(back) Subject: Reisner Direct Action Valve question From: "Jon Fick" <jon@VermontFicks.org> Date: Thu, 20 Sep 2001 11:58:28 -0400   We have Reisner Direct Valve Actions in a pair of chests (4' Spitz Principle.) These magnet/pouch combination units default to an open state when there is no wind pressure. That is, the magnet armature falls by gravity and would allow the pouch valve to open if there were actually pressure at the time.   Our problem is the action is sluggish. It closes too slowly on first application of wind (We hear a "chirp" as the valves go to a closed = state.) We can't do any stacatto; the pouch just stays open the whole time. And, the magnet armature drops too soon when wind pressure goes away (We hear a "rippling" and "wheezing" from the pipes.)   The exhaust ports appear to be unencumbered; they're not choked off.   Has anyone ever encountered this? Is it a matter of replacing with newer/lighter armatures?   Thanks.   Jon Fick    
(back) Subject: Swell Shutters From: "F. Richard Burt" <effarbee@home.com> Date: Thu, 20 Sep 2001 11:29:21 -0500   Good Morning: The humidity in north Texas has been very high lately. Our swell and choir shutters have expanded so much they snap shut and then not open again when the swell engine relaxes. As I view the action, the pull rod (tracker???) from the swell engine actually pulls the shutters in an arc pivoting on the weight bearing. As the shutters close completely, they now travel beyond the high point in the arc and the pull rod starts back toward its normally open position. Mind you, I'm speaking in fairly small dimensions at this point. That slight movement beyond the high center point in the arc allows the shutters to "snap" shut. The return spring in that position only serves to increase the tension on the "snapped shut" shutters. This is a relatively new problem. I have not experienced this condition in the previous 10 years. Oh, ...the organ was built by Schantz, just to identify the swell mechanisms. To correct it, I inserted a long screw in one edge of the shutters to prevent them from closing completely. This allows the swell engine and the return spring to cooperate in their functions. We suffer from a slightly louder sound from the closed position, but that is a reasonable trade-off to have the overall swell effects. Check my thinking... When the wood pull rod swells with high humidity, it should extend its length. The situation I described above seems to the reverse of that. Wouldn't the swelled/extended pull rod not pull the shutters quite as tightly as when dryer? Then, there may be something more subtle that I'm missing completely. I think there is a probably a better solution. What suggestions might be forth coming? F. Richard Burt effarbee@home.com

I think most put out 10 to 15 volts, at least the three I have have a bus strip so the output wire can be moved to other screw terminals for different voltages. Might want to verify the voltage as it is right now AT the chest, you = might find it is lower than 12 volts and if so then that is likely the problem.   Randall http://members.aol.com/mpmollerorgan/

In that condition the pull =   rod would then be in a position to open the shades but in the reverse direction than designed. In theory if that became worse, the swell engine would no longer be able = to open the shades because the pivot point is then too far over in the wrong direction and the effect would be to tighten the shades CLOSED even more. From the description and the way I imagine this it's a wonder the engine = even opens the shades at all now but it must be a minute amount the shades have =   gone past the high point of the arc.   If I was there I would first check the felt and then the wear in the shade =   paddle PIVOT pins/holes on the bottom and the top. I will bet you will = find you can wiggle shade paddles in those pivot pin holes due to wear and compression of felt if any in the holes the pins seat in. We use steel ball bearings in the bottom holes, and line the holes with bushing cloth, others may or may not use ball bearings or bushing cloth, = felt etc.   Randall http://members.aol.com/mpmollerorgan/

Direct action valves ... if I am reading his message right, it sounds like he is attempting to use these on a higher pressure than they were designed for, OR it may be that the pouch/pallet size is too large for "small pipe holes".   Could either of these reasons apply Jon?   Hugh
