Abstract
Abstract An inflatable signal device has a hollow adapter suitable to communicate with a control valve attached to a tank holding gas. Another hollow adapter is set in and connects with an inflatable balloon and with said tank adapter. A sealed member seats on and normally closes said another adapter, but is movable off said seat by flow of gas when said control valve is opened. The principal object of my invention is to provide a simplified mechanism having two adapters which may removably be joined to communicate with each other, one of which stays with a balloon whereby the latter may be filled with gas flowing from a supply tank through said adapter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
183 words
A balloon in combination with a supply adapter and a balloon adapter, said adapters being adapted to communicate with each other in position of use, said balloon adapter having an opening therethrough and a seat surrounding said opening, a movable sealer member normally resting on said seat thus closing said ballon adapter, and movable means normally holding said sealer member in closed position on said balloon adapter seat, said sealer member being adapted to be moved away from said seat by pressure of gas from said supply adapter and thus move said movable means and permit gas to enter said ballon, the latter having a neck, said ballon adapter being mounted in said neck and said sealer member being within said neck, said balloon adapter having a flange in contact with the interior of said neck, and having an opening therethrough, said balloon adapter having an extension extending from said flange in the direction of the balloon and having an opening therethrough communicating with the opening in said flange, and saod opening in said extension having a greater diameter then said flange opening.
Claim 2
Dependent Claim
183 words
A balloon in combination with a supply adapter and a balloon adapter, said adapters being adapted to communicate with each other in position of use, said balloon adapter having an opening therethrough and a seat surrounding said opening, a movable sealer member normally resting on said seat thus closing said ballon adapter, and movable means normally holding said sealer member in closed position on said balloon adapter seat, said sealer member being adapted to be moved away from said seat by pressure of gas from said supply adapter and thus move said movable means and permit gas to enter said ballon, the latter having a neck, said ballon adapter being mounted in said neck and said sealer member being within said neck, said balloon adapter having a flange in contact with the interior of said neck, and having an opening therethrough, said balloon adapter having an extension extending from said flange in the direction of the balloon and having an opening therethrough communicating with the opening in said flange, and saod opening in said extension having a greater diameter then said flange opening.
Claim 3
Dependent Claim
