Abstract

20,238. Baker, W. H. Sept. 16. Plug cocks.-A plug cock fitted with a lever lock, and applicable for use on pipes, such as gas-meter pipes, is shown in Figs. 1, 2, and 4. The plug 8 is secured to a cap 13 by screws 20 and projecting posts 19. The cap has a slotted keyhole 13<a> to receive a key 18, which straddles a slotted pin 25. The key wards are formed to free the tumblers 29 and then slide the two bolts 21 and engage with recesses in the casing. The reverse movement frees the bolts, and allows the plug to be operated.
