Abstract

A system including means and method for proportioning tax to vehicle efficiency-class at the fuel pump, including: provision of mandatory configuration of each vehicle filler neck in accordance with vehicle efficiency-class, coacting fuel-dispensing pump-nozzle structure to ascertain by the filler neck configuration the efficiency-class vehicle being fueled, and coacting pump structure to tax the quantity dispensed in accordance with the efficiency-class ascertained. In embodiment, a locking system for the fuel nozzle is released only by proper engagement with a receiver according to this invention. Stationary power plants and heating systems can be proportionally taxed as well as automotive air and water vehicles by means of the invention.

Claims

1. The method of apportioning surtax in dispensing fuel through a nozzle rotatably associatable with a filler tube in a fuel receiver in accordance with the fuel efficiency classification of the receiver, consisting of the steps:

(a) constraining rotatability of the nozzle with respect to the filler tube to a limit evidencing fuel efficiency classification of the receiver;

(b) requiring rotation of the nozzle to said limit when associated with the filler tube prior to fuel dispensing; and

(c) indicating the degree of rotation of the nozzle, as a measure of surtax apportionable;

thereby apportioning surtax in accordance with fuel efficiency classification of the receiver.

2. In a system for fuel dispensing having nozzle with a lug fixed thereon, a filler tube proportioned for receiving the nozzle rotatably therein and having an axial slot and a groove circumferentially extending from the axial slot proportioned for receiving the lug for locking together the nozzle and filler tube by means of lug rotation around the groove upon said relative rotation between nozzle and filler tube;

a source of fuel having fuel dispensing connection with the nozzle, means for conveying data about fuel dispensing, and a receiver of a particular fuel efficiency classification having fueling connection through the filler tube, the improvement comprising;

the data conveying means including means terminating the groove at a distance from the slot proportional to fuel efficiency classification of the receiver, and means displaying said distance the lug is rotated to the terminating means as a measure of receiver fuel efficiency classification.

3. In a system as recited in claim 2, means permitting dispensing of fuel through the nozzle only when the lug is rotated in the groove said distance to the terminating means.

4. In a system as recited in claim 3, the means displaying giving visual indication at said locking together of the nozzle and filler tube and comprising:

a first scale element on the filler tube in predetermined relation to the slot, and a second scale element on the nozzle in predetermined relation to the lug and located for positional coaction indicative of degree of rotation relative to the first scale element.

5. In a system as recited in claim 3, the means displaying including:

means on the nozzle for sensing said distance the lug is rotated to the terminating means, means at the source for remotely indicating said distance sensed, and means responsively connecting the means on the nozzle with said means at the source.

6. In a system as recited in claim 3, the means permitting dispensing of fuel through the nozzle only when the lug is rotated said distance to the terminating means comprising:

the source including means for supplying fuel upon electrical actuation, and the improvement further comprising means at the receiver for electrically actuating the means for supplying, when the lug is rotated said distance to the terminating means.
