Definitions

  • An object of the present invention is to provide an amphibious craft more compact, structurally stronger and having a higher watertight integrity than the type of craft shown in US. Pat. No. 2,546,523 and US. Pat. No. 3,418,961 which because of unitized all-welded construction which is, in the pontoon area, reinforced with vertical bulkheads, and transversely positioned I- beams will resist moments of force which cause other vehicles of the type shown in the above patents to twist, buckle or be subjected to torsional stresses which will open welds on the pontoon causing flooding and loss of buoyancy of the craft.
  • a further object of the present invention is the provision of a pontoon type endless track vehicle which will support and carry into swamps, marshes and other inaccessible areas heavy loads such as draglines, hydraulic tree cutters, equipment moving A-frames for transporting loads up to sixty tons without fear of losing the load due to a loss of buoyancy or buckling of the buoyant pontoon and the inability of the endless track drive to move the vehicle and its work load over tree stumps, marshes, water or soft land in which other vehicles become bogged down and cannot operate.
  • heavy loads such as draglines, hydraulic tree cutters, equipment moving A-frames for transporting loads up to sixty tons without fear of losing the load due to a loss of buoyancy or buckling of the buoyant pontoon and the inability of the endless track drive to move the vehicle and its work load over tree stumps, marshes, water or soft land in which other vehicles become bogged down and cannot operate.
  • a still further object of the present invention is a vehicle having pontoon buoyant supports about which move endless drive chains having cleats connected between a pair of chains which move with a minimum amount of friction requiring less driving horsepower and which has plastic blocks of a low coefficient of friction which not only act as friction reducers but as support members between the cleats and pontoon resulting in little or nobuckling of the traction cleats between their drive chain attachments.
  • a still further object of the present invention is the provision of a pontoon craft of the type described which is provided on its top andbottom of each pontoon with low coefficient of friction plastic material which cooperates with plastic blocks to reduce wear and horsepower necessary to move the vehicle and its work load into and out of inaccessible places whether it be solid land, marsh and/r water or a combination of any of the foregoing.
  • An object of the present invention is the provision of a pontoon vehicle having endless tracks running over the top and bottom of the pontoon wherein the pontoon at its leading end has an undercut nose which will permit the vehicle and its work load to rock and absorb various shocks incident to terrain changes or tree stumps or foreign objects which would otherwise impose sudden shock moments on the pontoons resulting in breaking of weldments in the pontoon causing a loss of buoyancy necessary to support such work loads as drag lines, hydraulic tree cutters, etc.
  • FIG. 1 is a front perspective view of one form of amphibious pontoon endless track vehicle constructed in accordance with the present invention.
  • FIG. 2 is a rear perspective view of the vehicle of FIG. 1.
  • FIG. 3 is a top plan view of the pontoon and joining structure of the vehicle of FIGS. 1 and 2.
  • FIG. 4 is a side elevational .view of the pontoon structure of the present invention.
  • FIG. 5 is a perspective view with parts broken away showing the reinforcing and buoyancy structure of a pontoon constructed in accordance with the present invention.
  • FIG. 6 is a fragmentary front elevational view of one of the pontoons and driving cleats showing the support blocks bearing against the plastic filled channels.
  • FIG. 7 is a front elevational view of the endless track support shaft showing the free floating bearing support of the drive sprocket shafts.
  • FIG. 8 is a diagramatic hydraulic schematic of one of the pontoon endless track drive systems.
  • 10 designates an amphibious craft constructed in accordance with the present invention having pontoons 11 and 12 maintained in parallelism by I-beams 13, 14, and 15 welded to the pontoons.
  • shafts 16 having drive sprockets 17 thereon, best seen in FIG. 7.
  • Each shaft is journaled in bearings 18 secured to angles 19 welded to the pontoons 1'1 and 12 proximate the upper portion thereof.
  • support blocks 24 secured to the webs of the channels so that they will bear against either the top or bottom of the pontoon or a channel 25 filled with a low coefficient of friction plastic such as an epoxy, teflon or nylon to act as a frictionless wear surface over which the support blocks 24 which may be of polypropylene to reduce both wear and friction.
  • a low coefficient of friction plastic such as an epoxy, teflon or nylon to act as a frictionless wear surface over which the support blocks 24 which may be of polypropylene to reduce both wear and friction.
  • the endless track is driven from the rear shaft, FIG. 7, which has a drive sprocket keyed thereto and which is itself driven by a chain 26 driven from a hydraulic motor 27, one drive motor for each'pontoon.
  • the pontoon 12 has a top 12A, a bottom 12B, and side walls 12C and 12D.
  • the interior of the pontoon is divided into a plurality of water tight buoyancy chambers by bulkheads 12E, 12F, and 12G which are welded to the sides and bottom plates.
  • the bulkheads add structural strength to the pontoon as well as a buoyancy chamber wall.
  • I- beams 12H running transversely of the major axis of the pontoon and welded to the bottom plate 128.
  • the combination of bulkheads and the I-beams together with the longitudinal channels 25 on the top and bottom of each pontoon provide a rugged structure resistant to bending, buckling, twisting or cracking of plate weldments, a unique feature which permits the vehicle of the present invention to operate prolonged periods of time without damage to its structure.
  • the longitudinal channels 25 form both runways for the endless chains 20, 21 to which the track cleats 23 are secured and the support blocks 24 over the middle area of the cleat act as a frictionless load bearing surface to reduce both wear and horsepower requirements necessary to drive the vehicle.
  • the pontoon structure described cooperates with the unitizcd welded beam construction of beams 13, 14, and 15 to provide a rugged buoyant structure which can support in water, marsh or land loads of up to 60 tons which permits the mounting on the top of the pontoon structure of drag lines, tree cutters and other heavy duty construction equipment.
  • the under cut nose portion of the front of the pontoon as best seen in FIG. 4 is attained by bulkhead 12E being of lesser vertical height.
  • the major load bearing portion of the pontoon being from bulkhead 12F to the rear.
  • the rocker-like construction afforded by the undercut leading nose permits the vehicle to climb over obstacles such as tree stumps and ditches, levies and banks, and upon returning to a level running surface to rock back to a stable running attitude.
  • FIGS. 1 and 2 The embodiment shown in FIGS. 1 and 2 is equipped to transport personnel and has a SO-ton lift in the form of a U-frame 30 pivoted to the main frame and raised and lowered by hydraulic cylinders 31.
