Author Topic: Changing oil in first generation Devry Jacob Delaney Film Handler Posts: 23 From: Rancho Cucamonga, California, USA Registered: Dec 2014 posted 10-03-2015 03:22 PM                     I've got an old beat up Devry 35mm projector with a SN of 150 (not sure what model it is) and I'm trying to figure out how to properly change the oil of its intermittent. I have been able to take it apart slightly and let some oil drain but I really don't think that's a good idea. Here's what it looks like I circled where the oil cap is but the only way to get oil out of it is to take the whole thing apart and shake it upside down and even that doesn't get the oil out of there. Also, it's impossible to see how much oil is in there because there's no oil window.  |  IP: Logged Robert Koch Film Handler Posts: 93 From: Williams Ca USA Registered: Apr 2006 posted 10-05-2015 10:21 PM                     You have shown the wrong side of this insult to engineering. Most of these had a cheaply made imitation of a Simplex movement. You should take the lower screw out of the movement on the film side and let it drain overnite this, providing some moron hasnt filled it with sae 90 or something like cup grease My advice to you, find the nearest body of water close to your residence and throw this damn thing in it.. g  |  IP: Logged Jacob Delaney Film Handler Posts: 23 From: Rancho Cucamonga, California, USA Registered: Dec 2014 posted 10-05-2015 10:33 PM                     Robert, I only got this projector to mess with. I have a newer Devry modified by Kodak for dailies and a Wenzel. Both of those use Simplex intermittents. I was able to take the bottom party off from the screws down there but since so little came out I'll try and leave it open overnight like you said. Thanks Here's the operators side: The outer casting looks like cheese or plaster wall  |  IP: Logged Steve Kraus Film God Posts: 4094 From: Chicago, IL, USA Registered: May 2000 posted 10-06-2015 08:46 PM                    I never did figure out how the DeVrys knew I was running a loop so it could quickly shred them while running an actual reel was okay.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 10-07-2015 03:15 PM                        quote: Robert Koch You have shown the wrong side of this insult to engineering. Compared to a Monee or a Spectra, it's a paragon of industrial archeology. quote: Robert Koch My advice to you, find the nearest body of water close to your residence and throw this damn thing in it.. Given the drought in the Inland Empire, that would probably mean a trip to Santa Monica. And the chassis is probably made of such thin and cheap steel that the chances are that it would float.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 10-10-2015 04:23 PM                     Dailies? No one runs filum dailies any more... I guess that's why you have it then.  |  IP: Logged Robert Koch Film Handler Posts: 93 From: Williams Ca USA Registered: Apr 2006 posted 10-11-2015 10:23 PM                     Steve Krause: Ive been there; why do you think I have the hatred of these damn things. The navy cost the taxpayer, during the war, a bundle, thanks to a clandestine meeting between a navy purchasing agent and some Devry sob who paid this navy bastard plenty. sob  |  IP: Logged Jacob Delaney Film Handler Posts: 23 From: Rancho Cucamonga, California, USA Registered: Dec 2014 posted 10-12-2015 01:14 AM                     Mark, Kodak modified them in the late 50s and early 60s I think. It features a magnetic interlock as well as optical sound. It also has a xenon color filter for the tungsten lamp. all of it is on a cart type base that you can easily cart around. The whole thing weighs about 250 pounds.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 10-12-2015 03:02 AM                     Thought the Ballantyne PRO 35 was the desired candidate to anchor a boat down to keep it from drifting away... and their INT assemblies were the absolute pits to work on! I trust that Jacob had never had the privilege to operate and maintain such a device.  |  IP: Logged Frank Bolkovac Film Handler Posts: 27 From: Monroeville, Pa.

If it's a hardened star and cam running in cast iron bushings then a light projector oil. I If they are soft steel star and cam like Brenkert then things may need to be very different from the norm so you don't ruin the internal parts. Motiograph for instance used grease in their movements. I will take a Christie any day over most projectors! If they are maintained properly they actually need very, very little maintenance.

All of their other film equipment like their loop boxes (whatever they were called) were custom made for attractions I think. The oil that came out of it was watery and very dirty so I was just going to put Simplex oil or 10w non detergent compressor/hydraulic in it, but who knows if what was in there was correct. I almost got a PRO 35 a couple years ago but thanks to this forum I found out they were no good  |  IP: Logged Jim Cassedy Phenomenal Film Handler Posts: 1661 From: San Francisco, CA Registered: Dec 2006 posted 10-12-2015 04:22 PM                     I had one of those DeVry's many years ago. It was noisy, the image a bit unsteady and not that gentle on film. I never considered the projector itself to be a 'boat anchor' (and I had actually had a boat back then) but I definitely would use that term to describe the DeVry amplifer! It was built like a tank- - with a couple of huge, heavy power and output transformers, plus some big heavy iron inductors. Vacuum tubes, of course. ( 5U4, 6L6's and a couple of others.) But mostly, I remember it was very HEAVY and it put out enough BTU's to heat a small room. I recently came across some patent documents which showed a Bell Labs patent application from 1928 for a 35mm "portable talking picture projector", and from the drawings, it looked remarkably like a clone of the DeVry. (Or maybe DeVry cloned theirs form Bell's)  |  IP: Logged Jacob Delaney Film Handler Posts: 23 From: Rancho Cucamonga, California, USA Registered: Dec 2014 posted 10-12-2015 05:37 PM                     Is this the same one you're talking about? "Model 389 power amplifier 75 watts" The other half is a controller for sound, treble, bass, and mag/optical/mike. It worked a little bit when I first got it but it just slowly faded away until no sound came out of it. I noticed a resistor was fried and some of the capacitor's labels fell off so I couldn't fix it and replaced it with a CP-55 and a spare QSC 1400.  |  IP: Logged Sam D.
