Block with coolant delivery

A block for use in a cutting assembly wherein the cutting assembly comprises a driven member, a coolant source, and a cutting bit assembly, the block comprising:

• a block body having a bottom face, a top face, a forward face, and a rearward face;
• the block body containing a retention bore adapted to receive a cutting bit, and the retention bore having a retention bore central longitudinal axis;
• the block body containing a reservoir at the bottom surface wherein the reservoir is in communication with the coolant source so as to receive coolant from the coolant source;
• the reservoir having a forward reservoir outlet and a rearward reservoir outlet;
• the block body containing a bottom passage having an axial forward bottom passage end and an axial rearward bottom passage end, the axial rearward bottom passage end being at the forward reservoir outlet of the reservoir whereby the bottom passage receives coolant from the reservoir through the forward reservoir outlet and the axial rearward bottom passage end, and the bottom passage containing a bottom passage threaded region adjacent the axial forward bottom passage end;
• the block body containing a rear passage having a top rear passage end and a bottom rear passage end, the bottom rear passage end being at the rearward reservoir outlet whereby the rear passage receives coolant from the reservoir through the rearward reservoir outlet and the bottom rear passage end;
• the block body containing a top passage having an axial forward top passage section terminating in an axial forward top passage end, and the axial forward top passage section having an axial forward top passage section central longitudinal axis;
• the top passage further having an axial rearward top passage section terminating in an axial rearward top passage end, and the axial rearward top passage section having axial rearward top passage section central longitudinal axis;
• the axial forward top passage section central longitudinal axis is disposed at an angle with respect to the axial rearward top passage section central longitudinal axis;
• the top rear passage end intersects the top passage in the axial rearward top passage section;
• the axial rearward top passage section containing a rearward top passage threaded region adjacent the axial rearward top passage end, the axial forward top passage section containing a forward top passage threaded region adjacent the axial forward top passage end;
• and
• the block body containing retention staple holes adjacent the axial forward top passage end.

A block-sleeve assembly for use in a cutting assembly wherein the cutting assembly comprises a cutting bit, a driven member and a coolant source, the block-sleeve comprising:

• a sleeve being non-rotatable relative to the block, and the sleeve having a sleeve body with a head portion that contains a sleeve notch;
• a block body containing a reservoir with coolant therein;
• the block body further containing a top passage, and the top passage being in operative communication with the reservoir so as to receive coolant from the reservoir;
• the top passage having an axial forward top passage section terminating in an axial forward top passage end;
• the block body containing a block notch adjacent to the axial forward top passage end;
• and
• wherein the block notch being in alignment with the sleeve notch to facilitate the flow of coolant from the top passage.
