Abstract: REVERSING HAMMER DRILL          ABSTRACT OF THE INVENTION    A hammer drill having a bypass switch which is activated by the selector ring to prevent the drill from operating in the hammer mode by shunting the reversing switch.  This is a precaution to prevent damage to the clutch teeth which are designed for ratchet action when the tool is operated in the for-ward direction, but will lock down in reverse to stall tool or damage the mechanism.  In the drill mode, the bypass switch connects the reversing switch in circuit with the on-off switch.

Abstract: 1.     DOUBLE ACTING FLUID OPERATED PISTON          CYLINDER ASSEMBLY                ABSTRACT OF THE DISCLOSURE      An elongated cylinder housing has a piston therein molded from a resinous plastic material.  The piston has an angularly extending slot receiving a metal clutch roller operated by a clutch control bar slidable relative to the piston.  The clutch control bar is secured to a secondary piston member, and springs are disposed between the piston and the secondary piston member for normally causing the control bar to pull the clutch roller into an engaged posi-tion.  The clutch roller is disposed in such engaged posi-tion to prevent travel of the piston in one direction except when actuating fluid in the cylinder operates on the second-ary piston member against the force of the springs to cause the clutch roller to move the clutch control bar into a re-leased position.  The bottom of the slot that receives the clutch roller is covered by metal plates to permit free roll-ing engagement of the clutch roller thereon and at the same time to prevent indentation of the clutch roller into the plastic.  The roller support plates are retained in the slot by interfitting projections and notches.

Abstract: Abstract The steering assembly disclosed has means for sensing changes in both lateral offset and angle between a towed and a towing vehicle, means for generating angle and offset signals responsive to such changes, means for combining the angle and offset signals to produce a joint steering input, and means for turning a steerable wheel of the towed vehicle in response to the joint steering input.  The assembly has two operating modes, one in which offset signals and angle signals are subtracted to produce a joint steering input for forward travel of the vehicles and another in which offset signals and angle signals are added to produce a joint steering input for backing of the vehicles.  The assembly also includes steerable wheel means, means for detachably coupling the vehicles together, and means for remotely shifting between the two operating modes.

Abstract: ABSTRACT      An industrial loader vehicle, handling both wet and dry materials, has a single engine driving the vehicle to a pick-up site, powering all of the components to load the vehicle at the site t driving the vehicle to an unloading site and dumping the materials as desired at the unloading site.  A powerful blower develops a high velocity air stream through a pick-up inlet conduit and a collector chamber tiltable on the vehicle for easy dumping of the collected material.  A swingable and tiltable boom mounted on top of the collector presents the conduit for easy access to material located around and above the vehicle.          The high velocity air stream sweeps the material through the conduit into the top of the collector chamber where it drops to the bottom of the chamber.  The blower and surrounding environment are protected from materials entrained in the air stream by bag filters and cyclone separators mounted on the front end of the collector to tilt therewith.  The air outlet of the cyclone separator communicates with the blower through a self-sealing coupling and if desired a micro-filter may be interposed between this coupling and the blower.  Doors accessible from the outside of the collector selectively direct the exiting air to the bag filters and cyclone separators for dry pick-up or to the cyclone separator for wet pick-up.          The air received by the blower and discharged to the environment is thus freed from particulate matter.  The vehicle is especially useful as a vacuum cleaner for debris to be transported to a dump.
