Improvements in or relating to Frame Fastenings for Writing
Slates, and for other purposes.
I, JOHN WILLIAM WILLIAMS of Britannia Slate Works, Llanfairpwll, County
of Anglesey, Wales, Slate Manufacturer do hereby declare the nature of this
invention to be as follows:-
This invention relates to the fastenings of the pieces of frames especially
suitable for use with writing slates although the fastenings may be used for other
purposes I will describe the invention as applied to a writing slate.
The frame in appearance is the ordinary frame consisting of four pieces of wood
or other material adapted to the four sides of the usual rectangular piece of slate
fitted together angularly at each corner in substantially the usual manner.
I prefer
to employ a small tongue and groove at each joint though this is not essential.
Through the joint and preferably perpendicular to the plane of the joint I run a
tube or peg of any suitable material say for example a brass tube; this may be
covered with glue cement or other adhesive material if desired and when inserted
the ends may be expanded rivetted over or otherwise secured so as to prevent it
from coming out. This provides a strong and efficient means of securing the parts
together, and where the tube is used a string or equivalent may be run through it
by which the slate may be hung up.
It is desirable to glue or cement the joint in the ordinary manner in addition to
the use of the pegs or tubes. Where metal pegs are employed the ends may be
bent over and driven into the frame as a convenient means of fastening them.
Where wooden pegs are employed the glue will be sufficient to hold them. Either
pegs or tubes may be tapered as desired and they may be screwed for the whole
or a portion of their length as a means of fastening them in the frame or they may
be tapered or provided with heads and nuts or washers may be applied to the
smaller ends for securing them. Where a wire or equivalent peg is used the ends
of one or all of them may if desired be brought round and joined so as to form a
loop by which the slate can be suspended.

Improvements in or relating to Frame Fastenings for Writing
Slates, and for other purposes.
1, JOHN WILLIAM WILLIAMS of Britannia Slate Works, Llanfairpwll, County
of Anglesey, Wales, Slate 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 relates to the fastenings of the pieces of frames especially
suitable for use with writing slates although the fastenings may be used for other

page_text: purposes-I will describe the invention as applied to a writing slate in which
connection I have shown it applied in the accompanying drawings wherein; -
Fig. 1 is a plan of one form of frame or writing-slate constructed according to
my invention.
Fig. 2 an enlarged sectional view of a portion thereof.
Fig. 3 is a perspective view of another form of the frame, and
Fig. 4 is a view similar to Fig. 2 but showing a modification.
Like letters indicate like parts throughout the drawings.
The frame A in appearance is the ordinary frame, consisting of four
pieces A¹ A' of wood or other material, adapted to the four sides of the usual
rectangular piece of slate B fitted together angularly at each corner in sub-
stantially the usual manner. I prefer to employ a small tongue A and groove or
fork A at each joint though this is not essential. Through the joint and
preferably perpendicular to the plane of the joint I run a tube or peg C of any
suitable material say for example. a brass tube; this may be covered with glue,
cement or other adhesive material, if desired, and when inserted the ends may
be expanded or rivetted over as shown in Fig. 2, or otherwise secured so as
to prevent it from coming out. This provides a strong and efficient means of
securing the parts together, and where the tube is used as in Figs. 1 and 2, and
as hereinafter described in reference to Fig. 3, a string or equivalent may be
run through it, by which the slate may be hung up.
It is desirable to glue or cement the joint in the ordinary manner in addition to
the use of the pegs or tubes.
The joints of the frame shown in Fig. 3 are of the type known as tenon and
mortise mitre joints, the tenons being secured in the mortises by glue or other
adhesive cement, and also by the tubes or tubular rivets C which in this example
as distinguished from that previously described pass diagonally across the corners
in a plane coinciding with or parallel to that of the frame A. or writing surfaces of
the slate B. The tubes C may be rivetted over at the ends or secured in the frame
by glue or cement, or in any other convenient manner.
Where solid metal pegs such as D Fig. 4 are employed, the ends may be bent
over and driven into the frame as a convenient means of fastening them, and so
as, at the same time to form a loop D¹ through which string may be passed for
hanging up the slate. Either pegs or tubes may be tapered as desired, and they
may be screwed for the whole or a portion of their length as a means of fastening
them in the frame, or they may be tapered or provided with heads and nuts or
washers may be applied to the smaller ends for securing them.
If desired, only one of the corners of the frame may be secured in the manner
before described; or any other required number may be so fitted.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1. The combination with a slate-frame or equivalent of a tubular rivet such as C
substantially as and for the purpose described and illustrated in Figures 1 and 2
or Figure 3 of the accompanying drawings.
2. The combination with a slate-frame or equivalent of a tubular rivet such as C
passing through one of its corners or joints in a direction perpendicular to the plane
of the frame or writing surface of the slate substantially as described and illustrated
in Figures 1 and 2 of the accompanying drawings.
3. The combination with a slate frame or equivalent of a tubular rivet such as C
passing diagonally through one of its corners or joints substantially as described
and illustrated in Figure 3 of the accompanying drawings.
4. The combination with a slate frame or equivalent of a stud or peg for securing
one of its corners or joints so formed or bent as to constitute a loop or eye sub-
stantially as and for the purpose described and illustrated in Figure 3 of the
accompanying drawings.

page_text: 5. A joint for the frame of a slate or equivalent substantially as and for the
purpose described and illustrated in Figures 1 and 2 or in Figures 3 or 4 of the
accompanying drawings.
