EDWIN AMBROSE BRYDGES of the firm of Brydges & Co, Engineers and Patent
Solicitors of 107 Königgrätzer Str in the city of Berlin and German Empire and
of 6 St Leonards Terrace Upton in the County of Middlesex IMPROVEMENTS IN
AUTOMATIC LUBRICATING APPARATUS AND LUBRICATING SQUIRTS OR SYRINGES,
a
communication to me from Friedrich Tovote of the city of Hanover in the German
Empire.
This invention relates to improvements in automatic lubricating apparatus,
whereby a lubricating material of considerable consistence is employed; and also
to lubricating squirts, syringes or devices for injecting the lubricating material on
to the parts to be lubricated.
These lubricating apparatus or devices are specially adapted for lubricating
plumber blocks, shafting, pedestals, loose drums or pullies and all small machine
parts where thick lubricants can be employed.
In one arrangement of my automatic lubricating apparatus or device for
lubricating shafting brackets a hollow piston provided with a hollow spindle is
employed, which said spindle is guided in the lid of the receptacle so as to regulate
the consumption of consistent fat or grease or other lubricant, whereby the
hollow piston is filled or partially filled with shot, pieces of lead or other suitable
material.
In order that the piston may be accurately guided in the aforenamed receptacle,
the same is provided with a suitable leather collar.

page_text: By means of the pressure of the weighted piston on the lubricating material and
the movement of the shafting, the lubricant is forced through the conical tube on
to the surface to be lubricated.
The hollow piston spindle is closed by means of a hollow cap or cover the
rim or flange of which is painted with luminous paint and serves as an optical
signal disc.
As soon as the receptacle becomes empty the disc shuts down on to the lid and
the luminous side of the disc is no longer to be seen.
In a modification of this device I arrange hinges on the lid for carrying the
aforesaid signal disc.
This said disc is regulated in such a manner by means of a weight, that when
the grease is so far expended as to admit of the pin of the signal disc coming in
contact with the cover, the said dise loses its balance and takes either a vertical or
horizontal position as desired.
The surface of the disc can also be painted with luminous paint or a bright color
in order to render the same more distinct. In this arrangement an electric wire
can be conducted past the lubricating apparatus so that when the cover tips up
contact is established, in consequence of which an electric signal can be given at
any desired place indicating that one of the lubricating apparatus has become
empty.

receptacle consists of two parts which are screwed together; a hollow piston pro-
vided with a hollow spindle slides tightly up and down in the lower part of the
aforementioned grease receptacle.
This said piston can be weighted according to requirements; and in order to
attain a proper compensation a spiral spring may be arranged underneath the
piston.
The upper part is provided with hinges in order to carry the signal disc. This
latter is arranged on its pin in such a manner that it is always inclined to occupy
a vertical position and is only held in horizontal position by means of a suitable
catch.
This lubricating apparatus is screwed into the boss or hub of the pullies in a
radial direction.
The method of action is a follows:
The piston which can move freely in the receptacle presses in consequence of the
centrifugal force occasioned by the revolutions of the pulley, the grease on to
the part to be lubricated.
When the receptacle becomes empty, the piston presses against a pin which
occupies a position underneath the aforementioned catch to the signal disc, and
this causes the said catch to release the signal disc, and the same of course springs
into a vertical position, when its bright colored or luminous surface announces
that fresh filling is required.
The arrangement of a grease syringe or squirt is as follows.
The cylindrical grease receptacle is closed at the top by means of a suitable
cover and in the bottom part of this said receptacle the piston slides up and down.
The spindle of this said piston is hollow and tapers off to a point.
In using this syringe the point of the same is inserted into the lubricating hole
and by pressing down the cylindrical receptacle the grease which is situated above
the before mentioned piston is caused to flow on to the part to be lubricated.
It is evident that the method of arranging the catch for the signal disc and also
the manner of coloring the same may be altered without departing from the tenor
of my invention.

