Default Patent Idea Display unit

I had a customer bring in a "Patent Idea Display". This had a battery pack inside that powered the headlights (headlight bezels not shown) and featured a rod down the bottom that would oscillate the left headlight, and I believe would flash that headlight as well (based on linkage tied to a relay inside). The control switch is actually the left half of a Model T instrument cluster.















It has obviously had parts (hood) that went missing over the years and an aluminum flashing replacement had been added. He wanted a hood fabricated that looked more period correct, so we offered to do louvers and a faux hinge at the top.


For the hood we used 19 gauge AKDQ, and for the louvers we are using the Diacro press brake. The louver dies weren't tall enough for the Diacro, so an adapter was used at the top to make up the difference.





Our practice punches worked fine, but the machine did not have enough depth to the vertical supports of the press brake for the size of our hood. We would need to get sketchy. Real sketchy.

With only about half of each die in the machine, and two set screws holding on for dear life....

With louvers punched, we used the highly technical argon bottle radius brake to add our hoop. next on the list was to make our hinge using a piece of 1/4" stainless tubing.











Next, our hood needs the beltline bead to match cars of the era, and to simulate the hidden hinges for the hood sides.

Our "hinge" was plug welded in place...








Media blasted for better paint adhesion, and ready for delivery..

I was on a road trip Sunday to pick up bumpers, and since I was in the neighborhood, I popped in and visited the patent display that we made the hood for. The owner has it re-wired and reflectors installed. This video gives a better idea of what it was used for..

Back in the early 20's there were lights that would attach to the bumper and a cable driven mechanism attached to the front steering so that the light would follow the direction of travel. Advantageous for the limited brightness of the headlamps in those days. So this was likely a salesman's prop for selling such a lighting accessory.
