    Abstract: A drill includes a housing and a motor coupled to an output member by a transmission. The transmission can selectively couple the output member to an output spindle through a low speed output gear or a high speed output gear for rotating the output spindle at a first speed or a second speed, respectively. Alternatively or additionally, a low speed mode can be provided by actuating an electronic switch that limits the speed of the motor. A rotatably fixed hammer member and a rotatable hammer member can be mounted around the output spindle. A mode collar can be rotatably mounted on the housing and around the output member for movement to positions that correspond to various mode of operation, including a low speed mode, a high speed mode, and a hammer-drilling mode. In the hammer-drilling mode, the transmission operates in the high speed mode.

    Abstract: An apparatus for the precise dispensing of particulate matter either at a uniform flow rate or in repetitious accurately measured discrete batches. The apparatus includes a housing having a hopper with a hopper outlet orientated over an endless conveyor belt. A metering tube is connected to the hopper outlet and is movable toward and away from the upper surface of the forward run of the conveyor belt. The distance of the lower end of the metering tube from the conveyor belt provides one measure of regulation of flow rate of the particulate matter from the hopper to the conveyor belt. The speed of the conveyor belt provides a second measure of regulation of the rate of flow from the hopper to the conveyor belt and eventually to a dispensing station.
