Apparatus for use in paper-making machines.

' Application filed February 16,1916. Serial No, 78,603.

To all whom it may concern:

Be it known that I, Charles G. Oberley, a citizen of the United States, residing at Munising, county of Alger, State of Michi5 gan, have made a certain new and useful Invention in Apparatus for Use in PaperMaking Machines, of which the following is a specification.

This invention relates to apparatus for 10 use in paper making machines.

The object of the invention is to provide apparatus which is simple and efficient to prevent paper from adhering to the press or smoothing rolls of paper making mart chines.

Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and 20 relative arrangement of parts, all as will be more fully hereinafter set forth, as. shown by the accompanying drawing, and finally pointed out in the appended claims.

Referring to the drawing:—

Figure 1 is a view in front elevation of a pair of press or smoothing rolls of a paper making machine and showing my invention as applied thereto.

Fig. 2 is a view in side elevation of the 30 same.

The same part is designated by the same reference numeral wherever it occurs in both views.

In the usual type of paper making mass chines, the paper passes on a wire , web or felt between press or smoothing rolls in the course of its manufacture. The paper is damp, and in consequence there is a tendency of the same to stick or adhere to the 40 roll, usually the upper one. The disadvantages of this are obvious. There is great waste and the paper is apt to become torn. To overcome these disadvantages and to provide means which are simple, but effi45 cient, to prevent the paper from adhering to the roll which comes in contact therewith, my present invention is directed.

In the drawing I show the usual press or. smoothing rolls in which 1 designates the 50 upper roll which rotates counter-clockwise, and 2 the lower roll which rotates clockwise, and 3, the web or felt which passes between the rolls 1 and 2, all in the usual well known manner. Mounted on the frame 4, of the S6 rolls 1 and 2, and suitably secured thereto, for example, by bolts 5, are brackets 6, on each end of the upper roll 1, to which are adjustably secured by means of a slot 7, therein a U-shaped arm 8, extending across the width of the rolls, and provided with 60 lugs 9, at their ends in which is journaled a shaft 10, as shown.

Loosely mounted on the shaft 10 at its ends are arms 11 which may be rigidly secured to each other by means of the tie rod 65 12, if desired, and which at their ends form bearings for a shaft 13, of a rotary cylinder 14, which cylinder is provided with vanes 15, of. any suitable strong flexible material, such as rubber, sheet metal or the like.. A 70 spring 16 mounted on the shaft 10 operates to normally force the cylinder 14 toward the top roll 1 in the well known manner, the arms 11 being of such length that the cylinder 14, lies normally just above the 75^spath of travel of the felt or wire 3, as shown in Fig. 2..

The position of the arms 11 and the cylinder 14 is adjustably regulated with respect to the roll 1 by means of the set screw 20. 80 Iftvpractice, the set. screw 20 is. set so that the erids of the vanes 15, upon rotation of the cylinder 14, are in slight contact with the roll 1, as shown. Thus it will be seen that as the rolls rotate, and the paper passes 85 between them on the wire 3, if the cylinder 14 is rotated at a high speed counter clockwise, the vanes 15 thereof scrape the roller 1 thereby preventing the damp paper from adhering thereto. The action of the air due 90 to the vanes operating substantially as a fan also greatly aids the device in effectively preventing the paper from adhering to the roll.

The cylinder , containing the vanes 15,95 may be rotated in any desirable manner. I show one simple arrangement wherein I provide an electric motor 25, to rotate .th© shaft 13, which motor may be secured to the arm 11, at 26, by any suitable means, for 100 example, by the bracket and bolts 27, 28, 29. It is obvious, however, that the shaft 13, may be rotated in many other ways and consequently I do not desire to be limited or restricted,in this respect. I also do not 105 desire to be limited or restricted to the specific arrangement shown, as many changes in detail will readily occur to those skilled in the art without departing from the broad : scope of my invention as defined in th© W
