Abstract
Abstract The chassis member is formed from a sheet of metallic material into a structure having an upper planar surface of elongated rectangular outline and a pair of downward extending planar side portions of elongated rectangular outline. The undercarriage assemblies are secured to the underside of the chassis member, that is both to the rectangular planar member and to the rectangular side portion. Front section and midsection members are secured to the top side of the chassis member to support the functional mechanical and electrical elements of the tractor as well as to provide a rugged structure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
345 words
In a powered traction vehicle wherein a front wheel assembly is pivotally mounted to a support member which is secured to a chassis, and the housing of a rear wheel assembly is secured to said chassis, said chassis comprising: a. an upper planar portion of elongated rectangular outline; b. a pair of side planar portions of elongated rectangular outline, each of said side planar portions extending orthogonally downward from a respective long side of said upper planar portion; c. a pair of lower planar portions of elongated rectangular outline, each of said lower planar portions extending orthogonally inward from the lower side of a respective side portion, the short sides of said side planar portions and said lower planar portions being substantially smaller than the short side of said upper planar portion; d. each of said portions being integral with one another, and the long sides of said portions being parallel to one another; e. a pair of elongated planar elements extending inwardly into said chassis from at least one end thereof parallel to said side planar portions, each of said elements being rigidly secured to said upper planar portion and one of said lower planar portions and spaced from said side planar portion to provide a channel adapted to receive a mating prong member, the pair of channels thus formed at the end of said chassis providing means for facilitating attachment of accessories apparatus comprising a pair of mating prongs; f. an end seal member comprising a planar portion of substantially elongated rectangular outline secured to said planar elements and extending orthogonally downward from a short side of said upper planar portion, said end member exhibiting a pair of channel openings, each of said openings registering with one of said pair of channels; g. said support member extending substantially in a direction parallel to a short side of said upper planar portion and secured at each end thereof to said chassis near a short side of said upper planar portion, and h. said housing element being secured at each side thereof to said chassis.
Claim 2
Dependent Claim
345 words
In a powered traction vehicle wherein a front wheel assembly is pivotally mounted to a support member which is secured to a chassis, and the housing of a rear wheel assembly is secured to said chassis, said chassis comprising: a. an upper planar portion of elongated rectangular outline; b. a pair of side planar portions of elongated rectangular outline, each of said side planar portions extending orthogonally downward from a respective long side of said upper planar portion; c. a pair of lower planar portions of elongated rectangular outline, each of said lower planar portions extending orthogonally inward from the lower side of a respective side portion, the short sides of said side planar portions and said lower planar portions being substantially smaller than the short side of said upper planar portion; d. each of said portions being integral with one another, and the long sides of said portions being parallel to one another; e. a pair of elongated planar elements extending inwardly into said chassis from at least one end thereof parallel to said side planar portions, each of said elements being rigidly secured to said upper planar portion and one of said lower planar portions and spaced from said side planar portion to provide a channel adapted to receive a mating prong member, the pair of channels thus formed at the end of said chassis providing means for facilitating attachment of accessories apparatus comprising a pair of mating prongs; f. an end seal member comprising a planar portion of substantially elongated rectangular outline secured to said planar elements and extending orthogonally downward from a short side of said upper planar portion, said end member exhibiting a pair of channel openings, each of said openings registering with one of said pair of channels; g. said support member extending substantially in a direction parallel to a short side of said upper planar portion and secured at each end thereof to said chassis near a short side of said upper planar portion, and h. said housing element being secured at each side thereof to said chassis.
Claim 3
Dependent Claim
26 words
The combination of claim 1 wherein said end seal member and said elongated planar elements are constituted of folded portions integral with said upper planar portion.
Claim 4
Dependent Claim
145 words
An electrically propelled tractor comprising the combination of claim 1 wherein a first rigid member of generally rectangular outline is transversely secured to the top side of said upper planar portion in a central region thereof, the width of said first rigid member being less than the width of said upper portion, and bearing means in the side of said first rigid member opposite the side secured to said upper planar portion for supporting the upper portion of a steering shaft, a second rigid member of generally rectangular outline transversely secured to the top side of said upper planar portion adjacent the short side thereof near the said support member, the width of said second rigid member being comparable to the width of said first rigid member, means including said upper planar portion and said rigid members for providing a battery compartment for said vehicle.
Claim 5
Dependent Claim
33 words
The combination of claim 3 in which an electric drive motor is provided mounted to the under side of said upper portion and mechanically coupled to the axles of said rear wheel assembly.
Claim 6
Dependent Claim
12 words
The combination of claim 3 in which said rigid members are castings.
