Abstract: A pad printer device includes a base member (2), a table member mounted on the base member, a slide member (3) slidably mounted on the table member for movement between at least two positions, and a printing pad (17) supported on printing arm (16) mounted on a support block (15) slidably mounted in a box-like column (9) extending upwardly from base (1). Printing pad (17) is reciprocated vertically by lever-type arm (25) pivotally engaged (27, 28) with support block (15) so that operation of the arm reciprocates the printing pad vertically. An adjustable limit gauge device is mounted on slide block (15) and includes two separately operable set screws (30, 31) which separately engage with rotatable stop member (47) rotatably mounted on base member (1) for positioning thereof for engagement with the lower ends of the set screws.

Abstract: A self-inking pad has a reversible mechanism (3) for the print characters (4) arranged in a housing (2) and a metallic actuator yoke (7) slidably mounted on the housing (2), overlapping the same. The actuator yoke can be pressed down against the force of a return spring (9) in order to effect printing of the print characters, a handle (10) being arranged on the actuator yoke for that purpose. The handle is hollow, receives and supports an end (9a) of the return spring (9), whereas the other end (9b) of the return spring (9) is supported by a crosspiece (11) of the housing (2) and is surrounded by a sleeve (12) arranged on said crosspiece. When the actuator yoke is pressed down, the sleeve is pushed into the cavity of the handle (10). The sleeve is provided with at least one recess into which a sliding catch (17) arranged in a guide and linked to the actuator yoke (7) can be pushed in order to lock the actuator yoke in a determined position of its path of travel.

Abstract: An improved automatic contact ink stamping apparatus which is characterized by a multipart ink re-charging assembly which facilitates the changing of the supply of ink or the ink pad in a quick and easy manner without disturbing the fixed registration position between the ink assembly and the stamp mounting plate. The contact stamping apparatus disclosed in the type wherein the die stamp is reciprocated between an ink re-charging and a stamping position. The ink re-charging assembly includes a mounting bracket fixed to a support base of the apparatus which is conformed to removably receive an ink pad holder. The ink pad holder includes an ink pad which is positioned therein to engage the work surface of the die stamp when it is located in the re-charging position. The ink pad holder can be easily removed in a simple manner and replaced for any reason without removing and adjusting the registered and sealed initial position of the bracket relative to the die stamp.

Abstract: A hand operated stamp with two slidable housings, one inside the other, adapted to compress springs when slid together and also to rotate a stamp die from an ink pad contacting position inside the inner housing to an imprint positioin at the bottom of the inner housing. The compression springs are attached to and removable with a cap on the outer housing to save space and allow easy replacement of the ink pad.

Abstract: An automatic contact ink stamping assembly characterized by repetitive movement of the die stamping surface between inverted positions defining an ink supply and a printing position. The apparatus is characterized by a stamping die assembly pivotally mounted to a carrier block reciprocally driven by a piston and cylinder assembly between the ink supply and printing position. The die assembly is provided with an upstanding ear having a cam surface which engages a rotatably mounted wheel in a manner to cause the die assembly to pivot 180 degrees responsive to the stroke of the piston and to align the die stamping surface in an accurate position perpendicular to the axis of said piston in both the ink supply and printing position.

Abstract: An apparatus for marking an article has a frame within which a printing carriage is rotatably mounted. The carriage has two fulcrum assemblies which slide in channels on the frame. A drive mechanism moves the carriage from a marking position to a position where ink is applied to selected printing characters on the carriage. The carriage is moved to a third position where the fulcrum assemblies are released from the channels to rotate the carriage to facilitate changing the printing characters.

Abstract: A self-inking stamp comprises a base part (1), which contains an ink pad (2) that is opposite to the bottom surface of the base part, a stamp insert, which carries a printing plate (9) and is reciprocable between the ink pad (2) and the bottom surface and is adapted to be inserted at the same time, and an actuating member (3), which has two end legs (4), which are guided on the outside of the end walls (5) of the base part. The actuating member is displaceable toward the bottom surface of the base part against spring force. The ends of a pivot (10) of the stamp insert are movably mounted in the end legs (4) of the actuating member (3) and may be movably mounted in said end legs in slots which extend transversely to the direction in which the actuating member is displaceable. The stamp insert is provided at its ends with longitudinal tracks (14) for receiving respective guide pins (13).

Abstract: An automated contact ink stamping apparatus characterized by a vertical printing stroke wherein the stamping die surface is mounted to a single piston and cylinder assembly for vertical movement therewith between a stamping position on the down stroke and returned to an ink reservoir on the upstroke. The stamping die surface is carried on a pivot block which in turn is mounted to the end of the piston in a manner which inverts the printing surface of the stamping die through 180 degrees between an upper position to mate with the ink pad of the ink reservoir and an opposing position to stamp indicia on a workpiece. A cam surface is provided to guide the path of travel of the stamp pivot block in response to its pivotal connection to a cam follower engaging the cam surface.

Abstract: A pressure-actuated switch mounted in the handle of a self-inking stamper is actuated by a stationary plunger assembly which extends into the handle and pressures the switch when the stamp element is moved into contact with a surface being marked. Actuation of the switch advances a counting circuit remotely located inside the lid of a lockable box. A circuit times the stamp element in the stamping position to avoid multiple markings on a single count.

Abstract: A stamping device includes a stamp, with an inking pad or of the self-inking type, for printing or marking documents or objects, and a box, containing the stamp. The stamp is fixed on a part which retracts under a box cover and is mounted on the cover so that the cover is used as a single control member for moving the stamp into position for use and, after use, automatically retracting the stamp into the box. The part on which is fixed the stamp is slidably mounted on the cover by virtue of two grooves formed in the cover and into which extend engagement protrusions such as studs formed on the part.

Abstract: An improved self-inking hand stamping device comprises improved arrangements of parts of an encasing operating member relative to a frame member containing an invertible stamp carrying platen, and of an ink pad holder relative to the frame member and other parts inside the operating member; and a new construction of the ink pad holder enables clean and controlled inking of the ink pad in a holder kept in working position.
