SPECIFICATION forming part of Letters Patent No. 224,420, dated February 10, 1880. Application filed October 31, 1879.

To all whom it may concern:

Be it known that I, WILLIAM H. GLOVER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Rolling Mills, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part ofthis specifica tion.

My improvement relates to the coupling device between rolls of the same elevation, by which one roll is made to drive another. This has been done by forming the rolls with'one end projectin g beyond the journal-boxes, and forming longitudinal recesses in this end, which receive"inwardly-projecting ribs upon the coupling-box, so as to cause the couplingbox to turn and to communicate rotation to a spindle extending from one roller to another,- said spindle being grooved like the ends of the rollers for the engagement of the couplin gbox, Whichlaps onto both the spindle and roller ends.

It has been impracticable to keep the rolls in exact line, or even a near approximation thereto, so that the coupling is required to be made very loose to prevent binding and strainin g of the parts. The consequence is that (there is a great amount of jarring and wear from the loose motion between the parts, which are necessarily made very heavy.

My improvement consists in supporting the coupling-spindle upon a spring center spindle at each end, said center spindle being socketed in the coupling-spindle and its end entering a center hole in the end of the roll. This construction prevents the ends of the coupling-spindle beating against the ends of the rolls, as well as acting as a support to said spindle. p

In the drawings, Figure 1 illustrates inyinvention part in side elevation and part in section at a. b, Fig. 2. Fig.2 is a transverse'section at a b, Fig. 1.

and, like it, has grooves e, which the ribs 01 enter at the ends of the spindle.

The grooves between the coupling-boxes are 'occupied by distanceestrips F, whose oftice is These strips to hold the boxes D in position. are held in place by wires G wrapped around them. i,

Up to this point there is no novelty of construction.

I will now proceed to describe the points of novelty of which I claim to be inventor.

The coupling-spindle has an axial socket, e, in each end for the reception of a center spindle, H, whose outer end, h, enters a center cavity, 0, of the. end O of the roll, and thus serves to supportthe end of the couplingspindle. i

The center spindle is forced outward, so as to press its end into the center hole of the roll by a spring, I, Whose outer end bears against the shoulder hof the spindle, and whose in- The coupling-spindle is preferably cast on an axial core extending from end to end, and the sockets may be subsequently reamed out to fit the center spindles.

The position of the center spindle may be reversed. Thus it' may be socketed in the roll, and its center h enter a center hole in the coupling-spindle.

The center spindle, H, may be applied without a spring, I, but would not operate equally WILLIAM H. GLOVER.
