This is a interesting example of a 19th c. pill making machine. Similar examples first appeared in the mid -1700s and quickly became a staple of the Victorian chemist's shop. A pill mass of medicinal powders mixed with a binding agent would be hand-rolled into a pipe on the tile at the back of the machine. Then it would be placed across the grooved brass plate and cut into equal-sized pills using the corresponding side of the roller. Size 36 x 15cm.
