Improvements in Lubricating Apparatus.
I JOHN ARMYTAGE BATLEY of 1 Elvaston Place, Queen's Gate in the County of
Middlesex, Barrister-at-Law, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide crank pins and journals of shafts with an
automatic supply of oil or other lubricant, the supply being regulated by the speed of
rotation of the parts to be lubricated, and the surplus being returned to a reservoir
ready to be circulated through the lubricating apparatus.
it
The plummer block used for shafts is formed with a reservoir below the lower brass
or bearing for the journal, and from the opposite sides of this reservoir, rise passages
leading upwards to, and above the top brass or bearing. Secured to the shaft to be
lubricated, is a wheel or disc, which is enclosed in one of the passages of the plummer
block, and dips into the lubricant in the reservoir. The periphery of this wheel or
dise may be flat or otherwise shaped, but preferably it is rebated to form, by its two
diameters, a right angle in which the lubricant collects. A scraper of peculiar
construction rests loosely on the top of this disc or wheel, and is held down upon
by a pressure spring, to which it is attached, and which is fixed, to the cap of the
plummer block. This scraper, when it is intended to act upon a lubricating disc or
wheel, the direction of rotation of whose shaft will occasionally vary, is made double,
its two ends embracing the disc or wheel.-A passage in the scraper leading from its
point of contact with the periphery of the disc or wheel, conducts away the lubricant,
and delivers it in a stream into a chamber in the cap above the top brass, which
chamber is cast with a raised lip for retaining a supply of lubricant.-Holes are made
through the cap and top brass to allow the lubricant to run down to the journal and
maintain the requisite supply thereto.
In case of a slight oscillation of the shaft carrying the disc or wheel, the scraper
will be free to follow the lateral movements of the disc or wheel, take up the lubricant,
and deliver it, as before, into the lubricant chamber.
When the lubricant overflows the lip of the chamber, it will run down the sido
passage in which the disc or wheel rotates. Collars are fixed on the shaft within the
side passages to prevent the oil escaping along the shaft, and so being wasted.-The
cap or cover of the plummer block is made to interlock, at its edges, with the pluminer
block, in such manner as to prevent the working out of the lubricant at the junction
of those parts.
In place of the above described disc or wheel and scraper, a dish shaped disc may
be used, which will pick up the lubricant on its inner periphery, and deliver it to a
gutter-shaped scraper set within the curve of the disc, and having a vent for discharging
the lubricant into the chamber, as in the first arrangement. For lubricating the crank
pins of engines according to this invention, the head of the connecting rod or piston
rod, as the case may be, is made to carry a reservoir, which is dish-shaped, and covers
the end of the crank pin. A sight hole fitted with glass is made in this cover to show
the quantity of lubricant in the reservoir and the action of the apparatus. A disc
keyed to the crank pin dips into the reservoir, and a scraper is provided for taking the
oil from the disc and delivering it to the brasses.-Near the inner end of the brasses,
an annular groove is turned to catch the lubricant (as it works its way along the crank
pin), and deliver it by a lateral passage made through one of the brasses back to the

page_text: reservoir. The scraper is made double, as above described, when it is desired to
provide for the turning of the crank pin in opposite directions.

SPECIFICATION.
Improvements in Lubricating Apparatus.
I JOHN ARMYTAGE BATLEY of 1. Elvaston Place, Queen's Gate, in the County of
Middlesex, Barrister at Law, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of this invention is to provide the brasses and journals of shafts or
axles, and also crank-pins, with an automatic supply of oil or other lubricant, the
supply varying with the speed of rotation of the parts to be lubricated, and the
surplus being returned to a reservoir, ready to be circulated through the lubricating
apparatus.
In the accompanying drawings, I have shewn the invention, by way of illustration,
as applied both for lubricating a shaft in its bearing, and the crank pin of a
connecting rod.
Fig. 1 is a longitudinal section of a plummer block such as I employ in carrying
out the object of this invention, the journal of the shaft to be lubricated being in
place; and
Fig. 2 is a cross section, on line 1. 2 of Fig. 1.
A is the plummer block, fitted with brasses B, B, as usual, for the reception of the
journal B of the shaft, and closed by the cap A-This plummer block is formed
with a reservoir a, below the lower brass or bearing for the journal, and from the
opposite sides of this reservoir rise chambers a¹ and a², leading upwards to, and above.
the top brass or bearing.
Secured to the shaft to be lubricated, is a disc b, which, by its rotation, is intended
to bring up, from below, the lubricant that is to be supplied to the journal. This disc
is enclosed in the chamber a of the plummer block, and may dip into the lubricant in
the chamber, but I prefer to insert in the chamber a' (as shown in the drawings) a
vessel, which takes a regulated supply of lubricant from the supply chamber a¹, and
presents it to the rotating disc b.-In the side of the vessel &, near its bottom, is a
small hole for the admission of the lubricant thereto, the supply of which may be
regulated by a pointed screw 62, tapped into a hole in the end of the plummer block,
and opposite the hole in the case The edge of the disc is shewn as square, and, on
it the lubricant collects as the disc is rotated, to be removed by the action of a loose
pressing scraper C.-This scraper, which is of peculiar construction, rests loosely
on the top of the disc b, and is held down upon it by a pressure spring D, to which
it is attached, and which is fixed to the cap A¹ of the plummer block. This
scraper C is shewn detached at Fig. 3, in plan, end view, and longitudinal section,
and the spring D which carries it, is shewn detached and in plan at Fig. 4.
To enable the scraper to act upon the lubricating disc, irrespective of the direction
of its rotation, I prefer to make it double, as shown at Figs. 3, so that it will embrace
a portion of the periphery of the disc, and present a scraping edge to the disc at
opposite sides of its centre of motion. The spring D, it will be seen, is screwed to
the cap of the plummer block, and extending over the scraper, projects into notches
cut in the inner faces of a pair of lugs standing up from the back of the scraper ;
the loose connection between the scraper and its pressure spring, enables the scraper
to follow any lateral vibrations of the disc, due to the endway motion of the shaft
or axle in its bearing..
A passage in the scraper leading from each point of contact with the periphery of

