Abstract
Abstract A hand drive for manually operating a blender-type gasoline dispenser in the event of power disruption, including a crank operated shaft mounted for rotation and which is axially presettable relative to the pump drives for selectively operating either or both of the dispenser pumps. Laterally extending from the shaft are a pair of spaced pins for rotatably coupling the shaft with the drive sheave of the selected pump or pumps. Presetting the shaft axially with the pins in a first position rotatably couples the shaft via one of the pins to one sheave for high octane dispensing while the other pin and respective sheave remain disengaged. Setting the shaft in a second position rotatably couples the shaft via the other of the pins to the second sheave for low octane dispensing while the first pin and respective sheave remain disengaged. A third setting of the shaft intermediate between the first and second positions couples both sheaves for simultaneously operating both pumps to effect a dispensing of blended high and low octane fuels.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
In a motor driven blender-type gasoline dispenser including a first motor driven pump adapted for operable connection to a first source of low octane level gasoline for dispensing, a second motor driven pump adapted for operable connection to a second source of relatively high octane level gasoline for dispensing and blender means operative to simultaneously actuate both motors of said pumps for dispensing a blended mixture of the gasolines from each of said sources, the improvement which comprises a hand drive for manually operating said dispenser comprising in combination an operating shaft mounted for hand driven rotation, drive means drive connected individually with each of said pumps and selection means presettable to selectively connect said drive means with said operating shaft for optionally actuating said first pump alone, said second pump alone or said first and second pumps simultaneously.
Claim 2
Dependent Claim
139 words
In a motor driven blender-type gasoline dispenser including a first motor driven pump adapted for operable connection to a first source of low octane level gasoline for dispensing, a second motor driven pump adapted for operable connection to a second source of relatively high octane level gasoline for dispensing and blender means operative to simultaneously actuate both motors of said pumps for dispensing a blended mixture of the gasolines from each of said sources, the improvement which comprises a hand drive for manually operating said dispenser comprising in combination an operating shaft mounted for hand driven rotation, drive means drive connected individually with each of said pumps and selection means presettable to selectively connect said drive means with said operating shaft for optionally actuating said first pump alone, said second pump alone or said first and second pumps simultaneously.
Claim 3
Dependent Claim
60 words
In a blender-type gasoline dispenser according to claim 1 in which said hand drive means is supported in drive-free relation about said operating shaft and said operating shaft includes lateral offset means extending therefrom, said offset means being presettably positionable by said selection means to rotatably couple said operating shaft with the selected pump drive connection of said drive means.
Claim 4
Dependent Claim
50 words
In a blender-type gasoline dispenser according to claim 2 in which said selection means includes means to transversely displace said hand offset means relative to said drive means for said selection means to presettably couple said operating shaft with the selected drive connection for one or both of said pumps.
Claim 5
Dependent Claim
106 words
In a blender-type gasoline dispenser according to claim 3 in which said hand drive means includes spaced apart individual drive connections for each of said pumps, said operating shaft is supported rotationally free of each of said pump drive connections, said offset means comprises a lateral extension extending from said shaft at the location of each of said individual pump drive connections and said selection means includes means to axially displace said operating shaft longitudinally into one of a plurality of reference position settings for at least one of said extensions to couple said operating shaft with the drive means pump drive connection to be selected.
Claim 6
Dependent Claim
52 words
In a blender-type gasoline dispenser according to claim 4 in which each of the pump drive connections supported about said operating shaft defines an internal recess adapted to receive one of said lateral extension for coupling the operating shaft thereto in either of two reference position displacement settings of said operating shaft.
Claim 7
Dependent Claim
42 words
In a blender-type gasoline dispenser according to claim 5 in which said plurality of reference positions consists of three position settings for said operating shaft, one of said positions being common for the simultaneous coupling of both of said pump drive connections.
Claim 8
Dependent Claim
29 words
In a blender-type gasoline dispenser according to claim 6 in which said common reference position is located on said operating shaft longitudinally intermediate the others of said reference positions.
