UNITED STATES HENRY J. DAVIS, 0F NILES, OHIO.

CONTINUOUS ROLLING MILL.

Application led February To all whomy it may concern.'

Be it known that HENRY J. Davis, citrzen of the United States of America, residing at Niles, inthe county of Trumbull and State of Ohio, has invented certain new and useful Improvements in Continuous Rolling Mills, of which the Yfollowing 1s a specilication.

My invention relates particularly to continuous roller-mills adapted for rolling metal plates and other purposes by successive reductions in a series of mills or rolls.

The principal object is to produce a de vice having a chuck carrying 'a journal.

Another object is to provide a spacer above said chuck.

A still further object is to provide a means of stopping the longitudinal play usually given the rolls when a single mill 1s used.

With these and other objects in view the invention consists in its novel construction, combinations and arrangement of parts in which the drawing shows one embodiment of the invention.

Figure 1 is a side view showing a plurality of rolls as constructed by my invention.

Figure 2 is a detail view showing the chuck, spacer and journal carried by the chuck.

Figure 3 is a detail view.

Figure 4 is a detail view.

By referring to Figure 1 it will be seen that I have set up a plurality of roller mills designated as 1, 2 and 3. These mills are of ordinary construction with the exception of chuck 4 which is located between the boxes which carry the neck 6 of rolls 7. These rolls 7 are caused to turn by ordinary means known'to the art. In the mills as shown in Figure 1 the metal enters the millk 1. This mill -1 is provided with a spacer 8 located between the chuck 4 and the upper boxes 5. The width of the spacer is determined by the degree of reduction desired in passing the metal through the rolls 7. In order that the metal may be carried to the mill 2, it is desired to secure what is known as a Hat delivery, and this is accomplished by using rolls of the same diameter. New the metal rests upon a conveyor 18 which consists of a plurality of small rolls 9 caused to rotate bythe use of a drive 10 7, 1921. Serial N0. 442,981.

which is connected to an extended end 11 of the neck 6 and a drive end oi a roll 12. (See Figure 3.) This roll 12 is journaled in the chuck 4 which is secured within the boxing channel 17 of the housing of the mill. As the metal enters mill 2, the spacer 13 being less in thickness than the spacer 8 allows for another desired reduction of the metal. The metal is now carried to mill 3 by a conveyor 14 similar to the conveyor 18 and is caused to operate in the same manner. A spacer 15 of less thickness than the spacer 13 now allows the metal to be still further reduced. Now in establishing a continuous roller mill of this type, as many single mills may be employed as is necessary to reduce the metal to the thickness desired.

While Figure 1 shows the mills 1, 2 and 3 spaced a considerable distance apart in order to more clearly show the parts, in actual practice'it is better to install the mills quite close together in order to secure the reduction of the metal in the shortest time and with a minimum amount of exposed surface between the mills as it is the purpose of reducing the metal by a continuous pass through the plurality of mills.

By referring to Figure 4 it will be seen I have provided shims 16 placed betweenthe boxing 5 and the boxing channel 17. In order to place boxes 5 which support the rolls 7, in this channel 17 some play must be given and after the boxes are in, the shims 16 are driven in, thus eliminating play of the boxes 5 carrying the rolls 7 which would interfere with a continuous mill type of rolling metal.

What I claim is:

In a device of the class described, a continuous rolling mill, a chuck between the boxes carrying the rolls for the purpose of spacing said rolls and giving support to the ends of a drive journal which drives a conveyor, a spacer between said chuck and the upper boxes shims positioned between the channel in which the boxes are positioned and the boxing, substantially as described for the purpose set forth.

In testimony whereof I allix my signature.
