Abstract: A slip hitch connection to a drive vehicle for a snow plow comprises an elongated flat planar member that can be hooked on to a connecting lug of the drive vehicle, the flat planar member being mounted on the snow plow frame for reciprocal movement in each of a pair of spaced apart coupling assemblies secured to the snow plow frame for connecting the snow plow to the drive vehicle. Each of the elongated flat planar members have an upper and lower elongated guide slot in which guide bolts that move up and down as the snow plow itself is moved up and down are received to enable the guide bolts and snow plow to which they are connected make limited reciprocal movement up and down while hooked up to the drive vehicle and being pushed forward during a snow plowing operation.

Abstract: A sectional snowplow having a plurality of separate sections, each mounted separately and independently to the snowplow frame for limited movement upwardly and downwardly relative to the sections of the snowplow on either side, whereby one section can rise to scrape over a rise in the surface below that section without causing the sections on either side to also rise above the surface below such other sections. Each section is mounted separately and independently to the snowplow frame by flexible members of a resilient but nevertheless sturdy material such as polyurethane. A preferred material is known in the trade as polyurethane 90 A Shore hardness.

Abstract: A window crank assembly for casement windows comprising a metal window crank having wing type hand grasp members extending laterally in both opposite directions from a central hub and a plurality of insert members, which are preferably metal but may also be plastic, receivable in the cavity of the hub, each of the insert members having an insert cavity of a different cross-sectional dimension and internal configuration to match the different cross-sectional dimension and external configuration of the different crankshafts of casement window operators made by the various casement window manufacturers. A set screw extends through aligned apertures of both the window crank hub and one of the inserts when received therein to bear against a portion of the casement window crankshaft received in the insert cavity which is inwardly thereof from an enlarged outwardly projecting spline portion of the crankshaft.
