Filed: 1929-04-23
Abstract: 327,036. Llerß, I. S., and Corbatera, L. C. April 23, 1929. Lifting - cords and equivalents; shedding- motions; dobbies.-In order to avoid damage to the warp threads due to their friction on crossing, relative movement between a pair of ascending or descending healds, or between one or more healds and the rest of a group of healds is effected by suspending the healds from members passing around pairs of eccentric pulleys disposed symmetrically on the same spindle. In a calico loom, the odd - numbered warp threads 5, Fig. 1, are controlled by a pair of healds 1, 2 connected to a treadle 7 and suspended by members 9, 11 passing over eccentric pulleys 10, 12, the evennumbered warp threads being controlled in a similar manner. When the ascending motion of the healds 1, 2 begins, they are level, while at the middle of their path they occupy the positions shown in Fig. 5, and again become level when in their highest position. When the healds are controlled by a dobby, one heald 21, Fig. 2, at least of each group is connected to members passing around eccentric pulleys 22, other eccentric pulleys 23 on the same fixed shafts being connected to the levers 20 of the dobby,' while the other healds 19 of the group are connected directly to the levers.

Title: Improvements in or relating to mine gallery or like lining and supporting structures
IPC: E21D11/18
Filed: 1951-05-30
Abstract: 741,724. Mine gallery supports. MOLL, F. W., [trading as MOLL SOEHNE MASCHINENFABRIK, F. W.]. May 30, 1951 [Oct. 1, 1948; April 16, 1949]. No. 12741/51. Class 20(2). A mine gallery supporting structure comprises compression chambers containing granular ballast 13, openings being formed during subsidence of the structure under rock pressure, for the escape of this material. In Figs. 1 and 2 the gallery supporting arches 1 are supported on shoes 4 guided in rails 5-7 and resting on the material 13 and as the arch is forced, down by rock pressure knife edge rings 11 cut successively through timbers 10 between rails 5, 6 and the timbers fall and the ballast 13 escapes through the opening thus left. The rails 5-7 are held together by foot plate 8 and a top ring 9. The shoes 4 rest on runner rails 3 resting on the ballast 13. A second knife ring 12 provides increased frictional resistance to compensate for the easier discharge of the ballast at later stages of sinking of the structure. In a modification, Figs. 3 and 4, (not shown) the shoe embraces a single guide rail by side links and a connecting bolt and the rails 3 are hooked to the arches 1 and have slots engaged by tapered points in the shoes. In Fig. 5 the structure is supported above a rack wall 40, the shoe 38a is guided by lugs 38b and on the rail 5b and the timbers are replaced by U-section girders 10a which rest on planks 41, on top of the wall 40. Roof pressure transmitted through the arch 1, shoe 38a and girders 10a breaks the plank 41 and allows one girder to drop down the rail 5b and provide an opening for escape of the ballast 13, the remaining rails being held by the pressure of the ballast, until increasing pressure causes them to fall successively. A similar modification has timbers instead of girders and the shoe engages the timbers by a plate having openings to allow escape of ballast. In another modification Fig. 13 (not shown) the shoe 38a moves down behind the timbers which are broken successively by the pressure of the ballast. In another modification having girders Fig. 16 (not shown) the shoe moves down behind the upper girders until it engages the lower girders which are offset relative to the upper girders and are forced down producing an opening for escape of ballast between the upper and lower girders.
