Abstract
Abstract Dumping apparatus is illustrated wherein a novel compound linkage system is employed in which a first link is pivoted to move a receptacle and the like as to be dumped to an intermediate position and thereafter through movement of a second link the receptacle is raised to dumping position, but only after a latch mechanism to positively position the receptacle is secured through a novel lost motion coupling.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
152 words
Receptable dumping apparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried for pivotal movement by said support having extensible means; a first link having pivotal connection adjacent one end on said support for raising said carriage; a second link pivotally connected to said first link adjacent one end and being pivotally connected for raising said carriage and the receptacle carried thereby on the other end; said first and second links being pivotally connected to said extensible means; and said first link and said second link being movable by said extensible means sequentially by said cylinder wherein said second link is raised following pivoted movement of said first link to an intermediate position positioning said carriage in position preparatory to dumping a receptacle carried thereby.
Claim 2
Dependent Claim
152 words
Receptable dumping apparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried for pivotal movement by said support having extensible means; a first link having pivotal connection adjacent one end on said support for raising said carriage; a second link pivotally connected to said first link adjacent one end and being pivotally connected for raising said carriage and the receptacle carried thereby on the other end; said first and second links being pivotally connected to said extensible means; and said first link and said second link being movable by said extensible means sequentially by said cylinder wherein said second link is raised following pivoted movement of said first link to an intermediate position positioning said carriage in position preparatory to dumping a receptacle carried thereby.
Claim 3
Dependent Claim
24 words
The structure set forth in claim 1 including a latch slidable on said carriage for securing said receptacle responsive to raising said second link.
Claim 4
Dependent Claim
19 words
The structure set forth in claim 2 including a lost motion coupling connecting said second link and said latch.
Claim 5
Dependent Claim
25 words
The structure set forth in claim 1 including a stop member carried by said support limiting pivotal movement of said cylinder at said intermediate position.
Claim 6
Dependent Claim
36 words
The structure set forth in claim 1 wherein said second link is pivoted on the inside of a line passing through the pivot point of said cylinder and a remote pivot point of said second link.
Claim 7
Dependent Claim
105 words
Receptable dumping aparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried by said support having extensible means; linkage means connected to said extensible means for raising said carriage and the receptacle carried thereby responsive to movement of said extensible means; a latch slidable on said carriage for securing said receptacle upon said carriage responsive to said linkage means; and a lost motion coupling connecting said linkage means to said latch and for raising said carriage for dumping.
Claim 8
Dependent Claim
105 words
Receptable dumping aparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried by said support having extensible means; linkage means connected to said extensible means for raising said carriage and the receptacle carried thereby responsive to movement of said extensible means; a latch slidable on said carriage for securing said receptacle upon said carriage responsive to said linkage means; and a lost motion coupling connecting said linkage means to said latch and for raising said carriage for dumping.
Claim 9
Dependent Claim
42 words
The structure set forth in claim 6, wherein said lost motion coupling includes a pair of links pivotally connected in end-to-end relation between said carriage and said latch, and a block sliding on said pair of links connected to said linkage means.
Claim 10
Dependent Claim
174 words
Receptacle dumping apparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried for pivotal movement by said support having extensible means; a first link having pivotal connection adjacent one end on said support; a second link pivotally connected to said first link adjacent one end and being pivotally connected for raising said carriage and the receptacle carried thereby on the other end; said first and second links being pivotally connected to said extensible means; and an intermediate arcuate bearing member carried by said first link; a pin carried by said support engagable by said arcuate bearing member; and said links being movable by said extensible means sequentially by said cylinder wherein said second link is raised following pivoted movement of said first link to an intermediate position whereupon said arcuate bearing member leaves said pin positioning said carriage in position preparatory to dumping a receptable carried thereby.
Claim 11
Dependent Claim
174 words
Receptacle dumping apparatus attachable to a refuse truck and the like comprising: an upright mounting support attachable to said truck; a carriage for carrying a receptacle for dumping into said truck pivotally carried by said support; a cylinder carried for pivotal movement by said support having extensible means; a first link having pivotal connection adjacent one end on said support; a second link pivotally connected to said first link adjacent one end and being pivotally connected for raising said carriage and the receptacle carried thereby on the other end; said first and second links being pivotally connected to said extensible means; and an intermediate arcuate bearing member carried by said first link; a pin carried by said support engagable by said arcuate bearing member; and said links being movable by said extensible means sequentially by said cylinder wherein said second link is raised following pivoted movement of said first link to an intermediate position whereupon said arcuate bearing member leaves said pin positioning said carriage in position preparatory to dumping a receptable carried thereby.
Claim 12
Dependent Claim
53 words
The structure set forth in claim 8 including a latch slidable on said carriage for securing said receptacle responsive to raising said second link, a stop member carried by said support limiting pivotal movement of said cylinder at said intermediate position, and a lost motion coupling connecting said second link and said latch.
Claim 13
Dependent Claim
36 words
The structure set forth in claim 1 wherein said second link is pivoted on the inside of a line passing through the pivot point of said cylinder and a remote pivot point of said second link.
