CLIFTON B. BEACH, OF CLEVELAND, OHIO.

CONTINUOUS ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 370,522, dated September 27, 1887.

Application filed November 22, 1884. Renewed April 6, i887. Serial No. 233,925. (No model.)

To aZZ whom it may concern.-

.Be it known that I, CLIFTON B. BEACH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Rolling-Mills; and I do hereby declare the following to be a description of the same, and of the manner of constructing and using the invention, in suchfull,clear, concise, and exact terms as to enable any person skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawing, forming a part of this specification, the principle of the invention being herein explained,and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My invention relates to an improvement in rolling-mills, particularly to mills for the production of rods, bars, &c., and to that type of mills known as continuous.

It is of great importance that the floor of the mill should be as free as possible from all obstructions and at the same time the mill be a simple and convenient in arrangement and construction.

The drawing hereto annexed shows a plan view of my improved rod-mill.

A represents the engine; B, the main driving-shaft, and O the main pulley fixed thereon. The main driving-shaft is coupled in the ordinary manner directly to the roughing-rolls D.

E is a belt connecting the main drivingshaft B, by pulley O,with the power-transmitting pulley F, fixed upon the first secondary driving-shaft, G. This shaft G is coupled directly to the second stand of rolls, H, in the series of rolls H H H H 11* H H, while the secondary driving-shaft G is coupled in like manner directly to the fifth stand of rolls, H. Belt E passes over pulley F on shaft G and over pulley F on shaft G, thereby independently connecting togethersaid two shafts. Upon shaft G are two pulleys, K K,which, by means of belts ca, connectpnlleys b b with the rollsH and H respectively. Upon shaft G are pulleys K K which, by means of belts a a respectively, connect pulleys b b with the rolls H H This system of belts and pulleys may be continued at pleasure for any desired number of roll-stands up to and including the fin ishing pass. Ibelieve, however, the best prac tice to be to employ not more than six of these stands proper, making the seventh in line the first pass of the finishing-train, as shown.

It will be seen that by belt E I connect pulley F with pulley F",wl1ose shaft G is coupled directly to the finishing-train H. In the fin ishingtrain there may be two or more rolls, as desired.

By employing this system and arrangement it is apparent that without placing the roll stands too far apart there will be sufficient beltroom between shafts G G G for the transmission of power, and also ample length of belt at a a a for the transmission of the power required to run a single stand of rolls. The roughing-rolls D may be placed at any desired distance from the first stand of rolls, H, andI recommend that instead of attempting to automatically feed the billet from the roughingrolls to the stand H the billet be carried down, sheared off if necessary, and stuck into the roll pass at H. From this point onward the billet will, by the aid of the conductors c o, between each stand, pursue its course without handling up to the finishing pass of the train. 4

I have not attempted in the above description to show the relative proportions of the various pulleys with a view to the attainment of that acceleration of speed from stand to stand which actual practice demands. This proportion is determinable by fixed and well-known rules, and the amount of over-feed or underfeed desired will in each casegovern. The descriptions and drawing are simply intended to illustrate what I conceive to be the best ar rangement of this type of mill and my system of belts and pulleys for the transmission of power from a primary source and at the same time imparting to each stand of rolls such acceleration of speed as the case demands.

I claim-* 1. In arolling-mill, the combination, with two driving-shafts belted together, of two driven shafts coupled each to a stand of rolls and inde pendent belts connecting said driven shafts respectively to said driving-shafts, substantially as set forth.

2. In arolling-mill,the combinatiomwith two driving-shafts coupled each to astand of rolls and belted together, of two driven shafts coupled each to astand of rolls and independent belts connecting said driven shafts respectively to said driving-shafts, substantially as setv forth. i

3. In a ro11ing-mill,the combination,with two 5 stands of rolls whose shafts are belted together, of a third stand of rolls located between said two stands, and havingits shaft belted to one of said first named shafts, substantially as set forth.

1o 4. In arolling-mill,the combination,with two stands of rolls whose shafts are belted together, of two stands of rolls located between said firstnamed stands, the shaft of one of said intermediate stands being belted to one of said firstr 5 named shafts,whilc the shaft of the other intermediate stand is belted to the remaining one of said first named shafts, substantially as set forth,

5. In a continuous rolling-mill, the combina- 20 tion, with a single engine and a main drivingshaft, of roughing-rolls actuated by the latter, and a series of parallel single-pass stands of rolls located one in front of another and belted to said driving-shaft, substantially as set forth.

6. In a rolling-mill, the combination, with 2 5 roughing-rolls coupled to the main drivingshaft, of a series of parallel stands of rolls located one in front of another, and roll-stand shafts belted to said main drivingshaft, substantially as set fort.

7. In a .rolling-mill, the combination, with a series of stands of rolls and a series of rollstand shafts each having two or more pulleys, of independent belts respectively connecting a pulley of each preceding roll-stand shaft to a 3 5 pulley of a succeeding roll-stand shaft, sub stantially as set forth.

In testimony that I claim the foregoing to be my invention Ihave hereunto set my hand this 19th day of November, A. D. 1884,

OLIFTON B. BEACH.
