There is a tube immediately above the heatingelement containing a sensitive volatile substancewhich contracts and expands with the slightestchange in temperature and provides a dependable ac-tion of ample power to actuate the control the heat reaches the proper temperature thecontrol turns off the current. When the temperaturefalls a few degrees the heat is turned on again. Sincethis action is automatic workmen need not watch the. The Wallace bench glue pot temperature and an increase in production is the di-rect result. The temperature gauge dial alwaysshows the heat attained and together with the jewel,set in the base casting, acts as a visible check on theheat maintained. The glue pot operates from any electric lightingcircuit and is put in operation by merely turning theswitch. The Wallace bench glue pot functions eitheras a water bath, hot air or dry heat pot and which1ever way it is used it can never overheat though thecurrent be left on over night. Th ere is a durable cast aluminum glue containersupported by special retainer lugs which preventfloating when the pot is but partly filled. The escapeof moisture is greatly minimized by this method ofsuspension. The base cover forms a dead air heatinsulator chamber between the heating unit and thebench, and the air gap which surrounds the heatingunit is further insulation between the heat unit and the base casting.
