Definitions

  • ABSTRACT An engine driven vibratory plate compactor fully selfcontained and easily maneuverable by the operator.
  • a vibratory plate assembly and an engine assembly are separable units interconnected by shock absorbing means isolating the superstructure of the compactor from vibration effects at the plate, with the maneuvering handle being doubly isolated substantially to reduce operator fatigue.
  • An exciter compartment on the vibratory plate is sealed to exclude dirt and the plate on its upper surface is inherently self-cleaning.
  • Engine components overlie the vibratory plate in a close coupled compact arrangement and include a multifunctional roll-bar type frame.
  • An adjustable throttle control enables variable compaction rates to suit vary* ing work requirements.
  • the instant invention provides a compact, low slung device designed for trouble free operation over an extended life span. It has a relatively small number of parts and is otherwise equipped to minimize wear effects.
  • the engine and associated parts are isolated from the vibratory plate by a unique form of shock damping connector, with a maneuvering handle being doubly isolated. Means to exclude dirt are provided, such means being designed, however, to avoid dirt entrapment, allowing the upper floor surface of the vibratory plate to be inherently self-cleaning.
  • a heavy duty type engine features a throttle control whereby the operator can select a rate of compaction to suit the kind of material being worked and the work requirements.
  • the engine seats on an engine base plate from which rises a tubular frame.
  • a fuel tank and an air cleaner mount above the engine in a novel manner adding to the compact nature of the device and placing the cleaner above areas of heavy dust cooncentration.
  • a water supply source and water distribution system are made an integral part of the compactor in order that the surface being worked may be wet immediately in advance of the vibratory plate.
  • An object of the invention is to provide a generally new compactor offering operational and reliability advantages as well as freeing the operator from much of the fatigue and handling difficulties normally associated with use of devices of this class.
  • Another object of the invention is to introduce a concept of protection of operating parts of the compactor tending to exclude dirt and producing a self-cleaning function.
  • a further object of the invention is to enable the device to be controlled to vary the rate of compaction.
  • Still another object of the invention is to construct the compactor with separate engine and vibratory plate assemblies so interconnected as to form a unitary device but substantially to isolate the engine component from vibratory effects of the plate.
  • a still further object of the invention is to provide a superstructure for compactor devices advantageously locating and supporting parts such as the fuel tank and air cleaner.
  • FIG. 1 is a view in perspective of a compactor in accordance with the first illustrated form of the invention
  • FIG. 2 is a view in side elevation of the compactor of FIG. 1;
  • FIG. 3 is a view in cross section, taken substantially along the irregular line 3-3 of FIG. 2;
  • FIG. 4 is an exploded perspective view of the vibratory and base plate assemblies, operating parts being omitted for clarity;
  • FIG. 5 is a detail view in cross section showing a connector mounting the engine base plate to the vibratory base plate;
  • FIG. 6 is a fragmentary view in perspective, similar to FIG. 1, showing a modified form of compactor device which includes a water distribution sytem.
  • a compactor in accordance with the embodiment illustrated in FIGS. I to 5 comprises work contacting means in the form of a vibratory base plate 10.
  • the vibratory base is a formed steel member or is otherwise constructed to be a part of rigid, heavy structural characteristics. It is generally rectangular in configuration. Opposite ends are bent upward in a staged manner to define at each end a first inclined surface 1 1 and a second, more sharply inclined surface 12. What may be considered leading and trailing endsof the vibratory plate accordingly are formed to ride easily over thework. Improved climbing and pre-breakup of lump material results, as well as easier maneuvering.
  • the vibratory plate is constructed as a flat planar portion 13 supporting the plate upon the work surface.
  • Side margins of the plate are turned up to a lesser extent than the ends thereof and define relatively shallow lips 14.
  • Sides of the plate, above what may be considered the upwardly facing floor surface thereof, are substantially open.
  • the member 15 Resting on the upwardly facing floor surface of the vibratory plate is a generally rectangular tube-like member 15, the ends of which abut the turned up ends 11 and 12 of the plate. By a welding or like process, the tube-like member 15 is secured to the plate 10 and becomes in effect an integral part thereof, the ends of the tube being sealed by the joining process.
  • the member 15 is a housing and defines interiorly thereof a closed exciter compartment. In opposite side walls of the housing are opposing openings 16. Secured to the upper surface of the compartment housing 15 is a series of brackets 17. Outer free ends of the brackets 17 project laterally of and downwardly of the housing 15, the extremities of such ends disposing in an inclined relation to the flat planar portion 13 of the vibratory plate.
  • the vibratory plate and housing 15 thereon comprise part of a vibratory base plate assembly further including exciter means contained within housing 15.
  • An end cap 18 is adapted to bolt to a side of housing 15 in a position of closure with respect to one of the openings 16.
