2 Claims. (Cl. 34120) This invention relates to the art of paper making, and more particularly to a mechanism for facilitating the re moval of paper from the drier.

The object of the invention is to provide a mechanism for supplying a suitable quantity of fluid such as kerosene to the vicinity of a drier so that the paper can be more easily removed from the drier.

Another object of the invention is to provide a fluid dispensing mechanism which will strengthen the paper being removed so that such paper can be removed without the paper tearing or breaking.

A further object of the invention is to provide a paper moistening apparatus which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a fragmentary elevational view illustrating a portion of a drier and showing the mechanism of the present invention mounted on the frame.

Figure 2 is a vertical sectional view taken through one of the fluid holding containers.

Figure 3 is a fragmentary elevational view illustrating one of the sleeves and the wick projecting therefrom.

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a sectional view taken on the line 5-5 of Figure 3.

Referring in detail to the drawings, the numeral designates a frame which includes spaced apart side members 11 that have trunnions 12 extending inwardly therefrom, and a drier drum 14 may be mounted on the trunnions 12. A bar 16 may extend between the support members 11 and may be secured thereto in any suitable manner, there being doctor blades 17 provided.

Extending outwardly from each of the support members 11 and secured thereto is a bracket 18 which sup ports a container or housing 19. A lid or cover 20 is detachably connected to each of the containers 19, and the containers 19 are adapted to hold a suitable quantity of fluid 21 therein, and the fluid may be kerosene.

Depending from each of the containers 19 is a pipe 22 which may be held in its proper place by means of a nut 23. A hose or conduit 24 may be connected to the pipe 22 by means of a clamp 25, Figure 2. A vertically disposed sleeve or collar 26 is connected to the other end of the conduit 24 by means of clamps 27, and the clamps 27 may be secured to the bar 16 by means of bolt and nut assemblies 28. A Wick 29 extends down through the sleeve 26 and into a portion of the conduit 24, and the wicks 29 are adapted to convey the fluid 21 to the desired location. It is to be noted as shown in Figure 1 that the upper ends of the wicks 29 project above the containers 19 so that there will be no overflowing of fluid.

From the foregoing, it is apparent that there has been provided an apparatus which will facilitate the removal of paper from a drier drum 14. In use, the containers 19 may be filled with a suitable quantity of fluid such as kerosene 21 by first removing the lids 20. Then, the fluid 21 willpass down through the pipes 22 and enter the conduits 24 and this fluid will saturate the wicks 29. The fiuid will be carried up through the wicks 29 by capillary action so that the fluid will volatilize .or be discharged in the vicinity of the doctor knives 17. Thus, the paper will be moistened slightly so that as it is being removed from the drum 14 it will not tear or accidentally break. The kerosene is absorbed by the wick 29 and is carried up onto the drier at the edge thereof where the paper is running so as to strengthen and more easily free the paper from the drier. Thus, the paper drying or making machines can be operated more efficiently and more economically since the machines will not have to be shut down to repair torn or broken strips of paper. Each machine may have two of the mechanisms mounted thereon as shown in Figure 1. A guide ro'll can be provided for the paper as it leaves the roll. The containers 19 and lids 20 may be made of a suitable material such as plastic. Suitable washers can be used wherever de sired to prevent leakage of the fluid. By having the supply containers 19 slightly lower than the tops of the sleeves 26, there will be no overflowing of fluid. The size of the parts can be varied as desired and the parts can be made of any suitable material.

It is to be understood that the drier in the paper making art refers to an iron drum which may vary in size, and as for example may be 12 wide and 10' in diameter, and may weigh from 30 to 35 tons and may carry up to 30 pounds of steam pressure. The paper comes in contact with the drier in a damp condition and leaves the drier in a dry condition. A single sheet runs over the drier at a time, so by applying the kerosene directly on the drier at the edges between where the paper is picked up and leaves, it is absorbed by the paper edges or trim. The whole sheet of paper is then carried through other paper making equipment and wound on a reel and built up to various diameters, and the reel is placed on a winder where the edges are trimmed and the reel cut into various sizes. In the event that the sheet breaks at the drier, the doctor blades 17 shave the sheet off the drier so as to prevent the sheet of paper from wrapping the drier and the doctor blades press continually on the drier and keep it clean. The drier, doctor blades, and guide roll are conventional parts of paper machines. The kerosene is used because it does an eflicient job of freeing the paper at the edges of the hot drier so that good reels are built up without cracked edges. Also, the material will be trimmed correctly on the winder and the kerosene does not harm felts or machines in any way nor does it discolor or give ofi obnoxious odors.

It is to be understood that changes in the apparatus can be made insofar as such changes fall within the scope of the appended claims.

I claim:

1. In combination, a frame including spaced parallel support members, opposed trunnions extending from said support members, a drier drum mounted on said trunnions, a bar extending between said support members, doctor blades arranged contiguous to said drum, a bracket secured to each of said support members, a container supported by each of said brackets and adapted to hold a quantity of fluid, a vertically disposed tube depending from each of said containers, a conduit having one end connected to said tube, a vertically disposed sleeve connected to the other end of said conduit and said sleeve being secured to said bar, a wick projecting through said sleeve and into said conduit, the upper end of said wicks terminating adjacent to said drier drum, a lid detachably connected to the upper end of said container, the top of said sleeves being positioned above the top of said containers.

2. In a device of the character described, a frame embodying spaced parallel support members, opposed trunnions extending from said support members, a drier'dru rn mounted on said trunnions, abar extending between said support members and secured thereto, a a plurality of doctor blades arranged contiguous to said drum, a bracket secured to each of said support members and extending v outwardly therefrom, acontainersupported by each of said brackets and adapted to hold a quantity of fluid, a vertically disposed tube depending from each of said containers, a conduit having one end connected to said tube, a vertically disposed sleeve connected to the other end of said conduit and said sleeve being secured to said bar, a wick projecting through said sleeve and into said conduit, the upper ends of said wicks terminating adjacent to said drier drum, a lid detachably connected to the upper end of said container, the upper ends of said wicks projecting above the top of said containers so that there will be no overflowing of fluid, and whereby the fluid will be carried up through the wicks by capillary action so that the fluid will volatilize or be discharged in the vicinity of the doctor knives so that the paper will be moistened slightly so that as the paper is being removed from the drum it will not tear or accidentally break, and whereby the fluid which is absorbed by the wicks will be carried up onto the drier at the edge thereof where the paper is running so as to strengthen and more easily free the paper from the drier.
