Opinion

Garrett, Judge,

delivered the opinion of the court:

Appellant’s application for patent was filed in the United States Patent Office November 25, 1932. Three claims stand allowed, but eighteen were rejected by the examiner for want of invention over prior art, six of them (the method claims) being also rejected because held to define merely the function of the apparatus. The Board of Appeals affirmed the decision of the examiner and appellant brings the matter to this court for review.

[1085]*1085The rejected claims are numbered 1, 3, 17 to 28, inclusive, and 31 to 34, inclusive. Claims 1, 3 and 22 to 25, inclusive, are method claims. The others are for the apparatus.

As illustrative of the subject matter we quote claims 1 and 17, as follows:

1. A method of dispensing a sheet material having on one side a normally active externally exposed adhesive coating, which includes as steps thereof causing the active adhesive coated side of the sheet to contact with and thereby adhere to a movable measuring surface, and controlling the amount of sheet dispensed by regulating the movement of said surface.
17. In a sheet dispensing apparatus, in combination, means Ijor supporting a quantity of sheet material said material having an exposed and normally pressure sensitive adhesive coating on one surface thereof, and a roller for measuring the sheet material and to which said material is caused to adhere by the action of said coating while dispensing.

The references cited are:

Anable, 897,510, Sept. 1, 1908.
Drew, 1,760,820, May 27, 1930.
Krueger, 1,914,375, June 20, 1933.

The application discloses a method of and an apparatus for dispensing “in predetermined or measured quantities,” sheet material, particularly tape having one of its surfaces coated with adhesive. The specification mentions the tape disclosed in the cited patent to Drew, which patent states, in substance, that the tape, apparently of paper, is of peculiar utility in masking portions of the surfaces of automobile bodies when paint is applied to such surfaces by spraying. Appellant describes the adhesive as a “pressure sensitive adhesive” and says in his specification that the adhesiveness is “relied upon in a large degree to complete the function of the method and apparatus involved in this invention.”

Before us, counsel for appellant emphasizes that feature of the claims expressed in claim 17, supra, by the clause reading, “a roller for measuring the sheet material and to which said material is caused to adhere by the action of said coating while dispensing.” This feature is present in all the claims and is disclosed in the specification and drawings. The tape to be dispensed is in roll form and is placed upon a drum which serves as a carrier for the roll. As the tape is drawn from the roll it passes over a roller, referred to as a “measuring member,” and then below a substantially horizontal metal member provided with a serrated edge for severing the tape at the point desired. The roller is equipped with apertures located adjacent its ends and spaced at any desired intervals. A pawl is provided for engaging the apertures and controlling the rotation of the roller, the pawl being mounted upon a spring lever. When the spring lever is pressed downwardly the pawl is disengaged from [1086]*1086the roller. When the pressure upon the spring is released the pawl again contacts the roller and when it engages an aperture the operation ceases while the tape is severed. So, the length of the tape to be cut is determined by the distance between the apertures. By keeping the spring lever pressed downwardly, however, the tape may be drawn out to any length desired. It is stated at different places in the specification that the tape adheres to the roller or measuring member, and this adhesion is claimed to rotate the member as the tape is drawn by the hand of the operator. In view of the issue, it is unnecessary to state further details of the operation.

The Drew reference, as has been said, is alluded to in appellant’s specification as disclosing a form of tape for the dispensing of which appellant’s device is designed. The Krueger patent seems to have been cited with reference to certain of the claims which show a particular arrangement of the severing device. It discloses a device in which tape passes over a roller and is severed by means located adjacent the roller and above the tape being dispensed.

The principal reference is the patent to Anable. This patent is for a strip-serving device, seemingly paper strips either gummed or un-gummed. When gummed paper is used means are provided for moistening the gum; when ungummed paper is used an adhesive is substituted for the water in the moistening device. The material from which the strips are to be served, or dispensed, is mounted upon a spindle. When pulled at the end the material unrolls from the roll, passes under a small guide roller and then between two rollers, designated in the drawing by the numerals 5 and 14, and thence under another small roller beyond which it passes over the moistening unit to the means whereby it is severed. Adjacent one end of the roller 5, and mounted on the same shaft is a toothed gear designated in the drawing by the numeral 7. Upon the face of roller 5 is a ratchet gear. A pawl mounted on the toothed gear cooperates with a ratchet gear to cause the roller 5 to rotate in a clockwise direction but permitting the toothed gear to rotate counter-clockwise without imparting movement to the roller 5 which is stated to be loosely mounted upon a horizontal shaft, which shaft is loosely journaled in the framing of the machine. Anable supplies a pair of levers upon one end of which, he states, “is loosely mounted a roll 14 and also a gear 15, preferably of substantially equal diameter, the gear 15 being adapted to mesh with the gear 7 when the strip is drawn upon for use.”

The examiner held Anable’s lower roller, 5, to be the measuring-roller, saying that the contention on the part of appellant that the upper roller, 14, is such “is not in agreement with Anable’s specification,” and broadly held, in effect, as to all the claims, that “there [1087]*1087would be no invention in dispensing the paper of Drew in Anable’s machine.”

The board said:

If a sheet of material such as is shown by Drew be substituted in the Anable patent, it is believed that all of the present claims are met in all substantial respects.

Appellant argues that ambiguity exists in that part of Anable’s specification which reads:

I mount upon the framing a lever or pair of levers 13, upon one end whereof is loosely mounted a roll 14 and also a gear 15. (Italics quoted from brief).

Appellant insists that the italicized phrase is capable of an interpretation to mean that the gear 15 is loosely mounted upon the lever end as well as roller 14, but that, if this be the case, it results (for the reasons given in explaining the operation of the device) that Anable’s disclosure is of an inoperative device. It is then' said, with explanation of the operation of.
