Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
243 words
In a self-propelled snow vehicle which includes a frame, front steering skis, a cowl mounted on the forward end of the frame, a windshield on the cowl, and occupant accommodations immediately to the rear of the cowl: a shield for the cowl and the occupant which consists of a structure laterally trianguloid in profile which extends upwardly and rearwardly from the forward end of the vehicle to and terminates above the windshield at the forward end of the occupant accommodations and is wholly selfsupported and thus leaves the accommodations readily laterally accessible and includes an arch comprising upwardly extending legs connected by a bight which straddles and is mounted on and secured to the frame at the rear end of the cowl and defines the rear side of the structure, laterally spaced rods which extend forwardly, downwardly and convergingly from near the junctions of the legs and the bight of the arch to the frame at the forward end of the vehicle near its center and are mounted on and secured to both and thus define the inclined side of the structure, and a member which extends rearwardly and laterally between the lower portions of each of the first mentioned rods and the leg of the arch on the same side of the vehicle above the lower ends thereof and forms with the arch and the first mentioned rods a reticular structure which is self-sustaining with respect to rearwardly and laterally directed forces.
Claim 2
Dependent Claim
243 words
In a self-propelled snow vehicle which includes a frame, front steering skis, a cowl mounted on the forward end of the frame, a windshield on the cowl, and occupant accommodations immediately to the rear of the cowl: a shield for the cowl and the occupant which consists of a structure laterally trianguloid in profile which extends upwardly and rearwardly from the forward end of the vehicle to and terminates above the windshield at the forward end of the occupant accommodations and is wholly selfsupported and thus leaves the accommodations readily laterally accessible and includes an arch comprising upwardly extending legs connected by a bight which straddles and is mounted on and secured to the frame at the rear end of the cowl and defines the rear side of the structure, laterally spaced rods which extend forwardly, downwardly and convergingly from near the junctions of the legs and the bight of the arch to the frame at the forward end of the vehicle near its center and are mounted on and secured to both and thus define the inclined side of the structure, and a member which extends rearwardly and laterally between the lower portions of each of the first mentioned rods and the leg of the arch on the same side of the vehicle above the lower ends thereof and forms with the arch and the first mentioned rods a reticular structure which is self-sustaining with respect to rearwardly and laterally directed forces.
Claim 3
Dependent Claim
25 words
The self-propelled vehicle claimed in claim 1 in which each of the rearwardly and laterally extending members consists of a plurality of vertically spaced rods.
Claim 4
Dependent Claim
226 words
In a self-propelled snow vehicle which includes a frame, front steering skis, a cowl mounted on the forward end of the frame, a windshield on the cowl, and occupant accommodations immediately to the rear of the cowl: a shield for the cowl and the occupant which consists of a structure laterally trianguloid in profile which extends upwardly and rearwardly from the forward end of the vehicle to and terminates above the windshield at the forward end of the occupant accommodations and is wholly self-supported and thus leaves the accommodations readily laterally accessible and includes an arch comprising upwardly extending legs connected by a bight which straddles and is mounted on and secured to the frame at the rear end of the cowl and defines the rear side of the structure, a member which extends forwardly and downwardly from near the top of the arch to the frame at the forward end of the vehicle near its center and is mounted on and secured to both and thus define the inclined side of the structure, and a member which extends rearwardly and laterally between the lower portions of the first mentioned member and each leg of the arch above the lower ends thereof and forms with the arch and the first mentioned member a reticular structure which is self-sustaining with respect to rearwardly and laterally directed forces.
Claim 5
Dependent Claim
226 words
In a self-propelled snow vehicle which includes a frame, front steering skis, a cowl mounted on the forward end of the frame, a windshield on the cowl, and occupant accommodations immediately to the rear of the cowl: a shield for the cowl and the occupant which consists of a structure laterally trianguloid in profile which extends upwardly and rearwardly from the forward end of the vehicle to and terminates above the windshield at the forward end of the occupant accommodations and is wholly self-supported and thus leaves the accommodations readily laterally accessible and includes an arch comprising upwardly extending legs connected by a bight which straddles and is mounted on and secured to the frame at the rear end of the cowl and defines the rear side of the structure, a member which extends forwardly and downwardly from near the top of the arch to the frame at the forward end of the vehicle near its center and is mounted on and secured to both and thus define the inclined side of the structure, and a member which extends rearwardly and laterally between the lower portions of the first mentioned member and each leg of the arch above the lower ends thereof and forms with the arch and the first mentioned member a reticular structure which is self-sustaining with respect to rearwardly and laterally directed forces.
Claim 6
Dependent Claim
25 words
The self-propelled vehicle claimed in claim 3 in which each of the rearwardly and laterally extending members consists of a plurality of vertically spaced rods.
