Abstract
Abstract In a load stacker, a load is moved vertically while resting on an elevating platform, and is adapted to be moved lateraly from the platform into a storage bin at one side or the other of the platform, and also to be moved from bins at each side of the platform, back onto the platform. A shuttle moves relatively to the elevating platform in either of opposed directions and through this movement, is adapted to move a load into or out of a bin at each side of the platform. For contacting the load, the shuttle carries a novel form of pusher utilizing a pair of chains between which bars are mounted, the bars being secured at their opposed ends to the chains. Through movement of the chains, the bars may be applied to one end of the load or to another end of the load, and when so applied to an end of the load, the movement of the shuttle effects movement of the load in the direction that may be required. As a part of the platform, a bridge is utilized for facilitating movement of the load onto the platform and off the platform.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
In a load stacker, load mainpulating means for moving a load in either of opposed directions, said load manipulating means comprising pusher means mounted for selective engagement with either of opposed surfaces of said load, means mounting said load mainpulating means for movement in a path toward and away from said load, means for moving said load manipulating means bodily in said path with said load in either of said opposed directions with said pusher means applied to one of said opposed surfaces so as to move the load therewith, and means for moving said pusher means into a vertical position at one end surface or the other of said load for engagement with said one end surface or the other.
Claim 2
Dependent Claim
121 words
In a load stacker, load mainpulating means for moving a load in either of opposed directions, said load manipulating means comprising pusher means mounted for selective engagement with either of opposed surfaces of said load, means mounting said load mainpulating means for movement in a path toward and away from said load, means for moving said load manipulating means bodily in said path with said load in either of said opposed directions with said pusher means applied to one of said opposed surfaces so as to move the load therewith, and means for moving said pusher means into a vertical position at one end surface or the other of said load for engagement with said one end surface or the other.
Claim 3
Dependent Claim
33 words
In the combination of claim 1, the feature that said load stacker includes a load supporting platform, and means fixed to said platform mounting said load manipulating means for moveMent in said path.
Claim 4
Dependent Claim
46 words
In the combination of claim 1, the feature that said pusher means are mounted on a shuttle constituting part of said load manipulating means, and means to impart reciprocating movement to said shuttle in said path to move said pusher means therewith also in said path.
Claim 5
Dependent Claim
50 words
In the combination of claim 3, the feature that a load platform is fixed relatively to the mounting means for said shuttle for supporting a load relatively to which said pusher means is moved to position the pusher means at one or the other of opposed ends of said shuttle.
Claim 6
Dependent Claim
102 words
In the combination of claim 4, the feature that said pusher means is a pair of spaced flexible members such as a pair of chains, a series of bars extending between said flexible members and secured thereto at spaced points for movement therewith, a vertical mounting device at each side of said shuttle, guide sprockets or the like on each device for guiding said flexible members for movement in parallel paths whereby movement of said flexible members in said paths will place said bars at one end surface or the other of a load resting between said mounting devices of said shuttle.
Claim 7
Dependent Claim
62 words
In the combination of claim 5, the feature that said means mounting said load manipulating means for movement in a path are means mounting said shuttle for reciprocating movement to each side of a central position in a fixed path, and a load platform fixed to said mounting means for said shuttle for supporting a load to be moved by said shuttle.
Claim 8
Dependent Claim
35 words
In the combination of claim 5, the feature that said mounting devices at each side of said shuttle are spaced a sufficient distance to permit a load to be positioned therebetween on said load platform.
Claim 9
Dependent Claim
40 words
In the combination of claim 1, the feature that said pusher means is a flexible member, a series of bars secured to said flexible member for movement therewith, and means guiding said flexible member for movement into said vertical position.
Claim 10
Dependent Claim
52 words
In the combination of claim 1, the feature that said pusher means is a pair of spaced flexible members such as a pair of chains, a series of bars extending between said flexible members and secured thereto at spaced points for movement therewith, and means guiding said flexible members in parallel paths.
