FREDERIC EDWARD MOHR of 5A London Street Paddington in the County of
Middlesex Maker of surgical and orthopaedic appliances, do hereby declare the nature
of this invention to be follows:-
My apparatus has for its object the easy raising of an invalid, by one attendant to
any required height and position, either horizontal, reclining, sitting or otherwise;
thereby not only facilitating the taking of meals, the use of the bed pan etc., but also
enabling the patient to choose that position, which gives the most comfort, without the
slightest exertion on his part; further allowing the casy change of bedding and
remaking or entire removal of the bed, in which case the lift can be used as couch
or chair.
The nature of the apparatus and its working will be understood from the following
description and accompanying drawing.
The apparatus is a skeleton frame made of iron, consisting of a base a, two
uprights b, and a canopy c, jointed together by various cross bars and brackets; and
also a lift d, intended to receive the patient.
Fitted to uprights b, is a windlass e, provided with two cogwheels, leverlock g, and
winchhandle h. Fastened to windlass e, ascend four cords, which on the top of
canopy c, pass over fixed pulleys i, from thence descend on the sides of the apparatus,
pass over moveable pulleys with spring hooks k, and return to canopy c, where they
are fixed.
Lift d, is attached to spring hooks k, by rings / 1, 2, 3, 4. The three divisions of
the lift d, viz. backrest d b, seat ds, and legrest d l, covered with strong cloth, upon
which the patient rests, are jointed together by hinges m, and n, and kept straight or
formed into angles at will, by levers o, and hinge spring stops p.
Levers o, extent from seat ds, to about half length of the backrest d b, to which they
are attached by straps q. Hinge spring stops p, are fixed under hinges n, which they
keep straight when open, and allow free movement when closed. Fig. 1. shows the
levers 0;
and backrest db, fixed close together, hinge spring stops p, opened, and spring
hooks k, connected to rings 4, therefore the lift d will raise horizontally by simply
turning winchhandle h.

page_text: In fig. 2 straps 7, are fastened at their ends, hinge spring stops p, half closed, and
spring hooks k, connected to rings 1. If now winchhandle 1, be turned, thus
winding up the cords, the backrest db, will ascend first, until the slack straps 7, and
cords, are tight, then the seat ds, will follow, whilst legrest dl, drops by its own
weight, sliding along the bed s, or floor on rollers t, fitted to its end.
Any other required position is effected by attaching spring hooks k, and straps q,
differently.
Leverlock Ir consists of two parts; the lower part catching every tooth of
cogwheel, ensures the stoppage of the lift in the position required; the upper part,
when lift d, is wanted to descend, is thrown hack as marked by dotted lines; if now
handle h, be turned a little forward, leverlock g, will disengage itself, and lift d, can
be freely descended; therefore one hand suffices to do all the work.

page_text: FREDERIC EDWARD MOHR of 5A London Street Paddington in the County of
Middlesex Maker of surgical and orthopaedic appliances, 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 :—
My apparatus has for its object the easy raising of an invalid, by one attendant, to any
required height and position, either horizontal, reclining, sitting or otherwise; thereby
not only facilitating the taking of meals, the use of the bed pan etc., but also enabling
the patient to choose that position which gives the most comfort without the slightest
exertion on his part; further allowing the easy change of bedding and remaking or
entire removal of the bed, in which case the lift can be used as couch or chair.
The nature of the apparatus and its working will be understood from the following
description and accompanying drawings.
Figures 1 and 4 are side views, Figure 2 back view and Figure 3 top view.
The apparatus is a skeleton frame made of iron, consisting of a base A, two uprights B
and a canopy C, jointed together by various crossbars and brackets; and also a lift D,
intended to receive the patient. Fitted to uprights B is a windlass E, provided with
two cogwheels F, leverlock G, and winchhandle H. Fastened to windlass E ascend
four cords, which on the top of canopy C, pass over fixed pulleys I, from thence
descend on the sides of the apparatus, pass over moveable pulleys K. with spring hooks
and return to canopy C where they are fixed. Links L 1, 2, 3, 4, serve to lengthen the
front cords. The 3 divisions of the lift D viz., backrest Db, scat D 8, and legrest D
covered with strong cloth, upon which the patient rests, are jointed together by
hinges M and N, and kept straight, or formed into angles, at will, by levers O, which
form double back, and hinge spring stops P.
Levers extend from seat Ds to about
half length of the backrest D, to which they are attached by straps Q. Hinge
spring stops P are fixed under hinges M, which they keep straight when closed and
allow free movement when open. Fig. 1 shews the levers O and backrest Db, fixed
close together, hinge spring stops P closed, and spring hooks R connected to links L1,
therefore the lift D will raise horizontally by turning winch handle H.
In Fig. 4. straps Q are fastened at their ends, hinge spring stops Phalf open, and
spring hooks R connected to links L4. If now winch handle H be turned, thus
winding up the cords, the backrest Db will ascend first, untill the slack straps Q and
the lengthened front cords are tight, then seat Ds will follow, whilst legrest Dl drops
by its own weight, sliding along the bed or floor on rollers S fitted to its end.
Any other position is effected by attaching spring hooks R and straps Q differently.
Leverlock G is partly double, or consisting of 2 parts; the lower part catching every
tooth of cogwheel F, ensures the stoppage of the lift in the position required; the
upper part, when lift D is wanted to descend, is thrown back, as
marked by
dotted lines; if now handle H be turned a little forward, leverlock G will disengage
itself by counterweight, and lift D can freely descend; therefore one hand suffices to
do all the work.

page_text: 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. In an apparatus for lifting invalids, the canopy with pulley arrangement, as
described with reference to the drawing.
2. In an apparatus for lifting invalids, the combination of windlass with attached
cords, which travel over pulleys.
3. The moveable pulley and chain arrangement for lengthening the cords in an
apparatus for lifting invalids.
4. The frame in 3 divisions with back lever or double back, hinged spring stops
and rollers, attached to the lifting apparatus for the purpose set forth as described and
shown in the drawing.
5. The self disengaging leverlock or catch of the apparatus in question.
6. The form of the apparatus as represented in the drawing.
