Abstract
A combination shipping mount and spring suspension system for an appliance comprising at least one suspension assembly which includes a compression spring connected between upper and lower spring mounts. The lower spring mount extends through and is connected to the base of the appliance and the upper mount is connected to the suspended mechanism. The upper mount carries a clip means for releasably gripping a rod which extends through the center of the spring and lower mount such that upon compression of the spring the suspension is placed in a locked, hold-down state. The rod is carried by a member threadedly engaged into the lower mount and is released from engagement with the clip means upon rotation of the threaded member so that the suspension assembly is released to a free state. The threaded member carries a foot portion which is adapted for contacting a supporting surface and may be utilized as a leveling device for the appliance.
