Abstract
Abstract A venting device for use in withdrawing fluids from kegs which is generally T-shaped having a center leg and crossarms, said center leg and crossarms having communicating passages formed therein. The lower portion of the center leg has a keyed head with outlet passages therein for engaging the keyed operating member of a valve. One crossarm has a gas source inlet nozzle and the other crossarm a safety vent. The crossarm is used as a handle for rotating the device to open and close the valve.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
196 words
A combined venting and keg tapping device for use with a valve on a keg, comprising a generally T-shaped member having a center leg and crossarms branching out from the upper end to the center leg, said member being formed with communicating passages in the center leg and crossarms which passages meet at the juncture of the center leg and crossarms, there being a substantially straight passage through said crossarms, means at the free end of one of the crossarms for providing an inlet to a gas pressure source, venting means at the free end of the other crossarm in direct communication with the gas introduced into the device through said inlet means through said substantially straight passage, said venting means set to open to vent the gas introduced through said inlet means when the pressure of said gas exceeds a predetermined limit, means at the lower end of the center leg for engaging a portion of the valve for opening and closing the valve as said device is rotated, and means also located at the lower end of said center arm providing an outlet passage for the gas introduced through said inlet into the keg.
Claim 2
Dependent Claim
196 words
A combined venting and keg tapping device for use with a valve on a keg, comprising a generally T-shaped member having a center leg and crossarms branching out from the upper end to the center leg, said member being formed with communicating passages in the center leg and crossarms which passages meet at the juncture of the center leg and crossarms, there being a substantially straight passage through said crossarms, means at the free end of one of the crossarms for providing an inlet to a gas pressure source, venting means at the free end of the other crossarm in direct communication with the gas introduced into the device through said inlet means through said substantially straight passage, said venting means set to open to vent the gas introduced through said inlet means when the pressure of said gas exceeds a predetermined limit, means at the lower end of the center leg for engaging a portion of the valve for opening and closing the valve as said device is rotated, and means also located at the lower end of said center arm providing an outlet passage for the gas introduced through said inlet into the keg.
Claim 3
Dependent Claim
65 words
A venting device as in claim 1 wherein said crossarm having said venting means is formed with at least one venting passage in the wall thereof, said venting means comprising a sealing plug located within said crossarm and means for normally holding said sealing plug in a position to close said venting passage until said sealing plug receives pressure in excess of a predetermined quantity.
Claim 4
Dependent Claim
56 words
A venting device as in claim 1 wherein said inlet means comprises a nozzle having an end exterior of said device to which a conduit from a gas pressure source is adapted to be attached and an outlet end portion interior of said crossarm, and a bladder attached to said outlet end portion of said nozzle.
Claim 5
Dependent Claim
33 words
A venting device as in claim 2 wherein said means for holding said sealing plug comprises a resilient biasing means and means for adjusting the biasing force provided by said resilient biasing means.
Claim 6
Dependent Claim
85 words
A venting device as in claim 3 wherein said adjusting means comprises a first plug, mating threads formed on said first plug and the inner wall of the crossarm to accept and hold said first plug, said first plug having a head formed on the interior face thereof, said sealing plug having a head on one face thereof which faces the head on said first plug, and said biasing means comprises a spring located between the opposing faces of said first and said sealing plugs.
Claim 7
Dependent Claim
56 words
A venting device as in claim 5 wherein said inlet means comprises a nozzle having an end exterior of said device to which a conduit from a gas pressure source is adapted to be attached and an outlet end portion interior of said crossarm, and a bladder attached to said outlet end portion of said nozzle.
