Photo Cabover Phoenix Log Hauler (Circa 1922)

Hello folks,

While working on some research I stumbled upon this amazing machine in the January 7, 1922 issue of "American Lumberman"

Its well known that Phoenix produced steam log haulers based on the Nov. 1900 Lombard patent which they were licensed to use. We also know that around 1914-15 they attempted to market a gasoline version which was later offered in modified form by Allis Chalmers.

What I did not know is that Phoenix had tried to produce a advanced steam design as late as 1922!

Here are the specs (note the use of compound engines, condensers and an advanced boiler design.)

Source: The Phoenix Road Locomotive, American Lumberman
January 7, 1922, pp 68 & 69

Boiler pressure: 400 psi

Steam chest pressure:300 psi @ 25% cutoff (super heated)

Boiler: Drumless sectional water-tube boiler designed by W.H. Winslow (Winslow Bro. Co. Chicago, IL.)

Burner: Blast type (oil, low grade distillates)

Condensers: Under normal operating conditions the water lose per gallon is equal to the fuel burned.

Weight: 8-1/2 tons

Capacity: (deck load) 5 tons

Drawbar pull:(normal) 2,500 lbs @ 6 mph

Drawbar pull: (Maximum) 5,000 lbs @ 6 mph

Wheel base: 10’-6”

Engines:(2) 3-1/2x7”x5” (compound)

Brake horsepower: 60 hp @ 25% cutoff

The article optimistically states: “Orders are now being tentatively accepted for these road locomotive – deliveries scheduled for the spring of 1922”

Apparently like the gasoline tractor this machine used a track design by C. L. Tolles (Pat. 1106595, Nov. 1, 1912) that is based on the Nov. 9, 1900 Lombard patent as previously used by Phoenix.

W.H. Winslow patented quite a number of boiler designs. Since the article stated it was a sectional water-tube design that had 10 years and $150,000.00 of development behind it I assumed it to based on this his May 1921 patent.

Makes you wonder if the prototype was ever completed and if so how many others were produced.

Best regards,
