A glue gun having an advancing mechanism which has a longitudinally slidable carriage member with a longitudinal opening for the glue stick is provided. The carriage member has a first transverse opening in communication with the longitudinal opening and a second transverse opening in communication with the first transverse opening which is also transvers to the first transverse opening. The first transverse opening has internal peripheral bearing surfaces. A substantially T-shaped angularly displaceable gripper member is included which has an upper member defining a gripper head and a lower member defining a transverse lever. The gripper head is receivable into the first transverse opening and has a front end, a rear end, an upper end and a gripper tooth near its front and upper ends for gripping the glue stick. The gripper head further has exterior peripheral bearing surfaces near its front and rear ends which slidably bear against the internal peripheral bearing surfaces of the first transverse opening to retain the gripper head in the first transverse opening while permitting angular displacement of the head.

A device for heating a substantially solid heat softenable glue stick until said glue is substantially melted and ejecting said melted glue from said device, said device comprising: (a) a housing; (b) a heating chamber mounted in said housing, said heating chamber having an opening therethrough, an end of said opening defining an entrance for said substantially solid glue stick and another end defining an exit for said melted glue; (c) means for advancing said substantially solid glue stick into the entrance of said opening in said heating chamber to melt said glue and to eject said melted glue from said device, said means comprising a longitudinally slidable carriage member having a longitudinal opening for said glue stick and a transverse opening in communication with said longitudinal opening, said transverse opening having internal peripheral bearing surfaces, an angularly displaceable gripper member having a transverse lever and an gripper head, said transverse lever having an end extending through said transverse opening, said gripper head being receivable into said transverse opening and having a front end, a rear end, an upper end and a gripper tooth near said gripper head front and upper end for gripping said glue stick, said gripper head further having exterior peripheral surfaces substantially defined by its front and rear ends which slidably bear against said internal peripheral bearing surfaces of said transverse opening to retain said gripper head in said transverse opening while permitting angular displacement of said head so that a force applied to said end of said transverse lever will cause angular displacement of said gripper head causing said gripper tooth to grip said glue stick.
