Abstract
Abstract An automatic drilling machine including a hopper for spindles or the like to be fed one by one into the working area; a plurality of automatic drill heads; and clamping means for the spindles to position them with reference to the drills, each drill being adjustable both as to its position of action with respect to the spindle, its angle, and the length or depth of hole to be drilled. The machine also includes cutoff saws, chucking means, and a new and improved feed device for the spindles, and control means for the operation of all the tools, said control means being dependent on the position of the spindle feed device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
236 words
Automatic drilling machine for drilling a plurality of generally related bores in a spindle, comprising a gravity hopper holding and releasing the spindles one by one, a reciprocating feeder including means receiving the lowermost spindle in the hopper when retracted and moving the same forwardly to the working area, means at the working area receiving and clamping the spindle; a plurality of automatically actuated upper drill heads and a rear drill head, each drill head, including a motor for rotating the drill and means for reciprocating the drill to and from the work area for cutting bores in the spindle, means for supporting each upper drill head, said supporting means being adjustable in a direction longitudinally of the spindle when it is at the work area, means to adjust said drill heads vertically, means to adjust said drill heads at an angle with respect to the axis of the spindle in a plane parallel to the axis of the spindle; another support for the rear drill head, this latter support being angularly adjustable and having a center at the axis of the spindle in the work area, said latter support including means for longitudinal and lateral adjustment in respect to the axis of the spindle in the work area; and control means cycling the operation of the drills both as to rotation and reciprocation thereof, said means being controlled by the position of the spindle feeder.
Claim 2
Dependent Claim

Automatic drilling machine for drilling a plurality of generally related bores in a spindle, comprising a gravity hopper holding and releasing the spindles one by one, a reciprocating feeder including means receiving the lowermost spindle in the hopper when retracted and moving the same forwardly to the working area, means at the working area receiving and clamping the spindle; a plurality of automatically actuated upper drill heads and a rear drill head, each drill head, including a motor for rotating the drill and means for reciprocating the drill to and from the work area for cutting bores in the spindle, means for supporting each upper drill head, said supporting means being adjustable in a direction longitudinally of the spindle when it is at the work area, means to adjust said drill heads vertically, means to adjust said drill heads at an angle with respect to the axis of the spindle in a plane parallel to the axis of the spindle; another support for the rear drill head, this latter support being angularly adjustable and having a center at the axis of the spindle in the work area, said latter support including means for longitudinal and lateral adjustment in respect to the axis of the spindle in the work area; and control means cycling the operation of the drills both as to rotation and reciprocation thereof, said means being controlled by the position of the spindle feeder.
Claim 3
Dependent Claim
23 words
The machine of claim 1 including means reciprocating said feeder so that the reciprocation of the feeder controls the operation of the drills.
Claim 4
Dependent Claim
40 words
The machine recited in claim 1 including chucking devices in line with the means for holding the spindle in the working area, and means for reciprocating said chucking devices toward and away from each other to operate on the spindle.
Claim 5
Dependent Claim
65 words
The machine recited in claim 1 including chucking devices in line with the means for holding the spindle in the working area, and means for reciprocating said chucking devices toward and away from each other to operate on the spindle, means for rotating said chucking devices, the rotation and the rectilinear motion of said chucking devices including control means therefor actuated by said spindle feeder.
Claim 6
Dependent Claim
38 words
The machine of claim 1 wherein said spindle feeder comprises a pair of separate spaced vertical plates, said plates being free-ended, means for moving vertically the free ends of said plates, the rear ends thereof being pivotally mounted.
Claim 7
Dependent Claim
97 words
The machine of claim 1 wherein said spindle feeder comprises a pair of separate spaced vertical plates, said plates being free-ended, means for moving vertically the free ends of said plates, the rear ends thereof being pivotally mounted, and means controlling the operation of said last-named means so that said plates are in their uppermost position as they move forwardly under the hopper and receive the lowermost spindle therein continuing in this condition until the work area is reached and then dropping to position the spindle at the work clamp, and then retreating to repeat the cycle.
Claim 8
Dependent Claim
21 words
The machine of claim 1 including means controlled by the position of said spindle feeder for operating the spindle clamping means.
Claim 9
Dependent Claim
66 words
The machine of claim 1 wherein the spindle feeder comprises a pair of vertical spaced plates, said plates being at least partially vertically movable during the reciprocation thereof, and means at corresponding ends of the plates to receive and hold a spindle from the hopper while in an uppermost position, the top edges of the vertical plates maintaininG the remainder of the spindles in the hopper.
Claim 10
Dependent Claim
91 words
The machine of claim 1 wherein the spindle feeder comprises a pair of vertical spaced plates, said plates being at least partially vertically movable during the reciprocation thereof, and means at corresponding ends of the plates to receive and hold a spindle from the hopper while in an uppermost position, the top edges of the vertical plates maintaining the remainder of the spindles in the hopper, and pneumatic means to raise and lower the plates cyclically accepting any spindle within the machine specifications at the point of contact with the spindle.
Claim 11
Dependent Claim
54 words
The machine of claim 1 including means for adjusting the upper drill heads as a unit relative to the rear drill head, and means to adjust the upper drill heads laterally with respect to the axis of the spindle to bring the axes of the drill bits through the center of the spindle axis.
