Abstract

271,369. Lewis, J. Jan. 27, 1927. Leakage, preventing; dashpots, applications of. -A manually actuated oscillating disc valve is provided with a rubbing collar packing device pressed more tightly against its seat as the valve is closed and with an atmospheric dash-pot arranged to permit a rapid action during the last portion of the closing movement. The valve discs 26, 27 have an interengaging projection and socket embraced by a slot 25 in an arm 24 mounted on a squared part 20 on the actuating spindle 19. The spindle has a flange 21 fitted with a fibre washer 2 housed in a recess 23 in a tubular member 12 screwed by a right-handed thread to an extension 9 on the main casing. The actuating handle 31 is mounted on a squared part 29 of the spindle and has projections 34 adapted to engage sockets in a member 28 engaging lefthanded threads on the member 12. The actuating handle is adjustably secured by a nut 37 having a flange provided with a series of slots one of which is engaged by a pin 40 screwed into the handle. The dash-pot comprises a plunger 42 provided with a L-shaped port 43 and pivoted by a bracket 41 to a fixed part of the apparatus. The cylinder 44 is bored out at 49 to provided a release passage and is coupled by links 46 to the actuating lever. Specification 251,786 is referred to.
