Projecting Figure 4 is a vertical transverse sectional from the peripheral face of the grooved porview of the device, on the line 44 of F igtion of. the member 18 is a lug 29 which is 1 ure 1. adapted to engage, at times with a lug 30 4O Referring particularly to the accompanyprojecting inwardly from'the inner face of v ing drawings, 10 re resents acylindrical casthe casing-10. Also carried by the inner ing which is provi ed with a removable clofaceof the casing adjacent the ring 23, are sure disk 11, in one end. Disposed within the diametrically opposite inclined cam lugs the casing is a member, represented as a 31, with which the radiating lugs 32, carried terminal spool portion 13, arranged outwardwhereby to cause the movement of sald ring ly of the casing, and the stem portion 14, longitudinally within the casing, as will be which is disposed longitudinally and centralclearly understood from an inspection of the 5 ly within the casing. The inner end of the drawings whole by the numeral 12, and comprising the by the ring 23, are adapted to be engaged,
spool portion is formed with a flange 15, on The otherend of the cable or wire 21 is 16 adapted to be connected with the wrench (not shown) which is used in unscrewing the drill rod, pipe, or the like sections.
In the operation of the device, the shaft 17 is in constant rotation, but if the clutch blades 24 are not in engagement with the lugs 16, the member 18, and the ring 23 will not rotate. Upon rocking the lever 27, to slide the ring 23, whereby to project the free ends of the blades 24 so that they will be engaged by the lugs 16, the member'j18, and-said ring will be rotated, with the result that the cable or wire 21 will be wound on the'said member, within the groove 20, pulling on the wrench so that an unscrewing action is imparted to'a section of the drill rod; The parts 18 and 23 are adapted tomake one complete turn, in this pulling action on the wrench, when the lugs 32' will'engage with the inclined lugs, .31, with the result that the ring 23 will be moved longitudinally on the'member 18, in a direction to withdraw the clutch blades 24 outof the path of the lugs, 16, thus permitting the member 12 to continue to rotate, while the member 18 is brought to a stop by engagement ofits lugs 29 with the lugs 80, of
th casing. It is understood thatthe wrench is swungto get a new grip on the drill rod section by any suitable means, as springs, or
byhand, but as this forms no part ofthe present invention, such is not illustatedr lpon the return movement of the wrench, the cable or wire 21- is pulled, whereby to unwind the latter from the member 18, which causes a retrograde rotation of such member, such rotation continuing. until the lug 29 again engages the lug 30, "which brings this rotation to an end. Upon again'swinging the lever 27, the wire 21 will be wound on the ,member 18, and'the wrench given another movement'toimpart an unscrewing action on the. drillirod' section. This is continued until'the'drill rod sections have beencome pletely separated, or unscrewed sufficiently to permit the operator to complete the opera 'tion by handor machinery.
