Mine drilling machine

Claim 2

IN A DRILLING MACHINE, THE COMBINATION COMPRISING AN ELONGATED GUIDE FRAME PROVIDING LONGITUDINAL GUIDING MEANS, A ROTARY DRILLING IMPLEMENT EXTENDING LENGTHWISE OF SAID GUIDE FRAME FOR ENDWISE MOVEMENT ALONG SAID GUIDING MEANS, DRIVING MEANS FOR SAID DRILLING IMPLEMENT FOR ROTATING THE LATTER, A ROTARY GUIDE MEMBER ROTATABLY MOUNTED ON SAID GUIDE FRAME IN SPACED RELATION TO SAID DRIVING MEANS TO SUPPORT SAID DRILLING IMPLEMENT AND THROUGH WHICH SAID IMPLEMENT EXTENDS AND IS AXIALLY MOVABLE, SAID ROTARY GUIDE MEMBER BEING ARRANGED IN PARALLEL RELATION TO SAID DRILLING IMPLEMENT, AND MEANS COORDINATED WITH SAID DRIVING MEANS FOR ROTATING SAID GUIDE MEMBER IN THE SAME DIRECTION AND AT THE SAME ANGULAR SPEED AS THE SPEED OF ROTATION OF SAID DRILLING IMPLEMENT.

Claim 3

IN A DRILLING MACHINE, THE COMBINATION COMPRISING A GUIDE FRAME HAVING PARALLEL SIDE MEMBERS, FRONT AND REAR CROSS MEMBERS POSITIONED BETWEEN SAID SIDE MEMBERS ADJACENT THE RESPECTIVE END PORTIONS OF SAID SIDE MEMBERS THEREBY MAINTAINING SAID SIDE MEMBERS IN SPACED PARALLEL RELATION TO EACH OTHER AND FORMING A LONGITUDINAL GUIDEWAY THEREBETWEEN, A CARRIAGE TRAVERSABLE LONGITUDINALLY WITHIN SAID GUIDEWAY, AN AUGER EXTENDING LENGTHWISE IN SAID GUIDEWAY, SAID CARRIAGE HAVING MEANS TO ENGAGE THE SHANK END PORTION OF SAID AUGER, FIRST GEAR MEANS WITHIN SAID CARRIAGE OPERABLE UPON ROTATION TO ROTATE SAID AUGER, MEANS FOR MOVING SAID CARRIAGE LONGITUDINALLY IN SAID GUIDEWAY, A ROTATABLE AUGER SUPPORTING SLEEVE MOUNTED ON SAID GUIDE FRAME FRONT CROSS MEMBER, SECOND GEAR MEANS CONNECTED TO SAID SLEEVE AND OPERABLE UPON MOVEMENT TO ROTATE SAID SLEEVE, SPLINED SHAFTING ROTATABLY SUPPORTED BY SAID FRONT AND REAR CROSS MEMBERS, A MOTOR MOUNTED ON SAID GUIDE FRAME INTERMEDIATE ITS END PORTIONS, DRIVING CONNECTIONS BETWEEN SAID MOTOR AND SAID SPLINED SHAFT AND BETWEEN SAID SPLINED SHAFT AND BOTH OF SAID FIRST NAMED AND SECOND NAMED GEAR MEANS SO THAT SAID SUPPORTING SLEEVE WILL ROTATE IN THE SAME DIRECTION AND AT THE SAME ROTATIONAL SPEED AS THAT OF SAID AUGER IRRESPECTIVE OF THE RELATIVE LONGITUDINAL POSITION OF SAID CARRIAGE IN SAID GUIDE FRAME GUIDEWAY, AND MEANS ASSOCIATED WITH SAID REAR CROSS MEMBER TO MAINTAIN SAID SPLINED SHAFTING OPERATIVELY ALIGNED WITH SAID DRIVING CONNECTIONS BETWEEN SAID SHAFTING AND SAID FIRST AND SECOND GEAR MEANS.

Claim 4

IN A DRILLING MACHINE, THE COMBINATION COMPRISING A GUIDE FRAME HAVING PARALLEL SIDE MEMBERS, FRONT AND REAR CROSS MEMBERS POSITIONED BETWEEN SAID SIDE MEMBERS ADJACENT THE RESPECTIVE END PORTIONS OF SAID SIDE MEMBERS THEREBY MAINTAINING SAID SIDE MEMBERS IN SPACED PARALLEL RELATION TO EACH OTHER AND FORMING A LONGITUDINAL GUIDEWAY THEREBETWEEN, A CARRIAGE TRAVERSABLE LONGITUDINALLY WITHIN SAID GUIDEWAY, AN AUGER EXTENDING LENGTHWISE IN SAID GUIDEWAY, SAID CARRIAGE HAVING MEANS TO ENGAGE THE SHANK END PORTION OF SAID AUGER, FIRST GEAR MEANS WITHIN SAID CARRIAGE OPERABLE UPON ROTATION TO ROTATE SAID AUGER, MEANS FOR MOVING SAID CARRIAGE LONGITUDINALLY IN SAID GUIDEWAY, A ROTATABLE AUGER SUPPORTING SLEEVE MOUNTED ON SAID GUIDE FRAME FRONT CROSS MEMBER, SECOND GEAR MEANS CONNECTED TO SAID SLEEVE AND OPERABLE UPON MOVEMENT TO ROTATE SAID SLEEVE, SPLINED SHAFTING ROTATABLY SUPPORTED BY SAID FRONT AND REAR CROSS MEMBERS, A MOTOR MOUNTED ON SAID GUIDE FRAME INTERMEDIATE ITS END PORTIONS, DRIVING CONNECTIONS BETWEEN SAID MOTOR AND SAID SPLINED SHAFT AND BETWEEN SAID SPLINED SHAFT AND BOTH OF SAID FIRST NAMED AND SECOND NAMED GEAR MEANS SO THAT SAID SUPPORTING SLEEVE WILL ROTATE IN THE SAME DIRECTION AND AT THE SAME ROTATIONAL SPEED AS THAT OF SAID AUGER IRRESPECTIVE OF THE RELATIVE LONGITUDINAL POSITION OF SAID CARRIAGE IN SAID GUIDE FRAME GUIDEWAY, AND MEANS ASSOCIATED WITH SAID REAR CROSS MEMBER TO MAINTAIN SAID SPLINED SHAFTING OPERATIVELY ALIGNED WITH SAID DRIVING CONNECTIONS BETWEEN SAID SHAFTING AND SAID FIRST AND SECOND GEAR MEANS.
