US Patent 10106375 Split vacuum elevator system

A Split Vacuum Elevator System has a channel connecting a vacuum elevator cylinder or thoroughfare to an electric equipment housing having motors and valves for the operation thereof. The channel is attached at a top of the elevator thoroughfare through a raised protrusion (or more raised protrusions if there are more then one channel) in a sealing plate that is itself attached to the support structure of the thoroughfare. The other side of the channel is connected to an air buffer known as a collector. This collector has one or more protrusions to connect to one or more channels. A raised lip on the collector facilitates the attachment of the housing thereto.
