Opinion

HATFIELD, Associate Judge.

This is an appeal in an interference proceeding from the decision of the Board of Appeals of the United States Patent Office affirming the decision of the examiner of interferences awarding priority of invention to appellee.

The counts in issue were taken from appellant’s patent No. 1,649,396, issued November 15, 1927. They read:

“2. In a self-clearing end dump mine ear, wheel axles, a longitudinally extending wood flooring comprising the lowermost longitudinally extending horizontal member of the ear, supporting sills for said flooring, and self-clearing housing over said axles and resting on the wood flooring.
“3. In a self-clearing end dump mine car, wheel axles, a longitudinally extending wood flooring comprising the lowermost longitudinally extending horizontal member of the car, sills for supporting said flooring, axle housings mounted on said flooring and connected to said sills, and ties between the sills and located below the flooring.”
“5. In a self-clearing end dump mine car, wheel axles, side sills carried on said axles, a longitudinally extending wood flooring positioned below the wheél axles and comprising the lowermost longitudinally extending horizontal member of the ear, said sills carrying said flooring, and ties between said sills.”

As stated in the counts, the invention relates to improvements in mine cars.

Counsel for appellant moved to dissolve the interference on the ground that appellee had no right to make the claims constituting the counts in issue. The motion was denied by the law examiner. Thereafter, a petition for rehearing was filed and denied.

In his original decision, the law examiner said:

“In count 2 the lowermost longitudinally extending horizontal member of the oar must be a composite member including such floor planks as are shown at 23, 24 in Field’s Figs. 3, 5, and 6. It is therefore immaterial whether the separate planks extend longitudinally of the ear or across the ear if the flooring as a whole extends longitudinally of the car. This is true of Stew’s floor which comprises transverse wooden elements. Self-clearing housings are shown in Stow’s Fig. 20.
“As to count 3, Stow discloses ties between the sills and located below the flooring in the diagonal members 221, Fig. 3. It is not necessary that these elements should have *841 a floor supporting function to satisfy the count.
“Counts 4 and 5 include no additional elements and demand no further discussion. * * * There are no terms of doubtful meaning in the counts and it is not apparent that any terms require definition outside of their fair and ordinary meaning.”

In denying the petition for rehearing, the law examiner said:

“ * * * The lowermost longitudinally extending member of the ear includes a plurality of floor planks and is a composite member. If the composite member extends longitudinally it is not necessary to satisfy the count that the separate planks should also extend longitudinally to make a longitudinally extending flooring.
“The alleged disclaimer in Stow’s specification, page 6, lines 28 to 31, of a ear construction which includes longitudinally extending wood flooring is merely a statement that the separate planks of the floor are arranged transversely. It is not a disclaimer of a longitudinally extending flooring.”

Due to the fact that the date alleged in appellant’s preliminary statement for conception of the invention defined in the involved counts was subsequent to the filing date of appellee, and it having been held by the law examiner that appellee could make the claims constituting the counts in issue, the examiner of interferences awarded priority of invention to appellee.

The Board of Appeals held that the language “a longitudinally extending wood flooring comprising the lowermost longitudinally extending horizontal member of the ear,” contained in each of the involved counts, was ambiguous and might mean that the planks of the flooring were longitudinally extending, as disclosed in the specification in the patent to Field, or that the “flooring comprising the lowermost longitudinally extending horizontal member” might be considered as a unit without regard to whether the planks extended longitudinally, as disclosed in the patent to Field, or transversely, as disclosed in the application of Stow. The board then said:

“The gist of the invention in this count is a ear, comprising a horizontal floor member extending as a unit, or whole, from one. end of the car to the other longitudinally thereof, said longitudinally extending member comprising the lower most horizontally extending member of the car. supporting sills for said flooring,, and self-clearing housings over said axles and resting on the wood flooring. Such housings are necessary in a car in which the flooring is the lower most horizontal member of the ear and is supported by the sills below the axles in order that the coal in the car may slide over the axles when one end of the car is raised that the load may slide over the inclined floor to be delivered longitudinally of the ear and out from the unraised end of the ear as described by both Field and Stow. Considering the flooring of the car as a unit it is immaterial whether the planks thereof extend longitudinally of the ear or transversely. If Field, the patentee, had intended to limit his flooring to longitudinally extending planks it could have been so specified in the claim by including the wood planks. His invention, however, consisted in a floor extending horizontally and longitudinally of the car and below the axles of the car and apparently he did not wish to limit his claim to longitudinally extending planks. It was immaterial to the invention whether the planks extended in one direction or another transverse thereto. Count 2 does not specify longitudinally extending planks and the count clearly reads upon the construction shown and described by Stow and clearly states the gist of Stow’s invention as well as that of Field. The decision of the Law Examiner is affirmed as to count 2.
“Count 3 differs from count 2 in that it includes 'ties between the sills and located below the flooring.’ Inasmuch as these ties are present in Stow as shown by the ties 221, we think Stow can make this count and the decision of the Law Examiner with regard thereto is affirmed. * * *
“Count 5 specifies ‘a longitudinally extending wood flooring positioned below the axle wheels,’ and since there appears to be nothing material to the invention in construing this expression to mean that the planks of the flooring extend longitudinally, we think the party Stow is entitled to make the claim of count 5 and the decision of the Law Examiner is accordingly affirmed.”

Having reached the conclusion that appellee could make the claims constituting the counts in issue, and as appellant did not claim that he was entitled to priority of invention if appellee was entitled to make the counts in issue, the Board of Appeals awarded priority of invention to appellee. :

Counsel for appellant contends that appellee is not entitled to make the involved counts.
