Patent number: 7347014Abstract: A snowplow includes a blade and bottom plate with a mounting plate bolted to an end portion of the bottom plate. A channel bracket is fixed to the mounting plate with its flanges extending forward and its web thereby spaced forward of the mounting plate to form a pad plate. A resilient rubber pad, larger than the pad plate, is removably mounted on the pad plate to extend inward, outward, upward and downward from it. The rubber pad is invertible and reversible on the pad plate. The planes of the pad plate and of the rubber pad are skewed inward and downward relative to the plane of the mounting plate. The bottom plate includes spaced bolt holes for selective positioning of the mounting plate relative to the bottom plate for variable plow width.Type: GrantFiled: February 24, 2005Date of Patent: March 25, 2008Inventor: Richard J. Fiandach

Publication number: 20070169384Abstract: A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle. This pusher allows a work vehicle to capture, contain, and relocate large amounts of snow very quickly and efficiently. The attachment consists of side panels, connected by horizontal members between. This pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The attachment does not require the operator to exit the work vehicle to secure or release it from the snowplow. Accordingly, the attachment allows the quick and repeated conversion of a snow plow into a snow pusher box and visa versa.Type: ApplicationFiled: January 17, 2007Publication date: July 26, 2007Inventor: Michael Stephan

Patent number: 7107710Abstract: A frontward blade mounting bracket, for connecting the front end of a side blade to a vehicle side adjacent a road surface, includes a spacer and an elongate guide member. The spacer has opposed first and second spacer ends. The first spacer end is pivotally connected to the vehicle side about a substantially vertical pivot axis, and the second spacer end is spaced apart from the first spacer end in a direction leading outwardly away from the vehicle side. The guide member has first and second guide parts connected to the second spacer end and the second guide part respectively. The first and second guide parts longitudinally move relative to one another about a substantially vertical guide axis.Type: GrantFiled: May 24, 2004Date of Patent: September 19, 2006Inventor: Normand Savard

Patent number: 7100314Abstract: A plow blade float attachment for preventing damage to a side deflector on a plow blade. The plow blade float attachment includes an arm member pivotally attached to a deflector member of a plow blade, a contact member attached to the arm member, a guide member attached to the deflector member for slidably receiving a distal portion of the arm member, and a bias member attached between the deflector member and the arm member for applying a downward bias force to the arm member.Type: GrantFiled: June 5, 2004Date of Patent: September 5, 2006Inventor: Leland E. Jensen

Patent number: 7000338Abstract: A device for selectively positioning a side wing relative to the side of a motor vehicle it is mounted on and to the adjacent road surface is disclosed. The device includes first and second longitudinal end members pivotally connected to the vehicle side and to a rearward end of the side wing about vertical axes; the front end of the wing is usually connected adjacent the front end of the vehicle. First and second elongate rams that are angularly positioned relative to one another are connected to the first and second end members. The first and second rams operate in parallel relative to each other for selective operation of the side wing from a position adjacent the vehicle side and away from the ground surface to a position in operative engagement with the road surface at an adjustable angle relative to the vehicle side.Type: GrantFiled: May 4, 2004Date of Patent: February 21, 2006Inventor: Normand Savard

Patent number: 6941686Abstract: A side plow assembly for use on a vehicle, including a plowshare, the horizontal and vertical positioning which can be controlled independently of each other. The side plow assembly also includes an attachment device that allow it to be quickly attached to and detached from the plow vehicle. The front attachment devices are specifically designed to minimize binding when the plow assembly's plowshare is raised or lowered.Type: GrantFiled: October 10, 2003Date of Patent: September 13, 2005Inventor: Patrick Cusick

Patent number: 6883436Abstract: A rail ballast wing assembly includes a outer door with at least one hinge edge, a template door pivotably secured to least one of the hinge edges and a positioning device associated with the outer door and the template door for maintaining an angular orientation of the template door relative to the outer door. A breakaway mechanism is connected to the positioning device and the template door and configured for temporarily disengaging the template door from the positioning device upon exposure to impact forces. The breakaway mechanism preferably includes a plate connecting the positioning device to the template door, and being disengageable from the template door. A top pin on the outer door is pivotably secured to a top plate through the use of at least one retainer bracket.Type: GrantFiled: May 28, 2003Date of Patent: April 26, 2005Assignee: Nordco Inc.Inventor: James William Fuerst

Patent number: 6877258Abstract: The plow includes a vehicle mount for mounting the plow to a host vehicle, and a main blade mounted to the vehicle mount The plow further includes a pair of wing blades pivotally mounted to the main blade for travel in an arcuate path relative to the main blade, and four bar parallel arm linkages and actuators connected between opposing ends of the main blade and each of the wing blades for supporting and swinging the at least one wing blade in said arcuate travel path throughout the full distance between a retracted position in front of the main blade such that at least a substantial portion of the at least one wing blade is disposed in overlapping relation with the main blade, and an extended position in substantial longitudinal alignment with the main blade whereby a plurality of plowing widths is provided. It should be noted that the blade is advantageously used for the plowing of snow, however the plowing of other materials is envisioned such as sand or gravel.Type: GrantFiled: August 9, 2002Date of Patent: April 12, 2005Assignee: Agway ManufacturingInventor: Oscar Frey

Publication number: 20040216333Abstract: A plow assembly includes a pair of plow wings which are pivotally mounted at opposite ends of a center plow. Each of the plow wings may pivot between a forwardly angled position and an aligned position. The plow assembly may pivot a trailing plow wing in response to the center plow being urged or angled toward that side of the vehicle. The plow wings may be oriented in their forwardly angled position until the center plow is at least substantially urged or pivoted toward its angled position or toward a position between the center position and the angled position. The trailing plow wing may be pivoted or urged to its aligned position in response to the center plow being substantially urged or pivoted toward its angled position or toward a position between its center position and its angled position.Type: ApplicationFiled: April 29, 2004Publication date: November 4, 2004Inventors: Philip J. Quenzi, Cal G. Niemela, Nels A. Niemela
