Abstract
Abstract An improvement in vehicle power take-off equipment is disclosed wherein a generator is affixed to the rear of the housing of a rotary air compressor of the type that is driven from a vehicle power take-off to an input shaft at its front end. The generator's housing is attached to the rear end of the air compressor's housing and the generator includes an armature mounted for rotation in the generator's housing. A rotary shaft extension projects from the rear of the air compressor. The armature receives the extension shaft and is coupled thereto by a friction fit and a threaded stud therebetween so that the armature turns with the extension shaft. The extension shaft is coupled for operation by the input shaft of the compressor so that both compressor and generator are directly operated by the input shaft of the compressor.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
209 words
Apparatus for operationally connecting a rotary screw air compressor of the type that has an elongated housing having a front and rear and said air compressor further being of the type which has at least one rotary screw mounted between said front and rear, and said rotary screw air compressor having a shaft which projects out the front where it constitutes a input shaft (39) for operating said rotary screw air compressor, with a generator of the type having a housing having a front and rear with an armature mounted in the housing for rotation between said generator's housing's front and rear, said armature having means for engaging an extension shaft, said apparatus comprising: a rotary screw shaft extension (34) coupled for operation by said input shaft (39), said rotary screw extension shaft (34) positioned at the rear of said compressor and projecting therefrom, said rotary screw extension shaft (34) having means for connecting it to said armature to turn said armature when received therein; and means connecting the front of said generator housing to the rear of said compressor housing with said extension shaft (34) so connected to said armature, whereby operation of said input shaft (39) of said compressor directly operates both said compressor and said generator.
Claim 2
Dependent Claim
209 words
Apparatus for operationally connecting a rotary screw air compressor of the type that has an elongated housing having a front and rear and said air compressor further being of the type which has at least one rotary screw mounted between said front and rear, and said rotary screw air compressor having a shaft which projects out the front where it constitutes a input shaft (39) for operating said rotary screw air compressor, with a generator of the type having a housing having a front and rear with an armature mounted in the housing for rotation between said generator's housing's front and rear, said armature having means for engaging an extension shaft, said apparatus comprising: a rotary screw shaft extension (34) coupled for operation by said input shaft (39), said rotary screw extension shaft (34) positioned at the rear of said compressor and projecting therefrom, said rotary screw extension shaft (34) having means for connecting it to said armature to turn said armature when received therein; and means connecting the front of said generator housing to the rear of said compressor housing with said extension shaft (34) so connected to said armature, whereby operation of said input shaft (39) of said compressor directly operates both said compressor and said generator.
Claim 3
Dependent Claim
40 words
The invention of claim 1, wherein said means for connecting said extension shaft to said armature includes a means defining a coaxial tapered bore for receiving said extension shaft and a threaded stud between said armature and said extension shaft.
Claim 4
Dependent Claim
31 words
The invention of claim 2, wherein said air compressor's housing's rear mates with said generator's housing's front and said means for connecting said housings together is a number of threaded fasteners.
