You may be wondering how to move a pump organ. There are a few components to consider when moving the organ. For instance, it has several pipes: Flue, Exhaust and Reed. You will also have to remove the Cross-bar switch. Fortunately, these components are not very difficult to remove. But if you’re not comfortable working with them, you should contact a professional who can help you with this.
If you are wondering how to move the exhaust pipes on a pump organ, you are not alone. Most organs have this problem at one time or another. These pipes are spring-loaded and use two outer leather valves to draw air from a large air reservoir chamber. Heavy-duty springs and critical inner leather valves control air flow and are critical for the sound produced by the organ. To move exhausters, you must first remove the old bellows cloth and replace it with duplicate leather cut to fit the bellows. After that, you can install the new bellows cloth on the reservoir bellows and the divider board.
Firstly, you need to clean the organ case. You can use various beeswax formulations as polishes, but this will only leave the case with dirt and beeswax residue. If the organ is ornate, you will also need a toothbrush and cotton swabs. Next, clean the instrument’s interior. Clean any dirt and beeswax residue from the case using Murphy’s oil soap and a damp rag.
The most basic and oldest type of pipe used to move a pump organ is the flue pipe. This type of pipe has no moving parts, and it uses wind to create the sound. Wind enters the pipe at its foot and hits an upper lip. The wind is then forced back into the pipe by the lower air pressure. The pipe’s length and type of top closure will determine the pitch of the sound produced.
Flue pipes in a pump organ are made of several different materials. The material and scale used to make them affect the tone. Flue pipes are made of wood, or from various metal alloys. Some types of pipes may have a tuning collar or tuning sleeve to adjust their pitch. Some flue pipes may even have a tuning sleeve, so the tone can be adjusted.
Flue pipes in an organ usually produce the lowest frequency sound. They may be wide or narrow. The most common types of organ flue pipes are flutes. Flue pipes in a violin or a viola are called “flutes.” Organs that produce these notes are often the largest and most beautiful. Many organs use a combination of flute and pipe pipes to produce the highest-quality sound possible.
A pump organ has several ways to control the quality of sound it produces, and one of those ways is to move the reed pipes. While the pipes on the organ can be moved, there are other methods that must be used to create a sound that sounds better. Here’s a quick explanation. You may want to use the manual method if you have no knowledge of mechanical instruments.
In the past, many of these instruments have survived in private collections or in museums. Several of these instruments are located at Black Creek Pioneer Village in Toronto, Brome County Historical Society in Knowlton, Quebec, and the Bruce County Historical Museum in Southampton and Amherstburg, Ontario. Other collections include the Organery collection, by Jan van der Leest of Truro, the Trent River Museum, the Glenbow-Albert Institute in Calgary, and the Jan van der Leest organ in Truro, Nova Scotia.
The reed organ was a relatively inexpensive instrument compared to a piano. It required less maintenance, but lacked the resonator quality and individuality of pipe sounds. By the 1880s, reed organs became popular in homes and small institutions, but gradually declined in popularity. Larger companies started building two-manual reed organs for churches. This style of organ had less individuality and more consistency than pipe organs.
The Cross-bar switch on a pump organ controls the volume of the sound produced by the organ. It is located near the center of each stop tablet 20. Pushing the end closest to the organist to open the stop and depressing the end further away to close it will close the stop. The organist can also adjust the volume of the instrument by using the controls on the organ. These controls make the organ play a variety of sounds.
There are two types of switches in a pump organ: a horizontal and a vertical one. The horizontal bar energises the first connection, while the vertical bar energises the second. The cross-bar switch is typically referred to as a TXK or TXC, depending on the instrument. It is referred to as a type of relay switch. Depending on how it works, it can also be used for a telephone.
The cross-bar switch on a pump organ operates by regulating the flow of sound to the instrument. It comprises a series of plastic support blocks that are arranged in parallelism with the actuator 78. The support plates are made of Lucite and are provided with a series of openings that are substantially circular and arcuate along the upper edge. Each support block has a screw 76 that threads through each of the keys. The spring end deflects upward beneath each key so that it maintains the tension and maintains the screw in its adjusted position.
First, you will need a glue pot. A fully automatic one is best, but if you’re on a budget, a basic electric hotplate with a meat thermometer will work just as well. Once you have a glue pot, you can purchase dried glue from Organ Supply Industries. Mix the dried glue with two volumes of COLD water and one volume of flake glue. Heat the glue until it reaches 140 degrees F. If left overnight, the glue will not spoil. In a few days, the glue will begin to harden and grow.
Once you have glued the mute onto the new wooden strip, you can begin to move the organ. Make sure to mark the exhausters so that you know which mute is on which string. You should also remove the old silks if you can. They are often red cotton poplin and were glued on with hot glue. If you want to be sure the new silks will fit properly, you can use a shard of the old silk.
Before you attempt to move the action, you should thoroughly clean the case. If there is any black or dark material on the tongues, it is most likely soot. This is particularly common on older organs that were used regularly. The black stuff will be greasy and need to be removed. The reeds should also be cleaned if they contain corrosion products or other black stuff. Then, you can reinstall the action.
Moving a reed organ
There are two basic methods for moving a reed organ: hand and foot pumping. In hand pumping, you press the keys to make them play, while foot pumping causes the strings to wiggle and sound funny. Hand pumping also increases the sound quality of the instrument, and can be done with relative ease. A Lee Unit is an effective way to pump a reed organ without the need for foot pumps, as well as avoiding the need to alter the organ’s appearance. Lee Units are available for small parlor organs and melodeons, as well as larger church types. They feature sturdy motors, specially designed aluminum fan assemblies, and shock-mounted enclosures. Everything you need to install one is included in the kit.
Another method involves filing the bar clamped at one end to raise or lower its pitch. This produces a variety of vibrational modes, and each mode has a specific number of nodes. In this way, the frequency of the sound produced by the reed organ is determined. However, if the bar is too small, the instrument will sound hollow and unattractive. Moreover, moving a reed organ manually is difficult because the bellows must be clamped at two locations.
The reed organ’s fundamental frequency is the lowest frequency. Each individual note has a different amplitude. The middle C, for example, ranges from 8.0 to 10.0 to 2.5. The note E, which has three stops, stays constant at 3.0, but drops to 1.5 for Stop #4, Forte. The other two notes, G and C, range from 1.0 to 3.0, respectively. The volume of the organ increases in stops Forte, Aoline, Celeste, and Melodia.
