“This was an action on the case for an infringement of a patent granted to Edward Treadwell on the 181h of May 1826, for an improvement in the art of manufacturing biscuit and sugar, bread. The schedule describes the whole instrument, viz. the circular knives, dotters, clearers, the holes and the niches for connecting the cakes and clearing away the loose dough, as in the former patent. But it disclaims the piercers or dotters, as used in the well known dotter used by hand, and declares that the patentee does not claim as his improvement either the circular knives, the dischargers, or clearers, or the use of the knives to cut, the piercers to prick, nor the clearers to discharge the biscuit, these having been long known and occasionally used by many persons. ‘What he claims is, his improvement in this machine for saving labour are, the contrivance specified for attaching and keeping the biscuit in clusters, particularly the small cuts, niches, or places filed away for attaching the biscuits, and the holes for the passage of the dough through the plate, and the circular connexion of the cluster of seven knives in this new combination to save labour.’ On the 23d of May 1826 Edward Treadwell, in consideration of'$700, assigned to Elizabeth Watson the patent right, so far as the same applies to the city and county of Philadelphia, and all other towns and villages bordering on the river Delaware from Easton to Newcastle inclusive.”
