Title: Improvements relating to machines for attaching adhesive postage stamps and the like
IPC: B65C11/04
Filed: 1926-05-06
Abstract: 275,338. Ryper, G. H. May 6, 1926. Affixing stamps.-In a machine for detaching from a strip and affixing postage stamps &c. to letters, cards and the like, means are provided for moistening the stamp only immediately prior to the affixing, so that when the machine is stopped, no stamp shall be left on the strip partially moistened. Cams 4, 5, 6 are carried by a shaft 3 which is adapted to be turned through a complete revolution by the actuation of a handle 9. The cam 4 rocks a shaft 11 rigidly fixed to a cranked lever 12. The lever 12 carries at its lower end an arm 19 on one element of a free wheel clutch, the other clutch element being a stamp feed roll 20. The cam 5 actuates levers 30 and a bell-crank lever 31 which are looselv mounted on the shaft 11. The levers 30 engage an affixing plunger 32 which is formed with a perforated face 33 and is normally positioned above a slab 34 from which the stamp strip emerges from the casing. The plunger 32 is hollow and houses a suction plunger 35 which is surrounded by a cup leather 36. The cam 6 actuates a lever 13 loosely mounted on the shaft 11 and carrying a pivoted arm 14 which has at its lower end a plate 15 and damping pad 16. The arm 14 and the lever 12 are connected by a pivoted link 17. A detachable water reservoir 37 fixed to the frame and closed at its lower end by an absorbent pad 39 is formed with a chamber 39<a> connected with a central pump chamber 43. Water can pass from the reservoir 37 to the chamber 39<a> through a grooved plug 40 controlled by a ball valve 42. The lower end of the chamber 43 is closed by a ball valve 44. A spring-returned pump piston 45 is operated by an arm 13a on the lever 13 to pass the water in the chamber 43 through the valve 44 to the pad 39, the upward stroke of the piston opening the feed-valve 42. The roll of stamps is carried in a hinged two-part casing formed with guide lips cut away to accommodate the feed roller 20. An upper feed roller 55 is carried on a hinged rocking arm 56 and can be raised to an inoperative position by a knob outside the casing. The feed of the strip is controlled by a cam 60 limiting, bv a screwed collar, the movement of the arm 19. In operation, the cam 6 rocks the lever 13 to lower the pads 16 from contact with the pad 39, the cam 4 then swinging the pad 16 under the stamp to be stamped. The pad 16 is then raised to damp the stamp by the cam 6. During this operation, the cam 5 begins to lift the piston 36 to apply suction to the upper face of the stamp to prevent its dislodgement when the pad 16 is returned to the pad 39 by the cam 4. The cam 5 then rocks the lever 30 to operate the plunger 32 which shears the stamp from the strip against a plate and affixes it to the letter, which is carried by an adjustable table. The suction through the holes in the perforated face 33 is continued through the shearing process.
