corner piece, this should be a cap, or should have a
lateral extension to cover the opening D, so that when closed, it will box in the
pencil or pencils completely. The other corner pieces may be either caps or
corner plates, and they may be soldered or sweated in place on metal frames, or
pinned on or otherwise secured to wooden or composition frames.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. School slates having metallic frames constructed substantially as hereinbefore
described and as illustrated by the accompanying drawings.
2. In a school slate, a longitudinal opening formed in one bar, or in each of two
contiguous bars of the frame, substantially as and for the purpose hereinbefore
described.
3. In a school slate, the combination with a longitudinal opening or two
longitudinal openings in the frame for the reception of a pencil or pencils, of a
pivoted or hinged corner piece, constructed substantially as and for the purpose
described and as illustrated by the accompanying drawings.
4. In the frame of a school slate, a toothed roughened or serrated longitudinal
recess or recesses constructed and arranged substantially as and for the purpose
herein before described and as illustrated by the accompanying drawings.
Dated this 16th day of November A.D. 1892.
