Abstract: A motile sign in which a human face mask is motivated up and down to indicate "yes" in answer to a question on the sign "Are we open?" and in which the mask is oscillated horizontally to indicate "No", The mechanism for operating the mask comprises a pitman drive which is movable to a vertical position to move the face mask up and down and to a horizontal position to oscillate the mask horizontally and wherein the mechanism and mask are fitted into a box shaped frame which is formed to provide a cowling about the mask and cooperates therewith to conduct cooling air being fanned by the mask into the box for cooling a small electrical motor which operates the drive mechanism.

Abstract: A vacuum molding apparatus of simplified construction utilizing a vacuum cleaner as a vacuum source. The molding apparatus includes a tray with upstanding side walls having upper outturned flanges for mounting a pair of horizontally positioned holder frames which clamp a sheet of thermoplastic material therebetween directly above a highly reflective, bottom surface of the tray which upon being heated uniformly heats the plastic sheet mounted parallel thereabove.The holder frames together with the sheet are manually transported and placed over a male mold pattern on a vacuum frame which comprises an air-tight box having a forominous top plate through which air is drawn beneath the heated plastic sheet which is draped over the plate, and the mold pattern thus forming the sheet about the mold pattern. The box has a vacuum chamber co-extensive with the perforated top plate which is connected to one end of a vacuum hose.
