  • a carriage 8 runs on wheels 9 on the traveling crane member 6.
  • FIG. 4 shows that the wheels 9 are adapted to be guided on the traveling crane member 6 and are driven by a motor 10 over an appropriate transmission 11.
  • the transmission is dimensioned in such manner that carriage 8 will move at the same rate along the traveling crane member 6 as that at which the entire machine in accordance with FIGS. 1, 2, and 3, respectively, will move along the rails.
  • FIGS. 4 and 5, respectively, are elevational views taken at 90 from each other, and these figures show that carriage 8 carries a pressurized container 12, which is intended for dry concrete and which at its top has a sealing cover 35 that may be opened inwardly into the container.
  • container 12 is provided with a feed-out wheel which is driven by a motor 13. Said feed-out wheel continuously feeds dry concrete to an output opening having a hose 14 connected thereto, through which dry concrete is blown out by means of compressed air.
  • a pump 17 for example an adjustable deplacement pump, is driven by the same shaft as said feed-out wheel and urges water from a container 16 through a hose 18 out into an annular nozzle 15 which opens into said hose 14.
  • the water is mixed with the dry concrete so as to provide the latter with desired consistency, whereafter the completed concrete is blown out through a nozzle 19 down into a molding head 20 comprising two parallel sides that are connected at the top but are open at the bottom.
  • the concrete is packed by a ramming device which is illustrated more specifically in FIGS. 6 and 7, respectively.
  • the machine may be provided with two rams, each comprising a twoway operative compressed air cylinder having two hammers being alternately displaced upwards and downwards, respectively, between the two sides of the molding head 20 so as to pack the concrete.
  • the ramming device will be disclosed more specifically below.
  • the molding head 20 As said molding head 20 moves forwardly, it leaves behind a strip of packed concrete having a rectangular cross-section. In order to decrease the friction between the concrete and the sides of molding head 20, the latter sides are designed such, that the greater part of their area is composed of a round disc 36 (FIGS. 5 and 7, respectively), which may rotate around a shaft 360. As may be seen from FIGS. 4 and 5 the molding head 20 is adapted to be displaced in a horizontal and straight path along the lower edge of an operators cabin 37 positioned below container 12 by means of a wheel 38 running along a track 39, with said wheel 38 being mounted on molding head 20.
  • molding head 20 is guided by linkage arms 40a and 40b, respectively, which are connected to said molding head 20 and to a plate 41, which latter is displaceable vertically on guides in the operators cabin 37.
  • a pivot arm 42 is also connected to plate 41. Said pivot arm may pivot between the linkage arms 40a and 40b and in the same plane as the latter.
  • the pivot arm 42 is shown on an enlarged scale in FIG. 6, in which it may be seen that a support 43 for the above-mentioned ramming device 21 is rotatably mounted at the lower portion of pivot arm 42.
  • a rotational movement of a handle 48 may be transferred to support 43 over a bevel gear 44, a shaft 45, a gear 46 and a shaft 47.
  • the handle 48 is prevented from moving freely as the result of friction against a disc 49, which over a transmission is connected to a motor 50 provided with a magnetic brake.
  • pivot arm 42 may pivot without the angle of the support 43 being altered with respect to plate 41.
  • Support 43 is provided with guides 51a and 51b, respectively, for the hammers of the ramming device, which latter thus may move upwards and downwards in consequence of said guides.
  • a rotatable distribution valve 52 for supplying compressed air to the ramming device 21 alternately flows compressed air into a cylinder (FIGS.

  • Three relief valves 66, 67, and 68, respectively, are connected in parallel behind valve 65.
  • From relief valve 66 the compressed air flows through a valve and a tube 70 to the container 12 (FIG. 5) for material.
  • From relief valve 67 the air flows through a magnetic valve 71 to a shut-off device 72 for hose 14 (FIG. 4) and over a magnetic valve 73 through a tube 74 to cylinders 75 and 76 in FIGS. 6 and 7, respectively.
  • From relief valve 68 the air flows through a magnetic valve 77 and an oil mist lubricating device 78 through a tube 79 to valve 52 and from there onto ramming device 21 (compare FIGS. 6 and 7, respectively).
  • An additional motor 80 is provided at the lower portion of the operators cabin 37 (FIG. 5) and runs a belt or a band 82 over rollers 83 and 84 by means of a transmission 81.
