An Improved Appliance or Pump applicable for Applying, by
Ejecting, or for Mixing, Liquids.
I, HENRY HARINGTON LEIGH, Assoc. M. Inst. C.E., Fel. Ch. Inst. P.A., F. I. Inst..,
practising as Phillips and Leigh, of No. 22 Southampton Buildings, Chancery Lane,
in the Administrative County of London, Engineer and Patent Agent, do hereby
declare the nature of this invention to be as follows.
The present invention relates to improvements in mechanism for dealing with
fluids by way of applying them to surfaces, of distributing them or of mixing them
and is capable of numerous industrial applications.
Made up as a lubricator, it is capable of discharging the Inbricant to as many
points and in any quantity, as may be desired.
Made up as a distributor, it is capable of sending any liquid to as many points as
may be desired and in any quantity.
Made up as a mixer, it is capable of mixing several liquids together and of dis-
tributing the mixture.
The mechanism is identically the saine whether its function is to be that of
lubricator, distributor or mixer, subject to the following slight modifications,
namely:-
As a simple lubricator there would be one tube at the side for suction and another
for ejection.
As a distributor there would be one tube at the side for suction and several for
ejection.
As a mixer there would be several tubes at the side for suction and one for
ejection.
The quantity of the liquid distributed in a given time depends upon the speed at
which the apparatus is worked and also upon the cross section of the tubes.
The invention includes the following organs possessed of the relative functions
described.
Three shafts are mounted parallel with each other in suitable bearings. The
second one is tubular and includes the third within it.
The first shaft drives the second through two eccentric gear wheels fast on the
respective end of each shaft; and the third one, by a similar pair of gears arranged
on the respective shafts by the side of the first pair, but the two driven shafts are so
speeded that as one is attaining its maximum velocity, the other of them is slacken-
ing its speed as it approaches its minimum.
Each of one of the ends of the second and third shafts is fitted with an
enlargement somewhat conical in external contour, the major diameter being nearest
to the middle of the shaft. Both these enlargements are at the same end of the
pair of shafts in question, and the smaller end of the larger enlargement fits into a

page_text: cavity in the larger end of the smaller one. These enlargements are not complete
cones, the smaller end of the larger one and the larger end of the smaller one being
both reduced to a segment or sector, each of an are small enough to leave vacant
spaces between the two enlargements.
The three shafts above described with their gearing may be supported in a block
or frame from the front of which the pair of enlargements project, presenting there
a conical external contour. Over this projecting cone, there fits a fixed casing or
box. Between the latter and the end of the cone (being the enlargement on the
inner shaft of the two), there is a spring in compression; and a second one between
the back of the cone (being the enlargement on the outer shaft of the two) and an
abutment in the above mentioned block or frame; the effect of the two being to
keep the enlargements pressed together, and as the spring behind the larger
enlargement is stonger than the other one, the casing or box above mentioned and
the smaller enlargement are kept fitting tightly to each other.
Pipes radiate from the interior of the box or casing where the surface of the cone
is in contact with it. The two shafts with their above mentioned sectors, in
consequence of the eccentricity of the gears and the relative positions of the latter,
rotate first quickly and then slowly; with the result that the two sectors, one on
each enlargement first approach and then move away from each other.
Seeing that the space in which the sectors above mentioned work, is practically
an air tight chamber, their movement away from each other tends to create a
vacuum, into which any liquid into which dip the free ends of the radial pipes above
mentioned, will be forced naturally, through the several pipes in order as their
months are uncovered. The reverse motion of the sectors will naturally have the
effect of expelling the said liquid.
The essential parts of the invention are the two sectors, the box in which they
work, the pipes, the two shafts and the two sets of eccentric gears.

