COMPLETE SPECIFICATION.
Improvements in Oil-feeders.
I, CASPER MUELLER. of 100 State Street, Boston, in the County of Suffolk and
State of Massachusetts, United States of America, Inventor, do hereby declare the
nature of my invention for IMPROVEMENTS IN OIL-FEEDERS, 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 oil-feeders for engines, and has for its object to provide
an oil-feeder of novel construction, as will be hereinafter pointed out in the claims at
the end of this Specification.
Figure 1 is a vertical longitudinal section of an oil-feeder embodying my
invention;
Figure 2, a detail in side elevation of the lower portion of the feeder shown in
Fig. 1, looking toward the left in said figure;
Figure 3, a detail of the regulator, and
Figure 4 a sectional detail on line a x, Fig. 2.
The oil-receiving chamber or receptacle of the feeder is herein shown as a globe A,
preferably of glass. The globe A is provided with substantially diametrically-opposite
openings, normally closed by covers a a¹, the cover a' being herein shown as provided
with an annular groove a² in its upper face to receive an annular flange a³ on
the globe A. The cover a¹ has on its upper side an annular flange or tubular
extension a, provided, as herein shown, with screw-threads on its inner and outer
sides. The tubular extension a¹ is engaged on its inner side with a sleeve or tube a³
extended up through the opening in the top of the globe A and outside of the said
globe. The said sleeve or tube has screwed into it a hollow regulating-plug b,
having its lower portion made plain and provided with a cam-shaped slot b¹, provided,
as herein shown, at its highest point (see Fig. 3) with a notch 62, adapted to receive
a pin or projection 63 on a spindle & extended through the hollow plug 6 and sleeve a,
the said spindle preferably having its lower end made conical or pointed to fit a
conically-shaped seat and close the outlet opening for the globe A, the said opening
being preferably formed in an independent nozzle & secured to the underside of the
cover a. The spindle below the end of the hollow plug is encircled by a spiral
spring 7, one end of which abuts against the said hollow plug and the other end
against a pin 8 extended through the spindle, but it may be a collar on said spindle.
The spring acts to force the spindle down toward its seat at all times.
outlet-nozzle for the globe A is extended into a chamber , having two of its
opposite sides preferably cast integral with the cover a', and with a discharge-
nozzle forming the bottom of the chamber e. The two opposite sides of the
chamber c are made of glass or other transparent material, the said sides forming
sight-windows c³, which are removable, but are normally locked in place by the thumb-
screw, pivoted on one side of the chamber c, and having arms which lap over or
extend beyond the edge of the said side and fasten the removable windows in place.
the rear edge of the said windows abutting agaiust the projecting edges c* of the
The

page_text: opposite side, as clearly shown in Fig. 4.
The windows c³ may be readily removed
by turning the thumb-screw substantially at right angles to the position shown in
Fig. 4. The hollow tube a' is provided with suitable feed-holes 2, through which
oil in the globe may pass into the said tube. The hollow plug constitutes a regulator
to determine the quantity of oil to be fed to the bearing to be oiled, and this plug
in practice will be screwed down into the tube a more or less, and will be fastened
in adjusted position by a set-screw 3. The further the said plug is screwed down the
less the feed. When the feed is to be stopped altogether, the spindle will be turned
in a direction to permit it to descend under the action of spring and close the
outlet, as in Fig. 1.
To enable a stream of oil to be fed, lift the spindle and rotate it partially until the
pin enters the notch 12, as in Fig. 3, and a sufficient quantity of oil having been
discharged, the spindle will be further turned to place the pin ³ in the regular
feed-notch 4, (herein shown as the end of the groove 61 at the left in Fig. 3,) the
spindle in this last position permitting the oil to be delivered in regulated
quantity.
The sight-windows may be easily removed to be cleaned by turning the thumb-
screw.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In an oil-feeder, the globe, the covers a a', the delivery-tube 66, the tube a³, the
spindle having a pin 3 and a spring to normally depress the said spindle, combined
with the hollow regulating-plug, having a cam-slot entered by the said pin, the said
cam-slot having two notches to he entered by the said pin, one notch to insure the
discharge of oil in regulated quantity and the other to enable a stream to be discharged,
substantially as described.
2. In an oil-feeder, the chamber c, having open sides and sight-windows c³ to
close the same, combined with the thumb-screw c³, having arms to overlap the edges
of and keep the sight-windows in place, the said windows abutting against the pro-
jecting edges of the opposite side, substantially as described.
Dated this 18th day of October 1890.
