ABSTRACT:
A semi-automatic teeing device includes a cylindrical housing having a gas inlet port connectable to a gas pressure source; a removable cover for sealed engagement with the housing so as to define therewith a sealable container; a tee mounted within a central support portion of the cover; air-pressure-operated apparatus located within the container for moving the tee between an at-rest position, and a primed position in which the tee supports a practice golf ball at a useful height; and an air-pressure control, responsive to the presence of a practice golf ball on the tee, to substantially seal the container so as to activate the air-pressure-operated apparatus to move the tee from the at-rest position to the primed position and operative, upon removal of the ball from the tee, to release the air pressure within the container, thereby to permit the return of the tee to the at rest position.
