Opinion

SMITH, Judge.

Appellants appeal from the decision of the board sustaining certain of the examiner’s rejections of appealed claims 70 through 75. The appealed claims originated in U. S. Patent No. 2,864,229 to Seem et al. 1 and were copied into appellants’ parent application here on appeal. 2 After nearly fourteen years of prosecution in the Patent Office, the parent application comes before us on appeal with appellants urging that the board erred in affirming the examiner’s two grounds of rejection of the appealed claims.

The determinative issue here is whether the appealed claims are supported by the disclosure. Since we find that the board properly sustained the examiner’s rejection that the appealed claims are not readable on appellants’ disclosure, it is not necessary to review the board’s affirmance of the rejection based on “double patenting” involving appellants’ patent 3 No. 2,919,534.

Appellants’ invention is directed to a method and apparatus for crimping thermoplastic- yarns. Appellants state in their specification:

In its broadest form, this invention comprises moving a strand of thermoplastic yarn issuing from any conventional source through a heating zone in order to elevate the temperature of at least the outer mieel- *553 lar layer of the yarn to within the plastic range, immediately thereafter passing it over a sharpened edge, preferably in an acutely angular path, and finally collecting the crimped yarn upon a bobbin or the like.

An embodiment of the invention is shown in Fig. 1 of the application on appeal and is here reproduced.

In the specification, appellants explain the operation of this apparatus as follows:

* * * Numeral 13 denotes a conventional yarn supply package, such as a pirn, bobbin, cake or the like. The yarn Y is unwound from this package and passed through a tension device 17, such as a spring-biased disc array. From the tension device, the yarn Y travels upwardly past one side of a blade element 19, over and around the sharpened edge 21 of the blade 19, making an acute bend as it does so, and thence downwardly through a guide 23 to a suitable take-up means, generally designated 25, such as a flanged bobbin 27 driven by a rotating cork-covered roll 29.
The blade 19 is wrapped with several turns of electrical resistance wire 35 to which current is supplied through conductors 33 from a variable transformer 31 connected to any desired source of current, not shown, by leads 34. Sheets of dielectric material, e. g., mica, are provided between the blade and resistance wire, as at 37.
Heat is supplied to the yarn by convection and radiation as it moves past the side of the blade and by conduction as it moves over the edge of the blade so that it is in a suitably plastic condition and capable of responding satisfactorily to the action of the blade in the interval during which it passes over the edge thereof.

The appealed claims consist of independent claims 70 and 75 and dependent claims 71-74. All of the appealed claims contain certain language which the board found was not supported by the disclosure. We think the appealed claims stand or fall together and the parties do not argue otherwise.

Appealed claim 70 is representative:

70. Apparatus for processing yarns comprising a creel for mounting at least one supply package of said yarn, a twister spindle, a traveler ring, a traveler, and feed means to ravel yarn from said supply package and feed the same at a preselected speed to the traveler and take-up package, spaced guide means intermediate said creel and said twister spindle to direct the yarn in *554 a generally straight-line path during at least a portion of its travel, and heater means intermediate said spaced guide means operable to uniformly heat the yarn to a selected temperature during said portion of its travel. [Emphasis added.]

The italicized portion of claim 70 represents that language found by the board not to be supported by the disclosure.

Having the btenefit of the disclosure quoted above from the specification, we may proceed to determine whether claim 70 is supported by that disclosure. 4 Referring to claim 70, “spaced guide means” are “intermediate said creel and said twister.” The specification is silent as to this terminology. This could be interpreted as meaning elements 17 and 23 are “spaced guide means” in Fig. 1, as element 23 is termed a “guide” in the specification and element 17 is a “tension device” which in fact serves as a guide. However, claim 70 further provides that these guide means “direct the yam on a generally straight-line path during at least a portion of its travel,” and that “heater means,” intermediate said spaced guide means, “heat the yarn” during the “generally straight-line path” portion of the yarn’s travel.

It is not readily understandable in what manner elements 23 and 17 can be said to “direct the yarn on a generally straight-line path” and also have heating of the yarn during this generally straight portion of travel. Appellants in one argument 5 explain that element 21, termed a “blade” in the specification, is a “guide,” and that “blade” 21 and “tension device” 17 serve to direct the yarn in a generally straight-line path.

Accepting appellants’ interpretation, claim 70 requires that “heater means” be positioned “intermediate said spaced guide means.” Appellants explain that “blade” 21 is also the “heater means.” Appellants maintain that “blade” 21 is one of a pair of “spaced guide means” and also the “heater means.”

Appellants argue that the foregoing analysis clearly proves that the appealed claims are in fact supported by their specification and that as the terms of the claims are clear and unambiguous, the board committed clear error in resorting to the Seem patent, the origin of the appealed claims, as an aid in determining the meaning of the above terms.

The board, experiencing difficulty in understanding in what manner the appealed claims were supported by the disclosure, did turn to the Seem disclosure for assistance. The board found that its confusion disappeared as the Seem specification disclosed and the claims defined an entirely different invention. The board stated in its opinion:

* * * [Seem] involves no crimping. It is concerned with apparatus for thermally processing a traveling thermoplastic yarn while subjecting it to controlled degrees of tensile stress so as to impart uniform tensile characteristics to the yarn, and employs conventional guides * * * on opposite sides of a heater * * *.
In summary, we agree with the Examiner that the two eases involve distinctly different concepts and structures and that claims 70 to 75 find no reasonable basis in the in *555 stant application.
