<p>An ice resurfacing machine having a sled or housing that mounts a brush or auger and an ice shaving assembly which is mounted in the housing for pivotal movement about a first transverse axis to adjust the depth of cut and a second transverse axis to adjust the angle of cut. The shaving assembly includes a blade, a blade holder and a clamp bracket that are secure together to hold the blade, and permit easy replacement of the blade. In one embodiment the blade holder has protrusions or inserts extendable through apertures in the blade to facilitate holding the blade in position during the time the blade holder, clamp bracket and blade are attached to and removed from the angle support or mounting bracket, or permit replacement of the blade while the clamp bracket and blade holder are still attached to the angle support. In another embodiment the blade holder and clamp bracket have protrusions extendable into slots in the blade while in a further embodiment a cam member is provided for moving the clamp bracket relative to the blade holder for releasably clamping a blade. Preferrably the transverse outer, bottom surfaces portions of the blade support, blade holder or clamp bracket are machined away so that the blade in vertical, transverse cross section and its cutting edge will extend upwardly and outwardly relative the transverse intermediate portion thereof.</p> |
