Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A drilling machine (10) having an elongated rectangular tower (12) with longitudinal frame beams (31), said tower being carried on a portable chassis (11) by forwardly directed lever track elements (25) mounted on the upper end of stanchion members (26) on said chassis, the rear end of each lever track element being pivotally mounted on a trunnion shaft (28) on a stanchion member, the track portion of each lever track element having a slot (29) to slidably hold and engage a shoe flange member (30) carried on the face of a longitudinal tower frame beam, said tower having a track means (17) for guiding both lengthwise and crosswise movement of a drill power means (16) with a rotating spindle (41) for connection to a section of drill pipe, said tower further having a magazine (18) for drill pipe pickup and storage.
Claim 2
Dependent Claim
141 words
A drilling machine (10) having an elongated rectangular tower (12) with longitudinal frame beams (31), said tower being carried on a portable chassis (11) by forwardly directed lever track elements (25) mounted on the upper end of stanchion members (26) on said chassis, the rear end of each lever track element being pivotally mounted on a trunnion shaft (28) on a stanchion member, the track portion of each lever track element having a slot (29) to slidably hold and engage a shoe flange member (30) carried on the face of a longitudinal tower frame beam, said tower having a track means (17) for guiding both lengthwise and crosswise movement of a drill power means (16) with a rotating spindle (41) for connection to a section of drill pipe, said tower further having a magazine (18) for drill pipe pickup and storage.
Claim 3
Dependent Claim
82 words
A drilling machine according to claim 1 wherein said drill power means has a head assembly (40) with end mounted track engaging rollers (59) and said track means includes a front channel (60), a transfer channel (61), and a rear channel (62), said rollers moving within said channels, said front channel guiding said head assembly during the operations of drilling and drill pipe subtraction and addition, said rear channel guiding said head assembly during the operations of drill pipe pickup and storage.
Claim 4
Dependent Claim
63 words
A drilling machine according to claim 2 wherein said magazine comprises a base mechanism for supporting and carrying drill pipe sections and a top structure to position a drill pipe section in relation to said rotating spindle, said base mechanism and said top structure extending crosswise of the tower and being spaced apart as determined by the length of the drill pipe sections.
Claim 5
Dependent Claim
41 words
A drilling machine according to claim 3 further having an upper clamp means (19) above said top structure of the magazine to selectively hold a drill pipe section while said head assembly is in said rear channel of the track means.
Claim 6
Dependent Claim
41 words
A drilling machine according to claim 3 further having a lower clamp means (20) below said base mechanism of the magazine to selectively hold a drill pipe section while said head assembly is in said front channel of the track means.
Claim 7
Dependent Claim
35 words
A drilling machine according to claim 3 further having an elevator means (21) for aligning a section of drill pipe being carried by said head assembly during the operations of drill pipe subtraction or addition.
Claim 8
Dependent Claim
103 words
A drilling machine according to claim 3 wherein said base mechanism of the magazine has a series of articulated socket elements (68) with an inner diameter slightly greater than the outer diameter of a drill pipe section and movable laterally of the tower in a closed loop, the medial portion of each socket member having oppositely directed link plates (69) for joining the socket members as a unitary structure, the upper end of each socket element having an elongated funnel (70) and the lower end of each socket element having an axially centered element (71) to resiliently support a section of drill pipe.
