Year: 1884

page_text: We THOMAS WILLIAM BASSETT MUMFORD of 1 Glendale Villas, Sylvan,
Wanstead in the County of Essex Manager of Chemical Works and ROBERT
MOODIE of 40 Park Grove, Portway, West Ham in the County of Essex Engineer
do hereby declare the nature of said Invention for "IMPROVEMENTS IN APPARATUS
FOR GRINDING OR TRUEING THE SURFACES OF ROLLERS OR THE LIKE" to be as
follows:-
The object of this Invention is to provide an apparatus which can be readily
applied to machines for the purpose of grinding or trueing the surfaces of rollers or
the like without the necessity for removing the rollers or the like from their
housings or bearings.
According to the said Invention an emery wheel is mounted upon a shaft so that
it revolves therewith but so that it can be slidden lengthwise thereon. The said
shaft is carried in bearings in a frame which is provided with means whereby it
can be fixed in position upon the machine the rollers (or the like) of which are to be
ground or trued. Motion of rotation is given to the shaft and consequently to the
emery wheel by any suitable means for example by a band communicating motion
from the axis of the roller or the like being operated upon. At the same time a
traversing motion is given to the emery wheel. This may be effected by means of
a fork engaging in a groove in the boss of the emery wheel the said fork being
traversed by means of a lever or of a screwed shaft operated by a crank or hand
wheel or by other suitable means. The operating parts may be adjustable and
fixable in their frame so as to accommodate the various rollers or the like to be
ground or trued. The Invention is not necessarily limited to emery as the material
used for grinding or trueing, as other suitable material may be used according to
the work to be done. If desired there may be more than one grinding wheel in
each apparatus.

Wanstead in the County of Essex, Manager of Chemical Works and ROBERT
MOODIE, of 40 Park Grove, Portway, West Ham, in the County of Essex, Engineer,
do hereby declare the nature of said Invention for "IMPROVEMENTS IN APPARATUS
FOR GRINDING OR TRUEING THE SURFACES OF ROLLERS OR THE. LIKE" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this Invention is to provide an apparatus which can be readily
applied to machines for the purpose of grinding or trueing the surfaces of rollers
or the like without the necessity for removing the rollers or the like from their
housings or bearings.
According to the said Invention an emery wheel is mounted upon a shaft so that
it revolves therewith but so that it can be slidden lengthwise thereon. The said
shaft is carried in bearings in a frame which is provided with means whereby it
can be fixed in position upon the machine, the rollers (or the like) of which are to
be ground or trued. Motion of rotation is given to the shaft and consequently to
the emery wheel by any suitable means for example by a band communicating
motion from the axis of the roller or the like being operated upon. At the same
time a traversing motion is given to the emery wheel. This may be effected by
means of a fork engaging in a groove in the boss of the emery wheel, the said fork
being traversed by means of a lever or of a screwed shaft operated by a crank or
hand wheel or by other suitable means. The operating parts may be adjustable
and fixable in their frame so as to accommodate the various rollers or the like to be
ground or trued. The Invention is not necessarily limited to emery as the material
used for grinding or trueing, as other suitable material may be used according to
the work to be done. If desired there may be more than one grinding wheel in
each apparatus.
And in order that our said Invention may be fully understood we shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several Figures on the annexed sheets of Drawings, the same letters of reference
indicating corresponding parts in all the Figures.
Figure 1 of our Drawings is a front elevation and Figure 2 is an end elevation
of an apparatus for grinding or trueing the surfaces of rollers arranged according to
our Invention. A are the rollers to be ground or trued and B is the emery or
other grinding wheel. This wheel is fitted with a gun metal or other suitable
bush or boss C and is mounted on the shaft or spindle D so as to rotate therewith
and at the same time admit of its being traversed longitudinally thereon. For this
purpose the bush or boss C is provided with feathers or projections engaging with
corresponding grooves on the spindle, or the grooves may be in the bush and the
feathers or ribs on the spindle, or, if desired, that portion of the spindle over or
along which the grinding wheel is required to travel may be made of a square or
other suitable section to fit a corresponding hole or passage on the bush or boss C
so as to ensure the rotation of the wheel B with the spindle D. This spindle is
carried in housings or bearings E and may be driven at any required speed from
the axle of one of the rollers A or otherwise by means of gearing or by a driving
strap passed round the pulley F. The wheel B which may be driven either in the
same direction or in the opposite direction to that of the roller or rollers upon
which it is acting is caused to traverse along the spindle D when required by
means of the screw G carried in bearings in the frame of the apparatus and rotated
by means of the handle H or by any other suitable device such as the hand

page_text: wheel H. This screw is made to work in a nut fitted to or formed in the forked
piece I the arms or prongs of which embrace the bush or boss C and enter a
grooved part thereof so that the said bush or boss C is free to rotate. It will thus
be seen that upon rotating the screw G in one direction or the other the forked
piece I will be caused to move along the screw G and carry with it the grinding
wheel B. By thus traversing the wheel B to and fro over the surface of the roller
or rollers the surface or surfaces thereof will be maintained in or brought to a
perfectly true and smooth condition and this if desired without removing them
from their position or stopping the machine.
To adjust the position of the grinding wheel to suit the position of the rollers or
surface to be operated upon the said wheel and the operating parts may be carried
in brackets J which can be adjusted (by the screws K.) in the framing L fixed to
the machine with which the apparatus is used. The bolts m are for fixing the
apparatus in its adjusted position.
We do not limit ourselves to the application of this apparatus to the trueing of
rollers in their places, as in some cases it would be desirable to mount the grinding
machine on a light frame suitable for the purpose on which also the rollers to be
trued or ground could also be mounted.
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:
An apparatus for grinding or trueing the surfaces of rollers or the like consisting
in the combination of an emery or other suitable grinding wheel and means for
causing the said wheel to receive both a rotatory and a traversing motion over the
roller or surface to be ground or trued which apparatus can be provided with
means for carrying the rollers or surfaces to be ground or trued or can be fixed on
the machine in which the said rollers or surfaces are used so as to render their
removal from their position unnecessary, substantially as hereinbefore described
and illustrated by the accompanying Drawings.
Dated this Fourth day of September 1884.
THO. WILLIAM BASSETT MUMFORD,
ROBERT MOODIE.
