ATTORNEYS LESTER ERNEST MILKEY, OF SAN'DUSKY, OHIO.
PAPER-MAKING MACHINE.
Specification of Letters Patent.
Patented Aug. 9, 1921.
Application filed August 6, 1920. Serial No. 401,725.
To all whom it may! concern Be it known that I, LESTER E. MILKEY, a citizen of the United States, and a resident of Sandusky, in the county of Erie and State of Ohio, have invented a new and Improved Paper-Making Machine, of which the following .is a full, clear, and exact descrip-- tion.
This invention relates to improvements in paper making machines, an object of the invention being to provide improved means for removing the moisture from the paper,
fabric, or other similar material while the latter is moving in the form of a sheet.
A further object is to provide an improved blow roll against which paper, fabric, etc,
is smoothly held between perforated aprons, strips or conveyers so that air of any desired temperature can be forced through or into contact with the sheet to remove the moisture therefrom.
A further object is to provide a machine of the character stated in which air under confined between a pair of perforated belts .or endless carrlers.
With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.
In the accompanying drawings- I Figure 1 is a view in longitudinal section illustrating my improved paper making ma chine.
Fig. 2 is a view in transverse section through the blow roll.
Fig. 3 is an enlarged fragmentary view in section of the periphery of the blow roll.
Fig. 4 is a view in longitudinal section illustrating a modification.
Fig. 5 is a fragmentary view in section of a modified form of blow roll.
1 represents a sheet of paper, fabric, or other material as it is formed by any approved method in the manufacture of paperand the like, and '2 are the ordinary suction boxes over which the sheet 1 is fed.
3 represents my improved blow roll which is of general cylindrical form having heads 4; and 5 in its ends fixed or secured to a holl0w hub 6. The head 4 has a tapering or conlcal central portion 7 with a cylindrical extension 8 in which a cylindrical valve 9 is mounted and a coiled spring 10 is located around the valve 9 and between a disk 11 on the outer end of the extension 8 and a shoulder 12 on the valve exerting inward pressure on the Valve to maintain the conical or taper- 1ng inner end 13 of the valve in airtight engagement with the conical or tapering p0rtion 7 of head 4.
The roll 3 is divided by radial partitions 14 into a circular series of radial compartments 15 and each of these compartments has an inlet 16 which is adapted to register with ports 17 in the valve 9 so that certain of the chambers or compartments 15 are in communication with the air inlet valve 9 and receive air therefrom while the other chambers are cut off from the air supply. An air supply pipe 17- communicates with one end of the valve 9 and supplies air under the desired temperature for the purpose intended.
It will be noted particularly by reference to Fig. 2, that only the chambers 15 at the lower portion of the roll are in communica tion with the air inlet and it is these lower chambers which serve to direct the air against the sheet 1 as will more fully hereinafter appear.
The roll 3, or rather the cylindrical wall of said roll, is provided with perforations 18 extending through the wall thereof and the extreme outer periphery or surface of the roll is made with flared outlet mouths 19 communicating with the perforations 18 so that the outer surface of the roll presents as far as possible an extended air discharging surface to direct the air against the sheet 1. 20 represents a perforated belt or apron which is preferably of wire mesh and is passed around three rollers 21, 22 and 23 with the upper run of the'belt 20 located around the under portion of the blow roll 3 24 represents a second endless perforated belt or apron which is also preferablyof wire mesh and this belt or apron 24 is passed around rollers 25 and 26 and is located directly against the periphery of the roll 3;
The sheet 1 passes between the endless belts or aprons 20 and- 24 and is carried thereby around the lower portion of the periphery of the blow roll so that in its passage around the blow roll it is supported between a pair of perforated belts or aprons In Fig. 4 I illustrate a modification in which a stationary air box 27 is located within a hollow perforated roll 28 and is providedwith cut-off partitions 29 and perforated outlets 30 communicating with the chamber or space 31 at the lower portion of the roll so that the air blown from the box 27 is discharged through the lower portion only of the roll. I may also provide a pair of press rolls 28' to press the sheet or fabric against the cut-off partitions 29.
In this modification Ialso carry out the idea of a pair of endless perforated belts or aprons 32 and 33 between which the sheet 1 is carried and supported in its passage around the blow roll 38.
In the-modification illustrated in Fig. 5, I show the blow roll '34, corresponding to the blow roll 3 of the preferred form, as having a perforated cover 35, which may be of wire mesh, around the outside of the roll, andwhen so equipped, the upper apron or conveyer 24 may be dispensed with as the paper will thus be supported between perforated thicknesses in its passage around the periphery of the blow roll.
The operation is, therefore, as follows: The moist paper coming from across the suction boxes 2 passes over roller 21 and thence between the perforated aprons or belts 24 and 20 and is carried by these aprons and belllts around the lower portion of the blow r0 3. I
As above stated, the lower chambers of the revolving blow roll are maintained in open communication with, the supply from the pipe 17 and valve 9, so that the air which is heated or dried in any approved manner is directed through the lower chambers 15 of the blow roll and through the perforations 18 thereof into contact or through the sheet 1 to carry with it the moisture of the sheet. This air may be heated to any desired temperature and is under the desired pressure so that the absorption of the moisture is accomplished by the carrying of the water as such along with the air as the latter rushes may be used as a conveyer for chemicals for disinfecting or liquids for coloring the sheet during the blowing-operation.
With my improved mechanism lumps or thick spots in the sheet are dewatered or dried aswell as the smoother portions of the sheet, and I am enabled to employ any pressure and temperature desired which is not possible with the ordinary suction methods in general use. 1
Furthermore, my improved machine permits a large volume of hot dry air to be continuously forced through the sheet of paper or fabric under a controllable pressure and volume and it is therefore a continuous process.
It will thus be noted that I utilize a means for holding the sheet smoothly and under pressure and in firm contact with the periphery of the blow roll so that the pressure of the air as well as its temperature is utilized to remove the moisture from the paper and the paper is prevented from being damaged by the pressure because it is supported between the perforated belts, aprons or conveyers. In other words the perforated apron 20 exerts a mechanical pressure on the paper and thereby cooperates with the dry air under pressure in removing the moisture from the paper.
Various other slight changes might be made in the general form and arrangement of parts described without'departing from the invention, and hence I do not limit my- I self to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit andscope of the appended claims.
