synthesis of (chloromethyl)benzene

Just doing a past exam paper asking for a diagram of the apparatus for the synthesis of (chloromethyl)benzene, the starting compound being methylbenzene. Am fine with everything, except how to draw the bit where the gaseous chlorine comes in -- I assume that this would be through a delivery tube...possibly passing through one of those side tap funnel thingys which some pear shaped flasks have. Am sorry if I'm not making sense. Would appreciate any advice on what to draw.
yeah, basically a tube going into the oval flask, and Cl2 arrow going in.
