I JOSEPH STANDRING DRONSFIELD of the Atlas Works, Park Street Oldham in
the County of Lancaster Machine Maker do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR ROLLING OR FINISHING LEATHER
COVERED ROLLERS AND OTHER BODIES AND SUBSTANCES," to be as follows
-
My Invention relates to apparatus specially designed for use in the treatment
or finishing of the top rollers used in spinning machinery but the said apparatus
may be used for other purposes when it is desirable to roll a body or substance to
and fro upon a table In my apparatus a plate 18 reciprocated to and fro over a
table and the rollers are fed in between the table and plate at one end of the
machine and after having been rolled to and fro under pressure of the heavy or
loaded plate are delivered at the other end of the machine The said plate 18
provided with wheels which run upon side rails which can be raised and lowered
in unison in such a manner as that they shall be parallel with the table surface in
ill positions In practice I raise the two rails by means of four cams which act
upon sliding rods which carry the rails, two cams lifting or lowering each rail and
all four cams being operated in unison by means of connected cross shafts which
are coupled together by means of a side shaft which is provided with worms which
gear with worm wheels upon the said cross shafts By turning a hand wheel upon
the said side shaft the two rails are raised or lowered Connected screws or racks
or connected links or levers might be used to raise and lower the two rails Each
rail carries a second rail which can be raised at intervals so as to slightly lift the
plate In practice I hinge these lifting rails to the other rails and form them as
bell crank levers which are acted upon by means of wipers upon a revolving shaft.
The rollers approach the table by means of an incline which determines the rollers
toward a feeder which lifts the bottom roller at the proper time and passes it on to
the table and below the plate at the time that the latter is lifted by the lifting rails
as aforesaid The lifting of the plate also liberates the roller which has been last
treated and the impetus which it has received carries it out The feeder is attached
to a shaft which 18 caused to rock in its bearings by means of a wiper on the same
shaft which effects the periodical movements of the lifting rails
The arrange-
For this purpose
ments for effecting the reciprocations of the plate may be varied

page_text: I employ a lever frame which is caused to vibrate by means of a crank shaft. The
plate is connected by means of links to the upper ends of the two levers of this
lever fraine When hot rolling is required I heat the table by means of a steam
chest or of gas jets or by suitable means The plate can also be heated by
lowering it into contact with the table at intervals or means may be provided for
heting the plate independantly The construction of the apparatus may be varied
by lifting the main rails at intervals. Slides might be substituted for the wheels
upon the table
The rails are adjusted in height to suit the diameter of the rollers
to be operated upon so that the roller being operated upon takes the weight of the
said plate to a suitable extent.

I JOSEPH STANDRING DRONSFIELD of the Atlas Works, Park Street, Oldham
in the County of Lancaster, Machine Maker do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS FOR ROLLING OR FINISHING
LEATHER COVERED ROLLERS AND OTHER BODIES OR SUBSTANCES" and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement and accompanying drawings
-
My Invention relates to apparatus specially designed for use in the treatment or
finishing of the top rollers used in spinning machinery but the said apparatus may
be used for other purposes when it is desirable to roll a body or substance to and
fro upon table In my apparatus a pl te is reciprocated to and fro over a table
and the rollers are fed in between the table and plate at one end of the machine
and after having been rolled to and fro under pressure of the heavy or loaded plate
are delivered at the other end of the machine The said plate is provided with
wheels which run upon side rails which can be raised and lowered in unison in
such a manner as that they shall be parallel with the table surface in all positions
Each rail carries a second rail which can be raised at intervals so as to slightly lift
the plate The rollers approach the table by means of an incline which determines
the rollers toward a feeder which lifts the bottom roller at the proper time and
passes it on to the table and below the plate at the time that the latter is lifted by
the lifting rails as aforesaid The lifting of the plate also liberates the roller which
has been last treated and the impetus which it has received carries it out When
