`
`PORTABLE LIGHTING UNIT
`
`3,272,609
`
`BACKGROUND OF THE INVENTION
`There are numerous instances requiring a relatively
`compact,lightweight, quiet mobile lighting unit capable
`of providing high intensity illumination in the order of
`1~3 million candle powers, for an extended period and
`which is operable independently of stationary or even
`portable power generators.
`Typifying such instances are various night time activ-
`ities, such as building or road construction, security
`checks of warehouses as well as field repair of equip-
`ment and a variety of operations common to mining
`activities where cumbersomegenerators and lights are
`usually hauled to the operating sight in question.
`In still other instances, drug enforcement officials
`have urgent need for silent, portable lights in border
`patrol operations to assist in apprehending smugglers
`and illegal entrants. A similar need exits for emergency
`service personnel, such as paramedics and firemen, who
`frequently are required to perform in remoteor difficult
`to reach areas whereartificial lighting is either unavail-
`able or inadequate.
`While there are numerous known prior art develop-
`ments for mobile lighting equipment, such are normally
`energized by noisy gasoline or diesel powered genera-
`tors, frequently in conjunction with long heavy power
`cables extending between the generator and lights. In
`many such previously developed units, tall elevatable
`masts are employed to mount one or more flood lights
`which, however, makes directional adjustment of the
`elevated lights difficult and cumbersome.
`‘In certain other instances battery powered flood
`lights have been resorted to, but these have been of
`limited lighting capacity and operational duration.
`Still other developments have been directed to porta-
`ble light masts adapted to be detachably mounted on
`motor vehicles, such as fire or light pick-up truck and
`which frequently are powered by heavy and noisy
`motor generators carried by the vehicle.
`Despite such prior developments, therestill exists a
`real and urgent need and demandfora relatively simple,
`mobile emergency lighting unit which is self-powered
`and can be carried by or towed behind a motor vehicle
`and yetis lightweight enough to be manually pulled and
`maneuvered by one or two men over practically any
`terrain while at the same time providing a quiet, high
`intensity and powerful light source that may be quickly
`and efficiently directed, as desired.
`
`BRIEF SUMMARY OF THE INVENTION
`
`This invention is directed to an improved mobile,
`relatively quiet or passive emergency lighting apparatus
`which meets andsatisfies the aforementioned needs and
`obviates the shortcomings of the prior art.
`In brief this invention comprises a lightweight vehi-
`cle frame supported. by multiple ground engaging
`wheels, and which is steerable, remote control or by
`manipulation of a pulling tongue, for example. A heavy
`duty battery is supported on the frame in balanced
`alignment with two axially aligned wheels on opposite
`sides of the frame whereby to promote balance and ease
`of handling the vehicle. A circuit panel is electrically
`coupled to the battery and provides selective switch
`controlled connection with power cables leading to
`twin banks of high intensity lamps adjustably mounted
`atop parallel spaced light bars which in turn are joined

`to the upper ends of four vertically adjustable, tele-
`scopic masts fixed to the vehicle frame. At least one and
`preferably more portable flood lights, also powered
`over the control panel, are carried by mountings at
`opposite ends of the light bars. Such flood lights are
`removeable from their mountings to perform as hand
`held spotlights or alternatively are mountable in porta-
`ble support stands located remotely of the vehicle. The
`several flood lights are individually tiltable and rotat-
`able in their mounts. Similarly the light bars are tiltable
`about their connections with the masts. Manually oper-
`ated switches are providedto selectrically control ener-
`gization ofthe lampsandlights as desired. All the lamps
`and lights are readily accessible to the user throughout
`the range of their adjustment positions.
`It is a primary object of this invention to provide an
`improved and simplified portable, generally noise free
`lighting unit carried by a lightweight vehicle.
`Still another object of this invention is to provide a
`lighting unit as aforesaid which is adaptedto betrailed
`by a motor vehicle and/or manually maneuvered to a
`selected area of use.
