Sioux air tools


 Sioux tools started as Albertson and Co in 1914, their first products being sparkplugs and piston rings, They soon invented and produced a lathe for turning valves, which started them in the tool market. This ad is from 1964 and they're still going strong today. Company history here.

Panther sloper engine cutaway


 




Cutaway drawing by Tony Lofthouse

Panther engine highlighting the drive for the magneto and the automatic decompressor.

One of my vices is Vises (or maybe anvils) A & W

Here's an interesting multi-use tool made by yet another long lost Canadian company, A&W in Guelph, Ontario. The vise jaws are only 2 1/2 inches wide so the whole tool is of hobby size though this thread suggests it dates to the mid 1800s. Wonder what the protrusions along the lower edge of the base are for?

Here's another combination vise anvil.

Airways Special lubricant


Just the thing for your wringer washer. Although it's listed on the can as a Toronto company, they were based in Bradford, Pennsylvania, and are now named Brad Penn.

Oil boiler


 Granville Bradshaw, who had many innovative engine-related designs in the first half of the last century, designed this oil cooled 500cc flat twin in the early 1920s. The cylinders were located inside the crankcase and were cooled by oil splash. The engine was derisively referred to as the "oil boiler" but it apparently worked well enough. He apparently believed the hotter an engine ran, the more efficient it was. Incidentally, this drawing is billed as the first fully sectioned motorcycle engine cutaway to appear in print, the artist's name is not noted and the signature is not clear enough to decipher.

Suzuki resurrected the oil cooled idea with its first generation GSXR SACS engines, where engine oil was circulated by a high volume pump and kept cooled by an oversized oil cooler (radiator). Increasing heat from higher output led them to adopt liquid cooling in the early nineties.

Punch tape computerized accounting, 1964


Baby steps... As late as the 1970’s teletype terminals were still used for computer terminals, especially for dial-up systems. They used paper tape for “high speed” input/output. Computers from that era required a paper tape reader. Imagine loading a software package from a very, very long tape.

 

Monday Mystery; four prong hand tool

  Today's mystery came from an old toolbox full of oddities, It's an all-steel T handle tool with a strange four prong business end. Anyone have any ideas? No markings of course.

Kingsbury Scooter 1919


 Part of the short-lived postwar standup scooter craze, the company was also short-lived, closing in 1921.  Brochure on ebay.

Great moments in automotive history


 

Bessey vise fail

This largely unworn 6" Bessey vise was being thrown out at work. Take it away, they said. The screw assembly had broken so the jaws did not open. The swivel base would have needed to be removed to see what was required, I had no tools handy, it weighs 44 lbs, I don't need a vise project or even another vise. Sadly I left it there. Regrets.

Flying in formation


 Student pilots getting a last minute briefing before going up to practice formation flying. The aircraft in the background is an Avro Anson, a British twin engine trainer.

Wall Auto-wheel penny farthing

 

This amusing ‘outfit’ was entered in a 1922 comic cycle parade at Coventry. Several of these old ‘penny farthing'” or ‘ordinary’ bicycles were entered, but the idea of attaching an Auto-wheel caused the "greatest amusement among the spectators.”

Franklin cars, "The car beautiful"


 

Elliot Bros. micrometer


Here's a beautiful nickel silver micrometer by Elliot Bros. There is what appears to be a sliding button on the barrel which does not appear on the ones shown at Practical Machinist, which has a detailed thread on the company.
 The firm of Elliott Bros was founded in 1804 by William Elliott. In 1850 he formed a partnership with his sons, Frederick & Charles and the firm became known as Elliott & Sons, operating at 56 Strand, London. Whilst their father had specialized in drawing instruments, Elliott Bros offered a wide range of mathematical, optical, and philosophical apparatus. The firm began using the signature "Elliott Bros London" in 1873 and “Elliott Bros (London) Ltd” in 1916. During this time they were located at 449 Strand, London. Elliott Bros (London) Ltd appear to have discontinued producing surveying instruments around WW1 and began to focus on developing electrical equipment.


Thanks, Peter!








 

BSA Starfire


 The tank and sidecovers were also used on the 650 Firebird, to my eye the styling worked better on this bike, the 250 Starfire.  The low pipe model also looked nicer. The advertising company had to work pretty hard to sell these things when the competition was products like the Suzuki X-6 and the Honda CB72.

No animals were harmed...


No matter how suggestive this ad is, animal skins were not used in the manufacture of flour sacks... though the actual material, cotton or paper, seems to depend on when this ad was written, the Lincoln paper mill was also the Lincoln cotton mill.

BMW R25 cutaway


Here's a cutaway model of a BMW vertical single with the focus being on the bottom end and clutch, Why the top end has been removed is unclear, the rod is still in place. It also appears the transmission and final drive has been gutted, The large black lever (below) is the neutral finder but it is connected to the clutch lever.




thanks, Rolf!

Henri Fabre's Hydravion


Henry R Palmer Jr. The Seaplanes, Leonard Morgan Publishing, 1965

On March 28 1910, this unlikely craft, named the Hydravion , became the first aircraft to lift off and land on the water. Although others had experimented, Fabre was the first one to find the right combination of strength, lightness and the ability to break free of the water in the design of the floats. After 5 flights, he modified the craft to a rear rudder configuration and then crashed the it in a stall. Rebuilt, it was later wrecked in a gale. It now resides in the  Musée de l'Air in Paris.
