The lower edge of this cop is reinforced :by n bend 15 held in place by s plurality of screws 16 which extend throu h the bond and through the cop end whic project inwordly, as shown, so that they may be engaged' within the bayonet slots 13.

Mounted within oep le is o cup-sheped member 17 which hos its lower end closed and adopted to seat upon o gasket 18 disposed upon the Hangs 12 At its upper portion thecup 17 is formed with en enn larged portion dening o shoulder 19 which is engageoble with the projecting ends of the screws 16 for preventing the cup from @coming disassocioted from the cop. spring which is locoted within the oep nnd which hos one end shutting against the closed end thereof and its other end cloutting against the closed end of the cup.
