Abstract
Abstract The apparatus of this invention transfers refuse from a container into an opening at the rear end of a hopper in refuse equipment. The apparatus includes first arms pivotable to swing the lower end of the container upwardly. A member cooperates with the first arms to fixedly retain a pin on the container when the first arms have pivoted through a first particular angle. Second arms are then pivoted through a second particular angle to raise the bottom of the container above the lid of the container, while the pin on the container is held at a fixed vertical position, for providing for the transfer of the refuse from the container into the hopper. During such movement, members are moved to effectively raise the lip of the hopper upwardly and to dispose a surface for guiding the transfer of the refuse from the container into the hopper. Members are also provided for gripping the bottom of the container during the pivotal movement of the container upwardly by the second arms. The container may be provided with a detent near its bottom end to facilitate such gripping. This gripping is facilitated by disposing the fulcrum for the pivotal movement of the second arms above, and relatively close to, the fulcrum for the pivotal movement of the first arms. After the transfer of the refuse into the hopper, the second arms are pivoted downwardly through the second particular angle while the pin on the container is held fixedly in position. The first arms are thereafter pivoted downwardly through the first particular angle to return the container to an upright position on the ground.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
215 words
In combination for use with a container for holding refuse and for depositing the refuse into a hopper through an opening at the rear end of the hopper, the container having a pin and having a lid at the top of the container and also having a peripheral wall extending downwardly from the lid, first means constructed for coupling to the rear end of the hopper for engaging the peripheral wall of the container near the top of the container and for pivoting the bottom of the container upwardly about the pin on the container, second means disposed relative to the first means for cooperating with the first means to retain the pin on the container in a fixed relationship when the first means pivots the container upwardly, and third means independent in its movement of the movement of the first means and responsive only to the cooperative retention by the first and second means of the pin on the container in the fixed relationship for pivoting the container to a position where the bottom of the container is above the top of the container and is facing in a direction relative to the top of the container and the hopper to provide for the transfer of the refuse from the container into the hopper.
Claim 2
Dependent Claim
215 words
In combination for use with a container for holding refuse and for depositing the refuse into a hopper through an opening at the rear end of the hopper, the container having a pin and having a lid at the top of the container and also having a peripheral wall extending downwardly from the lid, first means constructed for coupling to the rear end of the hopper for engaging the peripheral wall of the container near the top of the container and for pivoting the bottom of the container upwardly about the pin on the container, second means disposed relative to the first means for cooperating with the first means to retain the pin on the container in a fixed relationship when the first means pivots the container upwardly, and third means independent in its movement of the movement of the first means and responsive only to the cooperative retention by the first and second means of the pin on the container in the fixed relationship for pivoting the container to a position where the bottom of the container is above the top of the container and is facing in a direction relative to the top of the container and the hopper to provide for the transfer of the refuse from the container into the hopper.
Claim 3
Dependent Claim
69 words
In a combination as set forth in claim 1 wherein the hopper has a lip defining the bottom of the opening at the rear end of the hopper, means movable with the first means to a position relative to the lip of the hopper and the top of the container for guiding the refuse into the hopper during the transfer of the refuse from the container into the hopper.
Claim 4
Dependent Claim
235 words
In combination for use with a container for holding refuse and for depositing the refuse into a hopper through an opening at the rear end of the hopper, the container having a pin and having a lid at the top of the container and also having a peripheral wall extending downwardly from the lid, a first pivot pin, first means mounted on the first pivot pin for rotary movement, the first means being constructed to engage the peripheral wall of the container at the top of the container and rotate the bottom of the container upwardly about the first pivot pin, second means disposed relative to the first means and shaped to trap the pin on the container between the first means and the second means upon the rotation of the bottom of the container upwardly by the first means about the first pivot pin and to hold the pin on the container in fixed position between the first means and the second means, a second pivot pin, and third means mounted on the second pivot pin and responsive to the fixed positioning of the pin on the container between the first means and the second means for rotating the container about the pin on the container to a position where the bottom of the container is above the lid of the container for the transfer of the refuse from the container into the hopper.
Claim 5
Dependent Claim
235 words
In combination for use with a container for holding refuse and for depositing the refuse into a hopper through an opening at the rear end of the hopper, the container having a pin and having a lid at the top of the container and also having a peripheral wall extending downwardly from the lid, a first pivot pin, first means mounted on the first pivot pin for rotary movement, the first means being constructed to engage the peripheral wall of the container at the top of the container and rotate the bottom of the container upwardly about the first pivot pin, second means disposed relative to the first means and shaped to trap the pin on the container between the first means and the second means upon the rotation of the bottom of the container upwardly by the first means about the first pivot pin and to hold the pin on the container in fixed position between the first means and the second means, a second pivot pin, and third means mounted on the second pivot pin and responsive to the fixed positioning of the pin on the container between the first means and the second means for rotating the container about the pin on the container to a position where the bottom of the container is above the lid of the container for the transfer of the refuse from the container into the hopper.
