Application filed December 26, 1923. Serial No. 682,685.

This invention relates to improved type of bearing, and more particularly to a type of bearing for use in connection with papermaking machinery.

One of the principal objects of the in vention is to provide a bearing, such as may be used for supporting the table rolls and the like of a paper-making machine, which is simple in construction, easy of manufacture, long lived, and readily maintained inoperating condition.

Another object of the invention is to provide a bearing for the table rolls, or the like, of a paper-making machine, which is so constructed that easy mounting of the rolls and ready adjustment of the bearings and rolls may be secured, and thatrotation of any one roll will cause positive driving of the remaining rolls.

Other objects and advantages of the invention will be apparent from the description thereof out below, when taken in connection with the accon'ipanying drawing.

in the drawing, in which like characters of reference designate like parts throughout the several views thereof, 1

F 1 is a vertical sectional View through a. form of bearing for the table rolls of a paper-making machine constructed in. accordance with this invention, the section being substantiallyalong the line 11 of Fig. Fig. 2 is a vertical sectional view along the line 2-2 of Fig. 1, looking in the direction of the arrows; and

its showing a preferred embodiment the inventionis illustrated. and described herein as embodied in a bearing for supporting the table rolls which are generally used in paper-making machinery, particularly in the shaking or forming section of a Fourf It is to be under-. I

drinier type of machine. stoochhowever, that the invention is not limited in its application to the precise embodiment shown.

As is well known, in a Four-drinier type machine the stock is flowed onto an endless tion of the machine. These table rolls should rotate, freely at all times, for they are driven solely by the frictional drag of the forming wire as it passes over them. If any roll should stick the drag on the wire would-be increased which is objectionable',' and furthermore the wire as it passes over the surface of this roll would tend to Wear a flat place on it. Table rolls are generally provided with a, supporting shaft or'journalat each end, each journal being so that! it is no longer driven. The wire is therefore unsupported as it should be and defects in the paper may result. These table rolls are often twenty feet or more in length. In practice the forming wire wears out rather quickly and must be replaced every few Weeks. With the ordinary type of machine all of the table rolls are removed when the forming wire is replaced. And it is not very easy, even for skilled workmen, in attempting to remove and replace these table rolls quickly, to replace them without o jamming some of the rolls because of failure to properly enter the journal into the yoke bearing. Furthermore with this gen-' eral typeof construction described it is very diil'icult to keep the parts in alignment,

especially in a shaking type of Fourdinier,

because of the shaking to which the parts are subjected. It is also extremely difficult to keep water out of the bearing, and this causes trouble.

The type of V in is adapted to obviate all of the dilliculties present in bearings used heretofore, Whether of the yoke type, or any other type; for all bearings heretofore used have been subject to certain objectionable defects.

As shown in the drawing this bearing comprises a split housing having a lower body portion and an upper cover portion 11 these two portions. being held together when in operative position by means of suitable bolts 12. This housing 05 adapted for positioning within a yoke bearing which is shown. here is supported from the side, shaking, rail 13 by means of brackets 14, one of which is positioned at each end of the housing eaclr ot' these brackets beingsuspended from the downwardly projecting flange of the suspension plate 16, by means of a bolt 17, the plate 16 being in turn held to the side rail by means of the bolt l8. By means of this construction the housing may be adjusted to any desired positioning for the plate 16 may be turned about the bolt 18 and the bracket 14: may be swung about the bolt 17 and both the plate and the bracket may be locked in any desired pi'isitioning by suit able tightening of the bolts 17 and 18. Extending through the lower end of each bracket is an adjusting screw 20 each of which contacts with, and supports one end of, the housing, suitable up and down move ment of either or both ends of the housing thus being provided for to give further adjustabilit-y. Lock nuts 21 for holding the supporting screws 20 in adjusted position are also provided.

Preferably suitable dowel pins 22 and s3 are provided for locking each bracket and its associated supporting plate in definite adjusted position, after the housing and the bearings therein have been properly adjusted. After the housing and bearings are once suit-ably adjusted this adjustment need not be varied over long periods of time; for the table rolls may be removed and replaced as often as desired over long periods of operation without substantially varying their adjustment relative to each other and with respect to the path of travel of the il'orming wire.

As shown the housing is constructed to receive, in bearing relation, three table rolls; but within certain practical limits any desired number of table rolls may be supported by one housing. The number of table rolls supported by a given housing is dependent upon the. diameter of the rolls, and is also limited by certain practical factors such as the limitations in physical strength of the inar'jcrials used. Andso for purposes of disclosure the housing is shown as supporting only three table rolls.

