Abstract

Abstract A mechanism to stop and then selectively discharge logs serially advanced thereto comprises crescent shaped transfer elements mounted in laterally spaced relation and cooperating to form a cradle for receiving the logs. The presence of a first log in the cradle blocks the movement of additional logs to the cradle. Mechanism to rotate the transfer elements in unison turns the cradle to discharge a log therefrom and bumper members fixed to the transfer elements block the advance of additional logs to the cradle as the first received log is discharged from the cradle.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 232 words
Apparatus of the class described comprising: conveyor means to convey loads in a first direction, said conveyor means including a shaft transverse to said first direction and over which said loads are conveyed, a cradle assembly to receive and transfer loads from said conveyor means, means supporting said cradle assembly for rotation about a first axis transverse to said first direction and spaced from said shaft, motive means operatively connected to said cradle assembly to rotate said assembly about said first axis between first and second positions, said assembly adapted to support a load received from said conveyor means in said first position and to discharge said supported load in said second position, a bumper member and means fixedly mounting said bumper member to said cradle assembly in spaced relation to said first axis, the space between said bumper member and said first axis exceeding the space between said shaft and said first axis, said mounting means defining a bight with said bumper member and said cradle assembly, said bight adapted to receive said shaft in said first position, said cradle assembly supporting said bumper member above said shaft to block the movement of loads over said shaft in said first direction when said cradle assembly is in said second position, said bumper member being moved outside the path of said loads by rotation of said cradle assembly to said first position.
Claim 2
Dependent Claim 232 words
Apparatus of the class described comprising: conveyor means to convey loads in a first direction, said conveyor means including a shaft transverse to said first direction and over which said loads are conveyed, a cradle assembly to receive and transfer loads from said conveyor means, means supporting said cradle assembly for rotation about a first axis transverse to said first direction and spaced from said shaft, motive means operatively connected to said cradle assembly to rotate said assembly about said first axis between first and second positions, said assembly adapted to support a load received from said conveyor means in said first position and to discharge said supported load in said second position, a bumper member and means fixedly mounting said bumper member to said cradle assembly in spaced relation to said first axis, the space between said bumper member and said first axis exceeding the space between said shaft and said first axis, said mounting means defining a bight with said bumper member and said cradle assembly, said bight adapted to receive said shaft in said first position, said cradle assembly supporting said bumper member above said shaft to block the movement of loads over said shaft in said first direction when said cradle assembly is in said second position, said bumper member being moved outside the path of said loads by rotation of said cradle assembly to said first position.
Claim 3
Dependent Claim 32 words
The apparatus of claim 1 including a load supporting deck over which said conveyor means moves said loads, said motive means comprising motor means connected between said deck and said cradle assembly.
Claim 4
Dependent Claim 60 words
The apparatus of claim 1 in which said cradle means comprises angularly disposed arm portions projecting radially from said first axis and web means having an arcuate margin extending between said arm portions to define a load receiving cradle, said means mounting said bumper member mounting said bumper member adjacent the radially outer end of one of said arm portions.
Claim 5
Dependent Claim 19 words
The apparatus of claim 3 in which said bumper member has a margin extending circumferentially of said first axis.
