Improved Means for Adjusting the Head Rests of Bedsteads,
Couches, Sofas, or the like.
FRIEDRICH EDMUND JOHANNIS BRUHN of 10 Strohbause, Hamburg in the
Empire of Germany, Machinist, 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 adjustable head-pieces for bedsteads couches sofas or
the like which can be raised or lowered and fixed in any desired position in a
very simple manner according to my present invention.
This invention is clearly illustrated in the accompanying drawings in which :-
Fig. 1 is a plan view of a bedstead provided with the improved headpiece.
Fig. 2 is a section on the line - Fig. 1.
Fig. 3 is a portion of the section shewn in Fig. 2, drawn to a larger scale, and
Fig. 4 is an elevation of the lever & toothed-rack arrangement shewn on a larger
scale-looking in the direction of the arrows y Fig. 2.
In the frame A (which may be of iron or other suitable material) at the head of
the bed where the pillows are supported an opening ax is provided in which a
toothed-rack a of curved form may work.
This rack also passes between two side pieces or cheeks b. b which are fixed upon
the frame A and is adapted to be raised to any desired position by means of the
toothed wheel d which is keyed or fixed on to the spindle c and is actuated by the
one-armed levert arranged beside it on the spindle or axis c.
On the spindle c¹ which carries the toothed wheel d' and on both sides of this
toothed wheel ratchet wheels e and fare cast or fixed with one of which fa pawl k
(pivotally mounted on the pin h which is fixed on the cheek 6) engages, whilst a
pawl fixed to the side of the lever t engages with the other ratchet wheel e.
means of these two pawls the toothed wheel d is prevented from rotating and
consequently.the toothed-rack a is prevented from sliding down.
By
A guard or cover or flap o which inay be made of bars or laths of iron or other
suitable material (between which wire netting is stretched) is hinged or pivotally
arranged on the frame A (for instance by means of the axis q journalled in the lugs
or mounts r) to receive the holster or pillows. This guard or cover o is directly
connected with the toothed rack a (by any suitable means such as hinges) and will
thus be raised or lowered, and with it the bolster and pillows, according to the
position of the rack a.
In order to render it impossible for the flap o to come in contact with the gearing
when the rack is allowed to slide down, the rack is provided with a stop a'.
So as to permit of the pawls k and being released from the two ratchet wheels
when desired, each of the said pawls k and is provided at the back with an eye or
shank m in which eye or shank a cord or chain 'n is fastened, by means of which the
pawls can be lifted whereupon the rack a is free to slide down.
If on the contrary it is desired to raise the head-piece and with it of course the
rack a it is only necessary to act upon the lever t by pulling on the cord n', which
is arranged on a guide pulley under the bed-stead or sofa and then carried to any
convenient point for instance over it as shown in the drawings so that in such case
the occupant of the bedstead or couch can raise or lower the head part or flap o as
desired

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 I declare that what I
claim is :-
1. An adjustable head-piece for bedsteads couches sofas and the like in which
the adjustment can be effected by the occupant of such bedstead etc. by means of a
lever such as t arranged underneath the bedstead or the like substantially as and
for the purpose set forth.
2. In an adjustable head-piece for bedsteads couches sofas or the like the com-
bination with a hinged or pivotted flap such as o of a toothed-rack such as a
attached to said flap a hinged lever such as t laterally arranged with respect to
said rack a and keyed or fixed to a spindle c' a pawl such a provided on said
levert adapted to engage in and rotate a toothed wheel such as e in one direction
and prevent its rotation in the opposite direction and means to impart motion from
said wheel to said rack a to raise and lower the flap o substantially in the manner
and for the purposes herein before set forth.
3. In an adjustable head-piece for bedsteads couches sofas or the like two pawls
such as k and in combination and acting in conjunction with ratchet wheels such
as e and made in one piece with a toothed wheel such as d' and cords or
connections such as n and n' arranged to act substantially in the manner and for
the purposes herein before set forth.
4. The improved means for adjusting the head-piece of bedsteads couches sofas
or the like arranged constructed combined and acting substantially in the manner
and for the purposes herein before described and illustrated in the drawing hereunto
annexed.
