Opinion

JOHNSON, Judge.

This is an appeal from the decision of the Board of Appeals of the United States Patent Office affirming the decision of the Primary Examiner ’rejecting claims 14, 15, 16, 17, and 21 in appellant’s application for a patent for an invention relating to a “Compound Brief Case.” Process Claims 18, 19, 20, and 22 were allowed.

The appealed claims read:

“14. In a brief case, a gusset, a panel comprising complementary elbows defining a rim including upper horizontally alined and independent reaches having inner ends disposed in juxtaposition and including downwardly extending limbs depending from outer portions of said reaches, said reaches and limbs including lower and side margins respectively and constituting an opening defining an open span, a swingable closure flap for covering said opening and overlapping said margins and having a lower portion intervening said span and secured to the lower part of said gusset, tapes secured to said margins and to said flap and offset relatively thereto, and means securing said panel to said gusset.

“15. In a brief case, a gusset, a panel comprising complementary elbows defining an inverted substantially U shaped rim including upper horizontally alined and independent reaches having inner ends contiguously disposed and including downwardly extending limbs depending from outer portions of said reaches and limbs including lower and side margins respectively and constituting an opening defining *262 an open span at the lower parts of said limbs, a swigable closure flap for covering said opening and overlapping said margins and having a lower portion intervening said span and secured to the lower part of said gusset, tapes secured to said margins and to said flap and offset relatively thereto, and means securing said panel to said gusset.

“16. In a brief case, a gusset, a panel comprising complementary inverted L shaped elbows defining a rim including upper horizontally alined reaches disconnected from each other having inner ends and including downwardly extending limbs depending from outer portions of said reaches, said reaches and limbs including lower and side margins respectively and constituting an opening defining an open span at the lower ends of said reaches, a swingable closure flap for covering said opening and overlapping said margins and having a lower marginal portion intervening said span and secured to the lower marginal part of said gusset, tapes secured to said margins and to side and upper margins of said flap and offset relatively thereto, and means securing said panel to said gusset.

“17. In a brief case, a gusset, a panel comprising complementary and inverted L shaped elbows defining an inverted U shaped rim including upper horizontally alined and independent reaches having contiguously arranged inner ends disconnected from each other and including downwardly extending limbs depending from outer portions of said reaches, said reaches and limbs including lower and side margins respectively and constituting an opening defining an open span, a swing-able closure flap for covering said opening and overlapping said margins and having a lower portion intervening said span and secured to the lower part of said gusset, tapes secured to said margins and to said flap and offset relatively thereto, means securing said panel to said gusset, and expandible and contractible bellows secured to said flap and panel, and a swing-able tongue having one end covering said inner ends and secured thereto.

“21. As a new article of manufacture comprising, a blank cut to form a pair of inverted substantially L shaped elbows having horizontally alined reaches spaced apart by an insert and having a limb vertically depending from the outer marginal portion of each of said reaches and concomitantly defining a flap spanning said limbs and disposed below and contiguously to said reaches to provide an appreciable separation between said limbs and having a lower marginal portion projecting beyond said limbs, said elbows and flap being completely separated from said blank to be clear of said insert for bringing together the inner ends of said reaches and in alinement and juxtaposition to constitute with said limbs an opening smaller than said separation, said flap being smaller than said opening and mounted on said elbows to arrange said lower marginal portion to intervene and to be in line with the lower margins of said limbs and to cover said opening and to overlap the lower margins of said reaches and the inner margins of said limbs, a reinforcing flap covering and secured to said juxtaposi-tioned inner ends, and disconnectable fastening means secured to the side and upper margins of said flap and to said inner and lower margins of said elbows.”

The references relied upon are: Hagelberg 359,150, Mar. 8, 1887; White 1,367,574, Feb. 8, 1921; Guenther et al. 2,316,328, Apr. 13, 1943; Lifton 2,418,589, Apr. 8, 1947; Hochner, 2,438,780, Mar. 30, 1948.

Appellant’s application relates to a compound brief case, which includes a gusset fastened by stitching to a panel comprising complementary elbows which define a rim. The rim includes upper horizontally alined and independent reaches having inner ends in juxtaposition and downwardly extending limbs depending from the outer portions of the reaches. The reaches and limbs include lower and side margins respectively and constitute an opening defining an open span. A swingable closure flap for covering the opening and overlapping the margins is secured to the lower part of the gusset intervening the span. Tapes are secured to the margins and to *263 the flap and are offset relatively thereto. There is a swingable tongue which covers the juxtapositioned inner ends of the horizontal reaches for reinforcing purposes.

Appellant contends that the appealed claims are directed to an improvement over appellant’s earlier structure in Letters Patent No. 2,418,589, supra, wherein the closure flap is integral with the panel and held in the same plane therewith by conventional slide fasteners. In actual practice the fasteners of the patented structure are not only difficult to apply but after attachment they lay substantially parallel to the flap and the panel in the locked position thereby permitting rain to seep into the brief case through the exposed tapes.

To overcome those problems appellant proposes to use one blank of leather for both the panel and the closure flap by cutting the flap to shape so that L shaped jux-tapositioned elbows are formed at the same time as the flap and from the same piece of stock. The L shaped elbows are then connected to form an opening smaller than the flap, creating a more economically produced brief case wherein the flap overlap prevents seepage and also permits greater ease in attachment of the slide fasteners.

The patent to White, supra, relates to a traveling bag. A recess or compartment is formed in one side of the bag. A cover which is secured along the lower edge of the body of the bag on a line below the bottom of the recess or compartment is used to cover the recess or compartment. The upper end of the cover is cut out to form flaps which extend over the frame and inside the bag. The flaps have eyelets and slots which engage fasteners secured within the bag.

The patent to Guenther et al., supra, relates to a side pocket for brief cases and the like.
