Description: |
| "My invention relates to certain improvements in steam-engines, designed more particularly for the production of power for driving sewing-machines, small lathes, and other light machinery..."This patent was litigated in "Shipman Engine Co. v. (George V.) McLaughlin", and, previous to that, "Shipman Engine Co. v. Rochester Tool Works, 34 Fed. 747". The judge in the earlier case held that Shipman was, in the words of the later judge, "not a pioneer in the art of utilizing liquid fuel as a substitute for coal for producing heat or steam; that he only assumes to have invented certain improvements in hydrocarbon furnaces for use under a steam boiler; that his apparatus consisted of a 'combination of parts, each of which was old and well-known when he took up the subject, several of which had previously been used in such burners to perform in combination the functions they performed in his apparatus, but all of which had never before been combined together in the same apparatus.' He further held that the invention of Shipman resided in his valve or regulator in the steam pipe, by means of which the flow of oil is controlled by the steam suction which is automatically regulated by the valve; that this regulator performed a new function, in that it dispensed with an additional valve in the oil pipe which existed in prior furnaces." |
