Definitions

  • An attachment for removing wet snow and slush adapted to be detachably coupled to a raisable and lowerable snow plow is disclosed.
  • the novel attachment comprises an oblong frame which defines two ends and a front and rear when attached to a snow plow.
  • a flexible strip is fixed to the length of the frame at the front thereof for moving over the surface so as to remove wet snow and slush.
  • Members are incorporated in the frame between the front and rear thereof on which the lower portions of the snow plow rest. Wheels are mounted on the frame and located behind the rear thereof so as to support the attachment for rolling movement over the surface.
  • Detachable coupling of the attachment to the snow plow is achieved via coupling means.
  • the employment of snow plows for the removal of wet snow and slush is simplified and made more etficient, all without danger to the street pavement.
  • the invention relates to an attachment for removing wet snow and slush from surfaces, for detachable coupling to a raisable and lowerable snow plow.
  • a device of this kind which is easily moved about, and quickly coupled to, and uncoupled from, a snow plow, is greatly needed in the colder regions of the world, where the fallen snow in winter must be expeditiously removed.
  • the attachment of the invention because it is supported on wheels, is easily removed from storage and brought to the spot where it can be coupled to the snow plow. When no longer needed, the attachment is just as easily uncoupled and stored.
  • the invention answers a particularly pressing need, because it simplifies and speeds the efficient employment of snow plows for the removal of wet snow and slush, without danger to the street pavement.
  • FIG. 1 is a view in cross section of a first embodiment of the invention
  • FIG. 2 is a top view of a part of the first embodiment
  • FIG. 3 is a view in cross section of a second embodiment of the invention.
  • FIG. 4 is a top view of a part of the second embodiment.
  • FIG. 5 is a partial view in the direction of the arrow V in FIG. 3.
  • the snow plow incorporates a plow proper 1, an arrangement 2, shown In dot-dash line, for raising and lowering the plow, rib-s United States Patent O "ice 3 on the rear face of the plow, the usual beam 4 along the lower edge of the plow, a reinforcing member 5 in the lower part of the snow plow, and the customary runner 6, which slides on the street pavement when the lower edges of the plow 1 and the beam 4 are badly worn.
  • the attachment shown in FIGS. 1 and 2 includes an oblong connecting frame 7.
  • the latter incorporates a dash 8, having an L-shaped section and extending the width of the plow 1.
  • a connecting strip 10, U-shaped in cross section, and a clearance strip 11, for removing the wet snow and slush, made of rubber or of some other suitable flexible material, are fastened to the dash 8 by means of bolts 9.
  • the connecting strip 10 and the clearance strip 11 are of the same length as the dash 8.
  • a bed plate 12 is welded to each end section of the dash 8. To each end section, along the lower edge thereof is also welded a connecting plate 13, which projects downwards and rearwards.
  • each plate 13 To each plate 13 are welded an arm 14, U-shaped in section and projecting rearwards and slightly upwards, and a support plate 15, which also extends rearwards and upwards.
  • a horizontal plate 16 is welded to the underside of the plate 15 and the outer face of the inner wall of the arm 14.
  • pocket means are provided to detachably receive at least a part of the lower portions of the plow.
  • An arm 18 is mounted, by means of a pivot 17, to pivot about a vertical axis.
  • Two wheels 19 are mounted on the rear of each arm 18 to revolve about a horizontal axis.
  • a connecting rod 20 is connected to the inner wall of the arm 14, approximately at the middle thereof, to pivot about an axis 20' extending horizontally and parallel to the main axis of the frame 7.
  • a lever 21 which is detachably supported by a pin 22 fixed to one of the ribs 3, to which a stop 23 is also fastened.
  • the lever 21 is pivoted clockwise (as seen in FIG. 1) beyond a dead-center position, the handgrip of the lever 21 comes to bear on the stop 23, as illustrated in FIG. 1.
  • the combination of connecting rod 20 and lever 21 thus provides a detachable connection between the attachment and the snow plow.
  • the parts 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 are also present at the other end of the dash 8 and connecting strip 10, but their arrangement is mirror inverted.
  • the attachment is independently movable, enabling it to be easily removed from its store place.
  • the tractor or other vehicle on which the snow plow is mounted is then so maneuvered that by merely lowering the snow plow (by means of the arrangement .2) the parts 4, 3, and 6 of the plow generally defining lower portions thereof are brought to the position illustrated in FIG. 1, whereby the underside of the snow plow slides along the upper side of the arms 14, and the parts 4 and 6 finally come to rest against the respective parts 12 and 16 of the attachment.
  • the coupling arrangement 20 and 21 There remains only to bring the coupling arrangement 20 and 21 into its operative position.
  • the snow plow is supported on the pavement through the frame of the attachment and the wheels 19.
  • the flexible removal strip 11 exerts virtually constant pressure on the pavement which is to be removed of slush.
  • the slush slides up the strip 11 and thence sideways along the plow 1. It is assumed, in this connection, that the snow plow is canted, as is conventional, to the direction of vehicle movement with the wheels 19, however, by virtue of the pivotal mounting of the arms 18, being oriented in the direction of forward progress.
  • the attachment is easily removed and put to one side.
  • certain of the support surfaces are so arranged that they are contiguous with the lowest surfaces of the snow plow. Since these surfaces of the snow plow are frequently dented when removing snow, it has proved desirable to remove these surfaces to a position where they cannot be so damaged. It has also been observed, particularly to ensure good functioning of the arrangement for detachably coupling the attachment to the snow plow, that it is desirable to provide a trim and precise positioning of the attachment with respect to the snow plow along the direction of the width thereof. To this end, a vertical pin projecting into a bore would 'be an obvious solution. But it would be irksome to have to position the snow plow with respect to the attachment so that the pin and the bore were aligned, before lowering the plow.
  • the parts 1, 2, 3, 4 and 5 of the snow plow, and the parts 6, 7, 8, 9, 10, 11, 12 and 13 of the attachment are essentially the same as in the previous embodiment.
  • the rear end of each arm is provided with a pivot support 24, having an approximately horizontal pivot axis, in which a pivot pin, of a connecting member 25, free to rotate but not displaceable, is mounted.
  • the member 25 carries a further connecting member 27.
  • a forked arm 29 is connected to the member 27 to pivot about 28.
  • the rear of the arm 29 supports a wheel 19 for rotation.
  • the lower end of a screw spindle 33 is mounted to pivot about an axle 32 which is parallel to 28 and 30 and located in the upper forked end 26a of the joint bolt.
  • the spindle 33 passes through a bore in the block 31, which bore has a diameter greater than that of the spindle.
  • On each side of the block the spindle carries a respective nut 34 and 35.
  • a positioning pin 36 is welded at its base to each arm 14a.
  • the upper end of each pin terminates in a cone 36a incorporating an included angle of between approximately 60 and 90 and an outside base diameter of approximately 12 cm. or more.
  • a cylinder 38 have a surface 38a matching that of the cone 36a, is securely mounted on each end of the plow 1 by means of a pair of ribs 37.
  • Each device includes an elastically flexible, curved connecting rod 39, the lower end of which is mounted to pivot about a pin 40, which extends in the direction of movement of the snow plow and is secured to the arm 14a by means of lugs 14b.
  • the upper end of the rod 39 is pivotally'connected to a lever 41, which has a forked portion that is detachably supported by a pin 42 welded to the cylinder 38. By pivoting the lever 41 clockwise (as seen in FIG.
