The standard and top note magnets have a strong section die cast base and cap. The valve is held in position in the cap by a stainless steel strip , it is easily adjusted by the knurled top and locking ring. The cap can be removed if necessary without disturbing the valve setting.

The Compound magnet combines the function of a chest magnet and a primary pneumatic stage in one
compact assembly. Only the addition of an exhaust pneumatic power motor is needed to make a
compact, quiet and fast electro-pneumatic action.
A typical sound board action would have the power motor glued to the upper surface of the bottom board
and the compound magnet screwed to the underside with a boring connecting the two. Alternatively, a
compound magnet can be used as the primary stage of an exhaust pneumatic chest action.
Description of Operation
Chamber B is permanently connected to pressurised air through ports (not shown in the section drawing) that communicate with the boring for the magnet coil. The underside of the diaphragm is thus always pres-surised, whether the magnet is energised or not.
Pressurised air flows through port A into chamber C. Both sides of the diaphragm (B & C) are at equal pressure so the diaphragm produces no net force. The air pressure in chamber B pushes the disc valve D downwards and pressurised air reaches port E and hence the inside of the pneumatic power motor.
The armature lifts and chamber C is exhausted to atmosphere via port A. the pressure in chamber B is higher than that in chamber C. The diaphragm moves upwards because the area of the diaphragm is greater than the area of valve D. The pneumatic power motor exhausts to atmosphere via valve D.

Vertical Pallet Magnet
This is a solenoid-operated direct pallet magnet with 70 ohm coil and diode suppression. The unit has a unique method of adjustable air damping to give correct pipe speech and to control the speed of open-ing and closing of the pallet. To ensure correct seat-ing, the pallet has a flexible mounting.
The solenoid armature is finished in polished hard chromium plate, sliding in a fine bore brass tube.
The unit which should only be mounted vertically has a simple one screw fixing through a key hole slot. When tightened the slight concave foot is de-signed to prevent any unwanted movement.
Note: These units should only be used in a dry and clean location.

Kimber Allen’s three types of Lever Magnets have the common features of a strong steel frame and ar-mature, with a non magnetic retentive pole. The stainless steel pivot has a plastic leaf inserted be-tween the frame and the armature to ensure silent and frictionless operation. Diode suppression is fit-ted as standard to the colour coded coils. Black
100 ohms, Green 70 ohms, Red 50 ohms.
- Solid extension arm available
Free Lever Magnet
The Free lever is a simple magnet with an adjust-able extension arm, having three .090″ dia holes intended for tapped wires etc.

Direct Pallet Magnets
These two types of magnets follow the general design fea-tures of the lever magnets. They are intended for direct pal-let operation, and are easily installed and have full adjust-ment of the return spring and regulation of the armature. The coils follow the same colour coding as the lever mag-nets and have diode suppression.
Direct Pallet Magnet
This Direct magnet has an adjustable pallet and pallet shoe. Pallets illustrated at the bottom of this page can be supplied as separate items or can be factory fitted. If this is required please state pallet size required.
