Definitions

  • the present invention generally relates to a runway sweeper, that is to a machine for sweeping snow or dirt off a road, particularly an airport runway.
  • the machine usually includes blowing means for blowing matter loosened by the brush but which has somehow not been brushed aside the road.
  • the invention relates to a new suspension means for mounting the brush assembly on the frame and a new supporting means for supporting the assembly over the ground.
  • Such machines are already in existence bait have a major disadvantage in that the brush assembly is rigid with the supporting frame so that whenever the carriage, on which the engine and the brush assembly are mounted, is jolted as a result of the machine yhitting an obstacle, the complete machine, including the brush assembly, is affected. Since the obstacle is hit by the wheels of the carriage, located forwardly and rearwardly of the bmsh, the latter responds unnecessarily thereto by rising so that a portion of the road is left uncleaned. Should the road to be swept be somewhat rough, the same upward movement -or rattle lof the brush 'assembly is repeated so that the road surface is not properly cleaned.
  • Another important object of the invention lies in the provision of a support for holding the brush at a predetermined relationship with the road surface whereby as the brush wears off, it is Ipossible to lower it from its support a distance corresponding to the worn olf portion.
  • Still another object of the invention is to provide such a support ⁇ as aforesaid with which it will be possible to completelywithdraw the brush from actual Contact with the road surface, whenever desired.
  • the invention relating to a nunway sweeper having a brush, a rigid supporting member secured to the brush and extending longitudinally thereof to form a brush assembly and a frame, the novelty residing in the provision of a suspension for mounting said assembly to the frame, cornprising: an upper arm articulated at one end to the frame and mounted at the other end on the rigid member to pivot about an axis parallel to said member; a lower arm or structure articulated at one end to the frame, below the articulation of the upper arm to the frame, and mounted at the other end on the rigid member below the pivot connection of the upper arm, to the rigid member to pivot about an axis parallel to said member, and means to apply a lateral thrust on each side of the lower arm, intermediate the ends thereof to cause swinging of the lower arm and brush assembly about an axis extending through the articulations of the arms to the frame.
  • the invention is also perfected by the addition of means for supporting the brush assembly over the road to be swept and including a support on each side of the suspension, each support comprising: a wheel carrier including 3,284,831 Patented Nov. 15, 1966 an upstanding support bracket; a pair of connecting bars; pivot joints mounting one end of each bar to the bracket and the other end of each bar to the rigid member; the joints forming the four corners of a deformable parallelogram, and an extensible and retractable power ram pivotally connected at one end to one of said bars, intermediate the ends thereof, and at the other end to the rigid member, whereby extension of the extensible ram causes rising and lowering of the brush assembly.
  • the extensible and retractable'power ram is, by itself, novel and comprises a' cylinder, a fluid pressure operated piston slidable in the cylinder and a rod xed to the piston and slidable in the cylinder; means in said cylinder limiting the stroke length of said piston and means to displace t-he limiting means axially of the cylinder whereby the stroke position of the piston vin the cylinder may vary while lche stroke length thereof remains constant.
  • the piston is an annular member and the ram is provided with a threaded rod mounted for rotation only in the cylinder so as to extend through the annular piston; a nut threaded over the rod whereby rotation of the rod produces displacement of lche nut relative thereto and to said cylinder; co-operating means on the nut and annular piston to limit the displacement of the piston and rod connected thereto relative to the nut and cylinder.
  • FIG. l is a general perspective view of -a runway sweeper made according to the invention.
  • FIG. 2 is a top view of the runway sweeper of the invention
  • FIG. 3 is a side elevation View of the runway sweeper of the invention.

  • the rigid member 27 is also a drive shaft housing and as such is a hollow cylindrical member and contains two drive shafts 31 and 31 (FIG. 4). ⁇ The said drive shafts 31 and 31' connect to axial shaft 33 of brush 17 (FIG. 4) through any known transmission means hidden from view in FIGS. 1 and 3 by a guard 35.
  • Power for drive shaft 31 is obtained through a differential rotated by a telescoping drive rod means 39 connected to differential 37 and to a power take-off 43 through universal joints 41, 41', the power take-off 43 being from the engine of the engine portion 1. It will be noted that the extensible and contractible drive rod 39 passes between the upper and the lower struts 23, 23'.
  • the suspension of the invention adapted to interconnect the brush assembly 11 and the frame 3 represented in FIG. 4 by transverse struts 23, 23 comprises an upper arm 45 articulated at one end to upper strut 23 and pivoted at the other end to the top of differential 37.
  • the articulation of upper arm 45 to upper strut 23 can be of any known type and it should be understood that by articulation, or articulated joint, is meant a connection between two members whereby one member may be moved, relative to the other member, in any direction and this definition applies to articulation or articulated joint as used in this specification.
  • the said articulation comprises a vertical pin 47 secured to upper strut 23, the lower end of pin 47 and the corresponding end of upper arm 45 being interconnected by any known ball joint 49.
  • upper arm 45 has an eye piece 50 fitting between two upstanding ears 51 of the casing of differential 37, a pin 53 being driven both through ears 51 and eye piece 50 to allow upper arm 45 to swing or pivot about an axis parallel to member 27 which is generally horizontal.

