PROVISIONAL SPECIFICATION.
Improvements relating to Slate and other Writing Tablets, and to
Covers therefor.
I, BRUNO HERMANN HECHT, of Meerane, in the Empire of Germany, Machine
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention consists in certain improvements upon the slate or other writing
tablets usually termed slates, and relates to providing the said slate with a cover
similar to those of books or collecting portfolios so as to protect the slate against
breakage and also the writing thereon from being rubbed out.
Moreover as young
scholars in their first studies seldom require more than a slate, the said cover of the
slate will at the same time replace the otherwise desirable satchel or portfolio.
The arrangement may be made so that the cover is held in position on the
framning by a spring in connection with or without a groove; or a backing without
spring device may be arranged while the fixing on the frame is directly effected by
means of clasps or cramp hooks. Furthermore the inside of the cover may be
provided with signs, lesson hours or other useful information; also any supplementary
closing contrivance for still better securing the contents may be applied.
The essence of the improvement however rests in the slate being provided with a
fixed or removable cover.

COMPLETE SPECIFICATION.
Improvements relating to Slate and other Writing Tablets, and to
Covers therefor.
I, BRUNO HERMANN HECHT, of Meerane, in the Empire of Germany, Machine
Manufacturer, 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 consists in certain improvements upon the slate or other writing
tablets usually termed slates, and relates to providing the said slate with a cover
similar to those of books or collecting portfolios so as to protect the slate against
breakage and also the writing thereon from being rubbed out.
Moreover as young
scholars in their first studies seldom require more than a slate, the said cover of the
slate will at the same time replace the otherwise desirable satchel or portfolio.
The arrangement may be made so that the cover is held in position on the
framing by a spring in connection with or without a groove; or a backing without
spring device may be arranged while the fixing on the frame is directly effected by
means of clasps or cramp hooks.
Furthermore the inside of the cover may be provided with signs, lesson hours or
other useful information; also any supplementary closing contrivance for still
better securing the contents may be applied.
The essence of the improvement however rests in the slate being provided with a
fixed or removable cover.
In the annexed drawings, Fig. 1 is a side elevation of a slate with cover, Fig. 2
[Price 8d.]

page_text: is a section thereof on line M M, Fig. 3 is a similar section showing the cover open,
Fig. 4 shows the slate removed.
In this construction A is the slate, D is the frame, B the boards of the cover
and a the back or hinge thereof. The frame D is made with two grooves b b one
on each face near to one of its side edges, and into these grooves the projecting
edges of the spring back a engage when the cover is closed.
Fig. 5 is a side elevation and Fig. 6 a cross section of a modification wherein
the cover is secured to the frame by pins d traversing holes c in the cover and
frame and secured by the rod d passing through their perforated ends f. The cover
is held closed by a clasp.
Fig. 7 is a side elevation and Fig. 8 is a cross section on line OO of another
modification in which the cover is secured on a rounded edge of the frame by an
outer sheath or channel shaped spring F, this rounded edge may be perforated along
its axis as at E to afford a receiver for the pencil, the sheath F is removable by
sliding it off endways. Fig. 9 shows this cover opened. Fig. 10 is a cross section
thereof on line P P and Fig. 11 is a section in the plane of the hinge.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed. I declare that what
I claim is ;-
The combination with a framed slate or other writing tablet of a cover having its
hinge or backing attached upon one edge of the frame of said slate or tablet
whereby the boards B cover the slate, the said cover being affixed removably to
the slate and held closed thereon substantially in the manner described.
