PROVISIONAL
SPECIFICATION.
An Improved Bed-lift.
1, HELEN GIBSON MONKHOUSE, Widow 32 Tulse Hill Brixton London S.W.
do hereby declare the nature of this invention to be as follows:-
It consists in a method whereby my improved bed-lift, Patent No. 7673 of
May 25th, 1888, may be so constructed as to be capable of adjustment to bedsteads
of varying size & construction. Thus, 1st, the rectangular framework with
movable straps, as now in use, may be so constructed that either or both of its side-
bars can be made to revolve. This is effected by passing the ends of the side-bars
If furnished with
through holes made to receive them in the adjustable end-bars.
either a worm & wheel screw, or a ratchet & pawl, the side-bar, with the moveable
straps secured to its side, can be made to revolve, and the straps are wound and
unwound so as to suit bedsteads of varying widths.
2ndly. I connect the uprights secured to the bedstead in two pairs, each pair
carrying longitudinally a bar, to which the lifting-bands are brought down and
made fast. Each bar is furnished with a worm & wheel screw, and by passing a
connecting-bar (with handle) through both these screws, and turning it, the bars
are turned and the lifting-frame, with the patient on it, is raised in a horizontal
position. The connecting-handle-bar may be made adjustable to the width of the
bedstead.

An Improved Bed-lift.
I, HELEN GIBSON MONKHOUSE, of 32 Tulse Hill, Brixton, London, Widow, 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:-
It consists in a method whereby my improved bed-lift Patent 7673 of May 25-
1888 may be so constructed as to be capable of adjustment to bedsteads of varying
size and construction. Thus 1st the rectangular framework with movable straps as
now in use, may be so constructed that either or both of its side bars can be made
to revolve. This is effected by passing the ends of the side bars through holes
made to receive them in the adjustable end bars. If furnished with either a worm
and wheel screw, or a ratchet and pawl, the side bar with the movable straps
secured to its side can be made to revolve and the straps are wound and unwound
so as to suit bedsteads of varying widths.
2ndly. I connect the uprights secured to the bedstead in two pairs, each pair
carrying longitudinally a bar to which the lifting bands are brought down and
made fast. Each bar is furnished with a worm and wheel screw, and, by passing a
connecting bar (with handle) through both these screws, and turning it, the bars
are turned and the lifting frame with the patient on it, is raised in a horizontal
position. The connecting handle-bar and end rails may be made adjustable to the
width of the bedstead.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1, Sheet 1, is an end elevation partly in section of a bedstead fitted with a
lift constructed according to my invention. Figures 1 and 2 Sheet 2 are a side
elevation and plan respectively of the same.
a a, b b, are four standards one of which is shewn separately in side and edge
elevation at Figures 9 and 10. These standards are secured to the bedstead by
straps c passing around bars d on them and the feet of a and a and of b and b are
also tied together by straps e eff are shafts (one of which is shown separately at
Figure 7) by which the barrels af on the standards a are connected to the barrels b¹
on the standards b.
The barrels a' a' have fixed to them worm wheels as a driven by worms gl g¹ on
the ends of a shaft g shown separately at Figure 8.
The barrels a' and 6' have cords h and i wound upon them which pass up over
pulleys a³ 63 at the top of the standards and are connected to the side bars k of the
rectangular frame. I are the straps connecting the bars k and upon which the
patient is supported. The methods of attaching the straps to the bar and of passing
the former under the patient are illustrated at Figures 2, 3 and 4 and being the
same as those described in my said former Specification require no further notice.
As shown in Figure 5 one (or it might be both) of the side bars k of the rectangular
frame is made to turn in the end bars m so as to shorten the straps and is prevented
from turning back again by the pawl n taking into the ratchet wheel o.
The end bars m are made adjustable in length, being in two parts, either sliding
one within the other and worked by a screw as shown in Figure 5 or sliding one
upon the other and secured by bands and set screws as shewn in Figures 6.
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. In bed lifts in which the patient is supported on straps attached to two
opposite sides of a frame making one or both of such sides free to turn and thereby
vary the length of the straps substantially as described.
2. A bed lift consisting of four movable standards each carrying a barrel for
lifting bands such barrels being so connected together that they are simultaneously
turned by a single handle substantially as described.
3. The combination of the standards a a b b, barrels a¹ a¹ b' b', worm wheels a² a²,
shafts ff and g, and worms g¹ g' substantially as described.
4. Bed lifts substantially as described and shewn in the drawings.