  • a cylindrical boss 19 on the cap 18 projects into the opening 16, having a relatively close fit therein.
  • a bearing assembly 21 is mounted within to be confined by the boss 19.
  • a through central opening 22 in the cap 18 has an oil seal 23 therein.
  • end cap 24 mounted in to close the other opening 16. End cap 24 is constructed similarly to cap 18 except for omission of the through opening 22.
  • a boss 25 thereon it mounts a bearing assembly 26.
  • a shaft 27 is transversely disposed within housing 15 and has one end portion mounted in bearing assembly 26. Near its opposite end, shaft 27 is formed with a reduced diameter portion 28 mounted in bearing assembly 21. Beyond its engagement with bearing assembly 21, the shaft 27 projects through cap opening 22 and is further reduced in diameter to define a shaft extension portion 29. Within housing 15, and intermediate its ends, the shaft 27 is eccentrically weighted. In the illustrated instance, the eccentric weighting is accomplished by an integrally formed laterally projecting portion 31 of the shaft but might otherwise be accomplished, as by the mounting of separate individual weights.
  • the shaft 27 is adapted to be rotated and when rotated delivers relatively powerful vibratory impulses to the plate 10, through the housing 15 thereon. Rotating means is illustrated in the form of a pulley 32 fixed to shaft extension 29.
  • a V-belt 33 engages in pulley 42 and acts as a motion transmitting means, as will more clearly appear hereinafter.
  • the housing 15 In the housing 15 is contained lubricant in the form of an oil bath 34.
  • a fill port 35 for the oil is located in an upper wall of the housing 15.
  • the housing 15 defines a closed compartment, as has been seen. End caps 18 and 24 engage within the housing in a substantially sealed manner, and bearing assembly 21 is sealed by means 23.
  • the exciter compartment, as defined by the housing interior accordingly is sealed against loss of lubricant.
  • the sealing off of the housing interior is also effective in a reverse sense in that dirt and dust particles from outside the housing are denied access to the exciter compartment.
  • the base plate 36 Disposing in an overlying relation to the vibratory base plate 10, and to the housing 15 thereon, is an engine base plate 36.
  • the base plate 36 is formed from heavy sheet steel or the like and comprises a flat rectangular planar portion 37 which is in a superposed spaced relation to the housing 15 and substantially aligned therewith. Side margins of the plate 36 are bent downward from the plane of portion 37 and depend therefrom as wing-like portions 38 and 39. These dispose at an angle inclined from the plane of portion 37 and achieve an approximately parallel relation to the bent extremities of brackets 17. Spaced locations on the wing-like portions 38 and 39 are interconnected to the brackets 17 by connector devices 41.
  • the several devices 41 position the engine base plate in an elevated spaced relation to the vibratory base assembly and serve a dual function in interconnecting the assemblies which mount thereon and in effectively damping vibrations so that vibratory effects resulting from rotation of the shaft 27 are substantially confined within the vibratory base assembly.
  • the connector devices 41 are alike. Each comprises a cylindrical body 42 made of a solid rubber or rubber-like material to have a limited resilience. Opposite ends of the body 42 are recessed and in such recesses are respective nuts or nut-like members 43 and 44. Members 43 and 44 are aligned with one another and are suitably secured within their respective recesses, as by being integrally united with the body 42 in a molding or like process. Each connector 41, therefore, comprises a resilient body 42 having in tegrated attachment means at its opposite ends in the form of nut-like members 43 and 44.
  • the bent over extremities of the brackets 17 are apertured and a headed screw fastener 45 is passed therethrough from the underside and turned into threaded engagement with a member 43.
  • a like headed fastener 46 passes through an aperture at each of the described spaced locations on the wing-like portions 38 and 39 and is turned into threaded engagement with a nut-like member 44.
  • the connectors 41 accordingly are effectively clamped between the engine base plate 36 and the housing 15 forming a part of the vibratory base assembly.
  • Engine base plate 36 is relatively firmly secured thereby in the superposed, spaced position illustrated, the resilient connector device 41 permitting, however, limited relative movement between the vibratory base assembly and the engine base plate.
  • a relative approaching motion of the parts is damped by the connectors 41, however, with the rate of damping gradually increasing by reason of the angular disposition of the connectors.
  • the connectors 41 dispose in similar fashion and are subjected to shear and compression forces in a relative approaching motion of the base plates.
  • FIG. 47 Another set of resilient connector elements 47, which are or may be identical to the elements 41, is used to mount handle members 48 to opposite sides of the engine base plate 36.
  • Wing-like portion 39 of the engine base plate provides spaced apertured locations to which respective connectors 47 mount, fasteners 49 being inserted from the underside of portion 39 to en gage in a nut-like member in one end of each connector 47.
  • a handle member 48 bridges the opposite ends of the connectors 47 and is apertured for passage of a threaded fastener 51 therethrough to engage in a nutlike member in such opposite end of each connector.
