  • TRACK-PACKING MACHINES Im/anton' Fard/nana Schne//mann By /'s affome y 7M@ www United States Patenti() TRACK-PACKING MACHINES Application February 27, 19s3, ⁇ seria1 No. 339,434
  • the present invention is for improvements in track- "7 packing machines for packing ballast'un'der the Vsleepers of railway rails. It is essential in the packing oepration to ensure that the ballast is packed uniformly mosaicfashion under that part of the sleeper which supports the rail.
  • the packing tools are arranged at both sides of the rails and are constructed as picks with packing plates which penetrate into the ballast located alongside the sleepers and are moved towards one another by means of mechanically driven threaded spindles, the pivot point of the packing arms with connected picks remaining at an invariable distance from an eccentric shaft producing the vibrations.
  • the present invention overcomes this diiculty by providing that packing assemblies are arranged in connection with a travelling track-packing machine, with which assemblies the arms with connected picks can be shifted to any desired inclined position so that they force, in the manner of tongs, the ballast under that part of the sleeper which supports the rail.
  • a track-packing machine wherein the pick holders are pivotally mounted substantially at their centre point and are connected with one another in opposition at their upper ends.
  • Figure 1 illustrates a side elevation of the complete machine
  • Figure 2 illustrates a front elevation of Figure l, in the direction of the ⁇ arrow therein;
  • Figure 3 illustrates a plan view of a packing box
  • Figure 4 illustrates a side elevation of the packing box
  • Figure 5 illustrates a section on the line A--A in Figure 4.
  • Figure 6 illustrates a view on the line B-B in Figure 4.
  • Figure 7 illustrates a control diagram for the actuation of the packing assemblies
  • Figure 8 illustrates a diagram of the control block and slide
  • Figure 9 is a diagram which illustrates the electrical installations of the complete track-packing machine.
  • Xa frame 1 of ⁇ a track-packing machine is moved on rails 2 by means of two pairs of wheels 3 and 4 between which there is disposed a packing box 5 which is raised and lowered on a column 6 and a slide rail 7.
  • Upward and downward movement of the packing box 5 is effected by the friction wheels 9 c 2,791,971 ICC being driven by means of an electric motor 8.
  • the friction wheels 9 ' are made to bear by means of springs upon vertical draw bars 10 to which the packing box 5 is rigidly connected.
  • the said packing box 5 When travelling to and from the place of work, the said packing box 5 is suspended and secured by means of a hook 11 which engages around a pin 12, the said hook serving, when the packing operation is in progress, as a stroke-limiting means in the upward movement of the packing box 5, the release of the hook 11 being effected by means of a lever 13.
  • pick holders 14 Arranged on the packing box 5 are pick holders 14 into which are fitted picks 15 and packing plates 15' are mounted upon the lower ends ofthe said picks.
  • the pick holders 14 are pivotally mounted near their midpoints on a cross-head 16. At their tops they are each pivotally connected, by means ⁇ of an intermediate link 17, with a pressure ram 18 by bolts 19.
  • the two pressure rams 18 are guided by means of the pressure cylinder 20.
  • the cross-head 16 is pivotally connected with an eccentric 23 ( Figure 1) by means of a pin 21 and a connecting rod 22, the said eccentric being driven by means of a rotating shaft 24 and the mounting of the cross-head 16 being effected by means of a pair of guide shafts 25.
  • the eccentrics 23 cause a sliding movement which is transmitted to the cross-head 16 by way of the connecting rod 22.
  • the rotating shaft 24 is driven by an electric motor 26 by way of V-belts 27, the s-aid shaft driving a pump 29 by means of a pair of gear wheels 2S, said pump serving to feed the pressure cylinder 20, the oil being drawn from the tank 30.
  • the electric motors 8, 26 and a further electric motor 33 are fed by a generator which is driven by a diesel engine 32.
  • the movement of the track-packing machine is effected by driving the pair of wheels 4 by means of the electric motor 33.
  • the first movement is the lowering of -the packing box 5.
  • the picks 15 together with the packing plates 15' lare then forced into the ballast to such an extent that the packing plates 15' in their final position are beneath the base of the sleeper.
  • the opening and closing movements are effected by oil by means of the pressure cylinder 20 and pressure ram 18, each pair of the picks 15 operating independently, which is not the case with known track-packing machines.
  • the pick holders 14 and the picks 15 have imparted thereto, by means of the eccentric 23, a continuous shaking movement so that both the lowering of the packing plates into the ballast takes place more easily and, during the packing operation, the ballast does not become wedged.
  • the opening and closing of the packing tools is elected by a hand lever 43 ( Figure 2) through a control block 34 provided with a slide valve 35, one embodiment of the control block being illustrated in Figure 8.
  • a hand lever 43 Figure 2
  • a control block 34 provided with a slide valve 35, one embodiment of the control block being illustrated in Figure 8.
  • oil is drawn from the tank 30 through the pipe 36 and forced by way of the pipe 37 to the control block 34, which comprises two horizontal and two vertical bores. ln the control slide valve, there are only two bores which are staggered by A pressure regulating valve 38 is fitted in the pipe 37 between the pump 29 and the control block 34.
  • Figure 9 illustrates diagraunnatically the electrical vin-r stallation of the vcomplete track-pa'clring'machine, in which a diesel engine 32 drives av generator 31, the main cable 44 being led lo a distributor 45, which comprises four switches 46, 47, 48 and 49. l
  • a cable 50 leads from the switch 48 by way vof a footoperated reversing switch 51 and conduits 52 to the two motors 8, which change their direction of rotation accordandl mechanical means connected to the pivots to shake ing to whether the packing box S is to be raised or lowered.
  • Switches 53 are included for switching 01T each separate assembly. Cables 54 and 5S lead from the switches 47 and 49 to the two motors 26, which drive the eccentric shaft 24. A cable 56 leads from the switch 46 byway of a stop switch 57 to the motor 33 which drives the rear wheels.
  • a track-packing machine Ahaving opposed pick holders, picks in said holders, horizontal pivots vfor lthe holders near ⁇ the midpoints of the latter and 'transverse of the machine about which pivots the holders are movable,