  • the lower structure 55 is formed with two spaced legs 57, each pivotally mounted on and between a pair of ⁇ spaced parallel links 59 by means of a pin 61.
  • Legs 57 form a triangle at the apex of which is secured a transverse bar 63 the outer ends of which are xed to further bars 65 also connected to the lateral faces of legs 57.
  • articulation of structure 55 to the lower transverse strut 23 is through an arrangement similar to articulation 47, 49 of upper arm 45, that is, a vertical pin 47' and a ball joint 49'. Pins 47, 47' are in vert-ical axial alignment.
  • the two articulations (47, 49-47', 49') and the pivot joints (50, 51 53-59, 61) are so located as to effectively form the four corners of a parallelogram.
  • a pair of rams 67 are mounton chassis 25 to apply a thrust at the outer ends of transverse bar 63 of structure 55.
  • a universal joint 69 connects the operating rod of each ram 67 to the outer ends 'of the transverse bar 63.
  • the centers of the universal joints 69 are in rectilinear alignment with the center of joint 49 to avoid any conversion of the steering forces on the structure 55 into forces tending to increase or lessen the load of the broom assembly, or, conversely to prevent any transfer of vertical forces or components of force from the broom assembly to the carriage assembly or viceversa, through the structure 55.
  • brush assembly 11 will be allowed displacement independently of frame 3 represented by transverse struts 23, 23' because of the pivot connections 50, 51, 53 of upper arm 45 and 59, 61 of lower -arm 55 as well as their respective articulations 47, 49, 47', 49'.
  • selective operation of rams 67 will permit swinging of the brush assembly 11 relative to Iframe 3 about a vertical axis which is also the axis of pins 47, 47.

  • a pair of upper connecting bars 77 and lower connecting bars 77 interconnect support brackets 73 and columns 75, two-by-two, by means of pivot joints 79, the pairs of bars 77, 77' being xed respectively above and below the shaft housing 27. It will :also be noted that the said bars are so connected that the pivot joints are located at the four corners of a deformable parallelogram in the manner of the upper and lower arms 45, 55, as previously mentioned.
  • An extensible and retractable power ram 81 is pivotally mounted between columns 75 ⁇ and at the upper end thereof, and between the lower bars 77 through a short link 83 rigidly xed to the said lower bars 77.
  • a triangular ligure is obtained having the two spaced columns 75 as one side, part of the two spaced lower bars 77', up to short links 83, as the second side and power ram 81 as the third side. Because all three apices of the triangle are pivot connections and that power ram 81 is an extensible and retractable member, the said triangle is deformable. Consequently, and with special reference to FIG.
  • the fluid pressure operated ram of FIGS, 7, 8 and 9 has a piston with adjustable stroke position but constant stroke length.
  • Rod 91 is o f course mounted in telescopic manner in cylinder 85.
  • a threaded rod 93 is mounted for rotation only in cylinder 85 and extends through the annular piston. Rotation of threaded 'rod 93 in relation to cylinder 85 may be obtained manually by means of crank 95 with operating knob 97.
  • a nut 99 is threaded over rod 93 whereby rotation of the rod by means of crank 9S produces displacement of nut 99 relative to cylinder 85, if nut 99 is prevented from rotating by -it-s connection to piston 87, as hereinafter described.
  • Cooperating means is provided on the nut 99 and on the annular piston 87 to limit displacement of piston 87 and rod 91 Iconnected thereto relative to cylinder 85.
  • the cooperating means just mentioned preferably comprises a radial shoulder 101 at the upper end of nut 99, the said shoulder being formed with a plurality of arcuate guiding grooves 103 (see FIG. 9) at the periphery thereof.

  • each bolt has a head 107 made to abut the lower face of piston 87 and a small inner flange 108, the latter being in sliding contact with the outer surface of nut 99.
  • the bolts 105 extend through a washer 109 lying on top of piston 87 and is screwed into position by means of a nut 111.
  • the raising and lowering of the broom is Ahydraulically controlled whereas periodic trimming of the brooms lowermost position is achieved by simple manual adjustment of the stroke limits or .position of the piston 87. It will therefore be appreciated that neither the raising and lowering nor the adjustment of the stroke position of the piston rrequire any amount of ihard manual labor.
  • the adjusting screws 93 beco-me automatically Ifriction looked in either the up 'or the down positions of the lifting ram and there is no tendency or disadjustment to loosen out or wander through the effect of the weight of the broom assembly or of vibrations, and to thereby cause the broom to come in closer and possibly damaging contact with the ground.
  • the provision of means to adjust the lowermost position of the broom is necessitated by the gradual wear of the broom itself.
  • FIGS. l and 10 are shown certain constructional features of the blowing assembly 15 which is generally composed of a central blower 115 from the outputs of which are connected two ducts 117, generally rectangular in cross-section, directing the air downwardly toward the road pavement.
  • a nozzle portion 119 at the lower end of the straight vertical portion, sends the air to hit the road at a slight angle to thus force dirt or snow toward the side of the road.

  • rDhe square end of duct 117 is guided against the square end of output 1'27 of blower 115 and held thereagainst by a yoke -129 pivotally secured to both duct 1117 and output 127.
  • the mouth 137 of nozzle 119 has a closing door 131 hinged, Vas at 133.
  • a longitudinally resilient hook 13-5 is provided on either sides of mouth to retain the door 131 in closed or open posit-ion thereof.
  • 17 may be raised when not in use to prevent them from hitting an obstacle on the road.
  • Door 131 may be ⁇ closed if only one duct is required.
  • Both air nozzles 119 are rotatable through 180 by means of hydraulic motors and are always similarly directed perpendicularly to the center line of the wheeled carriage; both nozzles facing either left or right.
  • the two air nozzles are in tandem, each using approximately one half of the volume of air that would be used if a single nozzle of twice the cross-section area was used to cover the full width of the swept path. Yet it is more effective since, given equal escape velocities from the nozzles, the drop in the velocity of the escaping air is the same per unit of length, resulting in higher average air velocity across the width of the swept pat-h.
  • T-he trap doors 131 are closed to completely eliminate the air blowing when none is wanted suoh as when operating in the vicinityo'f buildings, parked aircraft and the like.