  • a like handle member 48 is mounted in similar fashion, by way of connectors 47 to wing-like portion 38.
  • the handle members 48 are formed, as by a casting or like operation, to provide a recess 52 on its side facing base plate 36.
  • a U-shaped control handle 53 Connected to the members 48, a U-shaped control handle 53 has a generally inverted attitude with its free ends in embracing relation to the engine base plate. Each such free end is received in a respective recess 52 of a handle member 48, between its resilient mounting connectors 47 and suitably anchored thereto.
  • the handle 53 rises upwardly from and rearwardly of the base plate and its closed end provides a grip portion for the hands of the operator.
  • the handle 53 serves as a maneuvering and guiding means for the compactor. It is twice removed from the source of vibration, by reason of the separate sets of connectors 41 and 47 and accordingly is doubly isolated with respect to the vibratory base assembly to minimize shock transmissions to the operator.
  • An engine 54 is mounted on to project vertically upward from the base plate 36.
  • the mounting means includes an engine base 55 and a bracket 56 bolted into the base portion 55 from the underside of plate 36.
  • the engine 54 is a gasoline burning engine of multiple horsepower. It is of a commercially available type and is comprised of components which it will be unnecessary here to consider in detail.
  • a power generating section 57 positively rotates a shaft 58 connected by a centrifugal clutch 59 to a driving pulley 61. The latter overlies the previously mentioned pulley 32 on shaft 27 and has a common connection therewith with the V-belt 33.
  • An opening 62 in the engine base plate 36 allows passage of the V-belt to assume an interconnecting relation between the engine assembly and the vibratory base assembly.
  • a guard member 63 is mounted on the upper surface of plate 36 in a partly surrounding, protective relation to the pulley 61 and the V-belt depending therefrom.
  • a carburetor 64 is mounted to engine section 57 and draws air through a hose connection 65 and liquid fuel through a tube 66, the latter incorporating a filter 67.
  • a throttle means including a pivotal lever 68 controls the rate of burning of the combustible mixture and thereby the speed of operation of the engine. Air reaches hose 65 from the atmosphere by way of an air cleaner 69. Tube 66 draws fuel from a fuel storage tank 71.
  • the air cleaner and the fuel tank are uniquely mounted in an overhead relation to the engine by means including a formed sheet metal plate 72.
  • the plate 72 has a generally rectangular configuration with turned down ends 73 and 74. Adjacent end 73, the plate has a shelf-like portion 70 to the upper surface of which air cleaner 69 is suitably bolted.
  • a manifold 75 mounted beneath shelf-like portion 70 connects the air cleaner 69 to the hose 65.
  • the plate 72 has a curved or upwardly recessed portion 76 terminating in down turned end 74.
  • the configuration of portion 76 is such as substantially to conform to the shape of fuel tank 71, the latter nesting within the curved portion 76 on the underside of plate 7 2.
  • a series of straps 77 is in a mutually surrounding relation to curved plate portion 76 and to the tank 71 and fix the tank in the nested position illustrated.
  • the plate 72 has apertures 78 providing for passage of the straps 77 therethrough and the straps have joints 79 by which they may be tightened and loosened.
  • An engine guard 81 rises from the engine base plate 36 in a protective relation to engine components while permitting comparatively easy access thereto.
  • the guard 81 serves also as a means to support the mounting plate 72. It is comprised of bent tubular members 82 and 83 of inverted generally U-shape having their ends anchored substantially at the corners of the flat planar portion 37 of plate 36 to dispose thereby in parallel relation and to rise perpendicular to opposite side edges of this plate.
  • tubular members 82 and 83 are transversely interconnected by a pair of longitudinally spaced similarly configured parallel members 84 and 85 and these in turn have their uppermost central portions interconnected by a transverse tubular portion 86 which extends fore and aft of the base plates.
  • the latter is bent upward intermediate its ends at a point substantially to coincide with the center of gravity of the compactor unit to provide a point of attachment for a crane, hook or the like.
  • the mounting plate 72 has its turned down ends 73 and 74 welded or otherwise secured to tubular guard portions 84 and 85.
  • the engine is started using a pull rope means 87 forming a part of a rewind starter 88 with backup rope sheave.
  • a pull rope means 87 forming a part of a rewind starter 88 with backup rope sheave.
  • the latter is adapted for remote adjustment, a Bowden wire cable 89 being attached at one end thereto and extending upward to the mounting plate 72 where it passes through an aperture in the shelf-like portion 70.
  • the cable 89 attaches to a lever 91 pivotally mounted to an isolator stud 92 secured to the mounting bracket.
  • An arm 93 of the lever 91 extends laterally in an overlying relation to the bracket 72 and is adapted for convenient manipulation by an operator to effect extending and retracting motions of the cable whereby correspondingly to vary the setting of throttle lever 68.
