Definitions
- This invention relates to multi-purpose vehicles. Specifically, it relates to an improved light weight, highly efficient muiti-purpose vehicle particularly adapted for underground digging and hauling applications.
- multi-purpose vehicles typically employ an X-shaped, or box-shaped frame with a conventional cab on the front, and a cabin or bed attached along the length of the frame, such as the amphibious vehicle designed by Fletcher et al, U.S. Patent No. 2,923,268.
- the conventional multi-purpose vehicle has forward steering wheels and rear drive wheels.
- a number of conventional vehicles may be harnessed together in series. This requires a long pulling space to accommodate the aligned vehicles connected in series.
- These harnessed vehicles are also difficult to turn and cause the rear vehicles to run in the tracks left by the forward vehicles; often times resulting in poor traction of the trailing vehicles.
- the aligned vehicles when harnessed, generally move in a longitudinal direction. Non-pivoting wheels of conventional vehicles do not allow significant sideward movement, which makes it necessary to uncouple and recouple the vehicles where it is necessary to move the load laterally.
- articulated vehicles such as those described in Hutt, U.S. Patent No. 4,249,629, and Domenighetti, U.S. Patent NO. 3,914,065 have been utilized.
- a series of carts pulled by a main drive vehicle may be employed, such as the Fire Fighting and Rescue Apparatus described by P.F. Cummins, U.S. Patent No. 3,169,581.
- these articulated vehicles enable a series of harnessed vehicles to turn in a shorter radius, they do not solve the problem of the rear aligned vehicle's poorer traction as it travels in the same tracks left by the forward vehicles.
- SLH self loading hauler
- SLH vehicles tend to have a length slightly greater than a light hauling design vehicle, with a length greater than the combined width and height of the vehicle.
- the excessive length is tolerable in a majority of underground operations since the drifts (tunnels) are long in comparison and have a narrow width and low height.
- the excessive length of the SLH contributes to counter-balancing the oversized payloads.
- the narrow width complicates turning and side slope stability. This requires judicious design of the basic frame structure and the location of the components within it. Low height is not only desirable from
- BSTITUTE SHEET an operating stand-point, but is also necessary in order to improve the stability of the SLH.
- Applicant's invention eliminates the pulling traction problems, while providing an efficient ergonomically designed SLH vehicle with a centrally located operator station. It has independent wheei drive and suspension which can move laterally, if desired, for greater mobility. Applicant's U-shaped frame multi-purpose vehicle can also nest with one another to enable a number of them to be aligned in a lesser space than conventional vehicles for pulling heavy objects. They also may be interconnected front to back in a formation which insures that the wheels of the trailing vehicles do not follow in the same tracks as the forward vehicles.
- British Patent 1 ,203,338 incorporates a conveyor assembly running the length of the bed. It therefore is of a box-like shape rather than a U-shaped vehicle which can nest or interconnect for pulling and pushing articles.
- British Patent No. 1 ,059,656 uses a flexible articulated frame shown in Figure 5, which lifts and bends during lifting to scoop earth.
- British Patent No. 1 ,059,656 also incorporates a conveyor system into its bed for materials handling and movement.
- British Patent No. 1.059,656 materials handling vehicle is not capable of acting as a personnel carrier. Muotka et al, U.S. Patent No. 3,520,432 utilizes a box frame which requires a Blade 4 to rearwardly transport materials to the rear of the bed.
- U.S. Patent No. 4,505,638 is another example of a box frame, utilizing a horizontal pair of tracks along which its bucket travels. This loading movement of the bucket action differs from applicant's as described below. Cited for general interest is Cohen, U.S. Patent No. 4,065,825.
- SUBSTITUTE SHEET Summary of the Invention comprises a multi-purpose vehicle having a U- shaped frame.
- the U-shaped frame has opposing sides with front ends connected to a front piece, and rear ends defining an open end.
- a plurality of wheels are independently suspended and rotatably attached with wheel mounts to the opposing sides.
- Various types of conventional pivot means may be attached to the wheel mounts to allow each pivot to independently turn in a desired direction for independent steering.
- each wheel also has an independent drive motor associated with it to rotate said wheel in a forward or rearward direction, giving the vehicle wide directional steering latitude.
- a power source such as a conventional combustion engine, operates the pivot means and independent drive means.
- Control means mounted to the frame are associated with the drive means and pivot means to selectively activate them to align and drive each wheel and the vehicle at the desired speed and direction.
- the drive motors are preset to run at their optimal efficiency points.
