HENRY ROBERTS, OF PITTSBURG, PENNSYLVANIA.

WIRE-ROD MILL.

SPECIFICATION forming part of Letters Patent No. 653,643, dated July 10, 1900.

Application filed February 13, 1900. EerialNo. 5,048. (No model.)

To all whom it may concern.-

Be it known that I, HENRY ROBERTS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Wire-Rod Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows in plan view apparatus constructed in accordance with my invention and adapted to control the wire-rod loop formed between a pair of rolls. Fig. 2 is a vertical longitudinal section on the line II II of Fig.1. Figs. 3 and 4 are on larger scales, Fig. 3 being a vertical cross-section on the line III III of Fig. land Fig. 4 being a bottom plan view of part of the traveling floor. Fig. 5 is a plan view of a modified construction. Fig. 6 is a cross-section on the line VI VI of Fig. 5.

The purpose of my invention is to provide means whereby the rod-loops in a mill for rolling wire rods can be efficiently controlled and prevented from tangling with each other, the advantages of my invention being that the difliculties heretofore existing. are practically eliminated and better results can be obtained than have been possible in prior mills.

In the drawings, 2 2 represent the rolls of a wire-rod mill, between which in practice a rod-loop b is formed bythe reflexing of the rod and its passage from one pair of rolls to the other. In front of the rolls 2 2 is a traveling floor 3, composed of a frame mounted on endless chains or belts or ropes which pass over sprocket-wheels 4 and travel in the direction of the arrow, so that the surface of the floor shall move in a direction leading away from the rolls. The frame is preferably constituted by cross-pieces 5, fixed to the chains and carrying guide-pieces 6 7, spaced,preferably,far enough apart to receive the two arms of the metal loop; The guidepiece 7 is preferably formed with an overhanging portion and with an adjacent depression or groove.

In practice I set a movable floor-section before each of the pairs of rolls whose loops are to be guided. The loops emerging from the rolls pass upon the movable floor-section, the outgoing arm 0 passes along the guide-sections 6, and the returning arm 01 passes along the guide-sections 7, so that the entire loop is perfectly held and guided on the floor, both its arms are kept taut, and all danger of fouling and tangling with other loops on the same floor is obviated.

In Figs. 5 and 6 I show a modification of my invention, in which the traveling floor 3 has only the guide-piece 6 and receives only the primary branch of the loop, while the secondary branch passes along a stationary part 8'of the mill-floor.

I claim 1. A wire-rod mill having an endless traveling guide set in front of a pair of rolls and adapted to laterally guide the outgoing branch of the metal loop formed by and between the rolls.

2. A wire-rod mill having an endless traveling guide set in front of a pair of rolls and adapted to receive from the rolls the outgoing branch of the metal loop formed by and between the rolls; substantially as described.

3. A wire-rod mill having a traveling floor setin front of a pair of rolls and adapted to receive both arms of the metal loop formed by and between the rolls; substantially as described.

4. Awire-rod mill having a traveling floor setjn front of a pair of rolls and adapted to receive both arms of the metal loop formed by and between the rolls; said traveling floor being constituted of endless chains, crosspieces, and guides set thereon; substantially as described.

5; Awire-rod mill having a traveling floor set in front of a pair of rolls and adapted to receive both arms of the metal loop formed by and between the rolls, a guide formed with an overhanging portion, and a groove; substantially as described.
