Improvements in Telephone Closets and other Structures where it
is desirable that they should be practically Sound-proof.
1, THOMAS WEIGHILL of 24. Drury Lane in the City of Liverpool, Joiner, lo
hereby declare the nature of this invention to be as follows :-
:-
This invention has for its object a box or closet for a telephone which shall be
absolutely sound proof. Part of the invention is also available for making other
buildings or structures sound proof. In carrying out my invention I form the walls
in all cases of two thicknesses, at the corners or other points where there may be
posts. These posts are preferably lined on the inside, or outside, or both, with a
sheathing of wood or other material, and where two posts unite, and at the doors
where the two frames of the door come together I arrange rabbets or tongue pieces
in one fitting into the holes of the other, and form a double frame, the joint of one
frame being further back than the joint of the other.
.
The main walls of the structure I form hollow of panelling or boards, and
between these I fill in with fibrous peat worked up light like as in the case of peat
used for horse litter, it being the fibrous portion of the peat teased out to a light
woolly consistency. This I mix with sawdust, and pack loosely between the
frames. The box is in fact what is known in America as a lined frame building,
but in addition to the double sheathing and frame there is this filling in material,
a material which I believe has never been used for any such purpose before.
The inner walls of the box I prefer to line with felt. We have thus even by the
door posts two thicknesses of wood breaking joint with each other and at those
joints again having tongue pieces breaking the clear passage.
In other parts we
have (1) felt, (2) wooden sheathing, (3) peat and sawdust filling, and (4) the
panelling for the outside.

COMPLETE SPECIFICATION.
Improvements in Telephone Closets and other Structures where it
is desirable that they should be practically Sound-proof.
I, THOMAS WEIGHILL of 24, Drury Lane in the City of Liverpool, Joiner, 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 has for its object a box or closet for a telephone which shall be
absolutely sound-proof.
Part of the invention is also available for making other buildings or structures
sound-proof.
The invention is best described by aid of the accompanying drawings, in which :-
Figure 1 is a perspective view;
Figure 2, a sectional plan of a telephone box.
The walls are of two thicknesses A and B. These preferably overlap and cover
the posts at the corners or other parts as shown, and at the doors where the two
frames of the door come together I arrange rabbets or tongue pieces C in one
fitting into the holes of the other, and form a double frame D E, the joint of one
frame being further back than the joint of the other.

page_text: The main walls of the structure are thus formed hollow of panelling or boards,
and between these I fill in with fibrous peat worked up light as in the case of peat
used for horse litter, it being the fibrous portion of the peat teased out to a light
woolly consistency. This I use alone or mix with sawdust, spent tan or other like
material, and pack loosely between the frames. The box is, in fact, what is known
in America as a lined frame building, but, in addition to the double sheathing and
frame, there is this filling in material, a material which, I believe, has never been
used for any such purpose before.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The manufacture of telephone boxes, and other structures which are desired
to be practically sound-proof, of hollow walls and framed as described, the hollows
being filled with loose fibrous material.
2. In the construction of telephone boxes, walls, partitions or floorings which it is 1
desired shall be sound-proof, filling the hollow interiors of the walls with light
shredded peat, with or without the addition of other materials, substantially as
described.
