ROLLING-MILL BEARINGS.-

Application filed January 24, 1928. Serial No. 249,075.

This invention has reference to new and useful improvements in bearings 0r brasses for rolling mill rolls and particularly to that i type of rolls employed in mills for rolling 5 sheets, tin plate and the like.

The invention has for its principal object to improve the manner of maintaining the upper and lower hearings or brasses against endwise as well as sidewise movements.

A stillfurther object is to provide the top and bottom brasses for the rolls with means to prevent endwise as well as sidewise move ment of these brasses.

The foregoing objects are obtained by means ofwhich the weight of the materials are reduced, the cost of mill practice is lessened and the practice of changing the several bi-asses made more easy and expedient.

That the invention may be more fully understood, reference is had to the accompanying drawings, forming part of this description, illustrating preferred embodiments of the invention, in which Fig. 1 is a. vertical sectional view through a rolling mill embodying the invention, said section being taken through the necks of the rolls and looking toward the adjacent hous- Fig. 2 is a vertical sectional view, as'the same would appear if taken on the line 2-2 Fig. 1, looking in the direction of the arrows;

Fig. 3 is a detail in plan, partly in section, showing a bearing or brass, such as would be used for the top or bottom roll;

Fig. 4 is a perspective view of the brass shown in Fig. 3', and

Fig. 5 is a view somewhat similar to Fig. 3, but showing a modified form of top or bottom brass.

any usual and well known construction, and

the rolls 2 may also be of any usual and well known construction, provided with necks 3 and fillets 4 at the intersection of the neck and roll.

The upper and lower hearings or brasses are designated respectively, 5 and 6, the former adapted to be seated in a pocket or recess 7 in the overlying rider 8 and the latter adapted to be seated in a pocket or recess 9 formed in the housing 1. These brasses 5 and 6 are preferably rectangular in form, one end of each being abruptly squared, whereas their opposite ends are beveled or inclined, as at 10, and such beveled ends of these brasses are disposed next adjacent 'the fillet portions of the rolls but spaced therefrom, see Fig. 2, to provide the pocket-like spaces 11 in which to place a heavy grease lubricant, if desired. The brasses are formed with concave surfaces 12 to receive complementary surfaces of the roll necks and their sides are shouldered, as at 13 throughout their length, which terminate at the opposite corners of the brasses in off-set or laterally disposed lugs 14. The pocket or shaped walls to receive the angularly shaped sides of the top and bottom brasses 5 and 6. This arrangement is best seen in Fig. 3, where the housing 1 is formed or provided, at opposite sides with sets of off-sets, shoulders or recesses 15 to receive the lugs 14. So assemble'd, it will be obvious that the coacting lugs 14 and shoulders 15 at the opposite ends of the brasses 5 and 6 will prevent endwise as well as sidewise movement of such brasses. It may be desirable to limit or stop endwise movement of the brasses 5 and 6, in one direction, by the use of coacting lugs 14 and shoulders 15, as has been described, and to limit or stop endwise movement of the bi-asses 5 and 6, in the opposite direction by tapering or making the shouldered sides 13 of the brasses wedge-shape, as at 16, see Fig. 5, to coact with. similarly shaped walls 17 in the pocket or recess 7 of the rider 8 and in the pocket or recess 9 in the housing 1.,

What we claim is In combination with a supporting member having a wedge-shaped recess formed on each .of its sides and at its end of least width with lateral cut-outs, a brass of wedge-shape conformably fitted in said recess, and lateral lugs on the sides and at the end of the brass THOMAS H. HEACOCK. DONALD W. FREASE.

CERTIFICATE CORRECTION.

H Patent No. 1,718,820. Granted June 25, 1929, to

THOMAS H. HEACOCK ET AL.

It is hereby certified that error appears in-the above numbered patent requiring correction as follows: In the drawings Sheet 1, strike out the lead lines and reference numerals l8; 19; 20; 22; 23; and 24; Sheet 2, for "Fig. 8" read "Fig. 5"; and insert lead lines and reference numerals 10 t0 the beveled'or inclined portion of the brass, and 12 to the concave surface of the brass in the Fig. 8, hereby changed to Figure 5. Cancel sheet 3 of the drawings containing Figures 5, 6, and 7; and that the said Letters Patent should be read with these corrections therein that the same may conform to the record of the case in the Patent Office.
