Isn't this exactly like an XL's system. BRENKERT used this system on their new BX80 Model introduced in 1939. XL's weren't made until 1948...

Looks good though. thx  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 09-17-2014 11:34 PM                        I don't know who copied who but I'll tell you that the Brenkerts I used at the Telluride Film Festival were far and away the most awful projectors I ever had the displeasure of using. Simplexes may not be the best but they were way more enjoyable to use and work on than the Brenkerts.  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 09-17-2014 11:39 PM                     Actually Run # 2 is a better Video and Shows More https://www.youtube.com/watch?v=0MpdgMo27VE You must have run into a couple Beater Brenkerts Joe; still probably one of the most used Brands in vintage Drive-in history!  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 09-18-2014 10:08 AM                     I have never liked Brenkerts especially with very short focus xenon systems they always had a tad of travel ghost When i took over engineering for this company my first task was retireing all the brenkerts replacing them with simplesx ballantyne and cinemecanica  |  IP: Logged Buck Wilson Jedi Master Film Handler Posts: 894 From: St. Joseph MO, USA Registered: Sep 2010 posted 09-18-2014 01:25 PM                     Cool videos! What a neat setup. I had not seen the etched glass Peerless lamphouse topper before, that is beyond classy. Is that a xenon conversion kit or some homebrew of some fashion? Lighted gearbox, too? Nice!!!!  |  IP: Logged Gary Wachter Film Handler Posts: 21 From: Coppell, TX, USA Registered: Jul 2010 posted 09-19-2014 02:59 PM                     I recognized that, it is my guest bedroom (with no space for guests)! That Brenkert clip was recorded right after a complete restoration a few years ago. This BX-100 has a single shutter. I have another one with a double shutter to rebuild at a later date. The Magnarc lamp house was also completely stripped down and redone with a wrinkle powder coat. Even though all the parts were available to run carbon arc, the finish was way too nice to burn up. In its place there is a xenon reflector/lamp assembly from a GE Taleria TV projector re-fitted with a 750 watt lamp from a Navitar slide projector. The Peerless glass nameplate originally light up from a slit on the bottom from by way of the arc light. Now there is a strip of RGB LEDs underneath it to make it any color. Thanks for the comments!  |  IP: Logged Steve Matz Jedi Master Film Handler Posts: 672 From: Billings, Montana, USA Registered: Sep 2003 posted 09-19-2014 08:11 PM                     Very Nice Restoration Gary, A BRENKERT PROJECTOR(BX40)was my 2nd 35MM that I ever saw(after an E7)when I was 6 years old. It was in the 1ST Drive-in built in MT; built back in 1948(only 2 in the state then) In fact all the Drive-in's here used BRENKERT's until they closed in the late 70's. One exception,Our Motor-Vu DI after building this humongous Scope Screen around 54 went to Motio AAA's...  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 09-21-2014 02:17 PM                        Gary, great restoration. Thanks for posting. One question, what are the green and red indicators on the back of the Magarc access door, below the ammeter? The plate between them looks original, although I can't make out the text besides "When Lit" I have never seen this on any Peerless lamphouse. We still use two of them (unconverted).  |  IP: Logged Rick Raskin Phenomenal Film Handler Posts: 1100 From: Manassas Virginia Registered: Jan 2003 posted 09-21-2014 03:35 PM                     I recall seeing them on lamps at the old Jefferson Theater in Falls Church, VA. IIRC they indicated whether or not the trim was aligned. Both lamps would not have been lit at the same time.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 09-21-2014 07:21 PM                     Brenkert was the first with central oil lubrication i the USA. A lot of European projectors had it since the beginning of film. The down side abut BX-80/100 is that unless you have an original factory fiber cone shutter drive gear then the projector is gonna have a very short life span. The gears Wolk made were cut from fiber material that was way too coarse and the gears literally fall apart in the oil. The double shutters also tend to creep on their hubs. The BX-60 is really the one to restore and keep because it uses an entirely different gearing system that is not only more efficient but rarely if ever breaks down. There were Brenkerts all over Chicago and the Suburbs and I never had issues with using short focus xenons. Most had Super Lum-Ex's or Super 80's on them.

The only parts differences are the Shutter pieces used between the single shutter BX-60 and the Double Shutter BX-62.All the Brenkert P.N.s are the same on all the Models and all of them also use the same Intermittent assembly clear up through the BX-100 model.RCA in the 50's converted all the old P.Ns to their System and have no resemblance at all to the old Brenkert P.N.s  |  IP: Logged Frank Angel Film God Posts: 5305 From: Brooklyn NY USA Registered: Dec 1999 posted 09-22-2014 09:22 AM                        quote: Rick Raskin I recall seeing them on lamps at the old Jefferson Theater in Falls Church, VA.

If anyone has the circuit diagram for how that's wired, it might be worth looking into (we still use two of these configured to burn 80amps). I'd be interested in seeing how these worked. I wonder if they'd be any more accurate than the arc viewer projected on the indicator card; that's very accurate, simple and actually quite elegant.  |  IP: Logged
