Improvements in School Slates, by which the Detachment of the
Slate from the Frame is Rendered Impossible.
I JAMES PEARSON of 9 Victoria Street Haslingden, in the County of
Lancaster, Yarn Agent do hereby declare the nature of this invention to be as
follows:-
.
:
In a slate properly prepared for writing purposes I drill, say on each of the four
sides three holes (more or less) at convenient distances to the outside edges; I then
attach to each side the frame for such side, securing each side of the frame, by
inserting a screw (or other fastening) through the frame, such screw or fastening
passing through the hole drilled through the slate, & fastening itself into the frame:
thus making the slate & the frame a fixity & immovable: I commonly use a
grooved frame as at present in use, but grooved sufficiently deep to enable me, to
drill through both slate & frame, and give ample holding surface on each to affix
my screw or other holdfast: Sometimes I vary the attachment of my slate; not
using the groove, but cutting away the front part of the frame, allowing the slate,
as it were, to be countersunk into the frame; and secured by the screws &c., into
the lower part of the frame.
1 also at times secure the slate by having the frames longitudinally made in
halves; i.e. the thickness of the frame is in halves, one fitting on to the other with
sufficient space taken out to admit of the slate being inserted and the whole screwed
together.
My invention is a school slate having holes drilled into the slate, enabling the
frames to be secured to the slate itself, by means of these holes: My invention
obviates the breaking away of the frames from the slate as is the case by any
system of framing at present in vogue.

COMPLETE SPECIFICATION.
Improvements in School Slates, by which the Detachment of the
Slate from the Frame is Rendered Impossible.
I, JAMES PEARSON, of 9 Victoria Street, Haslingden, in the County of
Lancaster, Yarn Agent, 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:-
My invention relates to improvements in school slates by which the detachment
of the slate from the frame is rendered impossible.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing, reference being had to letters and figures
marked thereon.
Fig. 1, is a front elevation.
Fig. 2, is an enlarged view of a part of the frame and slate.
Fig. 3, is a section of the slate in the frame.
Parts of some of the figures are broken off for convenience.
In a slate d properly prepared for writing purposes I drill on each of the four
sides three holes (more or less) at convenient distances to the outside edges; I then

page_text: attach to each side the frame a and securing each side of the frame by inserting
-screws c or other fastenings through the frame a, such screws or fastenings passing
through the hole drilled through the slate and fastening themselves into the frame-
thus making the frame and the slate itself a fixity and immovable.
'
I commonly use a grooved frame as at present in use, but grooved sufficiently
deep to enable me to drill through both slate and frame and give ample holding
surface on each to affix my screw or other hold fast. Sometimes I vary the attach-
ment of my-slate by-not using a groove but cutting away the front part of the
frame, allowing the slate as it were to be countersunk into the frame and secured
by screws etc. into the lower part of the frame; or the frame inay be made, in two
halves, one fitting on to the other with sufficient space taken out to admit of the
slate being inserted and the whole screwed together.
The object of my invention is to produce a school slate having holes drilled into
the slate, enabling the frames to be secured to the slate itself by means of screws
or the like, and to obviate the breaking away of the frames from the slate as is the
case by the system now in common use.
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. In a school slate, the combination of holes drilled through the slate and the
frame, with the screws or other fastening, substantially as herein described and
according to the accompanying drawing.
2. A school slate constructed and arranged substantially as described.
3. The method of having holes drilled into the slate enabling the frames to
be secured to the slate itself by means of screws or the like substantially as
described.
