Abstract
26,691. Weller, F. W., and Ash, Sons, & Co., C. Nov. 20. Mixing-valves; indicating - apparatus. - A hollow rotary valve for use in apparatus for administering one or more gases for producing anaesthesia &c. comprises a casing having separate admission ports b', c<1> for the two gases and a common delivery port d' and a valve e, preferably cylindrical, having two corresponding admission ports b<2>, c<2> leading through the valve to two triangular delivery ports formed by a diagonal separating partition e'. This arrangement ensures that the area of the delivery port d<1> available for one gas increases as the area for the other gas decreases and vice versa. An air-port f is provided in the casing for the administration of air only. The hollow rotary valve is secured in its casing by a sliding stop-plate k secured on the end of the valve by a clamping-screw l. In order to indicate readily the relative proportions of the gases passing, a dial g is provided with two scales graduated in opposite directions with pointers thereto projecting into a gap h<1> in a plate h turning with the valve.
