Abstract: A lift for tilting a wheelchair intended for use by a physician, dentist or the like in treating a wheelchair bound patient. The wheelchair lift assembly is portable, light weight and easily adapted to any wheelchair structure so as to provide proper support for the chair and occupant as well as provide the necessary angle of repose. The wheelchair lift assembly generally includes a frame, piston and lift linkage for causing rotation of the wheelchair about its rear wheels and stabilizer bars that support the wheelchair in the tilted position and prevent over rotation. Also provided is a detachable footrest support for the comfort of the wheelchair occupant when the wheelchair is lifted by the assembly.

Abstract: A vending machine for vending flat packages is disclosed which includes vend assemblies which are reciprocal from a rearward position to a forward, vend position. The vending machine is equipped with a rotary coin accepting assembly including a handle, a shaft and a circular cam affixed to the shaft to be rotated when the handle is turned. An activator rod extends forwardly from a reciprocating portion of the vend assembly and includes an operating finger which is positioned to be contacted by the circular cam when the handle is rotated in response to acceptance of a coin. The contact between the circular cam and the activator rod drives the vend assembly to its rearwardmost position to again prepare the vending machine for vending a flat package.