Mounted within the body portion 10 of the housing are a. number of rollers bearings, there being one more roller bearing than-there are table rolls to be supported and the bearings being so positioned that each table roll is supported by two adjacent bearings. Regardless of how many rolls are supported by a given housing there will be one more bearing then there are table rolls. 'lhe several bearings shown are of the roller type but of course ball hearings or other suitable type of bearings may be used. Each bcaring consists oi? an inner-race 30 which is in the form of a bolt, extending through each side wall of the lower portion of the housing. This bolt is provided at one end with a head 31, and at its other end with a threaded extension 32, upon which is positioned a. suitable nut By proper manipulation of the nuts 33 the bolts 30 may be entirely removed, or properly tightened in position. Surrounding the inner-race in suitable spaced relation therewith is an outer-race or hearing sleeve 35. Positioned between the inner and the outer race are rollers 36, which are held in position by means of suitable retaining rings 3?. Any suitable type of roller may be used, other than that. shown in the drawing, but the type oi roller shown has been 't'oun'd to function very satisfactorily. The bearing sleeve 35 not only constitutes the outer-race and retaining ring .ior the rollers but it also serves as a bearing sleeve to support a rolling load. Supported byeach bearing sleeve. and in rolling engagement with each ot these sleeves, is a. journal roller 4-0, each of which is mounted upon a shaft or journal 41, which shafts are carried by the table rolls 42 at each end thereof. Preferably the journal rollers are of substantially the same diameter as the rolls themselves, and as shown each of these rollers is held firmly upon its accompanying journal shat't by means of a taper fit connection. is is clear from the disclosure of the drawing each of these rollers 40 is supported by two adjacent roller bearings, each roller being in rolling contact with the bearing sleeves of two adjacent bearings. As a result oi this construction it any one table roll rotates its accompanying journal roll 40 will tend to rotate the two bearing sleeve.) by which it is supported, and will thus transmit rotary motion to the two journal rollers 40 positioned on each side of it. and each of these in turn will tend to impart rotary motion to the journal rollers positioned adjacent; to it. Consequently so long as any one table roll rotates the remaining I'Olls which are supported within same housing will also be caused to rotate.

Despite the fact that the table rolls are driven by the forming wire so that end thrust of these rolls would not. he expected, nevertheless there is such end thrust, and as a result during oneration wear will take place. In order to compensate for any such wear and prevent end play, and to take up end thrust which is especially pronounced. of course, where the table rolls are mounted on a shaking forming section, an adjustable thrust receiving bolt do is mounted within the wall of the housing adjacent the end ot each journal shaft 41. By proper adjustment each of these bolts may be caused to contact with the end of its cooperating journal shaft so that it will take up all the thrust. A suitable lock nut 4-6 provided for holding each of these thrust bolts in ad Inn justed position. As shown particularly in Fig. 3 the housing is divided in two horizontal planes to form the upper and lower sections and so the thrust bolts are threadedly mounted within one section.

Preferably each bracket 1 is provided with a bolt 48, which is threadedly mounted within a suitable opening 49, tapped in each of the inner-race members 35 associated with the two end bearings. These two .bolts 48 thus tend to restrain-the housing against movement, and hold it in properly adjusted position.

Each of the inner-race members 30 is provided with a pin 50, which locks each of these inner-race members against rotative movement.

The body portion 10 of the housing is provided with a plurality of upwardly ex tending partitions which divide this lower portion of the housing into compartments, these partitions serving as battles to prevent the flow of oil along the housing when it is in inclined position during operation. During operation the table rolls generally have a surface speed of rotation of about a thousand feet per minute and of course the journal rollers 40 have the same speed. At'this speed of rotation these rollers will pick upplubricant and carry {it on their surfaces, some ofthe lubricant being carried over to the cooperating bearing sleeve and so on the entire length of the housing, and,

some of the lubricant being thrown off from the rotatingjournal rollers. Effective -lubrication of each of the roller bearings and of the contacting rolling faces of the ournal rollers and the bearing sleeves is thus insured. Positionedwithinthe top section of the housing adjacent the last journal roller is av scraper 56, which cooperates with the surface of the last journal roller and serves to strip the oil from it. This oil runs along the inclined surface of this scraper and collects inthe pocket 57. Connected to the bottom of this pocket is a pipe 58, the other end of which opens, as shown at 59, into the bottom portion 10 of the housing. in actual practice it is found that the oil is so scattered, as it is flung off from the rotating journal rollers that uniform distribution of the oil throughout the apparatus with resulting uniform lubrication will be assured, even though the side rail and the housing carried thereby areinclined at a considerable angle. But if the oil should be impelled by the surfaces of the revolving rolls from one end to the other at a rate which would tend to cause an accumulation-of the oil at the lower end of this housing the scraper 56 would strip the oil from this last roll and return it through the pipe 58 to the upper end of-the housing so that a continuous circulation of oil would thus be secured.

During operation, apparatus of this charof the housing be prevented. In order to accomplish this each journal shaft 41 has a sleeve 60 slidably positioned thereon which sleeve is constrained to rotate with the journal shaft by meansof a pin and slot con nectionol; which, however, allows free lon- 1 gitudinal sliding of the sleeve. At that end which is adjacent the housing each sleeve is provided with an outstanding. flange 62, the face of the sleeve andflangebeing machined to cooperate with the corresponding machined surface 63 on the housing. The other end of each sleeve is recessed to overlie the hub of the table roll and a spring 6e1- is positioned within this recessed portion to urge the machined surfaces of the sleeve and housing together. provided with a circular groove 65, to which is connected a passage 68, which opens into the interior of the housing. As a result of this construction there is a tendency tothrow off any water which falls upon the sleeve 60 due to the rotary motion. In addition inward leakage is prevented by the closely fitting surfaces, so thatthe entrance of water into the housing is prevented. Furthermore leakage of oil out of the housing is also prevented for any oil tending to work between the surface 63 and the contacting surface-of the sleeve will be caught .by the circular .groove 65 and .returned to the housing.
