Abstract: A training bat for ball games is shown as including a handle, a ballast, and a ballast adjustment structure. The ballast adjustment structure further includes an adjustment stem attached to the handle, and ballast attachment structure connecting the ballast to the adjustment stem. The handle, stem and ballast are attached coaxially to one another, and the adjustment stem includes external thread convolutions formed along its axial length adapted to provide selective adjustability of the ballast relative the handle along the longitudinal axis of the bat. The selective adjustability of the ballast is provided by rotation of the ballast relative the handle while the handle, adjustment stem and ballast are integrally attached.

Abstract: A self-loading machine for dispersing material contained in large bales. The machine has a generally trough shaped body with a movable side which lowers to engage a bale and raises to load the bale into the machine. A cylindrical rotor is made up of a series of plates having hammers which are pivotally attached at alternate locations between the plates. The machine is also provided with a conveyor which, in conjunction with the action of the rotor, serves to tumble a round bale as material is removed and peel off material from the bottom of a rectangular bale. As material is removed from the bale, it is mixed with air generated by the rotor and discharged in a uniform stream at high velocity from the machine.
