Expando combined bar & coffee table

This if from my mom's estate, other than the patent we have not been able to find out anything else about it, I took a pic of the table collapsed but can't find it, will post a pic when i can get back out there. You can see the bottle racks on the backside. Really cool piece, collapses down to coffee table height. It was patented in 1955 and assigned to Abco Metal Products Co, Hawthorne, Ca, can't find anything on them either. Anyone ever seen one of these? See patent below:
