Pressure Atomizing Oil Burner Equipment and Systems – Oil Pumps
Two stage rotary gear pump, with cast and machined steel body, two hole flange and barrel-mount for close, direct motor coupling; with internal pressure regulating and cut- off valves, inlet oil strainer and oil bypass, it would set a new standard for fuel oil pump assemblies, part of a 4th wave in engineering design, characterized by compacted and functionally integrated engineering, Fuelstat, Tuthill Pump Co. Chicago, Circa 1937.
Features: Over coated in flawless gloss maroon enamel, likely to match the colour of an oil burner supplier of the period
Technical Significance:
From the vantage point of the early 21st century, the evolution of oil fired, automatic home heating equipment would be seen as generally advancing in four broad waves, each of which would take place over a considerable period of time, each producing many variations of the genre:
1. Vaporizing, non-motorized and non-electrified, technology [see Group 11.01 artifacts, no. 11.01-1]
2. Elemental, motorized, platform mounted technology with peripheral piping and valving components [see Group 12.01, artifact no 12.01-1, and pump assembly 12.06-1]
3. Compacted motorized technology with inherent, peripheral component parts engineered into the pump assembly [see pump assembly Group 12.06, artifact, and 12.06-2]
4. Functionally integrated, motorized technology, beyond being compacted, a number of functions would be smoothly integrated into a single pump assembly, including piping and valving [see Group 12.01, artifact 12.01-2 and pump assembly 12.06-2]
This pump assembly stands as an example of 4th wave of fuel oil pump assemblies
The close coupled, direct drive configuration used here would be an early application of the design commonly found throughout the industry to the end of the 29th century
Industrial Significance:
Tuthill would be widely acknowledged in the industry as an early innovator in the field, providing many of the engineering ideas, principles, products and breakthroughs which the industry would bill on – see for example ID#271, 272, 273.
