After scanning images on Google it appears the two motor bells are incorrectly oriented, and the oil cups on this example are not correct.  The bearings appears to have threading for the oil cups present only.

Would my 9" be a Model 36 also?  No Style No. on the motor tag.  This one has the neat square wire struts and I can tell you that it takes two people to pull the cage out to get the fourth strut to line up with the mounting hole.
I take it that your fan came with one complete long oil cup and one top part only of the oil cup but the cup itself is missing?

.I would have to research your 9" model.  Yes, one of the cups is missing. Unless  someone comes forward validating the cups I can only assume based on other examples I googled mine are not correct.

With its introduction in 1904 the Diehl "Universal" desk, bracket, swivel trunnion fan motor was offered in 12" model at any voltage up to 220 VDC, and the 16" model at any voltage up to 500 VDC. NO...mention of the 9" model. 


The first mention in electrical trade(so far) of the 9" model was in ....1908.  It is included with other 12" & 16" " Diehl desk, bracket, and swivel trunnion fan motors as a "Universal" fan motor. No style no. is mentioned. In 1908 all 3 blade sizes of 9", 12", and 16" Universal desk fans were offered in two voltages being.....110 and 230 VDC.


In 1909 it is clearly mentioned in electrical trade the 9" Universal model was discontinued for the new.....8" model.

A very special thanks goes to Bill Arfmann for the courage and kindness to loan me a Diehl ornate base oil cup and top bearing retainer screw to reproduce. To Carlton Ward for our swap so I could obtain the correct Diehl blade and guard. To Kim Frank for his expertise on a fine set of reproduction brass guard supports, with what I might add the "just right" patina.  :D  And once again a special thanks to Mike Petree for a fine new switch lever, and nickel plating my brass brush cap retainers. 


A second year vocational tool and die student removed/inserted new brass sleeve bearings, oil cups and top of cup brass screw in, the Delrin brush holder insulators and caps, and one of the missing brush cap retainers. 


It was worth all the time and efforts to get her all together again. I now have to do the rest.  :D

Russ, sent message regarding the oiler. FYI, Your brush caps are identical to what was used on the DC toilet bowls

I haven't done much for "bringing it back" yet. Thanks to you and the others mentioned I now have that opportunity to do so in the future.  :dude:


These fans are extremely well constructed. A beef cake in the hand so to speak. Grandma would have to get dad to move it for dusting.  :D

Stem bumpers from McMaster Carr.  You can order narrow or wider center hole bumpers.

The old girl has a real healthy commutator with miles to go. There is a car parts jobber near me that has a alternator/generator rebuilding shop. They have a nice old handy size lathe. They will true up a commutator for me for $5. It only takes them roughly 5 minutes to do it.  :D

I never tested the field windings when I found this example. I did a little minor field winding lead wire repair and powered it up. I couldn't be more pleased. The apparatus to the right of the fan is a vintage flea market find. It is a portable DC power source using the old selenium rectifier and a 1.75 Amp variac to control voltage.

The fan runs like new:clap: :D

Could you pull the switches gauge and ohms for each wafer?

Thanks

"Roughly" 82 ohms for medium, 162 ohms for low. I have not connected the switch to the motor to test the fan motor speed yet. Now you got my curiosity up. You see what you make me do. :D

Tested and approved.  Three distinct speeds. :clap: :D  If you want a real sweet bedside low speed add a few more ohms to the second wind.

Here you go.....

A whopping 1950-2000 RPM on full rectified wall current.

1550 RPM medium speed.

1215 RPM low speed. 

I would give the low speed a few more winds to tame her down to roughly a 1150 RPM 6 pole AC induction motor residence fan motor speed.
