Title: Earth-boring attachment for tractors
IPC: E21B7/02
Filed: 1946-07-18
Abstract: 614,605. Boring earth. FERGUSON, Inc., H. July 18, 1946, No. 21501. Convention date, Aug. 23, 1945. [Class 85] A post-hole boring attachment for a tractor comprises a frame pivoted to the tractor for vertical movement and having a groundengaging part, a boring member capable of vertical movement relative to the frame, and means for lowering the parts so that the frame engages the ground before the boring element. In Figs. 1 and 4, links 19, universally pivoted to a tractor T, are raised and lowered through links 21 and cranks 22 rocked, under control of a lever 24, by a hydraulic ram as in Specification 470,069, links 19 acting through rods 48 to rock an A-frame 42 pivoted to legs 28 of a tripod; the legs 28 are pivoted to the tractor and at their upper ends are fixed to a head frame 30 to which the third leg 29, adapted to engage the ground, is connected freely so as to take a vertical position. The auger 26 is driven from a power take-off shaft 25 through a telescopic shaft 60 and gearing in a housing 36 in which the auger is journalled; a square guide-rod 35, carried by the housing 36, is slidable in a square guide 38 forming a torqueresisting connection, the guide 38 being pivoted at 39 in a frame 40 pivoted at right angles to the pivot 39, whereby the boring assembly automatically takes a vertical position. A cable 53 passes over pulleys 54, 55, on the A- frame 42 and head frame 30 to anchorages on the housing 36; thereby, on lowering the A- frame, the boring assembly and tripod descend together until the leg 29 contacts the ground, the boring assembly afterwards descending alone. A projection 58 slidably co-operates with a bracket 57 on the housing 36 to prevent the leg 29 fouling the auger. Further, a telescopic arm 63 may connect the A-frame 42 and housing 36 to prevent rotation of the latter. Descent of the auger may be limited by inserting a pin in one of several holes 70 in the guide rod 35. In another form, Fig. 5, the A-frame is omitted, and the tripod leg 129 and auger assembly have universal mounting through balls 134, 138, to permit them to assume a vertical position ; telescopic members 71 are pivoted to the tractor and to a centrally pivoted rod on the housing 36, and are held by hooks 73 to a transverse member 72 connecting the ends of the links 19, whereby movement of the latter raises or lowers the boring assembly &c.

Filed: 1926-09-01
Abstract: 281,389. Constantinesco, G. Sept. 1, 1926. Power hammers. - Friction ratchet gearing, applicable for driving drop-hammers, &c., in which an automatic reverse is required, employs normally flat or slightly bent thin plates 5 of spring steel &c. arranged at an angle less than the angle of friction to radii of the oscillating and rotary members 3, 2 and separated by curved spring plates 6. The left-hand side of Fig. 1 shows the plates before they are crowded to working position as shown at the right-hand side, in which position the plates 5 are slightly curved by pressure. The oscillating member 3 is carried by rollers 4 on the driven shaft 1. which is secured to the member 2, or the plates may be arranged in groups separated by rollers which engage the members 2. 3. High-speed oscillation of the member 3 drives the member 2 in one direction, during which action the plates are alternately further flexed and released, until the load becomes excessive, when the plates are thrown over the dead centre and take up corresponding positions for driving the member 2 in the reverse. direction. As employed in drop hammers, the oscillator 3 is driven by a crank and elastic connecting-rod or by the apparatus described in Specification 185,022 [Class 80 (iii), Link-work &c.], and the rotor 2 drives a drum on which is wound the rope operating the hammer. When the hammer strikes a fixed stop. the plates reverse their position and the hammer falls. The drum is thus reversed to rewind the rope in the reverse direction and again raise the hammer.
