AUNIQUE; type of motor spirit pump has recently received the approval of the Standards Department of the Board of Trade. It is known as the Theo-Samoa, Model B6, and is sold by Theo and. Co., Ltd., 32, Tarleton Street, Liverpool, with equipment for electrical or hand operation, the prices being .£160 -and £140 respectively. With the TheoSamoa appliance it is claimed that, as a result of its special construction, six different kinds of 'spirit can be served from the single pump without mixing; thus enabling the owner to make a large " saving in capital outlay and .garage space.
A strung cast-iron standard forms the basis of the pump—this can be bedded in . concrete or on a cast-iron Plate. The standard .ia surmounted by a 5-gallon reservoir of thick glass for measuring purposes. The glass is protected by a Metal toP and cage. A. baffled sliding tube acts its an adjustable gauge which enables the operator to determine the amount of spirit to be
pumped into the reservoir. A. wheel, acting on a pinion and.rack inside.the standard, allows the gauge to be easily controlled. Moreover, the supply can be quickly switched from one brand of spirit to another, an efficient indicator being provided to show which liquid is being delivered.
Naturally, several storage tanks are necessary with the Theo-Samoa Pump. so the appliance is fitted with an auto
matic 'locking device which prevents the possibility of the spirit being transferred accidentally from one container to
another. Another locking apparatus keeps the delivery tap closed until the required quantity of fluid is in the glass reservoir. An unusual feature is the provision of means whereby the-spirit can be evacuated from the reservoir under pressure instead -of by gravity should it be needed for filling a tank situated above the level of the glass reservoir of the pump.
Largely owing to the fact that the spirit is drawn from the tanks direct to the reservoir by an air pump, no liquid previously drawn remains in the pipes, these being always empty except during the actual period in which suction takes place.
The apparatus is simple to operate, and an important advantage is that its installation, means a saving in rates and insurance, as the assessment for the owner is calm:dated on one pump instead of six, this being a specially economical feature.
