ANDREW LAMBERTON, OF COATBR-IDGE, SCOTLAND.
TWO-HIGH REVERSING ROLLING-MILL AND LIKE MACHINE.
Application filed October 28, 1911. Serial No. 657,318.
To all whom it may concern:
Be it known that I, ANDREW LAMBERTON, a subject of the King of Great Britain and Ireland, and a resident of Coatbridge, Scotland, have invented certain new and useful Improvements in Two-High Reversing Rolling-Mills and Like Machines, of which the following is the 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 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.
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 cou plings to two shafts parallel with the rolls, but preferably in a horizontal plane and geared together so as to rotate reversely. Alternatively and in cases where the draft is practically invariable, the rolls may be clirectly geared together and one be driven through a shaft and universal couplings 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 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 hous ings 12. The peripheries of these housings are circular and engage counterpart circular tracks 13 in stationary gables 14 made in halves and secured about the housings by king bolts 15. Between the engaging tracks Specification of Letters Patent.
Patented Apr. 23, 1912.
13 in the gables are aps to accommodate arcs 16 of teeth, while projections 17 on the housings entering these gaps engage stops 18 in the gaps, so limiting the travel of the housings within the gables to 180 degrees. The housings are rotated within the gables this prescribed amount by means of hydraulic 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 rotatory housings and stationary gables is of known. form, but its explanation is necessary to the description of the invention.
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 in termeshing 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 the thus mutually balance one another. 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 46 arranged in a position mean to the two alternative positions of the roll so driven.
As explanatory of the act-ion, 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 ISSUED.
and which is now the engaging surface of with the rolls running continuously in the same direction as before but with their relative positions reversed.
lVhat I claim is 1.

5. In a two-high reversing rolling-mill, a pair of shaping rolls, means for rotating the same around a common axis to reverse their relative positions for the purpose described, in combination with a gear shaft lying in a horizontal plane intermediate the planes of said roll axes in working position, an intermediate transmission member and universal couplings connecting the latter at one end to said gear roll and at the other end to one of said shaping rolls.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
