Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . ich rests that portion of thebody which is to form the brim are spread outbetween the vibrating fingers. After 10 or 15stretches are made by the fingers, the block islowered sufficiently to turn the hat upon it, soas to bring the fingers upon that portion whichpreviously rested on the ribs, and the operationis repeated. From 30 to 40 vibrations of thefingers are usually sufficient to stretch the brimto its full extent. These machines differ considerably in construction, according as they are applied to dif-ferent uses. Fig. 2302 represents the Eicke-meyer fur-tip stretcher. In this the fingers aremounted on a spindle which has its bearing inline with the sliding spindle which supports thestar. To this spindle a short walking-beam,which also communicates with the crank-shaft,is hinged. Each revolution of the main shaftthus causes vertical movement of the spindle,and also of the stretching-fingers. In practicethe best results are obtained at from 100 to150 revolutions of the main 104 HAT-MAKING MACHINERY.
