Abstract
A cooling system for cooling the cutting edge of an impact type ripper tip includes a source of liquid coolant under pressure and conduit means for supplying the coolant to a spray head mounted below and behind the ripper tip in a position to distribute liquid coolant to the lower surface of the tip behind the cutting edge. The spray head is detachably mounted directly behind the ripper tip and projects downward beyond the lower surface of the tip.

In an impact rock ripping machine having an elongated and downwardly extending ripping shank with a forwardly extending rip mounted on said machine for receiving intermittent impact blows for driving the shank and tip in a forward direction at intermittent high speed intervals the improvement comprising:
- cooling means for distributing a flow of coolant to said tip for controlling the temperature thereof comprising a spray head mounted beneath said shank and disposed intermediate lateral sides thereof and behind said tip and having a plurality of spray openings positioned thereon to direct a spray pattern of coolant to an underside of said tip and fully thereacross;
- an adapter having a first socket receiving a forwardly extending projection of said shank in mounting relationship therein and a second socket having said tip detachably mounted therein;
- and
- spray head mounting means on said adapter mounting said spray head thereon, adjacent to said tip.
In an impact rock ripping machine,
- a ripping shank,
- an adapter mounted on a forward end of said shank,
- a tip detachably mounted on a forward end of said adapted, and
- cooling means for distributing a flow of coolant to said tip for controlling the temperature thereof comprising
- a pressurized source of coolant,
- a spray head mounted beneath said shank and havng a plurality of openings positioned thereon for directing coolabt forwardly and across an underside of said tip,
- means for communicating coolant from said source to said openings, and
- spray head mounting means comprising a slot having sloping sidewalls formed in said adapter and sloping sidewalls formed on said spray head and engaging the sloping sidewalls formed in said adapter for being retained in position thereby.
