PROVISIONAL SPECIFICATION.
Improvements in Machines for Planing or Cutting Stone and Metal,
or for like Operations.
I BENJAMIN JOHNSON of Mill Lane Works, Bramley near Leeds in the
County of York, Engineer, do hereby declare the nature of this invention to be
as follows, that is to say :-
In the production of mechanism for planing or cutting stone it is usual to make
same so that the piece of stone being acted upon is fed or moved to or towards the
cutter or tool while this latter remains stationary during its cutting operations,
however in accordance with my invention I arrange and construct the several parts
forming my improved mechanism in such a manner that the tool is moved to
perform its functions while the article or piece of stone under treatment is fixed or
stationary, thus I am enabled to produce a machine that by its lightness is rendered.
easy to move from place to place as occasion may require or that may even be
mounted on wheels for this purpose.
To carry my invention into effect I mount the box, which carries the cutting
tool upon bearings carried by a sliding arm on which they (said bearings) are
arranged to oscillate or slightly revolve as and for the purpose hereinafter
described.
The sliding arm is supported by a bed plate upon which it is caused to slide or
reciprocate by any suitable crank or other mechanism and this bed-plate is
swivelled upon a saddle made to slide upon an elongated bed by means of a screw
to which motion is communicated through any suitable gearing or other parts from
any motor.
From the foregoing it will be seen that motion may be communicated to the tool
so that it may be moved in two directions, one lengthwise the primary bed the
other at an angle to or laterally from this, thus by arranging a table in an
appropriate position relatively with the tool, as by making same extend the length
of the primary bed and about parallel with it, the piece of stone to be worked may
be placed upon this bed and the tool made to pass from end to end over it, on
which by suitable operating pieces being arranged to cause the tool box to oscillate
or tilt on its bearings to carry the tool used on such advancing movement out of
position and bring another which may be a finishing tool into operating position
the return motion of the tool carriage will bring this latter into effect so that when
it reaches the end of the piece of stone from which it started the position of it that
it had passed over would be finished, and the tilting mechanism would again be
brought into use to move the tool box to bring its advancing tool or punch into
use, while by the mechanism for imparting lateral motion to the tool being also on
such completion of the receding movement put into operation, the said tool is
moved laterally in order that at its next advancing movement it will travel over
another part of the piece of stone. These operations being repeated until all the
surface of the stone is treated as may be desired.
During the foregoing operations it will be seen that the lateral motion of the
tool is only intermittently imparted to it and that at such times as it completes its
longitudinal movements, however on the treatment of the surface of the piece of
stone as above described having been completed, the several motor parts may be
adjusted so that the tool may have its lateral motion made reciprocatory while its

page_text: longitudinal motion is only intermittently performed at the time when it has
reached the extent of its lateral path of motion either in one or both directions,.
this interchanging of the movements being required to enable the operation known
as "bosting" to be performed, and the swivelling of the bearings carrying the
tool's sliding arm upon the saddle is to enable same to be adjusted so that its
sliding arm may be made to travel at any desired angle to the longitudinal path in
which the tool travels. The coupling rods from the sliding arm to the crank
or other motor mechanism, have appropriately formed joints to allow such
movements.
The table upon which the piece of stone is fixed, is carried in bearings upon
which it may be oscillated or tilted and held by suitable worm and wheel or other
mechanism, in this manner allowing the operative to bring said piece of stone into
any desired position for the tool to act upon it.
All the mechanism above described is arranged to be mounted on bearings
carried by suitably formed axles upon which wheels are mounted so that the whole
may readily be moved as desired.
It is obvious that the machine constructed as above described may be used for
any purposes, as the planing or cutting and shaping of metal articles, for which
its peculiar features may adapt it, other than the working or treating of stone.