page_text: the disc b, conducts away the lubricant in a lateral direction, and delivers it in a
stream into a channel a in the cap A', above the top brass, which channel is cast
with a raised lip a', for retaining a supply of lubricant. A hole, as at a³, is made
through the cap and top brass, to allow the lubricant to run down from the channel
to the journal.
By connecting the scraper with the pressure spring D, as described, not only will
the scraper C be free to follow the lateral movements of the disc b, due to the wear
of the bearing surfaces, but it will, under all circumstances, maintain contact with
the periphery of the disc, take up the lubricant, and deliver it into the lubricant
channel u³.
When the lubricant overflows the lip a', it will run down the chamber a', to
enter again the vessel 1, in which the disc rotates. To prevent the oil escaping
along the shaft in either direction, and so being wasted, collars 3, 4, or their
equivalent, are provided within the side chambers a', a². These collars may either
be formed on the shaft, or fitted thereto, or one may form a portion of the
lubricating disc, but in any case I prefer to turn an annular groove in their
periphery, which will form an effectual bar to the progress of the lubricant along
the shaft, and the exudation of the lubricant from the bearing.
The cap or cover A¹ of the plummer block is made to interlock, at its edges, (see
fig. 1) with the plummer block, in such manner as to prevent the working out of the
lubricant, at the junction of those parts.
In place of the above described dise and scraper, a dish-shaped disc may be used,
which will pick up the lubricant on its inner periphery, and deliver it to a gutter
shaped scraper, set within the curve of the disc, and having a vent for discharging
the lubricant into the channel in the cap of the plummer block, as in the arrangement
above described.
For the lubricating of slowly rotating shafts, I prefer to form the disc with
a flange or rebate on its periphery, as illustrated at Fig. 4, using a corresponding
form of scraper edge to remove the lubricant brought up by the disc and hold in the
angle of the rebate.
Figs. 5 shew detached, in partial section and end elevation, a modified form of
scraper suitable for high speeds. This scraper is constructed substantially like that
already described, but is made to embrace a larger portion of the periphery of the
disc, in order that it may neutralize the centrifugal action imparted to the lubricant
when the disc is rotating at a high speed.
For lubricating the crank pins of engines according to this invention, the head of
the connecting rod or oscillating piston rod, as the case may be, is made to carry a
reservoir, which is dish-shaped, and covers the end of the crank pin. A sight hole,
fitted with glass, is made in this cover, to show the quantity of lubricant in the
reservoir and the action of the apparatus.
This arrangement is shewn at Fig. 6, which is a plan view, partly in section, of
the head of a connecting rod, fitted to a crank pin, the improved lubricator being
applied thereto :-and
Fig. 7 is a side elevation, partly in section, of the same, the section being taken on
the line 3. 4 of Fig. 6.
Fig. 8 shews, detached and in side view, the scraper employed in the crank pin
lubricator; and
Figs. 9 shew, detached, the two parts forming the scraper.
In these views, A is the connecting rod head, fitted with brasses B B, to receive
the crank pin B', which is formed with a grooved collar to check the flow of the
lubricant away from the reservoir.
Ը,
Keyed to the end of the crank pin is a disc b, which rotates in a reservoir
formed by a dish shaped cap piece A' secured by screws to the outer face of the head
of the connecting rod A.-A tapped hole in this cap piece, closed by a screw a*, is
provided for admitting the lubricant to the reservoir. Within the space covered by
the cap piece A', is a bracket piece C, which is secured by pins to the head piece A,
and serves to carry a scraper C.-This scraper is pivotted to its bracket, and held in

page_text: contact with the disc by means of a spring D, which is secured at one end to the
scraper, and at its other end underlies a pin projecting from the bracket.
The inner side of the scraper, near its extremity, is chamfered, for the purpose of
allowing the lubricant scraped from the periphery of the rotating disc, to rise up and
enter an opening c made through the bracket C.-Coinciding with this opening c in
the bracket, is an inclined channel leading from the outer end of one of the brasses B
to the crank pin B.-As, therefore, the lubricant is taken up by the scraper, and
delivered to the channel at the back of the brass, it will flow down through the brass
and lubricate the crank pin.
In the face of the brasses, near their inner end, an annular groove c¹ is turned, to
patch the lubricant (as it works its way along the crank pin).This annular groove
delivers the collected lubricant by a lateral passage e' made through one of the brasses,
back to the reservoir «.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. The arrangement of lubricator above described with reference to the drawings,
for automatically supplying lubricant to the brasses and journals of shafts and
axles.
2nd. The means above described for delivering the lubricant to the rubbing surfaces,
and providing for the reversal of the direction of rotation of the lubricated shaft
or axle.
3rd. The arrangement of automatic lubricator described with reference to the
drawings, for lubricating crank pins and returning the overflow to the reservoir.
4th. Mounting the scraper as above described, whereby it is free to follow
the lateral movements of the lubricating disc, and maintain its pressure on the
periphery thereof.
5th. In a lubricating disc, the employment of a flange on the periphery of the disc,
as and for the purpose herein set forth.
6th. The means above described for stopping the travel of the lubricant lengthwise
of the shaft, axle, or crank pin.
