Abstract

Apparatus adapted for charging portable gas-containing flasks adapted for use with spraying devices. The apparatus includes a compressor driven by an electric motor, the operation of the motor being initiated by a switch engaged by the flask when the flask is operatively mounted at the charging station of the apparatus. A pressure-operated switch is disposed in the motor circuit for shutting off the motor driving the compressor when the flask has been charged to the desired predetermined pressure. The apparatus is provided with a novel check valve which is disposed between the compressor and the flask-charging station. The apparatus has a split housing, the parts of the housing being secured together by means which also secures the motor and the compressor to the housing.

Claims

1. An apparatus for charging portable containers having at one end a hollow gas inlet port provided with a check valve permitting flow of gas only into the container, said apparatus comprising a container-charging station adapted to have the end of a container carrying the gas inlet port positioned thereon, a tubular outlet means fixedly connected to the charging station and positioned and dimensioned to slidably receive the gas inlet port and produce a gastight seal when the container is slid thereon, said tubular outlet means comprising a post having passage means for alignment with said check valve and elastic means for sealingly engaging said hollow inlet port of said container for a predetermined pressure, said elastic means engaging said hollow inlet port on each side of said check valve to preclude said container from being propelled from said post, gas-compressing means and a connection to the tubular outlet means, and means responsive to sliding a container into the charging station to initiate the gas-compressIng means, whereby when a container is slid on the charging station compressed gas passes through the tubular outlet and the gas inlet port of the container into the container only when the passage and check valve are aligned.

2. An apparatus according to claim 1 in which the gas-compressing means is driven by a motor and the means responsive to sliding a container on the charging station is a switch connected to start the motor.

3. An apparatus according to claim 1 in which the gas-compressing means is provided with a stopping means actuated when gas pressure into the container exceeds a predetermined amount.

4. An apparatus according to claim 2 in which the gas-compressing means is provided with a switch actuated by gas pressure to the container in excess of a predetermined amount, said switch stopping the motor.

5. An apparatus according to claim 2 in which the switch actuated by sliding a container on the charging station is a spring switch and opens under spring pressure when a charged container is slid off of the charging station.

6. An apparatus according to claim 4 in which the switch actuated by sliding a container on the charging station is a spring switch and opens under spring pressure when a charged container is slid off of the charging station.
