patent-logo
Today in 1958, US Patent 2863579 A was issued, an invention of George L.N. Meyer, for his “Case Unloader with Bottle Rejecting Head.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a case unloader adapted to unload empty bottles from a case and to reject bottles with corks, caps or other obstructions in the neck of the bottle.

In case unloaders used to remove empty beer, carbonated beverage bottles, etc., from cases and deliver them to a bottle washer, or the like, prior to refilling, much trouble has been experienced with bottles that have been re-capped or which have a cork or other obstruction in the neck. Case unloaders heretofore made had no provision for rejecting such bottles and as a result bottles with caps or corks on the necks were processed through the bottle washer. When such bottles reached the inside brush station, or the rinsing station, the brush spindle, or the rinse nozzle, would strike the cap, cork or other obstruction and bend either the spindle or the nozzle, necessitating stopping of the machine to replace the damaged element.

It is an object of the present invention to provide a case unloader for bottles which will reject any bottles having a crown, cork or other such obstruction in the neck, and so prevent such bottles from going through the washing machine.

Another object is to provide a case unloader which will remove only those bottles from the case which have the necks of the bottles free of obstructions.

A further object of the invention is to provide a case unloader for beverage bottles, or the like, which will reduce break-downs in the bottle washing machinery.

A still further object is to provide a case unloader which will reduce the amount of supervision required to load bottles onto a bottle washer.

A still further object of the invention is to reduce the overall cost of washing bottles.
