Singer Corporation is an American manufacturer of domestic sewing machines, first established as I. M. Singer & Co. in 1851 by Isaac Merritt Singer with New York lawyer Edward Clark. Best known for its sewing machines, it was renamed Singer Manufacturing Company in 1865, then the Singer Company in 1963. It is based in La Vergne, Tennessee, near Nashville. Its first large factory for mass production was built in Elizabeth, New Jersey, in 1863. - Wikipedia]

1915 - A German-American civil engineer/aviation designer, Frederick Herman Leinweber has grand aspirations in aircraft design, particularly propellers...

1918 - Frederick Leinweber dies, and leaves all of his children his patent rights:








Of particular relevance to this story, Singer Manufacturing Co. buys an American electric motor manufacturing concern to provide domestically produced motors for their sewing machines, Diehl Manufacturing Co.: 
  Philip Diehl (one 'l' in Philip - lawyers misspelled it on at least two patents) was born on 29th of January 1847, in Dalsheim; he graduated from the Technical School at Darmstadt and, like Isaac Singer 50 years earlier, emigrated from Germany to the USA. The son of a physician, Diehl had been a locksmith and in 1868, aged 21, became a machinist (engineer) at the Singer factory in Mott Street, NYC. Two years later, he moved to run Singer's Chicago repair department under James Bolton - inventor of the New Family and the parlour cabinet - who must have recognised an ally in the resourceful young Diehl. His first patent was granted in 1873, for improvements to magic lanterns.  

                                                   Diehl and Miller's treadle ends were the first to bear the Singer logo
Diehl's home was one of the thousands consumed by the 1871 Chicago fire and he lost everything. In 1875, after the opening of the Elizabethport factory, Diehl was summoned - on Bolton's highest recommendation - to take charge of Singer's Experimental Division; later, as Head of Mechanical Construction. 

The new factory was one of the largest industrial establishments in the world, covering a 50 acre site which had four miles of its own railway in the yard alone. Also, the company was expanding rapidly and would be relying on Elizabethport for all the special tooling and machinery needed to equip the new plants in Canada and Scotland.

Singer was a victim of its own success: the more production tried to keep up with galloping sales and an ever-increasing catalogue, the more problems it encountered and the more solutions were needed from Diehl and his staff. Certainly, it is clear that for every 'new' invention they patented, there was another for improvements to existing mechanisms. Diehl held numerous patents for improved minor assemblies and parts. Indeed, in a contemporary report of his most ubiquitous invention, the electric ceiling fan, he was described as the man "who designs shuttles for Singer". By 1880, there had been 75 patents for electrical motors to drive domestic machines but none proved powerful enough to replace a treadle. Eventually, in 1884, Diehl successfully adapted a variable speed D.C. motor he'd recently patented for dentists' drills, and produced the first practical sewing machine motor. On the Singer stand at the International Electrical Exhibition that year, there were "several sewing machines run by various electric motors invented by Mr. Philip Diehl". The first integrated motor was fitted to Diehl's own Improved Family sewing machine. In 1887, in a fit of genius, he bolted blades to this motor, hung it upside down and the ceiling fan was born. That year, Diehl & Company was formed; later incorporated as the Diehl Manufacturing Co.
Ten years later, the Singer catalogue had swollen to 53 different models, comprising 360 different varieties and counting. Sales continued to rise uncontrollably but the factory was now efficient and the boom years had begun - largely due to Diehl and his life-long mission to perfect and create.  In the final years of Philip's life, Diehl Manufacturing Co, needed larger premises but Singer, too, was expanding and commandeered the space at Elizabethport. Diehl moved out; its exports were severely curtailed by WW1 and, in 1918, it was taken over and incorporated as the Diehl Division of Singer. Diehl continued submitting patent applications until the end, with many being granted posthumously. He died in the family home at 528 Morris Avenue, Elizabeth, NJ, on 7th April 1913

1922 - The Leinweber brothers achieve modest success with their helicopter design, but their blade design gets more attention from investors. Is it looking familiar? Hi-Lo Fan Corporation is established with a loan of $200,000.00 dollars

1928 - A young man, Herman C. Hueglin worked as secretary for the Federal Merchandise Company in the Marquette Building, 140 South Dearborn Street, previously working at Commonwealth Edison Co... 








