66 Improvements in the Floors of Rooms and Buildings."
I, MEDLEY HALL, of No 29 Northgate, Halifax, in the County of York, Architect,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of floors of rooms
and buildings specially designed for dancing purposes, the object being to: con-
struct a floor having a certain amount of spring or elasticity and the requisite
strength and stability. The improvements hereinafter described can be applied
to existing floors equally as well as to floors in the course of construction.
According to this invention a floor is constructed in the ordinary manner, and
on or to this floor is applied the improved spring floor constructed as follows:--
Across the ordinary floor are laid a series of joists parallel to one another, and
each joist is concave on its underside, the outer ends forming fect on which the
joists rest, and between each foot of each joist is placed a pad of rubber or other
elastic body, and about the apex of the concave portion and between the same
and the ordinary floor is also placed an elastic body such as a pad of rubber or
a spring, which prevents jar or shock should extra weight be put upon the thinest
part of the joist.
:
The joists may be of any length and are placed end to end, so that the feet of
two joists rest on the same pad of rubber; or instead of the rubber pad, the feet
of the joists may be recessed, and spiral springs placed in such recesses, said.
springs maintaining the feet clear of the ordinary floor.
The top of the joists are covered with a floor of hard pitch pine or other wood
suitable for forming a dancing floor.

I, MEDLEY HALL, of 29 Northgate, Halifax, in the County of York, Architect.
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 follow-
ing statement:-
This invention relates to improvements in the construction of floors of rooms
and buildings specially designed for dancing purposes, the object being to con-
struct a floor having a certain amount of spring or elasticity and the requisite

page_text: strength and stability. The improvements hereinafter 'described can be applied
to existing floors equally as well as to floors in the course of construction.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the annexed drawings, in
which:-
Fig. 1 is an end sectional elevation of part of a floor constructed and laid
according to this invention.
Fig. 2 is a detail of Fig. 1 drawn to an enlarged scale.
Fig. 3 is an end view of Fig. 2.
According to this invention a floor 1 is constructed and laid in the ordinary
manner and on or to this floor is applied the improved spring floor 2 constructed
as follows: Across the ordinary floor 1 are laid a series of joists 3 parallel to
one another and about the same distance apart as the joists of an ordinary floor,
and each joist 3 is concave on its underside 4 the outer ends 5 forming feet on
which the joists 3 rest, and between each foot 5 of cach joist 3 and the floor 1 is
placed a pad of rubber or other elastic body 6, and about the apex of the con-
cave portion 4 and between the same and the ordinary floor 1 is also placed an
elastic body such as a pad of rubber 7 or a spring which prevents jar or shock
should extra weight be put upon the thinest part of the joist 3.
The joists 3 may be of any length and are placed end to end so that the
feet 5-5 of two joists 3-3 rest on the same pad of rubber 6. Instead of the
rubber pad 6, the feet 5 of the joists 3, it will be obvious, may be recessed an
spiral springs placed in such recesses, said springs maintaining the feet 5 of
the joists 3 clear of the ordinary floor 1.
The top of the joists 3 are covered with a floor 2 of hard pitch pine or other
wood suitable for forming a dancing floor.
The ends of the joists 3 do not abut against the inside of the wall 9 of the
building or room but are kept clear of same so that the vibration of the floor 2
does not affect the walls. The curve or contour of the concave portion 4 may
be varied as desired, but I have found in practise that the curve shewn in the
drawings gives good results. In some cases it may be desirable to slightly curve
or cut away the ends of the joists 3. 3 as indicated by the dotted lines (see Fig. 2)
and the floor 2 would then, in a state of rest, be slightly convex, but when any
weight is placed about the centre of the joists 3, or when the floor has been laid
some time, the joists 3 give way slightly and the floor assumes a level or flat
position. It is not necessary that the ordinary floor 1 should be a complete floor
as the joists 10-10 of same provide a good and sufficient foundation for the im-
proved spring floor.
Fewer joists 10 than shewn by the drawings may be used, as it will be obvious
that the joists under the concave portions 4 of the joists 3 have little weight or
strain to bear and act only as ceiling joists.
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:
-
A floor, or part floor, laid on top of which are a series of hollow or concave
joists 3-3 with rubber or springs between such joists 3 and the floor 1, and a
floor 2 laid on top of the joists 3, as and for the purpose herein described and
substantially as illustrated by the accompanying drawings.
