Opinions

Geaham, Presiding Judge,

delivered the opinion of the court:

This appeal is from a decision of the Board of Appeals of the United States Patent Office affirming the decision of the examiner in rejecting claims 12, 13, 15, 21 and 25 to 27, inclusive, of appellants’ application for patent, filed March 16, 1934, serial No. 716,008.

Appellants’ application is for reissue of a patent, 1,882,694, issued October 18, 1932, to appellants, as assignors to The Timken Silent Automatic Company, of Detroit, Michigan, for an improvement in oil burners. As shown by the application, the subject matter of the claimed invention is a device constituting a burner head and mounting therefor. The examiner thus describes the device and its action :

The invention relates to an oil burner (best shown in Pig. 2) of that type in which a x'Otary head is disposed centrally of a hearth and sprays oil to the outer periphery of the hearth, where combustion takes places. * * *
The rotary head is supported by the shaft 18 and comprises the channel member 29, into which oil is delivered by the stationary pipe 26-27, and the oil distributing head 14, through which project the distributor pipes 34 through which the oil is discharged by centrifugal force. Supported on the head is a fan 20, having the disk portion 22 and a peripheral down-turned flange with blades, certain of which are omitted opposite the discharge ends of pipes 34.
The pipes 34 are said to discharge oil through the fan in such a way that the fan blades do not strike the oil streams.

Claim 12 is typical, further ex|Dlains the nature of the device, and is as follows:

12. An oil burner comprising an annular wall, a fan having a disk-like body provided with an annular skirt depending from its periphery, said skirt having a multiplicity of blades projecting outwardly therefrom, said fan being supported for rotation above and in closely spaced relation to said annular wall, a distributor head having radially extending pipes disposed within said fan and terminating relatively close to said skirt, and openings in said skirt opposite said pipes, said openings being spaced from said blades so that oil may'be discharged without interference from said blades.

[933]*933On November 6, 19.34, the appellants copied claims 7 and 8 of a patent to Meilde, No. 1,977,521, issued October 16, 1934, for purposes of interference. On November 14,1934, the examiner finally allowed certain of appellants’ claims, and rejected others, including those here in controversy. These latter claims were rejected on two grounds, first, that they were for new' matter, not included in the original patent; second, on the reference:

Meikle, 1,977,521, Oct. 16, 1984 (issued on application Serial No. 706,456, filed Jan. 13, 1934, as a division of an application Serial No. 291,032, by G. Meikle, filed July 7,1928, entitled “Method of an Apparatus for Producing Combustion”).

On appeal, the Board of Appeals differed with the examiner and reversed him as to his first said ground of rejection and affirmed his decision as to the rejection on Meilde. From that decision, the appellants have appealed.

Both tribunals in the Patent Office held that the Meikle patent, No. 1,977,521, should be given the date of the parent application, namely, July 7, 1928. If given this date, it would antedate appellants’ original patent, dated October 18, 1932. On the other hand, appellants claim that the Meikle patent No. 1,997,521, was based on a disclosure of new subject matter, not found in the parent application, that it was not a true division of the original subject matter, and that, therefore, the Meikle divisional patent was not entitled to the date of the original application, but must be restricted to the date of filing of its own application. The determination of the controversy depends upon this point.

In the parent application of Meikle, filed July 7, 1928, the applicant disclosed a burner head by means of which liquid hydrocarbon fuel was conducted into a revolving breaker member, and from which it was thrown out by centrifugal force in a separated and atomized form to be burned, together with air, upon a baffle structure on the periphery of a hearth. The breaker member consisted of a revolving cup with tubes, and a top, cap-shaped member with a flange covering the saíne, the flange being cut away at places, and being provided with baffles at such points. The liquid hydrocarbon fuel was drawn or forced into the burner head for atomization through tubing 78. As shown by the original drawings accompanying this application of Meikle, these pipes were shown to terminate close to the periphery of the flange, so that fuel might be ejected, free from the interference of the baffles or blades of the breakers.

In the specification of this application, the nature and function of the breakers and their baffles were thus explained:

In order to insure proper atomization of the liquid hydrocarbon fuel and the proper admixture of air for combustion purposes, the nozzle or cup member 16 is provided with a top member 30 that is secured to' the shaft 22 so as to rotate therewith, the top member having an outwardly — and downwardly— [934]*934extending flange 31 which intercepts the combustible mixture emitted from the edge of the nozzle or cup 16 when rotating. For this purpose the flange has segments thereof cut away and is provided with baffles 32. The top members-thus constructed are termed “breakers”, since they operate to effect a more complete atomization of the hydrocarbon fuels and entrainment of air in the process of combustion. * * *
Any convenient arrangement may be employed for this purpose, for example, the disposition shown in Fig. 3 where it is seen that the blades 32 have a direction somewhat inclined to a radius- drawn through its middle point, the inclination of the blades here being such that they respectively lie substantially along the paths of the trajectories of fuel particles when' they leave the lip or edge of the nozzle at the point opposite which the respective baffles, are disposed. * * *
The breakers thus .constructed, perform a three-fold function, namely, first, that of cooperating with the burner nozzle to effect substantially complete atomization of the hydrocarbon fuel projected from the burner nozzle; second, that of redistributing the combustible mixture projected from the burner nozzle in a plurality of horizontal and vertical radial planes instead of in a single sheet; and third, that of entraining air and other gases which are admixed with the combustible mixture projected from the burner. * * *
Here more air may be added to the mixture, the resultant mixture passing out over the nozzle lip at points adjacent the pick-tubes 17 toward the openings in flange 31. In passing through these openings, the fuel particles come in contact with baffle blading 32 where they are further atomized in a plurality of vertical and horizontal planes, * * *.
As this hydrocarbon stream, issuing from the tubing 78, passes through the outer breakers, it is seen to become atomized to provide the combustible mixture desired.

In consideration of this application, the examiner called the applicant’s attention to the fact that his drawings and specification conflicted, stating:
