Abstract: A snowplow blade assembly provides a snowplow blade that attaches to a vehicle for clearing residue from a pathway. The snowplow blade is configured to minimize structural damage caused by a pathway edge barrier, or a stationary object disposed on, or along, the pathway. A break-away section of the snowplow blade hingedly pivots, and potentially detaches with respect to a remainder of the snowplow blade when a predetermined shear stress from the pathway edge barrier or stationary object is applied. The break-away section includes a wheel roller that facilitates rolling advancement of the snowplow blade along or on the pathway edge barrier. The break-away section also forms an outer edge recess on a first side-blade end of snowplow blade. The outer edge recess is sized to enable passage of stationary objects, which prevents damage to the snowplow blade or stationary objects.

Abstract: An extension for a grader blade which is used to dig a concave ditch includes a body for mounting on or integral with one end of the grader blade, the body having a convex outer side edge adapted to scoop out a curved-bottom ditch when the grader blade is angled from the horizontal with the extension at the lowermost end of the blade, and moved through the surface.

Abstract: A weep hole blade is operably mounted on the heel of the grader blade of a motor grader which is movable between raised and lowered positions with respect to the grader blade to create weep holes or channels in a ridge of roadway material being deposited at the side of a road by the motor grader.

Abstract: A scarifying blade for use on earthmoving equipment (e.g. a road grader). The lower working edge of the blade has attached to it several spaced rotatable bits, and attached to at least one of the ends of the blade is an end rotatable bit at an angle of about 30 to 60 degrees relative to the spaced bits on the lower edge of the blade. The end bits prevent loosened material from spilling around the end of the blade and they also provide other additional advantages.

Abstract: A snow plow composed of a central blade and of two wing blades which are laterally hinged to the end of the main blade for wing blade angular adjustment forwardly and rearwardly of the main blade from a position and alignment with the same. Furthermore, the level of each wing blade with respect to the main blade can be adjusted. Also, tilt motion of the laterally outward end portions of the wing blades either upwardly or downwardly is also possible. Each blade consists of a flat panel and its bottom edge carries a striker lip which can pivot rearwardly during forward movement of the plow upon the blade striking an obstacle. The snow plow is supported by a structure in front of a vehicle having forward lifting and tilting arms, this structure allowing a snow plow to laterally tilt within a limited angle in accordance with the transverse inclination of the surface being plowed. Upon slight rising of the snow plow, its forward pitch angle automatically increases to a pre-determined limit.

Abstract: An attachment system for mounting road-maintenance equipment on a vehicle such as a motor grader includes a frame for mounting on the nose plate of the vehicle to support the conditioning equipment forwardly and partly outboard of the vehicle. The system includes pivotal attachment mounts for the front and rear ends of a draft frame of the conditioning equipment together with a strut for supporting the draft frame at a desired orientation during operation, and for raising the draft frame and surface conditioning equipment to a retracted position when not in use. A mast on the attachment system frame directs a cable to the rear end of the draft frame to effect raising movement of the latter to the transport position.

Abstract: A plow assembly is disclosed for vehicles such as pickup trucks and tractors for moving snow or other materials. The plow assembly has at least one extendable, forwardly pivotable plow wing which is extendable on one end of a main plow by sliding movement along the front of the plow between a retracted and an extended position in which the plow wing is generally aligned with the plow front surface. The plow wing is also pivotally mounted on a hinge for movement between the extended position and a forwardly angled position in which the plow wing front surface extends at an angle to the plow front surface. A power source connected to the plow wing is operable to move the wing between the retracted, extended and forwardly angled positions. Preferably, a latch assembly prevents pivotal movement of the plow wing to the forwardly angled position until the plow wing is in the extended position.

Abstract: An angled blade unit is attached to a loader bucket and, as the bucket is moved along a roadway, the blade unit plows excess roadstone away from a newly poured concrete gutter in order to prepare a roadbed for paving. A gage rides along the flag of the gutter and limits the depth to which the blade unit plows into the roadstone.

Abstract: An improved angling snow blade, of the type which pushes snow to the left or right as the supporting vehicle alternates directions across an area to be cleared, has a right (28) and left (29) side panel attached to hinge about the upper edge of the blade, whereby wider swaths can be taken as a result of either side panel blocking the snow from previously cleared areas. A removable bottom panel (31) hingedly attached at its leading edge to the lower leading edge of the side panels enables the improved blade to carry snow from one location and dump it in another and to pull snow away from vertical obstacles, particularly those surrounding corners.

Abstract: An edging apparatus for an ice resurfacing machine includes a guide operatively attaching to one of the side edges of the machine which is capable of being extended from the side of the machine such that it can contact an upright surface as, for example, a rink wall or a dasher board extending around the perimeter of an ice rink. Associated with the guide is an ice shaving blade which is capable of extending in a vertical direction upwards and downwards between a shaving position wherein it can contact the ice surface and shave the surface and a non-shaving position wherein it is lifted upwards from the ice surface. The guide is interposed between the end of the edge of the blade and the dasher board or the rink wall such that it is impossible to catch the end of the blade in the wall or dasher board yet it is possible to correctly position the end of this blade very close to the wall or dasher board allowing shaving of the ice surface to a point almost immediately adjacent to the wall or dasher board.
