I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for "A NEW OR IMPROVED APPARATUS FOR
AIRING OR VENTILATING BEDS a communication to me from abroad by Konrad
Weinberger, Gentleman of Nuremberg, in the Kingdom of Bavaria, German
Empire, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
The object of this invention is to air or ventilate the bed clothes especially
during the time they are not in use generally in the day time and consists of an
apparatus which will be fully described hereafter which is placed between the
bedclothes say between the two mattresses thus allowing the air to circulate freely
between them, and is moved when the bed is to be used.
The construction of this apparatus can be greatly varied it will therefore be
sufficient here to show some of the principal modifications.
Fig 1 shows a side view of the apparatus and Fig 2 the same closed up consisting
of seven horseshoe formed rods a-g of different sizes all moveable on one axle o o¹
and connected with each other by belts nets or tresswork &c.
The modification shown in Figs 3 (sideview) and 4 (plan) is provided with two
horizontal axles A. B. placed over each other in the middle of the apparatus
Each axle is provided with a moveable bar viz: the axle A. with the bar a-b and
the axle B with the bar c-d both these bars being connected at their crossing points
with each other by pins. These are provided with belts nets &c on their top and
bottom.
Figs 5 (plan) and 6 (side elevation) represent a folding or fixed contrivance
consisting of a number of rectangular and crossed bars three horizontal a b c and
three vertical def joined at the crossings as before stated.
The modification shown in Fig 7 is formed in the same manner the bars a,-a
and b, ba in number according to the length of the bed are joined at their crossings
moveably or fast the ends being provided with the horseshoe shaped bars c-d, e-f
fastened by the pins A and B.

page_text: Figs 8 and 9 show modifications to be used for part of the bed only, for instance
the pillows or the feet. Here the bars are exchanged for draw bars A & B with
collapsible movement.
These draw bars (with bent ends cushioned on the inner sides) are connected to
levers the fulcrum rods db & d¹ b¹ are are connected to regulate the length as
well as width of the bed If the parts A and B are fastened to the head and foot
of the bed and the belt is pulled and the belts nets &c stretched at the same time
the parts A and B are pulled on the bed.
In Fig 10 (side elevation) and 11 (plan) the belts net or treswork are fastened to
rollers in the sides of the bed and provided with counter weights g enclosed at
the head and foot of the bed When it is used the belts nets or tresswork are
drawn out stretched and connected in the middle of the bed.
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
1st The apparatus, consisting of horseshoe shaped bars revolving on one axle
held in position by belts nets tresswork for airing beds &c as shown in
Figs 1 and 2.
2 The arrangement of folding horizontal bars pivoted at their crossing points as
shown in Figs 3 and 4.
3 The fixed or folding arrangement shown in rectangular form Figs 5 and 6 and
diagonal form Fig 7.
4 The arrangement for raising part of the bed consisting of draw bars A. B.
connected to levers b. 6¹ moving on coupled centre rods d¹ and thus raising the
bar c Figs 8. 9.
5 The arrangement for suspending the belts nets tresswork &c to the sides of the
bed by cords running over rollers balanced by counterweights Figs 10 and 11.
Dated this 16th day of March 1885.
