Abstract
336,900. Volet, R. A. L. Feb. 8, 1929, [Convention date]. Drilling-machines.-A stand for a portable drilling &c. machine comprises a pillar b attached to a base c and slidably supporting a bracket h which is normally raised by a spring g. The lower limb h<2> of the bracket is provided with a boss h<3> for receiving the cylindrical end a' of the portable electric or other drill a and the upper limb h<1> receives a slidable pointed plunger i normally pressed by a spring j into contact with a recess in the upper end of the drill. The plunger is connected by a pin i<2> to a slot d‹ in a lever d pivoted at e to an adjustable bracket f on the pillar. The lever d serves for feeding the drill and on being raised past its normal highest point releases the plunger from the drill and allows the latter to be removed readily from the bracket h.
