Abstract

775,476. Pinch cocks. APPLEBY & IRELAND, Ltd. Feb. 9, 1955 [Feb. 11, 1954], No. 4093/54. Class 135. A laboratory clamp for flexible tubes consists of a body 11 with a passage 12 to receive the tube 24, a plunger 18 slidable in a bore which opens into the passage 12, and an eccentric 25 pivoted between lugs 16 and engaging the knurled head of a screw which is adjustably threaded in the plunger 18. The eccentric is actuated by a hand lever 23. The lower end of the plunger 18 has a cylindrical convex surface where it engages the tube 24. A mounting flange 13 is fitted to the base of the body 11.