AUTOMATIC LUBRICATING APPARATUS AND LUBRICATING SQUIRTS OR SYRINGES A
communication to me from Friederick Tovote of the City of Hanover in the German
Empire
This Invention relates to improvements in automatic lubricating apparatus
whereby a lubricating material of considerable consistance is employed, and also
to lubricating squirts, syringes, or devices for injecting the lubricating material on
to the parts to be lubricated
These lubricating apparatus or devices are specially adapted for lubricating
plumber blocks, shafting, pedestals, loose drums or pullies and all small machine
parts where thick lubricants can be employed.
In one arrangement of my automatic lubricating apparatus or device for lubri
cating shafting brackets as shewn in the Figures 1, 2 and 3 a hollow piston d
provided with a hollow spindle is employed which said spindle is guided in the
lide of the receptacle a so as to regulate the consumption of consistent fat or grease
or other lubricant, whereby the hollow piston d is filled or partially filled with
shot, pieces of lead or other suitable material.
In order that the piston inay be accurately guided in the aforenamed receptacle a
the same is provided with a suitable leather collar.
By means of the pressure of the weighted piston on the lubricating material and
the movement of the shafting, the lubricant is forced through the conical tube b on
to the surface to be lubricated.
The hollow piston spindle is closed by means of a hollow cap or cover the rim
or flange of which is painted with luminous paint and serves as an optical signal
disc
As soon as the receptacle a becomes empty the disc shuts down on to the lid e
and the luminous side of the disc is no longer to be seen.
In a modification of this device as shewn in Figures 2 and 3 I arrange hinges f
on the lid for carrying the aforesaid signal disc h.
This said disc is regulated in such a manner by means of a weight that
when the grease is so far expended as to admit of the pin g of the signal disc h
coming in contact with the cover, the said dise loses its balance and takes either a
vertical position Figure 2 or a horizontal position Figure 3 as desired.
The surface of the disc can also be painted with luminous paint or a bright
color in order to render the same more distinct-In this arrangement an electric
wire can be conducted past the lubricating apparatus so that when the cover tips
up contact is established, in consequence of which an electric signal can be given
at any desired place indicating that one of the lubricating apparatus has become
empty.
For loose pullies or drums the lubricating apparatus as shewn in Figure 4
is arranged as follows-The receptacle consists of two parts a, b, which are
serewed together; a hollow piston d provided with a
hollow spindle c
slides tightly up and down in the lower part of the aforementioned grease
receptacle
The said piston d can be weighted according to requirements and in order to
attain a proper compensation a spiral spring may be arranged underneath the
piston

page_text: The upper parte is provided with hinges in order to carry the signal disc h.
This latter is arranged on its pin f. in such a manner that it is always inclined to
occupy a vertical position and is only held in horizontal position by means of a
suitable catch l.
This lubricating apparatus is screwed into the boss or hub of the pullies in a
radial direction
The method of action is as follows:-
The piston & which can move freely in the receptacle presses in consequence of
the centrifugal force occasioned by the revolutions of the pully, the grease on to
the part to be lubricated.
When the receptacle becomes empty, the piston d presses against a pin m which
occupies a position underneath the aforementioned catch to the signal disc and
this causes the said catch to release the signal disc and the same of course
springs into a vertical position when its bright colored or luminous surface
announces that fresh filling is required.
The arrangement of a grease syringe or squirt as shewn in Figure 5 as
follows-
The cylindrical grease receptacle a is closed at the top by means of a suitable
cover band in the bottom part f of this said receptacle the piston d slides up and
down. The spindle of this said piston is hollow and tapers off to a point e.
In using this syringe the point e of the same is inserted into the lubricating hole
and by pressing down the cylindrical receptacle the grease which is situated above
the before mentioned piston is caused to flow on to the part to be lubricated as
shown by the arrow Figure 5.
It is evident that the method of arranging the catch for the signal disc and also
the manner of coloring the same may be altered without departing from the tenor
of my Invention.
Having now described my said Invention and the manner in which the same is
to or may be carried into effect I desire it to be understood that what I claim and
desire to secure by Letters Patont is :-
1. The arrangement and employment of the piston d provided with hollow
shaft or rod c which said piston is filled or partially filled with lead or other ballast
material and which said piston rod is provided at the upper part with a signal
plate or disc and the lower surface of the piston provided with a ring or collar
in such manner that the consistent fat is automatically fed to the parts to be
lubricated substantially as described in the foregoing specification and shewn in
the accompanying drawings.