COMPLETE SPECIFICATION.
An Improved Appliance or Pump applicable for Applying, by
Ejecting, or for Mixing, Liquids.
I, HENRY HARINGTON LEIGH, Assoc. M. Inst., C.E. Fel. Ch. Inst. P.A., F.I. Inst.,
practising as Phillips and Leigh, of No. 22, Southampton Buildings, Chancery Lane,
in the Administrative County of London, Engineer and Patent Agent, 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:-
This invention relates to means for oiling machinery and the object thereof is to
provide an improved apparatus for this purpose by means of which the oil or lubricant
may be conveyed to as many different points as desired and in any required quantity,
a further object being to provide means whereby the oil or lubricant may be properly
distributed to the various parts of the machinery and by means of which the various
lubricants may be mixed and distributed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which:
Figure 1 is a sectional side view of the apparatus which I employ, and
Figure 2 a cross-section on the line 2-2 thereof.
In the drawing formning part of this specification, the separate parts of my improve-
ment are designated by the same letters of reference throughout the several views,

page_text: and in said drawing I have shown at A a circular box which is closed by a base B, by
which it is supported.
I have also shown at C a driving shaft which by the eccentric gearing c and cl
turns the shaft D, while by means of the eccentric gear wheels e and e¹ the shaft E
is turned; that is to say, while the wheels c and cl communicate slow motion to the
shaft the wheels e and e¹ communicate quicker motion to the shaft E and
vice versu.
The shaft D passes through the shaft E and said shafts have the same imaginary
axis, and each is provided at its extremity with a conical head or seat, the conical
head or seat on the shaft D being designated by the reference letter D¹, and that on
the shaft E by the reference letter E¹, and these heads or seats are enclosed in
the box A.
The shafts D and E are each provided between the heads or seats D¹ and the E¹
with a sector, the sectors of the respective shafts D and E being designated by the
reference letters F and G respectively and the shafts D and E and their respective
sectors F and G revolve in the box A, while the head or seats E¹ and D¹ of the
shafts E and D are pressed against each other by the springs R and r, the spring R
being mounted on the shaft E, and the spring r in an extension of the box A.
The spring R is stronger than the spring r and the two heads or seats E' and D¹
are at the same time adjusted against the box A in such manner that the tightness
thereof in the box A, is perfect without the help of other fittings.
I also provide a number of tubes or pipes K and K¹ which are mounted in radial
bores or passages k, which are formed in the box A and which communicate with the
interior of said box, and the shafts D and E with their sectors F and G in consequence
of the eccentricity of the driving gearing and the manner or position in which the
same is arranged, take a rotary movement which is gradually accelerated or slackened
in such manner that the two sectors alternately approach and separate.
It will therefore be readily understood that while the sectors are separating, they
will operate to draw oil or other lubricants through the tube or pipe K¹ into the space
hetween the sectors, said tube or pipe being so placed that its outer end will be in
the oil or lubricant, and may be filled with the oil or lubricant as will be readily
understood, and the outer end thereof closed. But as the space between the sectors
is continually increasing or decreasing, the result is that if a number of tubes K, K¹
are placed in position while the separation takes place, the suction will take place in
each of them successively, or the oil or lubricant will pass through each successively
into the space between the sectors, and in the same manner, while the sectors are
approaching each other, the space between them diminishes or decreases and at the
same time the lubricant between the sectors is displaced and forced outwardly into or
through the pipes K, which will convey the lubricant to the points where these pipes
end.
The apparatus shown in the drawing and described in this specification is presented
as an example of the practical application of the invention, but the same may he
varied in its details in many ways.
The essential features of the invention consist of the two sectors adjusted in a
circular box, and fixed separately upon two shafts, said shafts being provided with
the same imaginary axis, and these two shafts being provided with a rotary movement
alternately accelerated and slackened in such a manner, that the sectors fixed upon
them approach and separate alternately and draw in or repel a liquid or lubricant
through a number of pipes placed around the box, in which they are mounted.
The mechanical devices or constructions, which may be employed to obtain this
result, are very numerous, and my invention is therefore not limited to the exact
form, construction and arrangement of the various parts thereof, herein described.
Having now particularly described and ascertained the nature of my sid
invention and in what manner the same is to be performed, I declare that what
Lclaim is

page_text: In a mechanical lubricant mixing and distributing apparatus, the combination of
two sectors adjusted in a circular box, and fixed separately upon two rotating shafts
having the same imaginary axis, said box being provided with radial bores in which
are placed pipes or tubes, and driving gearing which communicates a rotary move-
ment to the two shafts which is alternately accelerated and slackened so that the
sectors which are fixed upon said shafts alternately approach and separate,
substantially as shown and described.
