IMPROVEMENTS IN MECHANICAL OILERS FOR JOURNAL BEARINGS
Year: 1885

page_text: 1, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of my invention for IMPROVEMENTS IN
MECHANICAL OILERS FOR JOURNAL BEARINGS, a communication to me from abroad
by Henry Pennell Humphrey, of 37, Nineteenth Street, Lowell, Massachusetts, one
of the United States of America, Machinist, 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,-First, in means hereinafter described for supplying a
uniform quantity of oil to a journal bearing.
Secondly, in means hereinafter described, of regulating the quantity of oil
supplied to such bearings.
Thirdly, in means hereinafter described of catching the oil which overflows
from the journal box, and returning the same to a reservoir connected with
said box.
Fourthly, in means hereinafter described of securing the mechanical oiler or
pump to said box.
The improvements are shown in the accompanying drawings, in which, Fig 1 is a
front elevation of a journal box with an oil pump attached thereto; Fig 2, an end
view of the same; Fig 3, a plan of the same; Fig 4, a vertical cross section of the
journal box without the pump on the line xx in Fig 5; Fig 5, a central
longitudinal section of the journal box without the pump; Fig 6, an isometric
view of the piston and a part of the piston rod; Fig 7, a vertical central section of
the pump.
A is a horizontal shaft. The box B is intended to be, ordinarily, of cast iron
and is provided with an oil-hole b¹ in the top thereof, and is further provided, on
each side, with a ledge C which descends from a point at about the height of the
top of the shaft and midway between the ends of the box proper b towards the
ends of said box and is grooved, at c on its upper surface, as shown in Figs 2 and 4,
to form channels to catch the oil overflowing from the hole 6. Each end of the
box is provided with a drip-receiver D D¹, to catch and retain the oil which drips
from the shaft at the ends of the box proper and also to receive the oil dripping
from the ends of the grooves c,-said grooves leading into the drip receivers. The
box is also provided with a reservoir E, preferably, cast in one piece with said box
ID 37

page_text: proper and placed beneath one of the receivers D which opens into said reservoir.
A passage is cored out in the lower part of the box to connect the receivers D Dt
to each other and to the reservoir E. The reservoir serves as a well to hold the oil
and to receive the oil pump K.
The oil pump K may be of any suitable construction (having means whereby the
piston is thrown down automatically, after being lifted to discharge the contents of
the pump, and let go), but I prefer to use a pump of the construction herein shown
and described, by which the oil is expelled from its nose or spout k on the up-stroke
and the piston is then forced downward by a spiral spring, surrounding the
piston-rod between the piston and the closed top of the pump. In Figs 6 and 7,
K¹ denotes the cylindrical pump-barrel; ¹, the piston-rod; k³, the closed head or
stuffing box (of ordinary construction); ³, a spiral spring surrounding the piston-
rod below the head 7º, and compressed between said head and a collar / on said
rod; ³, the piston; k, a valve in the piston which rises as the piston is forced
down by the expansion of the spring and allows the oil to pass up through the
central orifice a of said piston and up through the passages e in said piston, said
valve being a conical metallic plug rising and falling in the cylindrical orifice k²,
the top of which is closed by a flange or enlarged head of the same resting upon
the top of said orifice 7, the head of said plug or valve being prevented from rising
entirely out of said orifice by the lower end of the piston-rod as shown. The
lower valve-box 10 of said pump is similar in construction and has a similar valve
or conical plug 11 which is prevented from rising out of said valve-box by the
strap secured across the top of the same above said last named valve. The
construction of the pump not being claimed herein, no further description thereof
is necessary, its operation being evident from the drawings.
A bracket G is fastened to the back side of the reservoir E by screws g g and is
provided with two horizontal forked projections I I', one I above the other I', in
the forks of which the pump K. rests, being held in said forks in a vertical position
by a U-shaped strap L which embraces the barrel of the pump between the
forks, the ends of the strap L passing through said bracket and being held by
nuts screwed on said ends which are threaded therefor. The nose k of the
pump extends over and discharges into the oil-hole b¹. The upper end of the
piston-rod k is provided with an eye or loop k², into which loop hooks one end of
the lever M.
A bracket P is secured to the pump by its clamp p p. The bracket P is provided
with a vertical hole, just large enough to receive the pump barrel, below its head,
and is slotted from said hole to the end of said ratchet, to form jaws p pl
which are drawn together to clasp the pump barrel by the screw p7 which passes
through one jaw p₁ and screws into the other p, the screw being provided with
enlarged head p³.
The bracket P is provided with an upward projection which is notched on the
top, to receive the lever M and serves as a fulcrum therefor. The bracket P is also
provided with two nearly horizontal projecting arms R S, in the upper R of which
is secured a vertical stud T, which reaches up through the slot in the lever M and
is screw-threaded above the same to enter a nut t and check-nut t¹. By moving
the nut and check-nuts on said stud T the length of the stroke of the piston k¹ may
be increased or diminished, evidently, and the amount of the oil fed to the bearing
at each stroke be thereby regulated.
There is another rod V which passes through a slot in the lever M and also
through the two arms R. S. The upper end of said rod V is provided with a head
or enlargement, or with a screw-thread on which turns a nut W, the object being
to prevent the rod from drawing out of the lever M. The lower end of the rod V
is screw-threaded and carries two washers v vl, one of which the lower v¹ is of sheet
metal and the other of which is of leather or raw-hide. The washers are for a
cam or wiper H, secured on the shaft, to strike upon, as the shaft revolves to raise
the piston of the pump by rocking the lever M and thereby to discharge oil through
the spout k, and washers are used, rather than an arm projecting from said rod V, in

