Abstract
A dispenser for thin flat rigid articles such as glass cover slips for microscope slides comprises a magazine for a stack of such articles and a dispensing block carrying the magazine and reciprocable relative to a spring blade running in a groove in the top of the block and under the magazine. The depth of the grooves changes so that the front of the blade rises as it travels in the groove, under the magazine, from a projection less than the thickness of article to a projection greater than that thickness, so as to engage and push only the lowermost article under a resilient barrier that restrains other articles in the stack. Also disclosed is an automatic microscope slide coverslipping machine incorporating the dispenser.
