Container lift and dump apparatus

Claim 2

A container lift and dump apparatus, comprising in combination a support, a horizontal fulcrum provided on said support, an elongated frame mounted by one end thereof on said fulcrum for vertical swinging movement between a lowered position wherein the frame extends downwardly from the fulcrum and a raised position wherein it slants upwardly and outwardly from the fulcrum, drive sprocket means coaxial with the fulcrum, idler sprocket means provided on said frame remote from the fulcrum, endless chain means passing around said drive sprocket means and said idler sprocket means, container engaging means provided on said chain means and disposed adjacent said idler sprocket means when said frame is in its lowered position, fixed abutment means provided on said frame adjacent said drive sprocket means but spaced radially from said fulcrum, and means for driving said drive sprocket means whereby said container engaging means may first be lifted by said chain means to an elevated position against said abutment means while said frame is relatively stationary, and whereby continued rotation of the drivE sprocket means may then swing the frame with the chain means to the raised position of the frame in which a container supported by said container engaging means is dumped.

Claim 3

The apparatus as defined in claim 1 together with a driving lug provided on said drive sprocket means in radially spaced relation from said fulcrum, and a fixed lug provided on said frame, said driving lug being engageable with said fixed lug when said container engaging means is in its elevated position, whereby to assist in swinging the frame to its raised position.

Claim 4

The apparatus as defined in claim 1 together with resilient means reacting between said support and said frame to assist in returning the frame from its raised to its lowered position.

Claim 5

The apparatus as defined in claim 1 together with a rest provided on said support for said frame in its lowered position.

Claim 6

The apparatus as defined in claim 1 together with a container rest provided on said frame at a point spaced longitudinally from said container engaging means.

Claim 7

The apparatus as defined in claim 1 wherein said container engaging means include upturned hook means adapted to engage a fixed bail at one side of a container.

Claim 8

The apparatus as defined in claim 1 wherein said abutment means include downturned hook means adapted to engage a fixed bail at one side of a container.

Claim 9

The apparatus as defined in claim 1 which is further characterized in that said container engaging means and said abutment means cooperate through the medium of a fixed bail provided at one side of a container.

Claim 10

The apparatus as defined in claim 1 together with a drive motor mounted on said support and having a drive shaft which constitutes said fulcrum, said drive sprocket means being secured to said drive shaft for rotation therewith and said frame being swingably mounted on the drive shaft.

Claim 11

The combination of a container, a receptacle for contents of said container, and apparatus whereby the container may be lifted and its contents dumped into said receptacle, said apparatus comprising a horizontal fulcrum provided on the outside of said receptacle, an elongated frame mounted by one end thereof on said fulcrum for swinging movement between a lowered position wherein the frame extends downwardly from the fulcrum and a raised position wherein it slants upwardly and outwardly from the fulcrum, drive sprocket means coaxial with the fulcrum, idler sprocket means provided on said frame remote from the fulcrum, endless chain means passing around said drive sprocket means and said idler sprocket means, means provided on said chain means for engaging said container, said container engaging means being disposed adjacent said idler sprocket means when said frame is in its lowered position, fixed abutment means provided on said frame adjacent said drive sprocket means but spaced radially from said fulcrum, and means for driving said drive sprocket means whereby said container engaging means may first lift said container to an elevated position in which the container engaging means come into abutment with said abutment means while said frame is relatively stationary, and whereby continued rotation of the drive sprocket means may then swing the frame with said container to the raised position of the frame in which the contents of the container are dumped into said receptacle.

Claim 12

The combination of a container, a receptacle for contents of said container, and apparatus whereby the container may be lifted and its contents dumped into said receptacle, said apparatus comprising a horizontal fulcrum provided on the outside of said receptacle, an elongated frame mounted by one end thereof on said fulcrum for swinging movement between a lowered position wherein the frame extends downwardly from the fulcrum and a raised position wherein it slants upwardly and outwardly from the fulcrum, drive sprocket means coaxial with the fulcrum, idler sprocket means provided on said frame remote from the fulcrum, endless chain means passing around said drive sprocket means and said idler sprocket means, means provided on said chain means for engaging said container, said container engaging means being disposed adjacent said idler sprocket means when said frame is in its lowered position, fixed abutment means provided on said frame adjacent said drive sprocket means but spaced radially from said fulcrum, and means for driving said drive sprocket means whereby said container engaging means may first lift said container to an elevated position in which the container engaging means come into abutment with said abutment means while said frame is relatively stationary, and whereby continued rotation of the drive sprocket means may then swing the frame with said container to the raised position of the frame in which the contents of the container are dumped into said receptacle.

Claim 13

The combination as defined in claim 10 wherein said container includes a fixed bail at one side thereof, said container engaging means including upturned hook means engageable with said bail.

Claim 14

The combination as defined in claim 10 wherein said container includes a fixed bail at one side thereof, said container engaging means being engageable with said bail and acting through the medium of the bail to abut said abutment means.
