Feeding Fingers

Appletons’ Modern Mechanism Supplement of 1895 contains an excellent bookbinding machinery section. The article mentions that machines haven’t changed significantly in the past decade, but performance and efficiency are improved. Chamber’s rotary board cutter is a particular beauty.  I find these hybrid cast iron and wood machines quite interesting since we usually think of machinery as consisting one of the other, not both. Note the automatic board advancement pins on the bed of the machine, which are called “feeding fingers”. OUCH!
