Here is another technology from Plymouth featured in a 1934 PE

A unique, one year only, feature on these cars was a front window frame that had a vent window. When the vent window was closed the whole frame, vent window included, could be rolled down. When the vent window was open only the main window glass rolled down.

1934 Plymouth DeLuxe

EVAP or Evaporative Air Cooler (conditioning)

An evaporator cooler is a device that cools air through the evaporation of water. Evaporator cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. It works by employing water's large enthalpy of vaporization. If I am right the home water coolers(not drinking water ones) work on the same principle.

Anyways, the technology was an after-sale add-on product for cars. It was popular from the 1930s through to the 1960s. The basic unit looked like a canister-type vacuum cleaner. The car coolers were used on antique and classic cars from the Model As to even Street Rods.

To cool the air it used latent cooling of vaporization, in other words, cooling by water evaporation. Water inside the cooler evaporated and in the process transferred heat to the surrounding air, giving in return cool air inside. The lower the humidity, the better it worked. Because of the dry desert air of very low humidity, they were popular in the southwestern United States like California, Arizona, Texas, New Mexico and Nevada. The main reason why it wasn’t popular or even used in India.
They were also popularly known as SWAMP COOLERS due to the odor of algae produced by early units.

Attached are some pictures of the cooler for reference.

Why is this not available anymore? Maybe because of aerodynamics.
This would not work where there is high humidity in the atmosphere.
Our 63Bug has a similar device on his Bug.
In the last picture the car appears to be a nice Rambler, the mounting seems to be crude with a wooden piece for support, or photoshopped.
Can 67 Bug comment how this works? Is only the driver kept cool, or the entire interior cools down?

The Ray Pilot Lamp which is the center light in front of the Plymouth and turns in the same direction as the front wheels was a major fascination for most at the recent Taj rally. It better marques like Dussy, they used to have two lights instead of the single one as seen in my Plymouth.

The first picture shows the light turned in the direction of the front wheels


The center part of the light is the pivot on which the light turns


The marks of Ray Pilot Light are there and we had to be careful not to lose it when we chromed the light


You can clearly see one end of the linkage at the light which moves forward to turn the light right and back to turn the light left


The complete linkage to the steering

Its quite a unique thing, never got a chance to see it in person but looks like it was very thoughtfully engineered.
Thanks for sharing.

All of us are familiar with indicators, turn signals and semaphores. I recently came across some pics and literature depicting a weird little contraption that was developed in the early 1930s and was even sold as an optional fitment on certain early Morris vehicles for a few years.

It was basically a miniature traffic signal with red, amber and green lamps, installed on the front cowl, on either side of the car.

If the driver indicated a left or right turn, the amber lamp on both sides would glow momentarily to caution other motorists, and subsequently the red lamp on the corresponding side would glow, while the other side would be green.
If the driver was driving straight ahead, both sides would have their green lamps lit up.

Understandably, this invention wasn't all that popular!

I seem to recall some very small exhaust fans came as accessories which were fitted onto the door glass frames and automatically switched themselves on when the temperature inside the car went above a pre set figure. Does anyone remember?

Love to know this accessory . Need such a thing for Bombay summers

There are a couple of vehicles in Hyderabad too which have this Pilot Ray Light, and one of them is a Willys Jeep

Thanks! Have seen them on the Bahawalpur RR PII; and always wondered about the details.

Though the single light is more common, what is the rare is the dual lights which come in the high end cars like Dussenberg's, Auburn etc

Here is an example, the Bogilal Auburn V12

The sun shade over the front windshield is a thing of the past. Here is a beautiful sun shade on a 1947 Cadillac which is bodied by Fleetwood. This is unique as it is made of leather unlike the usual metal sun shades

Thanks to Ragtops wonderful thread we are able to witness some fantastic features

The Wheel Balancing process is wonderful in its simplicity

Wheel balancing being done. Each wheel had 3 weight mount caps on it. The process entails lifting off the wheel and rotating it to identify any weight bias. Then I add weights and continue the process of spinning and adding weights until the wheel spins freely and comes to a stop without any bias towards any particular point. It must also not rotate in reverse after coming to a stop. This is a tedious process and takes about 30 minutes a wheel to complete. here are before and after images.

The Hand Brakes system is so unique

Notice the 2 sets of brake liners, the wider set activated by the primary brakes and the narrow set activated by the hand brake. At low speeds when RPM's are low, the brake booster is not very effective so the primary brakes are quite weak, at this time the driver has to rely on the hand brake so it is essential that this is working at its best all the time.

Simple and precise defnition for Trafficators are the yesteryear turn indicators.

They are semaphore signals which protrude when operated, from the body of the motorvehicle and goes back to the grove when turned off.

This videos hows how a trafficator operates.


Trafficators are often loacted at the pillars

Thats a bit of history from Wikipedia :-

They first appeared in the 1900s, when they were actuated either mechanically or pneumatically. In 1908, Alfredo Barrachini in Rome had added electric lights inside the arms, that turned on as they extended, but operation was still by a cable system. Electric operation came in 1918 when the Naillik Motor Signal Company of Boston added electric motor drive. This system was superseded by two French inventors, Gustave Deneef and Maurice Boisson, who used a linear Solenoid in 1923. The final complete system came in 1927 when Berlin-based Max Ruhl and Ernst Neuman combined internal illumination and solenoid operation.
The shape of the Trafficator arm is closely based upon the shape of the semaphore signal arm used by the Royal Bavarian Railway beginning in 1890. The only difference from the railway arm is that it is halved down its length so as to fit flush with the vehicle's exterior.
They were common on vehicles until the introduction of the flashing amber, red or white indicators at or near the corners of the vehicle (and often along the sides as well). They have been increasingly rare since the 1950s, as ever-tightening legislation has prescribed the need for the modern type of flashing signal. Many historic vehicles that are used on today's roads have had their trafficators supplemented or replaced with modern indicators to aid visibility and to meet legislative requirements.
