. Annual report of the Agricultural Experiment Station. Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). Evaporated Raspberries. 533 which determined the course of the evaporating industry. The Wilharas evaporator, invented by John Williams, South Haven, Michigan, was patented in ISYS. This was soon followed by the Culver machine, which was patented after the death of its inventor (Stephen Culver, ^Newark, N. Y.,) in 1882, by his administrator, Harlan P. Van Dusen, also of Newark.

Culver evaporator," as his son writes me. John W. Cassidy patented his device for lifting trays in 1876. Cassidy was a resident of Kewark, New York, but moved to Petaluma, California, where he resided when he took out his patents. His device, combined with Culver's, is the leading lifting arrangement now in use in western New York. Cassidy took out another patent in 1880 for a device to dry fruit by exposing it alternately to a vacuum or partial vacuum, and an inrush of dehydrated air, but this system is probably unknown in this State. It now needed only the advent of a bleaching device and improved machines for paring and ringing the fruit, to establish the evaporating business upon an enduring basis; but as these devices are not used in the making of evaporated raspberries, they need not be further discussed in this Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cornell University.
