US4070064A — Cooling system for rock ripper tip

Claim 1

Independent Claim 150 words

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.

Claim 2

Dependent Claim 150 words

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.

Claim 3

Dependent Claim 29 words

The machine of claim 1 wherein said cooling means further comprises: a pressurized source of fluidized coolant; and means for communicating coolant from said source to said spray head.

Claim 4

Dependent Claim 53 words

The machine of claim 1 wherein said spray head mounting means comprises: a slot having sloping sidewalls formed in the lower forward edge of said adapter receiving said spray head therebetween; said spray head having sloping side walls engaging corresponding the sloping side walls of said slot for being retained in position thereby.

Claim 5

Dependent Claim 19 words

The machine of claim 3 wherein: said spray head projects downward beyond the lower surface of said ripper tip.

Claim 6

Dependent Claim 35 words

The machine of claim 3 wherein said slot is semi-frusto conical in shape with an open front opening toward said tip; and, said spray head is semi-frusto conical in configuration with a semi-cylindrical front face.

Claim 7

Dependent Claim 35 words

The machine of claim 5 wherein said openings are formed in said semi-cylindrical front face; and said face is exposed at the open front of said slot and extends beyond the surface of said tip.

Claim 8

Dependent Claim 28 words

The machine of claim 1 wherein: said machine includes a housing supporting said ripping shank for movement relative thereto; and, said spray head is mounted on said housing.

Claim 9

Dependent Claim 43 words

The machine of claim 1 wherein said spray head further comprises: a first cylindrial body having an inlet passage communicating with a central chamber; and, a cap having said plurality of openings formed therein and means communicating said openings with said central chamber.

Claim 10

Dependent Claim 18 words

The machine of claim 1 wherein said tip extends laterally entirely across a front side of said adapter.

Claim 11

Dependent Claim 127 words

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.

Claim 12

Dependent Claim 127 words

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.
