Publication number: 20090236898Abstract: A groove is formed in a body of ice using a milling cutter to form lines of weakness for breaking up the body of ice. The shaft of the milling cutter is arranged to be supported in an upright orientation such that the shaft extends through a surface of the body of ice into the body of ice. Rotating the shaft as the milling cutter is displaced along the surface forms a groove which can follow a variable path to follow natural obstacles when cutting across a body of ice on a natural body of water for example. The ice milling cutter is compact and therefore safer to use on sheets of ice as compared to heavy equipment conventionally used for breaking up ice.Type: ApplicationFiled: September 19, 2008Publication date: September 24, 2009Inventor: John Szukiewicz

Patent number: 4718729Abstract: An apparatus and method for clearing material from one location to a pile at another wherein a trolley member with a winch is suspended below and supported by a track which in turn is supported on a moving platform such as a drilling platform or a barge. The winch member by means of the usual lifting cable is connected to a material confining member which also is connected to a drag line cable. Movement of the trolley member over the tracks by means of the drag line will cause the material confining member to collect the material. A subsequent lifting of the lift cable as well as operation of the drag line will allow the material to be elevated and placed on a rubble pile at the side of a channel. In a preferred manner, the apparatus and method of this invention is especially suited for use in clearing ice from a channel which is previously cut by ice cutters also associated with the moving platform which carries the clearing apparatus.Type: GrantFiled: September 15, 1986Date of Patent: January 12, 1988Assignee: Becor Western Inc.Inventors: Carl D.

Patent number: RE29356Abstract: An ice chipper comprising a pair of cylindrical drums each mounted for counter-rotation about parallel, generally vertical axes. Each drum includes an outwardly rounded, disk shaped bottom surface and an auger flight spiraled helically about the outer cylindrical surface thereof.

The chipper is mounted to the front of a tractor and each drum includes a hydraulic motor which is operated by a hydraulic pump also carried by the tractor. Rotation of the drums causes the auger teeth to chip the ice and tends to pull the drums forwardly while the auger flights carry the ice particles up and out away from the cleared area. Tilting the system forwardly and rearwardly upon the rounded drum bottom surfaces varies the depth of cutting in the vertical direction.Type: GrantFiled: September 20, 1976Date of Patent: August 16, 1977Assignee: Sun Oil Company (Delaware)Inventor: John D.
