IMPROVEMENT IN GUIDES FOR RCLLING-MILLS.

Specification forming part of Letters Patent No. 144,633, dated November 18, 1873; application filed J une 24, 1873.

CAsE C.

To all whom it may concern:

Be it known that I, CHARLES H. PERKINS, of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Bolling-Mills; and I do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Fig. 1 is a top View. Figs. 2 and 3 are, respectively, front and rear views. Fig. 4 represents the bar before it enters the rolls The invention hereinafter described consists in the employment of a guide of peculiar construction, in combination with the rolls of a rolling-mill, the said guide being so "construoted that the rolled bar passing from the rolls shall cause the guide to hug closely be tween its walls the portion of the bar just entering the scores in the rolls.

In the drawings, A A represent a' pair of rolls for rolling iron, mounted in suitable 'housings, in the usual way, and which, being well understood, require no special description. B B constitute together the guide for the iron entering the score in the roll. The said guide is composed of two bars, whose inner faces are grooved, channeled, or shaped to suit the particular form of iron bar to be rolled. They are pivoted at their front ends to a platform or fixed table, 0, so that their ends nearest the rolls can slide on the surface of the platform toward, or away from, each other, the bars B B turning on their pivots a a as centers. Springs 1) b are applied in any convenient way to these bars, so that the tendency of the bars will be to separate from each other and permit the easy presentation of the end of the bar to the rolls In combination with the said guides is a palr of tongs, D 1)], consisting of two levers pivoted ate 0 to a cross-rail of the B B. The rear arm, E, stands directly over. the score between the two rolls, so that the bar of iron, as it issues from the rolls, will press upward against the end of the arm E as the iron runs over the receiving-platform F,

and cause the wedge projection e to spread.

apart the upper end of the tongs D D. The shape of the end of the arm E should conform to the shape of the rolled bar, and it may be provided with friction-rollers, if preferred.

While I prefer the bent lever or arm E E to be operated by means of the bar of iron rolled, so as to cause the guide B B to compress the iron entering the rolls, it is evident that the compression of the guide can be effected by means of a treadle connected with the arm, or, by other well-known mechanical means, be under the control of the operator.

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

1. In combination with the rolls A A of a rolling-mill, the compressguide B B, the tongs D D, and wedge e, substantially as described.

2. The combination of the compress-guide B B, the tongs D D, the wedge e, and its operating-lever E E, so arranged that abar passing through the guide will, by contact with the wedge operating lever, compress the rod within the guide, substantially as described. CHARLES H. PERKINS. Witnesses:
