PROVISIONAL SPECIFICATION.
Improvements in Slates.
I FRANK SAMUEL PETT of 27 Buckland Avenue Dover Master Mariner do
hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in school or other slates having for
object the providing of slates (framed or otherwise) with a suitable handle (rigid
or otherwise). I at present prefer to so construct & attach the handle to the
slate (or its frame) that it does not prevent the slate from being laid flat on a
desk or table.
I may make the handle of wire or other suitable material & attach it to the
frame of the slate or to the slate itself as found most suitable or I may make the
upper frame (to which the handle is attached) & handle in one.
Again I may make & attach the handle so that the slate is free to swing or I
may secure the handle in such a manner to the slate or its frame that it is
rigid.
The handle of the slate may be made of any desired form & size & may be
secured to frame or slate as found most suitable.
Dated this 1st day of April 1893.
COMPLETE SPECIFICATION.
Improvements in Slates.
I FRANK SAMUEL PETT of 27 Buckland Avenue, Dover, Master Mariner,
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 for improvements in slates relates to framed slates for school and
other purposes; and has for its object to provide the said slate with a handle that
shall not project beyond the planes of the frame when the frame is laid flat on a
desk or other surface; and consists essentially in forming the handle out of wire
or strip metal and attaching it rigidly or by means of hinges to the frame of the
slate so as to leave no projecting parts.
A slate provided with a handle constructed according to this invention can be
carried without cutting the fingers of the carrier and can be easily picked up off
a flat surface by the teacher, examiner, schoolmaster-or-the-like.
In the accompanying sheet of illustrative drawings :-
Fig. 1 is a face view of a portion of a slate partly in section, showing a simple
wire handle and
Fig. 2 is a cross section of the same through the handle.
A U-shaped piece of wire to form the handle a is inserted centrally through the
top bar 6 of the slate frame, its ends are then turned over as shown at c and the
handle drawn back so that the ends enter the recesses d cut at the bottom of
the groove in which the slate proper is fixed.
In the modification shown in Figs. 3 and 4 small eyelets e are screwed into the
top bar b of the slate frame and the ends of the handle a are bent round the
evelets as shown at f

page_text: Fig. 5 shows a handle a either round or flat secured to the top bar of the slate
by the spikes g.
In the case of round wire the turned over ends h are flattened.
Fig. 6 shows a handle similar to Fig. 1 except that the ends c are turned inwards
instead of outwards.
Fig. 7 shows a U-shaped handle a secured in the top bar b of the slate by
means of the washers i and riveted ends or heads l. The washers and ends?
are received in recesses d.
Fig. 8 shows a similar arrangement to Fig. 7 with the washers i omitted, the
riveted ends or heads & securing the handle a.
Fig. 9 shows a U-shaped handle secured in the top bar of the slate by resin,
cement glue or other similar substance.
Fig. 10 shows a U-shaped handle a adapted to be driven into the top bar of the
-slate frame and having barbed ends m so that it cannot be withdrawn.
Fig. 11 shows a similar arrangement to Fig. 10 except that the ends n of the
handle are grooved or roughened.
Fig. 12 shows an open handle of flat or round metal adapted to be secured to the
top barb by a central screw o. When formed of round metal the part through
which the screw passes is flattened out.
Fig. 13 is a similar arrangement to Fig. 12 showing a closed handle.
Fig. 14 shows a U-shaped handle a that is inserted through the top bar b and
prevented from being again withdrawn by pins p passing through holes in the ends
of the handle. The handle is drawn back after the pins are in place until the
pins enter the recesses d.
In the modification shown in Figs. 15 and 16 the ends of the handle a are bent
to form eyes which pass first through holes s provided in the frame of the slate,
the sides of the eyes being received in slots t formed in the side of the frame
from the holes s upwards thus enabling the sides of the ends of the handle_to lie
flush with the frame so that there are no projecting parts of the handle. It will
be obvious that the ends of the handle a must be inserted through the holes s before
.the eyes r are completed.
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. A school or other slate provided with a handle so constructed and attached
as to allow the said slate to lie flat on either side on the desk substantially as
.described.
2. A handle for school and other like slates constructed in such manner that no
parts project beyond the planes of the surfaces of the frame substantially as
described for the purpose specified.
3. A handle for school and other like slates substantially as described with
reference to the drawings for the purpose specified.
