page_text: LETTERS PATENT to John Forrest Walters, of 7, Queen's Road, Bayswater,
late of Boston, in the United States of America, and William Pickering, of
Arundel Street, Strand, in the County of Middlesex, for an Invention of
PROVISIONAL SPECIFICATION left by the said John Forrest Walters and

JOHN FORREST WALTERS, of 7, Queen's Road, Bayswater, late of Boston, in the
United States of America, and WILLIAM PICKERING, of Arundel Street, Strand,
in the County of Middlesex. "IMPROVEMENTS CONNECTED WITH SCHOOL SLATES."
This Invention relates to certain improvements with school slates, and con-
sists in marking or scoring on one or on both of the aide or end surfaces
of the wooden or other frame, and also in grooving or channelling the under
surfaces for the reception of and as a guide for a strip of wooden or other material
to slide or be slid up or down or along the surface of the slate for lines to be
drawn or other marks to be made at distances apart, according to the scoring or
marking on the sides of the frame. The strip of wood or other material may be
solid, and scored or marked to enable lines to be drawn or other marks made in an
opposite direction to those of the other lines or marks; or the strip of wood or its
equivalent may be perforated for that purpose.

JOHN FORREST WALTERS, of 7, Queen's Road, Bayswater, late of Boston, in the
United States of America, and WILLIAM PICKERING, of Arundel Street, Strand,
in the County of Middlesex. "IMPROVEMENTS CONNECTED WITH SCHOOL SLATES."
This Invention relates to certain improvements connected with school slates,
and consist, as shown in the annexed Sheet of Drawings, in marking or scoring
on one or on both of the side A or end surfaces B of the wooden or other frame,
and also in grooving or channelling the under surfaces from C to D for the reception
of and as a guide for a strip of wood E or other material to slide or be slid up or
down, as indicated at Figure 1, over the surface of the slate or along it, as in
Figure 2, for lines to be drawn or other marks to be made at distances apart,
according to the scoring or marking on the sides of the frame. The strip of wood
or other material E may be solid or slotted, as in Figure 1, and scored or marked
to enable lines to be drawn or other marks made in an opposite direction to those
of the other lines or marks; or the strip of wood or its equivalent may be perforated
for that purpose.
By our Invention children can easily and at an early age decipher and understand
the divisions of linear measurement.
Having now described the naturo of our said Invention, and in what manner
the same is to be performed, we declare that we claim,-
Fitting a strip or strips, plain or marked, in the frame of a school slate to bo
slid over the surface and used in combination with scored or marked sides and
ends, or sides only, to facilitate distancing of lines on said alate, and serving to
teach divisions of measurements in an easy and early stage of a pupil's education,
as set forth.
In witness whereof, wo, the said John Forrest Walters and William
Pickering, have hereunto set our hands and seals, this Nineteenth day of
December, in the year of our Lord One thousand eight hundred and
aighty ana