- a variable speed transmission such as that described in assignee's co- pending application, Serial No. 742,997, entitled “Variable Speed Transmission”, is then included in the drive train to provide the desired speed and torque to each wheel.
- a digging system component is mounted within the U-shaped frame.
- the digging system component has a U-shaped open top bucket load chamber tiltably attached to the frame. The opposing sides of the bucket load chamber are attached to a bed.
- the rear chamber side ends are connected by a back piece to form an open topped U-shaped carrier having a frontal opening leading into an interior load carrying space of the chamber.
- the chamber sides and back are sloped to aid in emptying loads from the bucket load chamber, when tilted.
- a bucket loader is attached to the front sides of the bucket load chamber with means to transfer the contents of the bucket loader into the bucket load chamber.
- the bucket loader has a bottom and opposing sides defining an open topped scoop with open ends The forward open end of the bucket loader bottom is sharpened to dig and scoop earth, ore, and the like.
- the sides define a narrowing opening from front to back to concentrate materials scooped up by the front end of the bucket loader for discharge through its open rear end.
- Oscillation means may be included to provide low frequency oscillations to the bucket loader to assist the bucket loader in digging and scooping material.
- dumping means such as dump cylinders with one end attached to the U-frame and the other end attached to the bottom of the bucket load chamber selectively raise and tilt the bucket load chamber to the dump position.
- the dumping means selectively lift and vertically tilt the bottom of the bucket ioad chamber to unload said chamber through the open end of the bucket loader.
- the dumping means then lower the bucket load chamber for receipt of materials in the second mode.
- the bucket functions as an open tailgate when in the first mode.
- the bucket is then selectively lowered so that additional material may be carried in the bucket after the bucket load chamber is filled for hauling in the second mode.
- a cab is mounted to position the operator in view of the gully cleaning operations.
- the cab is sized to accommodate the operator, and includes at least one door opening for the operator to enter and exit the cab.
- Wheel mounts are then attached to the sides of the drive frame.
- Conventional pivot means are associated with the wheel mounts to pivot and turn each wheel mount up to 25 degrees in a desired direction.
- a plurality of wheels are then independently suspended and rotatably attached to the wheel mounts via conventional mounts.
- Drive means such as an internal combustion engine utilizing hydrostatic wheel drive, are mounted on top and towards the rear of the U-frame beneath the cab.
- the engine is operably associated with the wheels via a conventional transmission drive train to rotate the wheels forward or backward.
- Control means-- i.e. a control panel mounted within the cab-are operably associated with the transmission to control the output from the drive means, and the speed of the wheels.
- the control panel also controls the pivot means to selectively align each wheel in the desired direction.
- An auxiliary power source such as a hydraulic system, is also controlled by the control panel to selectively operate the tilting means, and bucket loader.
- the type of transfer means required to empty the bucket loader into the bucket load chamber is dependent upon the type of material typically
- the preferred transfer means utilizes a bucket loader which is vertically lifted rearward and simultaneously tiited to empty the contents of the bucket into the bucket ioad chamber.
- the guides are slideably mounted to run along arched tracks running along both front and top exterior sides of the bucket load chamber.
- the tracks are arched and aligned to travel upward and rearward.
- a drive piston has one end attached above the track and the other end attached to the bucket loader to force the bucket loader rearward when activated.
- the bucket loader is forced rearward, it is simultaneously lifted in an arc, and the bottom of the bucket loader tilted as the guides travel along the tracks to transport and empty the contents of the bucket loader through its open rear end into the load chamber.
- the bucket loader is lowered and also filled to carry additional material.
- the operator then drives the loaded SLH vehicle to the dump site.
- the dumping means are activated by the control panel to raise and incline the bucket load chamber and bucket loader to empty their contents through the open front of the bucket loader.
- transfer means for handling loose material has the bottom of the bucket loader hingedly attached to the front of the frame. After loading, the bucket loader is then pivoted and tilted with a drive piston to rearwardly transport and empty the contents of the bucket loader into the bucket load chamber. The loaded SLH vehicle is then driven to the dump site and emptied in the manner described above.
- the transfer means preferably includes at least one drag arm to assist in emptying the bucket loader by dragging the large objects from the bucket loader into the bucket load chamber. These drag arms avoid the problems encountered with the first lift transfer means discussed above which would drop rocks, causing damage to the bed, or allow them to bounce out, endangering the operator.
- a wide drag arm with fingers runs the width of the bucket load chamber opening.
- the drag arm is pivotally associated with a pair of slides having first and second ends.
