granted for the Hickman Grand Piano Action and improvements U.S. Patents 1,823,142 & 1,866,707 compiled by Robbie Rhodes The images in the list following were downloaded from the web site of
the U.S. Patent & Trademark Office (USPTO):
The TIFF images from USPTO are compressed using CCITT Fax Group 4 compression, which is a lossless and powerful method but it is not supported by all image viewers, and so GIF files have also been created. (A browser plug-in which displays TIFF images can be downloaded from http://www.alternatiff.com/).
