Year: 1866

page_text: LETTERS PATENT to Joseph Ward, of Gorton, near Manchester, in the
County of Lancaster, and Joseph Smales, of Leeds, in the County of
York, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR FACILITATING THE ADJUSTMENT AND TESTING THE WORKING PARTS OF
LOCOMOTIVE ENGINES"
Sealed the 11th January 1867, and dated the 12th July 1866.
PROVISIONAL SPECIFICATION left by the said Joseph Ward and Joseph
Smales at the Office of the Commissioners of Patents, with then
Petition, on the 12th July 1866.
We, JOSEPH WARD, of Gorton, near Manchester, in the County of
Lancaster, and JOSEPH SMALES, of Leeds, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR FACILITATING THE ADJUSTMENT AND TESTING THE WORKING PARTS
OF LOCOMOTIVE ENGINES," to be as follows.―
This Invention consists in improved machinery or apparatus for turning
the diving wheels of locomotive engines, and giving motion to the working
parts without steam, and without any travelling movement of the engine
horizontally, for the purpose of enabling the fitter or erector to set or adjust
the valves without the use of pinch bars or screw Jacks, and also for testing
the condition of the working parts.

page_text: In the workshop or engine shed we form in any convenient position under
a line of rails a rectangular pit, into which we place two frames, each having
at the top short rails in line with the main rails, and level with them. In
each frame there are vertical guides, in which is fitted a pedestal resting at
the bottom on the head of a screw enclosed in a nut, and carrying at the
top a disc wheel, and also a spur or worm wheel gearing into a pinion or
worm, to which revolving motion is given by hand or motive power, and when
the nuts are turned the screws are raised or lowered, and with them the
pedestals and wheels. The outsides of the short rails at the top of the frames
are slightly recessed to enable the disc wheels to be under the driving wheels
of the engine, and when the tops of the disc wheels are below the level of the
rails the engine can be moved to and fro bodily, but when the driving wheels
are over the disc wheels, and the tops of the disc wheels raised by means of
the nuts and screws just above the level of the rails the apparatus will then
be ready for work; and if the pinion or worm be turned by hand or power
the disc wheels will revolve and turn the driving wheels, and give motion to
all the working parts of the engine, it being understood that in coupled
engines the outside connecting rods are disconnected, and in all cases one pair
of wheels are scotched on the main rails to prevent the engine from moving
bodily Thus by means of our improved machinery or apparatus the diving
wheels of the engine can be propelled when there is no steam, and all the
under works put in motion, and consequently the great loss of time and
expense of the labour in moving the engines by pinch bars and lifting by
screw jacks are avoided.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Ward and Joseph Smales in the Great Seal Patent
Office on the 11th January 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPHI
WARD, of Gorton, near Manchester, in the County of Lancaster, and JOSEPH
SMALES, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of July, in the year of our Lord One
thousand eight bundied and sixty-six, in the thirtieth year of Her reign,
did, for Jerself, lle hens and successors, give and grant unto us, the said
Joseph Ward and Joseph Smales, Her special license that we, the said Joseph

such others as we, the said Joseph Ward and Joseph Smales, our 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 MACHINERY OR APPARATUS FOR
FACILITATING THE ADJUSTMENT AND TESTING THE WORKING PARTS OF Loco-
MOTIVE ENGINES," upon the condition (amongst others) that we, the said
Joseph Ward and Joseph Smales, our executors or administrators, by an
instrument in writing under our, on then, or one of their hands and seals,
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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Joseph Waid and Joseph Smales, do
hereby declare the nature of our said 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) -
This Invention consists in improved inachinery or apparatus for turning tho
driving wheels of locomotive engines, and giving motion to the working paits
without steam and without any travelling movement of the engine horizontally,
for the purpose of enabling the fitter or erector to set or adjust the valves
without the use of pinch bars or screw Jacks, and also for testing the condition
of the working paits
In the workshop or engine shed we form in any convenient position under
a railway line two rectangular pits, one under each line of rails, into which
pits we place two fiames, each having fitted into it at the top a short rail in
line with the mam rails, and level with them. In each frame there are
vertical guides in which is fitted a pedestal resting at the bottom on the head
of a screw enclosed in a nut, and carrying at the top a shaft to which is fixed
a disc wheel and also a spur or worm wheel gearing into a pinion or woim,
to which revolving motion is given by hand or motive power, and when the
nuts are turned the screws are raised or lowered, and with them the pedestals
and wheels. The outsides of the fitted short rails at the top of the frames
are slightly recessed to enable the disc wheels to be under the driving wheels
of the engine, and when the tops of the disc wheels are below the level of the
rails the engine can be moved to and fro bodily, but when the driving wheels
are over the disc wheel-, and the tops of the disc wheels raised by means of

