Self-loading refuse vehicle

Claim 2

In a self-loading vehicle, a bucket assembly including a bucket carried by arma extending from a shaft and positioned along a longitudinally extending axis, means mounting said bucket assembly for pivotal movement about said longitudinally extending axis between a lower materialreceiving position and an upper material-discharging position, locking means normally retaining said bucket in a fixed position with respect to said bucket assembly, and vehicle mounted actuating means contacting said locking means in said upper discharge position whereby said bucket is released to pivot with respect to said bucket assembly and compress material in said vehicle.

Claim 3

Apparatus as set out in claim 1 further comprising guide means mounted on said vehicle and cooperating with said bucket to determine the amount of pivotal movement of the bucket during the compressing operation.

Claim 4

Apparatus as set out in claim 1 wherein said locking means comprises a lever having one end pivotally mounted to said bucket and the other end cooperating with an abutment formed on one of said arms.

Claim 5

Apparatus as set out in claim 3 wherein said actuating means comprise a projecting arm attached to a wall of the vehicle and adapted to engage with said lever in the discharge position of said bucket to move said other end of the lever away from its cooperating abutment.

Claim 6

Apparatus as set out in claim 4 wherein said guide means is attached to a wall of the vehicle, a projection being formed at one side of said bucket to cooperate with said guide means as the bucket moves to the discharge position whereby the bucket is tilted to advance the lower portion further into the body of the vehicle.

Claim 7

Apparatus as set out in claim 1 further comprising hydraulic means for actuating said shaft.

Claim 8

Apparatus as set out in claim 6 further comprising a hold down bar operatively connected to said shAft to be retracted in the bucket material-discharge position.

Claim 9

Apparatus as set out in claim 6 wherein said hydraulic means comprises a hydraulic cylinder having a pair of pulleys mounted on the piston thereof, a pulley wheel mounted on the end of said shaft and a cable fastened to the vehicle body at one end and passing around one of said pulleys, said pulley wheel and the other of said pulleys and also fastened at its other end to the vehicle body whereby actuation of the piston causes rotation of said shaft.

Claim 10

Apparatus as set out in claim 3 wherein said locking means retain said bucket abuting against said arms and the bucket is free for rotation in one direction only when the locking means is released.

Claim 11

A self-loading vehicle comprising, a longitudinally extending shaft mounted on a side wall of the vehicle body, a bucket assembly having a lower material-receiving position and an upper material-discharging position, said assembly including, a plurality of arms each having one end fixed to said shaft and extending radially therefrom, a bucket mounted for rotation about an axis extending through the other ends of said arms and having a projection formed at one side thereof, locking means, normally retaining said bucket in a fixed position with respect to said bucket assembly, comprising, a lever having one end pivotally mounted to a side of said bucket and a pin extending from the other end to cooperate with an abutment formed on one of said arms, an actuating means comprising, a projecting arm attached to a wall of said vehicle and adapted to engage said lever when said bucket is in said upper material-discharging position to move said pin away from said abutment, a cam groove formed in a wall of said vehicle body to cooperate with said projection on said bucket as said bucket moves to the discharge position whereby said bucket is tilted to advance its lower portion further into the vehicle body, hydraulic means for actuating said shaft including, a hydraulic cylinder, a pair of pulleys mounted on the piston rod thereof, a pulley wheel mounted on the end of said shaft, and a cable fastened to the vehicle body at one end and passing around one of said pulleys, said pulley wheel, and the other of said pulleys and fastened to the vehicle body at its other end, and a hold down bar connected to said pulley wheel to be retracted in the material-diacharging position of said bucket assembly.

Claim 12

A self-loading vehicle comprising, a longitudinally extending shaft mounted on a side wall of the vehicle body, a bucket assembly having a lower material-receiving position and an upper material-discharging position, said assembly including, a plurality of arms each having one end fixed to said shaft and extending radially therefrom, a bucket mounted for rotation about an axis extending through the other ends of said arms and having a projection formed at one side thereof, locking means, normally retaining said bucket in a fixed position with respect to said bucket assembly, comprising, a lever having one end pivotally mounted to a side of said bucket and a pin extending from the other end to cooperate with an abutment formed on one of said arms, an actuating means comprising, a projecting arm attached to a wall of said vehicle and adapted to engage said lever when said bucket is in said upper material-discharging position to move said pin away from said abutment, a cam groove formed in a wall of said vehicle body to cooperate with said projection on said bucket as said bucket moves to the discharge position whereby said bucket is tilted to advance its lower portion further into the vehicle body, hydraulic means for actuating said shaft including, a hydraulic cylinder, a pair of pulleys mounted on the piston rod thereof, a pulley wheel mounted on the end of said shaft, and a cable fastened to the vehicle body at one end and passing around one of said pulleys, said pulley wheel, and the other of said pulleys and fastened to the vehicle body at its other end, and a hold down bar connected to said pulley wheel to be retracted in the material-diacharging position of said bucket assembly.
