摘要： 799,739. Mine roof support bars. EGGEMANN, WW., and CAMPENHAUSEN, E. VON, '[trading as SCHWARZ KOMMGES., H.]. Aug. 17, 1955 [Aug. 19, 1954], No. 23733/55. Class 20(2) In mine roof support bars engaging end to end by a tongue 25 and a fork 16 connected by a pin 20 and locked by a wedge 29, the pin 20 engages a slot 31 extending longitudinally of the tongue 25. The wedge 29 engages slots 20 in the fork and one of two recesses in the end of the tongue. In a modification, the inner end of the slot 31 is enlarged to form recesses to accommodate the pin 20 and lock the bars against longitudinal movement. In another modification, . the pin is formed with flats which fit the slot 31 which has an enlarged inner end in which the pin can be turned so :that the flattened end is at right angles to the slot and locks the pin and bars in position.

摘要： 750,229. Mine roof supporting bars. GUTEHOFFNUNGSHUTTE STERKRADE AKT.- GES., [formerly GUTEHOFFNUNGSHUTTE OBERHAUSEN AKT.-GES.]. Jan. 28, 1953 [Jan. 28, 1952], No. 2472/53. Addition to 738,819. Class 20(2). The pivot joint between two mine roof bars described in the parent Specification is modified in that the pivot eye 3, Figs. 1, 2 on one bar 1 which receives the pin 4 of the advance bar 2 is provided on a plate 18 mounted on a vertical axis 16 on the bar 1 for lateral rotatable movement. Alternatively the eye 31, Figs. 7, 8 is provided with an arcuate bearing surface 60 at its outer end, the pin 4 on the bar 2 being first rested on the bottom flange of the bar 1 adjacent the eye 3 1 with the bar 2 in a laterally inclined position, whereupon the bar 2 is pivoted upwards and a locking bolt 51 on the bar 2 with an arcuate end piece 50 1 slid forwards to engage the bearing surface 60 as shown in Fig. 8, the bar 2 then being swung horizontally into line with the bar 1, so that the pin 4 engages in the eye 3 1 as shown in Fig. 7. Fig. 7 also shows the locking bolt 51 retracted and a locking wedge 28 supporting the bar 2. An apertured abutment plate 14, Figs. 1, 2 provided. on the end of the bar 1 limits the lateral movement of the plate 18, the pin 4 of the bar 2 also passing through the aperture 17. A longitudinally displaceable locking bolt 5 on the bar 2 engages in a recess 6 in the plate 18 to hold the bar 2 in the horizontal plane while swinging it into line with the bar 1. A locking shoe wedge 8, Fig. 4, guided by the lower flange of the bar 1 is then driven over the extremities of the pin 4 on the bar 2.

摘要： 775,754. Roof-supporting bars in mines. GUTEHOFFNUNGSHUTTE STERKRADE AKT.-GES., [formerly GUTEHOFFNUNGSHUTTE OBERHAUSEN AKT.-GES.] Dec. 18, 1952 [Jan. 16, 1952], No. 32130/52. Class 20(2) In order to provide large range of angular movement of an advance mine roof bar 2 pivoted on a propped bar 1 using a single horizontal transverse wedge 4 passing through and engaging a slot 9 in the bar 2 the end of the bar 1 is formed as a toothed segment 5 and teeth 11 on the wedge 4 are engaged selectively higher or lower in the segment 5 according to the angular position required for the bar 2. The teeth 11 are inclined lengthwise with respect to the upper bearing edge of the wedge 4 in such a way that the bar 2 is tilted upwardly as the wedge is driven in. The wedge 4 is perpendicular to the longitudinal axis of the bar 2 but it may be arranged to extend at an acute angle to the bar axis to provide larger bearing surfaces for the teeth 5, 11.

摘要： 760,654. Mine roof supports. DIRECTIE VAN DE STAATSMIJNEN IN LIMBURG. Oct. 25, 1954 [Oct. 29, 1953]. No. 30683/54. Addition to 709,240. Class 20(2) In a roof supporting structure for mines, an advance girder 3 is supported against the roof, cantiliver fashion, from a girder 1 already in position, by a cap shoe 9 which is provided with inwardly directed projections 10 enabling the shoe 9 to be suspended from the bottom flanges 7 of the girder 1 and displaced therealong until the projections 10 engage faces 12 raised from the level of the bottom flanges 7, in which position of the shoe, a thrust screw 19 is operated to thrust the girder 3 against the roof. The cap shoe may be applied to the girder 1 to rest upon the flanges 7, by sliding it over the end of the girder, or by passing the projections 10 through recesses 8 in the flange 7. The cap shoe 9 may be mounted either with the screw 19 beneath the advance girder 3 as shown, or beneath the girder 1. The girders 1 and 3 are connected by a pin 4 on the girder 3 engaging, a hole 2 in the girder 1, and a sliding bolt, Fig. 2 (not shown), provided on the girder 3 to secure the connection. Specification 709,241 is referred to.
