I, WALTER MARTIN MUSGRAVE, of the Firm of John Musgrave and Sons
Limited, of Globe Iron Works, Bolton, in the County of Lancaster, Engineers,
Millwrights, Boiler Makers, and Iron Founders, do hereby declare the nature of my
said invention to be as follows:-
This invention relates to improvements in the construction of vertical compound
steam engines and in apparatus for automatically lubricating the same, and is
designed and arranged in a compact and self-contained manner. On a framework
of box form is mounted an enclosed stand or frame provided with a hinged door
secured and locked in any convenient manner. On the upper end of the said stand
or frame are mounted the high-pressure and low-pressure cylinders provided with
piston valves and valve-boxes by which the cylinders are brought into close proximity
with each other. 'Inside the stand or frame are disposed slide-bars on which are
mounted slide-blocks connected with the head of each piston rod. The piston rods
are coupled to balanced sweep cranks by connecting rods. The crank shaft is
mounted in side and middle bearings and is provided at one end with what is well
known as a crank shaft governor for regulating the speed of the engine. If desired
any other suitable governor may be employed for operating a throttle valve. The
valve spindles and piston valves are operated by eccentrics and rods from the crank
shaft. The latter is provided with a fly wheel, or a strap or rope pulley for
transmitting power by belt or ropes, or the crank shaft may be coupled direct to
any machine. The crank shaft governor and the eccentrics for operating the valves
are enclosed in stationary boxes and covers containing oil or lubricant. My improved
apparatus for automatically lubricating the movable parts, wearing surfaces, and the
like of vertical engines consists in providing the base or foundation plate with an
oil well or reservoir in which is located a pump, the ram of which is actuated by an
eccentric and rod or other mechanical means from the crank shaft. The pump is fitted
with valve-boxes and valves on the ball or other principle. The oil or lubricant is
raised from the well or reservoir and forced through pipes to a box or chamber which
is provided on each side with a parallel motion consisting of pipes and couplings to
compensate for the vertical movements of the cross-head to which the same is
attached. The oil or lubricant is forced into the crosshead pin on one side to
lubricate from whence it is forced by the pump out on the other side and down pipes
connecting the same with the crank pin. In lieu of the before mentioned parallel
motion I insert in each slide bar a pipe coupling by means of a passage with the
surface of the slide bars, and by the movements of the slide block of the crosshead
the surplus oil or lubricant is admitted through an opening to the centre pin of the
crosshead attaching the connecting rod thereto, from whence the oil or lubricant
flows down a pipe to the crank pin. To the main pipe leading from the oil pump
are coupled other pipes from which oil or lubricant flows to the crank shaft bearings,
the surplus flowing back to the oil well or reservoir to be used over again. For the
DQ71

page_text: purpose of lubricating eccentric for pump and other parts suitable "drip" pipes and
taps may be employed. The eccentric may be lubricated by oil or lubricant which
flows from the crank shaft pedestal coming in contact with suitable openings and a
plate secured to the eccentric ring. The pipes are fitted with union joints and
couplings where necessary for the purpose of fixing or removing the same when
desired or necessary. The crank shaft and other parts are provided where necessary
with dripping points to prevent oil or lubricant being drawn or forced outside the
framing thus ensuring of outside cleanliness.

I, WALTER MARTIN MUSGRAVE, of the Firm of John Musgrave and Sons Limited,
of Globe Iron Works, Bolton, in the County of Lancaster, Engineers, Millwrights,
Boiler Makers, and Iron Founders, do hereby declare the nature of iny said invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention relates to improvements in the construction of vertical compound
steam engines and in apparatus for automatically lubricating the same, and is designed
and arranged in a compact and self-contained manner. On a framework of box form
is mounted an enclosed stand or frame provided with a door or cover secured in any

