PROVISIONAL SPECIFICATION.
A New or Improved Appliance for Lubricating or Cleansing the
Bearings of Machinery
We, THOMAS BROCKAS, of Church Grove, Lewisham, Engineer, and SAMUEL
IRVING, of 35, Knowles Hill Crescent, Lewisham, Engineer, both in the County of
Kent, do hereby declare the nature of this invention to be as follows :-
The object of our invention is to provide an oiler and cleaner that will deliver oil.
or other fluid lubricant directly and with a considerable amount of force into bearings.
or parts of machines and may also be used for forcing a cleansing fluid such as
paraffin into such bearings or parts of machines.
In carrying out our invention we provide a suitably shaped reservoir or chamber
to contain the oil or lubricant which chamber may or may not be threaded or
screwed at the lower end thereof and which has in its upper part or top an orifice.
threaded to receive a screwed boss through which works a piston or plunger
hereafter described.
Through the centre of this chamber or reservoir and attached or screwed to the
lower part thereof we arrange a device consisting of two tubes one within the other
and provided with a piston or plunger capable of working within the inner tube and
passing through a gland in the boss or cover before mentioned.
The outer tube has a small hole near its foot and a slot of convenient length and
of nearly the diameter of the tube at its upper portion-the top and bottom of this
slot are curved upwardly or cam shaped.
The inner tube has also a narrow vertical slot in which a pin screwed into the
piston or plunger may slide and engaging with the curved or cam shaped ends of.
the slot in the outer tube cause the said tube to partially revolve so that the hole
therein may correspond with a hole in the inner tube, or close or cover the same as
required. The inner tube is permanently fixed or attached to a screwed base or
boss which engages with the orifice in the bottom of the chamber or reservoir and
terminates in a nozzle in the usual manner.
The upper portion of the piston or plunger is reduced in thickness so as to pass
through the gland in the boss or cover, and terminates in a head button or knob.
On the boss or cover we pivot an armed device or fork which has its upper
portion threaded to receive a thumb screw the lower end of which engages in a
socket on the head or knob before described and when screwed down thereon keeps
the plunger or piston close to its lower bearings and prevents any oil passing into
the nozzle. The upper portion of the piston or plunger passes also through a loose
gland and is surrounded by a spiral spring tending to keep the said piston up and
the orifice open when the protecting arm is removed by releasing the thumb screw.
The lower portion of the piston or plunger is packed so as to tightly fit the tube.
The piston rising by the action of the spring when the holdfast is released draws
the fluid from the chamber through the small orifice in the outer tube and so into
the inner tube whence it is ejected with some force through the nozzle by the
pressure of the thumb or the like on the knob or button, the tube being recharged
on the withdrawal of the pressure.
Oil is introduced into the reservoir or chamber through an orifice fitted with a
screw knob or other device.

A New or Improved Appliance for Lubricating or Cleansing the
Bearings of Machinery.
We, THOMAS BROCKAS, of Church Grove, Lewisham, Engineer, and SAMUEL
IRVING, of 157, Kirkwhite Street, Nottingham, and late of 35, Knowles Hill
Crescent, Lewisham, Engineer, do hereby declare the nature of this invention, and
in what manner it may be performed, to be as follows:-
The object of our invention is to provide an oiler and cleanser that will deliver
oil or other lubricant directly and with a considerable amount of force into bearings
or parts of machines and may also be used for the purpose of forcing a cleansing
fluid such as paraffin into such bearings or parts of machines.
Referring to the accompanying sheet of drawings and to the figures and letters
of reference thereon we will proceed to describe our invention.
Figure 1. is a perspective view of our improved lubricating appliance the
working parts being principally unseen and enclosed within the outer case or
reservoir.
Figure 2. is a vertical section through inner surrounded tubes and working parts
of the apparatus.
Figure 3. is a view of the internal tubes and working parts shewing their relative
positions when the plunger is at its lowest point and the lubricant free to enter the
inner tube.
Figure 4 shews the same with the plunger raised, the entrance of the lubricant to
the inner tube closed and the appliance ready for ejecting the lubricant on the
head of the piston being forced downwards.
Figure 5. is a view of the innermost tube into which the lubricant is drawn
previous to its being forcibly ejected through the nozzle tube.
In carrying out our invention we provide a suitable case, reservoir or chamber
such as A. Figure 1. to contain the lubricant in bulk and from which the successive
charges may be drawn into the inner tube hereafter described.
The lower extremity of this case may be threaded or screwed to engage with a
threaded or screwed nozzle or delivery tube or point such as B and the upper
portion of the case A may carry a tapped or threaded socket or orifice in which
engages a screwed boss attached to or surmounted by a flat thumb piece C and
through which as through a stuffing box passes a spindle or piston D terminating in
a removable head or cap E and normally held up by a spiral spring such as F
embracing said piston between the top of reservoir and cap E. This spindle or
piston terminates in a plunger G hereinafter further described. Attached to or
forming a portion of the nozzle B is a stationary tube H Figs. 2, 3 and 4, at the
lower portion of which is a small orifice 1 through which may flow the oil or
lubricant contained in reservoir A and be forced thence through the small tube b of
the nozzle or point B by the action of the plunger G and piston D. At the upper
end of the tube is a vertical slot J in which a pin K screwed into the piston or
plunger D may slide. This tube H is surrounded by a second moveable tube L
in which is a wider slot M with cam shaped ends and through this projects also the
pin K which partially revolves the tube L round the tube H on the rising and
falling of the piston. Near the bottom of the outer tube L is a hole or orifice N
through which the oil or lubricant contained in the reservoir A may pass and thence
through the hole I when the two orifices I and N become coincident by reason of
the forcing down of the piston and plunger. The working of the piston causes a
pumping action, the oil or lubricant being first drawn through the holes in the tubes
and then ejected through the nozzle B.
When not in use the piston or plunger is kept firmly down by a holdfast formed
as follows.
On the boss or thumbpiece C is provided at O a fork P through the head or

page_text: cross head of which works a screw Q terminating in a milled head R. When it is
desired to secure the piston the head of the fork P is brought over the cap E the
piston being depressed and the screw Q is turned until the piston is firmly held
home.
When the holdfast is released the piston rises, the fluid is drawn from the chamber
or reservoir A through the holes I and N into the inner tube H and forced out
through the nozzle tube 6 on the return of the plunger the tube being recharged on
the withdrawal of the pressure. Oil or other fluid is introduced into the reservoir
through a capped orifice or other device such as S.
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 :-
First In a lubricating can or appliance the use of a plunger working in a double
tube for the purpose of drawing into and ejecting from the inner tube through a
narrow nozzle oil or lubricant contained in an outer surrounding reservoir or
chamber, said plunger being kept normally up by a spring device and retained in a
depressed position when not being used by a forked hold fast or pivotted head
substantially as described as illustrated in the accompanying drawings.
Second The oiling or lubricating device or appliance substantially as described
herein and as illustrated by the accompanying drawings.
Dated this 12th day of March 1891.