- the slides run along longitudinal parallel top grooves in the exterior sides of the bucket load chamber.

- the drag arm is pivotally mounted to the slides near the bend of the L to pivot upward and downward as the rockers are activated. in operation, the drag arm pivots up and down and is extended to cover the length of the bucket loader. To pull material, the arms and fingers are extended in the most forward position, and pivoted downward for the fingers to hook on and grab large boulders, or rocks. The drag arm is then forced rearward via the loading hydraulic pistons discussed below, dragging the boulders or rocks from the bucket loader into the bucket load chamber.
- the arms are selectively adjusted with controls in the control panel which the operator varies to position the drag arms.
- the bucket loader may also be simultaneously partially raised and angled to provide gravity assistance in emptying the bucket loader.
- the gully cleaning system vehicle may be operated by remote control.
- the SLH vehicle is adapted with revolving electronic viewing means, such as a remote control operated camera, capable of receiving and transmitting picture signals. Picture signals are then transmitted to the remote receiver viewing screen via a transmitter.
- a remote vehicle control system in communication with the control panel is then included to enable an operator to transmit signals to position and operate the vehicle from a distance.
- the SLH vehicle includes separate independent drive motors and steering means for each wheel. Either electrical or internal combustion engines drive motors may be utilized, depending upon fuel supply, availability, and cost.
- the drive motors are preset to run at their optimal efficiency levels.
- a variable speed transmission such as that described in assignee's co-pending variable speed transmission application above, is then included in each drive train to provide the desired speed and torque outputs to operate the drive wheels.

- the front and rear mounts 94,96 have three interconnecting hinges to provide added stability and prevent twisting.
- the front of the drive frame 98 has both ends angled to accommodate the digging system frame 68 and enable the articulated joint 66B to bend more; thus providing a shorter turning radius.
- a cab 106 to mid-position an operator for centralized control of the gully cleaning operations.
- the cab 106 is sized to accommodate the operator, and has a door opening 108 for the operator to enter and exit the cab 106.
- a remote control camera 107 to transmit picture signals for remote operation of the vehicle is mounted behind the cab 106.
- Similar pivoting wheel mounts 109 as discussed above shown in Figure 17 are attached to the sides of the drive frame 98. Wheels 110 are then independently suspended and rotatably attached to the wheel mounts 109.
- An internal combustion engine power source 111 utilizing hydrostatic wheel drive 114 separately drives the wheels via a wheel motor 115.
- Control means such as a control panel 112 in the cab is operably associated with the transmission, engine 111 , and wheel pivot means to control and drive the vehicle via a wheel end drive unit 114.
- SUBSTITUTE SHEET 116 sending signals to a remote control panel 113 may be included where underground gases are a threat to the operator.
- An hydraulic system (not shown), is associated with the hydraulic pistons and also controlled by the control panel 112 to selectively operate the bucket loader 86 and bucket ioad chamber 76.
- Figure 9 is a top view of the vehicle 10 showing the turning radius.
- Figure 10 is a front view of the bucket loader 44 showing how the sides 46 are structured to narrow its rear opening to concentrate and rearwardly force materials to aid in loading the bucket load chamber 32.
- Figure 11 illustrates another preferred embodiment of an articulated self loading hauler system vehicle 10 utilizing drag arms 52 similar to those described above and shown in Figure 4.
- a bucket oscillation device (not shown) vibrates the bucket loader 44 to further assist in loading the bucket loader 44.
- Figure 12 is a side view of the Figure 1 articulated self loading hauler system vehicle showing the manner in which the drag arms 44 are moved forward and backward to assist in loading.
- Figure 13 is a side view of the Figure 11 articulated self loading hauler system vehicle showing the manner in which the load bucket chamber 32 is emptied.
- Figure 14 illustrates another preferred embodiment of an articulated self loading hauler system vehicle 10 utilizing a hinged bucket loader 44 similar to that shown in Figure 4.
- the bucket loader 44 is hingedly attached to the sides 34 of the bucket toad chamber 32.
- the bucket loader 44 is emptied by pivoting and tilting the bucket loader 44 rearward as shown in Figure 15.
- the loaded bucket load chamber 32 is then dumped utilizing dumping cylinders 92, as shown in Figure 16.
- the length of the self loading hauler system vehicle 10 is longer than its combined width and height. This enables the vehicle 10 to worked in confined working spaces in underground mines. Included in Figures 7, 8, 9, 10, 12,13, 15, and 16 are preferred dimensions of the various vehicle configurations.
