Year: 1872

page_text: LETTERS PATENT to John Whittingham, of the Cross, Willaston,
Nantwich, in the County of Chester, Surveyor, for the Invention
of "IMPROVEMENTS IN ROAD ROLLING ENGINES WHEREBY THEY ARE MADE
SUITABLE ALSO FOR OTHER PURPOSES."
Sealed the 5th July 1872, and dated the 23rd January 1872.
PROVISIONAL SPECIFICATION left by the said John Whittingham at
the Office of the Commissioners of Patents, with his Petition, on
the 23rd January 1872.
I, JOHN WHITTINGHAM, of the Cross, Willaston, Nantwich, in the
County of Chester, Surveyor, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN ROAD ROLLING ENGINES WHEREBY THEY ARE
MADE SUITABLE ALSO FOR OTHER PURPOSES," to be as follows:-
This Invention has for its object improvements in road rolling engines
whereby they are made suitable also for other purposes, and relates to
the adaptation to an arrangement, in combination with such engines, of
machinery or apparatus for breaking or crushing stones or other hard

page_text: substances in such manner as to enable the motive power of the combined
machine to be employed either in propelling the engine for rolling roads
or such like surfaces, or in driving the machinery or apparatus for
breaking or crushing stones or other hard substances. For this purpose
I attach the machinery or apparatus for breaking or crushing stones or
other hard substances to the framing of the engine so that the stone
breaker or crusher will by its weight assist the roller in consolidating
the roads or other such like surfaces, and I support the main shaft of
the engine in bearings in a convenient situation for either giving the
necessary motion to propel the engine over the road or surface to be:
rolled, or for actuating the moving parts of the machinery or apparatus
for breaking or crushing stones or other hard substances.
In order to convey the necessary motions from the main or driving
shaft I provide it with wheels, pinions, or equivalent devices and gearing
or connections, so that when it is desired to employ the motive power in 1
propelling the engine for rolling roads or such like purposes, the neces-
sary connection between the main or driving shaft and the driving
wheel or wheels of the engine can be made or put into gear, and the
parts, straps, or gearing whereby motion is transmitted from the main
or driving shaft to the moving parts of the machinery or apparatus :
for breaking or crushing stones or other hard substances may be thrown
out of gear or disconnected, and vice versa.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Whittingham in the Great Seal Patent Office 25
on the 23rd July 1872.
TO ALL TO WHOM THESE PRESENTS 'SHALL COME, I, JOHN
WHITTINGHAM, of the Cross, Willaston, Nantwich, in the County of
Chester, Surveyor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 30
Letters Patent, bearing date the Twenty-third day of January, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Whittingham, Her special licence
that I, the said John Whittingham, my executors, administrators, and 35

page_text: assigns, or such others as I, the said John Whittingham, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN ROAD
ROLLING ENGINES WHEREBY THEY ARE MADE SUITABLE ALSO FOR OTHER PURPOSES,"
upon the condition (amongst others) that I, the said John Whittingham,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and scals, should particularly describe
and ascertain the nature of the said Invention, and in. what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Whittingham, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, and the Drawings therein referred
to :-
This Invention has for its object improvements in road rolling engines
whereby they are made suitable also for other purposes, and relates to
the adaptation to and arrangement in combination with such engines of
machinery or apparatus for breaking or crushing stones or other hard
substances, in such manner as to enable the motive power of the com-
bined machine to be employed either in propelling the engine for rolling
roads or such like surfaces, or in driving the machinery or apparatus for
breaking or crushing stones or other hard substances.
Fig. 1 of the accompanying Drawings represents in side elevation an
onginc embodying my improvements; Fig. 2 is a plan of the same;
Fig. 3 is a transverse section, taken in the line A, B, of Fig. 4, shewing
the roller with its shaft and actuating gear; Fig. 4 is a longitudinal
section taken in the line C, D, of Fig. 3.
a is the framing of the engine to which is attached the machinery or
apparatus for breaking or crushing stones or other hard substances, so
that the stone breaker or crusher will by its weight assist the roller in
consolidating the roads or other such like surfaces. The stone breaker
or crusher consists of a cast-iron box b, formed with a slot or opening b',
•

page_text: and fitted with a fixed serrated steel jaw c, some of the teeth of which
project at their upper parts beyond the other teeth to facilitate breaking
long pieces of stone or other substance, and a similar jaw d attached to
a moveable block ď³ connected to the box 6 by means of links e. The
moveable block d' and with it the jaw d are moved to and fro in a {
direction oblique to the fixed jaw c so as to produce a combined rubbing
and squeezing action by means of the lever which works on a fulcrum
pin f¹ and receives motion from the main shaft g through the medium of
the connecting rod h; this connecting rod works on an eccentric i pro-
vided with a clutch j for throwing it in and out of gear with the main ]
shaft g. The Drawing shews the eccentric out of gear.
The roller is made in three parts k, k³, k³, mounted freely on a shaft or
axle 1. This shaft or axle when the parts are in gear for propelling the
engine receives motion from the main shaft g, which is provided with a
sliding 'pinion n gearing into a toothed wheel o keyed on to an inter-
mediated crank shaft p, which transmits motion to the roller shaft or
axle by means of coupling rods q, as shewn.
The Drawing shews the parts in position for giving motion to the
roller shaft or axle so as to propel the engine, the pinion n being in
gear with the toothed wheel o. The roller shaft or axle 7 has keyed upon :
it three arms 7, 1, 73, to which are pivotted three catches or levers, one
of which is shewn at s; these catches or levers are forked at one end
and weighted at the other, there being one catch or lever to each arm.
The forked ends of the catches or levers take respectively into three
toothed bosses t, t, t, formed with or attached to the parts k, k¹, k², 2
respectively of the roller, so that as the roller shaft or axle rotates, the
catch or lever of the arm drives the part of the roller, the catch or
lever of the arm 7 drives the part k², and the catch or lever of the arm?³
drives the part k³, so nevertheless as to allow for any inequality in specd
arising from the different diameters of the several parts of the roller.
The arms r, ¹, and 7 are formed with holes at m, and corresponding
holes are formed in the catches or levers 8, so that by passing a pin
through the holes of any of the arms and its corresponding catch or
lever the latter may be locked out of gear and allow its part of the roller
to rotate freely on the shaft or axle Z.
I have not shewn all the details of the steam engine for giving motion

page_text: the ordinary construction, the cylinders being by preference attached, as
as shewn at u, to the boiler v, which may be constructed on Field's plan,
or may be of any other construction capable of generating steam rapidly
within a small compass.
The stone breaker or crusher may if desired be worked by a belt
passing round the pulley w, either from the fly wheel x or from another
engine, by disconnecting the rod h from the eccentric i and connecting
it with the eccentric y on the shaft 2.
Having described my said Invention of "Improvements in Road Rolling
Engines, whereby they are made suitable also for other Purposes," and
having explained the manner of carrying the same into practical effect,
I hereby declare that I claim as the Invention secured to me by Letters
Patent, the arrangement and construction of parts herein set forth for
rolling roads or such like surfacos, and breaking or crushing stones or
other hard substances.
In witness whereof, I, the said John Whittingham, have here-
unto set my hand and seal, this Seventeenth day of July, in
the year of our Lord One thousand eight hundred and seventy-
two.
