Abstract
An ambulatory fire fighting apparatus comprising at its front end a device for lifting the overburden and comminuting and exposing the nonflammable soil which passes unded a rotary drum which pulverizes the soil and discharges the pellets of dirt through a guide chute, the chute being associated with a fan which has branches for directing of air entraining the pellets and pressurizing the drum.
Claims19
An aggregate throwing device for use in fire fighting movable over supporting terrain comprising a housing having a pair of sidewalls and an arcuate intervening wall and having an open bottom and discharge opening through said arcuate wall,
- a rotary brush-type drum mounted within the housing for rotation about a generally horizontal axis and projecting through said open bottom, and operative to dig into and comminute the soil therebeneath and discharge the same through the discharge opening and,
- said drum comprising a plurality of flexible digital members adapted to spring back attendant to digging into the soil and to spring forward upon withdrawal from the soil for flinging the soil through said discharge opening,
- and said members having spoon-shaped ends for cupping the soil therein while digging the soil.
Fire fighting apparatus having means for removing overburden including weeds and soil and the like from an an area adjacent to burning terrain to expose nonflammable soil therebeneath,
- means for comminuting said soil into discrete particles and said apparatus having means including a guide chute for directing particles onto the burning areas,
- and said comminuting means comprising a disk plow at the leading end of the apparatus for cutting the overburden, and
- a share plow behind the disk plow for folding the overburden laterally for exposing the nonflammable soil.
A field traversing fire fighting apparatus movable in a predetermined direction toward a fire, said apparatus having means for removing overburden including weeds and sod and the like from an area adjacent to burning terrain to expose nonflammable soil therebeneath,
- means including several different independent components spaced longitudinally from each other in the direction of travel of said apparatus in transferring relation to each other for serially comminuting said soil into discrete particles, and said apparatus having means including a guide chute for directing said particles in a trajectory onto the burning area,
- one of said components comprising a drum comprising a pair of laterally spaced peripherally sharpened disks and a plurality of radial earth digging and cutting tines confined between said pair of disks and operative to scarf into particles between said disks the soil and comminute it and propell said particles through said chute, said drum having a soil-engaging front side and means for rotating the drum with its soil engaging side sweeping upwardly on its front side, and means for adjusting said chute into alignment with the trajectory of said particles from the drum and a discharge chute positioned in front of said front side of the drum for receiving said particles directly therefrom.
Fire fighting apparatus having means for removing overburden including weeds and sod and the like from an area adjacent to burning terrain to expose nonflammable soil therebeneath,
- means for comminuting said soil into discrete particles, and said apparatus having means including a guide chute for directing particles onto the burning areas,
- and said apparatus having a drum comprising a pair of laterally spaced peripherally sharpened disks and a plurality of radial earth digging and cutting tines confined between said pair of disks and operative to scarf the soil and propell it through said chute,
- and said tines each comprising a spoon-like outer end adapted to scoop the soil and to centrifugally cast the soil cupped thereby through said chute.
A unit for fighting forest fires and the like comprising ground traversing apparatus movable in a direction toward the fire,
- means for stripping the terrain in an area adjacent to the fire to expose noninflammable soil,
- means for comminuting the exposed soil, and
- means for directing such noninflammable comminuted soil onto the burning terrain, and including
- a rotary drum positioned behind said directing means and having soil scraping means for reducing the soil into slingable pellets, and
- said drum having means for confining the scraped soil to prevent lateral dispersement of the pellets and maintaining sufficient volume thereof for maximizing discharge of the pellets through said directing means, said drum being positioned to advance into the soil thereahead in said direction of movement of the apparatus and rotating in a direction to lift the soil into said directing means.
A unit for fighting forest fires and the like comprising ground traversing apparatus,
- means for stripping the terrain in an area adjacent to the fire to expose noninflammable soil,
- means for comminuting the exposed soil, and
- means for directing such noninflammable soil onto the burning terrain, and including
- a rotary drum having soil scraping means for reducing the soil into slingable pellets, and
- said drum having means for confining the scraped soil to prevent lateral dispersement of the pellets and maintaining sufficient volume thereof for maximizing discharge of the pellets through said directing means,
- and
- said drum having a housing comprising a pair of side plates and an interconnecting peripheral wall, and
- said peripheral wall having a vertically movable trailing portion comprising a lower end with a ground-engaging shoe adapted to ride over the terrain.
An aggregate throwing device for use in fire fighting movable in a predetermined direction over supporting terrain comprising a housing having a pair of sidewalls and an arcuate intervening wall and having an open bottom and a discharge opening through said arcuate wall,
- a rotary brush-type drum mounted within the housing and having bottom and front sides, for rotation about a generally horizontal axis in a direction from the bottom upwardly ahead of its front side and projecting through said open bottom and operative to dig into and comminute the soil therebeneath and discharge the same through the discharge opening, said housing having a ground-soil engaging lip ahead of said drum for guiding the soil from said drum over said lip.
An aggregate throwing device for use in fire fighting movable over supporting terrain comprising a housing having a pair of sidewalls and an arcuate intervening wall and having an open bottom and a discharge opening through said arcuate wall,
- a rotary brush-type drum mounted within the housing for rotation about a generally horizontal axis and projecting through said open bottom, and operative to dig into and comminute the soil therebeneath and discharge the same through the discharge opening and,
- in combination with a discharge duct connected to said housing for directing the comminuted soil onto a fire, and
- means for augmenting the throw of the soil by the drum comprising a blower for delivering a stream of air operative to entrain the soil as it discharges from said duct, and
- said drum housing having an air inlet and said blower having a branch line extending in proximity to said air inlet and providing a zone of pressurized air directed at said inlet.
