As part of an inventory of equipment that would be installed when the Laff In The Dark ride was delivered from Chicago to Rye, Traver forwarded a stunt list that described an incredible 29 tricks, 36 if one counts the "seven floor stunts" listed as number 1. Further, the list does not include the Gorilla and Fighting Cats stunts that were installed in the Playland ride.

Now, with the perspective of Traver's patent drawings, we are privileged to take a rare trip back in time to walk through and view an original Laff In The Dark ride as it operated at Rye Playland around 1936.

in 1934, prior to the widespread application of pneumatic cylinder systems in dark rides, Traver devised a variety of mechanical and electrical apparatuses to impart motion to his stunts.

In this example, the skeleton figure was suspended by two springs with an incandescent light fixture overhead (fluorescent ultraviolet light was also still in the future). Viewing the base of the skeleton as shown in the enlarged inset, a large vertically-mounted solenoid can be seen situated on an elevated block. The unit consists of a cylindrical winding into which an iron shank, linked by a wire to the skeleton's torso, is suspended.

To activate the stunt, a voltage was applied to the winding and the shank was drawn electromagnetically into the core, pulling the figure down with it. With current delivered intermittently, the skeleton would jiggle.
The effective core stroke appears to be approximately 2 - 3 inches.

This barrel still exists in the ride today although no longer rotating. A lion waits in tall grass at the exit end. Stars are applied to the barrel walls, but were probably not pre-lit to glow in the dark when a car entered. Such an effect was used in the
Laff In The Dark at the former Euclid Beach Park
in Cleveland, OH, an innovation credited to the Humphreys,
owners of the park.
