PROVISIONAL SPECIFICATION.
Improved Pneumatic Beds for Ships and General Domestic
Purposes.
I, SAMUEL DAWES Boot Manufacturer of 43 Horse Fair Rugeley in the
County of Stafford do hereby declare the nature of this invention to be as
follows:-
The materials required are as follows: First "bottons," made of either wood
or metal, which may be in one piece or sectional pieces, & which forms the base
of the pneumatic bed. Second india-rubber bladder or bladders, which are made,
either with strips of india-rubber (having numerous holes in to allow of inflation)
runing through bladder, or, in sectional bladders, with hole in center of bladder;
india-rubber bladders, inay be made all of india-rubber, or the bottom side of
"india-rubber insertion." Third, suitable solution. Fourth, sheet india-rubber of
necessary size.
Fifth strips of india-rubber, insertion or like material, which are
put together in the following manner. A thin coat of suitable solution put upon
one side of wooden or metal bottoms or sectional parts of bottom, also upon one
size of bladder, or bladders. If one size of bladder or bladders is made of "india-
rubber insertion," this is the side to be cemented, the two are then put together,
& firmly cemented together. The necks of bladders through which inflation is
made, may be in the most convenient part of bladder.
"Sheet indiarubber" is used for cementing over by means of solution, the center
holes of sectional bladders & over cavities from one bladder to another.
"Strips of india-rubber," or "insertion" or "like material" are used for
cementing to sides of wooden or metal bottoms & to sides of bladder or bladders,
also they are used in like manner round center holes of in sectional bladders &
bottoms.
In shipping beds a brass or iron bar, is affixed to the underside of sectional
bottoms, one side of center hole, to which is attached a suitable strap, so that each
two parts of sectional bottoms may be converted into a life-saving apparatus, by
simply thrusting the arms through the center holes & fastening the strap around
them.
And among many the following are some of the advantages, thoroughly sanitary,
requires no labour in "making."
Will support the heaviest of persons.
In case of damage by puncture, easily remidied.
In case of shipping beds, they are immediately converted into life saving
apparatuses.

SAMUEL DAWES 43 Horse Fair Rugeley Staffordshire Boot Manufacturer 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 the making of beds upon the pneumatic principle, and
aims to provide a substitute for the ordinary material as is used for beds, and
consists in the application of india rubber bladders to wooden or metal seats or
frames.
The drawings annexed fully and clearly represent the construction of my
invention.
Figure I represents section of bed composed of bladders having holes in centre.
A valve in each bladder is placed in the most convenient position for inflation &
deflation.
Figure II represents section of bed composed of bladders having perforated
divisions or partitions running through them. A valve in each bladder is placed
in the most convenient position for inflation & deflation.
Figure 3 is a plan of frame.
Figure 4 is a plan of I. R. bladder on frame.

secured by the solution C. The sides of the india rubber bladder are firmly secured
to edges of frame by pieces of volute D by the solution which prevents the india
rubber bladders from coming away when any pressure is brought to bear on the
bed, and E represents the cover over the inflated bladder or bladders. F in
drawing represents sheet of india rubber stretched over hole on top of bladder to
give support to cover.
All the parts being put together as described, and shown on drawings the bed is
then inflated at neck of bladder, after which it is ready for use. Volute is a
rubbered canvas.
The beds are converted into life saving apparatuses by fixing 2 rings or such like
arrangement to under side of frame through which a strap is passed whereby a
person can secure the bed to his person, and prevent his sinking under the surface
of the water.
Having now particularly described and ascertained the nature of my inven
tion, and in what manner the same is to be performed. I declare that what I
claim is
I. The securing of the underside and edges of india rubber bladders to frames,
which india rubber bladders are provided with necks & valves for the purpose of
inflation and deflation, take the place of the ordinary material as used for beds
substantially as described and illustrated.
II. The immediate adaptation of beds to life saving apparatuses in cases of
shipwreck.