page_text: the nuts and screws just above the level of the rails, the apparatus will then
be ready for work, and if the pinion or worm be turned by hand or power
the disc wheels will revolve and turn the driving wheels, and give motion to
all the working parts of the engine, it being understood that in coupled
engines the outside connecting rods are disconnected, and in all cases one
pair of wheels are scotched on the main rails to prevent the engine from
moving bodily
These improvements will be clearly understood by the following detailed
desciption thereof, reference be ng had to the figures and letters on the
accompanying Sheet of Drawings, in which Fig 1 is a longitudinal elevation,
and Fig 2 a transverse section of one of our improved arrangements of
machinery for working the engine without steam; Fig. 3 is a plan of Fig 1
and also a plan in which similar machinery is supposed to be covered by a shield
or plate, and Fig. 4 an elevation shewing a modified arrangement for working
the machine In the workshop or engine shed there is a longitudinal pit
between the 1ails for enabling the operatives to attend to the under working
parts of the engine, and it is at the sides of this pit that we form the
rectangular pits, into each of which we place our machinery or apparatus, and
as the arrangements of both sides are similar a description of one side will
suffice for both. In Figs. 1 and 3, a represents part of the main lines of the
railway; b, Figs 2 and 3, the ordinary pit between the rails, at the sides of
which are the additional rectangular pits for the reception of the machinery.
In each of the pits there is a foundation plate and frame d, e, having at the
top chairs f, into which is fitted and fixed a short rail g in line with the man
In the frame e there are vertical cheeks or guides h in which is
fitted the pedestal which rests on the head of the screw fitted to the nut k,
resting on the foundation plate. The pedestal carries at the top a shaft l, to
which is fixed the disc wheel m and the spui wheel n, the latter gearing into
the spur pinion o fixed to the shaft p, which canes at the other end the
bevil wheel geaning into the bevil pinion r fixed to the shaft s, which also
caties the bevil wheel t geaning into the bevil pinion on the driving shaft v,
one end of which carnes the winch or handle w. The metal below the
screwed part of the screw 7 is formed of a square shape, as at a, and fitted
into a square hole in the foundation plate d, so that when the nut & is turned
the sciew can be raised or lowered, and with it the pedestal 1, the shaft l,
the disc wheel m, and the spur wheel n. The outsides of the fitted shoit
rails are recessed as shewn at y, Figs. 2 and 3, for enabling the disc wheels
to be under the driving wheels of the engine, and for keeping the two
machines one at each side constantly the same distance from each other, we
rails a.

page_text: connect them together by a strong tie bar z When the tops of the disc
wheels are below the level of the rails the engine can traverse to and fro in the
usual manner, but when the valves of the engine have to be set, or the working
parts to be tested, the driving wheels are brought over the disc wheels, the steam
blown off, and the engine scotched; and if a coupled engine the outside connect-
ing rods are disconnected; the screws and disc wheels of both machines are
now raised by turning the nuts until the diving wheels of the engine are
above the rails, and then the two machines are worked by means of the
winches so as to give a slow revolving motion to the disc wheels, which in
their turn cause the driving wheels to revolve and give motion to the valves,
pistons, and under working parts of the engine. And thus means of our
improved machinery or apparatus the driving wheels of the engine can be
propelled when there is no steam and all the under works put in motion,
and consequently the great loss of time and expense of the labour in moving
the engines by pinch bars on hand spikes and lifting by sciew jacks are
avoided. We make the disc wheels of any required diameter and strength,
either of cast or malleable iron, or of iron covered with tyres of steel, and
form the peripheries of the wheels either plain or roughened, and when
desired we form hollows in the disc wheels, and place the wheels in the
insides of the rails so that the flanges of the driving wheels of the engine
shall correspond with the hollows, and in this case there will be no
necessity for making recesses in the short rails g. The bottom ends of the
Sciews aic square, but they may be of any other suitable shape; if round
there must be keys to prevent the screws from turning, and though we prefei
screws and nuts, racks and worns may be substituted for them. The gearing
for obtaining power and giving slow revolving motion to the disc wheels,
may be modified in any suitable manner, and when desired the driving shafts
and winches for turning the machines may be above the ground, as shewn in
Fig. 4, and worms and worm wheels may be employed in conjunction with spur
gearing. The gearing of both machines may also be connected together by
one or more shafts below the ordinary pit, so that the motion of one machine
shall be transmitted to the other, and when desired the machines may be
worked by a belt or toothed wheels from a revolving shaft diven by a steam
engine or other motive power.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we do not claim any of the parts of the machinery or
apparatus separately; but what we claim is, the combination in each machine
or apparatus of the fitted short rail, the disc wheel, and the sciew and nut, or

page_text: its equivalent, for enabling locomotive engines to be worked without steam, as
such improvements are herein described and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, we, the said Joseph Ward and Joseph Smales, have
hereunto set our hands and seals, this Eighth day of January, in the
year of our Lord One thousand eight hundred and sixty-seven.
Signed, sealed, and delivered, by the
within-named Joseph Ward and
Joseph Smales, in the presence of