C is the high-pressure cylinder; D low-pressure cylinder; E high-pressure
cylinder piston rod; G low-pressure cylinder piston rod; H connecting rods; I
balanced sweep cranks; J crank pins; K crank shaft; L crank shaft pedestals;
M fly wheel; N eccentrics; 0 eccentric rods; P valve spindles; Q valve-boxes, and
R foundation or framework of box form.
On the foundation or framework R is mounted the enclosed stand or frame S
provided with the door or cover T secured in any convenient manner.
On the upper
end of the stand or frame S are mounted the high-pressure cylinder C and the
low-pressure cylinder D provided with the valve-boxes Q; the latter being, fitted
with the piston valves U. The valve-boxes Q are disposed on the outside by which
the steam cylinders C and D are brought into close proximity with each other. Inside
the stand or frame S are disposed the slide-bars V on which are mounted the slide-
blocks W connected to or formed with the heads X of the piston rods E and G. The
piston rods E and G are coupled to the balanced sweep cranks I and crank pins J by
the connecting rods H. The crank shaft K is mounted in the side and middle bearings
or pedestals J, being held therein by the caps Y secured by bolts. The valve
spindles P and piston valves U are operated by the eccentrics N and eccentric rods ()
from the crank shaft K. The latter is fitted with the fly-wheel M, which may be,
substituted by a strap or rope pulley for transmitting power by belts or ropes, or the
crank shaft K inay he coupled direct to any machine by means of the shaft (a) and
coupling (b) bolted to the boss or centre (c) of the fly-wheel M as shown in Figs. 1, 2
and 4 in the annexed drawings. The eccentrics N for operating the piston valves U
are enclosed in the stationary boxes or covers (d) secured by bolts or their equivalents
to the sides of the stand or frame S and the foundation or framework R.
My improved apparatus for automatically lubricating the movable parts, wearing
surfaces, and the like of vertical engines consists in providing the foundation or
framework R with the oil well or reservoir (f) in which is located the pump (h); the
ram () of the same being actuated by the eccentric (l) and rod (m) from the crank;
shaft K. The pump () is fitted with the valve-box (n) provided internally with
valves on the ball or other principle. The oil or lubricant is drawn from the oil well
or reservoir (f) through the suction pipe (p) into the valve-box (n) by the outward
stroke of the rain (j), and forced from the same by the downward stroke which forces
the oil or lubricant up the pipe (7) and through the valve (t) into the pipes (v).

page_text: connected with the caps or covers Y of the crank shaft pedestals L. The pipes (v)
are provided with the couplings (x) secured to the underside of the slide-bars V, and
in line with the passage (w) leading to the slide blocks W on the slide-bars V, and as
the slide blocks W slide or move up and down the oil or lubricant is forced through
the hole or opening (a2) into the crosshead pin (62) to lubricate the centre (62), from
whence the oil or lubricant is forced by the action of the ram (j) of the pump out
through and down the pipes (2) connecting the same with the crank pins J. By this
arrangement the surplus oil or lubricant flows back to the oil well or reservoir (✗✓) to
be used over again, the operation being continuously repeated as long as the engine
is in motion. The crank shaft K is provided with the dripping points (s) turned or
formed thereon to prevent oil or lubricant being drawn or forced outside the framing
of the engine. The arrangement of my improved apparatus for lubricating the afore-
said movable parts by means of a parallel motion as shown in Figs. 4 and 5 consists
in providing the foundation or framework R with the oil well or reservoir (f) in which
is located the pump (h); the ram (j) of the same being actuated by the eccentric (1)
and rod (m) from the crank shaft K. The pump (h) is fitted with the valve-boxes (n)
provided internally with valves on the ball or other principle. The oil or lubricant
is drawn from the oil well or reservoir (f), through the suction pipe (p) into the valve-
box (n) by the outward stroke of the ram (j), and forced from the same by the down-
ward stroke of the ram, which action forces the oil or lubricant up the pipe (r) and
through the tee (1) into the pipes (v) leading to the caps or covers Y of the crank
shaft pedestals L. The pipes (v) are provided with the coupling (x) secured by the
pipe (82) to the box or chamber (m²) which is provided on each side with a parallel
motion consisting of the pipes (h2) and couplings () to compensate for the vertical
movements of the crosshead X of the piston rods E and G. The oil or lubricant is
forced by the action of the pump (h) through the pipes (2) and couplings (12) into
the crosshead pins (62) on one side to lubricate the same and from whence it is forced
out on the other side by the action of the pump (h) and down the pipes (2) leading to
the crank pins J. The oil or lubricant also passes up the pipe (32) and through the
aperture (t³) from whence the slides V are lubricated. The surplus oil or lubricant
which flows back to the oil well or reservoir (f) is used over and over again as long as
the engine is in motion. For lubricating the eccentrics N each end of the pipe (v) is
provided with a pipe (v). The pipes for conveying oil or lubricant are fitted with
union joints and couplings where necessary for the purpose of fixing or removing the
same when desired or necessary. If desired the engine may be provided with what
is known as a crank shaft governor 7 shown in Fig. 4 of the drawings, or any
other suitable governor may be employed for operating a throttle valve. In case an
ordinary ball or other governor is employed for controlling the speed of the engine it
may be fixed in any desired position and driven by bands or ropes from the
grooves (a) on the end of the crank shaft K.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The general arrangement construction and combination of parts composing my

of the crank shaft pedestals L, also through the couplings (a) secured to the under-
side of the slide-bars V and into the passage (w) leading to the slide blocks W, from
whence the lubricant is forced through the hole or opening (a2) into the crosshead
