PROVISIONAL SPECIFICATION.
A Mode of and Means for Electrically Controlling Lubricators.
We, PERCY ROSLING, and FREDERICK JOSEPH ARUNDEL MATTHEWS, both
of 14 Trafalgar Street, Bradford, in the County of York, Electrical Engineers, do
hereby declare the nature of this invention to be as follows:-
It refers and is applicable to lubricating-appliances such as allow the lubricant
to pass forward from a cup or reservoir by gravity, or to those in which it is fed
forward by pressure.
The object is to provide a mode and means for simultaneously starting and
stopping lubricators without individual attention being required for each one i
thereby rendering it possible for a great number to be placed under the charge of
one attendant. In certain cases the lubricators may be arranged to start and stop
automatically and so prevent their being forgotten. Considerable economy results
from not allowing self-feeding lubricators to remain in action for a moment longer
than is necessary, and this our invention provides for.
We accomplish our object as follows:-
The valve or stopper of the lubricator is directly or otherwise connected with an
electro-magnet in such a manner that the valve is moved towards its open position
when the circuit is completed, by the attraction of the armature to the magnet;
when the current is broken, and the armature falls away, the valve is again
closed.
The necessary electric current may be supplied by and from any dynamo electric
machinery, or from primary or secondary batteries.
When the current is laid on direct from a dynamo, or the like, it follows that
the lubricators are put in and out of action when the dynamo is started and
stopped.
When a lubricator, instead of having a gravitation feed, depends upon the action
of a spring or other equivalent for producing pressure, the armature when drawn to
the magnet by the current must be arranged to allow the spring to act, and when
the current ceases, and the armature falls away, a counterweight or other such
appliance counteracts the pressure of the spring.
Each lubricator may be made to display or set in motion a danger signal
when the armature is out of action, so that, when the attendant knows the
current to be on, he may be warned by the said signal that something is wrong.
When an entire factory is fitted throughout with our lubricators the whole of
them may be started and stopped by the starting and stopping of the engine
producing the current; or otherwise by the movement of a single switch.
In cases where it is desired to start the lubricators before the dynamo machinery
is put in motion the current must be temporarily (or permanently) supplied
from batteries.

We,
PERCY ROSLING, and FREDERICK JOSEPH ARUNDEL MATTHEWS, both
of 14 Trafalgar Street, Bradford, in the County of York, Electrical 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 :-
It refers and is applicable to lubricating appliances such as allow the lubricant
to pass forward from a cup or reservoir by gravity.
The object is to provide a mode and means for simultaneously starting and
stopping lubricators without individual attention being required for each one ;
thereby rendering it possible for a great number to be placed under the charge of
one attendant. In certain cases the lubricators may be arranged to start and stop
automatically and so prevent their being forgotten. Considerable economy results
from not allowing self-feeding lubricators to remain in action for a moment longer
than is necessary, and this our invention provides for.
In order to explain our meaning fully we have annexed a drawing on which
Fig. 1 may be taken as showing a section through a complete lubricator.
Fig. 2 as a section through a cover &c. of a lubricator fitted with a "danger"
signal, and Fig. 3 as a plan of the same. To adjust the feed spindle of these
particular lubricators the cover has to be removed in both cases.
Fig. 4 may be taken as a section through a cover &c., having nuts, for adjusting
the feed spindle, brought to the outside, and further fitted with a "danger" signal;
whilst Fig. 5 forms a corresponding plan.
Fig. 6 shows in sectional elevation how an oil tube may, when required, be
arranged for filling the reservoir from the top of the cover.
The same letters refer to the same parts, or their equivalents, as far as possible,
in all the figures.
We accomplish our object as follows:-
The valve or stopper of the lubricator is directly or otherwise connected with an
electro-magnet in such a manner that when the circuit is completed the valve is
moved towards its open position by the attraction of the armature to the magnet;
and, on the contrary, when the current is broken the armature falls away and the
valve is again closed.
In Fig. 1 the armature A is attached to the valve spindle A' by nuts C¹ and C',
and, by the aid of these latter its distance from the poles of the magnet B, B, is so
regulated that the spindle, when lifted by the magnet, (as shown in Fig. 1), allows
the desired quantity of oil to pass forward. The cup is preferably of glass in order
to show the quantity of oil in reserve, and it may be filled through a tube fitted in
the top of the cover as shown in Fig. 6. A pin A, passed through the valve
spindle, and working in guides, keeps the armature (though free to rise and
fall) in one position, so that the cover, if taken off, and replaced in a previously
arranged position, determined preferably by a catch, may be in working line. The
armature however may be a disc, in which case an opening to the cup will, in small
sizes, require to be at the side, as at A' in Fig. 1; unless it is preferred to lift the
cover. A sufficient quantity of the exciting wire B1 and B2 must be left loose in
order to allow the removal of the cover B, the electro magnet being fixed therein
so that all may be lifted off together, which being done when the current is off,
leaves the armature and spindle behind in their proper place in the lubricator.
When in position the cover rests on the top of the cup as shown.
In Fig. 4 the armature A is shown indirectly attached to the valve spindle A'.
This spindle has a collar A' which supports a sleeve C, at whose head a lock nut, C³,
on the said spindle, presses. The sleeve has an enlarged head for regulating

