Identify these bikes! / Re: 1920s Bike Needs Identifying....
« on: January 03, 2008, 05:30:59 AM »
A good plan might be to apply the magnifying glass to the original print of the third photo: the script on the tank looks like it could be readable.

I wonder if it might say Connaught?

Identify these bikes! / Re: Strange Bike II - What is it?!?
« on: December 01, 2007, 07:59:13 AM »
Hi Mario,

I think we're agreed that the front fork is Puch, so now it just comes down to identifying the rest of the bike.

With the better photos, it now seems stranger than before!

Correct me if I'm wrong, but it looks like the motor drives by chain to a countershaft, then on by another chain to the rear wheel. What's on the end of the countershaft? Is that large disk just for the generator to drive from? Or a clutch?

The back wheel looks interesting. Perhaps it has a clutch, or even a 2 speed gear inside? This fits in with the little I know about Puch. There is the remains of a c1912 model R2 here in Australia, which is similar to the Model N but has chain drive and a 2 speed gear in the rear hub. I have also seen an early 1930s Puch spilt single that has a "normal" gearbox, but has its clutch in the back wheel. Obviously Puch liked complicated rear hubs.

And isn't that another sprocket I see on the right side of the rear hub? For a pedal chain? If so, the hub could be pre-WW1.

To me, it is the frame of the bike that looks very strange. What are those lugs on the seat tube? If you look closely, does it look as if it has been altered?

And the motor? I'm not sure. I doubt very much if it is pre-1910, but it could be just pre- or post-WW1. Is it Puch? You might have to find a Puch expert to sort that out!

Here's my guess: I suspect the bike started out as an early Puch, and was heavily modernised (say in the 1920s) to lower the seat height, incorporate the generator, and generally make it look less antique.

Keep searching for info, Mario, you've got something very interesting here!

I'm not sure of what the bike is, but I've seen the front forks before: they are identical in layout to those used by Puch around 1912. I'll stick my neck out and say that the forks are either made by Puch, or made by the company that supplied Puch.

The problem is that the bike is obviously much later than that - perhaps early to mid 1920s.

Was there a Puch that looked like this? Or perhaps another Austrian manufacturer?

Best regards

Identify these bikes! / Re: Help needed - I think it's unusual!
« on: November 13, 2007, 12:58:47 PM »
Hello Pat and Rich,

I agree - a most unusual machine, and almost certainly an NSU.

Note that it's a slightly different model than the one shown on 3wheelers.com. While that one has the 2-speed gear and clutch in the back hub (perhaps a ROC hub?), the one here has the NSU 2-speed gear and clutch on the engine pulley. The gear is operated by the vertical rod passing through the "N" on the tank to the little tram handle on the tank top. Wind it one way for low gear, then the other for neutral and then top.

Regardless of the exact specs of the machine, it's a most atmospheric photo! Thanks for posting it.

Hi Beakster,

It's an Indian "Standard" of 1922-24.  1922 was the first year of the bigger mudguards with flat stays, and 1924 was the final year of production.

Prior to 1922, the model was called the "Powerplus", but in  1922 the Chief took over as the Indian big-twin flag ship.

Thanks for the positive comments - I'm please you enjoyed looking at the website. I designed it for a leisurely browse.

Just to finish off with this photo. I checked the registration records and 11816 was issued to H.K. Scott of Currency Creek (a rather isolated spot about 80 km south east of Adelaide) in June 1918. By then the bike was about 7 years old. Plenty of time to do those sporty mods!

Yes it certainly is, but a much-modified one.

It looks like it started out as a 3 1/2 HP (500cc) water-cooled model of the type current between late 1910 and 1912. The registration number was issued much later, so at a guess the photo might have been taken after the war.

Modifications are the valve enclosure, footboards instead of the usual pedals, extended air intake on the carburettor and the dropped handlebars. Magic!

The engine is a Precision (made by F.E. Baker Ltd. in Birmingham) and the frame is made from Chater Lea fittings.  On this model the radiator occupies the front section between the tank rails, and is separate from the fuel and oil tank behind it.

Lewis built probably 2000 machines in Adelaide, South Australia between 1899 and the mid 1920s. For more information check out The Lewis Project website:

If anyone has Lewis photos or information, I'd love to hear from them.

Cheers

Identify these bikes! / Re: Unknown 1930's single....
« on: September 02, 2007, 06:29:24 PM »
I think if Murray gets a bright light and a magnifying glass he might read "New Hudson" on the tank.
New Hudson went in heavily for the enclosed look in the early 1930s (lots of pressed metal enclosing the lower half of the motor and gearbox) so I suspect this example is from the late 1920s. Probably a side valve 500 from about 1929?
It's a handsome bike - a pity about the antiquated carbide lighting set!

Cheers

European and Other Bikes / Re: Felix Millet 1892
« on: February 27, 2009, 12:47:23 AM »
Hi Tim,

Thanks for asking what is the most interesting question I have yet to see posted on the internet!

Of course my initial answer is "no idea", but there are ways... Despite the 1888 patent date suggested on the link you provided, the only Millet patent I can find in a quick search is Swiss patent CH9899 of 21 January 1895, granted to Felix-Theodore Millet for "Une bicyclette a roue automobile". The patent is very detailed, with 18 pages of text (in French) and 14 detailed drawings. Great stuff!

