What is Simplified Cross Section Slicer about?

Simplified Cross Section Slicer.-DR. J. I. HARDY, senior fiber technologist of the Bureau of Animal Industry, has invented a small mechanical device which makes possible the rapid cross sectioning and clear study of the structure of hair, wool, mohair, fur, silk, cotton and other fibers, both natural and artificial. The new discovery enables the preparation of very thin cross sections ready for examination within ten minutes, whereas in the past it required several hours to obtain them. Sections, one-ten thousandth of an inch, can be cut without injury to the delicate internal structure. Moreover, such thin cross sections, even of seemingly opaque fibers, are sufficiently transparent for microscopic study. Dr. Hardy has applied for a public patent on his device, which is about 3 inches in length and consists of three metal parts. A thin piece of metal contains a slot 0.0085 of an inch wide. A second thin flat piece of metal slides parallel to the first and pushes a short metal guide down the slot, pressing the fibers tightly together in a vertical position. The third part contains a small metal plunger on the end of a supporting screw for pushing the fibers ever so slightly through
