Abstract: A ball is slidably mounted on a horizontally extending track which is supported by a tripod. The tripod has an upwardly extending post and a support arm which is adjustably attached to the post and extends transversely therefrom. The support arm is adjustably attached to the track to support the same. An upper rail is spaced above the track and extends parallel thereto to form an open ended bat guideway. The ball is mounted on a carriage which slides within the guideway and is spring biased to normally hold the ball in the open end of the guideway. The position of the ball and orientation of the guideway with respect to a batter can be easily adjusted to be disposed at any desired position within an individual batter's strike zone by the adjustments on the tripod and support arm. When the bat is properly swung, it hits the ball squarely and knocks the ball down the guideway to the end of the track, where the ball carriage strikes a resilient bumper.

Abstract: A label applying turret having label support pads, a label marker and a pressing platen for pressing the label against the marker. The marker is mounted on the turret to rotate therewith and faces outwardly against the inwardly facing side of the label. In one embodiment a label gripping platen is aligned with the marker so that its action in gripping the label to the turret concurrently imposes die marking pressure on the label. In another embodiment a roller platen is mounted externally of the turret and presses the labels against the die marker.This application is a division of copending application Ser. No. 381,184 filed July 20, 1973, now U.S. Pat. No. 3,893,388, which was a continuation of copending application Ser. No. 223,204 filed Feb. 3, 1972, now abandoned.

Abstract: A trash compactor with a housing having a head space at its top, a trash container at its bottom and a trash loading space between the head space and the trash container, a trash loading port in the side of the housing aligned with the trash loading space, a pressure platen and a lazy tong or scissors extension linkage mounted at the top of the housing and operable to move the platen between one or more advanced positions in which the extension linkage spans across the trash loading space and the platen is imposing compacting pressure on trash within the container, and a retracted position in which the extension linkage and platen are withdrawn into said head space, thus leaving the intervening trash loading space open for loading trash into the container through said loading port and without having to withdraw the container from the housing for loading purposes.