Improvements in Machines for Planing or Cutting Stone and Metal,
or for like Operations.
I, BENJAMIN JOHNSON of Mill Lane Works, Bramley near Leeds in the
County of York, Engineer, 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, that is to say :-
In the production of mechanism for planing or cutting stone it is usual to make
same so that the piece of stone being acted upon is fed or moved to or towards the
cutter or tool while this latter remains stationary during its cutting operations,
however in accordance with my invention I arrange and construct the several parts
forming my improved mechanism in such a manner that the tool is moved to
perform its functions while the article or piece of stone under treatment is fixed or
stationary, thus I am enabled to produce a machine that by its lightness is rendered
easy to move from place to place as occasion may require or that may even be
mounted on wheels for this purpose.
In the accompanying sheets of drawings which are illustrative of my invention;―
Fig. 1 is front elevation of a machine made in accordance with my invention.
Fig. 2 is a back elevation of the same machine.
Fig. 3 is a view of said machine as seen from above.
Fig. 4 is an end elevation as seen in the direction indicated by arrow a.
To carry my invention into effect I mount the box b, which carries the cutting
tool c (which in this case is shown as of the chisel shape, but which might be of
the well known circular or disc form) upon bearings d carried by a sliding arm e on
which they (said bearings d) are arranged to oscillate or slightly revolve as and
for the purpose hereinafter described.
:
The sliding-arm e is supported by a bed plate fupon which it is caused to slide
or reciprocate by means of the cranky' fixed upon the wheel f* operated by the
wheel f³ which is mounted to slide upon a feather or key way on the shaft f+, this

page_text: latter being rotated from the main shaft f of the machine by means of the
pulleys ff and belts 8 gearing wheels f, f10 shaft f15 and bevel wheels ƒ ƒ",
the said crank f¹ being coupled through the medium of the lever f" and suitably
jointed connecting rod f" to said sliding arm e. The bed-plate f is swivelled upon
a saddle g made to slide upon an elongated bed by means of a screw A coupled
when desired to the shaft by the bevel wheels ³ ³ or for other purposes this
screw h¹ may be intermittently operated by the shaft f* through the medium of the.
wheels hh, which latter has a cam formed at the back of it (see broken lines-
Fig. 4) to reciprocate the lever hº, the rod ', lever and ratch h³, wheel hº and
wheel 10
From the foregoing it will be seen that motion may be communicated to the-
tool c so that it may be moved in two directions, one lengthwise the bed the other
at an angle thereto or lengthwise the bed-plate f, thus by arranging a table k io an
appropriate position relatively with the tool c, as by making same extend the
length of the bed h and about parallel with it, the piece of stone m to be worked
may be placed upon this table and the tool c made to pass from end to end over
it, on reaching each of which by the arm c¹ coming in contact with the pieces c³ c
on the rod c, the said tool c is tilted on its bearings so that it is thus brought into
position to perforin its cutting operations in the opposite direction. Or in place of
this same tool c being thus brought into the two positions for cutting it will readily
be understood that another tool mounted on the same box or support may be.:
brought into use when the former is put out of use or vice versa.
с
As this tool c is thus being operated on reaching the extent of its path of motion.
the bed-plate will have also operated the belt fork n through the medium of the
rod n¹ lever n² and rod n³ so that the motion of the other parts will be reversed as
desired.
During the foregoing operations it will be seen that the lateral motion of the
tool c is only intermittently imparted to it and that at such times as it completes
its longitudinal movements, however on the treatment of the surface of the piece
of stone m as above described having been completed, the several motor parts may
be adjusted (as by the wheels f" being in gear with each other while the
wheel ³ is out of gear with its clutch, at which time the screw is intermittently
rotated by the parts to 10 above described) so that the tool c may have its.
lateral motion made reciprocatory while its intermittent longitudinal motion is
performed at the time when it has reached the extent of its lateral path of motion,.
either in one or both directions, this interchanging of the movements being required
to enable the operation known as bosting or that known as tooling to be.
performed, and the swivelling of the bearings f upon the saddle is to enable
same to be adjusted so that said bosting and tooling operations may be performed
or carried out to leave the markings of the tool c on the stone m at any desired
angle to the longitudinal path in which the tool c travels. The coupling rod f14.
being provided with appropriate joints to allow freedom for such movements.

The bearings p p which are mounted upon the table k for carrying the piece of
stone m are arranged so that they may be tilted by the worm q and wheel g¹ as the.
operative may desire to bring said piece of stone m into position for the tool c to
act upon it as will be understood, while by the supporting racks rr operated by
the hand wheels through the wheels s¹s and worms and wheels & t¹ t² t³, said.
table k may be raised or lowered as is from time to time found necessary. The
further supports u being brought into use when this table k has been finally
adjusted in position.
All the mechanism above described is arranged to be supported by bearings v
carried by suitably formed axles to w¹ upon which wheels x are mounted so that
the whole may readily be moved as desired.
It is obvious that the machine constructed as above described may be used for
any purposes, as the planing or cutting and shaping of metal articles, for which its
peculiar features may adapt it, other than the working or treating of stone.
