Opinion

Garrett, Presiding Judge,

delivered the opinion of the court;

This is an appeal'from the decision of the Board of Appeals of the United States Patent Office affirming that of the Primary Examiner rejecting four claims, numbered 6, 7, 9, and 11 of appellant’s application for a patent for alleged “Improvements in Fairleads for Winches.” No claims were allowed.

We quote the claims as follows:

6. In a fairlead for a two-drum winch, the combination of: a base; a T-shaped mast, comprising an erect portion and cross-piece at the top of the erect portion; two fixed sheaves, each journaled on one end of the cross-piece; a bar secured across one face of the erect portion of the mast, parallel to the cross-piece of the mast; two swivel sheaves; two housings, one being for each swivel sheave, each housing having a swivel-axle; two sockets carried by the base, one being for each axle; two sockets carried by the bar, one being for each axle; and means for removably securing the mast to the base, so as to demountably secure the swivel housings.
7. In a fairlead for a two-drum winch, the combination of: a base; a deck-plate; a T-shaped mast, supported by the deck-plate, and comprising an erect portion and a cross-piece at the top of the erect portion; two sheave-housings, one being rigidly mounted at the extreme end face of each end of the cross-piece; a fin along the cross-piece, rigidly secured thereto and to the two sheave-housings; two sheaves, one being journaled in each sheave-housing; two swivel-housings swiveled on the base and mast; and two sheaves, one being journaled in each swivel-housing.
9. In a fairlead for a two-drum winch, the combination of: a base; a T-shaped mast, supported by the base, and comprising an erect portion and a cross-piece; and two sheaves each journaled on one end of the cross-piece.
11. A fairlead according to Claim 7, further characterized by the fact that the erect portion of the mast is made out of a single piece of sheet metal bent into a C horizontal cross-section.

The following general description is taken from the decision of the board:

This application is concerned with improvements in winches of the type used with tractors. The winch is of the two drum type in which the drums are in [1050]*1050alignment. These drums are supported by a base member bolted to the rear 'end of the tractor frame, and are activated from the power take-off of the tractor. The base frame extends over the drums and to this part is attached a plate carrying an upright mast of T-shape. To the head or cross member of this mast are pivoted two sheaves, one on each end of the head. About midway of the pedestal of the mast is attached a horizontal bar having openings for two sheave housings. These housings have pintles mounted in the openings in this plate and at the bottom there are smaller bearings for the lower ends of the .pintles. Within these housings are sheaves over which ropes pass to the work not shown.

In rejecting tlie claims the examiner cited the following references:

LeTourneau, 1,912,645, June 6, 1933.
Lawler, 2,301,782, November 10, 1942.
Hutchins, 2,312,552, March 2, 1943.
French, 2,321,905, June 15, 1943.

It is noted that the LeTourneau patent was cited in connection with the rejection of claim 6, and also another claim numbered 5, which was dismissed from the appeal before the board and is not involved here. The board made no reference to.that patent’in its decision but it was not overruled as a reference and appellant has covered it in the reasons of appeal before us.

In the brief for appellant each of the claims is separately analyzed and discussed. Before making such analysis, however, the brief set forth a general statement, the substance of which is that tl\e application is in a crowded art; that the “outstanding feature” of appellant’s fairlead is that the housings of his upper sheaves are rigidly mounted on the ends of the top piece of a T-shaped mast; that additional details (claimed to be important) are the presence of a bracing-fin extending from sheave-housing to sheave-housing along the top piece of the T and the fact that the stem of the T is C-shaped in horizontal cross section, and that “Of some cumulative importance” is the method of demounting the swiveled housings of the two lower sheaves by unbolting certain described bolts. ■ .

It is alleged that “The whole ensemble produces a more sturdy and compact tractor-winch fairlead than has ever been known before.”

Much emphasis is placed upon the allegation that the application is in a crowded art. Appellant concedes that there are many similarities between his fairlead and the fairleads of the references but contends that “the recital of as much as one essential element; patentably distinct from anything in any of the references, should render a claim allowable.”

Near the end of the brief five elements, claimed to constitute novel features in appellant’s winch, are set forth as follows, the italics being those used in the brief:

First; a T-shaped mast. French’s sheave-support approaches T-shape. Hutchin’s sheave support is T-shaped, it is true, but is associated with his sheaves in a manner not at all comparable with Appellant’s device.
[1051]*1051Secondly, the rigid mounting of the housings of the upper - sheaves transversely on the end faces of the cross-piece. None of the references mounts its upper sheaves rigidly on the end.faces of anything.
Thirdly, the ready demountability of the swiveled, housings of the two lower sheaves (not to be confused with the rigid housings of the two upper sheave's mentioned above). Although each of the four references has lower sheaves which are swiveled, none of the references plans to demount its sheaves in the manner claimed by Appellant.
Fourthly, the reinforcing fin 32. Not only does .none of the references have such a fin — none of them has even some other form of reinforcement performing the function of stich a fin.
Fifthly, the C-shaped cross-section of the stem of the mast. None of the references has this structure. Lawler has merely a D-shaped flat slat, which is something quite different.

The brief then adds:

Surely these five features, which singly and in combination make Appellant’s fairlead the light compact sturdy little tractor-accessary that it is, entitle this fairlead to the limited degree of patent protection which Appellant is asking.

The brief criticizes with some severity both the decision of the examiner and that of the board.

It alleges, in substance, that the former’s analyses of appellant’s fairlead and the fairleads of the references are “verbose and complicated”; that he gave most emphasis to features not relied upon by appellant for patentability, and that his rejection was based on a most complicated combining of the references.

Concerning the decision of the board, the brief asserts, inter alia:
