Abstract: A feed mechanism for use with a drain cleaner includes a frame configured to be coupled to the drain cleaner. The frame including a cable passage defining a cable axis. The feed mechanism includes a plurality of rollers including a translatable roller. Each roller defines a roller axis. The translatable roller is moveable between an engaged position and a disengaged position. The feed mechanism includes a mode selection member coupled to the frame and moveable between a first position in which each roller axis is parallel to the cable axis and the plurality of rollers are configured to spin the cable about the cable axis, and a second position in which each roller axis is non-parallel to the cable axis and the plurality of rollers are configured to move the cable in a first direction along the cable axis.

Abstract: A transportable machine including an elongated frame having a top end and a bottom end, a handle disposed on the top end of the frame, a base disposed on the bottom end of the frame, where the base and the frame together define a space configured to receive and support a load, and a wheel disposed on the bottom end of the frame. A track is coupled to the frame, where the track includes a roller and an endless belt configured to rotate about the roller. A motor is coupled to the roller, where the motor is operable to drive the endless belt, and a power supply provides power to the motor.

Abstract: A method and apparatus for delivering and retrieving workpieces to and from a machine table. This invention also relates to an apparatus for receiving at the machine table workpieces which are delivered to and retrieved by the delivery system. Carriers move along a conveyor without a loading arm rotating with respect to a supply table and also without the supply table rotating with respect to the loading arm. The receiver has pivot arms that act in a scissor-like manner to open and close an opening that lockingly engages a connector connected to a pallet.

Abstract: A rotary pallet device for delivering a pallet to an automated machine, such as a CNC vertical machining center. A pallet is mounted to a retractable slide. The retractable slide is movably mounted with respect to a rotatable platform. An operator or worker accesses one or more stations, each with a rotatable door that at least partially houses a receiver for a pallet and/or a workpiece.

Abstract: A caster for providing rolling support including a spring-loaded mount. The caster may be substantially concealed in the bottom edge of a hinged, swinging door, and generally located proximate to the free vertical edge of the door. An elongated spring plate is provided as a mount for a roller, causing the roller to accommodate variations in the floor surface, maintain contact with the floor, and support the door. The spring plate has a first portion adapted to be mounted to the bottom edge of a door, and a second portion depending from the first portion. An axle is mounted to the second portion, inside a hub that is mounted to the roller. The axle may be substantially parallel to the first portion of the spring plate. Single roller and double roller caster assemblies are provided.

Abstract: A track and arm type door controller assembly. A channel member and a gripping member each having a toothed surface are provided, with the gripping member slidably disposed in the channel member. When the pin is retracted, the gripping member teeth are spaced from the channel member teeth, and the gripping member may freely slide along the track. When the pin is advanced, the teeth engage and the gripping member is in a fixed, non-sliding position. An elongated spring and a spring clip or a latch may be provided that releasably engage to hold the door open. A set screw may adjust the tightness of the engagement of the elongated spring and spring clip of latch. A friction assembly may be provided to slow the motion of the door.

Abstract: A dust trap for flowing gases comprises an inlet conduit which terminates in a transverse wall for impact-type dust separation (i.e. inertial separation). A side entry port is positioned adjacent the transverse wall. The side entry port communicates with the circulation chamber defining an angled opposed wall in the opposite side of the chamber of the side entry port. The angled, opposed wall is substantially perpendicular to gas flow through the side entry port, to cause flowing gas from the side entry port to split vertically into swirling upward and downward flow patterns for further dust separation. The lower part of the circulation chamber is normally closed off from the exterior. The upper part of the circulation chamber communicates with an outlet conduit.
