ABSTRACT:
A device for pressure feeding or injecting a liquid chemical such as a fumigant or the like into a wooden pole is described. One form of the invention comprises a plug member having a threaded shank portion and a hexagonal head portion. A longitudinally extending bore extends through the head portion and the shank portion. A one-way check valve is inserted into the outer end of the longitudinally extending bore to provide a means for injecting the liquid chemical into the pole. A bleeder opening is formed in the shank portion which extends outwardly from the longitudinally extending bore to enable air to be discharged therefrom as the liquid chemical is initially injected into the bore. A modified form of the invention is also described.
