Abstract

A hand operated label printing machine in which a series of labels are incrementally fed onto a printing platen in response to the squeezing of a hand lever so that they may be imprinted with selected indicia. The hand labeler is equipped with an ink supply device, comprising a holder that holds two inking rollers. The holder is movable to bring the inking rollers into and out of contact with the types of the printing device to ink them. The ink supply device is actuated by a mechanism which is comprised of a combination of a cam pivotally attached to the machine frame and a roller pivotable with the printing head supporting printing lever for being received in the cam and for pivoting the cam with the printing lever. A link joins the cam with the holder, so that pivoting of the cam moves the holder. Guide grooves in the machine frame regulate the inking roller motion along different loci. The link has a slot in it which prevents the holder from linear protrusion to the front of the labeler frame.

Dependent claims

A label printing machine, comprising:

a machine frame;
an operating lever pivotally connected to said machine frame and movable from a rest position toward an operative position;
a printing lever connected with said operating lever for moving between a respective rest position when said operating lever is in said rest position and a printing position as said operating lever moves to said operative position;
a printing device, including inkable imprinting types carried on said printing lever;
a platen connected to said machine frame and in opposition to said types as said printing device moves to said printing position, whereby said types will engage a label on said platen when said printing lever is in said printing position;
an ink supply device for inking said types, comprising:
an inking roller holder for holding two separated inking rollers;
turning means connected with said inking roller holder for moving said inking rollers over said types;
a starting cam which is pivotally connected to said machine frame at a different pivot than said operating lever, said starting cam also being pivotally connected to said turning means such that movement of said starting cam, in turn, moves said turning means;
a starting element on said printing lever and in engagement with said starting cam for causing pivoting of said starting cam and said starting cam being shaped to permit relative shifting of said starting element with respect to said starting cam as a result of their pivoting about different respective pivots;
guide means supported in said frame for guiding said inking rollers along different respective paths and over respective said types as said inking rollers are moved by said turning means and said inking roller holder;
said guide means includes a guide groove in said machine frame for guiding one of said inking rollers to regulate the path travelled by said one inking roller and for said one inking roller to move past first respective said types;
said guide means further comprising an elastic member for supporting the other of said inking rollers into abutment contact with a second respective said type of said printing device as said turning means moves said other inking roller over said second type.
