Improvements in Automatic Oil-pumps.
I, CHARLES WILLIAM MANZEL, of 87, Van Rensselaer Street, in the City of Buffalo,
County of Erie, State of New York, United States of America, Mechanic, 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:-
My invention relates to an improved automatic oil-pump, and the principle
objects are to provide a simple and practically noiseless feeding device and a
simple and convenient means for regulating the feed.
It also relates to certain details in construction of the oil-pump and its opera-
ting mechanism, all of which will be fully and clearly hereinafter described and
claimed, reference being had to the accompanying drawings, in which:-
Fig. 1 represents a side elevation, partly in section, of my preferred embodiment
of the oil-pump complete.
Fig. 2 represents an edge view of the flanged disk and its annular grooved ring
and the operating clutch mechanism.
Fig. 3 represents a top view of the operating clutch mechanism, partly in
section.
Fig. 4, represents a detached side elevation of the annular internally grooved
ring and its operating clutch.
In referring to the drawings in detail, like numerals represent like parts.
1 represents the frame which is of the usual iron construction and is provided
at one end with an upright 2, having boxes 3, in which the forward end of the
plunger shaft 4, is supported.
The oil-cup 5, is preferably supported at the opposite end of the frame, and
is provided with an outlet tube 6, having an opening 7, through which the oil
flows and a feed regulating device, which will be specifically described further on.
The plunger 4, is provided with a cam 8, having a slot 9, in which the crank
pin 10, of the rotating disk 11, is adapted to travel.
To lessen the friction, the crank pin is provided with a loosely encircling
annular ring 12.
The device is also provided with a brake mechanism comprising a curved brake
spoon 13, having the interior lugs 14, and the leather portion 15.
This brake spoon is preferably secured to the upright 2, by a screw or bolt 16,
thus allowing a range of pivotal movement sufficient to allow it to enter into or
withdraw from frictional contact with the periphery of the disk 11.
The crank disk 11, is rigidly mounted upon a shaft 17, which is supported in
boxes upon the frame, and a second disk 18, is also rigidly mounted upon the
shaft 17, which is provided with a laterally extending circular flange forming
an annular ring 19, the interior of which is provided with a groove 20, prefer-
ably V shaped in cross section in which the clutch block 21, is adapted to travel.
The clutch block 21, is actuated by a vibrating arm 22, which is loosely hung at
one end from the shaft 17, so as to move freely thereon.
It is provided with a longitudinal slot 23, and a connecting rod 24, is pivoted

page_text: at one end to the clutch block by means of the screw or bolt 25, and a screw
bolt 26, is passed through the opposite end and through the slot 23, see Fig. 4.
By referring to Fig. 4, it will be seen that a movement of the vibratile arm in
one direction will cause the clutch block to frictionally engage with or grip against
the interior of the groove 20, thus rotating the disk 18, and the shaft 17, and that
a movement in the opposite or reverse direction will move the clutch block with-
out rotating the disk.
The direction of the rotation of the shaft can be changed by moving the clutch
block to the opposite side of the vibratile arm, and the tension of the grip of the
clutch block upon the interior of the grooved annular ring can be regulated to a
certain degree by varying the angle of inclination from the centre by moving
the bolt 26, in the slot 23.
By means of the annular grooved ring and the clutch mechanism, the recipro-
cating movement of the vibratile arm is converted into an intermittant rotary
movement of the shaft and that is in turn converted into a reciprocating move-
ment of the plunger by means of the slotted cam and crank disk.
The shaft can be rotated by hand if desired, by fitting a crank or similar tool
upon the square end 27.
The feed regulating device comprises the substantially vertical tube 6, which
passes centrally through the oil cup 5, and is provided near its lower end with
openings 7, for the admittance of oil.
The lower end of the tube 6, communicates with a substantially horizontal
feed tube 28, in which the plunger 4, operates, the said tube having a valve 29,.
and stop cock 30, at its forward end.
A screw bar 31, within the tube G, is raised or lowered by rotation to cause
its lower end to close the opening 39, to a greater or lesser degree and thereby
regulate the flow of the oil.
This bar 31, is provided with an enlarged upper end 32, and a lock nut 33, for
locking it in any position to which it may be adjusted.
To test the flow, a tube 34, projects substantially vertically upward from near
the forward end of the feed tube 28, with its upper end bent upon itself and a
small cage of closely woven wire netting is suspended from the cover and the
end of the tube 34, is arranged to direct the oil into the same.
This tube 34, is also provided with a stop cock 35.
The operation of the device is as follows,-
The vibratile arm being started, the plunger is reciprocated and the oil fed,
the amount of oil being regulated by the regulating device and the same judged
by the testing device, the oil passing from the cup through the opening in the
vertical tube 6, into and through the tube 28, and thence into and through the
testing tube 34, and again into the cup.

When the feed is regulated to the desired point, the stop cock 35, controlling
the flow of oil through the tube 34, is shut off and the stop cock 30, is opened,
thereby permitting the oil to be fed to the machinery it is desired to lubricate.
A glass tube 36, of suitable diameter is arranged below the opening 7, being
mounted in the vertical tubular cup supporting portion 37, thereby providing
a visible feeding device, the drops of oil as they descend being observed through
the tube 36, substantially as shown in Fig. 1.
By this means the rapidity of the feed can be easily discerned and regulated.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. A device for converting a reciprocating movement into an intermittant
rotary movement, comprising an internally grooved annular ring rigidly mounted
upon a shaft, a reciprocating arm loosely suspended from the same shaft and having
a longitudinal slot, a clutch block adapted to fit and travel in the groove in the
ring, a rod pivotally connected at one end to the clutch block and a bolt passed

page_text: through the opposite end of the rod and the longitudinal slot in the arm, as set
forth.
2. In an oil pump the combination of the supporting frame, a cup mounted
upon said frame and having a valve and a plunger device, a slotted cam rigidly
secured to the plunger, a shaft mounted in boxes in said frame, a crank disk
rigidly mounted upon said shaft and having a crank pin adapted to travel in
the slot in the cam, a second disk also rigidly mounted upon said shaft and having
a laterally extending flange having an interior groove, a clutch block adapted
to travel in said groove, a reciprocating arm swinging loosely from said shaft
and having a longitudinal slot, and a connecting rod pivotally fastened at one
end to the clutch block and provided at the opposite end with a bolt adapted to
be inserted and secured in the slot in the reciprocating arm, as set forth.
