COMPLETE SPECIFICATION.
An Improved Adjustable Head-rest for Bedsteads, Sofas, and
the like.
I, FRIEDRICH EDMUND JOHANNIS BRUHN, of 10 Strohhause, Hamburg, in the
Empire of Germany, Mechanician, 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 the invention hereinafter described in detail is an adjustable head-
rest for bedsteads, sofas, and other similar articles of furniture, the said head-rest
being.so contrived as to admit of being easily adjusted in any position to suit the
requirements of the moment. The accompanying drawing serves to illustrate the
object of this invention, the explanation of the figures being as follows:-
:-
Fig. 1 is a plan of a bedstead fitted with a head-rest according to my invention.
Fig. 2 is a vertical section of the same taken on the line x-x.
A frame a made of iron and serving to receive a cushion, pillow, or bolster, is
provided at its head, with two slits b, one on each side, and in each of these moves
a curved rack c. These racks are kept in their relative positions by means of
bolts d and d¹ and form together a firm frame. To the bolt d' are also attached,
one on each side of the frame a, two levers d' the lower end of these being pivoted
to lugs which are fixed to the frame a by means of rivets.
At the head of the bedstead there are fixed, immediately underneath the frame a,.
two bolts e on which are wound the helical parts of the springs f, by means of
which the curved racks c are pressed forward to the extreme right ends of the
slits in the frame a. The tension of the spring f produces a movement of the
racks c and the extent of this movement is limited by the guards g, g.
Attached to the frame a immediately in front of the levers 2, there is a flat-iron
frame i, bound with hoop-iron and revolving either on an axle / or on two pivots k.
Near the axle h are also fixed two pulleys l, l, which serve to receive the cords m, m,
fastened to the bolts d. These cords m then pass over two guide pulleys p p.
fitted to the frame a, running underneath and along the whole frame a so as to be
within convenient reach of the invalid. A similar arrangement of cord is made in
connection with the bolt d', with this difference, however, that the cord o is attached
to the bolt on one side only of the frame (which may be either on the right or
left hand side), and then passed on to the pulleys p₁ and p on the corresponding
side of the frame.
If the invalid wishes to lower the head-rest he has only to pull the cords m,.
which would bring down the rack c to the position required, the rectangular frame i
leaning against the bolt d'.
By pulling the cord o the bolt d', and with it the racks o are raised, and the
frame brought into a correspondingly higher position.
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 1
claim is :-
1. An adjustable head rest for bedsteads, sofas, and the like arranged in such
manner that the pulling of two cords placed one on each side, lowers such head
rest, while the pulling of another single cord placed upon one side only raises the
head-rest to any required position, substantially as shewn and described.

page_text: 2. An adjustable head rest for bedsteads, sofas, and similar articles of furniture,
arranged in such a way that by pulling two cords m, m, fitted on both sides of the
said head rest the latter is lowered, and by pulling a single cord running along
only one side of the head rest the latter is raised to any position required
substantially as shewn and described.
•
3. An adjustable head rest for bedsteads, sofas, and the like, consisting of a
frame formed by the racks c, levers, d, and bolts d, d', and fitted with cords m, m,
passing over the pulleys 1, 1, and fastened to the bolt d, and having a single cord o,
running along one side only and fastened to the bolt d', substantially as shewn and
described.
4. An adjustable head rest for bedsteads sofas, and the like, consisting essentially
of a frame i pivoted to a frame a and supported by the curved racks c and levers d
and, springs for normally retaining the curved racks in contact with the ends of
the slits b, cords running over pulleys for retracting the curved racks when the
head rest is to be lowered, and a cord passing over pulleys for pulling up the bell
cranks, and racks when the head rest is to be raised, substantially as shewn and
described.
