Sealed the 19th March 1867, and dated the 19th October 1866.
PROVISIONAL SPECIFICATION left by the said Edward Wills Uren
the Office of the Commissioners of Patents, with his Petition, on "the
19th October 1866.
I, EDWARD WILLS UREN, of Arnold's Point, Embankment Road, Laira,
Plymouth, in the County of Devon, Engineer and. Contractor, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE ARRANGE-
MENTS OF MACHINERY FOR DRESSING GRANITE AND ALL OTHER KIND OF STONE,"
to be as follows:-
- Drawings A & B.-An upright pillar a of iron or.of some other material
is firmly secured to a block of stone, iron, timber, or otherwise. To
this pillar there are two plates of iron.c with a round aperture in the
middle of each, plate for the pillar.to pass through; they are placed at a
sufficient distance from each other to admit of. the ends of beams of timber d
or other material to be placed between them of a thickness as required,
the beams nearly, abutting against the pillar and firmly secured with bolts,
the beams-laying horizontally outwards and of a length as required, and
to revolve round the pillar a when propelled. There is a plate of iron e, or
other mettle of a similar diameter as plates c above firmly secured to the

page_text: pillar, and at a small distance below the plate under the beams; this plate
having friction rollers f attached thereto for the plate c above to bear on
and to revolve round the pillar when the motive power is applied. The
outer end of those beams are supported to the top of the pillar a by
guys h extending from a plate or cappin fixed on the top of the pillar a with
a socket in the plate to fit on the top of the pillar so as to revolve as
required; the guys h will go through small apertures in the cappin, whose ends
are fitted with screws and nuts and are firmly screwed up to the cappin to
tighten the guys as required; at the outer ends of the beams, and on each
side of them, the other or lower ends of the guys h are secured to the beams
to a part about one-third of the length of beams inwards from the outer ends;
these guys will keep the beams suspended horizontally at or near the outer
edge of those beams, and on each side of the beams there are brackets L
secured to the beams to increase its width, and through the middle of the
beams and brackets there is an aperture for an iron axle or shaft m to pass
through; those iron axles or shafts are passed through the apertures near the
ends of beams and placed perpendicular to the beams, and will revolve in
those apertures; those upright shafts or axles are suspended to levers n fixed
above them, the shaft having a nobo at the top, the shaft passing through an
aperture at the end of levers the shafts become suspended to the levers by
means of being caught with the nobo at the top; those upright shafts are
provided with a nut and screw p under the nob at the top for the same
purpose for adjusting the stones g fastened to a plater at the bottom of the
shafts. There are plates of iron s with a circular aperture in the middle for
those upright shafts to pass through; and are fixed secure to the beams
placed there for the nuts p on the shafts to. work on for adjusting the
axles or shafts of the small wheels. Under these plates, and above the
beams, and firmly secured to. the axles or shafts m there are wheels t fixed
with grooves in their periphery; the wheels are risen or indented as the
shape of the links of the chain u to catch hold of which is to be used for
propelling when a chain shall be used. The periphery of the wheels are
to be differently formed should there be a belt or rope used for propelling
in the place of a chain. The levers n that support the uprights shafts or
axles have their bearings about one-third of its distance between the
shaft and the pillar; those bearings are securely fastened to the beams. At
the inner ends of the levers there are apertures for upright bars w of
iron fitted with a screw and nut to pass through, they are secured with
a swivel bolt in a socket. a .at the bottom.; the socket is secured to the
top plate which secures the inner ends of the beams; the top of those

