PAPER-MAKING MACHINE.
SPECIFICATION forming part of Letters Patent No. 296,083, dated April 1, 1884.
Application filed January 31, 1884. No model.) Patented in Austria-Hungary August 30, 1881, No. 17,265 and No. 31,172, and
in Germany January 13, 1882. No. 19,193.
To all whom it may concern Be it known that I, J OHN VALENTIN STEN- GER, of Frohnleiten, in the Duchy of Styria and Empire of Austria, have invented a new and useful Improvement in Paper-Making Machines; and the followingis declared to be a description of the same.
This invention refers to that kind of papermaking machines heretofore employed in which a band of wire fabric has passed around cylinders, and a cylinder has been covered at its circumference with both a coarse under wire and a fine top wire, and revolves in avat filledwith pulp and water, and in which machines the sheet of wet pulp is deposited on the fine top wire on the surface of the cylinder.
The object of the present invention is to obviate the difficulties experienced in the aforesaid paper-making machines, and to combine their advantages in one machine, employing both a cylinder covered with wire cloth or fab- I and an endless web of fine wire-cloth passing over said cylinder and over other cylinders at the place of delivery of the sheet of paper-pulp; and I also use in my improved machine cylinders 0r bands of thin rubber passing around the ends of the wire-cloth cylinder and between the circumference of coarse wire and the web of fine wire, and these bands, preventingthe water passing through the wire fabrics into the cylinder, limit the width of the sheet of paper-pulp. I also use improved buckets for supplying the paper-pulp and water to the machine, and improved mechanism for operating said buckets.
In the drawings, Figure 1 is a plan with portions of the upper parts removed, and Fig. 2 isan elevation of the machine. m
Above the pulp vat or chest E, in which the cylinder A revolves, larrangeia series of suitable V bearings for the reception of wire leading-rollers a I) c d e f. The cylinder A is covered with a coarse-wire fabric, instead of its usual fine-wire-fabric cover, and I usea long belt or web .of wire fabric, S, which passes over the cylinder A and rollers a b 0 cl 6, the roller f being placed in its proper bearings externally after the wire belt S has been put in place. The rollers d and e regulate the tension-of said wire belt S, both rollers being provided for this purpose with supports or bearings 1 and 2, adjustable by screws. The power to drive the belt S may be applied to either of these rollers. The long fine-wire belt S performs the function of the removed fine cylinder-wire, inasmuch as the said wire belt S, if the machine is started, is made to travel or revolve, as well as the cylinder A and rollers a to f, by means of the wet felt belt F, which receives its revolving or traveling motion by press-roller W.
The cylinder A, which in the former cylinder-machine was loaded by the couch and felt roller B, is in the present machine provided with bearings, which are kept down by setscrews H, which prevent any rising of the cylinder A by means of the tight wire belt S in its revolving travel. The couch and felt roller 13, instead of bearing on the surface of cylinder A, is now carried by the long wire S and by the roller 0, which latter replaces the lower couch press-roller of other machines. The wet sheet of paper-pulp 1?, formed on the long fine-wire belt by the evacuation of water into the cylinder A, is pressed between'the two rollers B O and between felt F and long wire S. The wet sheet of paper-pulp is taken up by the felt F from the long wire belt S, and is automatically carried onto the press-rollers W W. T e couch-press B G maybe weighted at willby weights G, and may be shifted, together with the wet felt F, by means of the adjustable bearings L L, into the mostsuitable position, according to the requirements of 8 5 the paper to be manufactured. By this new arrangement of the long wire belt S ascend ing with the wet sheet of paper-pulp up to the roller 1), and of the couch-press B 0, working with a gradual pressure upon the felt, the sheet of pulp, without the employment of any suction apparatus orvacuum-box, is deprived of water to such an extent that no displacing in the first press W W will take place at the highest pressure, and even if these press-rollers work without any felt covers or man chons. Therefore it is possible not only to manufacture the thinnest paper at high speed, but also to produce thickest card-board in double quantity of first-rate quality.
This machine possesses the eminent advantage of conducting the wet sheet of paperpulp from the couch-press to the first press without requiring for this any special kind of wet. felt.
The machine may .be employed with equal success for making paper or for drying ordesiccating wood pulp.
