A plow assembly useful for moving material from surfaces such as roadways in various selectable discharge directions includes a moldboard assembly and pivotable frame. The moldboard assembly is capable of being oriented in a right side discharge or a left side discharge in response to pivoting movement of the pivotable frame. A tripping mechanism is included to prevent damage of the plow assembly from obstacles located on the plowing surface. A cutting edge of the plow assembly is secured to the moldboard assembly by a wedge mechanism thus allowing quick cutting edge replacement.

A power broom assembly includes a vehicle, a rotatable broom mounted to the front of the vehicle, and an airblast assembly mounted to the front of the vehicle above the broom to suck up an overspray of material which has been swept up by the broom. An airblast assembly for use in the power broom assembly includes a casing, a cross flow blower in the casing, and at least two outlets in the casing which are selectively openable and closeable by flexible wall portions which are movable radially inwardly and outwardly to substantially change the inner contour of the casing. A drive system of the power broom assembly includes a first transmission unit which has first and second output shafts, and a second transmission unit which includes an input shaft. At least the first and second output shafts of the first transmission unit and the input shaft of the second transmission unit are aligned along a single axis.

A snowplow mounting apparatus for use on trucks and the like is provided in which a pair of clam-shell plates are mounted on the front of the truck in place of the usual bumper. The plates are pivotally joined together at the top. The removed bumper is mounted on the outer plate of the clam-shell and the actuating hydraulic cylinder is mounted within the clam-shell where it is fully protected. The plow blade is mounted on the outer clam-shell with a quick disconnect feature and a pair of cam surfaces is mounted on the inside of the clam-shell plates. The hydraulic cylinder through cam followers cooperatively engaging said cam surfaces force the plates apart about the pivot point of the clam-shell which raises the plow from engagement with the surface being plowed. The entire mounting apparatus being positioned in place of the bumper, with the bumper on the front of it offers a clean, unobstructed front bumper for the truck that will function as the original bumper was intended to function without interfering protrusions extending forward of the front bumper when the plow blade apparatus is removed.

A chipper knife blade assembly for a rotary disk chipper has first and second flat knife blades of substantially identical construction, with one of the blades serving as a chipper blade and the other serving as a counterknife supporting the chipper blade. The counterknife is seated on a sloping support surface in a recess in the disk and has its proximal edge reposed against a support or a thrust bar. A bolt-down clamping member has a shouldered surface with a flat portion clamped down against a top surface of the chipper knife blade, and with a shoulder supporting the proximal edge of the chipper blade. In a preferred embodiment, the chipper blade projects about one-half inch to three-quarters inch beyond the cutting edge of the counterknife blade. With this arrangement, a warn cutting blade can serve a second useful life as a counterknife, absorbing the wear that results from the chips moving at high speed into the chip slot.

A horizontal disk wood flaking machine has two or more continuous feed conveyors each of which has a vertical chute or feed box that brings wooden logs to an upper surface of the cutting disk. The drive motor for the disk is situated below the disk at the under side of the machine, so that the power train is from the bottom upwards.

A knife assembly for a wood chipper has a cassette, a top blade holder, and a trapezoidal cross-section double-edge blade. The cassette is of profiled cross-section, with a full-width proximal section, a stepped-down blade holder support surface on an intermediate section, and a blade support surface on a distal or tip section. A proximally and downward sloping surface extends from a distal edge of the blade holder support surface to the blade support surface. The blade has substantially flat upper and lower surfaces so as to avoid structure which is susceptible to snapping or splitting under the stresses normally encountered in a chipping operation. One edge of the trapezoidal blade is exposed and extends forward of the cassette and the blade holder. The tapered ground surface that defines the concealed edge of the blade faces against the sloping surface of the cassette. Molten babbitt is poured through openings in the blade holder to form babbitt shims filling the space between the concealed blade sloping surface and the sloping surface of the cassette. Thus, the blade is supported both from beneath and at the concealed ground or tapered surface. Further, the babbitting provision permits precise positioning and adjustment of knife projection.

A coupler for rapidly joining a snowplow unit to a prime mover. A horizontally extended tongue is affixed to the push frame of the plow unit which is insertable into a receiving slot contained in the coupler. The tongue is provided with a pair of contoured camming surfaces that are arranged to translate a prescribed motion to a pair of jaw elements contained in a locking mechanism carried by the coupler. The jaw elements are biased to move in contact with the camming surfaces to first move to a fully opened position to allow the tongue to pass into the coupler and then into closed or locked position wherein the push frame of the plow unit is securely drawn into seated contact against the front wall of the coupler. A locking bolt is operatively connected to the locking unit and is adapted to automatically swing into a receiving hole formed in the tongue when the jaw elements are moved toward the locked position and to be lifted from the hole when the jaw elements are moved to a predetermined, partially-opened position.

Apparatus for automatically locking the blade mechanism of a vehicular driven snowplow at a desired angular position in regard to the forward line of movement of the vehicle. The locking device is adapted to automatically release the blade mechanism when the blade is raised from a normal snow clearing or working position and to move back automatically into locking engagement when the blade mechanism is lowered into the same or a new angularly disposed working position.

A truck has a pusher frame secured to its front end and has a space between its cab and its body at the rear. A front post is secured to the pusher frame and a rear post is secured to the vehicle frame between the cab and body. Each post includes a vertically disposed rectangular tubular way having a slot along one side and a double acting hydraulic cylinder having its piston rod secured to the bottom end of the way and the lower end of its cylinder secured to the rectangular portion of a pair of spaced plates adapted to slide within the posts. The cylinder has a piston secured to the upper end of a double tubed piston rod, one tube being telescoped within the other and having an annular space therebetween, the central tube extending beyond the other at each end. Both connecting rod tubes have means for admitting fluid under pressure at their lower ends, the space between the tubes being sealed at this end, the inner tube extending through the piston at its top for expanding the device and the outer tube having openings below the piston for connecting the space between the tubes to the cylinder for lowering the cylinder. The pair of spaced plates of the slide have a narrow tongue portion projecting through the post slots and connected to a vertically extending slide portion slidable on the exterior of the post. A patrol wing plow blade has its front end pivotally connected to the front post slide and its trailing end pivotally and adjustably connected by a plurality of arms to the rear post slide.

An operating and shock cylinder assembly for vehicle mounted underbody scraper and grader blades, plows and the like. The assembly of cylinders operates with hydraulic fluid and air, both under pressure, to move the blade or plow between retracted and road engaging positions. It also permits the blade to trip or yield when it engages a fixed obstacle in the road after which the blade quickly returns to its road engaging position. The assembly includes a pair of coacting cylinders which are first charged with air under pressure after which one of the cylinders is charged with hydraulic fluid under pressure. The hydraulic charge forces all of the air into the other cylinder and further compresses it, and this air operates as a powerful spring force or load on a piston in the cylinder that is connected to the pivotally mounted blade. Under this condition, the blade is firmly but yieldably biased into road engaging position. When not in use, the blade can be retracted by exhausting the compressed air from the air loaded cylinder and moving its piston by hydraulic fluid to lift the blade out of contact with the road.
