Yes, it is a water cooled sterling engine. Now wish I'd said that!!! But I'm just a hobbyist, there is so much information, types and configurations to mention. I just wanted to introduce folks to a great engineering piece of history..... and wish I'd said Sterling engine...

Isn't it basically a water cooled sterling engine?

Thanks Raphael, in all the excitement I forgot the word... yes, it displaces the air. Some displacers are filled with wire wool so the air passes through it as well round the outside. This increases the engine power as the heat is held then released by the wire woold on each stroke. This give more efficient heat exchange. The thing many forget or don't know, is these engines were before petrol engines and electric motors!!! So despite low power, they were the domestic work horse.

"not a good fit" "piston" is called "displacer" I think, lovely machine

That's nice. Thank you George.

When the chimney is fitted it can act as an oil lamp, i.e. the pool of wax feeds the wick and allows the light to be turned up to 2 candle power, unique in candles and candle lamps. I believe they did not catch on as being expensive to make, candles were expensive and the jamming of the wick in the hollow candle (a problem I experience with this one when shut down).

Patented in 1836.

I'm a collector therefore not for sale, perhaps look on ebay...

At least you see if they need oiling...

That's usually the view I like to see too.....

Hot-air engine by Hayward-Tyler Ltd (Rider design) at the Sterling Society meet, Hereford UK. The Sterling engine Society met at Hereford water museum 29th September 2024. Dozens of small engines of many designs, some replicas, were displayed and run whilst the museum ran this original enormous beauty. This 1/2 HP Hayward-Tyler Ltd engine is coal fired and run by the museum on special days.

Nice event. Interesting engines.👍

An original Hayward-Tyler Ltd 1/2 HP coal fired hot air engine also ran. It and a 1 HP engine, both over 7 foot tall are owned by the museum and operate on certain days.

Now make the candle short enough so it fits in the lower casing as a compact unit, and put a wheel and flint striker on the side, and you will see how Ronson Corp. first adopted this idea in 1931, giving birth to the iconic Zippo.

That's really neat.

The patent No is 1318, not as spoken, apologies.

There are many people looking at pop-pop boats and no doubt many experimenting....

Yes, it is pure alcohol so there is no visible flame, which is inside the coils.

Super Teil, brennt die Flamme noch?

Exhibits at the annual LBSC "Curly bowl" competition for model locos designed by "Curly Lawrence". At the Cheltenham Society of Model Engineers 1/9/2024. The competing loco were judged on performance and "the spirit" of Curly rather than fine detail.

Steam fairs and Ebay. Some work on paraffin, but different burners. Best try paraffin first and be sure the cut off valve does not leak and your outside... I've made all these mistakes... Regards John

Where would you buy a naphtha lamp been after one for so long but carnt seem to get anywhere many thanks aaron

hello, do you still have it or similar ones, and do you sell it? Thanks

The lamp would originally have been for burning whale oil, which burners very white. Vegetable oils burning were not as bright and used in cheaper lamps (this lamp was clearly owned by someone of wealth). I love the fact that the design puts the clockwork above the oil. The original Carcel design/patent 1800, put the clockwork below the oil in the font necessitating a seal in the base of the font, with its inherent risk of leakage.

This is an annual event coinciding with the "Festival of light".

This candle lamp is called a Photion, the hollow candle is sprung loaded to ensure it is loaded towards the top to maintain the pool of candle fat, a principle used on the "Palmer" candle lamps of the Victorian era.

Why in the world is youtube... wait a second.

I used to use it at Barbecues, but it decimated the flying insects at night, so on to LEDs

That's the coolest oil lamp I've ever seen.

The power piston is 2 1/4 inch diameter (half the original B4 of 4 1/2 inches. The speed can be limited by adjusting the spring tension on the end of the cylinder. Known for their long life and quiet running.

Rocket model locomotive and tender alcohol fired from tank in the tender. Made .in 1977 for my daughter to fit 2 1/2 inch guage track. Complete with blower, whistle and regulator. Single acting oscillating cylinders exhausting to the chimney.

Mamod ME1 steam engine circa 1960s driving a "3 beer tin" boat. Amazing what you can do when a poor apprentice with - 3 x 7 pint "party" beer cans, 1 gallon oil can, a bean tin, 6 brass curtain rings and a wire coat hanger, all soldered together. During Covid I found it in the loft and added Radio Control and named it UTOPIA. Happy days.

This 1/3 size model if a Robinson B4 Hot air engine. It is gas fired and drives a dynamo to light the lamp. It will also charge the phone... The original full size B4s drove water pumps, sewing machines, dentist drills, compressed air etc.

The pine wood hull is made by drawing round a Bowman SWALLOW hull plus a rocker bottom. The boiler is Bowman and the engine is single acting with brass bevel gears. The radio control is 27 MHz with the servo operating the rudder, not turning the outboard steam engine.

The pivots/joints on the power piston and displacer rods are 6mm silicon tubing.

The hull is bent tin. The diaphragm is 0.1mm brass foil on a 40mm diameter cup with 6mm diameter copper pipe exhaust. Alcohol fired. Very pleasing sound and the first I made with a diaphragm...

The plane is made from 5 Cola cans, double sided tape, 1.5mm wire, super glue and hat pin propeller shaft. All cut with kitchen scissors it is so thin.

It is Radio controlled on 4.2GHz planet 2+2 set up. The batteries are under the seat and receiver and servo underneath the footplate. The control valve is on the exhaust port, tapped 3/16 x 40 me thread. Putting it on the exhaust port is easier than breaking into main steam feed, and any small leakage is not an issue at lower pressure.

Lutz made many zany models, many were steam, but this my favourite, being a stationary flame gulper/licker. I bought it less spring, valve and burner on Eb. Made them and added wheels, axels, funnel, drive belt etc to make it into a mobile.

It is from the 1950s Japan. The hull and boiler as thin as paper and flexes with the fingers!! The name LIBERTY I believe is from the Liberty ships supplied by the USA to Britain during WW2, and named to appeal to the US market. Alcohol fired.

This is 10mm single copper pipe connected to a st steel bellows rapped with copper wire. Alcohol fired (I know...a waste!!!). The hull is polished copper from an old water tank. I later added a radio controlled rudder.

The fan will not fit on top of my log burner, so mounted and converted to run on an alcohol burner. I know, "a wicked waste of alcohol"...

The boat is cooking foil with bread trapped in the back (sorry...stern 😊). No tadpoles were injured in the making of this video...

1/50 PS. 1950s toy, alcohol burner, 200 to 1000rpm. Since the contraction of the flame is 50% of the stroke, the remaining 50% generates pressure which the relief valve expels.

Good

Thanks for the suggestion.
