Definitions

  • This invention pertains to powered snow removal equipment, and more specifically, to a motor-powered device wherein a rotating blade member is effective for readily impelling snow considerable distances from the plow.
  • a typical device of this type is shown in United States Patent No. 3,078,603, and as is usually the case, includes a wheeled frame, and a relatively heavy engine.
  • the discharge chute tends to clog and thereby interrupt the plowing activity.
  • an object of this invention to provide a new type of lightweight and inexpensive snow plow, especially suited to use by a homeowner, wherein clogging is substantially eliminated by use of an impeller in the form of a paddle which impels the snow through a plurality of directionally controllable flexible vanes.
  • FIGURE 1 is a top plan view of the plow, with a portion of the handle broken away.
  • FIGURE 2 is a side elevation corresponding to the view shown in FIGURE 1.
  • FIGURE 3 is a perspective view taken from the left rear corner, and with the motor removed.
  • FIGURE 4 is a front view of the plow, wherein the flexibility of the discharge-vanes is shown in dotted lines, and
  • FIGURE 5 is a cross section view of the snow impeller.
  • Our improved snow plow includes a rotor housing 10, which may be formed in metal, linear polyethylene, or any suitable material.
  • Housing has an upstanding backwall portion 11, left and right side portions 12 and 13, respectively, and a bottom portion 14, integrally formed as shown.
  • Bottom portion 14 has an arcuate cross section and forms a continuous surface or moldboard with backwall portion 11 for directing the snow upwardly from between the side portions 12 and 13, and into the discharge-vanes 90, under the influence of the rotating paddle assembly 30.
  • Side portions 12 and 13 are held in fixed spaced relation by skid 15 and U-shaped bracket 20, as shown.
  • Skid 15 is positioned acros the lower portion of housing 10, and is bolted to sides 12 and 13 by means of wheel support plates 16 and 17, which are rigidly attached to skid 15.
  • Small wheels 18 and 19 are rotatably mounted to wheel support plates 16 and 17, respectively, as shown.
  • the upper surafce of skid 15 is positioned so as to provide a smooth continuous surface with bottom portion 14 of housing 10.
  • U-shaped bracket 20 provides additional support for housing 10, being positioned against the outer surfaces of side portions 12 and 13, and backwall portion 11, as
  • Bracket 20 is bolted at its extremities to housing 10 by means of bolts 21, and provides a solid support for paddle 30.
  • This support is best seen in FIGURE 4, wherein a portion of the right end of paddle 30 is broken away and the bearing assembly is shown in cross section.
  • Stud 22 is rigidly attached to plate 23, which is in turn bolted through side portion 12 to bracket 20 by means of bolts 21.
  • a bushing 24 having a flange at its outer end is rotatably positioned on stud 22, and is pressed into the end of shaft 31 of paddle assembly 30 as shown.
  • paddle assembly 30 freely rotates between the side portions 12 and 13 of housing 10.
  • Paddle assembly 30 consists of two paddles 32 and 33 mounted on a shaft 31 by means of a plurality of bolts 34 and -U-shaped re-enforcing brackets 35 and 36 as is most clearly seen in FIGURE 5.
  • a sprocket 50 is rigidly attached at the right end of the assembly as seen in FIG- URES 1 and 4.
  • Paddles 32 and 33 are preferably formed from linear polyethylene, and are somewhat enlarged along the outer end as shown at 37, and 38, respectively.
  • the inner edge of each paddle is formed with a plurality of spaced parallel grooves 40, which engage the complementary spaced parallel ridges 41 formed on the opposite sides of shaft 31 as shown.
  • the outer edges of the paddles often scrape against the sidewalk or other surface on which the plow is used, causing a wearing away of the edges of each paddle.
  • the bolts 34 can be loosened and the paddles can then be moved outwardly until grooves 40 are in alignment with the next set of ridges, thereby lengthening each paddle to compensate for the wearing that has occurred.
  • the bolts 34 are then retightened and the lengthwise grooves and ridges 40 and 41 effectively prevent paddles 32 and 33 from turning with respect to shaft 31, even though bolts 34 pass through relatively long slots 42 in each paddle. It will be observed that this arrangement permit-s several successive adjustments of the bladeas the wearing proceeds inwardly on each paddle.
  • a gasoline engine or motor 45 which includes a recoil starter operated by rope 46 and handle 47, is rigidly attached to bracket 20 by means of motor support brackets 48, 49 and 50 as shown.
  • the motor is of a conventional, horizontal shaft design including a housing 51, a carburetor and governor assembly 52, an integral cover 53 formed over its single cylinder (not shown), a mufller 54, a spark plug 55, a spark plug shorting strap 56, an ignition wire 57, and an output shaft 58.
  • a sprocket 59 is attached to shaft 58, and a driven sprocket 60 attached to shaft 31 is driven by means of chain 62, which extends through openings (not shown) in the backwall portion of housing It We have not found it necessary to provide a clutch on this device, but it should be understood that a clutch could be provided to permit starting the engine without load, rather than providing a direct chain drive as shown.
  • Chain 62 is provided with a guard 63, shaped as shown and bolted to the housing 10 as is best seen in FIGURE 3.
  • Guard 63 is formed with inner flanges 64 and 65 as shown, as added protection against snow getting onto motor 45.
  • no guard is provided for chain 62 within housing 10, since we have found such a guard to be unnecessary during operation.
  • Motor 45 is enclosed by means of two additional housing members '70 and 71.
  • Bottom member 70 is in the form of a shallow basket, which fully encloses the underside of motor 45, and it serves as a skid during operation.
  • the foreward portion of housing member 70 is bolted to housing 10, and the upper rear portion of member 70 is secured to one of the handle assembly bolts 84 on either side of the machine.
