I, PATRICK MOLYNEAX, of Atlantic Wharf, Hogood Street, Devon's Road,
Bow Common, in the County of Middlesex, Wharf Manager, do hereby declare
the nature of this invention to be as follows:-
My invention relates to the safe transit of petroleum, oil, spirit, turpentine,
or other inflammable liquids, from the wholesale merchant to the retailer, and is
designed to simplify and cheapen such transit through the streets, and to prevent
the risk and danger possible under such circumstances, where inflammable liquids
may be tampered with, carelessly handled, or ignited.
My improved method consists in so transferring and storing the oil, spirit, or
inflammable liquid in bulk, in properly protected and hermetically closed tanks
and carts, so that there is no contact of the inflammable liquid with the atmosphere
in the transit from the wholesale to the retail dealer, whereby the chief danger of
its ignition is avoided; nor under my improved method, can the inflammable liquid
be left about on the pavements, or in the shops, in casks, in the manner usually at
present employed, whereby it is easily tampered with, spilt, or ignited, by careless,
or malicious handling.
The apparatus by which I carry this method into effect is as follows:-
I employ a special cart, consisting of a hermetically closed tank, mounted upon
a suitable cart body, for the transit of the petroleum, spirits, or other inflam-
mable liquid, through the streets. This tank cart is conveniently filled by a
pump from the usual storage tanks of the wholesale merchant. The said tank cart
is provided with a suitable man hole, closing hermetically, the cover of which is
conveniently a screw union for the attachment of hose, by which the tank-cart
may be filled with the liquid. It is also provided with an exit cock at the lowest
binder corner.
I provide also an air-tap at a suitable position on the tank cart, to operate
automatically or by the attention of the man in charge, to maintain atmospheric
equilibrium, whilst the petroleum or other liquid is being discharged by gravity.
The set of the tank on the cart body is so adjusted that all liquid drains to this
aforesaid corner, and the aforesaid exit tap is fitted into the bottom of a special
well, so that the whole of the contained liquid may be discharged by gravity from

page_text: the said tank-cart. Thus, the said tank cart will be ready, after discharge, for a
further load of oil, spirit, or liquid, to that which it has previously contained, since
the former contents will have been wholly discharged.
For delivery to the retail dealers, I provide a meter and hose pipe to the exit of
my tank cart, so that any required supply is delivered from the said tank cart, by
gravity, and measured by the aforesaid meter.
I may protect the interior of such a tank cart (which will be conveniently
constructed of iron) by galvanising, or by coating the interior with any suitable
composition capable of resisting the action, and preventing the leakage of petroleum,
oil, or other spirit.
To complete my method of storage, I propose that each retail dealer receives his
supply of petroleum, oil, spirit, or other inflammable liquid from the aforesaid tank
cart, into a tank, sunk in the basement or floor of his establishment Such tank
may be constructed of iron or concrete protected internally by any suitable com-
position, capable of resisting the action, and preventing the leakage of petroleum,
oil, or other spirit. Such tank will be provided with a suitable opening viz: a
union to which the hose pipe from the aforesaid tank cart can be attached direct,
and which may afterwards be closed hermetically with a suitable cover or cock.
An air pipe, closed with a cock, is provided in the upper part of the tank, by
which atmospheric equilibrium may be maintained by the opening of the said cock
when necessary, viz: when the tank is being filled or emptied.
To facilitate the delivery of such petroleum oil, spirit, or other inflammable
liquid to the retail purchaser, under my improved method for greatest safety, I
propose that such retailer shall use a suction pump, operated similarly to a beer
pull as fitted to bars. He can thus deliver from the before described sunk storage
tank such quantity of petroleum oil, spirit, or other inflammable liquid, as may
be required, into suitable cans or vessels for removal by the retailer.
Dated this 1st day of December 1885.