page_text: purposes and its lower outer extremity is screwed through the armature A. By
these means, (without taking off the cover B³) by loosening the lock nut C, and
twisting the sleeve C, the armature A may be raised or lowered, and in that way the
amount of oil passed by the valve when the armature is attracted by the magnet
may be regulated. The armature, here shown out of action, has a bracket at A' which
prevents it from being twisted out of its place. In this example the top of the
cover B³ is dished to allow the cup to be filled from the top, as in Fig. 6.
The necessary electric current for exciting the magnets may be supplied by and
from any dynamo electric machinery, or from primary or secondary batteries.
When the current is laid on direct from a dynamo, or the like, it follows that
the lubricators are put in and out of action when the dynamo is started and
stopped.
Each lubricator may be made to display or set in motion a danger signal when
the armature is out of action, so that, when the attendant knows the exciting
current to be on, he may be warned by the said signal that something is wrong, if
standing at danger.
In Fig. 2, which corresponds with the internal adjusting nut arrangement (Fig. 1
C' and C), the danger signal is worked as follows:-
A spindle D, whose foot rests on a plate D' attached to the armature A, is
carried up until its head touches a lever D' whose fulcrum is at D³. At the outer
end of this lever-which of course gets an increased movement-a light cord
extends downward, and, after taking a turn or two round a roller D', ends in a
counterweight D' (or spring). The roller D, whose quarter diameter must be
proportional to the movement of the outer end of the lever, is mounted on a pin
riding in bearings attached to the cap B³. The bearings may be in plates between
which the danger signal may be hidden when drawn out of action. The signal D
is mounted on the roller and the cord is so wrapped that when the armature is out
of action, as in Fig. 2, the signal, marked on the drawing with the word "OFF,"
is fully displayed. By following this backwards it will be seen that when the
armature rises the lever also rises and the cord draws the signal down (out of
sight) and the counterweight up ready for action again as soon as the exciting
current next ceases.
In Fig. 4 the danger signal is worked on the same principle, but with the
following details :-Instead of having a special spindle D the valve spindle A is
prolonged until it reaches the lever D³. In Fig. 2 the fulcrum of the lever D* is
shown as an elastic spring hinge, whilst in Fig. 4 the end of the lever rests in a
socket, with a diminished end of the valve spindle A' passing through the lever D³,
which keeps it in position sideways. The exact mode of working this signal may
be varied to suit surrounding details.
When an entire factory is fitted throughout with our lubricators-the exciting
wires being run from one magnet to another—the whole of them may be started
and stopped by the starting and stopping of the engine producing the current; or
otherwise by the movement of a single switch.
In cases where it is desired to start the lubricators before the dynamo machinery
is put in motion, the current must be temporarily (or permanently) supplied from
batteries.
In many cases it is very desirable to supply oil to bearings before the machinery
is started, in which case a wire from a battery should be temporarily used for
first exciting the magnets; after which a wire from the dynamo machinery should
be relied on, as this pre-arranges the cutting off of the oil when the machinery
stops.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The mode of electrically controlling groups of lubricators, fitted with
magnets &c., by running an exciting wire, from a dynamo electric machine or

page_text: battery, forward from one magnet to another, and so acting on armatures attached
to the feed spindles, substantially as described and shown.
2. In an electrically controlled lubricator, having preferably a sight feed and a
visible reservoir, the combination of (1) an armature mounted on the feed spindle
and (2) an electro magnet, so placed that, along with the cover, it may be promptly
lifted and replaced, for the purpose of examination &c., substantially as described
and shown.
3. In an electrically controlled lubricator, having preferably a sight feed and a
visible reservoir, the combination of (1) an electro magnet with (2) an armature so
fitted to the feed spindle that its position thereon, in relationship to the magnet,
may be regulated, substantially as described and shown.
4. In an electrically controlled lubricator, having preferably a sight feed and a
visible reservoir, the combination of (1) an electro magnet, with (2) an armature
attached (indirectly) to the feed spindle in such a way that, whether in or out of
action, the height which the spindle lifts may be regulated, substantially as described
and shown.
5. In an electrically controlled lubricator, the combination of (1) the lubricator
itself, (2) an electro magnet and armature, and (3) mechanism for displaying a
"danger" signal, substantially as described and shown.
6. In an electrically controlled lubricator, the combination of (1) the lubricator
itself, (2) an electro magnet and armature, regulatable whilst in action, as to the
quantity of oil passing, and (3) mechanism for displaying a danger" signal-
substantially as described and shown.

7. An electrically controlled lubricator, arranged, constructed, and operated,
substantially as described and shown.
