An Improved Inflating Valve for Life Saving Apparatus and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
In the inflation of life saving apparatus, in which the inflation often has to
be effected in a great hurry and in some cases even when the person in danger
is already in the water it is a matter of the greatest importance that none of the
inflating air be lost, either during the inflation or during the time occupied in
taking breath, so that the volume of air contained in the apparatus is augmented
as efficiently and as fast as possible in order that the person to whom the apparatus
is attached shall be able to float and thus be saved from drowning.
The object of this invention is to provide an inflating valve, by the aid of
which the inflation of a life saving apparatus (belt, buoy or the like) may be
effected with the greatest despatch and without any loss of the air. The valve
consists of two cylindrical parts or tubes which are movable in relation to each
other, viz. a fixed tube opening into the air container or connected with the same
and an upper movable part, (the mouthpiece) consisting of one cylindrical part
embracing the upper part of the fixed tube and another inturned cylindrical
part firmly connected with the said embracing cylindrical part and forming the
proper air tube. This mouthpiece can be moved at will for a certain space along
the fixed tube, this latter being at its inner side provided with a collar serving
as guide for the air tube of the mouth piece. This air tube is at its interior end
provided with openings through which the air can be inflated, but the interior
end of the air tube is closed by a bottom plate to the inner side of which is
fastened a washer of rubber or the like destined to contact with the collar of the
fixed tube when the valve is closed. This washer does not fill the fixed tube, but
between the edge of the same and the inner walls of the said tube there is left an
open passage through which the air can pass. To the bottom plate of the air tube
on the inner side of the washer there is fastened a valve plate of about the
same size as the washer, but preferably furnished with projections or ribs in
contact with the inner walls of the fixed tube. Inside of this valve plate is
fastened an elastic disc the edges of which are in contact with the inner walls
of the fixed tube. The washer as well as the valve plate and the elastic disc
may all be fastened to the bottom plate by aid of a pin screw or the like.
Between the air tube and the part of the fixed tube lying outside of the collar
of the same there is placed a spiral spring surrounding the air tube, one end of
which spring is fastened to the wall of the cylindrical part of the mouth piece
embracing the upper part of the fixed tube, and the other end of which is
fastened to the collar of the said fixed tube.

page_text: The fixed tube may suitably be provided with a pin working in a slot curved
at both ends and arranged in the mouth piece, by the aid of which pin and slot
the fixed and the movable part of the valve may be held in place in open as well
as in closed position.
The inflating valve acts in the following manner;
It is opened through pressing the mouthpiece downward (inward) in the
direction towards the collar of the fixed tube. The spiral spring is hereby com-
pressed and the washer unseated. When the open position of the valve is reached
the pin of the fixed tube moves into the curved inner part of the slot in the
mouth piece, whereby the valve is locked in its open position.
The valve being in this way opened, air is inflated through the air tube and
passes from this tube through the side openings of the same into the part of the
fixed tube lying within the collar. From here it passes through the passage
between the washer and valve plate on one side and the inner wall of the fixed
tube on the other and, exerting a pressure on the peripheral parts of the elastic
disc, forces these to yield, thereby gaining admittance to the air container of
the life saving apparatus.
As soon as the pressure of the air ceases the peripheral part of the elastic disc
instantly springs back into its former position thereby preventing the air from
passing back through the air tube.
When there has been inflated a sufficient quantity of air the valve is locked so
that the mouth piece is moved outward in the direction from the collar of the
fixed tube, and the spiral spring is released and carries the valve back to its
locked position.
In this locked position there is a double lock against the exit of the air, the
elastic disc forming one lock and the washer, which is in this position firmly
seated against the collar of the fixed tube, forming the other lock. The valve
is a double valve, which when in use is locked between each inflation by aid of
the elastic disc, and when in locked condition is provided with an additional lock
furnished by the washer being pressed against the said collar.

An Improved Inflating Valve for Life Saving Apparatus and the like..
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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;
-
In the inflation of life saving apparatus, in which the inflation often has to
be effected in a great hurry and in some cases even when the person in danger
is already in the water it is a matter of the greatest importance that none of the
inflating air be lost, either during the inflation or during the time occupied in
taking breath, so that the volume of air contained in the apparatus is augmented
as efficiently and as fast as possible in order that the person to whom the apparatus
is attached shall be able to float and thus be saved from drowning.
The object of this invention is to provide an inflating valve, by the aid of
which the inflation of a life saving apparatus (belt, buoy or the like) may be
effected with the greatest despatch and without any loss of the air.

