Improvements in Steam Hoisting Engines.
We, JOSEPH TEMPERLEY and JOHN RIDLEY TEMPERLEY, both of The Temperley
Transporter Company, 72, Bishopsgate Street Within, in the City of London,
Engineers, 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 direct acting steam engines for high speed hoisting,
and mainly applicable for use with Temperley transporters.
The engine has two cylinders carried on independent frames which are rigidly
connected by distance bars whose length is chosen to suit any desired length of
hoisting drum.
The central hoisting drum of any desired diameter and length is permanently
keyed on the main shaft of the engine and when the drum is used ior hoisting,
the engines run silently, the intention being that this is the normal and usual
condition of working.
Auxiliary warping drums are keyed on a counter-shaft carried in bearings on
the engine frames parallel to the engine shaft and arranged to be geared to
the said shaft by spur wheels one of which is keyed permanently in position,
while the other is made to slide on a feather on its shaft and can be thrown in
and out of gear as may be required.
The warping drums, countershaft and spur wheel are arranged to be readily
removed and stowed away until required. They are mainly intended for work-
ing "whips" in the event of a breakdown in the transporter gear, or in the
event of circumstances preventing the use of transporters.
We sometimes provide an auxiliary drum on this countershaft to be used for
bauling transporters into position or for other purposes of like kind.
A steam reversing valve is used instead of link motion for reversing the
engine when lowering a load, thus entirely dispensing with link motion. The
engine slide valves being set for forward running are not advantageously disposed
for reverse running, but as the engine when running reversely has nothing to
do but help the load to overhaul the drum, this is not detrimental.
This steam reversing valve is made in a special manner so that when it is
placed at mid position it admits steam to all parts of the cylinders simultaneously
and so gives great facility for heating the engine immediately before starting
it.
Referring to the accompanying drawings which illustrate our improvements.
Figure 1 is a side elevation, and
Figure 2 is a plan, of the engine.
Figure is a horizontal central section of the reversing valve, drawn to a
larger scale, the valve being shown in its mean position.
Figure is a section, taken on the line X, Y, of Figure 3, looking towards
the night

page_text: Figure 5 is a section taken on the line Z, Z, of Figure 3, looking towards
the left, and
Figures 6 and 7 are sections of the valve and ports similar to Figure 3 but
showing the valve in its two extreme positions.
Like letters of reference denote corresponding parts in the several figures.
A, A are the engine cylinders; B, B the frames which are rigidly connected
by transverse distance bars E; C is the main or-crank shaft; and D the hoisting
drum which is permanently keyed on the shaft C. The length of the bars E
is chosen to suit any desired length of drum.
The frames are constructed with bearings F to carry a warping drum shaft G,
which is geared with the shaft C by spur wheels H, H; the latter being con-
nected to its shaft by a feather key h to admit of said wheel sliding on the shaft
to a position where it is out of gear with the driving wheel H. D₁ is an auxiliary
drum provided on the shaft G for hauling transporters into position and for other
like purposes.
The brakes J are applied to the crank discs I and are actuated by a foot lever K
acting through a shaft K' and arms K² fixed on the shaft and coupled to the
free ends of the brake straps. The length of the brake straps can be regulated
by means of adjusting nuts or sleeves L engaging with right and left hand
screws L, L. L³, L2 are lock nuts for locking the adjusting sleeve.
The steam reversing valve comprises a valve proper M of the ordinary ☐ pattern
working in a valve chamber M' and serving to control the three port openings N,
O and P which are arranged like the ports in a steam engine valve chest. The
port N as shown in Figure 5 communicates with the pipe N¹ which is connected
direct to the steam chest of the adjacent cylinder; and the same port also com-
municates through the opening N, Figure 5, and the pipe Q Figure 2 with
the steam chest of the other cylinder.
The central port O communicates by way of the outlet O¹ Figures 3, 4 and 5
with the exhaust pipe R, Figure 1, and the port P' communicates through the
pipe P, Figure 1, with the exhaust outlet of the cylinder valve chest. This port
also communicates by the pipe S, Figure 2, with the exhaust outlet of the other
cylinder. The steam enters the chamber M from the steam pipe T through the
inlet M Figure 3.
The action of this valve is as follows; that is to say, when the valve M is
moved to the extreme position shown in Figure 6, steam is admitted through
the port N to the steam chests of the two cylinders and the engine is driven in
the forward direction for hoisting purposes. The exhaust steam returns from the
exhaust outlets of the steam chests through the port P of the reversing valve,
and out through the port O and the exhaust pipe R. On the other hand when
the reversing valve is moved to the other extreme position shown in Figure 7
the steam enters by the port P and passes into the exhaust ports of the steam
, chests underneath the slide valves and drives the engine in the reverse direction.
The exhaust steam in this case returns from the steam chests through the port N
of the reversing valve, and out again through the centre port Û to the exhaust
pipe R. The steam is not being used to the best advantage when working the
engine in the reverse direction, but, for the purposes required, this is not
important. Provision is made whereby the slide valves will not lift or will only
lift very slightly, when the steam is admitted beneath them.
The reversing valve is constructed with negative outside lap so that when
placed in the mean position indicated in Figure 3, steam may be admitted to
both ports N and P at the same time, whence it passes into the cylinders on both
sides of the pistons. In this way great facility is afforded for heating the cylinders
previous to starting the engine. Before admitting the steam, the cylinder drain
cocks V are opened, and the brake applied to prevent risk of starting the engine.
The reversing valve is moved by means of a pivoted lever U connected to the
spindle of the valve, and working in a quadrant guide U¹. U is a catch adapted

page_text: to engage with notches in the guide for locking the lever in its mid position or
in either of its extreme positions.
In the steam pipe above the reversing valve is arranged a regulating valve W
actuated by means of a handle W₁ for controlling the admission of steam to the
engine.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. A direct acting steam hoisting engine, constructed with two independent
frames connected by means of distance bars, substantially as described, and for
the purpose specified.
2. In a direct acting steam engine a reversing valve constructed with ports
and passages arranged substantially as described, with reference to the accom-
panying drawings, for the purpose specified.
3. The construction of the reversing valve, so that steam can be admitted to
both sides of the pistons at the same time, for the purpose specified.
4. The construction of the engine with auxiliary warping drums on a counter-
shaft, actuated by gearing which can be disengaged, substantially as, and for
the purpose, described.
5. The direct acting steam hoisting engine constructed with its various parts
in combination, substantially as described, with reference to the accompanying
drawings.