page_text: bars which passes though the inner ends of the adjusting levers are pro-
vided with a screw and nut'y on the top; the intention of those screws
and nuts are to adjust the upright shafts or axles m of small wheels
with the wheel and stone suspended at the outer end of the levers, so as
to lessen the weight of the stone q on the rubbing bed . At the bottom
of those upright shafts or axles at the outer ends of the beams there is secured
to them a plate of iron r or other metal which revolves with the shafts, to
those plates there are firmly secured frames of iron a, a, of a form suited for
the purpose so as to overlap the stones a that are to be dressed and rubbed,
fitted with screws and nuts near the bottom and attached to the frame, the
stones being secured to the frame a, a, by the means of those screws and nuts.
On the top of beams, and all round the outer ends of beams, and at equal
distance from the centre there is a plate of iron b, b, firmly secured to the
outer ends of the beams, some portion of this plate; between each beam there
is a segment c, c, of a wheel, cast to the same, with a groove on the periphery
of this segment with the reverse shape of the links of the chain risen and
indented on the periphery of the segments for the links of the chain to tako
hold of when propelled by the chain, similar to the small wheels. The small
wheels are constructed to revolve at a greater number of revolutions than the
large wheel b, b, according to their respective diameters in proportion to their
diameters to the large wheel b, b; at the same time the large wheel b, b, makes
its revolutions the small wheels t will make their inward revolutions, it being
an extra 'number in addition to what is obtained by the revolutions of the
large wheel b, b, according to the size of their diameters to large wheels,
thereby obtaining extra dressing by rubbing in addition to the stones rubbed
by large wheel only. There are plates of iron d, d, under the beams and
secured to the beams for the axles or shafts of small wheels t to pass through.
The chain u, belt, rope, or other similar contrivance to be used for propelling
is placed in the groove of the segments c, c, round the periphery of the large
wheel b, b, and at the same time takes hold of a part of the periphery of the
small wheels t, falling into the grooves, and the parts of the periphery of the
small wheels that is grooved and indented for the chain to take hold of is then
conveyed to a part where two wheels c, e, are placed between them, and from
the two wheels to the motive power to propel the machine by the propelling
power forming an endless chain, belt, rope, or a similar contrivance for
propelling. At a convenient distance from the rubbing machine there is an
erection of stone f, f, iron, or wood; on the top is placed a plate of iron h, h,
fixed with a groove in it; with this plate is fixed two wheels e, e, with their
periphery grooved as small wheels of machine placed horizontally, the axles,

page_text: working in sockets, the bearings working in a groove which is in the plate,
which will slide forwards and backwards as might be required when pressed
with the screws i, i, which is placed at the ends for that purpose; those wheels
are to keep the chain properly tightened up. There is a bed of stone z under
the outer part of the machine for the stones suspended to the shafts or axles
of. small wheels and plate to be rubbed on by the friction caused by the revo-
lutions, there being water and sand used for the purpose of dressing. the stone
to an even surface.
Drawings C & D.-Other machines are attached, propelled by motive
power, which are provided with tools attached to them for clefting stones in
two; tools for spalling stones; tools for pitching the arises off stones for the
chisel to follow; tools for scaffling the faces, beds, or joints with picks, tools
for pick dressing the faces, beds, and joints; tools for tooth axing faces, beds,
or joints; tools for fine axing. faces, beds, and joints; tools for chisels, for
chisel drafts to arrises, drafts on the faces, beds, and joints of the stones; all the
tools will be attached to the machines so as to enable them to perform either
straight, circular, bevelled mouldings or sinkages on stone.
Those machines are worked or propelled on the principle of the steam
hammer or by a similar contrivance of a novel construction; those machines
are fixed on an erection of stone, wood, iron, or otherwise erected above the
trucks which bears the stone to be dressed, the trucks being placed on a
railway which passes under the engines which have the required tools attached
to them for performing the different kinds of dressing work required to be
performed on that stone, or otherwise the engine taken to the stones..
Drawing C, Fig. 1. The first engine is supplied with a clefter a, the bottom
is formed with what is called a chisel, but which is a large hammer of iron
steeled at one end or composed of all steel, they are so constructed so as to
be securely fastened to the bottom of the cylinder 6, or otherwise to that portion
or bottom of the steam hammer b that when the hammer descends it will fall
level on a level surface of the stone c which is under the machine, bearing on
a truck f, for that purpose the clefter will be forcibly driven down on the stone
with a few blows cleft the stone as required.
Fig. 2. The second engine is the pick q, scrappler, and rough pick dressing
machine e, the tools called picks q have each end pointed with an aperture in
the middle, they are firmly secured to the bottom of the cylinder b, or otherwise
to that portion or bottom of the steam hammer that when the picks forcibly
descend they come in contact with the stone c to be scrappled off of its rough
form which is done by repeated blows, the stone forming a uniform rough
scrappled and true surface, the stones bearing on the trucks that are tilted to

