Abstract
A portable device for pulverizing pills, tablets and the like to form a minute substantially uniform powder therefrom. The device includes a cam-driven spring biased ram which reciprocates once on a vertical axis into and out of engagement with a pill disposed therebeneath with sufficient localized force to pulverize the pill. A microswitch interrupts power to the device until it senses that the pill is correctly disposed axially beneath the ram.
