PROVISIONAL SPECIFICATION.
Improvements in Adjusting Apparatus for the Rollers of Rolling
Mills and analogous Machines.
I, NICOLAUS BAUER, Manufacturer; of Cölnerstrasse, Düsseldorf, in the
German Empire, do hereby declare the nature of this invention to be as
follows:-
This invention has for its principal object, to provide better' means for raising
and lowering the rollers of sheet' rolling mills and analogous machinés, according
to the distance or pressure required' between the rollers.
The bearings of the upper roller are connected" to screw spindles, as usual, by
means of which they may be lifted or lowered, and each of the said screw spindles
may be turned on its axis by means of bevel wheels, from a horizontal regulating
shaft placed parallel with the rollers and above the same (as usual). On the said
regulating shaft is mounted a loose pulley adapted to be turned by a belt from a
smaller pulley mounted on the axle of the upper roller.
On the regulating shaft is mounted a coupling or disengaging sleeve, carrying
on one of its faces 'a pair of studs or bolts parallel to its axis; the said studs passing
through holes formed in the hub of the belt pulley and being adapted to enter
corresponding sockets formed in the hub of the contiguous bevel wheel. The said
coupling disc is adapted to slide along the regulating shaft by means of a disengaging
lever having its fulcrum on a strap or ring mounted on a boss which is keyed to the
régulating shaft.

1.
If the coupling sleeve be placed 'so that the extremities of the bolts passing
through the hub of the belt pulley enter the corresponding recesses of the adjacent
bevel wheel, while the boss on the opposite side of the sleeve is free from the
sleeve, the pulley will turn the bevel wheel in one direction, and the said bevel
wheel, which is 'loose on the regulating shaft, will turn the bevel wheel mounted on
one of the vertical screw, spindles, and as the wheel gears also in another bevel
wheel fixed on the regulating shaft, rotary motion will be imparted to the said
shaft and to a pair of bevel wheels acting on the second screw spindles.
If the disengaging sleeve be shifted away from the pulley, so as to become
free of the 'bevel wheel, while the teeth or studs on its opposite face enter the
recesses of the fixed boss, the belt pulley will impart rotary motion to the said
boss, and therefore to the regulating shaft, in the opposite direction.
If the two screw spindles turn in one direction, the bearings of the roller axles
will be lifted; if they 'turn'in the opposite direction, the bearings will be lowered.
As the two belt pulleys will always rise and fall together, the belt will retain its
teusion.
The construction may be modified, so as to dispense with the specially arranged
bevel wheels and to use another belt pulley.
In this case the driving shaft or countershaft 'carries a pair of loose belt pulleys,
one of which has a straight belt, and the other a crossed belt. A coupling sleeve
is mounted on the said shaft between the said pulleys, and provided on each face
with sockets adapted to engage with teeth or stuts projecting from the said pulleys.
By means of a hand-levet having its fulcrum in a bracket fixed to the ceiling, the
said sleeve may be shifted to the right or to the left, so as to engage with one or
other of the two pulleys, or to be clear of both. As the two pulleys turn in

page_text: opposite directions, and the coupling sleeve is connected with the shaft by groove
and feather, the shaft may be caused to turn forward or backward by shifting the
sleeve to the right or to the left.

Improvements in Adjusting Apparatus for the Rollers of Rolling
Mills and analogous Machines.
1, NICOLAUS BAUER, Manufacturer, of Cölnerstrasse, Düsseldorf, in the
German Empire, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The appliances generally employed for raising and lowering the rollers of sheet
rolling mills have the drawback of being too complicated and inconvenient to
handle. This invention is designed to accomplish the same objects by simpler
and more efficient means, and is illustrated by the accompanying drawings, of
which
Fig. 1 is an end view of a rolling mill; Fig. 2 a partial side view of the same;
Fig. 3 shows the disengaging gear on a larger scale, and Figs. 4 and 5 are
representations of a modification.
The bearings of the upper roller w are connected to screw spindles a, a', as usual,
by means of which they may be lifted or lowered, and each of the said screw
spindles may be turned on its axis by means of bevel wheels b, d, b¹, d¹, from a
horizontal regulating shaft c. On the said regulating shaft is mounted a loose
pulley i adapted to be turned by a belt from a smaller pulley 9 mounted on the
axle of the upper roller w.
On the regulating shaft e is mounted a coupling or disengaging sleeve k, carrying
on one of its faces a pair of studs or bolts k¹ parallel to its axis, the said studs
passing through holes formed in the hub of the belt pulley and being adapted to
enter corresponding sockets formed in the hub of the contiguous bevel wheel e, as
shown by Fig. 3. The said coupling disc k is adapted to slide along the regulating
shaft c by means of a disengaging lever h having its fulcrum ou a strap or ring j
mounted on a boss s, which is keyed to the regulating shaft c.
If the coupling sleeve k be placed so that the extremities of the bolts passing
through the hub of the belt pulley enter the corresponding recesses of the
adjacent bevel wheel e, while the bosss is free from the sleeve k, the pulley i will
turn the bevel wheel in one direction, and the said bevel wheel e, which is loose
on the regulating shaft, will turn the bevel wheel mounted on one of the vertical
screw spindles a, and as this wheel gears also into another bevel wheel d fixed on
the regulating shaft c, rotary motion will be imparted to the said shaft and to the
pair of bevel wheels 6', d, acting on the second screw spindle a'.
If the disengaging lever k be lifted away from the pulley i, so as to become
free of the bevel wheel e, while the teeth or studs on its opposite face enter the
recesses of the fixed boss s, as shown by Fig. 3, the belt pulley i will also impart
rotary motion to the said boss s and therefore to the regulating shaft c, but in a
direction opposite to that mentioned above.
If the two screw spindles a, a', turn in one direction, the bearings of the roller
axle will be lifted; if they turn in the opposite direction, the bearings will be
lowered. As the two belt pulleys g and i will always rise and fall together, the
belt will retain its tension.
The construction may be modified so as to dispense with the bevel wheel e and

page_text: to use another belt pulley. In this case, which is illustrated by Figs. 4 and 5,
the countershaft c' carries a pair of loose belt pulleys, one of which has.
a straight belt and the other a crossed belt adapted to drive pulleys i, i on.
shaft c
A coupling sleeve m is mounted on the shaft c' between the said.
pulleys i, , and provided on each face with sockets m' adapted to engage with
teeth or studs k³, k projecting from the said pulleys. By means of a hand.
lever having its fulcrum in a bracket fixed to the ceiling, the said sleeve may
be shifted to the right or to the left, so as to engage with one or other of the
two pulleys, or to be clear of both. As the coupling sleeve m is connected.
with the shaft c¹ by groove and feather, the shaft c may be caused to turn.
forward or backward by shifting the sleeve m to the right or to the left.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In adjusting apparatus for the screw spindles or pressure screws of rolling
mills, the combination of driving shaft c, and bevel wheels b, d, b¹, d', with fixed.
coupling disc s, loose bevel wheel e, driving pulley i, and a removable disengaging
or reversing gear k, k³, adapted to transmit motion from the driving pulley to
the bevel wheel b either through the wheel e or through disc s, shaft and wheel d,.
substantially as described and for the purpose specified.
C
2. In adjusting apparatus for the screw spindles or pressure screws of rolling
mills, the combination of driving shaft c and bevel wheels b, d, b', d', with a pair
of driving pulleys mounted on same shaft, one having a direct and the other a.
crossed belt, with a countershaft c', a pair of loose driving pulleys i¹, i, a movable-
sleeve m, and means for coupling the said sleeve either with the right or with the-
left driving pulley i, substantially as described and for the purpose specified.
