Abstract
Abstract A snowplow deflector assembly is attachable to that type of snowplow which is mounted on the front end of a vehicle. The deflector assembly comprises a deflector member which is supported to extend over the top of the blade of the snowplow to deflect snow moving off the top of the blade, that snow being thereby substantially prevented from being thrown against the windshield of the vehicle and obstructing the view of a driver. Two embodiments of the invention are described.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
136 words
A snowplow attachment comprising: a frame adapted to be attached to the front of a vehicle; a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon; a second support member pivotally connected to an upper portion of the frame; actuator means for simultaneous manipulation of said first and second support members; and, a deflector assembly fixed to said second support member and including a deflector member extending forwardly of the second support member over the top of said blade to thereby form a gap between the deflector member and the scraper blade, whereby when the vehicle is driven across a snow-covered surface, a substantial portions of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 2
Dependent Claim
136 words
A snowplow attachment comprising: a frame adapted to be attached to the front of a vehicle; a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon; a second support member pivotally connected to an upper portion of the frame; actuator means for simultaneous manipulation of said first and second support members; and, a deflector assembly fixed to said second support member and including a deflector member extending forwardly of the second support member over the top of said blade to thereby form a gap between the deflector member and the scraper blade, whereby when the vehicle is driven across a snow-covered surface, a substantial portions of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 3
Dependent Claim
21 words
The snowplow attachment of claim 1 wherein the deflector member is horizontally adjustable relative to the top of the scraper blade.
Claim 4
Dependent Claim
17 words
The snowplow attachment of claim 1, wherein the deflector assembly is welded to the second support member.
Claim 5
Dependent Claim
137 words
A snowplow attachment comprising: a frame adapted to be attached to the front of a vehicle; a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon; a second support member pivotally connected to an upper portion of the frame; actuator means for simultaneous manipulation of said first and second support members; and, a deflector assembly connected to said first and second support members and including a deflector member extending forwardly of the support members over the top of said blade to thereby form a gap between the deflector member and the scraper blade, whereby when the vehicle is driven across a snow-covered surface, a substantial portion of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 6
Dependent Claim
137 words
A snowplow attachment comprising: a frame adapted to be attached to the front of a vehicle; a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon; a second support member pivotally connected to an upper portion of the frame; actuator means for simultaneous manipulation of said first and second support members; and, a deflector assembly connected to said first and second support members and including a deflector member extending forwardly of the support members over the top of said blade to thereby form a gap between the deflector member and the scraper blade, whereby when the vehicle is driven across a snow-covered surface, a substantial portion of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 7
Dependent Claim
21 words
The snowplow attachment of claim 4, wherein the deflector member is horizontally adjustable relative to the top of the scraper blade.
Claim 8
Dependent Claim
32 words
The snowplow attachment of claim 4, wherein the deflector member is pivotally connected to the first support member and suspended by suspension means from a bar extending from the second support member.
Claim 9
Dependent Claim
159 words
A snowplow deflector assembly connectable to a snowplow apparatus of the type that comprises a frame adapted to be attached to the front of a vehicle, a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon, a second support member pivotally connected to an upper portion of the frame and actuator means for simultaneous manipulation of said first and second support members, said snowplow deflector assembly comprising: a deflector member fixed to said second support member at a location to the rear of said scraper blade, the deflector member extending forwardly of the second support member over the top of said blade to thereby form a gap between the deflector member and the scraper blade whereby when the vehicle is driven across a snow-covered surface, a substantial portion of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 10
Dependent Claim
159 words
A snowplow deflector assembly connectable to a snowplow apparatus of the type that comprises a frame adapted to be attached to the front of a vehicle, a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon, a second support member pivotally connected to an upper portion of the frame and actuator means for simultaneous manipulation of said first and second support members, said snowplow deflector assembly comprising: a deflector member fixed to said second support member at a location to the rear of said scraper blade, the deflector member extending forwardly of the second support member over the top of said blade to thereby form a gap between the deflector member and the scraper blade whereby when the vehicle is driven across a snow-covered surface, a substantial portion of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector member.
Claim 11
Dependent Claim
22 words
The snowplow deflector assembly of claim 7, wherein the deflector member is horizontally adjustable relative to the top of the scraper blade.
Claim 12
Dependent Claim
18 words
The snowplow deflector assembly of claim 7, wherein the deflector assembly is welded to the second support member.
Claim 13
Dependent Claim
173 words
A snowplow deflector assembly connectable to a snowplow apparatus of the type that includes a frame adapted to be attached to the front of a vehicle, a first support member pivotally connected to a lower portion of the frame and having a scraper blade attached thereon, a second support member pivotally connected to an upper portion of the frame, and actuator means for simultaneous manipulation of said first and second support members, said snowplow deflector assembly comprising: a deflector member suspended by suspension means from a bar extending from the second support member and pivotally connected to said first support member at a location to the rear of said scraper blade, the deflector member extending forwardly of the support members over the top of said blade to thereby form a gap between the deflector member and the scraper blade whereby when the vehicle is driven across a snow-covered surface, a substantial portion of any snow leaving the top of the blade is drawn into the gap between the blade and the deflector means.
