1 EDMUND OCTAVIUS EATON of No. 18 Martins Lane in the County of Middlesex
Merchant Partly a communication to me from abroad by James Lancaster of New
York, U.S.A. and partly my own Invention, do hereby declare the nature of this
invention to be as follows:-
This Invention relates to a pump designed for pumping up and measuring oils and
other liquids, the object being to force a given quantity of the liquid from the pump
at each stroke or revolution of the crank, whereby the liquid can be accurately
measured as is delivered from the pump.
The pump can be made of any suitable metal or material & mounted upon any
suitable frame or stand.
A dial & pointer of a registering mechanism for indicating the revolutions of shaft &
handle may be affixed to the pump. Any of the usual methods of registering devices
can be employed for indicating the revolutions of the shaft.
The pump consists of the ordinary barrel of cast iron or steel, or any other suitable
metal, with the usual piston rod sliding up and down.
Attached to the top of the piston rod is a horizontal slotted arm. A crank pin
traverses the slot, and is attached by any known method to, or cast, or welded in the
same piece with the crank.
The crank is welded or cast, or in any other way connected with a cylindrical
shaft. The said cylindrical shaft fits into an eccentric cylinder, and can be so adjusted
as to be secured at any part of the inner circumference of the said eccentric cylinder.
The latter revolves in a support or arm attached to the barrel of pump, and the handle
is fitted to the said eccentric cylinder by any known method. A pipe in the shape of
a syphon fits into the top of barrel, and an ordinary arrangement can be attached to
syphon, so as to attach the vessel to be filled.
This arrangement can be attached to any part of syphon so as to suit vessels of
various sizes.
The syphon can be fixed so as to hang over any part of the barrel.
To prevent
waste a trough and waste pipe is attached to pump; the waste pipe leading back into

page_text: the barrel or cask, which can be placed immediately under the pump, or in a cellar
removed from the salesroom.
By means of the eccentric cylinder the amount of liquid raised by the piston is
regulated, as will be hereafter explained.
The method of working the pump is as follows.
The handle is turned, and being firmly secured to the eccentric cylinder, the latter
revolves, setting in motion the crank, the crank pin traversing the slot, and thereby
raising & depressing the piston rod. The length of stroke made by piston rod
depends on the position in which the before mentioned shaft attached to crank is
fixed in the inner circumference of eccentric cylinder; and can be regulated so as to
increase or diminish the stroke of piston rod within the limit of size of each cylinder,
for the purpose of regulating the precise quantity of liquid to be discharged at each
stroke or revolution of the crank. It can thus be regulated so as to secure the
requisite length of stroke necessary to deliver the quantity of liquid at each stroke or
revolution, for which the pump is designed, say 1 pint or one gallon, for example, for
1 stroke or revolution.

page_text: I EDMUND OCTAVIUS EATON of 28 Martins Lane Canon Street London E.C. (partly
communicated by James Lancaster United States) 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 certain improvements in pumps for pumping and
measuring oils and other liquids the object being to force a given quantity of the
liquid from the pump at each stroke or revolution of the crank at the same time to
acurately measure the liquid as it is delivered.
In carrying the invention into practice a barrel of cast iron steel or any other
suitable material is provided wherein works a piston to the top of the piston a slotted
arm is attached in any convenient manner.
To the top or lid of the pump barrel is fastened in any convenient or desired
manner a standard the top whereof is formed as a bearing in this bearing the driving
shaft works and said driving shaft is recessed at the inner end eccentrically and into
this eccentric hole one arm of a crank is placed and fits closely therein the outer arm
being fitted and sliding in the slot of the arms at the top of the piston rod. In order
that the said invention may be more clearly understood there is annexed hereto two
sheets of drawings wherein Fig. 1 is a side view showing the top of the pump barrel
piston rod, slotted arm crank shaft and cylinder. Fig. 2 end view of same. Fig. 3
side view of slotted arm and piston rod showing crank arm in slot of arm of piston
rod. Fig. 4 view of crank and arms. Fig. 5 side view of eccentric shafts.
A is the top of the barrel; B the the piston rod; C the slotted arm; D the
standard; E the bearing for driving shaft. F. G the crank and G' the arm thereof
which slides in the slotted arm C, C is the slot in the arm C. G2 is the arm of
crank G which takes into eccentric hole H of driving shaft. F' is a screw for
holding the arm G² in the eccentric hole H. I is the piston as shown in Fig. 3, the
handle for working the pump will be attached to JJ Fig. 5.
The pump can be made of any suitable metal or material and mounted on any
suitable frame or stand a dial or pointer of a registering mechanism for indicating
revolutions of shafts and handle may be affixed. Any of the usual methods of
registering can be employed for indicating the revolutions of the shaft.
The method of working the pumps is as followes.
The handle is turned and being firmly screwed in the eccentric hole the latter
revolves setting in motion the crank G and the crank pin G' traversing the slot (¹
thereby raising and depressing the piston rod B.
The amount of throw of the said piston rod depends on position in which the
arm G attached to crank G is fixed in the eccentric hole H and be regulated
accordingly. Thus if the arm G2 is attached so that the crank G falls across the

page_text: narrowest part in the end of the eccentric hole H the piston rod will ascend higher or
descend lower than it would if the crank fell immediately across the widest part in the
end of the said cylinder thus giving the piston rod greater throw it can be thus
regulated.
Having now described the nature and particulars of my said invention and in
what manner the same is to be performed I declare that what I claim is :—
The improved measuring pump as herein set forth and shown by the drawings.
