Abstract
A trash dumping apparatus adapted to be mounted on a trash pick-up truck alongside the open-top, trash-receiving body thereof operative automatically by unique mechano-hydraulic means to pick-up trash containers and to dump the contents thereof in the body, the mechano-hydraulic means being strong and rugged in construction, durable and relatively trouble free in use to minimize maintenance cost and consequential down time of the vehicle otherwise necessary for servicing and repair of the equipment.
Claims9
A trash pick-up and dumping apparatus adapted for mounting on a vehicle having an open-top, trash-receiving body, said apparatus comprising
- support means adapted to be mounted on said vehicle alongside the trash receiving body thereof;
- lift frame means connected to said support means by first horizontal pivot means normally dependent from and swingable vertically from the latter;
- rocker frame means connected to said lift frame means below said first pivot means by second horizontal pivot means, said rocker frame means being movable bodily with said lift frame means and also independently rockable about a horizontal axis defined by said second pivot means;
- first power actuator means operatively connected to said lift frame means to swing the same and said rocker frame means vertically about said first pivot means;
- trash-container-engaging-means carried by said rocker frame means in front of said lift frame means and said support means;
- and
- lever means interacting between said support means and said rocker frame means actuated automatically by vertical swinging movement of said lift frame means to rock said rocker frame means on said second pivot means first in one direction to hold said rocker frame means and said trash-container-engaging means generally horizontal and a trash container carried by the latter in generally upright orientation during a first portion of upward swinging movement of said lift frame means and to rock said rocker frame means in the opposite direction about said second pivot means during a subsequent portion of the upward swinging movement of said lift frame means to flip said trash container upside down behind said support means;
- said first power actuator means including a crank arm means pivotally connected at one end thereof to said lift frame means adjacent to said first horizontal pivot means;
- and
- means forming a part of said lift frame means below and supporting said crank arm means intermediate said first horizontal pivot means and the pivot connection between said crank arm means and said lift frame means during at least a portion of the vertical swinging movement of said lift frame means.

- said lift frame means normally depending from said first pivot means and being swingable upwardly through an arc of substantially 180.degree.;
- said first power actuator means being pivotally connected to said support means and including
- a reciprocally driven member;
- and
- at least one crank arm means pivotally connected to said reciprocally driven member and to said lift frame means adjacent to and below said first pivot means;
- and
- wherein said lift frame means includes
- means forming an abutment below said crank arm means engageable by the latter during at least a portion of its pivotal movement during reciprocation of said first power actuator means in a direction to swing said lift frame means upwardly from its normally dependent position.
