Abstract: A stamping apparatus for a heat requiring ink is described wherein a stamping head is moved between an ink wetting position and an object stamping position. A stamping pad is located in a heated housing wherein a replaceable stamping pad is mounted on a rotatable spindle and wherein a metal heated casing at least partially surrounds the stamping pad to heat the ink on the stamping pad to a workable temperature. The stamping head normally is resting against the heated stamping pad to also receive heat from the metal casing and thus be able to transfer ink from the head seated against the pad to the object to be stamped. Heat from the heater in the metal casing is also transfered to a chamber where a reserve stamping pad can be stored to be preheated and thus ready for instant use when needed. A resilient pin is employed to move the rotatable stamping pad as the stamping head leaves its wetting position for stamping of an object.

Abstract: A printing apparatus employs a rotatable cam having an enclosed cam slot for controlling the rocking motion of an inking roll without the need for a cam follower spring. The apparatus also includes an articulated printing member support assembly which executes a complex curvilinear movement under the control of a fixed cam slot without the use of linear bearings. Complementary cam profiles are used on both cam surfaces in order to maintain tangency between the inking roll and printing element during inking. A yieldable connecting link is used to prevent excessive printing pressures from being applied, and a movable filler plate closes off a slot in a front cover of the printing apparatus through which a portion of the movable printing member protrudes.

Abstract: A print head assembly for intermittently marking surfaces, such as packages and packaging materials, includes a heated ink supply means which engages with type elements as the latter move from a rest position, in which the type is heated, to a printing position, but which does not engage the type elements as the type elements move from the printing position to the rest position. The type preferably comprises rubber elements, heated in the rest position by a stationary heater. The ink supply preferably comprises an ink roll rotatably and freely mounted in an oven, wherein the ink roll remains in the oven throughout the whole operating cycle. Pneumatic cylinders are provided to move a type holder from the rest position to the printing position and vice versa, as well as for moving the ink supply means into and out of the path of the type holder.

Abstract: A printing apparatus is disclosed wherein rocking motion of a movably mounted inking roll assembly is controlled by a cam and follower arrangement coupled to the drive system for a pivoting printing member. The cam and follower arrangement allows coordinated movement of the printing member and inking roll assembly to be obtained in a simple manner and without employing separate drive means for rocking the inking roll assembly. The cam contour is advantageously chosen so that the inking roll is moved gradually toward and then away from the pivot axis of the printing member as the line of contact between the printing element and the inking roll progresses from the leading edge of the printing element to the trailing edge. Such movement of the inking roll maintains uniform tangential contact between the inking roll and the entire surface of a flat printing element as the latter is moved in an arcuate path by the printing member.

Abstract: A feed mechanism for feeding an elongated strip of labels in a portable labeling machine. The label feed mechanism intermittently advances the label strip with an indexed movement in response to the manual gripping and releasing of a grip lever which acts through an actuating member that is pivotally connected to the grip lever. The label feed mechanism includes a rotatable feed wheel, and it includes a drive member which is connected to the actuating member at a position far from the pivot of the actuating member. The drive member may be a combination of a ratchet lever on the actuating member and a ratchet wheel connected to the feed wheel or it may be a combination of a rack on the actuating member and a pinion on the feed wheel. Between the ratchet wheel or the pinion and the feed wheel is a gear assembly that amplifies motion of the ratchet wheel or pinion. Thus, the manual actions of the grip lever are amplified in the motion of the feed wheel to ensure an elongated advancing motion of the label strip.
