The adjusting mechanism which we employ Ourinvention relates to the rolling of metal comprises eccentrics 9, which fit around the plates and sheets and is designed to overcome necks of one of the rolls, preferably the upzo many of the difficulties incident to the mills per roll, and are fixed to or connected with heretofore employed, wherein the rolls are worm-wheels 10 at each end of the roll, with 7o continuously rotated. which intermesh worms ll on shafts 12, hav- To that end it consists in a new and iming bevel-gear connection 13 with a shaft 14, proved arrangement of oscillatory rolls with provided with hand-wheel 15, by which the 25 suitable feed-tables, whereby sheet or plate collars 9 may be turned simultaneously, so as metal may be easily and rapidly reduced by to adjust the rolls with great accuracy. back-and-forth motion, as distinguished from To feed the metal to the rolls and receive a continuous rotation. it therefrom, we provide tables 16, having It also consists in the above combinations lower ball races or guides 17, containing balls 3o with means for shifting the tables along the 18, which rest on tracks 19, supported on a length of the rolls, so that the metal will keep frame 20. Each table is moved longitudinally 8o the working portions of the rolls at a uniform of the roll-bodies by a link 2l, terminating in temperature throughout, and thus preserve a yoke or double plate 22, in which are pivthe proper contour of them; and it further oted rollers 23, which bear upon a rod 24.,

Instead of engaging the end members, and these frames these gear teeth other connections may be are connected by bars 28, as shown in Fig. 2, used between the rolls or their shafts. The so that they move together, one frame and talower roll is driven from a crank-shaft 6 by ble moving into the bite of the rolls as the other moves out. This enables the Workman to enter the m-etal'either on the side Where he is standing or on the other side.

To square up the sheets or packs on the table, We provide guides 29, secured to levers 30, one of which is. pivoted at 31 and the, other at 32 to vbrackets secured to the mow, able table. A link 33 connects the levers in i such a way that movement of either lever causes them both to simultaneously move toward or from each other. i

In operating the mill the metal piece or pack is placed upon the table,'which is moved along to any desired point in the length ofi the roll-bodies. The platform carrying ther table is then moved in, so as to enter the l piece or pack. The passing of the metal back and forth may be continued as ymany 'times' as is necessary or desirable, the adjustment of the rolls being varied from. time to time, as desired. As the sheet or pack is passed in this manner through the roll the tables'are moved to different points of the roll-bodies, so -as to keep these bodies at a practically uniform temperature and wear them down uniformly in their different portions. Their. contour is thus preserved of uniform shape, and much of the diiiiculty resulting from unequal heating and Wearing of the rolls 'is avoided.

4The rolls may be made ofthe `formof complete cylinders, theymay be oscillated lby other driving mechanism, such as Worm-gear,

and many other variations may be made Without departing from our invention,
