Abstract

333,087. Christiansen, H. Sept. 19, 1929. Pinch cocks.-A tube clamp or pinch cock more particularly for laboratory apparatus comprises a base portion 1 with upstanding sides 2 provided with inclined slots 8, a tongue 3 constituted by a portion of the base 1 bent backwardly to lie between the sides 2, and a slider 10 acting against the back of the tongue 3 to compress a flexible tube 11 interposed between the tongue and the base portion. The slider is provided with transverse lugs 9 engaging in the inclined slots 8, the ends of the lugs being bent to prevent the spreading of the sides 2. A bent-up portion of the slider forms a finger hold to facilitate the operation of the slider.
