PROVISIONAL SPECIFICATION.
Improvements in or relating to Pump Operating Mechanism.
I, ROBERT GREENWOOD WARNER, of 27, Jewin Crescent, in the City of London,
Consulting Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object improvements in or relating to pump operating
mechanism and is designed for use with various characters of reciprocating pumps
especially where operated by a pivotted lever or handle of the ordinary character
of hand pumps.
For the sake of example I will proceed to describe my present invention as
applied to a hand lever pump of the ordinary well-known character.
The piston or plunger rod is extended beyond the pump barrel without any
joint (but as a rigid rod) for a suitable distance beyond the fulcrum or point on
which the handle or pump operating lever is pivotted and such plunger rod is
passed through any suitable bearing or bearings or guides such as eyes or plummer
blocks or other suitable device or devices beyond said handle pivot or fulcrum
or said guide or guides or bearings for said rod may be arranged between said
fulcrum and the pump barrel.
and
Thus this plunger rod can only move and reciprocate in a straight line.
To connect this rod to the swinging handle or pivotted lever aforesaid I form
the latter with an elongated eye or slot therein or an open forked end adapted
to fit over and receive therein a small roller or reel (advantageously a stout roller
with a flange at each side) which roller is carried on a pin fixed (at right angles)
to the aforesaid plunger rod whereby the motion imparted to the said forked or
slotted end of the handle or lever is transmitted through said roller and its pin
or axis to the pump rod the fork or slot allowing the said roller to travel along
therein as the said lever end moves across the line of motion of the pump rod.
Or these parts may be arranged vice-versa if desired.
I may use various modifications and obvious mechanical equivalents for carry-
ing out my invention as aforesaid.

I, ROBERT GREENWOOD WARNER, formerly of 27, Jewin Crescent, now of 97,
Queen Victoria Street, in the City of London, Consulting Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:
-
This invention has for its object improvements in or relating to pump-operating
mechanism and is designed for use with various characters of reciprocating pumps
especially where operated by a pivotted lever or handle of the ordinary character
of hand pumps.
For the sake of example I will proceed to describe with reference to the accom-
panying drawings my present invention as applied to a hand lever pump of the
ordinary character.
•
Referring to the accompanying drawings—Fig. 1 is a front view of a hand
pump having my present improvements applied thereto.
Fig. 2 is a local sectional view on line 2-2 Fig. 1 looking in the direction of
the arrow. 1.
The piston or plunger rod a is extended beyond the pump barrel without
any joint (as a rigid rod) for a suitable distance beyond the fulcrum c or point on
which the pump handle or pump-operating lever is pivotted and such plunger
rod a is passed through any suitable bearing or bearings or guides such as eyes
or plummer blocks or other suitable device or devices for instance a guide such
as e beyond said handle pivot or fulcrum c said guide or guides or bearings e
or
and
for said rod a may be arranged between said fulcrum c and the pump barrel b.
Thus this plunger rod a can only move and reciprocate in a straight line.
To connect this rod a to the swinging handle or pivotted lever d aforesaid I
form the latter with an elongated eye or slot d therein or an open forked end
adapted to fit over and receive therein a small roller or reel a (advantageously
a stout roller with a loose washer as shown at Fig. 2) which roller is carried
on a pin a fixed' (at right angles) to the aforesaid plunger rod a whereby the
motion imparted to the said forked or slotted end of the pump handle or lever d
is transmitted through said roller and its pin or axis a¹ to the pump rod a the
slot (or fork) allowing the said roller to travel along therein as the said lever
end moves across the line of motion of the pump rod a.
Or these parts may be arranged vice versa if desired as shown in Figs. 3 and 4.
Fig. 3 being corresponding view to Fig. 1 and showing this modified arrangement,
and Fig. 4 being local sectional view on line 4-4 Fig. 3 looking in the direction
of the arrow 3.
In this arrangement the eye or slot a is formed in or on the rod a while the
pump handle d is provided with a pin d upon which is mounted the roller
which operates in the slot a; the rod a passes through the guide e or may be
otherwise guided as before described.
I may if desired dispense with the use of the roller x or employ other obvious
modifications without departing from the true nature of my present invention.
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. In pump-operating mechanism-providing a pump handle such as d with a
forked end or slot such as d therein adapted to operate a piston or plunger rod

page_text: such as a held in guides substantially in the manner and for the purposes herein--
before described.
2. In pump-operating mechanism-providing a piston or plunger rod such as a
with a slot such as a therein adapted to be operated by the pivotted pump handle
such as d substantially as herein before described.
3. The improved arrangement and construction of pump-operating mechanism
substantially as herein before described and illustrated in the drawings hereunto
annexed.
