PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Lubricating Bearings, and in
Apparatus for Automatically Indicating when the Lubricant
Fails.
:—
We, WILLIAM ARNOLD, of No. 3, Anvil Street, Brighouse, Yorkshire,
Engineer, and WILLIAM CROWTHER, of Broadholme Mill, Brighouse, aforesaid,
Cotton Spinner, do hereby declare the nature of this invention to be as follows:-
This invention consists in constructing and arranging a new form of apparatus
for lubricating the bearings of revolving shafts or reciprocating parts of
machinery.
The invention also consists in the application thereto of an electric magnet for
setting into motion indicators when the supply of lubricant fails through defective
pumps, the breaking of driving bands or cords or from other causes.
In carrying out our invention we adopt a suitable form of oil cup having an
outlet in communication with the bearing or other part requiring to be lubricated.
This oil cup is provided with a suitable form of valve for regulating the quantity
of lubricant to pass from the said oil cup. This cup is connected to a pivoted
lever or rod provided with a balance weight and the oil to supply the cup drops
into the same, and when full overcomes the power of the balance weight, but
should the supply of oil fail the cup becomes lighter, consequently the pivoted lever
is made to tilt by the balance weight, in doing which it comes into contact with a
switch causing a complete electric circuit to be established whereby a magnet
attracts a lever from holding a weighted disc, such disc oscillating upon its
fulcrum taking with it a signal board which denotes to the attendant that the
supply of lubricant has failed. An eccentric is attached to or formed on the disc
so that when the magnet has lifted the holding catch from the disc and operated
the signal, the eccentric which previously was bearing on a switch is now made to
leave the said switch so as to shut off the electric current, thus preventing the
battery from running down which otherwise would happen.
Instead of employing an eccentric for shutting off the electricity a spring may be
employed.
Instead of employing a signal to arouse the attention of the attendant an electric
bell may be used or they may be used in conjunction.
Instead of using a balance weight for completing the electric circuit, a spring or
float would answer the same purpose. The electric parts of the apparatus,
together with the signal may be situated in the engine house of a factory or in the
offices connected therewith. When the attendant has resumed the supply of
lubricant the signal disc is pulled by a cord or other means so as to put a catch in
gear with the lever, this movement causing the eccentric to come into contact with
the switch. One or more balanced oil cups may be used in connection with one
signal or a signal for each cup.

page_text: Improvements in Apparatus for Lubricating Bearings, and in
Apparatus for Automatically Indicating when the Lubricant
Fails.
We, WILLIAM ARNOLD, of No. 3, Anvil Street, Brighouse, Yorkshire,
Engineer, and WILLIAM CROWTHER, of Broadholine Mill; Brighouse, aforesaid,
Cotton Spinner, 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 constructing and arranging a new form of apparatus
for lubricating the bearings of revolving shafts or reciprocating parts of
machinery. The invention also consists in the application thereto of an electric
magnet for setting into motion indicators when the supply of lubricant fails
through defective pumps, the breaking of driving bands or cords or from other
causes.
In order that our invention may be more fully understood reference is herein
made to the annexed sheet of drawings illustrative thereof, wherein Fig. 1 is
elevation of an oil cup, and an electric signalling apparatus arranged according to
our invention. Figs. 2, 3 and 4 are details of parts hereinafter referred to.
In the drawings, A indicates the oil cup to which oil is supplied in any ordinary
manner from a pipe or vessel situated above it and not shewn. The said cup is
secured to one end of a lever or arm B, pivoted at C to the pedestal or bracket D,
and is counterbalanced by a weight secured on the opposite end of the said
lever. Insulated from the bracket D is a contact maker or switch a which is
electrically connected by line wire through binding screw c on the signalling
board F to the screw d to which is attached a switch or contact maker e engaging
normally with an eccentric cast or otherwise formed on the back of a disc g. The
said disc g is mounted on a study and has fastened thereto, a signal board or
semaphore whose weight is sufficient to cause the disc to rotate in the direction
of the arrow when released by the lever i which is normally in engagement with the
catch of the eccentric f
The disc g and eccentric are connected by wire to one pole of the electric
magnets G and the opposite pole is connected with the binding screw c¹.
y
.
