FILL CAP ASSEMBLY FOR SANDBLASTING MACHINES OR THE LIKE

摘要

The assembly includes a spring-loaded closure cap and attached stem reciprocatively mounted to a support carried internally of a pressurized tank. The support includes a pair of armsholding a slotted sleeve in register with the container fill aperture and in alignment with the stem. The stem is provided with a latch pin received by the slotted sleeve and the assembly may be held in an open position by depressing the closure cap sufficiently so that the pin clears the sleeve to permit the stem to be rotated to a latched position. In the closed position of the fill cap assembly, internal container pressure secures the seal. The closure cap is dome-shaped to facilitate the filling process and shield the working parts of the assembly.
