COMPLETE SPECIFICATION.
Improvements in Invalid Bedsteads.
I, GEORGE PARROTT, of Bicester, in the County of Oxfordshire, Carriage and Cab
Builder, 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 improvements in invalid bedsteads, the objects of which are,
Firstly, that the patient may be raised from a lying to a sitting posture without
vibration or moving the lower part of the body along the bed, and
Secondly, that the bed may be wheeled from place to place easily and with as little
vibration as possible to the patient.
In order that the invention may be more readily understood, I have hereto annexed
drawings illustrative thereof in which Figure 1 represents a side elevation of the bed in its
normal position, Figure 2 a similar side elevation with head of the bed elevated so as
to place the occupant in a sitting or reclining position, this Figure also illustrating the
provisions made for moving the bed from place to place. Figure 3 shews the method
of elevating the foot of the bed and Figure 4 is a back elevation of the head of the
bed illustrating features hereinafter fully described.
The same letters of reference relate to the same parts in the various views or
figures.
The frame A is supported upon the two rubber tyred wheels B. B. which revolve
independently upon the axle C. At the head of the bedstead are two permanent
legs D which being continued up form the arch E. At the foot of the bedstead are
two legs F pivoted midway so that they can be raised as shewn in Figure 2 for
the purpose of wheeling. To keep these legs in a vertical position for ordinary
use, there is attached to the frame A a chain and pin F1 (figure 1). The frame A
has mounted upon it small wheels upon which rests the upper frame A¹ A². The
upper frame AA" is hinged at the centre A" (figures 1, 2 and 3). The arch E
forms the bearing for the top of the screw E and the frame A forms the bottom
bearing of the screw E¹.
On the screw E runs the swivel E" (figure 2) fastened to that part of the upper
frame A¹¹
The screw E has fastened at the top a small handle E which when turned raises
the swivel E which raises with it that part of the upper frame A" which draws that
part of the upper frame A' along the lower frame A to the position shewn in Figure 2.
For the purpose of raising the feet of the patient if necessary the upper frame A¹ has
pivoted to it a ratchet bar which drops into teeth cut in the lower frame A
(figure 3).
Having thus 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. In an invalid bedstead the combination of a horizontal frame such as A and
a rolling hinged frame A¹ A" the portion A" of which can be raised or lowered
by means of a screw E', substantially as described and illustrated in the accompanying
drawings.
2. The combination in a bedstead such as described of a horizontal frame A having
permanent legs D and folding legs F with wheels B for facilitating the movement
thereof from place to place, substantially as described and illustrated in the
accompanying drawings.
3. The method of supporting the part A' of the bed in an elevated position by
means of a ratchet nivotted to the said
nart the free end of which ratchet takes

page_text: into one of a series of ratchet teeth formed on or attached to the frame A,
substantially as described and illustrated in the accompanying drawings.
4. The complete invalid bedstead constructed substantially as and for the purpose
herein described and illustrated in the accompanying drawings.
Dated this 30th day of July 1889.