`Still another object of this invention is to provide an
`improved and simplified lightweight, portable lighting
`unit carried by a wheel mounted vehicle which sup-
`ports a plurality of high intensity incandescent lights,
`some of whichare removeable from the vehicle and
`capable of operating as mobile spotlights.
`A further and important object of this invention is to
`provide an improved and simplified portable lighting
`unit capable of providing a source of high intensity light
`in the order of two to three million candle powers
`which may be adjusted and directed to desired areas of
`illumination.
`An additional important object of this inventionis to
`provide an improved, simplified, portable lighting unit
`carried by a lightweight wheel mounted vehicle capable
`of being manually moved and manipulated and which
`comprises a plurality of high intensity lamps illuminated
`by a battery source carried by the vehicle.
`Having thus described this invention, the above and
`further objects, features and advantages thereof will be
`recognized from the following detailed description ofa
`preferred embodimentthereof,illustrated in the accom-
`panying drawings, and representing the best mode pres-
`ently contemplated for enabling those of skill in the art

`Projecting upwardly from the frame member 40 and
`adjacent opposite ends thereof, are two parallel dis-
`posed telescopic mast 26, 26¢ preferably made of round
`or square tubular material having an outside diameter of
`23”, conforming with the frame members 40-43.
`In a similar manner, two telescopic masts 27 and 27a
`are fixed at their bottom ends to their associated side
`frame member41 so that the several masts are in mutual
`parallelism. As noted in particular from FIGS. 5 and 8
`masts 26 and 27 are coplanar as are masts 26a and 27a.
`Light metal rectangular tubular cross bar members 53,
`53 extend between the masts members 26, 262, and 27,
`27a, respectively, to provide lateral support andrigidity
`to the maststructures. Each of the masts is receptive of
`one or more smaller diameter extension sections, as will
`appear later, whereby the masts may be extended verti-
`cally to selected elevations.
`It further will be noted that the mast pair 26¢ and 27a
`are somewhatlonger than the masts 26, 27, although all
`masts may be equal length, if desired.
`In the particular embodimentillustrated in FIGS. 5-7
`each of the masts 26-27¢ has a thumb wheel locking
`bolt 55 threadingly engageable with a cooperating nut
`56 located near the upper end thereof for locking an
`inner telescopic section (not shown in these figures) in a
`desired vertical adjusted position. In this respect, the
`nut 56 associated with each thumb operated adjustment
`bolt is welded to the exterior ofits respective mast tube
`over a opening throughthe side walls thereof so thatthe
`inner end of the adjustment bolt 55 may engage a radi-
`ally inwardly disposed tubular extension section.
`In addition, each of the masts 26-27a has at least one
`opening 57 for reception of a locking pin 58 connected
`to the mast by a chain orlike articulatable fasting means
`§9 (see FIG. 5). Such pins and openings maybe utilized
`for quick telescopic adjustment of the inner mast sec-
`tions to raise each mast to a prescribed predetermined
`elevation depending on thelocation of the locking pins:
`and holes with the thumb bolts serving to provide re-
`finement of the adjusted position as required.
`Extending forwardly of the battery carrier made up
`of the frame members 44-47 as previously described,is
`the aforementioned metal floor plate 52 welded to the
`side rails 40, 41 and end frame member 43. Mounted
`atop floor member 52 and adjacent the junction of the
`side rails 40, 41 with the end rail 43, are a pair of mount-
`ing blocks 62, 62 that are welded to the floor plate.
`These blocks are provided with two threaded openings
`63 receptive of cap screwsor the like for fastening the
`control console 37 in position just forwardly of cross
`bar 53, as shown in FIG.4.
`A tubular axle support 64 is mounted transversely
`beneath the side rails 40, 41 of the main frame andfixed
`in place by gussets 65 welded to the frame members 40,
`41 as shown in FIG.5 and 29. The tubular axle support
`64 receives spindle shafts 66 at its opposite ends which
`extend outwardly of the frame members 40, 41. The
`spindle shafts are pressed into the tubular member 64
`and appropriately fixed in place by welding or the like
`to support thetwo ground engaging wheels 22 on oppo-
`site sides of the main frameas illustrated in FIGS. 3 and
`4.
