IMPROVEMENTS IN DRAWING TRAINS UP INCLINES AND IN MACHINERY THEREFOR, THE SAME BEING ALSO APPLICABLE TO OTHER HAULING OR WINDING OPERATIONS." PROVISIONAL SPECIFICATION
Year: 1874

page_text: LETTERS PATENT to Graham Stevenson, of Airdric, in the County
of Lanark, and John Reid, of Baillieston, in the same County, both
Engineers, for the Invention of "IMPROVEMENTS IN DRAWING TRAINS
UP INCLINES AND IN MACHINERY THEREFOR, THE SAME BEING ALSO APPLICABLE
TO OTHER HAULING OR WINDING OPERATIONS."
PROVISIONAL SPECIFICATION left by the said Graham Stevenson
and John Reid at the Office of the Commissioners of Patents, with
their Petition, on the 16th November 1874.
We, GRAHAM STEVENSON, of Airdrie, in the County of Lanark, and
JOHN REID, of Baillieston, in the same County, both Engineers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DRAWING TRAINS UP INCLINES AND IN MACHINERY THEREFOR, THE SAME BEING.
ALSO APPLICABLE TO OTHER. HAULING OR WINDING OPERATIONS," to be as follows,
that is to say:
-
This Invention has for its object to avoid the great expence of pro-
viding stationary engines for drawing trains up inclines, and to permit

page_text: of railways, particularly for mineral traffic, being constructed with
inclines, in many cases in which the cost of construction will be thereby
greatly reduced.
The improved arrangements are also applicable for various hauling or
winding operations, and will be very convenient and advantageous in
many cases as an inexpensive temporary, preliminary, or tentative ex-
pedient.
The Invention consists, according to one modification, in gearing to a
winding drum at the top of the incline one or more pairs of wheels, so
placed in an excavation below the line of railway that the tops of the
wheels are in line with the rails, and that a locomotive may be run upon
them, and being held from progressing may by driving its own wheels,
and, acting through them frictionally on the wheels below, drive the
winding drum. The machinery is by preference arranged in a siding,
and when there are two pairs of wheels (to be acted on by a locomotive
with two coupled pairs) they may be coupled by connecting rods, or
the two axles may both have pinions keyed on them to gear with the
same spur wheel on the winding drum shaft or on a shaft geared
thereto. By suitably proportioning the pinion and spur wheel gearing
any desired hauling force can be secured with correspondingly reduced
speed.
Instead of the wheels acted on by the locomotive wheels being con-
nected by spur gearing to a winding drum, they may have their axles
fitted with pulleys or drums for acting directly on an endless rope or
chain applied for hauling or winding.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Graham Stevenson and John Reid in the Great
Seal Patent Office on the 14th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GRAHAM
STEVENSON, of Airdrie, in the County of Lanark, and JOHN REID, of 3
Baillieston, in the same County, both Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing dato the Sixteenth day of November, in the year

page_text: of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Graham Stevenson and John Reid, Her
special licence that we, the said Graham Stevenson and John Reid,
our executors, administrators, and assigns, or such others as we, the said
Graham Stevenson and John Reid, 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 DRAWING TRAINS UP INCLINES
AND IN MACHINERY THEREFOR, THE SAME BEING ALSO APPLICABLE TO OTHER HAULING
OR WINDING OPERATIONS," upon the condition (amongst others) that we,
the said Graham Stevenson and John Reid, our executors or admini-
strators, by an instrument in writing under our, or their, 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 Graham Stevenson and John Reid,
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 in writing, reference
being had to the accompanying Drawings, that is to say:-
Our said Invention has for its object to avoid the great expence of
providing stationary engines for drawing trains up inclines, and to permit
of railways, particularly for mineral traffic, being constructed with
inclines, in many cases in which the cost of construction will be thereby
greatly reduced.
Our improved arrangements are also applicable for various hauling or
winding operations, and will be very convenient and advantageous in
many cases as an inexpensive temporary, preliminary, or tentative

page_text: purpose.
And in order that our said Invention and the manner of performing
the same may be properly understood, we hereunto append a Sheet of
explanatory Drawings, to be herein-after referred to, and representing by
way of example one modification of apparatus for carrying out our In-
vention. In these Drawings the same reference numerals mark the same
or like parts wherever they are repeated.
Figure 1 is a plan of winding gearing adapted for drawing a train of
wagons up a railway incline, and Figure 2 is a sectional side elevation
corresponding to Figure 1, but in addition showing a locomotive 3 as in
the position for actuating the winding gearing. The winding drum 4
and its gearing are mounted in suitable bearings on framing fixed in a
stone cased or brick cased excavation below the line of rails 5 on which
the locomotive 3 is brought to the spot. The shaft of the winding
drum 4 has fast on it a spur wheel 6 in gear with a pinion 7 on an
intermediate shaft 8, which has also fast on it a pinion 9 in gear with a
pinion 10 on one of a pair of shafts 11, 12. These shafts 11, 12, have
wheels 13 fixed on them, with their uppermost parts at the level of the
rails 5, and with cranks 14 on them connected by rods 15. The rails 5
are cut away at the parts where the tops of the wheels 13 are, and when
the locomotive 3, which is of a kind commonly used for mineral traffic,
and having two pairs of coupled wheels 16, is run into position up
against a buffer bar 17, its four wheels 16 rest on the four wheels 13
below, the entire weight of the locomotive serving to impart driving
pressure or adhesion. Then on the locomotive being made to drive its
own wheels 16, these, acting frictionally on the wheels 13 below, drive
the winding gearing. The rails 5 may form part of a siding, whilst the
winding drum 4 may be in the line of the incline.
Instead of connecting the wheels 13 by cranks and connecting rods,
their shafts or axles may both have pinions keyed on them to gear with
a spur wheel on the drum shaft or on a shaft geared thereto. By
suitably proportioning the pinion and spur wheel gearing any desired
hauling force can be secured, with of course correspondingly reduced
speed.

chain applied for hauling or winding.
Having thus particularly described our said Invention, and the
manner of performing the same, we have to state that we do not restrict
ourselves to the precise details herein described or delineated, but that
what we believe to be novel and original and claim as the Invention
secured to us by the herein-before in part recited Letters Patent is,
the drawing of trains up inclines, and the effecting of other hauling or
winding operations by means of stationary winding gear arranged to be
acted on by a locomotive steam engine, substantially as herein-before
described.
In witness whereof, I, the said Graham Stevenson, on behalf of
myself and the said John Reid, have hereunto set my hand and
seal, this Thirteenth day of May, in the year of our Lord One
thousand eight hundred and seventy-five.
Witness,
EDMUND HUNT,
Patent Agent,
