Castle TSM-21 Serial 61064 and lower (Mead) Operator Manual - Manual (Page 14)

Description of Parts
1. Clamp Cylinder: The large cylinder on the top of the
machine is a clamp to hold the stock safely in place during
operation. This is a single acting, spring return pneumatic
cylinder with a padded foot on the end of the cylinder rod.
The clamping force exerted is directly proportional to the
amount of air pressure received by the machine. The clamp
guard secures the clamp cylinder.
See above 2. Clamp Guard: The yellow metal clamp guard on top of
the machine serves to secure the clamp cylinder and to
safeguard the operator from the clamping and pocket cutting
action.
3. Router Stop Plate: Located at rear of machine, this black
metal plate extends up through the top of the case along the
right side of clamp guard. The position of this plate
determines the size of the “web.”
4. Foot Pedal and Guard: The foot pedal is mounted inside a
yellow metal guard and is connected to the machine by an
electrical cord. When pressed, the foot pedal will activate
the machine cycle only if the safety buttons are depressed
by the stock.
5. Safety Buttons: Two small silver button head screws that
project from the front of the machine under the clamp guard.
The machine does not cycle unless one of these buttons is
depressed simultaneously with the foot switch.
6. Safety Switch: This magnetic proximity switch is mounted
on the inside top of the TSM-21. It is activated when the
safety buttons are depressed by a piece of stock.
7. Motor Carriage: The motor carriage is the yellow A-frame
structure inside the machine. Both the router motor and the
drill motor are mounted to this carriage. The carriage is
moved back and forth through the machine cycle by the
drive cylinder, which links the carriage to the machine case
in front.