`
`With reference of FIGS. 1-4 of the drawings, it will
`be recognized that the main frame described herein-
`above is supported at its forward end bythe third front
`wheel 23 which in conjunction with rear wheels 22
`effects a tripod or three point support for the vehicle.
`To that end, an angulated neck member 70is fixed at
`
`6
`ss
`one end to the end frame member 43 to extend for-
`wardly of the main frame and provide an over support
`for the third wheel 23. The outer end of the neck mem-
`ber 70, remotely of the main frame, has a bearing assem-
`bly 71 bolted thereto for reception of a vertical stub axle
`72 defining a vertical pivot axis for wheel 23. Such axis
`is aligned in coplanar relationship with the central lon-
`gitudinal axis of the vehicle’s main frame. The lower
`end of the stub axle 72 is fixed to an upper cross arm 73
`of a wheel supporting yoke, indicated at 74. It will be
`recognized from FIG.3 in particular that yoke 74 is an
`inverted U-shape having depending arm 75, 75 through
`which a horizontally disposed axle 76extends so that
`wheel 23 is mounted between the arms 75 of the yoke.
`The upper cross arm 73 of the yokeis fixed to the stub
`axle 72 so that the yoke 74 and wheel 23 are free to
`pivot about the vertical axis defined by stub axle 72.
`To facilitate turning movement of the wheel 23 and
`its support yoke 74, tow bar 24 comprising a manually
`engageable handle portion 80atits outer endis attached
`to the yoke 74 by a U-shaped towing yoke 81 whichis
`pivotally joined to the two arms 75 of the wheel sup-
`porting yoke by bolts 82. In this manner lateral move-
`ments of the tow. bar produce turning movements of
`wheel 23 and the application of appropriate pulling
`force on the tow bar applies corresponding force to the
`vehicle via the front wheel supporting yoke 74. Thus
`manual steering manipulation and propulsion of the
`vehicle may take place. If desired, the tow bar may be
`coupled to a tow truckorthelike for transporting unit
`20 long distances. For clandestine operations the tow
`bar may be eliminated and the wheel 23 equipped with
`a remotely controlled steering motor powered by a
`separate battery power source.
`It will be recognized from FIG. 1 thatin addition to
`handle 80 at the outer end of the tow bar 24, a brake
`handle 85 extends from one side of the tow bar adjacent
`handle 80. This brake handle supports a brake lever 86
`adapted to actuate a sheathed wire cable 87 (see FIG.3)
`leading to.a caliper brake assembly 88 mounted on the
`inside of the wheel supporting yoke 74 and adapted to
`cooperate with a brake disc 89 attached to the wheel
`axle 76 for rotation therewith. The brake assembly 88
`and operator 86, typified by the familiar bicycle or
`motorcycle caliper brake assemblies, operates to brake
`the vehicle front wheel 23 in response to tensioning of
`the cable 87 between the operating handle therefor and
`the brake assembly to engage brake pads with opposite
`faces of the brake disc 89 in a known manner.
`It will be recalled from previous description that the
`several mounting masts 26, 26a, 27 and 27a carry across
`their upper ends a pair of parallel spaced light bars 28
`and 29. Inasmuchas the twolight bars are identical, a
`description of one will suffice for both and to that end
`reference is now made to FIGS. 10-15 wherein the
`features of light bar 28 are set forth.
`As shown in best in FIG. 14 of the drawings, light bar
`28 comprises a shallow rectangular cover 95 adapted to
`close over the upper side of an elongated rectangular
`open top box frame 96. Cover 95 as best detailed in
`FIGS.10 and 11 comprises an elongated, planar rectan-
`gular profiled top wall 97 which forms the top of the
`assembled light bar and which is bordered by down-
`wardly turned elongated parallel side walls 98, 98 inter-
`connected at their opposite ends by relatively short
`parallel end walls 99, 99. The top wall 97 is distin-
`guished by a pair ofrelatively large circular openings
`100 adjacent the end walls 99 thereof and four interme-
