Charging Set, 300-Watt Variations

[Bob Carriere]

Hi David

Why is it that all the surplus models we acquired/available in the Ontario area were the British pattern with a cage and mostly converted to 24 volts?????

One of these days I must try to make one run!!!!

My understanding is to make them NATO/ M series compatible. I once saw 3 in parallel set up to run a ground station for helicopter work.

I have several years of brochures (downloaded) - I hope this one works.

The chorehorse was presented as the maid of all labours..light, pump, butter churn, and to charge your radio batteries. Run an entire farm on 300 watts!

This flyer seems to be home oriented, but it would certainly work for a cottage...

The local flea market also had an example of the same unit that we know and love, but in 110v... kick myself for not buying it.

Hi Bob.

I suspect two factors are at play here.

In the Manitoba area, the ratio of these charging sets found with the grill guard setup vs the metal shroud, or none at all, is easily in the order of 4 to 1, or higher, but most, if not all would have been Canadian Pattern Models. Very few true British Pattern Charging Sets are ever found out here. That tells me the Canadian Army quickly discovered the grill guard setup offered better protection for the charging set and vastly improved handling ability for Signals personnel who had to hump them back and forth for remote operations. The latter point is probably one that was not fully appreciated at the start of the war when wartime use of wireless was still not fully thought out. But all this likely prompted a changeover to the grill guard format protection in all subsequent Canadian Pattern Models at some point in the second half of the war, if not sooner.

We do run across 24-Volt units out here (with grill guards) and as Charlie pointed out, most if not all of these, are probably postwar conversions of wartime charging sets to meet the 24-Volt upgrades to the newer generations of Military Vehicles and Signals Equipment.

..... the CMP early gathering at Odessa started out as a small part of the Odessa antique flea market..... there was a collector who showed up with a small flat trailer covered with all possible variety of these small generators.... some military some civilian, some with rope start, some with pedal start....... not a clue who he was.....wonder where that collection is now and whether it will ever surface again......

Nice brochure ! do you have any more ?

[Mike K]

This is a 1936 brochure. The first model appears to have bewn released in 1936 , made in Illinois USA - the "Iron Horse"
I think the Canadian made version, renamed the "Chorehorse" was produced later.

[Mike K]

A post war advert from Australia. Breville manufactured electrical appliances including domestic radios, the brand still exists today. Breville also made military standard multimeters during WW2. The Breville lighting plants may have been army surplus models that Breville badged as their own ?

Another Australian brand was 'Cooper', these were sold as single stand shearing plants and lighting plants.

Go down to your shoe store and buy a Chorehorse !

1937 and 38 adverts for the earlier 'Iron Horse'.

[charlie fitton]

Mike Kelly;Nice brochure ! do you have any more ?

Yes- Yes I do

And to add to the discussion - I think the engine is an Iron Horse - used for washing machines and the like, and the generator is a Chore Horse

[David Dunlop]

Does anyone have a manual with specifications for either the British or Canadian versions of these sets? Just looking through the two OMC manuals I have and realized no weights or dimensional data is provided in either.

In Canadian service, they were part of the C-42 radio sets, which were 24 volt. If you were in an observation post, you could have the chorehorse set back a little ways and with the exhaust pipe slightly buried, it made almost no noise. When the C42 radios went surplus in the early 1980s, the Saskatoon surplus store also got the chorehorses. Some were used, some were still new in their crates with their lend lease decals.

It was my understanding that the ones without cage were intended for mounting on a vehicle (C8, C8A etc.) and the ones with cage were intended to be portable and to be used outside a vehicle, not necessary a difference between British and Canadian pattern (?).

On the left is the Charging Set 300-Watt MK I Canadian Pattern, OMC Model Number CHI-395-4. Note the use of a protective metal shroud over the Control Box

I missed out one of these sets with the shroud a couple of years ago (even though Hanno and I did have a great CMP-border raid that day). In case anyone has one of these shrouds laying around; I am still interested in one for my C8. I do have two Chorse horse sets, but both with cage.

[David Dunlop]

By 1944, the photos and illustrations in the 52-Set Manual and the Truck and Ground Installation Instructions for the 19-Set both have the 300-Watt Chorehorse Canadian as being equipped with the guard assembly.

I would not at all be surprised that as soon as Canadian troops encountered the British Chorehorse in the field, with guard, it proved too popular and the Canadian version was simply dropped. The guard makes picking the Chorehorse up and carrying it, extremely easy, especially if you have just shut it down after a long run. That engine gets hot and stays hot for a while.

.... is to take one down from the barn attic and have a go at make it run....

This tread will be very useful...... David and Jordan stay tuned...!!!!

David,

I will attempt to fill in some of the gaps using these manuals. Collectively they cover CHI-395, CHI-395-1, CHI-395-2, CHI-395-3 (some prior to serial 27590 were designated Mk 1), CHI-395-4 (Mk1 Canadian), CHI-395-5 (Mk1 British), CHI-395-6 (Mk1 Star), CHI-396, CHI-397, CHI-397-1, CHI-397-2, and PU-5008/U (claimed to be modified CHI-395-6).

[Colin Alford]

Weight and dimensions:

The Jan 1945 instructions for the CHI-395-6, and the Jan 1958 handbook for the PU-5008/U include the weight and dimensions.

[Colin Alford]

The improvements for the Mk1 Star (CHI-395-6) appear to be a heat shield between the engine and fuel tank, a thick angled guard ( shield) to protect the bottom of the carburetor and air cleaner elbow, a modified tank with boss to accept carburetor guard, and an improved adjusting mechanism for the governor link.

While the handbook for the PU-5008/U claims that they are modified CHI-395-6, I have observed a number of local examples that do not have any of the CHI-395-6 features, which would indicate that they were modified from early CHI-395 types.
