7536. Usher, L., and Trounce, H. S. April 10. Damping envelopes &c.-In a machine for affixing the stamps to and for closing envelopes, the envelope is fed between rollers B, B' on a belt A so that its closing-flap strikes the member C and, being depressed, has its gummed surface damped by a damper D. The envelope is carried forward between the rollers E, E', which serve to seal down the flap, and strikes against a projection on the wheel F, thereby turning its spindle and actuating the stamp-supplying mechanism. The latter comprises an upper roller G and a similar lower one, between which the stamps are fed from a reel H over a damping-pad I. The pressure of the envelope against a roller K causes a knife L to sever the stamp on the envelope, and the continued movement of the latter beneath - the roller K secures the stamp in place. The knife L acts on the edge of a slot in the side frame through which. the stamp passes. The dampers are fed from a reservoir R. The base-plate is extensible, and the rollers B<1>, E' are connected by a chain-drive or other gearing.
