today I started tearing apart my 1935 terraplane

and under the back seat was a factory made hole in the floor

about six inches round with a kind of bag hanging down between the

floor and the road. Can any one tell me what this was for??

    It was an air vent and the bag was a sort of filter. It had something to do with the way the air moved through the car due to the vent windows. I don't recall that it was a 6" hole, though. I thought it was a series of smaller holes punched in the floor, like a grille.

    Jon is correct, the "bag" is suposed to be a filter that stops dust entering the car. The principle ( theoretically) is that with the vent windows open it creates a negative pressure within the car, which draws fresh air up from under the car, and circulates throught the passenger area, and vents out the open windows. Of course what happens on dusty roads as we all know is that the filter gets totally choked up, and as much dust enters the car as is filtered out! Plus what about all those nasty fumes hanging round at road level? I still reckon the "vintage" era cars have the best ventilation of all, with the cowl vent, and opening windscreen, that is until you fly through a swarm of bees or wasps! An amazing feature of the Step-down bodies is that you can have the front vents open, and the window right down, and not get a blast of air in your ear, a feature which unfortunately they lost with the Jet. You have to have the window only half down, or you get blown out of the car in the Jet.

    I had a local seamstress make a faithful reproduction of this item for my '36T and it is installed in the car. There is information about this feature in the promotional material for 1936, I didn't realize that it was on earlier cars. I thought that it was another of the "one year only" features of my '36!

    Richard, I didn't take time to peer under the Hornet, but our '47 has the "bag filter."

    Park, the only bag under the Hornet would be the one you picked on the highway that says 'Wal-mart' LOL.

    I had an air bag in 1949 Chevy coupe I owned at one time - I divorced her.

    My '41 has one right above the rear end... someone told me it was also used to relieve pressure so that you didn't have to slam your doors to close them... I don't know about all that, I believe to help venting is probably the real answer...



    Maybe someone can post the literature on this... not that it's top one my Hudson trivia list, just interesting "facts" :confused:

    My '33 Terraplane Coach has the opening under the rear seat - It's approximately the size and shape of the radio speaker grill on the step-downs, and had a material cover attached to the edge of the opening. And, as mentioned above, the cover must have soon become clogged with dust and road oil, because I'm sure not much ventalation was provided by the cover in my car.

    The "Weather Master" info in the 46 owners manual shows the fresh air coming in thru the cowl vent and EXITING thru the holes under the rear seat. the cloth was just a dust filter.
