Improvements in Automatio Lubricators for Machinery.
We, FERDINAND THIEL Carrier and JULIUS THIEL Machine Minder both
of Mittelwalde, Germany, and CARL GEIER, of Oberlaugenbielau, Kreis-
Reichenbach i/Schlesien Germany Machine Minder, 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 certain improvements, hereinafter pointed out in the
claims, in lubricators for lubricating the bearings and bushes of machinery. By
means of the improved lubricator such bearings and bushes can be automatically
and continuously lubricated.
And in order that our said invention can be properly understood we have
hereunto appended an explanatory sheet of drawings, whereon,
Fig. 1, is a vertical section, showing part in elevation, of the automatic.
lubricator.
Fig. 2 is an end view of the same.
Above the bearings of the shaft A requiring to be oiled, is a receptacle a made
of strong sheet zinc the lid or cover of which is provided with an opening c
through which the receptacle is supplied with oil. Passed through slots or
openings d at each end of the receptacle is a strong and not springy wire e.
The part of this wire within the receptacle is made with two loops or holes f
through which are passed screw bolts fl each provided with a hook at its lower end
and a butterfly nut, for adjustment, at its upper end. Attached to each of these
bolts is a lead plug or piston which is enclosed in a wire seive g and whose lower
end enters the funnel shaped upper end of a pipe h¹ and can be adjusted therein,
as desired. One of the ends of the wire e, as shown, is bent into the form of a
square i and this squared part bears against au eccentric (or an iron ring made
with a projection on it) secured to the shaft A. As the shaft revolves, the
result of this oscillation of the
eccentric causes the wire e to oscillate, and, as
which
wire e, the pistons are moved up and down and thereby alternately open and
shut the passage ways leading to the pipes ' so that the lubricant is caused to
drip regularly and in uniform quantities into the pipes h' and so to the bearings.
An automatic low level alarm mechanism is also provided. This mechanism
consists of metal ball floats I, 1, hung by thin wires which pass through guide
tubes m in the lid and are made one with or connected to a cross wire

low, is caused to strike against bell by means of the end k of the oscillating
wire e. This end is, as shown, bent to a tapering or V shape and serves as a guide
for the wire . The horizontal part of the wire passes between upwardly
projecting spring arms m¹.
When the oil is at the top of the receptacle, as shown in dotted lines, the
parts of the alarm mechanism are also in the position indicated in dotted lines so
that the oscillations of the guide k and wire with the head n do not affect the bell
as the head n is far above it. When, however, the oil sinks to the level shown in
full lines then the wire is lowered in the same degree so that, at each oscillation
3 of the guide k, the head n strikes the bell k' and sounds a continuous alarm.

page_text: 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
consider novel and desire to claim is :-
1. An automatic lubricator for machinery characterized by one or more plugs or
pistone (h) fitted in an oil reservoir (a) and alternately raised and lowered so as
to open and close the passage ways leading to the pipes by means of a wire (e),
or its equivalent, oscillated by an eccentric on the shaft to be oiled, substantially as
hereinbefore described and shown on the drawings annexed.
2. The combination with the lubricator claimed in Claim 1, of the automatic
alarm mechanism, consisting of one or more floats arranged in the oil receptacle a
and connected by wires, P, or their equivalent, to the striker n of the bell,
substantially as herein before described with reference to the drawings annexed.
Dated this 20th day of April 1896.
