Improvements in or relating to Inflated Rings, Pads, Cushions, and
the like.
A communication from PAUL HERZ, of 18, Wachsbleichegasse, Dresden, in the
Empire of Germany, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The object of this invention is a device whereby air-inflated rings, pads or
cushions may be directly attached to the edges of vessels, apparatus and the like,
of either round or angular shape in section.
The india-rubber air-bag or tube which is to form the air-cushion is at present
generally secured to a frame of wood or metal which is subsequently fitted on to the
article it is desired to provide with an air-cushion. This fitting operation however
is frequently found rather tedious and complicated, in addition to which it is
attended by the disadvantage that an air-cushion thus secured in place is liable to
become loose at the joints and must therefore be provided with apparatus for
compensating for the escape of air.
The object of this invention is so to form the india-rubber ring that it may be
applied to articles of any desired shape in section, the edges of the sheet of rubber
or the like to be connected for the purpose of forming the tube or bag being
turned down so as to form one or more folds, the contact surfaces being besides
covered over with mastic and the like. In this manner a ring or rib is formed
upon the inner wall of the air-tube or cushion of smaller diameter than the latter,
and when this ring is passed over the edge of the article to which the air-cushion
is to be applied, a telephone or ear-trumpet for example, the cushion manifests the
tendency to pass over the edge towards the centre as it takes no part in the
stretching to which its inner ring is subjected and retains its normal diameter
however the said ring may be extended to fit the edge of the article to be provided
with an air-cushion, the result being that the ring in question firmly adheres to the
edge of the said article while the body of the air cushion thoroughly and tightly
covers up the said edge. When an air cushion is to be formed by means of ready-
made hose the fitting-ring may be secured to the inner wall of the cushion by
means of mastic or the like with practically the same result. Of course in this
case the durability of the arrangement would be more doubtful as the likelihood of
its getting unfastened is greater.
The before mentioned rib instead of being formed on the inside of the ring
may be formed at some other part for example its upper or lower side and if
desired may be formed on other than air-inflated rings such for example as those
distended by water.

mprovements in or relating to Inflated Rings, Pads, Cushions, and
the like.
A communication from PAUL HERZ, of 18, Wachsbleichegasse, Dresden,
German Empire, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
1.I.M.E., do hereby declare the nature of this invention and in what manner the
[Price 6d.]

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement:-
The object of this invention is a device whereby air-inflated rings, pads or
cushions may be directly attached to the edges of vessels, apparatus and the like,
of either round or angular shape in section.
The indiarubber air-bag or tube which is to form the air-cushion is at present
generally secured to a frame of wood or metal, which is subsequently fitted on to
the article it is desired to provide with an air-cushion. This fitting operation
however is frequently found rather tedious and complicated in addition to which it
is attended by the disadvantage that an air-cushion, thus secured in place, is liable
to become loose at the joints and must therefore be provided with apparatus for
compensating for the escape of air.
The object of this invention is so to form the indiarubber ring that it may be
applied to articles of any desired shape in section, the edges of the sheet of rubber
or the like to be connected for the purpose of forming the tube or bag being
turned down so as to form one or more folds, the contact services being besides
covered over with mastic and the like. In this manner a ring or rib is formed
upon the inner wall of the air-tube or cushion, of smaller diameter than the latter
and when this ring is passed over the edge of the article to which the air-cushion
is to be applied, a telephone or ear-trumpet for example, the cushion manifests the
tendency to pass over the edge towards the centre as it takes no part in the
stretching to which its inner ring is subjected and retains its normal diameter
however the said ring may be extended to fit the edge of the article to be provided
with an air-cushion; the result being that the ring in question firmly adheres to
the edge of the said article, while the body of the air-cushion thoroughly and
tightly covers up the said edge. When an air-cushion is to be formed by incans
of ready-made hose the fitting-ring may be secured to the inner wall of the cushion
by means of mastic or the like with practically the same result. Of course in this
case the durability of the arrangement would be more doubtful as the likelihood of
its getting unfastened is greater.
The before mentioned ribs instead of being formed on the inside of the ring may
be formed at some other part for example its upper or lower side and if desired
may be formed on other than air-inflated rings such for example as those distended
by water.
In the accompanying drawing
Fig. 1 is a plan of an air-cushion a provided with an inner fitting-ring & and
Fig. 2 is a view half in elevation and half in section.
Fig. 3 is a similar view of a tube having the solid, turned down fitting-ring
integral with it, and
Fig. 4 shows the manner in which an air-cushion is applied to the car-trumpet of
a telephone, with the ring drawn over it.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is :-
1. The combination with an air-cushion or pad such as a of a rib such as b
substantially as and for the purpose described and illustrated in the accompanying
drawing.
2. The complete pad or cushion a 6 substantially as described and illustrated in
Figure 1.
