If it's Jetcone and NOT a Bendix, then the pope CAN'T be Catholic.

EXCEPT:

Unfamiliar with a Benny capable of 16##, whereas a Whirly Combo could take 16 (guessing, since the tub is huge) and since the Whirly could barely squeeze out Gladys's non-electric blankie/ bed/rug--205 rmps.......hmmmmmmm.

Because of the use of radio tubes, I'm guessing RCA---Whirlpool. Radio tubes, however, were slow to react to commands so I'm wondering how this thing would have worked. I guess Philco could also be a possibility given their prowess with radio and tv technology. Was Bendix owned by Philco at this point?

Quick Cycle

Because of the 28.1 second cycle advance, resulting in a fairly short cycle, and the 16 pound load..

I will say a Commercial Laundry Bendix Front Loader.

Although I don't see a coin box.

After I got into bed, I remembered that it was the Bendix that left too much water in Gladys' bed; the Whirly was used for the white load, the better to heat it.

Today, the soap dispenser shouts Bendix.

The whole idea of a Time Delay Relay based on a Vacuum Tube is quite interesting though. I wonder what tube they used, was it a standard radio/tv tube at that time or was it something special made for Bendix -- or whoever :)?

How did this circuit work exactly? Was the delay caused by the tube heating up and once it was hot enough (heated by the internal tube heater) it would energize the AC solenoid directly? So would the AC line be wired into the plate side of the tube and the electrons would then be conducted onto the cathode side and into the spin solenoid??? I'm Confused and MUST KNOW! LOL.

Relay tube...

I think that the tube is not an electron tube but merely a housing for a relay switch. In the first picture you can see the switch contacts in the tube. Maybe the delayed switching is caused by heating a bimetallic strip or something similar.

You know, I think you are right Theo, now that I take a second look. I have relays that look like that but are in a square housing. Besides if it were a common vacuum tube the heater has a voltage requirement of 6 or 12 volts depending on the tube type. So that would require a dropping resistor onto the 120volt line to the heater which I don't see mentioned in the text.

Hmmmmm oh Jon.

Yup, that's it, it looks very similar if the not the same in the first picture!

This explains the lack of dropping resistor on the heater voltage:
Contact voltage rating 115V
Contact current rating 3A
Heater voltage range 90 to 130V
Contact type Normally open
Delay 30s

all the Smart Bendix guessers!

Here is the front panel

And yes the vacuum tube in question is a bimetallic thermal relay housed inside a vacuum tube!

I am told they were used on other Commercial washing machines as well.
Mielabor you have a very good eye!
This machine was the 1956 model and was a Bendix hybrid! It combined the cabinet of the Gyromatic with the guts of the Combo all bolted down like the pre war machines and it had the removable panels of the original Gyromatic from 1948! A real mix up!

Heater voltage?

The heater voltage would be the least of the problems. Consider the plate voltage! 400V and water tend to not get along too well...

No problem with water and 400 Volts, most commercial washers work on 400 Volts overhere.

No if its a

115NO30 Amperite Tube then the top voltage is 130V See below from the Chart.

SO with this tube since its not exciting electrons to leave a surface only heating a strip it does not need 440 whompin Volts! YAY!


Contact voltage rating 115V
Contact current rating 3A
Heater voltage range 90 to 130V
Contact type Normally open

I wonder if this tube has a true vacuum or it's just sheilded by the glass wrapper and uses a tube base that was so very common back then.

That's what you get for not blacking out the model number Mister.

Those thermal delay tubes are quite fun to play with, used most often as a delay for B+ application or industrial control. I have a box in the basement just waiting for future projects and they can still be had NOS for the right price.

I must have missed what it's used for in this washer... Anyone??

"Relay Tube"Really just a relay-but in a vacuum tube enclosure-these were VERY reliable-since the contacts are not exposed to air-these would last for a very long time.Have found them in transmitters-as filament to plate time delay relays.It is used in the transmitter to prevent you from energizing the high voltage plate supplies until the filaments have warmed up-typically the TD values were 30sec,60 sec and 120 sec.Interesting to see one in a washer!

Did Bendix sell the rights to Dexter? The early ninties Dexters look remarkably similar. The frame and tranny look identical. Was Bedix loud and unreliable too?

Loud Yes, Unreliable??? SLAP!

jetcone's profile picture
What happened Bobby was this machine was made by Bendix in 1956. In 1957 Bendix was bought out by Philco. Around 1958 Ford bought Dexter. Merged Dexter & Philco under its appliances. Dexter took all the parts and molding to their molding shop in Iowa and started making the commercial machines, which as you pointed out were made right up to the 1990's. So most of the Bendix Combo parts are still available new from Dexter. Pumps, solenoids, tub seals, motors and tranny sets, cointraps.

A stroke of luck for us Combo nuts I can tell you.

So I am guessing this would be a pretty rare bird of a machine since it was only made for a year. Anybody ever see one??

I have seen "Dexter" machines go for years in a laundromat. What is your experience that has led you to see them as unreliable??


Post# 227010 , Reply# 48   8/2/2007 at 11:26 (6,083 days old) by bobbyderegis (Boston)        

Jon,
I got five "triple load" Dexters from a laundromat in Everett when it closed. There was only one with the tranny that shifted from lo to med to hi as it should. The rest leaked oil, and the clutches and shifters were mangled to hell. I hooked one up, and the motor burned up soon after. I bought a completely new motor and tranny assembly from Dexter, and it shifts roughly, and makes these grinding squealing noises occationally that will make your hair curl. I have spoken to several techs at the factory and they are all clueless. Do you have any ideas? I'll give it this: it's built like a tank.
