PAPER-MAKING MACHINE.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed July 24,1905. Serial No. 271,116.

T all whom it may concern.-

Be it known that JAMES D. PIoKLEs', deceased, formerly a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, did invent a new and useful Improvement in Paper-Making Machines, of which the following is a specification.

The invention relates more especially to that class of paper-machines employing a cylinder over which the web of paper passes in the operation of drying; and the object of the invention is to provide simple and effective moans for causing the uniform drying of the web of paper as it passes through the machine; and a further object of the invention is to provide a device which may be attached to completed paper-machines without in any way altering the mechanism of said machines. A form of device in the use of which these objects may be attained is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a portion of a paper-making machine, showing the improved regulator applied thereto and with the star-wheels inoperative. Fig. 2 is a detail, view in horizontal section, through the improved regulator on the axis of the driving-shaft and with one star-wheel in position to be engaged by a wiper. Fig. 3 is a detail view, in vertical section, through the same on the axis of the driving-shaft.

In the accompanying drawings the numeral 1 dene es a portion of the frame of a paper-making machine. AThis frame supports, among other parts, anumber of dryingcylinders 2, two only of which are shown herein, and-about which the web 3 of paper passes in its travel through the machine and y which it is dried. A tension-roller 4 is mounted in the frame of the machine, as by means of hangers 5, depending from a hollow rock-shaft 6. This rod 6 is mounted at each end in the side parts or brackets 6'l on the frame of the machine, and preferably two of the hangers are employed, one located near each end of the shaft for supporting each end of the tension-1 oll 4. The hangers 5 are secured to the rock-shaft 6, which has a rocking movement in its bearings in the frame, so that the tension-roller 4 may be moved by the pressure of the web of paper 3 thereon, which pressure of course will depend upon the amount of moisture in 55 the paper at this point.

The tension-roll 4 has at one end argear 7 'meshing with a gear 8 on a shaft 9, extending through the rock-shaft 6. A regulatorframe 10 is secured to the hollow rock-shaft 6o 6, preferably outside of the frame 1 of the machine. This frame has a gear-case 11 at one end and an extension 12 therefrom and a pendulum-support 13, extending upward. A pinion 14 is secured to one end of the shaft 9 Within the gear-casing 11, this pinion meshing with a pinion 15, which in turn meshes with a pinion 16, located within the gearcasing 11. The pinion 16 bears a wiper-arm 17, on which is secured a wiper 18, arranged to strike star- wheels 19 and 20, mounted on a screw-threaded shaft 21. This shaft 21 is suitably mounted in the frame 11 in extensions therefrom, as shown, and bears a threaded nut 22, meshing with the thread on the shaft 21. This nut bears a pendulumactuator 23, which is in the form of a slotted plate, the slot in which receives the pendulum 24. A cord 25 extends from the nut 22 around suitable pulleys or sheaves 26, that may be arranged in any desired manner to a valve-lever 27 of a valve 28. This valve 28 is located in a steam-pipe 29, which conducts steam or heating medium to the cylinders 2. The connection to these cylinders is of the usual well-known form common to machines of this class, and further illustration and description therefor are deemed unnecessary herein. A weight-support 30 depends from the frame l0, on which are located weights 31 for holding the roller 4 against the web 3.

The pendulum 24 is pivoted to the pendulum-support 13, depending therefrom and having at its llower end abob 32. The penlulum 24 extends on opposite sides of the screwshaft 21 and engages a sleeve 33, that has a lengthwise sliding movement on the shaft 21, but imparts rotative movement thereto. The star-wheels 19 and 2O are secured to this sliding sleeve. As the frame 10 moves under the influence of the pressure of the web of paper 3 on the tension-roller 4 the bob 32 will cause the sleeve 33 to be moved along the shaft 21, causing one or the other of the 105 star-wheels 19 or 2O to be placed in the path of movement of the wiper 18.

The operation of the device is as follows:

IOO

As the web of paper 3, traveling through the machine in the direction indicated by the arrow, Fig. 1, passes the last drying-cylinder it is tested until `found to be of the proper degree ol dryness, when weights 31 are so placed upon the weight-support 30 that the pendulum 24 will be so located that the wiper 18 will strike neither of the star- wheels 19 or 20. l/Vhen the web of paper passing the cylinder is of the proper degree ol: dryness and the pendulum 24 is in the position described, the

regulator is in proper adjustment 'for controlling the heat ol" the cylinders 2 to keep the web of paper at the proper degree of dryness. The condition of the web at the point of location of the tension-roller 4 of course governs its condition as to dryness when it leaves the j last cylinder, and should the web become too wet at said roll 4 by reason of an insuiiicient supply of heat to the cylinders or by thickening of the web or for any other purpose the tension thereon and. pressure on the roller 4 will become decreased. This will allow said tension-roller to swing to the right from the position shown in F ig. 1, rocking the shaft 6 and lowering the end of the frame 10 opposite the end connected to said rod. This lowering of the outer end. of the frame 1() will move the pendulum-support 13 to the left and likewise the pendulum 24 and the sleeve 33 and star-wheels 1 9 and 2O in the same direction. This will cause the teeth oi' the starwheel 2() to be located in the path of movement ol the wiper 18. This wiper rotates in the direction of the small arrow shown in Fig. 1, so that the star-wheel 20 and the shaft 21 are rotated. The thread. on the shaft 21 is a right-hand thread, and the rotation of the shaft in this direction causes the nut 22 to travel to the right, the nut being held against rotative movement. This draws upon the cord 25, operating the valve-lever 27 to admit steam to the cylinders, causing more heat to be applied to the web 3. In order to prevent travel of the nut 22 along the shaft 21 to an undue extent, the end wall of the slot in the pendulum-actuator 23 will engage the pendulum 24, swinging` it and the sleeve 33 to the right, thus moving the teeth of the starwheel 20 out of the path of movement of the wiper 18. It will be-understood that the cylinders may not becomeheated to dry the web to a suflicient extent before the nut 22 has moved to this point, but that the arrival of the nut at this point will have opened the steam-valve to a sui'licient degree to eventually cause the web to be properly dried. Should the web become too dry, a reversal of the operation just described will be the result and the amount of steam supplied to the cylinders will be reduced. lt will be noted that the rod or support 30 for the weights 31 is secured to a nut 31a, adjustable along'the' threaded shaft 32a, having a hand-wheel 33a. This is for the purpose of securing a Aline adjustment of the weights to regulate the pressure upon the tension-roll, the coarse adjustment being determined by putting on or taking oli weights and the finer adjustment by means of the threaded shaft and hand-wheel, locating the weight nearer or farther from the pivot oi' the frame.