page_text: |a certain angle-of degrees as shall be required; the picks are made of steel or
iron and steel together.
⚫ Fig. 3. The third engine is the fine pick dressing machine'; the tools used
are similar to those used for scrappling, the picks h will be used of a larger
number together than is used for scrappling stone, the picks are used in rows h
or otherwise secured to the bottom of the steam hammer or similar to the
picks for scappling, but those will fall perpendicular on the stone c which lays
level on the bed of the truck.
Fig. 4. The fourth engine is the tooth axer i; those tools have each two
cutting parts opposite to each other drawn out thin wedgeways; those cutting
parts have notches cut out forming as many points made sharp, they are
composed of steel, or iron and steel, with an aperture in the middle, a number
of them are firmly secured in rows to the bottom of the steam hammer 6 or
otherwise, similar to the manner in which the picks are secured, and fall
perpendicular on a level surface of the stone c to be tooth axed, which lays
on the bed of the truck f, tooth axing is the method for bringing the surface
of the stone finer than can be done with picks.
...Drawings D, Fig. 5. The fifth engine has the spalling hammer k attached
to it; this tool has one end slightly levelled at the bottom, and made of steel
or steel and iron, and is firmly secured to the bottom of the steam hammer 6
or otherwise, similar to the manner in which the picks are 'secured to the
cylinder, and with force descend perpendicular on that part of the-stone that
is to be spalled off.
.
Fig. 6. The sixth engine is for fine axing; it is composed of a quantity of
thin plates of steel m' of convenient lengths and widths laid flatways against
each other; with thin pieces of wood placed between them; they are then placed
between two plates n of iron, those plates of iron are firmly secured to the
bottom of the cylinder of the steam hammer 6 or otherwise secured, with a
thin piece of wood o on each side between the iron plate, and the part where
they are secured to the bottom of the cylinder b, as before stated; the object
of the thin wood is to cause the plates to be more firmly secured.
Fig. 7. The seventh engine is for pitching the joints straight; the pitching
tool n is made of-steel or steel and iron, it is of the shape of the spalling
hammer, it is used solely for pitching off the waste from the edges of the
stones so as to form the arrises a straight and sharp for the chisel to follow;
this tool is worked by a contrivance m so as to allow the tool to rest at will on
ór against the edge of the stone c to be acted on by the hammer b that strikes
those tools, and are constructed so as to fall against each other at any angle
of degree at will as might be required with force, pitching off the part straight-

page_text: to cause the 'arris a to be kept up sharp for the chisel to act on to form a:
sharp straight and complete arris to the stone c.
.
Fig. 8. The eighth engine is for the chisel a; this tool at one end is in the
form of a sharp wedge, it is made of steel or part steel and iron, it is attached
to the engine in a manner to the other tools,. the chisel a will lay at 6
will against the stone c, and can be placed at any degree of inclination, and
will move regularly, and at each time of moving it will be struck on the top
or end n with a hammer in which is attached to and worked by the same
engine 6; by such motion it makes a straight draft and arris a as required,
the stone being on trucks and by an attachment of machinery from the trucks 1
to the motive power the trucks are drawn gradually forward to 'the stone
against the chisel a until the chisel draft is driven its full length, or the engine
'constructed to be drawn to the stone; the machine is similar to the other.
engines before stated.
Fig. 9. There are other similar engines a to the steam hammer to be used 1
for all those tools m, to be secured to and worked by lèvers c bearing in the
middle; into the one end of the lever is attached the motive power, at the other
end c is attached the upright rod n, working up and down in a socket ȧ of the
projecting frame; below the tools m are secured to a hammer which is secured
to this last rod, which slides up and down perpendicularly by means of one rod a
o secured to each side of hammer b and one on each side of end of lever c;
this lever answers a similar purpose as the steam hammer, and rises and falls
perpendicularly.
Drawing C, Figs. 1, 2, 3, 4. The trucks a attached to those engines are.
constructed with beds a placed on two axles b; the axles to receive four wheels
c with flanges; these wheels to run on rails and are constructed in the following
manner. On the axles are secured a cog wheel d worked by a pinion wheel e
on an attachment of gear to the motion power with the pinion wheel, which
will be on a small axle p, at the end is a handle for propelling the trucks as
required, the axles are secured to the bed a of the truck to adjust the stone in
that direction under the trucks for dressing the stone that is on them as might
be required. On the bed of the trucks a there is placed a plate of iron i with
a conical spire k raised in the centre for a pivot for another plate m which is
on the top to swivel on, and on the outer edge friction rollers n work round,
also there are cogs placed a small distance in from the edge of the plate for
the pinion wheel that is fixed above to work in for swiveling the next bed of
the truck round. At a small distance above the bottom plate, and attached
under the next frame, there is another plate of iron with friction rollers n
attached, these rollers bearing on the plate below. There is also a pinion

page_text: wheel o.on an axle p with handles attached to this plate which works in the
cogs of the plate below; this pinion wheel gives motion to and swivels the
second bed g of the truck and all above quite round, or as far as should be
required. On the second bed q of the truck, and at each end of the truck,
there are placed two plates of iron r, one smooth for wheels with flanges to
run on, the other with cogs for a pinion wheel to work in for moving the top
bed with the stone on it either inwards or outwards as required to be done.
At the bottom of the top bed f of the truck are placed two plates o of iron, to
which are secured wheels s to run on the rails placed below, also there are
placed a pinion wheel and axle with handles, the pinion working in the
cogs below for, moving the top carriage inwards or outwards as they are
required.

