PROVISIONAL SPECIFICATION.
Improvements in Slates.
I SAMUEL BLOUNT JACKSON of 158 High Street, Bangor, N. Wales, Hotel
Keeper, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improvel slate, and is intended to provide an
arrangement of framing which will permit the same frame to be used over again
when the slate gets broken, also presenting other advantages.
The slate instead of being fixed in a wooden frame of the ordinary description
formed from four pieces of wood grooved to receive the edges of the slate, and
nailed or otherwise fixed together, I propose to form the frame of similar shape,
but made from india-rubber of the proper hardness. The slate can be inserted in
this frame by stretching the sides slightly, and the frame thus grips the edges of
he slate with some force, rendering the arrangement thoroughly firm and rigid.
To insert the slate in place a small device is used, which stretches the sides of the
rame, and guides the slate into the grooves. With this arrangement the noise
commonly made when collecting slates in schools and packing them together is
entirely obviated, and the arrangement is much more convenient for use.
Dated this 6th day of December 1894.

Improvements in Slates.
I, SAMUEL BLOUNT JACKSON of 158, High Street, Bangor, N. Wales, Hotel
Keeper 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 relates to an improved slate, and is intended to provide an
arrangement of framing which will permit the same frame to be used over again
when the slate gets broken, also presenting other advantages.
The slate instead of being fixed in a wooden frame of the ordinary description
formed from four pieces of wood grooved to receive the edge of the slate, and
nailed or otherwise fixed together, I propose to form the frame of somewhat similar
shape, but made from india-rubber of the proper hardness. The slate can be
inserted in this frame by stretching the sides slightly, and the frame thus grips the
edges of the slate with some force, rendering the arrangement thoroughly firin and
rigid. To insert the slate in place, the sides of the frame are stretched, and the
slate guided into the grooves. With this arrangement the noise commonly made
when collecting slates in schools and packing them together is entirely obviated,
and the arrangement is much more convenient for use.
In order that the invention may be more clearly understood, reference i had to
the accompanying drawing, which shows my improved slate in cross section. A is
the slate which is enclosed in the rubber frame B.

page_text: According to the arrangement I prefer to employ, the frame extends over the
face of the slate only at one side, the slate being flush with the top of the frame
as shown in the drawing. By this means a ruler can be laid on the slate without
resting on a raised surface, and thus being situated a short distance from the surface
of the slate. This enables the ruler to be used in a more convenient manner.
The frame may of course project over the edges of the slate at both sides, as in the
case of the ordinary frame. The slate can be fixed into the frame by forming
perforations in both of the sides passing through the holes small eyelets which
are fixed in the usual manner, or rivets of any suitable material may be
employed.
Instead of fastenings of this or similar description, cement or adhesive material
may be employed. The frame can be made of solid rubber or may if found
desirable be hollow, and can have the alphabet or numerals or other device
impressed upon it. I also prefer to form a cavity in the frame for the reception
of slate pencil.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.―
(1) Improvements in school and like slates, consisting in providing the slate
with a frame formed from india-rubber, hardened to the required degree,
substantially as described and for the purposes specified.
(2) The improved slate for school and like purposes, substantially as described
and shown in the accompanying drawing, and for the purposes specified.
Dated this 7th day of September 1895.
