Abstract: A combination self-propelled lawn mower and wheeled cart for receiving and storing mower clippings. The mower is connected to the cart by an arm which turns a vertical drive shaft centrally located within the cart. This drive shaft is, in turn, geared to an axle attached to two wheels. As the mower moves, it circles the cart, and simultaneously rotates the drive shaft, and hence the axle. The cart is thus propelled forwardly, the mower simultaneously circling or orbiting about the cart. A chute attached to the mower receives clippings, and discharges the same into a receptacle located on the cart. One manual control located on the cart disengages the motive power to the cart wheels. A second manual control disengages motive power to the mower wheels. The mower and cart each have a combination of fixed and caster wheels, to stably and smoothly negotiate terrain.

Abstract: A suspended personnel carrier includes an elevated cylindrical track from which a carrier is suspended for translation by a bearing assembly. The bearing assembly includes orthogonal rollers which ride along the cylindrical track. The carrier is propelled along the track through a fan drive system including a propeller and a motor. The frame of the carrier is divided into front and rear portions connected by a hinge. A crossed parallelogram linkage suspension connects the front and rear portions, such that turning of the front portion by manual manipulation of a handlebar assembly effects a mirror image movement of the rear portion. The drive motor and propeller are coupled to the frame of a carrier by a slip rail assembly, and to the bearing assembly by a shock absorbing telescoping linkage, such that drive force is first transmitted to the bearing assembly, rather than the frame.