or stonecutters tool b, known by the name of a pick for scappling or .beating
the rough waste from the stone, and rough pick dressing the stone secured to.
the bottom of the cylinder d, or to a piston rod of a steam hammer, or other-
wise secured to similar engines to the steam hammer. Figure 3, this steam
hammer or engine e is supplied with masons' or stonecutters' tools h, known
by the name of picks for fine dressing; the stones secured to the bottom of the,
cylinder d, or to a piston rod of a steam hammer, or otherwise secured to
similar engines as the steam hammer. Figure 4, this steam hammer or engine.e.
is supplied with masons' or stonecutters' tools, called. tooth. axing tools i,
which have two cutting parts, one at each end, and have notches cut out
forming sharp points for dressing the stones secured to the bottom of the
cylinder b, or to a piston of a steam hammer, or otherwise secured to
similar engines to the steam hammer. Figure 5, this steam hammer or.engine e
is supplied with a masons' or stonecutters' tool r, called a spalling hammer, used
for spalling stones securely fastened to the bottom of the cylinder b, or to a
piston rod of a steam hammer, or otherwise securely fastened to similar engines
to the steam hammer. Figure 6, this steam hammer or engine e is supplied
with masons' or stonecutters' tools m, called a fine axing tool; it is formed of a
quantity of thin plates of steel of convenient length and breadth laid flatways
against each other, they are placed between two plates n of iron. Those plates
of iron n have two thin pieces of wood-o between them, and the plates of steel
securely fastened to the bottom of the cylinder b, or to a piston rod of a steam
hammer, or otherwise securely fastened to a similar engine, to the steam.
bammer. Figure 7; this steam hammer or engine e is supplied with a mason's"
or stonecutter's tool n, called a pitching tool; for pitching off the arrises of the
stone c, securely fastened to the bottom of the cylinder b, or to a piston rod of
a steam hammer, or otherwise securely fastened to a similar .engine to the
steam hammer, and made to lay on the stone, the arrises pitebed off by a blow,
from the bottom of the hammer band guided by the rods and socket m..
Figure 8, this steam hammer or engine e is supplied with a mason's or stone-
cutter's tools, called hammer m and chisel a, for driving the chisel drafts to:
form the arrises to the stone c true and straight, securely fastened to the
bottom of the cylinder b, or to a piston rod of a steam hammer, or otherwise
securely fastened to a similar engine to the steam hammer. The hammer m
strikes the head of the chisel a. at each stroke of the steam hammer with
successive blows. The stones c. being on trucks and by an attachment of a
belt from the trucks to the self-acting screws and to the motive power, the-
trucks are drawn gradually forward with the stone against the chisel a until

page_text: the chisel draft is driven to the full length of the stone as shall be required,
and then the trucks return again; or the engine can be placed on wheels or
trucks and drawn to the stone with self-acting machinery as are applied to all
the trucks or engines. Figure 9, this engine has the application of masons!
or stonecutters' tools. m attached to it, in a similar manner to the steam
hammer, and worked by levers c bearing in the middle, at the end of the lever c
and at the end d there is to be attached the top part of a piston rod of a steam
hammer, which works up through the top part of the cylinder of a steam
hammer and have the motive power applied upwards. At the other end of
the lever c there is an upright rod n working up and down in a socket a of
the projecting frame H at the bottom of this rod. The masons' or stonecutters'
tools im are securely fastened to a hammer 6 or to the bottom of the rod of
hammer b.
•
Drawing A, Figures 10 and 11, shows the masons' or stonecutters' tools a
attached to the piston rods d of two different steam hammers. Figure 10,
fixed on a truck H, which is on a railway; Figure 11 fixed on a bed of stone c;
the piston rods & pass through the bottom and top of the cylinder 6; the reason
for passing the piston rod d through each end of the cylinder 6 is to keep the
tools a in its proper position when the tool is struck on the stone, which
otherwise would not be the case if the piston rod d passed through one end of
the cylinder b only.
Drawing B, Figures 1, 2, 3, is the trucks a used to convey the stones.to
the steam hammer or to similar engines; they are constructed with a bed a
placed on two axles b, the axles to receive four wheels c with flanges. Those.
wheels run on rails r, and are constructed in the following manner :-On the