  • a gas tank 66 is fastened to the upper rear portion of member 70, and gas line 67 extends through the backwall of member 70 to motor 45.
  • cover member or shroud 71 which has a rear opening (not shown) for gas tank fill tube 68, and a side opening 73 for muflier 54, said opening 73 being re-enforced by forming the perimeter of the opening into an outwardly extending flange.
  • a small opening in the top cavity 74 is provided for pin 75, to permit the operator to push the shorting strap 56 against spark plug 55 without removing cover 71.
  • Pin 75 is attached to a spring member 76, which is in tunn fastened to cover 71, and the operator merely pushes the pin into engagement with strap 56 in order to force it against spark plug 55, whereafter strap 76 restores pin 75 to the position as shown.
  • Handle assembly 80 consists of a forward handle 81, a rear handle 82, a pair of handle assembly brackets 83, and a plurality of handle assembly bolts 84.
  • the forward handle 81 is shaped as shown with its forward ends bent downwardly on either side of the machine (behind guard 63 in FIGURE 2), and terminating to the rear of skid 15 with a forwardly curved portion 85 at each end which wraps around a portion of housing 10.
  • Bolts 86 are used to attach the handle 81 directly to housing 10.
  • Rear handle 82 extends directly rearwardly from brackets 83 as shown.
  • a right-handed operator may grip handle 81 in his left hand, and the handle grip area 87 is positioned with respect to the center of gravity such that plow assumes a proper plowing attitude when lifted by means of handle 81.
  • the right hand could then be used to grip handle 82, to permit swinging the plow back and forth in somewhat the same manner as a conventional snow shovel.
  • the operator may wish to push the plow ahead of himself with both hands on handle 82, and wheels 18 and 19 resting on the surface to be plowed.
  • handle 81 to housing is spaced away from the point of attachment of the U-shaped engine support bracket 20, and since linear polyethylene is used for housing 10, there is a substantial dampening of the engine vibration so as to minimize vibration in handles 81 and 82.
  • the handle also facilitates storage, since the plow can be conveniently hung up on a wall by means of handle 82.
  • side portions 12 and 13 have been formed with a substantially straight portion to facilitate standing the plow against a wall or in some other out-of-the-way place with handle 82 substantially vertical.
  • vanes 90 The discharge of snow from our plow is accomplished by means of a group of highly flexible vanes 90 attached to housing 10.
  • Each vane is shaped as is most clearly seen in FIGURE 2, to include mounting tabs 91 and 92 at either end as shown.
  • Each of the lower tabs 92 is formed with a detent which holds the vane in position when tab 92 is pushed through an elongate slot in housing 10.
  • the short key tab 91 at the upper end of each vane fits loosely into a horizontal slot 93 in vane mount 94.
  • vane mount 94 is moved laterally as shown in dotted lines in FIGURE 4, the top of each vane is correspondingly flexed to one side, while the bottom of the vane is held in a fixed position by elongate lower tab 92.
  • a plurality of channels is provided between the several vanes to deflect the snow as desired.
  • selector plate 95 which has a handle portion 96 at its upper end.
  • Selector plate 95 is slidably mounted to vane mount 94 by means of two pins 97 formed as an integral part of vane mount 94, which extend through vertical slots 98 in selector plate 95 as shown.
  • Nuts 99 hold plate 95 on pins 97, but permit sliding motion with respect thereto.
  • a spring 101 on the lower pin 97 engages the outer extremities of selector plate 95 as shown, and urges plate 95 downwardly on pins 97 as is shown in FIG- URE 3.
  • vanes The positioning of vanes is accomplished by means of a central bracket 102 attached to U-shaped bracket 20, and a horizontal pin 103 rigidly attached to bracket 102, bracket 102 being also attached to backwall portion 11 of housing 10 so as to add rigidity thereto. Pin 103 cooperates with grooves 104 in selector plate as is best seen in FIGURE 3.
  • pin 103 engages a slot 104 in plate 95, and spring 101 prevents plate 95 from moving out of engagement with pin 103, and pin 103 therefore holds the vanes 90 in the selected position.
  • FIGURE 3 we have shown the vanes deflected to the left, and if the operator desires to throw the snow to the right, he merely lifts upwardly on handle 96 to disengage pin 103 from plate 95, and then moves the entire selector plate and vane mount assembly laterally as is shown in dotted lines until pin 103 is in alignment with the desired slot 104, and then releases handle 96. Thereafter, pin 103 holds the selector plate 95 in the desired new position until the operator again makes a change.
  • the operator In operation, the operator normally lifts handle 81 or 82, or both, until the bottom surface of skid 15 is substantially parallel with the surface to be plowed, and it will be noted that the backwall portion 11 of housing 10 is then tipped approximately 20 degrees forwardly of vertical as viewed from the side of the machine.
  • the operator then adjusts vanes 90 to the desired attitude by means of the selector plate, and-assuming the engine has been started-the plow is then pushed into the fallen snow.
  • the paddles 32 and 33 rapidly impel successive quantities of snow backward and upward along the bottom 14 and back 11 walls of housing 10, and the forward attitude of wall 11, combined with the selected displacement of vanes 90, causes the snow to be impelled in the desired direction to some distance away from the plow.
  • the plow works well as compared with contemporary plows because there is a minimum of snow compaction, a minimum change of direction of the snow as it is plowed, and a minimum of containment due to the open front and exposed vanes. Furthermore, linear polyethylene has a low coefficient of friction. Another factor is the flexibility of the paddles, which are straight statically but which free-form to a natural backward curve dynamically, and therefore readily unload snow and are diflicult to overload. These factors contribute to a conservation of energy, resulting in greater efficiency.
