                                                         MAKING AN ORCHESTRION
                                                                             PART 1

We have a few player pianos that have not been restored and decided to make an orchestrion out of one of them.    First we removed the player parts and fixed whatever problems existed with the piano action.


The next step was to rebuild the stack, eliminating the pneumatics not needed for the 66 playing notes  to be controlled by the O Roll we had decided to use and substituting connections for additional functions.

We obtained a Ragtime roll drive and now we are ready to start assembly.

                                                     NEW SILVERTONE PHONOGRAPH


We recently received a Sears Silvertone floor model phonograph.   The oak cabinet is in good cosmetic condition and the phonograph works and sounds fine.

Since most of the Sears Silverstone Phonographs were made by Columbia, I suppose this machine falls into that group.   There is no model number or for that matter any identification label anywhere that we could find, except for the Silverstone label on the underside of the lid.   From the case design, we suppose it is a 1910 to 1920 unit, but to date we have found no way to be sure of the manufacturing date.    If you have any info about this, please contact the museum at either debencemusem@verizon.net or at 814-432-8350.

                                       REPAIR OF A ROLLER ORGAN             PART 6


We were sent an Autophone Concert Roller Organ for evaluation and repair.

As the assembly progressed, we finally reached the point where we inserted a song and tried it.

It seems that the tangs on the end of the valves that are tripped when the song plays, are very fussy about being properly located.

The adjustments are made by bending the tangs.   When you bend them, it is easy to throw the valve faces out of good closure, so this turns out to be a fussy job.   Not only must they project the correct amount, but they must be vertically aligned to get the notes timed right.



Basically the ends must be correctly positioned both vertically and horizontally and at the same time, the valve face must meet the seat exactly.
