86 F.2d 829 | C.C.P.A. | 1936
delivered the opinion of the court:
The appellant filed an application in the United States Patent Office for a patent on certain improvements in projecting machines. Several claims were allowed, but claims 8, 9, 10, and 15 were rejected by both the examiner and the Board of Appeals, on the following references:
Percy (British), 12,599, May 24, 1910.
Gallo & Galinou (French), 456,917, June 30, 1913.
Claim 8 is typical, and is as follows:
8. A projecting machine head having two adjacent vertically extending light apertures inclined to one another, a lamp for each of said light apertures disposed in said head, light directing means for directing the light rays from each lamp through one of said light apertures in a substantially horizontal direction, each lamp and its associated light directing means being spaced from its light aperture to clear the light rays moving toward the other light aperture, the light rays so moving toward their respective light apertures crossing one another before reaching their respective light apertures, tape guiding means associated with said light apertures, and means for drawing a tape successively across said light apertures.
The invention relates to a stock ticker projecting head. This head is so arranged as to project the printed matter upon the ticker tape in two directions at the same time. The head is arranged with two lights, each with a reflector and pair-of lenses. These lights are arranged at right angles to each other, each lamp being placed in a rectangular recess. The rays are projected in straight lines toward the emitting openings in such a way that the rays of light cross each other at right angles with the head. The ticker tape is moved successively across the lenses in the openings, so that the lamps will project the quotation appearing on the tape upon suitable screens. The focal lengths of the lenses are unequal. The light directing units are so spaced from the light apertures as to clear the light rays moving toward the other apertures.
The British patent to Percy shows a projecting apparatus, especially in Figure 13, with one light and one film, but with four
The French patent to Gallo et al. proposes to utilize the same film for projecting motion pictures “onto a more or less considerable number of screens, which may be disposed either at the same level in various directions or at different levels and likewise in various directions.” In the patent, the film is so arranged that it will respectively pass before several multiple condensing lenses, distinct from each other, onto different screens. The patent shows one source of light, but several, in this case four, different reflectors and condensers for the emission of light in the desired direction. Some of these light projecting means are shown with a succession of mirrors so that the light will be deflected one or more times before it reaches its objective screen.
(1) The appellant argues that the Gallo et al. patent is not operative, as the image which is reflected in some cases will be reflected backwards, and in others upside down and backwards, because of the number of reflections by the mirrors which are used. Therefore, appellant insists that the Gallo' et al. patent ought not to be used as a reference, it being claimed to be inoperative. However, it will be noted that this point was not considered in the decisions of the tribunals below, and we are not in position to consider the same
In addition to what is here said, our discussion of the Gallo reference in In re Eitzen, 24 C. C. P. A. (Patents), 772, 86 F. (2d) 411 (No. 3707), is apropos.
(2) It will furthermore be observed that none of the rejected claims recite any particular method for showing the images upon the screens. The appellant does not argue that the references will not produce a multiple of projections, but that he is producing a “particular type of multiple projection,” as indicated in each claim: to wit, a number of projections which are disposed at right angles to one another so that the light rays, from sources of light, cross one another before reaching their respective light apertures. While the disclosure of appellant shows the particular feature of intersecting rays of light, it is not shown wherein such an arrangement is inventive, and the Patent Office tribunals are of opinion that no such invention is embodied in this idea.
We agree with the Board of Appeals that claims 8, 9, 10, and 15 were properly rejected, and its decision is affirmed.
