Davis Charlton burner housing
Davis Charlton burner housing
Hello.
I have my first hot air engine which is in need of a heating chamber cover, ie the part that fits over the cylinder end and looks kike a hen coop.
I would be grateful if a member could help me with the height of the cover and also the width and length f the slots in the top.
Thank you
Stuart

Hi Stuart, could you put up a photo of your motor, I've made covers for burners on my motors, but none of them look like a chicken coop.

Hi Stuart !
You should have your engine image, the important of covers for burners: fit outside diameter, length, and height to the floor of heating chamber

Re: Davis Charlton burner housing
You should be able to cut up a tin can to make a cover. First get some cardboard, and make a pattern with that, and when you get that as near right as you can get it, copy it in a bit if the tin can. A lot of tins these days are corrugated which doesn't always look too good. Watch out for sharp edges. You can cut the tin with strong kitchen scissors, but some tin snips would be handy in your tool box if you don't have any now.

Thanks replies
Filed up base and back and brazed today
The baseline of the half circle top is in line with the top of the cylinder,
This gives me an overall height of 2.5 inch for the housing which may be a tad high ?

Re: Davis Charlton burner housing
This is interesting as when researching mine I came across the same engine as yours as being still available in the USA made by P M Research.boydhouse wrote:Same engine but different model number???

As far as I can tell, the Davies engine was only available in the 1950's.
The resemblance is uncanny ?
The DC version measures 7.5 inches long and 4 inches wide - it would be interesting to know the dimensions of the PM model.
Re: Davis Charlton burner housing
PM research seem to have quite a few Stirling Engines of similar design, the others having Pyrex glass hot caps, and glass power cylinder. The PM motor measures 7" x 4 1/4", and I think the flywheel diameter i2 3/4", so the size seems the same, I wonder if the cylinder bore is the same in both engines?

Measurements of my D C engine.
Flywheel is 2 inches, bore is 5/8 inch and stroke is 1/2 inch.
I have now seen three versions of the DC engine where the only difference I can see is in the handrails.
I think the early ones were brass rails with no brass knobs on the end of the rails at the pulley end.
Second type is with steel / piano wire with no knobs.
Third type, like mine, is steel / piano wire rails and cone shaped brass knobs on each rail at the pulley end.

Re: Davis Charlton burner housing
I'll measure mine up when I get home tonight.
I think the plans and probably machinery was bough up by the P M Research. I think we will find they are exactlly the same (with some base and firebox differences.
But the version I have was also made by another before P M got a hold of it.
Mine was made in the 60's by Solar Engines of Phoenix, Arizona.
I know that because I have a booklet that came with it and that is when it was printed.
I also know they (PM) still sellsthis one. Been around for years!!!

Re: Davis Charlton burner housing
On the PM web site the motors are called "Solar Engines" although to run this type with solar heat could take soe ingenuity, but I think where the name came from was the motor with a parabolic reflector, sitting on a tripod, a friend has one he got from the USA many years ago after seing an ad in "Popular Mechanics" magazine.. WHAT EVER, IT'S GOOD TO SEE THESE THINGS KEEPING ON KEEPING ON.
