Note that the label specifies this chair is a Congress Pedestal Hydraulic model. Koken developed the barber chair with hydraulic lift and this is a fully functional model.
At one time, Koken was the name in barbershop supplies.
Here's more on the Koken company, its impact on American barbershops and its history in St. Louis, in a report by a local newspaper. Excerpt:

The company was well known and famous for introducing the first hydraulic powered barber chair. Its founder, Earnest E. Koken, held a patent on the chair, as well as many other patents for barber supplies.