The motor is in fact fairly conventional - at least in the sense that it has poppet valves for the inlet and exhaust. The exhaust valves are driven by a fixed cam in the usual way. The exhaust pipes run down the spokes to a collector around the rear hub, thence forward to the carburettor amidships. Here the hot gases spiral around the carburettor to preheat the inlet gases and better vaporise the petrol, before exiting via the exhaust pipes labelled g and g' on your posted drawing.

The patent is a must read if you want more info. It is available online at the European Patent Office: on the advanced search page http://ep.espacenet.com/advancedSearch?locale=en_EP just type 1895 in as the date and millet as the inventor and click "search". Let me know if you have a problem getting it and I will send you a copy.

Now my question for you: if you're not a vintage biker, why the interest in Millet's marvellous device?

Cheers

Leon

Hi all,
What a fascinating hobby we have - almost an infinite amount of hardware to contemplate - consider the range manuacturers around the world at different times, then add in the backyard fiddler who modifies this and that to suit needs or preference. Personally I like looking at old bits, photos or whatever, and it's particularly satisfying when we learn something from the exercise.
I wonder should we revisit some of the thoughts in this thread?
Our original poster Peet_K asks what he's got, posting a clear photo and telling us it has "New Hudson" on the seat. Peter C replies "It's a Triumph C-Series frame (Models CN, CO, CSD, CTT) from 1929-32." This sounds pretty defintive - Peter tells us the frame IS Triumph, no ifs or buts. He doesn't say "highly modified", "slightly unusual" or anything like that.
Our original poster, probably having been to Peter C's web page where the C model is described http://users.actrix.co.nz/cornelius/Triumph/ModelCN.htm , notes that it doesn't look too much like any Triumph that he has seen, and posts some more pictures (interseting punch set used for the frame number!). ColinB seems unhappy that the triumph specialist could be doubted (and asks Peet_K what he thinks it is - he doesn't know, that's why he posted!), and m3bobby states uncategorically that "its definatly Triumph" but explains the major modifications where the frame has been cut and shut.
Peter C. finishes off with "it's now a Nothing frame, and worth the same amount", which seems quite a shift from the previous day when it was a Triumph C-Series from 1929-32.
I wonder where this leaves Peet_K? Has he learned anything? Have other forum mebers learned anything?
Unfortunately I don't know a lot about early 1930s bikes, but  I do know that the frame is quite unlike the Triumph C-series frame as shown on Peter C's webpage, but perhaps Peter C or m3bobby can tell us more. As to being worth nothing, quite the contrary! Good bits here, if only we can identify them.

British Bikes / Re: 1912 Rover
« on: April 26, 2009, 11:05:11 PM »
Hi Daimon,
If it has been sitting in the dry, and it was running before it was left there, there should be no problem in starting it. I'm happy to give instructions, but first we need to know what the drive arrangement is. Because it has a side-car, it will likely (but not necessarily) have a clutch and gears of some kind. Later Rovers can have a gearbox (chain from engine to gearbox, belt to the back wheel), but in 1912 it would more likely have a clutch and gearbox either (a) in the drive pulley on the engine shaft or (b) inside the back hub. If (a), it probably has a little tram handle control, or (b) will have a foot pedal clutch and a lever to select the gears (if there are any). If it's something else, you might have to post a picture. Let us know.

British Bikes / Re: Albion Gearbox .........Unusual project!
« on: February 25, 2009, 09:07:13 PM »
Hi Rod,
To give you some idea, an 8 h.p. (say 1000cc sidevalve twin) motor in an early motorcycle would be geared at around 4:1 (4 turns of the engine for one of the back wheel) in top gear with wheels of rolling diameter 26".
Your proposed 14/42/14/42 gearing would give an overall ratio of 9:1 in top gear (1:1 in the gearbox), so it would be very low geared. But then you have to carry around 3 wheels, and the B&S might turn higher revs than an old twin. Some experimenting will be required!

British Bikes / Re: amac carburetor
« on: February 15, 2009, 12:06:38 AM »
These days old carburettors are often built from slightly mixed collections of parts, so we have to do the best with what we have!

My AMAC book gives model T. 15MDY and T. 15MDX as 1928 touring models with bottom and top feed float bowls, respectively, so maybe the "4" you quote is a mis-read of X or Y? Equivalent 1926 and 1927 models are PJY and PJX. "15" refers to 1 1/8" throttle valve - sounds about right for a sv 500.

Anyway, the plan should be to get the fuel level just below the top of the jet. From your description it sounds like this can be done - even if you need to modify the notch on the float needle or the clip on the float. An easy check for about the right fuel level is that the carb shouldn't drip if the bike is upright, but begins to drip if the bike is leaned over away from the fuel bowl. Test this with the throttle open (no needle bocking the main jet) but the engine not running!!!

Hope this helps. I can copy the parts list, but I doubt it would be of much use.

Sorry - can't help with the fine detail. You might find an expert who can, but with three magdynos in front of you you might have more info to hand than can be found easily (or reliably) in books. Set aside an evening on the kitchen table!
