PATENT oFFIcE.

ROLLING- Application led June 11, 1925, Serial No.

My invention relates to a support for the rolls of rolling mills `of the type in which the rolls are not carried by supporting rolls but by bearings intermediate the main bearings of the roll, and journals of reduced diameter. Such intermediate bearin s extend only over part of the perimeter o their journals and the exposed portion of the journal is protected b a cap of resilient material, for instance elt', which is held in position by an arched holder, preferably a U-shaped steel band.

When very thin sheets are rolled, it may happen that the sheet is forced into the interstice at the journal which it is bridging so that longitudinal corrugations will form in the sheets at each intermediate bearing. This drawback is overcome 'according to my invention by'providing on the journal fulldiameter collars resembling those fof aV thrust bearing, which support the sheetaat the journals.

This protecting cap and its holder must not project from the surface of the roll as otherwise the holder would interfere with the free passage of the sheet: metal. and, moreover, it would be rapidlyfworn down and therefore the diameter of the journals is so determined that ,the holder is slightly set back from the surface of the roll.

Preferably the bearinrs are .staggered in parallel and adjacent ro ls as'otherwise the material would not be worked along a continuous line where such bearings are arranged. Y'

In the drawing aflixed to this specification and forming part thereof a/device embodying my invention is illustrated diagrammatically by way of example.

In the drawings- Fig. 1 is an end elevation, and

Fig. 2 is an elevation of a bearing designed according to my invention.

Referring now to the drawings, 26' is a bearing block in which the journal 12 of MACHINE.

36,440, and in Germany December 21, 1923.

a. roll 2 5 is carried by means of a semicircular brass 15. Two collars 27, 28, are formed on the journal, their diameter being equal 4to the diameter ofthe roll 25. A holder 29 is placed over the journal and cut open 5U for the collars 27, 28, so that it is subdivided into three arches, and a felt cap is inserted between each of said arches and the journal as indicated at 30 for the central arch. The arches are integral with a strip 31 on both 55 sides of the bearing block, and this strip may be adjusted by means of a bar 32 and a set screw 34. y

The collars 27 and 28 prevent any lagging of the plate between them. It will be understood that the number and width of the collars must be chosen in accordance with given conditions, viz, thickness of plate, length of journal, and pressure exerted.

Instead of connecting both .ends of the strips 21, 22 to a common set screw 24, each strip might be provided with a set screw of its own so thatcach strip may be adjusted separately. This modification is so simple that it will readily be understood by an ex- 7o pert without being illustrated.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications wil-1 occur to a person 75 skilled in the art. f

I claim An intermediate support for the rolls of rolling mills, comprising a. journal of reduced diameter in a roll, a bearing exten'd- 80 ing over part ofthe perimeter of said journal, collars formed on said journal of a diameter equal to that of said roll, caps of resilient material extending over said journal where it is exposed between said collars, and means for holding said caps'in position on said journal. f

n testimony whereof I alix my signature.
