State of South Carolina, United States of America Machinist do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in locomotives and has for its object to
enable dry steam to be supplied to one only of the cylinders of the engine in case the
other engine becomes disabled.
The invention consists of a pair of steam pipes one for each engine provided with
separate regulators both of which regulators are detachably connected to a single
operating lever.
Each regulator or valve is attached to a rod which is pivoted to the short arm of
a bell crank lever, the long arm of which is connected to horizontal rods which
extend through stuffing boxes in the front plate of the boiler. The outer ends of
the rods are curved toward each other and are pivotally connected by bolts with the

placed one above the other so that the lever acts equally on both rods.
When both engines are to be supplied with steam, both rods are moved longi-
tudinally by means of the lever thereby raising the valves and admitting steam
simultaneously and in like amount to the steam pipes. By a reverse motion steam is
cut off from both pipes.
If one of the engines should become disabled one of the bolts is removed so that
the lever when moved outward or inward only acts on that one of the rods which is
still connected with the lever. When the lever is moved outward the rod is moved
so as to open its valve thus permitting the steam from the dome to pass to the engine
which is not disabled, while it is shut off from the other engine as the other valve
remains closed.

page_text: I, MIDDLETON GUERARD FULLER, of Ten Mile Hill, in the County of Berkeley, and
State of South Carolina United States of America, Machinist, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This Invention relates to improvements in locomotives, and has for its object to
enable dry steam to be supplied to one only of the cylinders of the engine in case the
other engine becomes disabled.
The Invention consists of a pair of steam pipes, one for each engine, provided with
separate regulators both of which regulators are attachably connected to a "single
operating lever.
Reference is to be had to the accompanying drawings forming part of this
specification, in which figure 1 is a sectional side elevation of the dome and upper part
of the boiler adjacent to the fire-box, shewing the improvement applied thereto,
Figure 2 is a plan view of the improvement; and figure 3 a sectional elevation of the
improvement, on line x-x figure 1; Figure 4 is a sectional front elevation of part of
the improvement, on line y-y figure 1; and figure 5 is an enlarged sectional view of
the lever, on line - figure 2. Similar letters of reference indicate corresponding
parts in all the figures.
A is the boiler of the locomotive, B the steam dome into which extend the two steam
pipes C and D, one leading from the dome to the one of the cylinders and the other
pipe leading to the other cylinder of the locomotive. The two pipes C and D may be
wholly separate or they may be in the form of a single pipe having a central division,
as shown in figure 3. E and F are the regulator valves controlling the admission of
steam to the pipes C and D in the steam dome B. The valves are respectively secured
to the rods I and I' which are each pivoted to the short arm of the bell-crank levers J
and K, the long arms of these levers being connected with the rods Land N which
extend through stuffing boxes in the front plate of the boiler. The outer ends of the
rods L and N are curved toward each other (see figure 2) and are pivotally connected
by the bolts O and P with the hand lever Q which is pivoted to the boiler front in
the usual manner. The bolts O and P are placed one above the other, as is plainly
shewn in figure 5, so that the lever Q acts equally on both rods Land N."
When both engines are to be supplied with steam, both 'rods' L'and 'N are moved
longitudinally in the direction of the arrow a¹ by means of lever Q thereby raising
valves E and F by means of the bell-crank levers J and K, and admitting, steam
simultaneously, and in like amount to the pipes and D. By a reverse motion,
steam is cut-off from both pipes. If one of the engines should become disabled, one
of the bolts O or P which connects the rod L or N with the valve E or F is removed
so that the lever. Q, when moved outward or inward, only acts on that one of the
rods L or N which is still connected with the lever by the bolt O or P. When the
lever Qis moved outward, the rod Lor N is moved so as to open its respective

page_text: valve E or F, thus permitting the steam from the dome B to pass to the engine which
is not disabled while it is shut off from the other engine, as the other valve remains
closed.
By the foregoing it will be seen that with one lever the driver is enabled to supply
steam simultaneously to both engines or to one only when the other engine is
disabled.
Having now particularly described and ascertained the nature of the said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination, with a locomotive boiler provided with a separate live steam
pipe for each engine and a regulator valve for each pipe, of a connecting rod for each
valve and a single lever to which the said rods are detachably connected, substantially
as shewn and described.
2. The combination, with two dry steam pipes leading to the two locomotive
engines, of valves held at the inner ends of said pipes, bell-crank levers connected
with the said valves, rods operating on the said bell-crank levers, and a hand lever
on which the said rods are pivoted at the same distance from the fulcrum point of
the said lever, substantially as shewn and described.
3. The combination, with a valve lever and two bolts held one above the other on
the said lever, of rods pivoted by the said bolts on the said valve lever, bell-crank
levers pivotally connected with the said rods, rods pivotally connected with the said
bell-crank levers, regulator valves held on the said rods, and dry steam pipes in
which the said valves operate, said pipes being connected with the two cylinders of
the locomotive, substantially as shewn and described.
4. The combination, with the locomotive boiler, of the pipes C, D, leading from the
engines of the locomotive to the steam dome, the valves E, F, in the said pipes, the
bell-crank levers J, K, the rods II' connecting the short arms of the bell-crank
levers with the valves, the rods L, N, connected to the long arms of the bell-crank
levers, and the lever to which the rods L, N, are detachably connected, substantially
as herein shewn and described.
