SETTING OR MOUNTING FOR ALL KINDS F REVOLVING DRUMS.

' Application filed November 4, 1924. Serial No. 747,874.

To all wit-0m it may concern:

Be it known that I, ALBIN BERTHOLD IIELBIG, a citizen of Germany,iand resident of Berlin, Germany, have invented certain new and" useful Improvementsin Settings or Mountings for All Kinds of Revolving Drums, of which the following is a specification.

This invention relates to an improved settingor mounting for all kinds of revolving drums, such for instance as are used in furnaces or In drying machines. Heretofore it has been the p'ractice'to provide suchdrums with circumferential bands or rings for rolling contact upon suitable rotatably mounted rollers or supports.

Ithas heretofore been quite diflicult to arrange the guiding surfaces of the drums exactly parallel with the rotatable rollers or supports'as.it is practically impossible to correct errors due to the considerable distance between the guiding bands or rings on the drum. It has been customary to remove the drum and place the same in a lathe and turn wn the guiding surfaces thereof. This, owever, is practically impossible 1n the case of very large drying drums or re- I volving furnaces.

Itis, therefore, the primary object and purpose of the present invention to provide an improved drum setting wherein the above difficulty is effectively overcome. My invention further provides means whereby the supporting rollers for the drum may be very easily and quickly HKhUSlZBCl so as to maintain the contacting surface thereof exactly parallel with the surface of the ring or band on the drum.

In one practical embodiment of the invention, I propose to arrange the rotatable rollers. or supports upon whlch the drum 1s set or mounted, for universal swiveling or pivoting movement so that these rollers w1ll automatically follow the drum 1n any deflection thereof from its true axial position.

It is another object of the invention to provide improved means for continuously and automatically lubricating the various parts of the drum rollers or supports.

l/Vith the above and other objects in view, the invention consists in the improved drum setting, and in the form, construction and relative arrangement of the several parts thereof, as will be hereinafter more fully described; illustrated in the accompanying drawings and subsequently incorporated in the sub oined claims.

In the drawings wherein I have illustrated one simple and satisfactoryembodiment of the invention and in which similar reference characters indicate corresponding parts throughout the several views:

Figure 1 is a diagrammatic view showing a setting for a revolving drum of large capacity, wherein the guide rings or bands on the drum are arranged at a distance of from 10 to 25 meters from each other;

Figure 2 is a view of a portion of the drum having a band thereonpositioned at right angles to Figure 1 and'showing thedrum deflected from its positive normal position as may be occasioned by buckling of the drum due to uneven heating or other causes;

Figure 3 is an enlarged side elevation of one of the drum sets or rollers;

Figure 4 1s a longitudinal section thereof;

Figure 5 is a detail section showing an-.

other guide roller or bearin used at each end of the drum for preventing axial shifting movement thereof; and

Figure 6 is a detail sectional view on an enlarged scale of the drum supporting roller shown in Figure 4;

Referring in detail to the drawings, 5 designates the drum, such as is used in large capacity revolving furnaces, said drum being provided with the guide bands or rings 6 circumscribing the drum adjacent its opposite ends. These rings are engaged upon the drum sets or supports, which in the present instance, are indicated generally at 7 and arranged in pairs suitably, spaced from each other on opposite sides of the longitudinal center line of the drum.

As shown in Figures 3 and 4 of the drawings, each of the drum supports 7 consists of a roller 8 rigidly clamped and secured between the two semi-spherical members 9 by means of the bolts indicated at 10. 'This roller is supported by a suitable roller bearing 11 upon a fixed shaft 12. At opposite sides of the roller inner and outer guide members 13 and 14 respectively, are arranged upon said shaft, said guide members having substantially parallel curved flanges between which the members 9 are movably guided. Spacing collars 15 surround the shaft 12 loetween the members 13 and 14;

The shaft is provided with threaded sections receiving the nuts 16 whereby the parts 13,

14 and 15 are clamped together and rigidly held in fixed position upon said shaft. The inner face of each of the members 9 carries an annular packing ring or gasket 17 of felt or other suitable material havin sliding contact upon the. outer convex su ace of one of the members 13.

The opposite ends of the shaft 12 are supported by bearing pedestals 18, the upper ends of which are bifurcated or slotted to receive the adjustable wedge members 19,

are provided with grooves to receive rollers- 21 and the shaft 12 at each end thereof has a transverse groove 22 out in the underside thereof to receive the upper portions of thes rollers. Thus it will be understood that the shaft at its ends has rocking engagement upon the rollers 22 so that in the adjustment of either of the wedge members 19 with respect to the other, the axis of the shaft may assume any desired angular position relative to a horizontal plane.

As shown in Figure 6 of the drawings, one end portion ofthe shaft 12 is provided with an axially extending oil 'duct 23, the inner end of which communicates with a transverse passage 24 opening upon the periphery of the shaft. The open end of said passa e registers with an orifice 25 formed-in t e hubportionof one of the members 13. Thus suitable lubricating oil may be fed under pressure through the duct 23' and passage 24 for distribution to the various bearing parts of the drum supporting roller whereby the latter ar kept continuously lubricated.

In F igure 5 of the drawings I have shown an oscillatably or universally movable roller 26 mounted upon the upper end of a vertically positioned shaft 27 arranged in a suitable support 28.

The vertically; dis"- posed peripheral face of this roller is adapted to contact with the periphery of .an annular strut member 29 fixed to the end of the drum, and whereby shifting movement of the drum in the direction of its axis is prevented. In this case, a single member 18' is arranged at the lower si e of the roller bearing 11 and co-operates with the flange angular displacement of the guiding ring,

since they may freely pivot or oscillate relative to the fixed shaft 12. Also by properly operating, the wedge members 19, the s 12 can be easily. ad]usted to maintain the desired parallel relation between the peripheral surfaces of the rollers and the faces of the bands or rings 6. Such adjustmentI have found to be of very great importance and to enable such drums to be operated with maximum efficiency and economy while at-the same time materially increasing the durability thereof. 1

From th foregoing description considered in connection with the drawings, the construction, manner of operation-and several advantages of the present invention will be readily understood. While I have herein shown and described a simple and satisfactory embodiment of the invention, it will nevertheless be understood that the device may also be embodied in various other alternative constructions and I' 'accordingl reserve the privilege of adopting all 'suc legitimate changes in the form, roportion and relative arrangement of t e several parts as may be fairly embodied within the spirit and scope of the invention as claimed. 'Iclaim 1. A setting for revolving drums consisting of spaced rotatable'supports, an axis for each rotatable support, and a universally oscillatable mounting between each'rotable support and its axis.

2. A setting for revolving drums consisting'of spaced rotatable supports each universally oscillatable relative to its axis of rotation, and means for adjusting the roller shaft to vary the angular relation between, the axis thereof and the axis of the drum and maintain a parallel contacting relation between the peripheral surface of the roller and the contacting surface on the drum.

' 3. A setting for revolving drums comprising rollers each mounted upon a non-rotatable shaft for universal oscillating movement, adjustable bearin members upon which the ends of said sha ts respectively have rocking engagement, and means for vertically adjusting the bearing members independently of each other to vary the angular relation of the roller shaft with respect to the drum axis and thereby maintain the peripheral surface on the rollerin parallel relation to the contacting surface on the drum.
