Recent auction acquisition of a Salesman's Demonstrator (Sample). This gate is included in the category of "Automatic Gates" since it could be operated remotely from a vehicle passing through from either side.
It folds up for ease in transport. The gate probably was enclosed in its own carrying case that is not with the model.
Unfortunately a very important piece of the operating mechanism is missing. The Center photo shows the missing part with a nail in its place. The model is 18.5 inches long, 9 inches high, and the arms extend to 33 inches. The original finish is still intact.
Sept 2013. RESTORED! A machinist friend fabricated the missing parts. The gate now operates exactly as described in the patent.
AUTOMATIC GATE: Patented by Isaac R. Burkholder, of Dayton, Ohio, January 30, 1906, patent #811,371. One half of this patent was assigned to Charles N. Heist, of Cissnapark, Illinois.
