Abstract
Abstract A bow guide and support mechanism adapted for transverse mounting near the front end of a boat trailer frame-work is described. The support mechanism comprises a V-block member symmetrically affixed against one side of which is an elongated cylindrical guide member bent to define an obtuse angle of somewhat lesser included angle than that defined by the V-block member, the cylindrical guide member having its apex portion lying below the apex of the included angle of the V-block member and being so positioned that outwardly extending arm portions of the cylindrical guide member project upwardly from and with respect to outer surface portions of the V-block member defining its obtuse angle. The outwardly extending arm portions of the cylindrical guide member extend substantially beyond the transverse outer ends of the V-block member at each side of the trailer to serve as extended guide means for centering the bow of a boat to be trailered upon the V-block member when being loaded.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
In a bow guide and support mechanism for boat trailers of the type comprising a trailer framework having chock means along its length for supporting a boat to be trailered, the improvement comprising; auxiliary chock means comprising a V-block member adapted to be transversely secured to the trailer framework near the front end thereof and a cylindrical guide member centrally bent to define an obtuse angle of somewhat lesser included angle then that defined by the V-block member, means for securing said cylindrical guide member against one side of said V-block member in symmetrical relation with respect thereto with its apex portion below the apex of the included angle of said V-block member and so positioned that outwardly-extending arm portions of said cylindrical guide member project upwardly of respective outer surface portions of said V-block member defining said obtuse angle, said outwardly-extending arm portions of said cylindrical guide member extending substantially beyond the transverse outer ends of said V-block member at each side of the trailer to serve as extended guide means for centering the bow of a boat to be trailered upon said V-block member when being loaded.
Claim 2
Dependent Claim

In a bow guide and support mechanism for boat trailers of the type comprising a trailer framework having chock means along its length for supporting a boat to be trailered, the improvement comprising; auxiliary chock means comprising a V-block member adapted to be transversely secured to the trailer framework near the front end thereof and a cylindrical guide member centrally bent to define an obtuse angle of somewhat lesser included angle then that defined by the V-block member, means for securing said cylindrical guide member against one side of said V-block member in symmetrical relation with respect thereto with its apex portion below the apex of the included angle of said V-block member and so positioned that outwardly-extending arm portions of said cylindrical guide member project upwardly of respective outer surface portions of said V-block member defining said obtuse angle, said outwardly-extending arm portions of said cylindrical guide member extending substantially beyond the transverse outer ends of said V-block member at each side of the trailer to serve as extended guide means for centering the bow of a boat to be trailered upon said V-block member when being loaded.
Claim 3
Dependent Claim
45 words
A bow guide support mechanism for boat trailers as defined in claim 1, wherein said cylindrical guide member is formed of metal tubing, and a pair of synthetic plastic sleeves friction-fitted over said outwardly-extending arm portions of said guide member for minimizing sliding friction thereover.
Claim 4
Dependent Claim
49 words
A bow guide support mechanism for boat trailers as defined in claim 2, wherein said V-block member is formed of wood and wherein said outer surface portions of said V-block member defining said obtuse angle are covered with sheet synthetic plastic material presenting a low coefficient of sliding friction.
Claim 5
Dependent Claim
37 words
A bow guide support mechanism for boat trailers as defined in claim 3, including a cylindrical end cap secured in place over the outer end of each of said outwardly-extending arm portions of said cylindrical guide member.