page_text: An Improved Method of and Apparatus for the Safe Transit and
Storage of Petroleum, Oil, or other Inflammable Liquids.
I, PATRICK MOLYNEAX, of Atlantic Wharf, Hogood Street, Devon's Road, Bow
Common, in the County of Middlesex, Wharf manager, 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:-
My invention relates to the safe transit of petroleum, oil, spirit, turpentine, or
other inflammable liquids, from the wholesale merchant to the retailer, and it is
designed to simplify and cheapen such transit through the streets, and to prevent
the risk of danger possible under such circumstances, where inflammable liquids
may be tampered with, carelessly handled or ignited.
My improved method consists in so transporting and storing the oil, spirit or
inflammable liquid in bulk in properly protected and hermetically closed tanks
and carts, so that there is no contact of the inflammable liquid with the atmosphere
in the transit from the wholesale to the retail dealer, whereby the chief danger of
its ignition is avoided, nor under my improved method need the inflammable liquid.
be left about on the pavements, or in the shops, in casks, in the manner usually
at present employed whereby it is easily tampered with, spilt, or ignited, by careless,
or malicious handling.
In order that my invention may be the better understood I now proceed to
describe the same in relation to the sheet of drawings hereunto annexed reference
being had to the letters and figures marked thereon. Like letters refer to like
parts throughout the figures.
Figure 1 is a rear elevation of my improved transporting vehicle.
Figure 2 is a side elevation of the same.
Figure 3 is a plan and
Figure 4 is a modified vehicle for transporting smaller quantities.
My vehicle is constructed as follows:-
I mount a hermetically closed tank A upon a suitable cart body for the transit of
the petroleum, spirit or other inflammable liquid through the streets. This tank
cart is provided with a suitable man hole B closing hermetically, the cover of which
may be a screw union for the attachment of the hose by which the tank cart may
be filled with the liquid; or I may provide a special filling aperture C. formed
with a screw thread to receive the nozzle of the hose leading from the tank, and
provided with an exit cock D at the lower hinder corner. I provide also an air
tap E at a suitable position on the tank cart to operate automatically, or by the
attention of the man in charge, to maintain atmospheric equilibrium whilst the
petroleum or other liquid is being discharged. The set of the tank on the cart
body is so adjusted that all the liquid drains to this aforesaid corner and the afore-
said exit tap is fitted into the bottom of a special well, so that the whole of the
contained liquid may be discharged by gravity from the said tank cart. Thus, the
said tank cart will ready, after discharge, for a further load of oil, spirit, or liquid
to that which it had previously contained, since the former contents will have been
wholly discharged.

page_text: For delivery to the retail dealers, I provide a meter F, and may fit a hose pipe
to the exit cock, so that any required supply may be delivered from the said tank
cart by gravity and measured by the aforesaid meter.
I may protect the interior of such a tank cart (which will be conveniently
constructed of iron) by galvanising or by coating the interior with any suitable
composition capable of resisting the action and preventing the leakage of petroleum,
oil or other spirit.
It will be convenient that each retail dealer shall receive his supply from the
aforesaid tank cart into a tank sunk into the basement or floor of his establishment.
Such tank may be constructed of iron or concrete protected internally by any
suitable composition capable of resisting the action and preventing the leakage of
petroleum oil or other spirit. Such tank will be provided with a suitable opening
and union to which the hose pipe from the aforesaid tank cart can be attached
direct and which may afterwards be closed hermetically by a suitable cover or cock.
An air pipe closed with a cock is provided in the upper part of the tank by
which atmospheric equilibrium may be maintained by opening the said cock when
the tank is being filled or emptied.
To facilitate the delivery of such petroleum, oil, spirit, or other inflammable
liquid to the retail purchaser under my improved method for greatest safety
I propose that such retailer shall use a suction pump, operated similarly to a beer
pull as fitted to bars. He can thus deliver from the before described sunk storage
tank such quantity of petroleum, oil, spirit, or other inflammable liquid, as may be
required, into suitable cans or vessels for removal by the retailer.
Though the method I have specified may be suitable for delivery to retailers who
store the oils or spirits in quantity yet for delivery in smaller quantities I fix to
the back of my cart a meter for smaller quantities consisting of a small reservoir G,
fitted with an exit tube H, and with a graduated gauge glass K, by which the
quantity withdrawn may be accurately measured. This is conveniently filled from
the body of the cart by a small pump L communicating with the interior of the
cart and the interior of the reservoir.
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:
1st. The combination in a vehicle for the safe transit of petroleum, oil or other
inflammable liquids of a tank fitted with suitable inlet and egress orifices, with 3
a measuring device for large or small quantities, substantially as and for the
purposes described.
2nd. The combination with such a cart or vehicle of a storage tank connected to
the exit by means of a hose, substantially as and for the purposes specified.
3rd. The combination with such a tank of delivery pumps substantially as 4
described.
