PROVISIONAL SPECIFICATION.
Improvements in Bedsteads.
I, ALFRED EDWARD BINGEMANN of Glenholme, Hilltop Road, West Hampstead in
the County of Middlesex, Gentleman, do hereby declare the nature of this invention
to be as follows :-
This invention has for its object improvements in bedsteads.
It is found in some cases that elderly people suffer inconvenience from slipping down
when in bed unless their feet abut upon a foot board. To obviate this inconvenience
and to meet the want of a bedstead with an adjustable foot board I construct bedsteads
baving side rails which are tubular and telescopic and I provide for the elongation of
the bedstead by means of a screw placed centrally and in an horizontal position.
The screw is carried by the foot frame and it enters a tube connected with the head
frame and in the tube a nut is provided. Hence on turning the screw in one direction
the head and the foot frame are drawn towards each other whilst on turning the screw
in the contrary direction they are separated further apart. The mattrass or bed used
with this bedstead is such as to admit of a certain amount of compression in a longi-
tudinal direction. To fill the gap produced by extending the bedstead and which
occurs between the foot frame and the lathes supported by the side rails I provide
other somewhat stiff lathes attached to the foot rail and threaded between the lathes
on the side rails. In order to raise an invalid in bed I provide at the head end of
the bedstead a frame lying flat and connected by joints to the side rails. This frame
extends from the head of the bed for some distance down towards the foot and say at
a distance of two feet down from the head the frame is jointed to the side rails. The
frame is covered with webbing or like material and the bedding rests upon it. There
are also two toothed ares which project downwards from this frame one on either side

page_text: and these engage with two pinions on a transverse horizontal axis carried by the side
rails. The axis at one end receives a handle and by this it can be turned. The
pinions gearing with the toothed arcs then raise them together with the rest of the
frame and the bedding supported thereon. There is a ratchet on the axis of tho
pinions and a pawl engaging with the teeth of the ratchet holds the axis in any
position to which it may be raised. Thus the patient on the bed may be propt up
and placed to recline at any desired angle. After raising and releasing the pawl the
frame may be lowered either right down or to any inclination which may be desired.

and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has for its object improvements in bedsteads.
It is found in some cases that elderly people suffer inconvenience from slipping
down when in bed unless their feet abut upon a foot board. To obviate this incon-
venience and to meet the want of a bedstead with an adjustable foot board I construct
bedsteads having side rails which are telescopic and I provide for the elongation of
the bedstead by means of a screw placed centrally and in an horizontal position. The
screw is carried by the foot frame and it enters a tube connected with the head frame
and serving as a nut. Hence on turning the screw in one direction the head and the
foot frame are drawn towards each other whilst on turning the screw in the contrary
direction they are separated further apart. The mattrass or bed used with this bed-
stead is such as to admit of a certain amount of compression in a longitudinal
direction. To fill the gap produced by extending the bedstead and which occurs
between the foot frame and the lathes supported by the side rails I provide other some-
what stiff lathes attached to the foot rail and threaded between the lathes on the side
rails. In order to raise an invalid in bed I provide at the head end of the bedstead
a frame lying flat and connected by joints to the side rails. This frame extends from
the head of the bed for some distance down towards the foot and say at a distance of
two feet down from the head the frame is jointed to the side rails. The frame is
covered with webbing or like material and the bedding rests upon it. There are
also two toothed arcs which project downwards from this frame one on either side and
these engage with two pinions on a transverse horizontal axis carried by the side rails
The axis at one end receives a handle and by this it can be turned. The pinions
gearing with the toothed ares then raise them together with the rest of the frame and
the bedding supported thereon. There is a ratchet on the axis of the pinions and a
pawl engaging with the teeth of the ratchet holds the axis in any position to which it
inay be raised. Thus the patient on the bed may be propped up and placed to
recline at any desired angle. After raising and releasing the pawl the frame may be
lowered either right down or to any inclination which may be desired.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan and Figure 2 is a longitudinal section of a bedstead constructed
in accordance with my invention.
Figure 3 is a section on the line 3. 3. in Figure 1.
aa aa are the corner posts, b is an angle iron rail connecting the two posts at the
head of the bed, cone joints of the ordinary sort being provided. c is an angle iron
rail which in like manner connects the posts a a at the foot of the bed.
The rails b and c have studs upon them to receive iron lathes.
dd are angle iron side rails connected by cone joints with the posts at the head of
the bed; they do not extend to the foot of the bed but here other angle iron side
frames e e are in like manner fixed. The frames e e pass within and beneath the
frames d d and blocks d' d' shown in Figure 3 fixed at intervals to the rails d serve
to keep the rails e in place. f is an angle iron rail connected by cone joints with the
extremities of the side rails d d. g is a tubular nut, it is fixed upon the rail which
by the side rails d d is connected with the head frame of the bedstead. is a screw
working in the tubular nut g and it is carried by a collar or bearing fixed upon the
angle iron rail c at the foot of the bed; by turning this screw by means of a loose
handle provided for the purpose the length of the bedstead can be adjusted. iii are
longitudinal and transverse lathes distended in the usual way between the rails bd d
and f. k kare other stiffer lathes attached to the rail c and interlaced with the lathes i i
as shown. is an adjustable frame provided with lathes 11 and jointed to the angle
iron side rails d d. mm are toothed arcs attached to the frame 1. n¹ n¹ are pinions
on an axis n they engage with the arcs m m and the side rails d d carry the axis. The
axis n is turned by a handle applied at its end. n³ is a ratchet on the axis n and n³ is
a pawl engaging with the same.
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 :-
1. A bedstead with telescopic side rails and screw carried by the foot frame such
screw engaging with a nut on the parts connected with the head frame substantially
as described.
2. A bedstead with side rails each in two parts one jointed to the head frame and
the other to the foot frame such parts being able to slide the one on the other and the
parts connected with the head frame being at their further extremities also jointed to
a cross rail substantially as described.
3. A bedstead having telescopic side rails and at the head end an additional frame
with toothed arcs and jointed at either side to the side rails, such side rails also carrying
an axis with pinions gearing with the arcs for the purpose of raising and inclining the
additional frame substantially as described.
4. A bedstead substantially as described and illustrated by the annexed drawings.