hot rolling is required I heat the table by means of a steam chest or of gas jets or
by suitable means
In order that my Invention may be well understood I will when describing the
same refer to the accompanying two sheets of driwings which are made to a scale
of about three inches to the foot
In the drawings on Sheet 1 Fig 1 represents a Side Elevation and Fig 2 a Front
Elevation of the machine On Sheet 2 Fig 4 is also a Side Elevation with the
gearing removed or left out in order to represent certain other parts more clearly
In the said Figs a 18 the reciprocating plate and b is the table these parts being
represented in longitudinal section in Fig 3 The said table is finished with a
line and suitably smooth surface and forms the top of a steam chest c whereby
the table 18 heated The under surface of the plate a 18 also made true and
smooth This plate is provided with four wheels d d two upon each side of the
plate and these wheels un upon the side ruls e e Each rail is carried by two
rods el el which are mounted to slide in bearings which in the example are formed
in projections fƒ which are cast upon the framing of the machine The lower end
of each rod rests upon a cam g which is fixed upon a shaft h which is mounted in
bearings formed in or attached to the framing of the machine Each of the two
shafts h extends across the machine from side to side and has a cam at each end
the two cams corresponding with each other in form Upon one end of each shaft h

page_text: 18 also fixed a worm segment or as in the example the said segment may be cast
in one piece with the cam which is at the sime end of the shaft A shift mounted
to revolve in bearings (xtends alongside the framing and upon this shaft are fixed
or formed two worms each worm gearing with one of the two worm segments
The shaft is provided with a hand wheel k or a suitable handle whereby the
shatt may be revolved It will be seen that when this shaft is turned motion is
marted to the two shafts and all the four cams re caused to move in unison
and to an equal extent and as the said cams correspond in form the two rails can
be raised and lowered in unison The sud rails aie adjusted to have their top
surfaces parallel with the surface of the table and thus relation with the table is
prescrved when the rails are raised or lowered The plate a is connected by means
of two side links with two levers m m which are secured upon the two ends
of a shaft n which is mounted to 1ock in bearings on the said levers may be mounted
to rock upon fixed studs Each lever is connected by means of a link o with
crank pin p which is fixed to a disc q which is fixed upon a shaft r The said
shaft extends across the machine and has a disc q provided with a crank pin upon
cach end so that when the shaft is caused to revolve a to and fro vibi ting move-
ment is imparted to the two levers m Upon the same shift is fixed a spur
wheels with which gears a pinion upon the main driving shaft t which is revolved
by means of the diving belt pullies u It will be seen that by the described
ari angement of gearing and er mks acting upon the two levers m m a reciprocating
movement is imparted to the plate a and supposing a roller to have been introduced
between the sud plate and the table it will be rolled to and fro upon the latter
The pressure of the plate upon the roller being operated upon is determined by the
load upon the plate and by the adjustment of the height of the two rails e e
The moving lod to impart the desired pressure can be increased or decreased by
adding to or taking from weights which are or can be placed upon the plate and be
kept in position by stud vas indicated by the dotted lines in Fig 2 or if
preferred the plate may be made or be permanently loaded to be of the desired
weight Also by turning the worm shift in the direction which will raise the
two rails the pressure of the plate upon the roller can be reduced, a contrary effect
resulting from lowering the two rails as will be readily understood In the example
the rollers to be operated upon are placed upon a feed board or plate w which is
carried by brackets projecting from the machine and has an inclination toward the
tible b which causes the rollers to determine toward the same as indicated in Fig 4
and by the dotted circles in Fig 1 The bottom roller rests over and upon a
feeder as indicated in Fig 3 The feeder 18 carried by lever arms x¹ which are
mounted upon studs y y which are fixed to the friming One of the sud arms is
provided with an additional am y upon which is mounted an antifriction bowl
A spur wheel 18 mounted to revolve upon a stud and gears with a pinion which
18 fixed upon the shaft already referred to A corresponding pinion fixed upon
the other end of the same shaft gives motion to a spur wheel z¹ which is upon the
other side of the machine so that the two spur wheels revolve in unison Upon a
