Stationary refuse packer

Claim 2

In a refuse packer wherein a ram is slidably mounted in a housing for controlled reciprocation between a packing position and a loading position, the combination with said packer of a ram actuator including A. a power source mounted on said housing; B. a feed screw mounted for rotation substantially centrally longitudinally in the ram and having a sliding telescopic supporting connection at one end with the ram and adapted at its opposite end to be rotated by the power source; C. a ball nut having a driven connection with the feed screw for movement along the screw as the screw is rotated; and D. means connecting the ball nut to the ram.

Claim 3

A refuse packer as claimed in claim 1, wherein the power source is actuated automatically when a predetermined quantity of refuse is located in the housing and wherein there is included controlling and limiting means to limiT reciprocation of the ram within the housing.

Claim 4

The refuse packer as claimed in claim 1, wherein the ram includes means to restrict passage of refuse to the housing when the ram is moving and whereby the reciprocation of refuse into the housing is always forward of the ram.

Claim 5

The refuse packer as claimed in claim 1, wherein the power source includes an electric motor which is connected operatively to the ball nut and feed screw mechanism through V belts and pulleys.

Claim 6

The refuse packer as claimed in claim 1 wherein the ram is provided with material having a low coefficient of friction, such material being located between the ram and the housing.

Claim 7

In a refuse packer wherein a ram is slidably mounted in a housing for controlled reciprocation between a packing position and the loading position, the combination with said packer of a ram actuator including A. a power source mounted on said housing; B. a feed screw mounted for rotation substantially centrally longitudinally in the ram to project at one end outside the ram and being supported at its projecting end in a self-aligning bearing as well as being adapted at such end for rotation by the power source; C. a ball nut having a driven connection with the feed screw for movement along the feed screw as the screw is rotated; and means including a gimbal mounting for connecting the ball nut to the ram.

Claim 8

In a refuse packer wherein a ram is slidably mounted in a housing for controlled reciprocation between a packing position and the loading position, the combination with said packer of a ram actuator including A. a power source mounted on said housing; B. a feed screw mounted for rotation substantially centrally longitudinally in the ram to project at one end outside the ram and being supported at its projecting end in a self-aligning bearing as well as being adapted at such end for rotation by the power source; C. a ball nut having a driven connection with the feed screw for movement along the feed screw as the screw is rotated; and means including a gimbal mounting for connecting the ball nut to the ram.

Claim 9

The refuse packer as claimed in claim 6 wherein the ram is provided with material having a low coefficient of friction, such material being located between the ram and the housing.