The release of the lever i from catch is effected in the following manner:
When there is a full supply of oil in the cup A counterbalance weight E is
overcome and the lever assumes the inclined position shewn in full line in Fig. 1
and is clear of the switch a, but, on the supply of oil ceasing from any cause, the
cup becomes empty and therefore lighter consequently lever B assumes the position
indicated in dotted lines, bringing the recessed portion on the underside of lever B
into contact with the switch a, whereby the electric circuit is completed, causing
the magnets G to attract the lever i and place it clear of the catch on the
eccentric as indicated in dotted lines, whereupon the disc is made to rotate in
the direction of the arrow by the weight of the signal board or semaphore h, placing.
the red or coloured half of the latter opposite a sight hole in the cover (not shewn)
which encloses such signalling apparatus, thereby indicating to the attendant that
the oil supply to the oil cup has failed. A stop picce may be secured to the
board F when there is no bell circuit, for the purpose of limiting the motion of
the parts, and they are re-instated in the position shewn in the drawings by pulling
down the cord which passes over and is secured to a boss or pulley at the back of
the disc 9. When the disc g is released and rotated as above set forth, the contact
between it and the switch or contact maker e is broken by reason of the eccentric /
which is moved clear of the said contact maker e and breaks the circuit whereby no
waste takes place.

page_text: To give audible warning of the failure of the oil supply in addition to and in
conjunction with the signal above described if so desired, we add a bell circuit to
the apparatus.
On the periphery of the disc y we fix a pin or finger m (shewn more clearly in
Fig. 2) which, when the disc is released and rotated, is brought into contact with
the insulated end of a spring contact maker n which is thereby pressed down onto
the adjustable screw o, the circuit being thus completed and the bell H set ringing,
either continuously or intermittently until oil is again supplied to the oil cup.
The intermittent, instead of constant ringing of the bell, is effected by a contact
maker on a reciprocatory or rotary part of the engine or machine which makes and
breaks contact at every stroke or revolution.
The oil supplied to the cup A passes through openings or slots p in the pipe y,
then through similar openings pl in the pipe r which fits into said pipe g as shewn
in section at Fig. 4, and from thence the oil passes down said pipe 9 and falls into
a shallow cup shaving communication with the bearing or part to be lubricated
and secured in the pedestal or bracket D.
By turning round the piper the holes or openings p¹ therein can be fully or
partially exposed to the openings and the supply of lubricant to the bearing or
other-part be thus regulated to suit requirements.
P
Figs. 2 and 3 are enlarged front and side elevations respectively of the disc and
eccentric.
A stop piece (see Fig. 3) secured to the board F is provided to prevent the
lever i descending too far when the circuit is broken by the eccentric moving clear
of the contact maker e.
Although we have shewn a bell circuit in conjunction with the apparatus for
giving a signal on the failure of the supply of oil, it will be understood that such
apparatus may be arranged and constructed without a bell circuit.
Instead of using a balance weight F for completing the electric circuit, a spring
or float would answer the same purpose.
The electric parts of the apparatus, together with the signal may be situated in
the engine house of a factory or in the offices connected therewith. One or more
balanced oil cups may be used in connection with one signal or a signal for
each cup.
Having now particularly described and ascertained the nature of our said inven-
Lion and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. For lubricating revolving or moving metal surfaces, the employment
of a balanced oil cup, in combination with a suitable arrangement of electric
switches and battery, all arranged and operated substantially as described and
shewn in the accompanying drawings.
Secondly. For lubricating revolving or moving metal surfaces, the use of a
balanced oil cup and electric appliances, in combination with a signal board such
ash, all arranged and operated in the manner substantially as shewn and described
herein.
Thirdly. For lubricating revolving or moving metal surfaces, the use of a
balanced oil cup, in combination with means for regulating the quantity of oil
passing from the said oil cup, all as herein shewn and described.
