Abstract: A modular door lock apparatus having a mainframe defined by a front face plate and an outer and inner side plate extending rearwardly of said front face plate a latch assembly being fixedly mounted to said front face plate, so as to be positioned between the side plates. A key cylinder is secured to the outer side plate and a latch knob is mounted to the inner side plate so as to operate the latch bolt of the latch assembly. The door lock apparatus is secured to the door by sliding the apparatus into a central bore and adjacent longitudinal slots that are formed in the leading edge of the door. The apparatus is then secured to the door by means of a pair of transversely positioned screws that are received through the oppositely disposed slots having their threaded ends extending outwardly of the outer side plate to engage the key cylinder. The screws may also be provided with nuts, which are fixedly positioned against the outer side plate.

Abstract: A price-marking stamp device adapted to be mounted to the molding positioned along the edge of a shelf having items stored thereon, whereby the consumer can individually mark the price of a selected item therefrom. The device comprises a main support body having a locking member to retain the device within the channel of the molding, and a movable ink-pad holder interconnected to the main support body by a ball-joint member, the ink-pad holder being arranged to removably receive various price-indicating ink pads, and the pad holder and ink pad being covered by a slidable housing which is spring-biased to normally receive and cover the ink pad, the ink pad having numerical indicator members disposed on the face thereof so as to be pressed against the selected item to be price-tagged, at which time the slidable housing is forceably retracted to expose the ink pad.
