Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A mechanism, for attachment to a refuse Vehicle having a receiver tank body, for moving refuse containers through a long arc of travel between ground level loading and elevated inverted dumping and washing positions above said refuse vehicle, said mechanism comprising a pair of vertically swingable arms having fixed pivots, refuse container supporting means interconnecting said arms, a pair of extendable and retractable power cylinder units to operate said arms in unison, fixed pivots for the cylinder ends of said units, a pair of relatively short connector links having corresponding ends pivoted to the piston rods of said units and having other corresponding ends pivoted to said arms in spaced relation to the fixed pivots of said arms, and fixed sloping straight guide rails for the pivotal connections of said links and piston rods disposed between the fixed pivots of said arms and the cylinder bodies of said units.
Claim 2
Dependent Claim
149 words
A mechanism, for attachment to a refuse Vehicle having a receiver tank body, for moving refuse containers through a long arc of travel between ground level loading and elevated inverted dumping and washing positions above said refuse vehicle, said mechanism comprising a pair of vertically swingable arms having fixed pivots, refuse container supporting means interconnecting said arms, a pair of extendable and retractable power cylinder units to operate said arms in unison, fixed pivots for the cylinder ends of said units, a pair of relatively short connector links having corresponding ends pivoted to the piston rods of said units and having other corresponding ends pivoted to said arms in spaced relation to the fixed pivots of said arms, and fixed sloping straight guide rails for the pivotal connections of said links and piston rods disposed between the fixed pivots of said arms and the cylinder bodies of said units.
Claim 3
Dependent Claim
56 words
The structure of claim 1, and said fixed guide rails comprising pairs of opposing channel bars mounted in spaced parallel relation, and pivot pins interconnecting said links and piston rods and projecting on opposite sides of said links and piston rods and having end portions engageable slidably within guide passages formed by said opposed channel bars.
Claim 4
Dependent Claim
64 words
The structure of claim 1, and said sloping guide rails having lower ends disposed near the elevation of said fixed pivots for the cylinder ends of said units and having upper ends disposed above the elevation of the last-named fixed pivots and above the fixed pivots of said arms and between the latter and the fixed pivots of said cylinder ends in triangular relationship.
Claim 5
Dependent Claim
37 words
The structure of claim 3, and the upper ends of said guide rails being relatively close to the fixed pivots of said arms and relatively distant from the fixed pivots of said cylinder ends of said units.
Claim 6
Dependent Claim
70 words
The structure of claim 2, and the spacing between the pairs of opposing channel bars being sufficient to allow passage therebetween of said arms and said connector links when the arms move between their lowered and raised working positions, said arms and said links lying substantially on the parallel axes of said power cylinder units and said channel bars spaced apart symmetrically with respect to the axes of said units.
Claim 7
Dependent Claim
23 words
The structure of claim 5, and relatively stationary support members for the fixed pivots of said arms and said pairs of channel bars.
Claim 8
Dependent Claim
19 words
The structure of claim 6, and rigid bracket means interconnecting the pairs of channel bars and said support members.
Claim 9
Dependent Claim
56 words
The structure of claim 1, and pairs of spaced upstanding gusset plates on said arms near said fixed pivots of the arms, and corresponding ends of said connector links pivotally connected to said gusset plates, said links adapted to swing between said gusset plates during movements of said arms under influence of said power cylinder units.
