Improvements in Joints or Hinges connected with Folding Bedsteads.
JOHN ANDERSON, Pottery Lane, Newcastle-on-Tyne, Engineer, do hereby declare
the nature of this invention to be as follows:-
This
This invention relates to folding frames for secret or cabinet beds, the length of
the frame is in three sections, the first or inner being fixed within the cabinet
and the next or middle part is attached to the first to fold upward, and the
outer part is hinged to it to fold down or under, and when extended the mattress
is attached to a cross bar within the cabinet and the outer end of the frame.
invention is the joint upon the first or fixed part and connecting the middle
frame to turn upward and so arranged that when the frame is extended the tension
line of the mattress is below the pivot of the joint thus holding it firm against
a suitable stop on the joint.

Improvements in Joints or Hinges connected with Folding Bedsteads.
I, JOHN ANDERSON, of Pottery Lane, Newcastle-on-Tyne, in the County of
Northumberland, Sawmill Engineer, do hereby declare the nature of this inven-
tion 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, folding frames for secret or cabinet bedsteads.
The frames of this class of bedstead are generally made in three sections, the
first or inner section being fixed within the cabinet. The next or middle section
is attached to the first in such a way that it is capable of being folded upwards
and the other section is hinged to the middle one in such a manner that it may
be folded down or under. When extended the mattress is attached to cross
bars fixed on opposite ends of the frame.
This invention refers to the joint for connecting the first and middle sections
of the frame.
And in order that my said invention may be better understood I will now
proceed to describe the same with reference to the drawing accompanying this
specification in which Fig. 1 shews the position of the joint when the bed is
extended: Fig. 2 shews its position when the bed is folded up.
The same letters denote the same parts in both the views.
A is the inner part of the mattress frame to be fixed within the cabinet. B is
the middle section of the frame and C the outer section. Referring to the

page_text: joint, A¹ is a plate fixed on to the part A of the frame. E is a bent lever pivotted
at B¹.
F is an arm screwed to the section B of the frame and jointed at C to the
bent lever E. K shews a three jointed hinge, attached to the ends of the
sections A and B as shewn. This hinge is provided in order to keep the two
sections A and B in line. J is a pin to act as a stop against which the free
end of the bent lever E rests when the section B is folded down as at Fig. 1.
D shews the tension line of the mattress when folded down as shewn at Fig. 1.
It will be seen that this line comes below the pivot C₁ of the joint thus holding
the free end of the lever E firmly against the stop J.
By constructing folding bedsteads according to my invention they may be
folded into the smallest possible space.
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:-
Connecting the first and middle sections of the frame of a folding bedstead
by a joint constructed substantially as and for the purposes set forth.
