' forming JPLATE-ROLLIN'G-MILL ATTACHMENT.

Application filed February 20, 1914.

To all whom it may concern:

Be it knownthat we, 'GEORGE DIEFENBACI'I and HARRY WALDORF, citizens of the United States, residing at Granite City, Illinois, have invented a certain new and useful improvement in Plate-'Rolling-Mill Attachments, of which the following is a'full, clear, and exact description, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, part of this specification, in which 1 I Figure 1 is a vertical section taken through the central portion of a plate rolling mill, and showing our improved scale removing attachment combined therewith. Fig. 2 is a rear elevational view of a rolling mill with our attachment applied thereto. Fig. 3 is a detail section taken approximately on the line 3 3 of Fig. 2, and showing one of the adjustable bearings for the rotary brushes forming a part of our improved rolling mill attachment. Fig. 4 is a view similar to Fig. 3, and showing the position of the adjustable brush hearing when the same has been moved to bring worn brushes into contact with the surface of the plate.

Our invention relates to a brush attachment for plate rolling mills, the principal object of our invention being to arrange brushes on the discharge side of a plate roll-- ing mill, for the purpose of removing the scale from the surfaces of the rolled plates immediately after the latter pass from between the rolls.

In the manufactureof rolled metal plates, the billets from which the plates are rolled are heated prior to their passage through the rolling mill, and in heating, scale due to OX- idization is formed on the surfaces of the billets and the proper time to remove this scale is immediately after the plate has been passed between the rolls the first time, or before it is re-rolled. It will be understood that each plate is passed several times between the rolls and the scale, if allowed to remain onthe plate, is gradually pressed into the surface of the same, and if this scale is later removed accidentally'or otherwise, it leaves a depression or thin place in the plate, thus making said plate defective. To overcome this objection we propose to arrange metal brushes adjacent to the rollers, and on. the discharge side thereof, which Specification of Letters Patent.

Serial No. 819,944.

brushes are adapted to engage both upper and lower faces of the plate andremove the Patented Apr. 20 1915.,

scale in the opposite direction to that in which the plate is traveling. Where rotary .brushes are used the same are caused to rotate in the opposite direction to that of the rollers of the mill, so that the plate in emerging from between said rollers will contact with the brushes, so that the scale will be brushed off said plate in the direction opposite to that in which It-is obvious that if the brushes are stationary the plate in passing between them will have the scale removed in the opposite directionto that in which the plate is traveling.

With the above and other objects in view, our invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed.

Referring by numerals to the accompanying drawings, 10 designates the frame of the rolling mill, 11 the rolls thereof, 12 the table or support for the sheets as they are delivered to the rolls, 13 a transverse bar on the rear side of the mill, to which bar is attached a series of guide bars 14 which project toward the rolls and which support the sheets after the same have passed between the rolls.

Pivotally mounted on the main frame of the mill and on the discharge side-of the rolls is a pair of plates or bearings 15 in which are journaled the ends of rotary brushes forming a part of our improved attachment, said brushes comprising shafts 16 to which is applied in anysuitable manner steel bristles. The upper one of these rotary brushes is arranged so that the ends of its bristles travel through a path which is directly above the upper edges of the guards 14 while the lower brush is arranged sothat its bristles pass upward between the guard bars 14, and thus the upper and lower surfaces of the sheets passing over the guard bars are engaged by the ends of the bristles of both brushes. 1

Connected by ball and socket joints to the upper end of one of the bearing members 15 is the inner end of a screw rod 17, the same passing through an adjustable bearing 18 located on the frame of the mill, and the said plate is traveling.

outer end of this screw rod is provided with has can be varied so as to change the position of the brushes and compensate for the wear upon the bristles thereof.

the upper'one of the shafts 16 near the end thereof.

1 The chain 21 is operated so as to drive the brushes toward each other and toward the rolls 11,-and as the plates emerge from between the rolls, their surfaces will be engaged by theends of the steel bristles, and

I 4 all scale will be removed from said plates.

As the ends of the steel bristles of the brushes wear off the screw rod 17 is manipulated to change the angularity of the members 15, and thus the brushes can be retained in service until the bristles are comparatively short. (See Fig. 4.)

An attachment of ourlimproved construction is comparati ely simple, can beadvantageously used inconnection with all forms of plate rolling mills and is veryeffective in removing scale from the surfaces of the pdpites or sheets which pass through said It is obvious that various changes in the size,-form and construction of the various parts of our improved attachment may be made and substituted for those herein shown and described, without departing from the spirit of our invention, the scopeof which is set forth in the appended claims.
