“ The only process that is embodied in the plaintiff's apparatus is the process of bringing the heated products of combustion, impelled by a blast of heated air rushing through the fire built upon the grate, into direct contact with the interior of the cask, and with the pitch which may cover the interior. ”

“ Whether the nozzle terminates in the air or in the interior of a cask or keg, or whether the deoxygenated blast which leaves the nozzle is partially reoxygenated or not before reaching its objective point, does not affect the identity of the apparatus. In reference to both the Cochrane and Slate patent and the 'Pewterer's Blast' apparatus, the patentees have, at most, merely applied an old apparatus to a new use, without any change of its constituent elements or of its mode of operation. ”

“ It also states that in this view the invention has for its object the preparation of casks for receiving the pitch, by subjecting them to blasts of highly-heated air, by means of the apparatus described; that is, the invention is of the apparatus. ”
