PATENT OEEIcE- IDIVARDS, OF IVORCESTER, MASSACHUSETTS, ASSIGNOR TO MORGAN CONSTRUCTION COMPANY, OF WORCESTER, MASSACHU- SETTS, A CORPORATION OF MASSACHUSETTS.

ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 766,434, dated August 2, 1904.

Application filed December 3, 1903. Serial No. 183,675. (No model.)

1'0 rtllwhom, it nuty concern.-

Be it known that I, V-Io'roR E. EDWARDS, a citizen of the United States, residing at \Vorcester, in the county of \Vorcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Rolling- Mills, of which the following is a specification, accompanied by drawings, forming a part of the same, in which- Figure 1 represents a plan view of a pair of rolls of a rolling-mill with the housing and a semicircular repeater, showing my invention. Fig. 2 represents a sectional view of part of a repeater embodying my invention, taken on the plane of the lines 2 2, Fig. l; and Fig. 3

is a sectional view of a part of a repeater em bodying my invention, taken on a plane similar to that of Fig. 2, but with the switch-block revolved, thereby changing the angle of the side of the repeater at that point.

Similar reference-figures refer to similar parts in the different views.

My invention relates to means for removing the rod or bar which is being rolled from a repeater in case of an overfeed and consequent tendency of the rod to buckle in the repeater.

Referring to the accompanying drawings, 1 denotes the housing of a pair of rolls in a rolling-mill, in ,which are mounted the rolls 2, to which the rod is fed by the guides 3. The rod upon leaving the rolls enters the repeater 4, shown in this case of a semicircular shape and with its sides 5 preferably at an oblique angle with its bottom 6. The shape of the repeater and the angle of its sides may change, however, without interfering with my invention. At a convenient place on the repeater I form a recess '7, covered with a plate 8, in which recess is join-naled a block 9 on a spindle 10, which is revolved by any suitable means--in the present instance by a pinion 11 and rack 12, which is actuated by a hydraulic cylinder 13 in the usual and well-known manner in machinery of this class.

The block 9 is shown as circular; but the shape of said block is immaterial and may be of any shape whereby different portions of its periphery may constitute successively part of one side of the repeater. The block 9 is shown in its normal position in Fig. 2,.when its side 14: is shown of the same angle as the side 5 of the repeater. In this position the block 9 assists the sides 5 of the repeater 4: in guiding the rod. \Vhen, however, the rod has been conducted by the repeater to a second set of rolls, (not shown in the drawings,) the block 9 may be rotated on the spindle 10, thereby causing the side 15 of the block 9 to form part of the side of the repeater, making an obtuse angle with the bottom 6, so that in case there is an overfeed of the rod it will rise on the side 15 of the block 9 from out the repeater 4:, or it may be drawn out of the repeater by hand, facilitated by the inclination of the side 15, and the danger of its buckling will be obviated.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a rolling-mill, the combination of a repeater having a portion of its side movable, and means for varying the angle which said movable portion makes with the plane of the repeater, substantially as described.

2. In a rolling-mill, the combination of a repeaterhaving a portion of one of its sides movable, said movable portion having faces of different angles with the plane of the repeater, and means for causing said different faces to form successively part of the side of the repeater, substantially as described.

3. In a rolling-mill, the combination of a repeater having a recess in its side, a block journaled in said recess, and means for bringing different portions of the periphery of said block successively to a position in which said portions form part of the side of the repeater, substantially as described.

4.. In a rolling-mill, the combination of arepeater having a recess in its side, a block jour. naled therein making at one portion of its periphery an angle with the plane of the repeater equal to a similar angle made by the side of the repeater, and making at the opposite portion an obtuse angle with said plane of the repeater, and means for revolving said block,

whereby said portions become successively part of the side of the repeater, substantially as described.

5. In a rolling-mill, the combination with a repeater, of a movable member at one side of the repeater and having one of its sides forming an obtuse angle With the plane of the repeater, and means for moving said member into the path of a rod or bar passing through [0 said repeater, substantially as described.

6. In a rolling-mill, the combination With a repeater, of a movable lifting member pro- 7 vided with a lifting-surface forming an obtuse angle with the plane of the repeater, and means for moving said lifting-surface into the path of a rod or bar passing through said repeater, substantially as described.

Dated this 30th day of November, 1903. VICTOR E. EDWARDS. Witnesses:
