and other Shafts and Bearings.
I, GUSTAVUS ADOLPHUS JOHN SCHOTT, Manufacturer of Westend Mills, Richmond
Road Bradford in the County of York do hereby declare the nature of this invention
to be as follows
This invention consists in an improved Combination of Apparatus for the continuous
lubrication of Steam-engine and other Shafts and Bearings.
Under such Bearings are placed one or more troughs, which serve to contain a
supply of the oil or other lubricating liquid and to catch the droppings from such
Bearings. When more than one trough are used, the several troughs are connected
by tubes for the purpose of keeping the liquid contained in them at one level.
A Rotary Pump is mounted on a level with the bottom of the trough or troughs
and connected therewith by a tube in such a manner, that the lubricant contained in
the trough or troughs has access to the lower portion of the interior of the pump thus
keeping the pump primed; a sieve or strainer placed in the trough over the mouth
of the connecting tube serves to prevent coarse impurities from entering the pump.
The pump is caused to rotate slowly by means of driving belts or bands from the
Shaft in any convenient manner, by which means the lubricating liquid contained in
the troughs is lifted and forced upwards through tubing connecting the Outflow
opening of the pump with a Spreader mounted over the shaft and bearing to be
lubricated, into such Spreader, from which it drops continuously on to the shaft and
bearing, as long as the shaft and pump remain in motion. After thus lubricating
the shaft and bearing the surplus liquid runs back into the trough or troughs before
mentioned.

and other Shafts and Bearings.
I GUSTAVUS ADOLPHUS JOHN SCHOTT, Manufacturer of Westend Mills Richmond
Road, Bradford in the county of York, 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 consists in an improved combination of apparatus for the continuous
lubrication of steam engine and other shafts and bearings.
Below such bearings are placed one or more troughs of suitable forms and
dimensions, which serve to contain a supply of the oil or other lubricating liquid and
to collect the return flow from such bearings. When more than one trough are used,
the several troughs are connected by tubes for the purpose of keeping the liquid
contained in them at the proper level or passing the same forward from one to the
other as required.
A Rotary Pump of any suitable construction is mounted on a level with the lower-
most trough or one of them and connected therewith by a tube or otherwise suitably
in such a manner that the lubricant contained in such trough, which I call the supply
Reservoir, is free to enter by its own gravity the lower portion of the interior of the
pump thus keeping the same primed. A sieve or strainer placed in the supply
Reservoir over the connecting aperture serves to prevent coarse impurities from
entering the pump.
The pump is caused to rotate slowly by means of driving belts or bands from the
Engine Shaft or in any convenient manner, by which means the lubricating liquid is
lifted and forced through tubing connecting the Outflow opening of the pump with a
spreader mounted over the shaft & bearing to be lubricated, into such spreader, from
which it drops or flows continuously on to the shaft & bearing, as long as the pump
remains in motion. After thus lubricating the shaft & bearing the surplus liquid
runs back into the trough or troughs before mentioned.
Several bearings may in this manner be kept in a state of lubrication by means of
one pump, each such bearing having a spreader placed over it and such spreaders
being placed in communication with the pump by delivery tubing and one or more
troughs of suitable construction being placed under each bearing for the purpose of
collecting the flow, from which the lubricating liquid is conducted back to the trough,
which supplies the pump.
Fig. 1 illustrates my combined apparatus in a simple form as applied to the free
end of a steam engine shaft and its bearing.
A is a tin trough fitted under such bearing in such manner as to catch the lubricant
flowing from the bearing. A similar trough may be placed on the other side (not seen
in the diagram) of the bearing and the two troughs connected by an overflow tube
passing through holes drilled in the Engine bed. The lubricant contained in the
trough A passes through the sieve F and the tube G into the Rotary pump B, which
is of well known construction and is actuated by means of straps or bands I from the

page_text: Engine shaft. By the revolution of the pump the lubricant is forced up the Delivery
tube H into the spreader C, which preferably is of the width of the bearing and from
which it drops or flows on to the said bearing continuously whilst the pump B is in
motion.
Fig. 2 illustrates my combined apparatus as applied to the crankend of a steam
Engine shaft and its bearing, where there is generally too little space available for
applying the apparatus as illustrated in Fig. 1. fi fi are two tins in the form of
pouches, one being fixed on each side of the bearing for receiving the flow from the
bearing. They are connected by the tube g¹, which passes through the part of
Engine bed and establishes a communication for the lubricant. a is the crank,
cap of bearing, d' shaft, e¹ excentric, all parts of an ordinary horizontal steam-
engine, ¹ is a tube connecting one of the pouches f¹ with the supply reservoir A,
which contains a supply of the lubricant and is connected with the rotary pump B in
the manner described with reference to Fig. 1, from which the liquid passes through
the Delivery tube H into the spreader C.
cl
Fig. 3 is a front view in perspective of one of the pouches f¹ fig. 2. is an aperture
closed by a screwplug placed in line with the tube g¹ fig. 2 and which serves for
clearing such tube and the pouches f₁ f¹ of sediment when necessary.
It will be understood from the foregoing that the details of construction of my
apparatus may be varied according to the circumstances of each case and the space
available.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I claim is :
1. The Combination of parts substantially as and for the purpose set forth, con-
sisting of a Rotary Pump connected with a supply reservoir, from which the lubricant
passes by its own gravity through a sieve into the pump, and is forced therefrom
through Delivery tubing into a spreader, from which it flows over the shaft and
bearing and back into the supply reservoir either directly or by way of one or more
additional troughs suitably constructed, and connected with the supply reservoir.
2. The Combination of parts substantially as and for the purpose set forth, con-
sisting of a Rotary Pump connected with a supply reservoir in such manner, that the
lubricant passes by its own weight through a sieve into the pump and is forced
therefrom through tubing into as many spreaders as there are bearings to be lubricated,
and flows from such spreaders over their respective bearings into troughs of suitable
number, construction and position for collecting such flow and passing it back to the
supply reservoir.
