PROVISIONAL SPECIFICATION.
An Improved Folding Table.
JOHN CRAIG Joiner, Langbank, Portglasgow do hereby declare the nature of my
invention for AN IMPROVED FOLDING TABLE to be as follows:-
The object of this invention, is, the providing of a folding Table, which when
folded out can be used with as much ease and freedom as an ordinary four legged
Table, and when folded up goes into a compact small space, and is arranged as
follows;
Two crossbars are fixed to the underside of the top, one on each side, these form
the two side rails. The legs of the table are put together in the form of two frames
one for each end. The width of said frames being equal to the space between the
side rails.
At one end a bar is fixed to the underside of the top of the table, between the two
aforesaid side rails, to this bar, one of the aforesaid frames is hinged.
Two small fillets or cross-bars, are fixed, one on each of the aforesaid side rails, so
as to form checks for the aforesaid frame when folded out at that end, when folded
up the legs of this frame lie close to the top, at the opposite end of the Table. -
For hinging the frame at the other end of the Table a bar is fixed to the under-
side of the top of the table between the legs which are folded up, the depth of said
bar being the same as the thickness of the aforesaid legs. To the underside of this
bar, another bar is attached, by means of a pivot hinge, so as to admit of a swivel
motion, this bar runs the full length between the two side rails, and, works into a
grove which is formed for it in the side rails. To this swivel bar the frame is hinged
in such a position that it can be folded down on the top of the first frame.
One fillet or cross-bar is fixed to the side rail, at one side only, to form a check for
this frame when folded up.
-
To admit the frame which is lying underneath the swivel bar being folded out, the
swivel bar has to be turned round as far as clear the legs of the aforesaid frame, it is
then put into position again. The side at which there is no fillet or cross-bar for a
check, a slip-bolt or button is attached to the outside of the frame, and shuts into a
grove formed for it in the side rail. To hold these frames tight in there position
when folded out against the checks, two flaps or bars which run the full length
between the frames, are hinged to the underside of the top of the Table, one at each
side, and when said flaps or bars are folded out, they hold the frames securely in
there position.
When this Table is used for purposes such as an Officers Camp Table, which
requires stability coupled with lightness. A mettalic bolt is passed through the two
frames which form the legs and is secured by a nut on the outside, this binds the
whole Table together and makes it as riged and firm, as an ordinary fixed framed four
legged table.

An Improved Folding Table.
JOHN CRAIG Joiner Langbank Portglasgow 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 :-
The object of this invention, is the providing of a folding Table, which when
folded out, can be used with as much ease and freedom, as an ordinary fixed framed.
four legged Table, and is arranged as follows;
Two cross bars are fixed to the underside of the top, one on each side, these form
the two side rails.
The legs of the table, are put together in the form of two frames, one for each end,
the width of said frames, being equal to the space between the side rails.
At one end, a bar is fixed to the underside of the top of the table, betwen the
two aforesaid side rails, to this bar one of the aforesaid frames is hinged. Two small
fillets or cross-bars are fixed, one, on each of the aforesaid side rails, so as to form
checks, or stops for the aforesaid frame, when folded out at that end. When folded
up, the legs of this frame lie close to the top, at the opposite end of the Table.
For hinging the frame at the other end, a bar is fixed to the underside of the top
of the table, between the legs which are folded up, the depth of said bar, being the
same as the thickness of the aforesaid legs.
To the underside of this bar another bar is attached by means of a pivot hinge, so
as to admit of a swivel motion,. this bar runs the full length, between the two side
rails and works into a grove, formed for it in the side rails.
To this swivel bar, the frame is hinged in such a position, that it can be folded
down on the top of the first frame.
One fillet or cross-bar is fixed to the side rail, at one side only, to form a check for
this frame when folded up, at the other side a slip bolt, or button is attached to the
outside of the frame, and shuts into a grove formed for it in the side rail.
To hold these. frames tight in there position when folded out against the checks,
two flaps or bars which run the full length between the frames, are hinged to the
underside of the top of the table, one at each side, and when said flaps or bars are
folded out, they hold the frames securely in there' position.
To make this Table more durable as a Military Camp Table, for use in various
climates, or when used for any purpose, that requires stability coupled with lightness,
a mettallic bolt is passed through the frames, which form the legs, and is secured by
a nut on the outside. This binds the whole table together, and makes it as riged and
firm, as an ordinary fixed framed four legged Table.

Specification."
A. Side rails, to which the top is fixed.
B. Cross bar, fixed to the underside of the top, to which one of the frames, which
form the legs, is hinged, at one end.
C. Checks or stops, fixed across the aforesaid side rails, to which the frames which
form the legs fold out against.
D. Cross bar fixed to the underside of the top, to which the swivel bar is hinged by
means of a pivot hinge.
E. Swivel bar, to which the other frame is hinged, this bar admits the frame being
turned as shown on Drawing, to admit the frame which lies underneath it being
folded out.
F. Folding flaps or bars, hinged to the underside of the top, one on each side
when these flaps or bars are folded out between the two frames which form the legs
of the Table, they hold said frames tight against the checks or stops, C, which are
fixed to the side rails.

page_text: Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that what I
claim is;
1st. Pivot hinged swivel bar, to which one of the frames is hinged.
2nd. Hinged folding lacking flaps or bars, for secureing frames.
