IMPROVE- MENTS IN LOCOMOTIVE CRANES
Year: 1874

page_text: LETTERS PATENT to James Reid, of Glasgow, in the County of
Lanark, North Britain, Engineer, for the Invention of "IMPROVE-
MENTS IN LOCOMOTIVE CRANES.”
Scaled the 13th May 1875, and dated the 21st November 1874.
PROVISIONAL SPECIFICATION left by the said James Reid at the
Office of the Commissioners of Patents, with his Petition, on the
21st November 1874.
I, JAMES REID, of Glasgow, in the County of Lanark, North Britain,
Engineer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN LOCOMOTIVE CRANES," to be as follows, that is to say :—
This Invention has for its object the combining of crane details with
a locomotive steam engine in an improved and simplified manner and so
that the crane can be used for raising goods or heavy articles either at
the side of the locomotive or beyond the end of it; as, for example, in
loading or unloading a truck either on a parallel line of rails or on the
same line of rails as that on which the locomotive happens to be.

page_text: In carrying out the Invention the chimney or funnel and the top of
the smoke box of the locomotive are made of sufficient strength for
carrying the crane details and weight to be lifted, and these parts are
arranged so as to be capable of turning round the chimney as upon an
ordinary vertical crane post.
The construction and arrangement of the crane details may be varied,
but in a preferable modification they comprise two side plates extended
in one direction and suitably shaped to form the overhanging jib, whilst
they are attached to upper and lower castings or forgings which encircle
the chimney and which are fitted with antifriction rollers to case the
turning movement round the chimney, the rollers of the lower casting
running on a base plate on the top of the smoke box. The winding
barrel is arranged on the jib side of the chimney space, and a spur wheel
on the barrel shaft has in gear with it a pinion on a crank shaft,
arranged at the lower part on the other side of the chimney space. The
crank shaft is actuated by a pair of inverted cylinders with valves
worked by two single eccentrics, the reversing being effected by means
of a third valve, or there may be two pairs of eccentrics with the usual
reversing link.
The steam is supplied to the cylinders by a pipe carried up the centre
of the locomotive chimney, and the rod for working the reversing valve
passes down this steam pipe in the chimney, and issuing by a stuffing
box below is connected by links and levers to a hand lever at the foot
plate. A driver or workman on the foot plate can thus attend to the
movements of the cranc as well as to those of the locomotive without
changing his position.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Reid in the Great Seal Patent Office on
the 20th May 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES 3
REID, of Glasgow, in the County of Lanark, North Britain, Engincer,
send greeting.

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 me, the said James Reid, Her special licence that
I, the said James Reid, my executors, administrators, and assigns,'
or such others as I, the said James Reid, my executors, adminis-
-trators, and assigns, should at any time agrec with, and no others,
from time to. time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, excrcise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN LOCOMOTIVE
CRANES," upon the condition (amongst others) that I, the said James
Reid, 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
Scal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Reid, do hereby declare
the nature of my 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 accom.
panying Drawing, that is to say:-
My said Invention has for its object the combining of crane details with
a locomotive steam engine in an improved and simplified manner, and
so that the crane can be used for raising goods or licavy articles cither
at the side of the locomotive or beyond the end of it; as, for example,
in loading or unloading a truck either on a parallel line of rails or on
the same line of rails as that on which the locomotive happens to be.
And in order that my said Invention and the manner of performing
the same may be properly understood I hereunto append a Sheet of
explanatory Drawings, to be herein-after referred to, and representing a
locomotive crane as constructed with my improvements. In these
Drawings the same reference numerals are used to mark the same or
like parts wherever they are repeated.
Figure 1 of the Drawings is a sectional side elevation and Figure 2 is
a transverse vertical section. In these Drawings various minor details
of construction are omitted, as being well understood by makers of
locomotives and steam cranes,

page_text: In carrying out my Invention I make the chimney or funnel 3 and
the top 4 of the smoke box of the locomotive of sufficient strength for
carrying the crane details and weight to be lifted, and I arrange the
crane details so as to be capable of turning round the chimney 3' as
upon an ordinary vertical crane post.
. The construction and arrangement of the crane details may be varied,
but in the modification shown in the Drawings, and which I prefer,
they comprise two side plates 5 extended in one direction and suitably
shaped to form the overhanging jib 6, whilst they are attached to upper
and lower castings (or forgings) 7, 8, which encircle the chimney 3, and
which are fitted with antifriction rollers 9, 10, to ease the turning move-
ment round the chimney, the roller or rollers 10 or the lower casting 8
being conical and running on a base plate 4 on or forming the top of
the smoke box; the winding barrel 11 carried in bearings in the side
plates 5 is arranged on the jib side of the chimney space, and a spur
wheel 12, indicated by a dotted pitch circle in Figure 1, and which is
keyed on the barrel shaft, has in gear with it a pinion 13 on the crank
shaft 14, arranged at the lower part on the other side of the chimney
space; the crank shaft 14 is actuated by a pair of inverted cylinders 15
with valves worked by two single eccentrics 16, the reversing being
effected by means of a third valve (or the valves may be worked with
two pairs of eccentrics and the usual reversing link).
.The steam is supplied to the cylinders 15 by a pipe 17 carried up the
centre of the locomotive chimney 3, and a rod 18 for working the
reversing valve passes down this steam pipe 17 in the chimney, and
issuing by a stuffing box below is connected by links and levers (not
shown) to a hand lever at, the foot plate 19 of the locomotive. A driver
or workman on the foot plate 19 can thus attend to the movements of
the crane as well as to those of the locomotive without changing his
position. The top of the steam pipe 17 is connected by a swivel.joint 19
to a branch 20 carried by a bracket 21, and leading to the casing 22 of
the third valve; and the same bracket 21 carries a lever 23, to one end
of which is jointed the rod 18, whilst to the other end there is jointed
the rod 24 connected to the third valve. The exhaust steam passes by
two pipes 25, indicated by dotted lines in Figure 1, and which deliver it
just over the top edge of the chimney 3.
Having thus particularly described my said Invention, and the manner

page_text: the precise details herein described or delincated, but that what I believe
to be novel and original and claim as the Invention secured to me by
the herein-before in part recited Letters Patent is, the construction of a
locomotive crane with the parts adapted to cach other so that the
chimney serves as the cranc post, substantially in the manner herein
described and delineated.
In witness whereof, I, the said James Reid, have hereunto set my
hand and seal, this Nineteenth day of May, in the year of our
Lord. One thousand eight hundred and seventy-five.

EDMUND HUNT,
Patent Agent,
Glasgow.