stud which is secured to the wheel z 18 mounted an anti-fiction bowl at which at
each revolution of the wheel strikes the bowl upon the aim y¹ and by rocking the
arms y causes the feeder x to be quickly rused whereby the roller resting upon
the feeder is projected into the mouth of the space between the plate a and the
table as indicated in Fig 4 It will be seen that the feeder x moves in the arc
of a circle the centre of which is the axis of motion of the arms y y
To admit
of the entrance of the roller it is necess uy that the plate shall be litted before the
roller is projected upward as foresaid this lifting of the plate being accomplished
an the following manner
2
Upon the outer side of each of the rails e e is hinged a lifting rail b¹ the centre
of movement being it b² Eich rail has a downwardly extending arm which is in
contact with the aim c¹ of a bell-crank lever which is mounted upon a stud which
18 fixed to the framing A wiper which revolves with the wheel strikes the
other nim c² of the said lever at each revolution and by depressing this arm causes

page_text: the arm to push the arm of the lifting rail b¹ which then turns upon its centre
at b as indicated in Fig 4 When in its normal position the top surface of the
rail b¹ is about level with or a little below the top surface of the aile but when
the said wiper acts upon the bell-crank lever the top of the lifting rail is raised a
little above the top of the rail e this movement taking place on both sides of the
inachine It will be seen that as the wheels d extend over the two lifting rails
the described movement of these nails lifts the said wheels from the rails e e
whereby the plate a is lifted from contact with the roller which at the time is
being operated upon The actions of the parts are so timed as that the said lifting
of the plate takes place when the plate is near the end of its traverse toward the
right-hand of the machine taking the machine as it stands as represented in
Figs 1 and 4 It will be readily understood that the roller when relieved from
contact with the plate will continue to roll upon the table in the same direction
that is toward the right-hand until it passes off the table and on to the delivery
board w which by preference inclines away from the sud table In the meantime
the plate will traverse toward the left hand the lifting rails remaining in their
higher positions When the plate has commenced or is about commencing to move
toward the right again and is in a position about as represented in Fig 4 the
feeder will be acted upon to lift a fresh rollet and to project it into the space
between the plate and the table The lifting rails will then be lowered so as to
permit the plate to bear upon the roller just fed on to the table by the described
movement of the feeder The stud upon which the said bowl revolves is adjustable
upon the wheel z
in order that the action of the feeder may be timed and
regulated and the studs upon which the levers c¹ c are mounted are adjustable
horizontally to permit of the regulation of the lift of the rails 6' During the
action of the machine a roller is fed into the space between the plate and the table,
the plate is lowered so as to exert a pressure upon the roller, and is moved to and
fro during several revolutions of the shaft r The plate is then lifted to release
the roller which passes off to the night hand, and a fresh rollet takes its place It
will thus be seen that it is only necessary to supply the feeding board with rollers
and to remove those which have been rolled If any or all are insufficiently
rolled they may be replaced on the feeding board The details of the parts for
imparting the reciprocating movements to the plate a and for lifting it at intervals
may be modified or varied If preferred the said plate may be lifted by bodily
raising the rails e e at the required times as for example this might be effected by
acting upon the worm shaft Fig 5 illustrates a modification in the parts which
give movement to the lifting rails The lever c¹ c³ is fixed upon a shaft which
extends across from side to side of the machine and carries at its other end a single
armed lever corresponding to the aim c¹ so that only one wipei 18 required to act
upon the arm c and as a consequence the wheel z on the other side of the machine
might be dispensed with The part which is acted upon by the wiper and the part
which bears against the arm b¹ of the lifting rail are both adjustable in order that
the movements imparted to the lifting rails may be regulated If preferred slides
might be substituted for the wheels d d The plate a may be heated at intervals
by stopping the machine and lowering the plate into contact with the heated table
or independant means may be provided for heating the plate If hot rolling is not
required means for heating the table may be dispensed with