page_text: order that, however the rod may be turned, the cam may always draw down said
rod by each revolution of the shaft. The upper washer v is made of raw-hide to
deaden the sound made by the wiper striking it and to lessen wear of the parts.
The washers are held in place by nuts on said rod V, one v³ above and the other v³
below said washer.
In order that the rod V may come back to its place after being thrown upward
by the wiper when the motion of the shaft is reversed, there is a spiral spring v
surrounding the rod, between the lower arm S and the nut v², and this spring v*
presses the rod V downward in the arms R S which serve as guides therefor.
It will be seen that the box B may be used without the oiler, in which case, the
reservoir will serve the purpose of an ordinary drip-pan, with this difference and
advantage that the pan and box will be in one piece and may be supported in a
hanger instead of being beneath the hanger, as usual. When the box is used,
with or without the oiler, it may be provided with a discharge-cock for emptying
the same.
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. The combination of an oil pump, a lever, a rod connected to said lever, means
of supporting the same, washers on the end of said rod and a wiper and means of
rotating the same, as and for the purpose specified.
2. The pump and means substantially as described, of operating the same in
combination with means of regulating the length of the stroke of said pump, as
and for the purpose specified.
3. The combination of the pump, the lever connected at one end with the piston-
rod of said pump, a rod connected at the other end of said lever by the upper end
of said rod, the lower end of said rod being provided with a screw-thread, washers
surrounding the threaded end of said rod and nuts turning on said rod above and
below said washers, as and for the purpose specified.
4. A journal box provided with an oil-hole, with overflow-channels, one or more
end-drip receivers, an oil reservoir and an oil passage, connecting said drip receivers
with the oil reservoir, as and for the purpose specified.
5. The combination of the journal box, having an oil reservoir, a mechanical
oiler, and means substantially as described, of securing said oiler to said box, as and

purpose specified.
7. The combination of the journal box, having an oil reservoir and a mechanical
oiler, the bracket provided with forked bearings, the U-shaped strap and nuts, as
and for the purpose specified.
8. The combination of the pump, the bracket, having a hole to admit said pump
and having a slot, leading from said hole to the end of said brackets, and a screw,
said bracket having projecting guides and a projecting fulcrum and the lever,
turning on said fulcrum, as and for the purpose specified.
