Abstract
Abstract A multiple-spindle drilling machine is provided with a plurality of drilling spindle units each of which is driven from a common power supply means but which are readily adjustable longitudinally and normal to the drilling spindle axis to provide a multiplicity of drilling patterns as the plurality of units are advanced simultaneously to accomplish a drilling operation. A plurality of drilling spindle units may be adjustably mounted on a common support in a horizontal row and additional horizontal rows may be provided having the identical or different lateral spacing therebetween. The horizontal rows of spindles may be disposed parallel to each other or may be inclined relative to each other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
A multiple spindle drilling machine comprising a main base, a base plate slidably mounted on said main base, a plurality of drilling units each having support means and spindle means, said spindle means being rotatably and movably mounted on said support means in parallel to each other and being reciprocable along the axis of rotation thereof relative to said base plate, each of said units being slidably mounted on said base plate for movement transverse to said axis of rotation, means for selectively reciprocating each of said spindle means relative to said support means into and out of operative position and means for shifting said base plate on said main base in a direction parallel to said spindles to simultaneously advance and retract said units during a drilling operation.
Claim 2
Dependent Claim
129 words
A multiple spindle drilling machine comprising a main base, a base plate slidably mounted on said main base, a plurality of drilling units each having support means and spindle means, said spindle means being rotatably and movably mounted on said support means in parallel to each other and being reciprocable along the axis of rotation thereof relative to said base plate, each of said units being slidably mounted on said base plate for movement transverse to said axis of rotation, means for selectively reciprocating each of said spindle means relative to said support means into and out of operative position and means for shifting said base plate on said main base in a direction parallel to said spindles to simultaneously advance and retract said units during a drilling operation.
Claim 3
Dependent Claim
44 words
A multiple spindle drilling machine as set forth in claim 1 further comprising guide means on said main base and said base plate for guiding said base plate in the vertical direction and means for vertically reciprocating said base plate along said guide means.
Claim 4
Dependent Claim
29 words
A multiple spindle drilling machine as set forth in claim 1 further comprising means for locking each of said drilling units to said base plate at any desired position.
Claim 5
Dependent Claim
29 words
A multiple spindle drilling machine as set forth in claim 1 further comprising an additional drilling unit secured to said each first mentioned drilling units in vertical alignment therewith.
Claim 6
Dependent Claim
49 words
A multiple spindle drilling machine as set forth in claim 1 further comprising an additional base plate secured to and disposed in vertically spaced parallel relation to said first mentioned base plate and a plurality of drilling units slidably mounted thereon for movement transverse to said axis of rotation.
Claim 7
Dependent Claim
55 words
A multiple spindle drilling machine as set forth in claim 1 wherein said means for reciprocating each of said spindle means is comprised of cylinder means mounted on said support means, piston means reciprocable therein in opposite directions of the influence of pressurized fluid and means connecting said piston and spindle means for conjoint movement.
Claim 8
Dependent Claim
43 words
A multiple spindle drilling machine as set forth in claim 1 further comprising unitary drive means and a plurality of drive train means connected to said unitary drive means and each of said spindle means for imparting rotary motion to said spindle means.
