Abstract: A blade holder for holding a disposable ice shaving blade on an ice resurfacing machine has an attachment member which is attached to an appropriate support member on the ice resurfacing machine. The attachment member has an elongated "V" shaped groove which extends across the transverse width of the attachment member. A triangular shaped retaining member mates against a surface in the .-+.V" shaped groove on the attachment member. A surface on the attachment member and a wall on the retaining member which are spaced apart from each other in a parallel relationship when the retaining member mates with the attachment member, form a cavity for excepting and retaining a disposable ice shaving blade. The retaining member is connected to the attachment member utilizing a plurality of attaching elements such as appropriate bolts or the like. These attaching elements are independent from the structure which is utilized to attach the attachment member to the appropriate support member on the ice resurfacing machine.

Abstract: A board brush apparatus for use on a self-propelled ice-resurfacing machine of the type having a frame supporting apparatus for shaving the surface of the ice and removing the shavings, and including a source of pressurized hydraulic fluid. The apparatus includes a mounting bracket that is adapted to be attached to the frame on one side of the machine, and swingably connected to this frame is an arm having a motor-driven rotary brush at the outer end thereof. The arm is swingable between a laterally extending operational position and a retracted position, and is moved from one position to the other by a hydraulic cylinder which is attached at one end to the bracket. The piston rod projecting from the other end of the cylinder is connected to the arm through an intermediate shock absorber.