                                                             While working at Commonwealth Edison, Hueglin meets a very powerful and rich man, Mr. William A. Fox, and scores a job as the executive secretary to Fox's firm, the Federal Merchandise Company, of which he is the president and director. Hueglin files for patents for a window fan design, and Fox is intrigued enough to invest in Hueglin, as the company inventor/developer and with Fox as chief investor and president : Here's a correspondence by Hueglin as secretary for Federal Merchandise, connecting him to Fox and Federal Merchandise.:

1928 is a good year for Hueglin. He applies for his first patents, but is listed as an employee of Federal Merchandise Company: 















While Hueglin is the inventor, his boss at Federal Merchandise Company, William A. Fox who bankrolledmanufacturing and marketing Hueglin's window fans through Federal Merchandise Company or through Fox's connections to his former workplace, Consolidated Edison:





The blades for the Hueglin Airmaster exhaust fans are cast solid aluminum, bearing the Leinweber patents (see post 11 in this thread to view the patents themselves:

1931 - Hi-Lo suffers legal issues...

Meanwhile, Herman Hueglin is still working as secretary for Federal Merchandise Company, but he keeps inventing, applying for and recieveing patents for his ventilator fan designs, while president of Airmaster William A. Fox still manages the Airmaster Corporation affairs and marketing...

An interesting anomaly in the Airmaster product line-up: A ten-inch oscillating desk fan manufactured by Chicago Flexible Shaft Company, of which Sunbeam is a Division. The motor appears to be a Diehl. The heavy aluminum blades are of multi-piece, overlapping and stamped construction:  Images courtesy of the Powell Collection: 






Another example, rear view:


Note the cage badge clearly identifying collaboration between Sunbeam Corp. and Airmaster Corporation:

1934 - 


Hueglin and Airmaster Corporation's first pedestal circulator, the Art-Deco step-base: 


A brief side-note regarding Airmaster Corporation and their blade designs for early production circulators; it would see by this example that initial production circulators used Leinweber Bros. blades - Image from the Huber Image Archive: 

Later production three wing Airmaster Corporation circulator blades were still designs help by the Leinweber Bro. To see these patents, refer to post 11 of this thread: 




Diehl 1/6th HP motors were procured to power the single and two speed motors: 



And the two-speed motor with it's "tombstone" shaped speed control housing: 

A quote from the man who owned one - "The 5 motor wires exit out that funky rear bell in the center into the junction box. They are pressed against the back of the inside of the junction box and 90 degree out to the power cord and levolier. The Sardine can cap is held in place by tabs inside the junction. Cardboard is behind it and in front. The levolier HAS to be mounted on the rear cover horizontal as to fit in the narrow slot between the cap and the bottom of the junction box. - Image and description courtesy of Russ Huber]
A close-up of the Singer product capacitor used in the two-speed Airmasters. 


Airmaster Corporation begins marketing it's patented five-wing exhaust/ventilation fans.

1936 - Hueglin's second circulator design, the round leg base, and also his own design owned lock, stock and barrel not by Federal Merchandise Co., but his own Airmaster Corporation:


Example courtesy of the Huber Image Collection: 






The threaded pedestal base very conveniently unscrews for shipping. The previous "step-base" model bases were not designed for disassembly, as the tube pedestal was pressed over the base, and the neck pressed into the pedestal neck.

1941 - World War Two is started when the U.S declares war on Imperial Japan after their sneak attack on our fleet at Pearl Harbor. 

A few days later, Nazi Germany and Fascist Italy declare war on the United States to honor their Axis Treaty with Imperial Japan: 

Hueglin recieves a patent for his two-wing design:

 










Diehl Airmaster rebadged as "Command-Air" for Sears & Roebuck, wood blades replace aluminum as aluminum became a strategic war material during wartime.



                                                                                                                                                                           James M. Funk, designer of Airmaster's 1938 blade design dead way before his time...

1944 - America is still fighting the war, and Airmaster Corporation and Diehl Manufacturing Co. are busy fulfilling government war contracts. Many of the workers have joined up, or were drafted to fight inthe armed forces, while others are sent to specialty schools with an eye to the post-war future:

1946 - People are coming back home to an America of a million opportunities, prosperity and jobs. Diehl Manufacturing Co. and Airmaster Corporation have a record number of old and new employees and positions available. While workers at Airmaster seem happy with no labor or union issues, Diehl Manufacturing Co. employees and their union representatives seem to plague the company with seemingly endless complaints, wage demands, go-slow production, walk-outs and bad publicity. Years from now, the parent company, Singer Manufacturing Co. will be glad to be rid of the Diehl Division in New Jersey, moving production to the American South.

1951 - A very interesting blade material variation has surfaced, mentioned in the Hueglin patent for blade design and assembly U.S. 2542251 - 





 




This Diehl circulator example has factory plastic blades, a scarcely encountered material mentioned in the 2542251 patent, kindly shared from the Welker Collection: 





The circular depressions in the backs of the blades are likely for balancing purposes:





The black plastic blades seem to have a coating of aluminum colored paint simulating cast-aluminum:
