JOHN R. KENNETT, OF TROY, NEWV YORK.

CYLINDER PAPER-MACHINE.

SPECIFICATION forming part of Letters Patent No. 777,345, dated December 13, 1904.

Application filed April 18, 1904;,

To all 2071/0111 it may concern:

Be it known that 1, JOHN R. KENNETT, a citizen of the United States, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Cylinder Paper-lllachines, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings and the reference characters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figures.

Figure 1 of the drawings is a top plan view of the cylinder end of a cylinder paper-making machine embodying my invention, the felt being removed. Fig. 2 is a vertical cross section of the same, taken on the broken line 2 2 in Fig. 1. Fig. 3 is a vertical longitudinal section of the same, taken on the broken line 3 3 in Fig. 1 with the felt in place.

The object of the invention is to adapt a cylinder paper-machine to cause the felting or intertwining of the fibers in the paper formed thereby. This I am able to accomplish by imparting to the cylinder, couch-roll, and neighboring portion of the felt a to-andfro rocking motion endwise of the cylinder and roll and transversely of the felt.

Referring to the drawings, 1 represents the vat, 2 the cylinder, 3 the couch-roll, and f the felt, all substantially the same as in the ordinary type of cylinder paper -maehine. The ends of the shaft 5, upon which the cylinder is fixed, fit loosely in and are movable endwise through apertures in the main side walls of the vat, through which apertures they project into the space inclosed by the boxes 6 outside the main vat at opposite ends of the cylinder. The journals of said cylinder-shaft are mounted in bearing-boxes 7, each swiveled upon the upper end of a vibratory arm 8, pivotally mounted at its lower end at 9 upon the bottom of one of the boxes 6. Longitudinal movement of the journals in their bearing-boxes is prevented by means Serial No. 203,610. (No model.)

of the collars 10, [ixed upon the cylinder-shaft on opposite sides of each bearingbox. One of the vibratory arms 8 is connected by means of a pitman 11 with a crank 12 on the shaft 13, located outside the vat and adapted to be driven by means of a belt 14:, engaging a pulley 15, fixed thereon. The pitman passes loosely through an aperture in the outer wall of the neighboring box 6. Operation of the power-shaft 13 thus causes a vibratory or rocking movement to be imparted to the arm 8 with which the pitman is connected, which vibratory movement is transmitted by the cylinder-shaft to the other arm 8 at the opposite end of the cylinder. The cylinder being fixed upon its shaft partakes of said vibratory or rocking movement. Mounted upon the bearing-boxes 7 in fixed relation thereto, respectively, are posts or brackets 16, in the upper ends of which are journaled the opposite ends of the couch-roll shaft 17, which shaft is prevented. from endwise movement in its bearings by means of the collars 18, fixed upon the shaft on opposite sides of its bearings. The couch-roll is lixed upon its shaft, and the posts 16 form rigid connections between the bearings for the cylinder and couchroll, so that as the cylinder-Snpporting arms 8 are vibrated in the manner above described both the cylinder and couch-roll are caused to partake of such vibratory movement without disturbing their relative positions. The felt being passed around the couch-roll, that portion of the felt which is adjacent to the couchroll will also partake of such movement without disturbing the relative position thereof.

The bearing-boxes 20 for the couch-roll shaft may be mounted in vertical slideways 21 in the posts 16, res 'iectively, and each of said bearing-boxes may be forced toward the cylinder to produce pressure between the couch-roll and cylinder by means of an overhanging lever 22, provided with a weight 23 and adapted to engage the upper side of said bearing-box.

As the felt travels over the couch-roll and the couch-roll and eylind er are rotated in the operation of the machine the vibratory movement imparted in the manner above described causes a displacement of the fibers of paperstock on the surface of the cylinder and felt transversely of the general direction of movement of such fibers, causing the fibers to be interwoven or intertwined and felted together and resulting in a better and stronger product.

As a means for closing to the passage of the pulp from the vat between the side walls of the vat and ends of the cylinder I provide a flexible or bellows-diaphragm 25, extending from each side wall of the vat to the neighboring end of the cylinder. This diaphragm is permanently connected with the vat-wall, as by tacks or nails 26 inserted through one of its edges, its other edge being held in close engagement with the end of the cylinder without interfering with the rotary movement of the cylinder.

This I am able to accomplish by mounting upon an end portion of the cylinder of reduced diameter a close-fitting hoop 30, which is, however, loose enough to permit the cylinder to turn therewithin, with which hoop the other edge of the bellows-diaphragm is permanently connected, as by rivets 27. It is necessary only that the bellows-diaphragm extend above the level of the pulp in the vat.

The flexible or bellows diaphragms readily adapt themselves to the endwise-shaking movement of the cylinder and at all times form a connection closed to the passage of pulp between the ends of the cylinder and side walls of the vat.

The side walls of the vat are provided with apertures 29 within the areas inclosed by the respective bellows-diaphragms, through which apertures the water which passes to the interior of the cylinder can escape into the respective boxes 6, from which it can be re' moved in the usual manner.

Any known means may be employed to cause the hoops 30 to move in unison with the cylinder in its vibratory or shaking movement. I have shown a series of springs 31 interposed between each of said hoops and the neighboring side wall of the vat, which serve to always hold the hoops against the end portions of the cylinder of larger diameter, said springs contracting as the cylinder moves toward the side wall with which they are connected and expanding when the cylinder moves in the reverse direction.

W'hat I claim as new, and desire to secure by Letters Patent, is

1. In a cylinder paper-machine, the combination with the cylinder; and rockable bearing-supports for the cylinder; of means for rocking said supports.

2. In a cylinder paper-machine, the combination with the cylinder; of a pair of vibratory arms adjacent to the opposite ends of the cylinder; cylinder-bearings swiveled in said vibratory arms respectively; and means for imparting to said arms vibrating movements.

3. In a cylinder paper-machine, the combination with the cylinder; and couch-roll; of a pair of vibratory arms adjacent to the opposite ends of the cylinder; cylinder-bearings swiveled in said vibratory arms-respectively; bearings for the couch-roll fixed respectively to the cylinder-bearing; and means for imparting to said arms vibrating movements.

In a cylinder paper-machine, the combination with the Vat; the cylinder; and means for shaking the cylinder; of a hoop mounted upon an end portion of the cylinder of reduced diameter, said hoop being adapted to permit the rotation of the cylinder therewithin; springs interposed between said hoop and the neighboring side wall of the vat; and a flexible diaphragm connecting said hoop with said side wall of the vat.

In testimony whereof I have hereunto set my hand this lath day of April, 190 i.

JOHN R. KENNETT.
