Year: 1884

page_text: I WILLIAM ROBERT LAKE of the firm of Haseltine Lake & Co Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of said Invention for "IMPROVEMENTS IN MACHINES FOR CUTTING QUARRYING
AND SHAPING STONE" 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 apparatus for cutting, quarrying, and shaping stone
and consists partly in providing means whereby the cutter is operated and the
supporting carriage thereof simultaneously advanced with the motive power
attached.
It also partly consists in providing the carriage with means for preventing the
same from slipping on the tracks.
It also partly consists in providing the cutter with means for smoothing the cut
stone.
In the accompanying Drawing,
Figure 1 is a side elevation of a rotary quarrier and stone-shaper constructed
according to this Invention.
Figure 2 is a top view of a portion thereof.
Figure 3 is a vertical section on the line x, x Figure 1.
Figure 4 is a view partly in section of a portion detached.
Figure 5 is a side elevation of a portion of the cutter drawn to an enlarged scale.
Figure 6 is an edge view thereof partly in section on the line y y Figure 5.
Similar letters of reference indicate corresponding parts in the several Figures.
A indicates a frame or carriage which runs on a track placed on the stone to be
cut, and on which is supported a steam-engine B, the power whereof is transmitted
by the wheel B₁ to a band wheel C, whose shaft C is mounted on the said
carriage A, and carries a worm D, the steam generator being also supported on the

page_text: carriage. In lieu of a steam engine I may employ any other motor, the same
however being sustained on the carriage A, and furthermore gear the wheel C
directly with one of the wheels of the engine.
E indicates a worm wheel which engages with the worm D and is secured to a
longitudinally extending shaft E¹, the bearings whereof are on the carriage A.
The said shaft carries a series of radially arranged spurs or studs F and is geared
with a shaft E" which carries a series of radially arranged spurs or studs F¹, it
being noticed that the studs F, F', are located on opposite sides of a rotary
cutter G, and engage with openings a therein, whereby the rotation of the
shafts E, E, operates the said cutter, the direction of rotation of the latter being
indicated by the arrow, Figure 1.
A
The cutter has its shaft A¹ mounted on the carriage A, and to the said shaft is
keyed, or otherwise secured, a bevel pinion b with which engages a pinion b¹ whose
shaft c is mounted on the carriage A and extends in the longitudinal direction
thereof, the said shaft e having also secured to it a worm which engages with a
worm wheel e, the shaft f of which is geared, as at g, with a shaft h whose ends
have secured to them the rollers or wheels H of the carriage, the shafts fh, having
bearings on the said carriage.
When the engine is set in motion, the power thereof is communicated by the
intermediate mechanism to the shafts E, E, and consequently to the cutter G,
whereby the stone beneath the carriage is expeditiously cut or channeled.
As the direction of rotation of the cutter is from below upward, the carriage is
held firmly on the top of the stone and the cuttings or chips are brought to the
surface and thereby removed. Simultaneously with the rotation of the cutter G,
motion is imparted by the shaft A¹ of the said cutter and the connected mechanism
to the rollers or wheels H of the carriage, the effect whereof is to advance the
carriage with its superimposed parts and force the cutter constantly against the
stone, so that the cutting of the same is expeditiously performed.
In the operation of the cutter and carriage, the mechanism therefor is properly
timed or adjusted, so that the feeding of the cutter is in harmony with the power
imparted to the same, and the best results are obtained without injury to the
cutter or strain on the mechanism.
The peripheries of the wheels H are formed with studs, spurs or teats k, and the
track Jon which the carriage is run is perforated or pierced at intervals to accord
with the studs kc, so that when power is imparted to the wheels, their studs enter
the perforations of the tracks whereby the wheels take firm hold of the tracks and
are thus prevented from slipping.
In the present case, the openings in the tracks are arranged in two rows and
alternating or staggered (see Figure 4,) and the studs are correspondingly
arranged, thus increasing the number of studs and ensuring the engagement of
the wheels and tracks.
The cutter G which is of the form of a disc similar to a circular saw or may be
composed of a peripheral rim secured by arms to a hub has detachable teeth or
bits G¹, and to opposite sides of the cutter between some or all of the bits are
secured plates K having serrated surfaces somewhat like rasps or files, the thickness
of the plates being slightly greater than that of the bits, whereby when the cutter
is in operation, the plates K following the action of the bits come in contact with
the sides of the cut stone and trim and smooth the same in a desirable manner,
.avoiding subsequent manipulations to accomplish such result.
If desired, the rollers or wheels H may be mounted on the shafts f, in which case
the gearing and shaft h will be dispensed with.
The portion of the carriage A which supports the engine or motor is detachably
connected as at m, with the portion which supports the cutter and its operating
mechanism, for convenience of locating, removing and transporting the device and
other purposes.
