Sound Isolating Mounting

The mounting substantially reduces noise transmission between a hopper extension 1 and a hopper 8 for a stack of document cards.

The mounting comprises rubber mounts 4 and 5 on the side of hopper 8 by means of which extension 1 is mounted in shear with respect to hopper 8 so as to allow extension 1 the greatest freedom to move in the X-Z direction. Extension 1 is mounted at the rear of hopper 8 by means of rubber mount 6 which is set in compression in the Z direction by the weight of extension 1 and the document cards within extension 1. Extension 1 is held in location by compression of mounts 4 and 5 which hold the extension in alignment with hopper 8 so that document cards from extension 1 will fall into the hopper, and mount 6 assures that the back of extension 1 is aligned with the hopper back 7. Mount 6 also acts as a pivot to allow the extension to move at the front mounts 4 and 5. Mounts 4, 5, and 6 act as a change of material to cut down noise transmission and also to act as isolation for vibrations of extension 1 with respect to hopper 8.
