Patent ID: 8028597

Claim:
A low horsepower transmission, comprising: a drive shaft configured for being operably coupled to a prime mover and extending along a drive shaft axis; a driven shaft extending along a driven shaft axis, the driven shaft axis being parallel to the drive shaft axis, the driven shaft being operably configured for being operably coupled to a rotary load the drive shaft axis and the driven shaft axis being on a first plane; first and second geared wheels being aligned and rotatably mounted on the drive shaft and the driven shaft, respectively, the first and second geared wheels being operable to transmit rotation therebetween; third and fourth geared wheels being aligned and rotatably mounted on the drive shaft and the driven shaft, respectively, the third and fourth geared wheels being operable to transmit rotation therebetween; a first clutch coupled to the second geared wheel on the driven shaft; a second clutch coupled to the fourth geared wheel on the driven shaft; a shaft axle orthogonally superposed over the drive shaft and driven shaft, the shaft axle operable for rotational movement in response to actuation of a pivot arm coupled thereto, the pivot arm traversing a plane orthogonal to the shaft axle said shaft axle extending parallel to the first plane; and a shuttle clutch slidably secured to the driven shaft for lateral movement thereon, the shuttle clutch operable to reciprocate between mating engagement with the first clutch and mating engagement with the second clutch, the shuttle clutch being coupled to a yoke that translates the rotational movement of the shaft axle into the lateral movement of the shuttle clutch on the driven shaft; wherein when the shuttle clutch mates with the first clutch, the first and second geared wheels transmit torque and when the shuttle clutch mates with the second clutch, the third and fourth geared wheels transmit torque.
