Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
217 words
A power take-off assembly mountable within a vehicle engine compartment for an engine having a transversely extended radiator located adjacent the front end of the compartment and a crank shaft projected forwardly from the front end of the engine toward the radiator, said assembly comprising: a. an elongated flat hollow housing member, b. a pair of shafts rotatably supported at opposite ends of said housing, each shaft having one end thereof projected outwardly from one side of said housing, c. a pair of gears within said housing corresponding to and mounted on said shafts, d. an endless chain means in continuous meshed engagement with said pair of gears, e. means for mounting said housing member in an upright position on the front end of said engine and rearwardly of the radiator with the one side of the housing member facing the engine and the one end of a first one of said shafts arranged in axial alignment with said crank shaft, f. coupling means for connecting the crank shaft in a driving relation with said first shaft, g. a hydraulic motor mounted on said housing adjacent the one end of the second one of said shafts, and h. means for releasably coupling said hydraulic motor in a driven relation with the one end of said second shaft.
Claim 2
Dependent Claim
217 words
A power take-off assembly mountable within a vehicle engine compartment for an engine having a transversely extended radiator located adjacent the front end of the compartment and a crank shaft projected forwardly from the front end of the engine toward the radiator, said assembly comprising: a. an elongated flat hollow housing member, b. a pair of shafts rotatably supported at opposite ends of said housing, each shaft having one end thereof projected outwardly from one side of said housing, c. a pair of gears within said housing corresponding to and mounted on said shafts, d. an endless chain means in continuous meshed engagement with said pair of gears, e. means for mounting said housing member in an upright position on the front end of said engine and rearwardly of the radiator with the one side of the housing member facing the engine and the one end of a first one of said shafts arranged in axial alignment with said crank shaft, f. coupling means for connecting the crank shaft in a driving relation with said first shaft, g. a hydraulic motor mounted on said housing adjacent the one end of the second one of said shafts, and h. means for releasably coupling said hydraulic motor in a driven relation with the one end of said second shaft.
Claim 3
Dependent Claim
109 words
The combination according to claim 1 wherein: a. said coupling means includes a first coupling member detachably mounted on said crank shaft and a second coupling member rigidly secured to said first shaft, b. each of said coupling members having a series of circumferentially spaced axially extended abutment portions projected outwardly from the adjacent sides thereof, and c. a third coupling member having a plurality of radially projected circumferentiaLly spaced abutment fingers, d. said third coupling member interposed between and in axial alignment with said first and second coupling members with the abutment fingers thereof in interlocked engagement with the abutment portions on said first and second coupling members.
Claim 4
Dependent Claim
173 words
The combination according to claim 1 wherein: a. said hydraulic motor has a main shaft with an end section projected from the side thereof facing said housing, said end section having the outer peripheral surface thereof formed with a plurality of circumferentially spaced axially extended external splines, and b. said one end of the second shaft being of a cylindrical tubular shape having an axial bore with an inner portion of a reduced diameter relative to the outer portion thereof, said inner portion having the side wall thereof formed with a plurality of circumferentially spaced axially extended internal splines corresponding to said external splines, c. means mounting the gear on said second shaft for relative axial movement, and d. means for axially moving said second shaft relative to said main shaft to a first position wherein said splines are in interlocked engagement, and to a second position wherein the internal splines are withdrawn from said external splines and in bearing engagement with the side wall of said outer portion of the axial bore.
Claim 5
Dependent Claim
46 words
The combination according to claim 3 wherein: a. said means for axially moving the second shaft includes an operating lever movably supported on said housing member, and b. means for moving said operating lever including an actuator member mounted in the operator compartment of the vehicle.
