Abstract: A fountain stamp includes a body having a connecting rod, a base plate pivotally connected to the connecting rod, an ink container detachably attached to the base plate. A torsion spring is mounted around an axle connecting the base plate and the connecting rod to provide resilience to the base plate. The ink container for storing ink also receives an ink pad and a stamping plate inside. The ink permeates through the ink pad and moistens a stamping surface of the stamping plate. The fountain stamp further includes a housing to receive the base plate and the stamping plate.

Abstract: An exposure apparatus for photoengraving stamps includes a light-proof cabinet having a flash light therein and a drawer adapted to be drawn out therefrom. A clamp is carried on the drawer for holding the stamp. The clamp includes a base fixed to the drawer and formed with a pair of parallel rails, a pair of opposed holders movable on the base along the parallel rails, and means for moving the holders along the parallel rails in opposite directions synchronously. Each of the holders is also provided with a lifter for lifting up the middle plank between the bars and a handle for operating the lifter. Therefore the stamp may be held between the planks just under the flash light when the holders are moved closer together and the middle planks are lifted by turning the handles.
