Patents and Patent Claims.—The number of patents issued weekly having become so great, with a probability of a continual increase, has decided us to publish, in future, other and more interesting matter in place of the Claims. The Claims have occupied from three to four pages a week, and are believed to be of interest to only a comparative few of our readers. The publication of the names of patentees, and title of their inventions will be continued; and, also, as heretofore, a brief description of the most important inventions. We have made such arrangements that we are not only prepared to furnish copies of Claims, but full Specifications at the annexed For copy of Claim of any Patent issued within 80 years.......................$1 A sketch from the model or drawing, relattn$lo such portion of a machine as the Claim covers,from.................................................$1 upward, but usually at the price above named.
