115 F. 324 | U.S. Circuit Court for the District of Western New York | 1902
This is a suit in equity for infringement of United States letters patent No. 586,088, issued to Walter B. Jones July 6, 1897, and assigned by him to complainant. The patent relates to what are described as new and useful improvements in an apparatus for artificial incubating and brooding. Defendants admit that the exhibits in evidence (an incubator and brooder apparatus claimed by complainant to infringe the patent in suit) were made by them, and that they are engaged, as partners, in their manufacture and sale. The claims of the patent alleged to be infringed are 1, 2, 3, 9, and 14. They consist of a combination of elements involving a method of circulating heat or warm air from a source of heat in an incubating and brooding chamber to a heating device attached to the incubating and brooding apparatus, and communicating with the upper part of the chamber. More specifically, a fresh-air inlet pipe is so constructed as to communicate with the upper part of the chamber, whereby the fresh air is warmed before entering the chamber. The inlet pipe is so arranged and connected to the chamber, with an exit pipe leading to the lamp used as a heating device, as to result in controlling the entrance of fresh air into the chamber. As the fresh air is admitted through the inlet pipe, it occupies the space of the vitiated air drawn off by draft or suction caused by the heater. Complainant’s expert says:
“The chamber or heater produces a ratification of the air adjacent thereto, and the colder or heavier air rushes toward it from below, or latterly toward it; and the means for heating is the element that produces the positive circulation of air from the bottom part of the chamber.”
“An incubator or brooder comprising a closed chamber having a fresh-air inlet, means for heating the chamber, including a heating device and an exit pipe connecting said chamber with the heating device, whereby, owing to the draft caused by such heating device, a positive circulation of air within the incubator or brooder is produced, substantially in the manner described.”
The second claim includes means for heating the fresh air before entering the chamber. Claim 3 describes a combination of elements whereby air is heated before it enters the chamber, and for withdrawing the same by suction after it becomes contaminated. Claim 9 describes the means employed to create the suction from the chamber to the lamp or heating device. Claim 14 regulates the quantity of air passing from the chamber to the heating device. The answer alleges aggregation of old devices, anticipation, and denies infringement. Defendants contend that all of the elements upon which are based the claims of the patent in suit are a mere aggregation of known elements; that by the assemblage of parts the patentee has merely aggregaled various elements in his incubator and brooder, without causing them to perform by their united action any new function which they did not perform separately before. His union of forces is not productive of a patentable result. On the argument it was admitted by complainant that practically the only novelty of his claims is an exit pipe arranged to lead from the egg chamber to the heating device. He claims this exit pipe as the essential element of a combination, and that this feature, in conjunction with the other elements described in his claims, produces a vigorous, wholesome, and constant passage of air through the incubator and brooder chamber at a predetermined degree of heat, thus assuring a regular and effective operation of the apparatus at all seasons of the year. At the time complainant’s application for patent was filed, the examiner of patents rejected his specific claims for a ventilating system. The Gouge and Hoadley patents for ventilating apartments and cellars were cited by the patent office in support of the contention that the claims for a system of ventilation resulting in a constant change of air were old and well known. The patentee insisted that the citations were erroneously urged against an invention in incubators and brooders; that to ventilate a house was not analogous to ventilating an incuba
A decree must therefore be entered dismissing the bill, with costs.
