To all whom it may concern:

Be it known that 1, ANDREW Lamnsn'ron, a subject of the King of Great Britain and Ireland, and a resident of Coatbridge, Scotland, have invented certain new and useful Improvements in T wo-Hi h Reversing Roll ing-Mills and like following is a specification.

The invention relates to that type of twohigh reversing rolling mill in which to avoid reversal of the direction of rotation of the rolls they, constantly driven in one direction, are carried in housings which are capable of oscillation through 180 degrees by means of rack and pinion gearing in gable-like end frames (that is, substantial vertical framings in which'are bearings for the housings) so as to reverse the relative positions of the rolls. a

The invention has for its object to provide a simple and effective form of driving gear for such a mill.

In carrying out the invention, the two rolls in a vertical plane one above the other are connected by shafts with universal coulings to two shafts parallel with the rolls, but preferably in a horizontal plane and geared together so as to rotate reversely.

Alternatively and is practically invariable, the rolls may be directly geared together and one be driven through a shaft and universal couplmgs from a driving shaft arranged in a position mean to the two alternative positions of the roll so driven.

In order that the invention and the manner of performing the same may be properly understood there are hereunto appended explanatory drawings illustrative of the carrying out of the invention, Figure 1 being a plan view of the mill operating mechanism; and Fig. 2 a subdivided side elevation; and Fig. 3 an end elevation of a mill of the type referred to provided with an example of the improved form of driving gear; while Fig. 4 is a side elevation of an alternative form of the gear.

In the illustrative example shown in Figs. 1 to .3 and which is of a rail-mill, the pair of rolls 10, 11 (arranged as usual one vertically above the other) are carried in housings 12. The peripheries of these housings are circular and engage counterpart CllClllar tracks 13 in stationary gables 14 made Machines, of which the in cases where the draft in halves and secured about the housings by king bolts 15. Between the engaging tracks 13 in the gables are gaps to accommodate arcs 16 of teeth, while projections 17 on the housings entering these gaps engage stops 18 in the gaps, so limitin the travel of the housings within the gabfizs to 180 degrees. The housings are rotatedwithin the gables this prescribed amount by means of hydrauhc rams 19 operating within cylinders 20 and carrying a toothed rack 21 which gears with a pinion 22 on a shaft 23 which has on it pinions 24 gearing with the arcs 16. This whole arrangement of rotary housings and stationary gables is of known form, but its explanation is necessary to the description of the invention. i

The improved gearing is as follows?- The rolls 10, 11 are driven by shafts 25, 26 through universal coupling devices 27, 28, 29, 30 from two gear shafts 31, 32 parallel with the roll axes but in a horizontal plane the level of which is about midway between the rolls. On the two shafts 31, 32 are intermeshing pinions 33, 34, the whole being arranged in a gear box 35. One pinion shaft 32 is driven from a first motion shaft 36 through a usual short shaft 37 and universal couplings 38. In order that the weight of the shafts 25, 26 may not have to be overcome in turning the housings through the prescribed 180 degrees, they are interconnected with one another by a chain 39 passing over a pulley 40 and connected to stirrups 41 embracing them, so that they thus mutually balance one an other. Alternatively and as shown in Fig. 4, the rolls 10, 11 may be directly geared together by pinions 42, 43 and one be driven through a shaft 44 and universal couplings 45 from a driving shaft 46arranged in a position mean to the two alterative positions of the roll so driven.

As explanatory of the action, let it be considered that the upper roll 10 of the pair of rolls 10, 11 when the housings 12 are in one position, is rotating clockwise, passes are made from right to left as the lower and which is now the engaging surface of that roll is traveling from right to left. The housings are now rotated through 180 degrees. the upper roll 10 has become the lower. It still rotates clockwise but it is now its upper surface which is in engagement. Its

upper surface moves ,fIQIn fleftf to. right. he pass is now from left to right'that is, in opposite direction and that Withthe rolls running continuously inthe same direction as before but. with their relative positions reversed. I claim as my invention i '1.
