Improvements in the Construction of Portable Hand Pumps.
SAMUEL BENJAMIN WILKINS 1 Parliament Square Edinburgh in the County of
Mid Lothian N.B. Fire Master of the City of Edinburgh do hereby declare the nature
of this invention to be as follows:-'
ог
Improvements in the construction of portable Hand Pumps for extinguishing fire
or other purposes to simplify and ease its workings thereby allowing it to be worked
at a much greater speed with considerably less Manual Labour. To carry this mode
of working into effect, I provide a disc plate or wheel on to which I fix a crank pin.
This disc plate or wheel is secured to a spindle or shaft, working through a pillow
block or bush. The pillow block or bush being supported by means of a bracket,
secured to the upper part of the pail or cistern, in which the pump may be placed.
To the other end of the spindle or shaft is fixed a handle for turning the disc plate
wheel round, which forms the pump motion. And to the upper or outer end of the
piston rod I form an eye. This eye is secured to the crank pin, and connects the
piston rod direct to the disc plate or wheel. And to still further simplify and ease
its workings, I construct the pump so as to oscillate when in motion, by placing two
pins or studs on the same. These pins or studs working through pillow blocks,
which may be supported on brackets or to the sides of the pail or cistern or otherwise.
These supporting the pump in such a manner, as will allow it to swing or vibrate,
when brought into use, and to prevent any vibration in the delivery hose when the
pump is swinging I provide a connecting peice, and secure it to a convenient part of
the cistern or bracket to which is attached a short peice of hose-piping between this
connecting peice and the delivery outlet on the pump I may also provide a metal cap
and screw the same into the underneath part of the bottom of the pail or cistern.
This will allow of the pump valves being examined, without removing the pump from
the cistern as also enabling it to work from a Bath, Tub, or any other vessel holding
water if placed in the same.
Dated this Seventh day of October 1887.

Improvements in the Construction of Portable Hand Pumps.
SAMUEL BENJAMIN WILKINS Parliament Square Edinburgh in the County of
Mid Lothian N.B. Fire Master of the City of Edinburgh. 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 :-
Improvements in the construction of Portable Hand Pumps for extingushing fire
or other purposes, to simplify and ease its working thereby allowing it to be worked
at a much greater speed with considerably less manual labour. To carry this mode
of working into effect, I provide a disc plate or wheel, on to which I fix a crank pin.
This disc plate or wheel is secured to a spindle or shaft working through a pillow
block or bush. The pillow block or bush being supported by means of a bracket
secured to the upper part of the pail or cistern, in which the pump may be placed.
To the other end of the spindle or shaft is fixed an handle for turning the disc plate
or wheel round, which forms the pump motion. And to the upper or outer end of the
piston rod I form an eye. This eye is secured to the crank pin and connects the
piston rod directly to the disc plate or wheel. To still further simplify and ease
its working, I construct the pump and support the same in any position which
would allow it to oscillate when in motion, but preferably place the pump in a
bracket of sufficient length, having two arms projecting from the same for supporting
the pump in the pail or cistern.
These arms revolving through pillow blocks or sockets secured to the pail or cistern,
and one of these arms being hollow forms the discharge nozzle, to which the delivery
hose would be. attached.. And. in order that my said. Invention: may be properly
understood I now proceed more particularly to set forth the system mode or manner,
in or under which the same is or may be used, or practically carried into effect,
reference being had to the annexed sheets of Drawings, and to the letters and figures
marked thereon, that is to say,
Figure (1) is an interior view.

(L) handles for assisting persons to carry the cistern and pump (N) driving handle

Figure (IV) shows a general side view.
By this arrangement of allowing the pump to oscillate when working will save a
great amount of manual labour which have hitherto been required to work the
ordinary hand-pumps in present use, by the same being fixed into a pail or cistern.
One great feature in these improvements is that they can be easily applied to any
existing hand-pumps at a reasonable cost.
Having now particularly described and ascertained the nature of my said invention
and the system mode or manner in or under which the same is or may be used or
practically carried into effect, and would have it understood that I do not intend to
limit myself to the exact details hereinbefore described and represented in the
drawings annexed, so long as the true character of my Invention is retained and in
conclusion I declare that what I claim is
An improved arrangement of apparatus, and means employed to support the pump
in a pail or cistern, from any position, that will allow the same to oscillate or vibrate
when brought into use.
In witness whereof I the said Samuel Benjamin Wilkins have here-unto set my
hand and seal this Fifth day of May One thousand eight hundred and eighty