  • the control arm 93 is settable to an idle position at which time engine 54 operates at minimum speed and is ineffective to actuate centrifugal clutch 59 to rotate pulley wheel 61. Operation of the engine at this time accordingly is without effect on the vibratory base assembly, shaft 27 remaining inactive.
  • engine speed increases and centrifugal clutch 59 automatically engages with the result that a driving connection is established from the engine to shaft 27.
  • the vibratory shaft accordingly rotates in its exciter compartment delivering vibratory impulses to the com pactor base plate 10 at a rate bearing a direct relation to the speed of operation of the engine.
  • the setting of the throttle control arm accordingly determines the compaction force.
  • the throttle provides a high compaction force. Retraction of the throttle provides a lesser compaction force until an idle position is reached at which time compaction is interrupted.
  • the multi force control lever accordingly permits the unit to be operated at a speed best suited for the material being worked and the work requirements.
  • the compactor acts upon compressible materials and as the material beneath the machine becomes firm the machine walks or moves of its own momentum in response to the generation and application of the vibratory impulses.
  • the operator, grasping handle 53 can guide the unit and otherwise maneuver it in operation to achieve the desired ends in the most expeditious manner.
  • a shorting button 94 is mounted on the engine and is depressible to stop engine operation.
  • the vibratory means 31 is totally enclosed within the housing 15. Dirt and dust particles are excluded therefrom and from the bearings 21 and 26 by the positive seal afforded by end caps 18 and 24 and associated parts. Further, the wing-like portions 38 and 39 of the engine base project downwardly in a protective relation to side margins of the vibratory housing 15. The housing, and in particular the pulley 32 and V-belt 33, are shielded from impact by stones and heavy particles. Dirt clods, which might tend to accumulate around the exciter compartment housing tend to be excluded by the wing-like portions. According to a feature of this aspect of the invention, however, the engine base is not in a fully enclosing relation to the exciter compartment housing.
  • the vibratory base plate is in effect self-cleaning in that its vibratory action is utilized to dislodge dirt particles and expel them outwardly over the marginal lips 14 or over the upturned ends 12.
  • the margins of the vibratory base plate and marginal edges of the engine base plate cooperate in defining an open passage 95 which extends on all four sides of the defined assembly.
  • the connector devices 41 act as shock insulators between the vibratory base assembly and the engine assembly. In effectively isolating and confining the vibratory impulses to the vibratory base assembly the imposition of stresses in the engine assembly is avoided prolonging the useful life of engine components.
  • Handle means 53 is twice removed, as noted, from the source of vibration, enabling the operator to guide and maneuver the unit without the discomfort and fatigue normally associated with operation of vibrating tools.
  • the handle 53 has been described as being suitably anchored to the members 48.
  • the handle may be welded to such members in a fixed position or, as in the illustrated instance, be pivotally connected thereto for reversibility. As seen in FIG.

  • the guard 81 has a roll-bar configuration completely protecting all working parts and it will be noted in this connection that uppermost portion 86 of the guard achieves an elevated relation to the air cleaner 69.
  • Mounting plate 72 closes the space above the engine, offering protection to the engine components and direct contacting protection to the fuel tank 71 which it mounts.
  • the air cleaner 69 thrusts upwardly of plate 72 and so is positioned high in the compactor unit away from levels of heavy dust concentration.
  • the compactor unit carries a reservoir of water and is equipped to distribute water on the work surface ahead of the advancing unit.
  • a compactor unit is constructed like the unit of the first considered embodiment, comprising a vibratory base plate 97, an engine base plate 98, an engine 99, guard 100 and other associated parts, all constructed and operating in substantially the same manner as corresponding parts of the first described embodiment.

  • the connection of hose 107 to the tank 104 may include an appropriate fitting 108 incor' porating a valve (not shown) whereby gravity flow of water from the tank to the trough may be initiated and discontinued as required.
  • water flows from tank 104 to pipe 103 and is distributed thereby into trough 102. The water flows over the open edge of trough 102 and trickles down the end face 101 of the compactor plate to the work surface.
  • the addition of water is advantageous in the compacting of certain surfaces and under some conditions, as for example in the compacting and finishing of asphalt to avoid adhesion.
  • the second illustrated form of the invention utilizes connector device corresponding to devices 41 and 47 of the first considered embodiment.
  • operation of the compactor generates shear and compression forces, as the vibratory base and engine assemblies move relatively to one another and as the compactor is guided over the work surface.
  • the devices 41 and 47 are uniquely constructed and disposed in angular relation to optimally absorb such forces without deterioration over extended periods of usage.
  • Their solid yet resilient construction, and the absence of vibration transmitting connectors as a part thereof, insures a smooth, trouble-free performance and contributes to the minimizing of fatigue effects.
