Year: 1881

page_text: LETTERS PATENT to Andrew Lamberton, of Coatbridge, in the County of
Lanark, North Britain, Engineer, for an Invention of "IMPROVEMENTS IN
ROAD MAKING ENGINES, WHICH ENGINES ARE ALSO APPLICABLE TO BE USED
AS TRACTION ENGINES."
PROVISIONAL SPECIFICATION left by the said Andrew Lamberton at the
Office of the Commissioners of Patents on the 2nd August 1881.
ANDREW LAMBERTON, of Coatbridge, in the County of Lanark, North Britain,
Engineer. "IMPROVEMENTS IN ROAD MAKING ENGINES, WHICH ENGINES ARE
ALSO APPLICABLE TO BE USED AS TRACTION ENGINES."
This Invention relates to improvements in engines for making roads, and it
consists in combining a stone breaking apparatus and a road roller in one and the same
machine, whereby as the machine travels over the ground the stones or "metal" used
in making the road are broken, crushed, or cubed to the proper size and distributed,
the machine thereby leaving behind it a track of newly laid stone or "metal,"
which track is rolled in on the return of the machine, the three processes of
breaking, crushing, or cubing, of laying or distributing, and of rolling, being thus
carried on simultaneously in lieu of the more expensive process of first breaking
the stones or "metal" by hand or in a separate machine, and thereafter conveying
them to the situation at which the road is to be made, as has hitherto been
the case.
The apparatus consists of a framing, whereon is mounted or carried a horizontal,
vertical, or diagonal steam engine, or a pair of such engines, and a vertical or
horizontal steam boiler, the framing being carried on heavy road rollers, which are
caused to propel the machine by connecting their, or one of their shafts or
axles to the crank shaft of the engine by any suitable gearing, as is well understood
and practised.
In the framing the stone breaking apparatus is also carried, and the movable
breaking or cubing jaw or roller of the said apparatus is also connected to and
receives it motion from the said engine, the stone or "metal" as it is broken or cubed

page_text: falling into a distributor by which it is laid evenly in a track on the surface of the
ground behind the machine, which, after travelling any desired distance in one
direction is reversed, and the rollers moved in the opposite direction over the newly
laid track, the great weight of the machine causing the rollers to sink or crush the
stone or "metal" into the road.
On the framing a hopper, box, or receptacle to contain the unbroken stone or
"metal" is or may also be situated, or the said stone or metal may be carried in a
tender or truck coupled to the combined machine.
The stone breaking apparatus is or may be connected to the engine by a clutch
or equivalent mechanism, and by throwing the said clutch or its equivalent out of
gear the stone breaker is rendered stationary, and the combined engine may then
be used as a traction engine for all sorts of haulage work for which such engines
are applicable.

the said Andrew Lamberton in the Great Seal Patent Office on the 1st
February 1882.
ANDREW LAMBERTON, of Coatbridge, in the County of Lanark, North Britain;
Engineer. "IMPROVEMENTS IN ROAD MAKING ENGINES, WHICH ENGINES ARE
ALSO APPLICABLE TO BE USED AS TRACTION ENGINES."
My said Invention relates to improvements in engines for making roads, and it
consists in combining a stone breaking apparatus and a road.roller in one and the
same machine.
And in order that my said Invention may be properly understood, I now proceed
more particularly to describe the system, mode, or manner in or under which the
same is or may be used or carried out in practice, reference being had to the
accompanying Sheet of Drawings and to the letters and figures marked thereon,
that is to say:-
On the Sheet of Drawings hereunto appended Figure 1 is a side, elevation, and
Figure 2 a plan of the stone breaking and road rolling apparatus combined in
accordance with my said Invention. The apparatus consists of a framing A,
whereon is mounted a horizontal steam engine B, or a pair of such engines, and a
vertical steam boiler C, the framing being carried on heavy road rollers D, E, which
may be caused to propel the machine by gearing the shaft or axle F, on which the
rollers D are keyed to the crank shaft of the engine by the train of spur wheels H,
Figures 1 and 2, or as shown under another arrangement at Figure 3 by the bevil
gearing I, worm J, and worm wheel K, or by any other suitable gearing, as is well
understood and practised.
In the framing A the stone breaking apparatus M is also carried, and the
movable breaking or cubing jaw or jaws thereof is or are connected to the crank
shaft S' of the engine B by the connecting rod S, which is or may be thrown into
and out of gear with the said shaft by a clutch or other equivalent mechanism, or
by entirely disconnecting the rod S from the crank. The stone or metal as it is
broken or cubed falls in a heap on to the road, from which heap, after the machine
has been moved a distance forward, it is subsequently spread level by hand. Under
this mode of working when the stone breaker is in operation the road rollers D
are thrown out of gear with the engine, and the machine is prevented from
travelling by sliding the spur wheel H in the train of wheels H out of gear by
means of a clutch or equivalent apparatus.
Under another method of working, the stone or metal may pass from the breaking
or cubing jaws into a distributor, by which it is evenly laid in a track on the
surface of the road behind the machine as it travels along.
The engine B, after the machine has travelled any desired distance in one
direction is reversed, so as to cause the machine to travel in the opposite direction
over the stone or metal spread either by hand or by the distributor as before set
forth, and the said stone or metal is then by the rollers D, E, crushed or sunk into
the road.
The machine in travelling is steered or guided by mounting the front roller E in
a bogie or swivel, and connecting the axle of the roller to a shaft O by chains P,
the chains being wound round the said shaft in opposite directions. The shaft is
rotated by the hand wheel, spindle worm, and worm wheel R, or the gearing for
steering, as well as that for propelling the machine, may be of any other well
known type, it being understood that such gearing constitutes no part of my said
Invention, which essentially consists in combining a stone breaking apparatus and
a steam road roller in one and the same machine, and in thereby rendering the
stone breaking apparatus self propelling.

page_text: When not employed in road making the engine may be used as a traction engine
in all sorts of haulage work for which such engines are applicable, the stone
breaking apparatus being first thrown out of gear.
Having now described and particularly ascertained the nature of my said
Invention, and the system, mode, or manner in or under which the same is or may
be used or carried out in practice, I would observe in conclusion that what. I
consider to be novel and original, and therefore claim as the Invention secured to
me by the hereinbefore in part recited Letters Patent is,-
Combining in one machine a stone breaking and a steam road rolling apparatus,
and whereby the said stone breaking apparatus is rendered self motive, substantially
as hereinbefore described and shown on the appended Drawings.
In witness whereof, I, the said Andrew Lamberton, have hereunto set my hand
and seal, this Twenty eighth day of January, in the year of our Lord One
thousand eight hundred and eighty two..
