Abstract

466,425. Plug cocks. LOFMARK, G. B. Nov. 27, 1935, No. 32895. [Class 135] The tapered plug of a plug cock is held in a tightening position by a spring 41, Figs. 1 and 3, secured to the body of the cock at one end and engaging with the plug at the other end. This engagement is effected by means of a bayonet slot 42 in the end of the spring which in a certain position of the plug passes on being depressed over a pin 39 projecting radially from the stem 38 at the small end of the plug. The plug is then turned until a radial projection 45 at the large end of the plug enters into a recess 44 in the cock body which limits the normal operative movement of the plug between shoulders 43 under which conditions the spring 41 is always in engagement to keep the plug in position. The plug is readily removed for cleaning by slight axial movement and rotation beyond its normal limiting position until the spring 41 disengages from the pin 39 when the plug can be removed. The invention is shown in Figs. 10 and 11 applied to a three-way cock for liquid dispensing apparatus, peripheral passages 159-161 on the plug being adapted to provide communication between passages 156 and 157 in one position and passages 123 and 157 in another position, these positions being determined by a radial projection 171 against stops 172, 173 respectively. A third position in which the passages are closed is determined by a spring-catch 166 engaging projections 168, 170 on the plug body. The knob 164 must be released and depressed respectively to enable the catch 166 to pass these projections to move the plug from one extreme position to the other.
