Abstract
Abstract This invention relates to multipurpose, self-propelled utility vehicles of the two axle type comprising a chassis, a driving mechanism unit disposed transversely to the vehicle''s longitudinal axis and mounted on said chassis intermediate the two wheel axles, wherein said mechanism comprises a fuel-burning engine and a gear shift drive or transmission disposed within a troughlike cruciform frame, and power takeoff and hoist means projecting from substantially the center of said chassis along the longitudinal axis of said vehicle, and selectively operable by V-belt pulley members. The purpose of the above abstract is to provide a nonlegal technical statement adapted to serve as a searching-scanning tool for scientists, engineers and researchers. Accordingly, this abstract is not intended to limit the scope of the invention, hereinafter described in detail, nor is it intended to be used in interpreting or in any way limiting the scope or fair meaning of the claims appended hereto.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
241 words
In combination with a vehicle of the type having a chassis and at least two longitudinally spaced wheels supporting axle means; a driving mechanism fixedly supported relative to the chassis intermediate the at least two axle means, which includes a fuel-burning engine and a main transmission driven thereby; a final drive means for driving the wheels on at least one of said axle means; connecting means drivingly connecting said main transmission and said final drive means; and at least one power takeoff mechanism also supported by the chassis; an improvement which comprises a power takeoff transmission powered from said engine and independently of said final drive means and including a disengageable clutch, and means connected to said clutch and engine for driving the former from the latter, an auxiliary shaft means having one end drivingly connected to said clutch, a gear case connected to the opposite end of said auxiliary shaft means, and an output member extending outward of said case and generally parallel to said at least one power takeoff mechanism and driven from said auxiliary shaft means; means mounting said at least one power takeoff transmission generally centrally of said at least two longitudinally spaced axle means; and additional connecting means drivingly connecting said output member and said at least one power takeoff mechanism; the connecting means, said additional connecting means, and said output member lying substantially in the middle of the vehicle and along the longitudinal direction thereof.
Claim 2
Dependent Claim
241 words
In combination with a vehicle of the type having a chassis and at least two longitudinally spaced wheels supporting axle means; a driving mechanism fixedly supported relative to the chassis intermediate the at least two axle means, which includes a fuel-burning engine and a main transmission driven thereby; a final drive means for driving the wheels on at least one of said axle means; connecting means drivingly connecting said main transmission and said final drive means; and at least one power takeoff mechanism also supported by the chassis; an improvement which comprises a power takeoff transmission powered from said engine and independently of said final drive means and including a disengageable clutch, and means connected to said clutch and engine for driving the former from the latter, an auxiliary shaft means having one end drivingly connected to said clutch, a gear case connected to the opposite end of said auxiliary shaft means, and an output member extending outward of said case and generally parallel to said at least one power takeoff mechanism and driven from said auxiliary shaft means; means mounting said at least one power takeoff transmission generally centrally of said at least two longitudinally spaced axle means; and additional connecting means drivingly connecting said output member and said at least one power takeoff mechanism; the connecting means, said additional connecting means, and said output member lying substantially in the middle of the vehicle and along the longitudinal direction thereof.
Claim 3
Dependent Claim
33 words
The invention as set forth in claim 1, wherein said mounting means includes first frame means connected to the chassis including a cruciform member mounted transversely to the longitudinal axis on the vehicle.
Claim 4
Dependent Claim
25 words
The invention as set forth in claim 2, wherein said cruciform frame member is made troughlike and said trough is reinforced with tubular profile beams.
Claim 5
Dependent Claim
31 words
The invention as set forth in claim 3, wherein said mounting means includes a second frame means contiguoUs with said first frame means and is fabricated of boxlike, longeron frame members.
Claim 6
Dependent Claim
37 words
The improvement of claim 4, wherein said final drive means includes an axle drive means for driving the axle-supported wheels and wherein said boxlike frame members generally surround said driving mechanism, connecting means, and final drive means.
Claim 7
Dependent Claim
17 words
The invention set forth in claim 4, wherein said longeron frame members are generally rectangular in shape.
Claim 8
Dependent Claim
28 words
The invention as set forth in claim 1, wherein said driving unit has a longitudinal axis, said axis being orientated transversely to the longitudinal axis of the vehicle.
Claim 9
Dependent Claim
81 words
The invention as set forth in claim 1, further including a second power takeoff mechanism; said at least one power takeoff mechanism and said second power takeoff mechanism located at opposite ends of the vehicle; said gear case including a second output member also driven from said auxiliary shaft and extending outwardly from said gear case toward and generally parallel to said second takeoff mechanism; and further connecting means drivingly connecting said second output member and said additional power takeoff mechanism.
Claim 10
Dependent Claim
52 words
The invention as set forth in claim 8, wherein said additional and further connecting means includes shafts each having a driven end articulated to a corresponding output member; and displaceable sleeve means interposed between said auxiliary shaft and said output members for engaging and disengaging said output members from said auxiliary shaft.
Claim 11
Dependent Claim
30 words
The invention as set forth in claim 9, wherein said articulated shafts being set at an angle of 10* to 25* inclination relative to the longitudinal axis of the vehicle.
Claim 12
Dependent Claim
73 words
The invention as set forth in claim 1, wherein said wheel-supporting axle means are front and rear axles; said final drive means includes axle drive means in said front and rear axles to power the wheels mounted thereon, and said connecting means drivingly connect said axle drive means to said main transmission; and said wheel-supporting front and rear axle means and final drive means therefor being constructed of substantially mirror image structural elements.
