"Improvements in or. relating to the Grinding of Rolls or other
Circular Work.
We, JOHN HENRY ROYLE TASKER, and JOIN SNOW, both of 29 Sheaf Street,
Sheffield, in the County of York, Engineers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the grinding of rolls or other circular work, its object
being to arrange suitable gearing whereby the rolls when fixed in suitable bearings
on a sliding table are made to revolve and at the same time slide forward and
backwards as desired so that a suitable grinding machine may be fixed up against
the periphery of the rolls and put in operation.
The grinding machine grinds the rolls which are revolved and slide at any
suitable speed, thus dispensing with turning them true as is now the case. If
necessary the grinding machine can also slide in connection with the sliding table
and revolving rolls or other circular work at the same time.
The sliding table with bearings fixed or bolted on for carrying the rolls or other
circular work is placed on a bed with suitable gearing such as, rope, pulley belt
or other arrangements adapted for revolving the work at one and the same time
also for traversing the table carrying the work.
We do not bind ourselves to the form or shape of the pedestals or bearings for
carrying the rolls, or the manner in which we drive the rolls or circular work so as
to revolve and then obtain a true and smooth surface thereon.

COMPLETE SPECIFICATION.
Improvements in or relating to the Grinding of Rolls or other
Circular Work.
We, JOHN HENRY ROYLE TASKER, and JOHN SNOW, both of 29 Sheaf Street,
Sheffield, in the County of York, Engineers, 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:-
This invention relates to the grinding of rolls or other circular work, its object
being to arrange suitable gearing whereby the rolls when fixed in suitable bearings
רנס

page_text: on a sliding table are made to revolve and at the same time slide forward an
backwards as desired, any adjustable grinding machine being brought against th
periphery of the rolls or the like and put into operation to grind them,
In the accompanying drawings,
Fig. 1 is a side elevation of a roll-grinding machine with a portion of th
driving gear removed.
Fig. 2 is a plan of the machine, and
Fig. 3 an end elevation thereof.
Like letters indicate like parts throughout the drawings.
In constructing our grinding machine we place on an ordinary V bed A,
sliding table B and on the same table fix or fasten by any suitable means brackets
or bearings or front and back headstocks C and C and between the centre of same
fix any roll D or the like requiring grinding. At right angles to the bed A or in
any suitable position we place a grinding machine E which can slide forward and
back to its work and is so pivotted that the grinding stones or disc can be placed
at any suitable angle or parallel to the article requiring to be ground. Preferably
the foot or bed E is connected to the main bed A. The grinding machine E can
also if desired be placed on a bed so as to be capable of receiving a traversing
movement in a direction parallel with the length of the bed A. At one end of
the bed A we arrange an extension F for carrying the driving gear such as the
pulleys G, pinion and wheel H and H', the driving bevel wheels K and K' and the
reversing motion wheels L, I and L2 of the screw M for moving the table B.
It will be seen that the motion of the pulley G is conveyed to the bevel
wheels K and K' which rotate the shaft O, and the pinion P at the end of the
latter drives the wheel R for rotating the circular work. Also the action of the
pinion H on the wheel H¹ carried by the spindle H2 operates the wheels L L L³;
the wheels L' and L2 are fastened on the main screw G for traversing the table B
and between the said wheels L' and L3 is a clutch T operated by levers T and T
on a spindle T3. In any suitable position we arrange a reversing handle V on the
bed A with spindle V and lever a connected by connecting rod V3 to lever Von
spindle T3 so that the clutch arrangement is directly operated by the motion of the
handle either one way or the other.
In connection with the same handle V we may arrange any suitable knocking
off self-acting arrangement attached to the sliding table so as to automatically
regulate the distance through which the table slides either one way or the other.
The grinding disc E2 of the grinding machine E is in motion at the same time
as the roll or circular work is revolving and is so arranged that the table B carries
its work backward and forward, endwise, acording to the wish of the operator.
The work is fixed in front of the grinding machine and any suitable standard
pedestal or other bearing can be fixed on the sliding table and if necessary the
table may have a series of grooves for holding T headed or other suitable bolts
for securing the bearings or its work thereon; we wish it understood also that flats
or faces on shafting having cylindrical ends can readily be ground in this machine.
Having now particularly described and ascertained the nature of the said in-
vention in what manner the same is to be performed we declare that what
we claim is:-
1. In a machine for grinding rolls or other circular work a sliding table carrying
devices which support and rotate the work substantially as and for the purpose
described and illustrated in the accompanying drawings.
2. A grinding machine for rolls or other circular work adapted to impart rotary
motion to such work as well as to the grinding disc substantially as and for the
purpose described and illustrated in the accompanying drawings.
3. In a grinding machine the combination with a sliding table such as B
carrying devices which rotate the work in the manner described of a sliding table
which moves the grinding tool in a direction parallel to the axis of rotation of the
work.

page_text: 4. The combination and arrangement of parts constituting the complete grinding
machine substantially as and for the purpose described and illustrated in the
accompanying drawings.
