A power driven motive, and which is adapted to move along a conveyor is preferably used to positively move .55 platform to successive operating positions fordethe ice cakes along the platform. and such a conveyor may consist of an endless chain i9, suitably supported in a groove or slot in the platform between the runners H. The chain I9 is provided with upstanding lugs 20 spaced along its length at suitable intervals to engage and propel the blocks of ice I5 along the platform.
To guide the movements of the mobile elevator and crusher along the platform I 4, the latter is also provided with a longitudinal pair of parallel rails 2| which may be of railroad type and which are supported in the platform structure, so that the upper surface of the rails is approximately flush with the upper surface of the platform. Suitable stops or bumpers 22 may be provided at the end of each rail 2| Referring now to Figures 2, 3, and 4, showing in detail the preferred embodiment of portable elevator and ice crusher of this invention, the supporting frame of the machine is indicated by the numeral 26. It is generally rectangular in shape, and may, e. g., be fabricated from structural steel members rigidly secured together by bolts, welding, or the like. The frame 26 is supported for movement along the platform on wheels 21, each wheel having a short or stub axle 28, journaled in suitable bearings 29, secured with reference to the frame 26 by braces or pedestals 30. The bearings 28 are arranged on both sides of and relatively close to each wheel so that the frame 26 may be supported on these wheels without the use of transverse axles extending from one side of the device to. the other. A relatively large clearance is thereby provided beneath the frame 26, so that the device may easily straddle or pass blocks of ice on the platform. The wheels 2'! are provided with a pe-- ripheral flange to maintain the wheels on the rails 2| during longitudinal movement of the device along the platform to any desired location. Obviously, rails 2| may be omitted and plain unflanged wheels be used for operation of the device along the surface of the platform, if de-- sired.
The upper ends 3| of an inclined elevator or conveyor 32 are pivotally supported above the frame 26 on a horizontal shaft 33 journaled in the upper ends of the vertical frame members 34. The lower portion 4| of the elevator 32 is supported by the tension cables 35 which are adapted to be wound on the drums 36 suitably secured to a jack shaft 31 journaled in upright frame members 38. Rotation of the shaft 31, for instance, by the use of a geared electric motor 39 and a chain drive 40, causes the cables 35 to be wound or unwound on the drums 36 for lifting or lowering the lower portion 4| of the elevator 32. The lifted position of the elevator is shown by dotted lines in Figure 3.
The elevator 32 is preferably of the endless chain type, having a chain 45 at each side thereof (see Figure 4), and provided with a plurality of transverse bars 46 connecting the chains. The bars 46 may be of angle iron or may be tubular in shape. The elevator is provided with a sheet metal or wooden floor 41, along which the ice cakes |5 slide as they are conveyed up the incline by the bars 46. Suitable sprockets 48 are provided for the conveyor chains 45 at the upper and lower ends of the incline. An adjustment 49 is provided for the bearings of the chain sprockets at the lower end of the elevator for enabling slack in the chains to be eliminated. Suitable guide grooves of wood or metal may be provided on the upper and under sides of the incline surface 41 to guide the movement of the chains 45 as is conventional in the conveyor art.
An ice crusher 55, of any known construction, is supported above the frame 26 on the upright structural members 56 and 34. The crusher preferably has an open hopper 51 on its upper side to which the ice is directed, and into which it moves, by gravity, after reaching the top 3| of the inclined elevator 32. The crusher supporting members 34 and 56 may be suitably braced by cross members 58 to provide a rigid supporting structure. The crusher 55 (the details of which are not a part of this invention) may be of conventional construction having a plurality of picks angularly secured to a rotating drum (not shown). A geared electric motor 59 (see Figure 3) is secured to the frame members 34 and connected by a chain or belt drive 60 to the drive sprocket 6| of the crusher shaft 62 for rotating the latter. Another chain or belt drive 63 is provided between a second sprocket 64 on the crusher shaft 62 and a sprocket 65 secured to the conveyor shaft 33. The conveyor chains 45 engage sprockets secured to the pivot shaft 33 and are driven by the rotation of said shaft. Thus the motor 59 is operatively connected to simultaneously drive the crusher 55 and to operate the elevator 32.
The outlet of the ice crusher 55 is provided with a hopper 66 having aside spout 61. A horizontal rod 68 or the like is provided below and adjacent to the outlet 61 and securely fastened to the frame uprights 34 and 56. As shown in Figures 1 and 4, a removable telescoping, metal chute 69 is supported at its upper end to the horizontal hanger B8, and its lower end is supported by resting on or projecting into the hatch |2 of the refrigerator car ice bunker. By shortening or extending the length of the chute 69, it is possible to reach the various hatches |2 of the cars If] and H, or to reach the hatches of cars (not shown) that may be located on one or more tracks, removed from the platform l4.
The ice elevator and crusher may be provided with an electric motor 15 for propelling the same along the track 2|. The motor 15 is shown connected by chain drive to a sprocket 16 on jack shaft 11, the latter being journaled in bearings secured to the frame uprights 34. A suitable clutch l8 operated by' a hand lever 79 (see Figure 2) is provided to mechanically connect the sprocket 16 to the shaft 11 for driving the latter. The shaft 11 is also provided with one or more sprockets 80, suitably secured or keyed thereto for driving the rail engaging wheels 21 through chains or belts 8| extending between the sprockets 80 and 82 carried by the wheels 21.
