COMPLETE SPECIFICATION.
An Improved Carriage for the Transport of Beds for Invalids.
I, GUSTAV ALLZEIT of Königsberg i/Pr., Carriage Maker, 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 a carriage for transporting beds for invalids together
with the invalids lying therein. The peculiarity of this carriage consists essentially
in the fact that the said carriage is slipped or pushed in underneath the bed of the
invalid to be carried, the arrangement being such that by pressing upon a single
lever, two forks take under the outer edge of the bed, whilst the whole upper frame
of the carriage rises and holds the bedstead securely supported at four points in a
freely suspended manner, so that the bed can be lifted without shaking or jolting
and can be transported without any shock to the place of destination.
In the accompanying drawings which illustrate this invention;
Figure 1 is a view showing diagrammatically the improved carriage with
depressed upper frame.
Figure 2 is a view showing diagrammatically the carriage with raised upper
frame, and
Figures 3, 4 and 5 are views showing details of said carriage.
Throughout the views similar parts are marked with like letters of reference.
The underframe of the carriage consisting mainly of the suitably formed front
and rear portions a and b which are connected together by means of longitudinal
rods c, rests upon the three wheels d d'. These wheels are preferably fitted with
rubber tyres and run on ball bearings. For the purpose of rendering the movement
of the carriage more easy, ball bearings are also provided in the casings e e¹ so that
the wheels are capable of moving with ease in all directions after the manner of
furniture castors.
In order to enable the front wheel d to be arranged at a suitable spot, the arms f
are provided which are capable of keeping the bearing free. At the front portion a
and also at the rear portion 6 of the framing, there are further arranged casings g gl
which are rigidly connected by means of arms h h¹ with the bearing or frame of the
front wheel.
The movable upper frame consists essentially of the front part i and the rear
part k, the said parts being connected by means of the part which is made of a
forked shape on both sides. The front part i has fixed to it two pillar-like
supporting arms which are connected together at a suitable height by means of the
cross bar n.
The guide bolts o o' which are fixed to the front and rear portions ik respectively,
are inserted in a readily movable manner in the casings 9 g', so that the upper frame
which is adapted to be moved up and down by means of a lever mechanism herein-
after described-is securely guided thereby.
The movement of the upper frame is effected by means of the following
arrangement of levers :-To the front part i there is pivoted at the point pa
ever q. A small lever arm g' of the lever q is connected at the point with the
ower front part h of the lever s that is pivoted at the point . The lever t is
urther connected at the point r. This lever is carried to the rear frame of the
arriage where it terminates in forks. The two forks engage with a bent lever
evice which is pivoted to the upper part k at the points u u. The fork i engages
t the points v. The bolts a a¹ serve as a pivot for the lever w w¹.

page_text: For moving the two arms y which take under the outermost part of the
bedstead, there is employed a lever mechanism which is constrained to move with
the lever mechanism that serves for moving the upper frame. For this purpose
there is arranged on the bolts at a bent lever z z¹ which carries at one part a
roller and which bears at the proper time against a shoulder on a sliding
piece d (which is adapted to move in a guide ) and thereby forces said sliding
piece back. The said sliding piece is acted upon by a spring e2 which has the
tendency of drawing the said sliding piece constantly into the position shown by
Figure 4. On the shoulder of the sliding piece d2 there is pivoted at the point fa
pair of levers gg. These levers g² are connected at the points h2 to the suitably
bent or cranked levers y that are pivoted at the points . The hooks k² fixed to
the parts & serve to limit the movement of the levers y.
In order to bring the carriage into the position shown by Figure 2, a claw k
provided with a handle is arranged which takes around the cross bar n and thus
locks the lever q in its place.
If it be desired for example to transport the bed B to another place, the
carriage is pushed in underneath the bed, until the pillars mm are close up against
the front part 6, so that the lugs m2 which are intended to support the bed, are
situated exactly under the part 64. The carriage now assumes the position shown
by Figure 1. If now the lever g be pressed in the direction of the arrow, the
arm g of the lever q engaging in the point r the said lever will move the lever t in
the direction of the arrow, whilst the lever t is securely guided by the lever s. The
said lever t which acts in the points v upon the pair of bent levers and moves in the
direction of the arrow, will also and at the same time move with it the double
levers. As the double lever moves down with its roller z against the
shoulder 62, it will release the levers arms y which are actuated by the spring e³,
and which return into their position of rest and engage in the books k². Thus they
will, in their end position, be situated exactly under the outer frame 6 of the
bedstead. On further pressing the lever t in the direction of the arrow, the upper
frame will be moved upwards by means of the action of the lever mechanism w w
at the rear, and of the levers at the front of the carriage, until the claw k engages
with the cross bar n.
In this movement, the lugs m2 and also the outer parts y² of the parts y will have
engaged under the frame of the bed, and thus have moved the entire bedstead
gently in an upward direction, so that in the position shown by Figure 2, the bed
will be held freely supported or suspended.
Up till now, all jolting in raising the bed has been excluded by reason of the
secure operation of the lever mechanism, and as the wheels are shod with rubber
tyres, and also the entire rotary or rolling movement takes place in or on ball
bearings, all shaking that would be painful to the invalid is obviated. The frame
of the carriage can be constructed very lightly. Its length is about two-thirds that
of the bedstead, so as to provide for a secure and safe position of the bed. As the
wheels can be moved and shifted with the greatest ease in all directions, the
transport of the beds is considerably facilitated. By reason of the arrangement of
the levers, only a small power is required for lifting the bed. The front lever q
can be made, removable, so that when the carriage is folded together the said
lever q shall not occupy too much room, and in such a case the carriage may be
conveniently kept under the bed.
This carriage is specially adapted for use in hospitals, and it is no longer
necessary to shift the bed in a manner that is painful to the invalid.
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.) The improved carriage for transporting the beds of invalids, substantially as
hereinbefore described and illustrated by the accompanying drawing.
(2.) A carriage for transporting the beds of invalids, consisting essentially of an

page_text: upper frame and an under frame the former of which is adjustably mounted on the
latter by means of guides such as 9, o and g', o' and the latter supported by three
wheels mounted castor fashion, the said upper frame being adapted to be raised
and lowered by means of lever mechanism, substantially as and for the purpose
set forth.
(3.) In a carriage for transporting the beds of invalids, as specified in the
preceding claim, an apparatus for securely supporting the bed to be raised, along
both its longitudinal sides, consisting essentially of levers y y pivoted to the cross
piece k or to any other suitable part of the upper frame of the carriage, of a sliding
piece d to which the levers y y2 are movably jointed by means of links g² of the
bent lever carrying the roller 22 adapted to release the said sliding piece which
is on the raising of the upper frame thereby moved by the spring e in such a manner
that the levers y y' place themselves transversely to the length of the bed and thus
take under the longitudinal side portions 63 of the bed, whilst arms m² on the front
cross piece i of the upper frame of the bed take under the front part 6+ of the bed,
as and for the purpose set forth.
