CONCERT
ROLLER ORGAN
Here
it is.
More photos and info will follow as it's restoration progresses.
If your seeing this and have music that works with this type of organ
commonly called "cobs" for sale contact me.
These wooden rollers with metal pins fit other organs as well like
Chautauqua Roller Organ, Gem Roller Organ and Home Music Box.
20 note "Cobs" play on these machines.
This is all new to me and I am learning as I write this.
The Concert organ arrived,
a little worse for the shipping since the seller on ebay (Andronn)
ignored my suggestion how to protect it.
I suggested the organ be placed in a box then inside a larger box
insulting it from the outer carton.
Instead it was placed on the floor of a single used box with a thin
layer of packing under it. The result was the cabinet split open.
Besides the cabinet repairs, and new glass, it will need all
Pneumatics
repaired.
The mechanism will need cleaning and lubrication including new valve
pads.
Here are some photos of the process.
Here the top covers have been removed. It includes the back cover which
has the instructions on the back of it
There is a cover in the middle which doesn't move and has the painted
"Concert Roller Organ" on it.
Finally there is the front door with glass panel
As you can see it's slightly dirty.
The mechanism has been removed for cleaning, lubrication and pad
replacement.
The cover has been removed to expose the reed block inside, it will be
removed for gentle cleaning
10 reeds on this side and 10 on the other account for the 20 notes the
organ can play
This is what is on the bottom, all of this needs to be redone
with new bellows cloth.
The original bellows cloth is .015 thick, I will use the same thickness
to replace it.
Below are images showing the progress
Here the mechanism has been cleaned and some parts polished.
Old leather felt pads removed.
It has also been oiled , on the right a few drops hit the casting and
will be cleaned.
This is not finished as there will be new pads added soon
While I'm waiting for the Bellows Cloth I turned my attention to the
cabinet
The cabinet has been repaired here, trim painted, and the finish
revived.
I found out that this may be the only one ..so far that did not have
the casting on the crankshaft where it exits the cabinet.
It appears to be a omission by the factory that made it. There are no
holes in the wood where there should be for it.
I have started a search for this part as it is needed to stabilize the
crank shaft at that end. <FOUND>
The funny thing is that it spent it's operating life without it. A
testament to how well the design works, and all for around $7 -$10
Here new pads have been added to the valve arms.
These were purchased from Roller Organ Restoration instead of making my
own.
These are a little tricky to apply. They use a thin film double sided
tape that is very strong.
Once applied its probably impossible to remove the pads without
damaging them.
The originals were glued in place, probably with animal glue.

These are the original Pad parts.
On the left the felt is .1 thick , on the right thin leather with
fabric backing .035
Both pieces glued together than glued to the paddle
I included the dimensions here in case someone wants to make them.
I carefully removed the original bellows material from
the wood surface edges and the glue. This was done by wetting those
edges to soften the glue.
I was able to get it all off with minor damage to those edges of the
material and no damage to the wood.
I did have an unexpected occurrence, when everything dried one piece of
wood developed a slight cupping.
I soaked this wood piece and placed it under a very heavy weight,
checked it a few days later and it flattened out
The 2 black strips of material are the original
reservoir material and (One) of two of the bellows materials
(both are the same)
Those bellows are attached to journals on the shaft that runs front to
back on the top surface of the deck driven when the handle is cranked
The white heavy paper pieces are templates or patterns to help in
creating replacement reservoir and bellows pieces.
Approximately 1/4" was added around the perimeter of the original
dimensions to give a little extra material to work with.
It was suggested to me to cut the deck on this in 2 to make it easier
to recover the bellows, then put it back together with a wood spacer to
account for the cut.
Examining how the organ was made shows that the 2 bellows were made
separately then glued to the deck.
My plan is to recover them without cutting the deck....time will tell.
New bellows cloth installed. This was very challenging. because of how
they originally put it together.
Don't know if I would do this the same way again, I might take the
suggestion I was given to cut the deck and put it back together later.
You'll notice in the middle is a 1/4 dowel this was used to keep
the
material secure to help in the glue drying.
If hot glue was used, I doubt this would have been needed, but a
I usd liquid titebond hide glue.
It gives a bit of time to move things if needed and dries very strong.
Obviously each bellows was done separately after the reservoir. A thin
metal wedge was used with the dowel
on each side to attach the material in the valley between bellows.
Here it is finished.
Not seen in this photo, the top cover stencil was retained
