Abstract
Abstract Bale loading assembly for round bales of hay or the like is arranged at the front end of a movable platform of the type having a downwardly and forwardly sloping ramp. The invention provides bale pulling means arranged to be lowered down, to engage the bale and move same up the ramp onto the platform. The pulling means thus renders the above type of movable platform suitable even for operation in a hilly terrain.

Claim 1
Independent Claim
428 words
Bale loading assembly for use with a bale loader for handling bales of hay or the like, said bale loader being of the type of a mobile platform of an elongated, generally rectangular shape including two sides and a loading front end, said bale loading assembly comprising: a. ramp means pivotally secured to said loading front end for pivotal movement about a first lateral axis generally coincident with said front end, said ramp means normally being inclined downwardly and forwardly of said front end of the platform; b. a first drive means operatively connected to said ramp means for selectively adjusting the inclination of said ramp means; c. bale pulling means including bale engagement means secured to one end of said bale pulling means and having an extended position forwardly and in a surrounding posture of said bale, a ground engaging position and a retracted position, said bale engagement means including a pair of arms for simultaneous generally pivotal movement operatively about a second lateral axis generally parallel with said first lateral axis in planes generally coincident with planes perpendicular to said platform and located adjacent to said sides of the platform, said pair of arms having free ends, and said bale engagement means further including ground engagement means mounted on free ends of said pair of arms; d. second drive means operatively connected to said bale pulling means for selectively displacing said bale engagement means from said extended position wherein said bale engagement means is located ahead of said front end in a generally co-planar relationship with said mobile platform, to said ground engaging portion, wherein said bale engagement means is located ahead of said front end at the ground level, and to said retracted position wherein said bale engagement means is generally co-planar with said platform and located on said platform adjacent said front end thereof, said second drive means further including a pair of levers, each of said pair of levers being secured with its one end, to one side of the platform for pivotal movement about said second lateral axis and in a plane generally perpendicular to said platform and located at the respective side thereof, the opposite end of each of said levers being pivotally secured by a pivot joint to the respective ends of said arms remote from said free ends thereof; and e. guide means operatively connected to said bale pulling means to guide movement of said bale engagement means from said ground engaging position to said retracted position along a locus generally parallel with the inclination of said ramp means.

Bale loading assembly for use with a bale loader for handling bales of hay or the like, said bale loader being of the type of a mobile platform of an elongated, generally rectangular shape including two sides and a loading front end, said bale loading assembly comprising: a. ramp means pivotally secured to said loading front end for pivotal movement about a first lateral axis generally coincident with said front end, said ramp means normally being inclined downwardly and forwardly of said front end of the platform; b. a first drive means operatively connected to said ramp means for selectively adjusting the inclination of said ramp means; c. bale pulling means including bale engagement means secured to one end of said bale pulling means and having an extended position forwardly and in a surrounding posture of said bale, a ground engaging position and a retracted position, said bale engagement means including a pair of arms for simultaneous generally pivotal movement operatively about a second lateral axis generally parallel with said first lateral axis in planes generally coincident with planes perpendicular to said platform and located adjacent to said sides of the platform, said pair of arms having free ends, and said bale engagement means further including ground engagement means mounted on free ends of said pair of arms; d. second drive means operatively connected to said bale pulling means for selectively displacing said bale engagement means from said extended position wherein said bale engagement means is located ahead of said front end in a generally co-planar relationship with said mobile platform, to said ground engaging portion, wherein said bale engagement means is located ahead of said front end at the ground level, and to said retracted position wherein said bale engagement means is generally co-planar with said platform and located on said platform adjacent said front end thereof, said second drive means further including a pair of levers, each of said pair of levers being secured with its one end, to one side of the platform for pivotal movement about said second lateral axis and in a plane generally perpendicular to said platform and located at the respective side thereof, the opposite end of each of said levers being pivotally secured by a pivot joint to the respective ends of said arms remote from said free ends thereof; and e. guide means operatively connected to said bale pulling means to guide movement of said bale engagement means from said ground engaging position to said retracted position along a locus generally parallel with the inclination of said ramp means.
Claim 3
Dependent Claim
27 words
An assembly as claimed in claim 1 in which said ground engagement means includes a roller rotatably supported on the free ends of said pair of arms.
Claim 4
Dependent Claim
21 words
An assembly as claimed in claim 1 including motor means for selectively and simultaneously pivoting said levers about the second axis.
Claim 5
Dependent Claim
55 words
An assembly as claimed in claim 1 wherein said guide means further includes means for changing location of said bale engagement means from said extended position to said ground engaging position by a generally pivotal movement of said bale pulling means about a third lateral axis generally coincident with the front end of said platform.
Claim 6
Dependent Claim
30 words
An assembly as claimed in claim 4 including means to support each of said pair of arms for pivotal sliding movement, said support means being located on said third axis.
Claim 7
Dependent Claim
73 words
An assembly as claimed in claim 5, wherein the distance between said second axis and the axis of pivot joints at which each of the respective levers is pivotally secured to the associated arm is shorter than the distance between said second axis and said third axis, whereby said first position is achieved when said levers are turned into a forwardmost position in which said pivot joints are generally coincident with said platform.
Claim 8
Dependent Claim
34 words
An assembly as claimed in claim 6, wherein said bale engagement means further includes a laterally extending rod. generally parallel with and spaced above said roller, said rod being fixedly secured to said arms.
