Device for dispensation of compressed gas

A portable compressed gas dispensation device for use in conjunction with a small cylinder of compressed gas, said dispensation device comprising

• a support frame having a first cavity formed at the central portion of said frame and a second cavity formed in said frame below said central cavity;
• a cylinder punch assembly disposed in the top portion of said frame, said punch assembly extending from the top wall of said support frame to said central cavity and comprising an engagement arm and an engagement sleeve, said engagement arm including a knob and a downwardly-extending cylindrical portion, said cylindrical portion having a peripheral recession formed proximate to said knob and threads formed at its distal end, said engagement arm further including a needle integrally formed with and extending from its distal end, said needle providing means to puncture the cylinder of compressed gas used in conjunction with the present device, said engagement sleeve including a sleeve rim formed at its distal end to facilitate sealingly engagement of said sleeve with the top wall of said first cavity of said support frame, said sleeve further including sleeve threads formed in its inner wall adjacent to sleeve rim, said sleeve threads being complimentarily formed with the threads formed at the distal end of the engagement arm for threadedly attachment thereto, said sleeve still further including a slotted opening formed in the walls thereof above said sleeve threads, said opening providing communication means with the chamber formed in the top portion of said frame;
• an adjustable cylinder table disposed within said first cavity, said cylinder table comprising a substantially bowl-shaped member having an integrally constructed stem which extends through the bottom wall of said first central cavity to cylinder adjustment means, said stem being integrally constructed with said cylinder adjustment means, said cylinder adjustment means including a rotatable dial integrally constructed with a dial extension having a threaded outer wall, the threads of said dial extension being complimentary with the threads of an adjustment means engagement slot formed in the floor of said second cavity;
• cylinder adjustment means disposed within said second cavity and integrally constructed with said cylinder table;
• and
• a trigger-operated nozzle disposed to one side of said support frame, said nozzle communicating with the cylinder punch assembly by means of a horizontally-extending chamber formed within said support frame above said first cavity, said nozzle attaching to said support frame by means of a nozzle extension which snugly fits within said chamber, said nozzle including a trigger attached to a trigger tongue, said trigger tongue extending through a nozzle outlet when said trigger is closed, said trigger being slidably attached to horizontally-extending slots formed in the walls of said main body within a trigger cavity, said nozzle further including an extension-biased spring disposed within said trigger cavity at the rear of said trigger.
