GUIDE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 716,259, dated December 16, 1902.

Application filed May 2,1898. b'erial No. 679,481. (No model.)

To all whom it may concern:

Be it known that I, JOHN HENRY MELLORS,

a citizen of the United States,residing at Pittsburg, county of Allegheny, and State of Penn-. sylvania, have invented a new and useful Improvementin Guides for Rod-Polishing Mills, of whichimprovement the followingis aspecification. My invention relates to guides for mills adapted to polish long cylindrical rods or bars, and my improvement maybe applied to any form of. mill in which the rolls are horizontally arranged and an gularly disposed to each other.

The purpose or object of the invention is to produce a guide adapted to support long rods in their passage through the mill and to prevent bending and abrading the surface thereof; and to accomplish this purpose my invention consists in the novel construction and arrangement of parts hereinafter described, reference being had to the a-ccom panying drawings, in which- Figure 1 is an end elevation of a machine embodying my invention; Figs. 2, 3, 4, 5, 7,' and 8, details of the guide parts; Fig. 6, a top plan View; and Fig. 9, a side viewof the rolls, showing how they are disposed with relation to each other.

Referring to the drawings, A B are horizontal rolls mounted in boxes at b and are angularly disposed to each other, roll B having its longitudinal axis inclined upwardly. The said boxes are mounted inthe frame or housing 0 D in such wise that they may be moved toward or from each other, whereby the distance between the rolls may be increased or decreased. This is accomplished by means. of the regulating-screws F F, the outer ends of which are provided with hand-Wheels E E and their inner ends connected to the boxes at b.

The rolls A B are slightly out of horizontal alinement, one of them being convex in contour and the other concave. The inclination of the concave roll B,acting on the rod against the horizontal convex roll A, has a drawing action and causes the bar or rod to be drawn through the rolls during the polishing operation, and the use of these rolls also insures an even feed and a twist-like polishing action on the rod,

Located on the outside of the framing, in

alinement with the space between rolls A B, is the guide G, which is adapted to support the rod or bar in its passage between the rolls from the entrance H of the passage to the exit thereof. H of the passage, and the guide G at the exit I thereof, are secured to the machine-frame in a line intermediate the rolls.

Secured below the passage in both ends of the housing are plates L L, having in their upper part slots K, in which is seated the squared ends of the support-bar J, which is located between the rolls A B and conforms in contour therewith. Forming part of the guide G is a piece M, the lower end of which rests on a part of the plate N on one side of the slot K, and the wall or side of which is cut to conform to the contour of the rod or bar, which is adapted to pass therethrough and which forms a proper bearing therefor. These pieces M M are dovetailed in the guides G G, which permits their ready removal.

The operation of my device is as follows, to wit: The rod or bar to be treated is thrust into the entrance II of the passage, and, due to the fact that the rolls are disposed angularly, it is drawn therethrough by the operation thereof to the exit I of said passage, the support-bar J supporting it on the bottom and the curved upper portion on the piece M holding it on the top.

The shape and disposition of the rolls not only feeds and polishes the rod, but causes it to bend slightly, thus flipping off the scale from the outside of the rod. As the rod goes through the exit-pass it is straightened again.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A guide for rod -mills, comprising the combination, with rolls, of a guide member at the entrance of the pass, another guide member at the exit of the pass, plates secured to the frame of the mill and having slots, and a horizontal support-barseated in said slots and arranged between the'rolls and between the said plates.

2. A guide for rod-mills, comprising the combination, with rolls, o f an adjustable angular member at the entrance of the pass, another adjustable guide member at the exit of the pass, said guide members having guide- The guide G at the entrance ICO pieces with depending portions movably secured thereto, plates having vertical slots therein, and a horizontal support-bar seated in said slots, and adapted to support the rod during the operation.

3. A guide for rod-mills, comprising the Combination, with a frame having concave and convex rolls mounted therein, of guides secured to the frame between said rolls, plates having vertical slots secured to the frame below said guides, and a horizontal rod between said rolls and conforming in contour therewith and seated in said slots.

4. A guide for rodmills, comprising the combination, with convex and concave rolls, of a rod-supporting bar located between the rolls and having its edges of substantially the same contour as the respective rolls.

In testimony whereof I have hereunto affixed my signature in the presence of two sub- 20 scribing witnesses. JOHN HENRY MELLORS.
