Russ Huber Posted November 15, 2023 Share Posted November 15, 2023 (edited) Can anyone validate if this Gyro in the ceiling fan category as a National Screw & Tack Co. in the INFO section is a National Screw & Tack Co. product or was it actually a National Screw & Mfg. Co. product? You can see the company name listed on the gyro housing in the image. There is a difference. National Screw & Tack Co. absorbed the Adams & Bagnall Co. in Sept. of 1920. The company name was in changed in 1923 to the National Screw & Mfg. Co. This company name change was implemented on the gyro fixture. I have no validated proof at this time, but it is my impression It was at the time of company change in 1923, or shortly after, the use of the Cleveland based Domestic motors was implemented. The motors seen on this gyro are Domestic Electric Co. motors. Domestic was incorporated in Cleveland in 1915, and their name changed to Black & Decker in 1929.

Russ Huber Posted November 15, 2023 Author Share Posted November 15, 2023 (edited) Here is another SAME gyro example sporting the 1923-27 (AB products division) company name change. Edited November 16, 2023 by Russ Huber Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted November 15, 2023 Author Share Posted November 15, 2023 Self-starting brushed Domestic Electric Motors. That was a key element to Bernie's gyro design, alternating or direct current SELF STARTING MOTORS. 1 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted November 15, 2023 Author Share Posted November 15, 2023 (edited) National Screw & Tack Company AC Gyro fan head.

Russ Huber Posted November 15, 2023 Author Share Posted November 15, 2023 (edited) I see Google book snippet (not a full read book yet) evidence supporting the gyro still possibly on the market as late as 1929. The Adams & Bagnall products division of National Screw & Mfg. Co. name was changed to The Abolite Reflector Company effective Jan. 1st of 28.

Russ Huber Posted November 16, 2023 Author Share Posted November 16, 2023 (edited) This is taking a strange twist. Two engineers by the names of Milton Spielman and Walter Poesse left Frantz Premier Vacuum Cleaner Co. of Cleveland, Ohio in 1915 to form the Domestic Electric Co. also of Cleveland, Ohio. This is the company The National Screw & Mfg. Co. of Cleveland, Ohio got their gyro motors from between 1923-27. In 1915 GE absorbed the Franz Premier concern and renamed it The Electric Vacuum Cleaner Company. Check out these design patents filed for 15 to the Franze Premier Co. of Cleveland, Ohio.

Robert Todd Posted November 16, 2023 Share Posted November 16, 2023 Sort of related. Funny how companies merged, split and changed during these years. This is a picture of my ~1929 Premier Spic Span made by the Electric Vacuum Cleaner Company. I bought it at a flea market many years ago because it has a super long power cord that made it easy to vacuum my stairs. Still works well, but heavy and loud as hell. Original vacuum designs were made by the Franz brothers with the help of Jim Kirby who went on to found a vacuum cleaner company under his own name. 2 Quote Link to comment Share on other sites More sharing options...
Russ Huber Posted November 16, 2023 Author Share Posted November 16, 2023 I stand corrected. National Screw & Tack Co. became National Screw & Manufacturing Co. in 1923. Quote Link to comment Share on other sites More sharing options...

Russ Huber Posted November 17, 2023 Author Share Posted November 17, 2023 Bernie's 1903 introduction gyro fixture. Take a good look, nobody has posted one yet that surfaced. This gyro fixture was manufactured 1903-05. 1 Quote Link to comment Share on other sites More sharing options...

Russ Huber Posted November 17, 2023 Author Share Posted November 17, 2023 The Loren Haroldson named "Weiner Arm" gyro fixture is first seen in 1907 electrical trade and remained on the market it appears until the gyro ceased production. 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted November 19, 2023 Share Posted November 19, 2023 I supposed a similar size motor could be dropped into the shell or a new motor with a variac in the base. 1 Quote Link to comment Share on other sites More sharing options...

Steve Rockwell Posted November 22, 2023 Share Posted November 22, 2023 Another detour off-subject with the Gyrofans... Try this idea, sheer speculation: What if this houses this, and the lower knurled knob controls USD48569 pivoting within the outer shell USD48570 ... The upper knurled knob could be a centering pin for horizontal/level operation... Why else would the strut portion of the guard be so back-swept? What they'd have done, in this case, to power the motor is the next question... but soluble, and unimportant to us now considering there was no such fan produced... until someone finds one..... 1 Quote Link to comment Share on other sites More sharing options...