Suitable control switches, e. g., push-button control switches 83, and a terminal box 84 are secured to the frame 26 (see Figure 3) to permit centralized control of the electric motors 39, 59, and 15. Also, suitable outlet sockets may be provided at intervals along the platform I4, and a flexible connector cable (not shown) used between one of such sockets and the terminal box 84 to furnish electrical power for operation of the machine, and to propel it along the icing platform, as its position with respect to standing cars requires. Any suitable overhead trolley system or other means for supply of current to the mobile machine may be used in place of the described connector cable as will be readily apparent to one skilled in the art.
The foot or forward end 4| of the inclined elevator 32 is provided with a removable ramp or apron 85 extending between the elevator and the surface of the platform M. The apron 85 may be of metal or wood and is provided at the center with a slot or opening 86 in its leading edge to permit conveyor lugs 20 to pass through the apron. Suitable hooks or hinges are used to secure the upper edge of the apron to the lower end 4| of the elevator.
When using the preferred form of the abovedescribed ice elevator and crusher, the refrigerator car or train of cars to be iced is positioned or spotted on a track parallel and adjacent the elevated platform l4. Ice in the form of cakes or blocks is supplied to the platform |4 either from the adjacent ice house IE or from a distant plant. Large ice blocks may be cut into smaller units either before or after reaching the platform. Preferably ice blocks weighing about,
300 pounds each are received on the platform and conveyed to positions therealong convenient to the elevating and crushing apparatus where they are cut into units of 50 to 100 pounds each prior to being directed onto the elevator 4|. During movement along the platform, the ice blocks slide on the longitudinal runners II which melt or out grooves in the under surface-of each block, such grooves serving effectively to guide the blocks along the platform.
The ice elevator and crusher may be moved along the platform I4 manually or by the described electric motor drive, to a location conveniently adjacent the hatches I2 of ice bunkers to be filled. It will be noted that the elevator and crusher device is so constructed that when the lower end 4| of the elevator is raised, the device has ample underside clearance to straddle ice on the platform so that ice for other delivery points along the platform may pass beneath one machine, or an elevating and crushing machine may be moved along the platform without interfering with ice that is being distributed by a conveyor or is positioned at any point in or along the path of the moving machine.
When the apparatus has been located conveniently adjacent a car to be iced, the telescoping chute B9 is positioned with its upper end supported on the hanger B8 beneath delivery spout 61 of the ice crusher. The lower end of the chute 69 is then placed for discharge into one of the hatches l2 of an ice bunker. The lower end 4| of the ice elevator 32 is next lowered from the position shown in Figure 2, to the position indicated in Figures 1 and 3 by operation of the geared motor 39 and the cable drums 36 connected thereto. The apron 85 is secured to the lower end 4| of the elevator, preferably by hinge connection thereto, and inclined downwardly to contact the surface of the platform l4 at a small angle. An ice block, propelled along the platform manually, or by the conveyor 20, arrlves at the apron 85, and is upwardly directed thereby into 'a position to be received on the elevating conveyor 4|. In case the platform is not provided with a longitudinal ice conveyor, the ice blocks may be manually distributed along the platform and similarly pushed up the apron 85 onto the elevator 4|.
The elevator and crusher, driven by the geared motor 59, are now in operation, and as ice reaches the lower end 4| of the elevator, a cross bar 46 of the elevator engages a block of ice and positively moves it up the inclined surface 41. At the top of the elevator, the ice falls into the hopper 51 of the power-driven ice crusher 55. In the latter, the ice is broken into small pieces of desired size and discharged by gravity into the hopper 66 beneath the crusher. The crusher, as previously stated, may be of known construction and preferably is of a type that is provided with adjust able crushing elements so that crushed ice of desired size range can be produced. The crushed ice collecting in the hopper 66, falls from the hopper spout 61 into the chute 69 and it slides to the ice bunker hatch I2. The spout 61 may, if desired, be provided with a gate valve to control the rate of delivery of crushed ice into the ice chute. A motor operated crushed ice slinger or blower (not shown) maybe substituted for the ice chute 69. In such case, crushed ice from the hopper 66 slides into such a slinger which forces the crushed ice through a flexible hose for thetop icing of commodities in the adjacent vehicle requiring direct refrigeration.
After an ice bunker has been filled with crushed ice, to the desired degree, the elevator and crusher apparatus may be moved in either direction, along the platform to the other end of the car, or to any other of the cars that is required to be iced. When the apparatus is moved along the platform, the removable ramp 85 should be removed or swung up and onto the end 4| of the elevator, and the telescoping chute 68 removed from the hanger 68. If there is no ice on the platform to be passed, the elevator need not be raised to the position shown in Figure 2; but if there are blocks of ice standing on the platform or being moved therealong, to other icing points, then the lower end 4| of the elevator should be raised to the position shown in Figure 2, in which position the apparatus straddles and clears ice in its movement along the platform.
It will be observed that by the use of the above described equipment, the icing of refrigerator cars may be rapidly and efficiently accomplished. Thus, a train of refrigerator cars may be completely iced without the necessity of spotting each car at a definite position for individual icing. By simultaneously using several of the described portable ice elevator and crusher devices, all operating on the same platform, long trains may be iced in a very short time, and with a minimum of shifting or spotting. The equipment permits the ice to reach the bunkers immediately after crushing, and thereby losses due to melting are minimized.
Although the apparatus; shown and described is illustrated as operated'by electric motors, other sources of power, such as an internal combustion engine, may beused instead. Also, various obvious changes in the size, shape, proportion and minor details of construction may be resorted to without sacrificing any of the adv-antages of, or departing'from the herein disclosed invention.
