Abstract: An apparatus and method for slicing roofing material includes a prime mover in the form of a powered tractor, and a slicing assembly mounted to the rear end of the tractor. The slicing assembly includes a frame mounted to the tractor, a blade mounted to the frame, and a raising and lowering assembly for raising and lowering the rear end of the tractor, which in turn controls the position of the blade relative to the roof. The raising and lowering assembly includes a support member such as a wheel, and is pivotably mounted to the frame for movement between a raised position, providing penetration of the blade into the roofing material, and a lower position for maintaining the blade above the roofing material. A retainer mechanism is interconnected between the frame and the support assembly for selectively maintaining the support assembly in its lower position. A stop assembly is interconnected with the frame for controlling the angular position of the support assembly relative to the frame, to thereby control the amount of vertical movement of the support assembly relative to the rear end of the tractor and the amount of penetration of the blade into the roofing material.

Abstract: A continuous-operation extraction apparatus for strip mining that is self propelled on continuous track treads. A cylindrically-shaped cutting extractor has cutting tools arranged on its peripheral surface. Recesses are provided in this peripheral surface for the transfer of extracted material through a chute to a first conveyor that is located axially within the cylinder of the cutting extractor. A second conveyor having loading carts connects with the first conveyor and receives the loosened material from the first conveyor. The first conveyor has an inside section which emerges from a front side of the cylinder and merges outside into a sloping conveyance section which extends vertically to substantially an upper edge of a chassis. An overhead ascending section is connected to the inside section and terminates in a transfer region where the extracted material is transferred to the second conveyor.

Abstract: A self-propelled grinding or milling apparatus for finishing a surface of concrete or similar hard material such as a floor, which includes a frame supported on a number of wheels. A rotating grinding or milling tool is mounted in the frame and has a vertical shaft which is suspended and loaded with weights so that the pressure of the wheels on the surface is maintained at a constant level at varying working pressures of the tool. The apparatus is arranged to tilt laterally by means of a raising and lowering device which acts on the non-steerable wheels so that the pressure of the tool on the floor differs on the right-hand and left-hand side of the apparatus and so gives rise to frictional forces which cause the apparatus to move either in the forward direction or the rearward direction at a speed which is dependent on the magnitude of the tilt.

Abstract: A continuing mining machine wherein a crusher is placed inboard of the machine and has a dipper machanism as well as a loading chute. The dipper is of a twin handle type so that it can straddle a feeder chute thus affording a wide area for excavating. The placement of the crusher in a central location within the machine allows for stability and obviates the need for swivelling of the crusher during operation of the machine.

Abstract: With cutting machines, having their loading means (7) adapted to be lowered below the running surfaces (11) of the crawlers (2) of the drift advancing machine, there results an erroneous position of the machine on account of lifting the front end of the machine during such lowering movement of the loading means (7). For establishing the correct position of the cutting tool (6) and of the cutting arm (5), corrective signal are used which are released by angular position transmitters (16 or 17, respectively). By means of these angular position transmitters (16 or 17, respectively), the swivelling angle of the loading means (7) relative to the frame (1) or the swivelling angle .theta. of the operating cylinder (9) of the loading means (7) relative to the frame (1), respectively, is measured and the required corrective signal for the angle advance .DELTA..alpha. is calculated (FIG. 3).

Abstract: In accordance with the invention, the stemming of blast holes, i.e. the covering (with peviously removed earth materials) of explosive charges placed in receiving boreholes drilled downwardly from generally horizontal surfaces in open-pit mines, involves the proper manipulation of a special vehicle relative to earth material cuttings that collect concentrically about the mouth of such a borehole during the drilling operaton. The vehicle carries a combination of earth-moving blades that can be raised and lowered as a unit and that comprises a transverse pusher blade mounted on one end of the vehicle and a pair of elongate auxiliary blades pivotaly mounted on and in mutually spaced relationship transversely of the pusher blade as arms which can be swung toward and away from each other. The auxiliary blades have respective tip portions turned toward each other, and are preferably arranged to stop short of meeting when swung together so as to accommodate the blast cord between such tip portions. In carrying out the method, the vehicle with auxiliary blades extended outwardly is moved directly toward and to the hole, so the pusher blade will engage and push drill cuttings into the hole from the front; the auxiliary blades are then swung together for pushing drill cuttings into the hole from its opposite sides; and then, without retracting the auxiliary blades, the vehicle is backed away from the hole, so the tip portions of the auxiliary blades will pull drill cuttings into the hole from the rear.