page_text: the accompanying drawing,
Figure 1 shows a section through the mouthpiece, when it is open.
Figure 2 shows a side elevation, when it is closed, and
Figure 3 shows a detail.
The valve consists of two cylindrical parts or tubes which are movable in
relation to each other, viz. a fixed tube B opening into the air container or con-
nected with the same and an upper movable part AC (the mouthpiece) consisting of
one cylindrical part C embracing the upper part of the fixed tube and another
inturned cylindrical part A firmly connected with the said embracing cylindrical
part and forming the proper air tube. This mouthpiece can be moved at will
for a certain space along the fixed tube, this latter being at its inner side pro-
wvided with a collar P serving as guide for the air tube of the mouth piece.
This air tube is at its interior end provided with opening F through which the
air can be forced, but the interior end of the air tube is closed by a bottom plate
to the inner side of which is fastened a washer I of rubber or the like destined to
contact with the collar of the fixed tube when the valve is closed. This washer
does not fill the fixed tube, but between the edge of the same and the inner walls
of the said tube there is left an open passage through which the air can pass.
To the bottom plate of the air tube on the inner side of the washer there is
fastened a valve plate H of about the same size as the washer, but preferably
furnished with projections or ribs in contact with the inner walls of the fixed
tube. Inside of this valve plate is fastened an elastic disc K the edges of which
are in contact with the inner walls of the fixed tube. The washer as well as
the valve plate and the elastic disc may all be fastened to the bottom plate by
aid of a screw pin G, or the like.
Between the air tube A and the part of the fixed tube lying outside of the
collar of the same there is placed a spiral spring Q surrounding the air tube,
one end of which is fastened to the wall of the cylindrical part of the mouth
piece C embracing the upper part of the fixed tube, and the other end of which
is fastened to the collar P of the said fixed tube.
y is a lug or projection which may be fastened on the upper part of mouth-
piece in any convenient manner & which serves as a hold for the fingers when
turning the said part of the mouthpiece.
The fixed tube B may suitably be provided with a pin U working in a slot T
curved at both ends and arranged in the mouth piece, by the aid of which pin U
and slot T the fixed and the movable part of the valve may be held in place in
open as well as in closed position.
The inflating valve acts in the following manner;
It is opened through pressing the mouthpiece A C downward (inward) in the
direction towards the collar P of the fixed tube B. The spiral spring Q is hereby
compressed and the washer I unseated. When the open position of the valve is
reached the pin U of the fixed tube moves into the curved inner part of the slot T
in the mouth piece, whereby the valve is locked in its open position.
The valve being in this way opened, air is inflated through the air tube and
passes from this tube through the side openings F of the same into the part of the
fixed tube lying within the collar. From there it passes through the passage
between the washer I and valve plate H on one side and the inner wall of the
fixed tube B on the other and, exerting a pressure on the peripheral parts of
the elastic disc K, forces these to yield, thereby gaining admittance to the air
container of the life saving apparatus.
As soon as the pressure of the air ceases the peripheral part of the elastic
disc K instantly springs back into its former position thereby preventing the air
from passing back through the air tube.
When there has been inflated a sufficient quantity of air the valve is locked
so that the mouth piece is moved outward in the direction from the collar of the
fixed tube, and the spiral spring Q is released and carries the valve back to its
locked position.

page_text: In this locked position there is a double lock against the exit of the air; the
elastic disc K forming one lock and the washer I which is in this position firmly
seated against the collar of the fixed tube, forming the other lock. The valve
is a double valve, which when in use is locked between each inflation by aid of
the elastic disc K and when in locked condition is provided with an additional
lock furnished by the washer I being pressed against the said collar P.
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. A mouthpiece for inflation of life saving apparatus or the like consisting
of parts sliding into each other and provided with a double valve, which opens
inwardly and one part of which serves during the inflation to shut off the air
after each breath whereas the other is locked in the closed position when the
inflation is closed by suitable means.
2. A mouthpiece for inflation of life saving apparatus of the character described
under Claim in which the preliminary shutting off after each inflation is
effected by an elastic plate capable of only bending inwards, the mouthpiece,
when it is closed, being shut off by a collar, said plate being locked in its closed
position by a spiral spring, the mouthpiece consisting of two parts sliding within
one another, one of said parts being a double cylinder with an inner casing
carrying on its lower end both the above mentioned elastic plate and the packing
plate, whereas the other part carries the collar on which the packing plate rests,
when the valve is closed, the above mentioned spiral spring with its upper end
fastened to the former and its lower end to the latter of the two above mentioned
parts.
3. In a mouthpiece of the kind under Claim 1 described the arrangement, of a
stop (U) fastened to the lower main part of the mouthpiece (B) moving in a
slot (T) on the outer cylinder (C) of the double cylinder forming the upper
part of the mouthpiece, said slot (1) being provided at the top and bottom with
lateral extensions into which the stop can be pressed by a spiral spring fastened
both to the main part (B) and to the double cylinder (A C).
