page_text: The table elevator consists of a foot plate a figs. 1, 2, 3, upon which revolves
the crank shaft b provided with a toothed coupling b¹ and a notched wheel b². The
crank shaft b with the shaft heads c c¹ and c figs. 1, 2, 3 is connected by means of
the rods d d¹ with the table d³ ³ and also by the rod e and the lever f working in
the footstep with the counterpoise.regulator g.
The spring k figs. 1, 2, 3, provided with catch i and attached to the bed plate h,
Fig. 2, is connected by this catch i with the notched wheel 6 so as to cause it to
engage in the notch when this reaches it by the rotation of the wheel.
Footplate m which has its centre of rotation upon binge m Figs. 1, 2, 3, placed
upon the support ml, works a rectangular piece m³ which presses upon the
underside of the spring for the purpose of raising it, or permits it to descend when
required.
The combination of the above described parts forms the elevator of the rolling
mill table, and of the regulator of the counterweight.
In order that the middle cylinder S may rise and fall in conformity with the
movements of the counterweight it is connected to this latter by levers gg and
shafts vv or v¹ which are threaded and provided with nuts upon their upper ends
by which they are secured to the bearings of the middle cylinder.

easily and smoothly. The guides and a' are fixed betweon the covers wand w
in such a manner that they can rise and fall easily and steadily within the slides of
the mill frame. The adjustment of the brasses is effected by the screws u u' u² u³
and when it becomes necessary the disc and can be taken out and replaced by
thinner ones.
The top cover w Figs. 5, 6 is prolonged at one side and terminates in a cruteli
to hold the shafts which carries the lovers 2 Fig. 2, so that these may rise and
fall with the roller S. The arrangement of the bearings is the same at each end of
the middle roller.
The apparatus is operated as follows: As soon as the bundle of plates or single
plate has passed' between the roller S and the lower roller T, Figs. 2 and 3, and has
been delivered onto the table dd; Figs. 1, 2, 3, the movable clutch n which is
continuously rotating is shifted into gear against the fixed clutch b' which sets
crank shaft b in motion; tho shaft hands cc lift the rods dd and consequently
raise the table until it takes the position d whilst the shaft c² Figs. 1, 2, 3, depresses
rod c and lover f. This lover fraises at its other end the counterpoise regulator g;
so that the counterpoise p rises and thereby causes the middle roller S to press
upon the lower roll T. Meanwhile the notch 1, Fig. 2, of the wheel 6 has arrived
at the point i; the catch i of the spring & Figs, 1, 2, 3 engages in the notch / and
remains there until the plate or plates to be rolled has almost finished its passage
between the middle and lower cylinder. At this moment the catch of the spring k
is released from the notch by pressing down the footplate m³ and the table d
returns to its first position; the weight regulator groplaces itself upon the
counterpoise p which sinks so as to raise the middle roller S against the upper
roller R and the operation recommences.
The middle roller S riscs and descends by means of the above described arrange-
ment of bearings in connection with the counterpoise p, Figs. 1, 2, 3, smoothly,
easily, and rapidly, and that without any injurious strain, so that very thin plates
may be rolled with perfect precision and safety.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
Ist In a rolling mill, the combination of parts forming the elevator of the
table, in connection with the regulator of the counterpoise, consisting of bed plato a
supporting slinft b with shaft heads oc' and c' and bearing coupling band wheel b²;
the rods and o, fulcrum e', lever with crutch end counterpoise regulator g,
spring, foot plate m' with projection acting on spring k, substantially as described
and shewn in the annexed drawings.
2nd. In a rolling mill, the combination of parts forming the new and improved
system of bearings for the middle roller, consisting of brasses y y' y'y' which
encircle the axle of the roll Figs. 3 and 5, the guides and at which pieces are held
together by the covers wand w Figs. 3, 5, 7, bearing projections www³ ³ and
the crutches together with shafts vor v¹ v Figs 2, 3 and 4, with their
screws uu uu all substantially as described and shewn in the annoxed
drawings.
