COMPLETE SPECIFICATION.
An Improved Combination Bed and Operating Table.
I, WILHELM WIEMER of Breiterweg, Magdeburg, Germany, Merchant, 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 a bed or lounge which by a single grasp of a handle or
other part may be doubled or folded up and in this position forms a table on which
patients may be operated upon. As distinguished from other means or furniture
for the like purposes the upholstered or padded bed is made in two parts connected
together by a hinge on which one part may be turned to come over the other
part.
The invention is shewn in the accompanying drawing in which
Fig. 1 is a side view of the combination bed and operating table in the unfolded
position for use as a bed.
Fig. 2 an underneath view of Fig. 1.
Figs. 3 and 4 respectively a side and an end view of the same in the doubled up
position for use as an operating table.
Figs. 5 and 6 are views of details.
A, B, are two parts each independently upholstered or padded and connected
together by a peculiar hinge consisting of two cross bands of leather or fabric or
other suitable material, the one a being firmly sewn on to the upper top edges of
the two parts A, B, and the other b, to the two upper side edges of the same parts,
further, over the whole length of both of said parts and over the band a are sewn
four bands c (Figs. 4, 6) which in the stretched or extended position when the
part B is turned down take into and come flush with the padding of the bed. In
order to securely guide the part B when being turned so that it shall always come
into the same position and also to firmly hold the two parts together when use is to.
be made of the operating table, whilst preventing undue pressure between the two
parts by reason of the weight of the patient, there are screwed to the bottom of
one end of the frame of part A two hinges d each having in its free leaf or plate
a hole for the reception of one of two rods e whilst to the frame of part B are
screwed similar hinges for the reception of the opposite ends of the rods e which
when the part B is being turned slide in the holes of the hinges d, f, and act as
guides and stays to prevent lateral displacement of said part. In the turned down
position the rods e come underneath the bed frame and the hinges d, f, take the
position shewn in Figs. 1, 2.
In changing the bed into an operating table, the part B is brought out of the
position of Fig. 1 into that of Figs. 3, 4, by simply turning it over on its hinge a, b.
In this movement the rods e which may be held fixed at one end in the holes of
hinges slide in the holes of hinges d said hinges d, f, then being drawn out of
their position shewn in Figs. 1, 2, into that of Figs. 3, 4, upon reaching which the
set screws in hinges d,f, are tightened up so as to fix the rods e and hold the
parts A, B, firmly together, and so as not to be further appreciably pressed together
by the weight of the patient. C are supports for the legs of the patient lying
upon the operating table. They may be adjusted as to height turned by their
supporting rods in rods e and fixed in these latter each by a set screw (not shewn).
Dis a foot step or foot rest for the surgeon or other operator and is displaceable
in guide brackets h inwards or outwards horizontally, Figs. 1, 2, shewing the same
pushed in underneath part A.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what 1
claim is
1. A folding bed which in the folded position is adapted for use as an operating
table and which comprises two upholstered or padded parts A, B, connected together
by a hinge attachment so that they may be turned upon one another, substantially
as described and shewn.
2. In the herein before described combination bed and operating table, two or
more rods e slideable in hinges fixed to parts A, B, and capable of being fixed in
said hinges by screws g, for the purpose of securely guiding the part B, when
being turned up and of rigidly fixing the same in connection with part A,
substantially as described and shewn.
Dated this 29th day of August 1895.