the trucks as required; the axles are secured to the bed a of the trucks to
adjust the stone as required, that is, on the trucks for dressing the stones. On
the bed a of the trucks is placed a plate of iron i with a conical spire k raised
in the centre of the plate i for a pivot for a second plate m which is on the
top to bear and swivel on, and on the outer edge for friction rollers n to
revolve on, also there are cogs cast to the plate for the pinion wheel o that is
fixed on an axle above to work in for swivelling the next bed of the truck
round. At a small distance above the bottom plate i and secured under the
next frame 9, 9, there is a plate of iron m with friction rollers n attached the
rollers bearing on the plate below. There is a pinion wheel o on an axle with
handles attached to work in the cogs of the plate below; this pinion wheel o

page_text: gives motion to and swivels the second bed q. q, of the trucks and all of them
round as far as required. On the second bed q, q, of the trucks, and at each end,
there are placed two plates of iron r, o, one smooth for wheels with flanges to run
on, the other with cogs for a pinion wheel to work in for moving the top bed f
with the stone c on it inward or outward as required to be done to keep the
stone under the tools; at the bottom of the top bed f of the trucks are secured
two plates of iron, to which are secured wheels to run on the rails placed
under them, also there is placed a pinion wheel t and an axle with handles,
the pinion wheel working in cogs r, o, below for moving the top bed of the
trucks inwards or outwards as they are required. On the top bed of the
trucks a used for cleaving the stone, there is a half round bar a, a, of iron
placed in the middle of the top bed of the trucks for the stones to bear on for
cleaving, Figure 1, Drawing B. Figure 2, the truck used for scappling stone
or rough pick dressing stones have a fourth bed b, b, placed on an elevated
frame bearing on an axle c, c, with a segment e, e, of iron with cogs, the
segment e, e, is secured to the top bed b, b, to a plate of iron, d, d; secured
to the bottom of the top bed b, b,there is an axle and a pinion wheel c, c, a,
with handles, the pinion wheel to work in the cogs of the segment f, and is
for the purpose to adjust and regulate the top bed b, b, to the degree of inclina-
tion as required, also to tilt the bed b, b, of the truck with the stone over
from one side to the other when required. To each of the trucks or near
the trucks there is attached a self-acting machine for propelling the
trucks with the stones on them under the tools attached to the steam
hammers or the steam hammers that are on the trucks taken to the stones.
Drawing A, Figure 10, which is propelled by an attachment of a belt to
the steam hammer, or otherwise attached to the motive power.
And having now described the nature of my said Invention of improvements
in the arrangements of machinery for dressing granite and all other kinds of
stone, and the best means with which I am acquainted for carrying the same
into effect, I would observe that I do not mean or intend to confine myself
rigidly to the precise arrangement or construction of parts herein shewn and
described, as they may perhaps be varied in some particulars without departing
from tho nature and object of my improvements; in conclusion I claim as the
Invention to be secured by the herein-before in part recited Letters Patent,―
First, improvements in the arrangements of machinery for dressing granite
and all other kinds of stone with the stones suspended to wheels and worked
by a rotary and excentric motion, the description and particulars of which
are fully described in the foregoing Specification and Drawings A and B.
Second, I also claim the application of all kinds of masons' or stonecutters'

page_text: tools to be attached to all kinds of steam hammers or attached to all machines
worked on the principle of the steam hammers, and to be used for dressing
'granite and all other kinds of stone, as is set forth and described in the
"Specification and Drawings A and B.
Third, I also claim the arrangements of all those machines for dressing
granite and all other kinds of stone, as set forth and described in the
Specification and Drawings A and B.
Fourth, I also claim the particular arrangements of all the machinery
'specified, and of the trucks and their construction with the self-acting motive
'power for propelling them used for dressing granite and all other kinds of
stone, as set forth and described in the Specification and. Drawings A and B.
In witness whereof, I, the said Edward Wills Uren, have hereunto set.my
hand and seal, this Fifteenth day of April, in the year of our Lord One
thousand eight hundred and sixty-seven.
