A refuse carrier is described of the type consisting of a motor vehicle having a compartment adapted to receive and compact refuse. The novel feature relates to a loading and compacting mechanism comprising a pusher-blade extending across a lower portion of the compartment with a telescopic hydraulic cylinder for moving the pusher-blade horizontally backward and forward between a refuse-receiving position and refuse-compacting position. A bucket is pivotally mounted along the upper edge of the blade for pivotal movement between a lower refuse-receiving position and an upper refuse-discharging position. One or more cam wheels is articulated between the bucket and the blade by means of pivotal arms and a cam guideway forms an incline path between a lower refuse-receiving position and an upper refuse-discharging and compacting position. The cam wheel in response to movement of the pusher-blade in a compacting direction travels up the guideway, thereby forcing the bucket to swing from a lower horizontal refuse-receiving position to an upper vertical refuse-discharging position, with the bucket in the vertical position acting as a vertical extension of the compacting blade during continued movement of the blade in compacting direction. With the bucket in this vertical position, it can also serve as a pusher for emptying all of the refuse from the container.
In a self-loading refuse carrier, the combination with a motor vehicle having a compartment adapted to receive and compact refuse therein, of a loading and compacting mechanism comprising:
A refuse vehicle comprising a motor vehicle having a cab and a refuse carrying body, said body being enclosed by side walls, a front wall, a top wall and an openable rear door, refuse-receiving openings in said side walls adjacent the forward ends thereof, a loading and compacting mechanism mounted within said body adjacent said refuse-receiving openings, said mechanism including a pusher-blade extending across a lower portion of the body between the sidewalls thereof, a single telescopic hydraulic cylinder mounted centrally in said vehicle forward of the pusher-blade for moving said pusher-blade horizontally backward and forward between a refuse-receiving position and a refuse-compacting position, a bucket pivotally mounted along the upper edge of said blade for pivotal movement between a lower refuse-receiving position adjacent said side wall refuse-receiving openings and an upper refuse-discharging position, said bucket including a high central hump portion extending over the hydraulic cylinder and vehicle frame, which hump portion forms a pair of laterally spaced refuse-receiving pockets, a pair of laterally spaced cam wheels articulated by pivotal arms between the bucket and blade and a pair of cam guideways in the form of inclined ramps mounted laterally adjacent the sides of the vehicle frame whereby said cam wheels in response to movement of said pusher-blade in a compacting direction travel up said ramps, thereby forcing said bucket to swing from a lower horizontal refuse-receiving position to an upper vertical refuse-discharging position, said bucket in vertical position acting as a vertical extension of the compacting blade with continued movement of the blade in compacting direction.
