Abstract
Abstract Conversion of a conventional mechanical fuel pump price setting variator for extending the conventional three place unit volume price range of the variator to a four place unit volume price range and comprising an auxiliary multiple step cone gear radially offset from and driven by the primary multiple step cone gear and selectively engageable by the conventional highest order range arm to extend its available price range into an additional higher order place, and auxiliary price indicator means operable by the highest order range arm to display the highest two places of an established price within the extended price range.

In a unit volume price variator for a mechanical fuel pump computer settable for establishing the amount of each place of a multiple place unit volume fuel price and having an input adapted to be driven by a fuel meter in accordance with the volume of fuel delivered, a multiple gear primary gear stack driven by the variator input in one angular direction, a plurality of range arm assemblies for the multiple places respectively having respective range arm shafts with axes radially offset from and parallel to the axis of the primary gear stack and respective range arms shiftable pivotally and axially on the range arms shafts for selective engagement with the gears of the primary gear stack, and combining gearing for combining the range arm outputs to provide relative drive ratios through the range arms in accordance with a geometric progression having a common ratio of ten, and at least one set of a plurality of price wheels for the multiple places respectively each operably connected to the respective range arm assembly for displaying the amount of the respective place of the unit volume price established by the range arm setting, the improvement wherein the variator further comprises a multiple gear auxiliary gear stack rotatably mounted about an axis parallel to and radially offset from the axes of the primary gear stack and highest place range arm shaft for selectively pivotally and axially shifting the highest place range arm into engagement with each auxiliary gear of the auxiliary gear stack, the primary gears of the primary gear stack providing relative drive ratios in accordance with the arithmetic progression 1a; 2a; 3a; . . . 9a; where a is a positive whole number, and the auxiliary gears of the auxiliary gear stack providing relative drive ratios in accordance with the arithmetic progression 10b; 11b; . . . ; where b is a positive whole number, and drive means for driving the auxiliary gears with the variator input in the same angular direction as the primary gears whereby the highest place range arm is engageable with the auxiliary gears to extend the available price range of the variator an additional place.
Claim 3
Dependent Claim
34 words
The variator according to claim 1 further comprising auxiliary price posting means operable by the highest place range arm to post the extended unit volume price portion of the price range of the variator.
Claim 4
Dependent Claim
59 words
A variator according to claim 2 wherein the auxiliary price posting means comprises a range arm sensor shiftable by the highest place range arm as it is shifted into engagement with the auxiliary gears and in accordance with the selected auxiliary gear, and price display means operable by the shiftable sensor to display said extended unit volume price portion.
Claim 5
Dependent Claim
49 words
A variator according to claim 3 wherein the sensor is mounted to be shiftable along an axis generally parallel to the axis of the auxiliary gear stack and to be axially shifted by the highest place range arm as it is axially shifted for engagement with the auxiliary gears.
Claim 6
Dependent Claim
35 words
