An adjustable baton to be used for twirling is provided having an elongated shaft formed from a hard material such as stainless steel. A resilient ball is mounted at one end of the shaft and a smaller resilient tip is mounted at the other end thereof. The shaft comprises three axially aligned tubular pieces, namely a main shaft with an extension shaft mounted at each end thereof. Mating internally frusto-conical surfaces are formed at the ends of the main shaft and the extension shaft at each end of the main shaft has a mating externally frusto-conical surface to be received by the mating surface of respective end of the main shaft. A threaded rod internally received by each extension shaft and one end of the main shaft is provided for each extension shaft to connect the extension shafts to the main shaft. Adjustment is accomplished by extracting a desired length of threaded rod from inside the main shaft. Adjustable threaded bushing to eliminate play between the rod and the respective extension shaft and these parts are fastened securely by a locking device such as a lockwasher and nut. The tip end has a weight therein to counterbalance the larger resilient ball at the other end of the shaft. The length of the baton is adjusted by substituting extension shafts of different lengths.
An adjustable balanced twirling baton comprising an elongated hollow cylindrical main shaft, a short hollow internally threaded tubular extension shaft at one end of said main shaft, a first threaded adjusting rod internally received by and connecting together said shafts, a longer internally threaded tubular extension shaft at the other end of said main shaft, a second threaded adjusting rod internally received by and connecting together said main shaft and said longer extension shaft, said main shaft having a frusto-conical mating surface on each end, a frusto-conical mating surface on one end of each extension shaft to mate with the respective mating surface at the ends of said main shaft, a fixed bushing on one end of each of said adjusting rods slidably received within said main shaft, an adjustable bushing threadedly mounted on a central portion of each of said adjusting rods and slidably received within the respective extension shafts, an internally threaded locking device threadedly mounted on the free end of each adjusting rod to secure said extension shafts in abutting contact with the respective ends of said main shaft, a resilient ball mounted on the free end of said longer extension shaft and a smaller resilient tip mounted on the free end of said short extension shaft.
