Abstract
Abstract A snow plow alignment and storage system for aligning a snow plow with respect to the plow mounting assembly of a truck having a wheeled carrier with a frame supported on caster wheels. A jack is removably mounted on a deck of the carrier for assisting vertical alignment of the snow plow frame. The deck is large from left to right and from forward to rearward to allow the jack to be rested thereon in various positions so as to adjust for variations in plow frames of different brands. Left and right notches in the frame to receive the lower edge of a snow plow blade.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
208 words
A snow plow alignment and storage carrier for aligning the mounting apertures of a snow plow support module with cooperative apertures of a truck-mounted attachment module, said carrier comprising: a frame having wheels thereunder, a plow blade lower edge engaging means at the forward end of said frame and capable of engaging and supporting the lower edge of a plow blade when such blade is in a carrying position on said carrier, an elevating means supported by a rearward end of said carrier frame, said elevating means having a portion elevatable with respect to said carrier frame, snow plow support module engaging means attached to said elevatable portion and capable of engaging and supporting the underside of said snow plow support module while a snowplow blade is in said carrying position whereby as said elevatable portion is raised with respect to said carrier frame said support module will be raised so that said carrier with said snowplow thereon can be moved across a supporting surface thereunder so as to assist alignment of said apertures of said plow support module with said apertures of said attachment module whereby pivot pin means can be inserted through said apertures to pivotally mount said plow support module on said truck-mounted attachment module.
Claim 2
Dependent Claim
208 words
A snow plow alignment and storage carrier for aligning the mounting apertures of a snow plow support module with cooperative apertures of a truck-mounted attachment module, said carrier comprising: a frame having wheels thereunder, a plow blade lower edge engaging means at the forward end of said frame and capable of engaging and supporting the lower edge of a plow blade when such blade is in a carrying position on said carrier, an elevating means supported by a rearward end of said carrier frame, said elevating means having a portion elevatable with respect to said carrier frame, snow plow support module engaging means attached to said elevatable portion and capable of engaging and supporting the underside of said snow plow support module while a snowplow blade is in said carrying position whereby as said elevatable portion is raised with respect to said carrier frame said support module will be raised so that said carrier with said snowplow thereon can be moved across a supporting surface thereunder so as to assist alignment of said apertures of said plow support module with said apertures of said attachment module whereby pivot pin means can be inserted through said apertures to pivotally mount said plow support module on said truck-mounted attachment module.

Claim 7
Dependent Claim
44 words
The snow plow alignment and storage carrier of claim 1 wherein said jack has a handle at its upper end which is rotatable in a horizontal plane so as to be moving in an area above and not conflicting with said plow support module.
Claim 8
Dependent Claim
17 words
The snow plow alignment and storage carrier of claim 1 wherein said elevating means is a jack.
Claim 9
Dependent Claim
67 words
The snow plow alignment and storage carrier of claim 1 in further combination with said snowplow and plow support module and wherein said elevating means is a jack having a rotatable control handle, said handle being rotatable in a horizontal plane and disposed above and not conflicting with said plow support module when said plow and plow support module are on said carrier in said carrying position.
Claim 10
Dependent Claim
96 words
The snow plow alignment and storage carrier of claim 8 wherein, said carrier having a straight reference line extending from right to left substantially at the forward side of said carrier frame, said carrier having a center line extending forwardly and rearwardly of said carrier frame and through the center there of, said carrier having a jack-supporting deck at its rearward end on which said jack is movably rested, said deck having a forward edge which is within substantially 17 inches of the forward side of said frame as measured along said centerline of said carrier.
Claim 11
Dependent Claim
96 words
The snow plow alignment and storage carrier of claim 8 wherein said carrier has a straight reference line extending from right to left substantially at the forward side of said carrier frame, said carrier having a center line extending forwardly and rearwardly of said carrier frame and through the center thereof, said carrier having a jack-supporting deck at its rearward end on which said jack is movably rested, said deck having a rearward edge which is at least substantially 29 inches from the forward side of said frame as measured along said centerline of said carrier.
Claim 12
Dependent Claim
38 words
The snow plow alignment and storage carrier of claim 10 wherein said jack has a lower telescoping portion, said deck having a left-to-right dimension which is at least substantially double the left-to-right dimension of said lower telescoping portion.
Claim 13
Dependent Claim
38 words
The snow plow alignment and storage carrier of claim 8 wherein said jack has a lower telescoping portion, said deck having a left-to-right dimension which is at least substantially double the left-to-right dimension of said lower telescoping portion.
Claim 14
Dependent Claim
115 words
The snow plow alignment and storage carrier of claim 1 wherein at least one upwardly projecting blade retainer flange is attached to a forward portion of said carrier frame to retain said plow on said carrier, spaced upwardly projecting guide flange means disposed spaced behind said retainer flange so as to provide a notch therebetween, the forward side of said guide flange means having an inclination at an acute angle with respect to the vertical so as to incline downwardly and forwardly as its lower end is approached from its upper end so that when a downwardly moving blade edge strikes said guide flange the blade edge will be deflected and guided forwardly and downwardly.
