Improvements in Picture Mouldings, Looking-glass Frames, and
the like.
1; GEORGE FREDERICK RESTALL, of 82 Commercial Road, Bournemouth, in
the County of Hampshire Estate Agent, 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 improvements in picture moulding, looking-glass frames,
and the like, its object being to prevent the admission of dust between the same
and the glass or the backing.
According to this invention I secure to that part of the moulding against which
the glass or backing rests a layer of baize, or other fabric, india-rubber, asbestos,
string, or other suitable yielding material. This makes a tight joint between the
glass or backing and the moulding and so prevents the admission of dust and
consequent injury to the picture. It is obvious that if a waterproof material is
employed for packing, the joint will be damp-proof.
And in order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accom-
panying sheet of drawings illustrative of the various methods of carrying this
invention into effect.
Each figure is a transverse section of a piece of picture moulding provided with
a yielding packing in the manner herein described. As shown at Figure 1 the
portion a of the moulding overhanging the glass is recessed at b to receive the
yielding packing c which is secured therein by means of any suitable cement.
The depth of the recess b is less than the thickness of the packing c in order that
when the same is compressed the edge of the beading a may not bear against the
glass.
In a modified form of this arrangement the recess 6 is dispensed with, the
packing material being secured by means of a suitable cement to the underside of
the part a of the beading. As shown at Figure 2 the packing is secured in this
manner but an additional piece of packing is secured to the edge d of the beading
so that the wood or other material usually employed to back the picture may take
a bearing against this part of the packing and so prevent the admission of dust
without the necessity of pasting paper over the joint. Figure 3 shows a modified
form of this arrangement in which the surface d instead of lying at a right angle to
the surface of the picture is inclined thereto so that any pressure brought to bear
upon the backing of the picture serves to make a tighter joint between the said
backing and the packing. Figure 4 shows another modification of this arrange-
ment the packing c in this case is only secured to the beading at one edge so that it
is free to fold in with the glass and picture as the same is introduced. Figure 5
shows another arrangement which is similar to that shown at Figure 1 with an
additional piece of yielding packing c² which is inserted in a diagonal saw-cut in the
face d of the beading. This second piece of packing serves to make a joint with
the backing of the picture in a manner already described. As shown at Figure 6
the packing c is held within a dovetail groove b so that the use of cement is not
necessary. When india-rubber or other waterproof packing is employed it may
conveniently be of the shape shown.
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 :-
The hereinbefore described improvements in picture beadings, looking-glass

page_text: frames, and the like, whereby the admission of dust and damp is prevented both by
way of the front and the back of the picture, looking-glass, etc., substantially as and
for the purpose hereinbefore set forth and described and illustrated in the
accompanying drawings.
Dated this 3rd day of February 1893.
