Tire tube clamping apparatus

A tire tube clamping apparatus comprising:

• a frame member;
• a tire tube mandrel attached to said frame member;
• a upwardly opening, substantially U-shaped yoke disposed adjacent said mandrel and movable with respect thereto, said yoke having a pair of integral arms;
• and
• a clamping bar extending substantially perpendicularly from each of said arms and positioned adjacent said mandrel for clampingly engaging a tire tube thereon.

A tire tube clamping apparatus comprising:

• a base;
• a substantially vertical frame extending upwardly from said base and rigidly connected thereto;
• a curvilinear mandrel rigidly attached to an upper end of said frame;
• at least one rod guide rigidly attached to a side of said frame;
• an actuating rod extending substantially parallel to said frame member and slidably received in said rod guide, said rod having an upper end and a lower end;
• a foot pedal pivotally connected to said lower end of said rod and further pivotally connected to said frame such that downward actuation of said foot pedal will force said rod upwardly;
• and
• a yoke assembly attached to said upper end of said rod and movable therewith, said yoke assembly comprising:
• a substantially U-shaped yoke having a pair of outwardly flexible arms extending upwardly from said actuating rod and substantially co-planar therewith;
• and
• a pair of clamping bars extending perpendicularly from upper ends of said arms and disposed on an uppper side of said mandrel, said bars having a clamping position adjacent said mandrel for clamping a tire tube thereon wherein said tire tube is pulled tightly across said mandrel between said bars by flexible action of said arms and an unclamped position spaced upwardly from said mandrel.
