Abstract
Abstract An angular casing of substantially V-shape comprising a pair of tubular arms joined at one end. One of said arms holding a compressed gas cartridge such that the frangible end portion of the cartridge is disposed near the juncture of the arms, and the other arm including a spring-loaded plunger held in the compressed position by a trigger mechanism. A pivotal striker is provided at the junction of the tubular arms, such that triggering of the plunger causes the striker to pivot against the frangible surface of the compressed gas cartridge to release the gas therefrom. The entire inflation device is adapted to be connected to, and communicate with, an inflatable bladder to form a circular life-preserving collar.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
61 words
An inflating device comprising an angular casing adapted to be connected between the ends of and communicate with an inflatable bladder, a compressed gas-holding means within said casing, a plunger disposed oN a spring within said casing, said spring adapted to be releasably held in compressed position, and a pivotal striker disposed between said plunger and said compressed gas holding means.
Claim 2
Dependent Claim
61 words
An inflating device comprising an angular casing adapted to be connected between the ends of and communicate with an inflatable bladder, a compressed gas-holding means within said casing, a plunger disposed oN a spring within said casing, said spring adapted to be releasably held in compressed position, and a pivotal striker disposed between said plunger and said compressed gas holding means.
Claim 3
Dependent Claim
101 words
An inflating device comprising a pair of tubular arms joined at one end to form a substantially V-shaped casing adapted to be connected between the ends of a longitudinally arcuate inflatable bladder, one of said arms including a compressed gas cartridge having a frangible surface portion, said other arm including a plunger disposed on a spring adapted to be held in the compressed position, pivotal striking means disposed at the juncture of said arms, said striking means adapted to be pivoted by said plunger to fracture said frangible surface of said gas cartridge to release said gas to inflate said bladder.
Claim 4
Dependent Claim
101 words
An inflating device comprising a pair of tubular arms joined at one end to form a substantially V-shaped casing adapted to be connected between the ends of a longitudinally arcuate inflatable bladder, one of said arms including a compressed gas cartridge having a frangible surface portion, said other arm including a plunger disposed on a spring adapted to be held in the compressed position, pivotal striking means disposed at the juncture of said arms, said striking means adapted to be pivoted by said plunger to fracture said frangible surface of said gas cartridge to release said gas to inflate said bladder.
Claim 5
Dependent Claim
23 words
The inflating device of claim 2 wherein one of said arms includes an internal collar for holding and positioning said compressed gas cartridge.
Claim 6
Dependent Claim
19 words
The inflating device of claim 2 wherein said plunger includes at least one channel through which gas may flow.
Claim 7
Dependent Claim
20 words
The inflating device of claim 2 wherein said casing is gastight except for a tubular connection with said inflatable bladder.
Claim 8
Dependent Claim
25 words
The inflating device of claim 5 including a ball valve in said tubular connection to prevent backflow of gas from said bladder into said casing.
Claim 9
Dependent Claim
108 words
An inflating device comprising a pair of tubular arms joined at an angle at one end to form a casing, cap means disposed on the unjoined ends of said arms, compressed gas-holding means positioned in one of said arms, spring means having a plunger disposed thereon disposed in said other arm, pin means extending through said casing adapted to hold said spring in the compressed position, trigger means connected to said pin means, pivotal striker means disposed at the angular junction of said arms whereby actuation of said trigger releases said spring causing said plunger to pivot said striker against said compressed gas-holding means to release said gas.
Claim 10
Dependent Claim
108 words
An inflating device comprising a pair of tubular arms joined at an angle at one end to form a casing, cap means disposed on the unjoined ends of said arms, compressed gas-holding means positioned in one of said arms, spring means having a plunger disposed thereon disposed in said other arm, pin means extending through said casing adapted to hold said spring in the compressed position, trigger means connected to said pin means, pivotal striker means disposed at the angular junction of said arms whereby actuation of said trigger releases said spring causing said plunger to pivot said striker against said compressed gas-holding means to release said gas.
Claim 11
Dependent Claim
27 words
The inflating device of claim 7 wherein one of said cap means includes a hook and the other of said cap means includes an outwardly extending neck.
Claim 12
Dependent Claim
69 words
The inflating device of claim 8 including a longitudinally arcuate inflatable bladder, said bladder having an eye portion near one end and a neck portion near its opposite end, whereby said inflation device and said bladder may be joined by connecting the hook of said inflation device and the eye of said bladder and by connecting the neck of said inflation device and the neck portion of said bladder.
Claim 13
Dependent Claim
25 words
The inflating device of claim 8 wherein said casing includes an outwardly extending wall around said trigger portion to protect said trigger from accidental actuation.
