Brown model "H"?

Postby spacebug.049 » Mon Jul 27, 2009 7:59 pm

I have what I believe is a Brown Junior. However, there is no serial number on the case and instead, "H11". I checked Anderson's Blue Book and there was no H11. Does anyone have any idea what engine it is?
Thanks, Hunter

Suggest you look carefully at the bypass on the front of the cylinder to see if there is any writing on it. Your engine may also have a flared end to the intake tube? Is the crankcase sandcast? You may like to have a look at the 1st model Hurleman Aristocrat in the Anderson book. If it is one & it's 100% right then you have yourself a very desireable motor in your hands. A photo would confirm.

Looks like a Hurleman Aristocrat but the tank is wrong.

Yep, very nice & rare Hurleman Aristocrat from 1933. Sadly someone has shortened the intake tube but this could be relatively easily replaced. There's an extra hole in the mounting lug and some other minor "seen use" details. Over all a very disirable collectors engine.

The timer really looks like a Brown timer and so does the cylinder. Was it maybe switched? How much are the Aristocrats worth?

It's definitely not a brown. There were several different versions of the aristocrat in different sizes. They have differnt values. Yours has been hevilay modified which brings the value down substantially. The first came out in '34.

I know very little about this engine. What parts have been modified?

Walter Hurleman designed the timer assy - it's the same as those fitted to the Brown Jr. As to the cylinder - does the top fin have 2 holes in it or none? Is there any writing on the bypass? If not then the cyliner is probably a Brown. However do look carefully in proper daylight as it was etched on and could be quite hard to see - the most obvious mark will be a capital H inside a circle more or less right in the middle of the bypass. I have # H20 in like new condition. Value - depends on if yours is right or not. With the damaged intake & extra mounting hole - if it has the right cylinder then it's $500+ - if not then it's little more than very rare parts so less than half that. Well worth you looking properly then!

It does not have the two holes but I do know that Brown had Hurleman make some engines, the Aristocrats. Maybe they used a brown cylinder when they were short on Hurleman's?

Hi y'all,

I read your post and would like to have some info on a Brown Jr Motor I got from my dad. He bought the motor from an Irish tinker, Paddy Thompson in the late '40's. A propellor logo with "BROWN JR MOTOR" stamped inside the logo, together with BROWN MOTORS CORPORATION PHILADELPHIA are stamped on the cylinder sleeve. The engine mount is stamped MADE IN U.S.A. and the serial number C11310. It is fitted with a wood prop which seems to be handmade, maybe in South Africa. The engine seems unused, as the metal on the cylinderhead is not discoulered from heat like the one in the pic. Can anyone share some info on this engine please? It looks a lot like the one in your pic, "Champion" sparkplug and all.
Regards,
Dusty

1937 Brown C model .601 cubic inch displacement, I believe the basic specs are the same as for the Brown B engine. Please correct me if in error. .875x1.000 bore/stroke, compression ration 6.5:1, approx 1/5 hp at 5200rpm. Hurleman type spark control as opposed to later brown design. recommended prop size of 14 inch diameter by 8 inch pitch.

AMA contests rules cite this engine for models with at least 688 square inches and a minimum weight of 48.1 ounces. Freeflight contest class "c " engine ( this has nothing to do with the c model designation)

Many thanks PW! I had this little motor for many years and eversince remained interested in getting it running. Maybe on a permanent mount or installed in an era model (not to fly though :) ). The engine unit is complete and seems mostly unused. I'll only have to obtain a fuel tank and coil for the Brown C, to power it up. I'd prefer original components if obtainable. My son worked in the USA during 2008. DAMN if only I joined this site then!! He could/might have acquired the necessary parts while there. Quite diffy to reside in Africa viewed from a postage or shipping perspective.

In retrospect of some articles people wrote on this site, I deem that the Brown C guzzles standard petrol/gasoline/fuel :wink: . Not unleaded though. It needs lubricant. Maybe a little more than standard fuel provides :roll: . Does anyone know perhaps what the original designated mixture was, if any?

Nevertheless, thank you all for the info.
Regards - Dusty

Dusty,

The Brown takes the same fuel as other engines of the era and type.
Look in the spark ignition engines forum under "Fuel for spark motors"; there is a lot of info and good comments about ignition engine fuels.

PW,
Great, thank you!
I've already read all the articles you referred to. I'll experiment with the recommended formulas. Well, I first have to acquire a fuel tank and coil. Fookit! Can't wait.

Regards