The width of the sheet of paper-p111 p is regulated and effected in this machine neither by the cover-strap, as in long-wire paper-machines, nor by covering the top wire, as in cylinder paper-machines, but simply by endless and very thin india-rubber bands or straps, which are stretched around the circumference of the cylinder at the ends. These bands or straps are tightly laid around the coarse wire of the cylinder A in any required width, and intervene between the wire cylinder and the wire band. These bands limit the width of the paper by preventing the pulp-waterpassing throughthe wire band S, and the pulp will not deposit upon the wire band, except where the water runs freely through the wire belt. The india-rubber straps do not interfere with the revolving long wire belt S, but formabed or layer for the same on the cylinder A. The india-rubber may be placed within the wire of the cylinder, and the cylinder is made to revolve by the traveling belt S, or otherwise, as desired. These straps or hands, pressed be tween the lon'gwire belt S and the cylinder A, or its under wire, prevent any paper-pulp forming upon the belt S, and also prevent water entering into the cylinderA through them or at the place where they are applied. The packing between the vat or chest and cylinder remains unchanged, so that no loss in pulp may occur.
The water-spout or spray-pipeg extends the entire width of the cylinder A, between this cylinder and the long wire belt S. The pipe 9 effects a double purpose. The water-spray falling removes all pulp from the lower coarse wire around cylinder A between the rubber straps or hands. Aportion of this waterfalls upon and running down the elastic bands arrives at the angle formed at P by the cylinder A and the long wire belt S, and percolates through the long wire belt S in a direction opposite to the water, which passes from the pulp into the interior of the cylinder, thereby removing all superfluous pulp from the long wire belt S beyond the width of the sheet, as determined by said rubber bands. The alteration of paper-width is easily and quickly accomplished by putting on elastic bands of different width. The water from a second water-pipe, 11, is discharged downwardly, and removes all waste pulp from the wire belt S during its travel from the roller 6 to roller f by ejecting the water against the inside of this wire and through to the outside. By this arrangement the undisturbed continuous forma tion of an endless paper sheet is secured.
A further improvement consists in the regulating device for the uniform admission of the paper-pulp and for uniform dilution of the pulp by the spent or waste water. The disk, with its connecting-rod n, causes two buckets, O and D, to make a vertical up-and-down movement, and a tilting motion is imparted to the two buckets at theirhighest point of vertical movement. Bucket O is for the paper-pulp, which enters from the pulp-chest Z by pipe h. Bucket D is for the diluting return-water, which enters by pipe K from the cylinder A. Each bucket has a side wall, 1, adjustable in height by addition or removal of small bars, and a valve in the bottom to admit pulp or water. Each bucket is provided with two projecting pins, m, traveling between guides 12 o. The connecting-rod n, attached to the pins 20, will lift the buckets in a vertical direction until the pins m strike against the closed end of guides 12. The connecting-rod n, continuing its upward stroke, will cause the bucket-s to tilt, the pins or serving as pivots for this tilting'motion, and the contents of the buckets will be emptied into the gutter O at the lowest point of stroke of connecting-rod a. The buckets O D are below the level of pulp or water, and the buckets therefore, in being raised above the level, are filled up to the upper edge of their side wall, I, which upper edge is made adjustable. The bucket therefore will only lift and empty into gutter O by the tilting motion such quantity of pulp or water as is required for the paper and proper working of the machine. With this regulating device there is no formation of foam or froth, which is so annoying with scoopwheels, the buckets working quietly at about ten strokes per minute. The diluted pulp is conducted by the gutter 0 into the cylindrical knotter R by the small gutter O, and enters from this knotter into the vat or chest E of the cylinder A, where the formation of paper takes place.
The presses and drying apparatus necessarily connected with this paper-making machine may be constructed according to any wellknown devices.
I claim as my invention- 1. In a paper-making machine, the combination of the cylinder A, a coarse wire-covering, and rubber bands or straps upon the same, and the belt of fine-wire fabric S, substantially as set forth.
2. In a paper-making machine, the combination, with the cylinder A and belt of felt F, of the belt of fine-wire fabric S, the rollers a b f, the rollers d e andtheir screws, for regulating the tension upon the wire fabric S, and the rollers B 0, between which the web of paper-pulp is pressed before passing off upon the felt fabric, substantially as specified.
3. The rubber bands or straps upon the cyl inder A, in combination with the coarsewire covering to said cylinder A, and the belt of fine-wire cloth S, whereby the width of the dea 5, posited web of paper-pulp is regulated, as set ter, and the vat L and pipe K, in combination with the pair of buckets O D, a connecting-rod, 2o
n, for lifting said buckets, a pin and slide, V, for tilting the same and discharging the pulp and water, substantially as specified.
6. The buckets G D, constructed with side walls, Z, adjustable in height by small remov- 25 able bars, whereby the quantity of pulp and water to be raised at each upward movement is regulated, substantially as set forth.
In testimony whereof I have hereunto set my hand, this 29th day of October, 1883, in the 30 presence of twosubscribing witnesses.
