Abstract: A cartoner for elongated articles including a source of a series of unshaped bundles thereof, a first conveyor having first article buckets thereon with a first reach adjacent to the source of articles so that each first article bucket receives an unshaped bundle of articles therein, a second conveyor having a set of second article buckets each having at least one wall shiftable between receiving and shaping positions with a first reach of the second conveyor adjacent to the first reach of the first conveyor so that each of the second article buckets receive an unshaped bundle of articles from one of the first article buckets, a leveling plate for leveling the contents of the second article bucket with the wall in the shaping position thereof, a set of filler members on the second conveyor for pushing the elongated articles from the second article bucket into a carton on an adjacent carton conveyor, and suitable control mechanism for causing the proper interaction of the various conveyors and parts thereof.

Abstract: The disclosure relates to bucket elevators of the type having a series of rotatably mounted buckets carried by and extending between spaced apart, parallel traction chains or belts. The traction chains or belts are, at the discharge station, disposed to run up over guide rollers, the cam surface of the discharge station consisting of a circular cam surface concentric with the guide rollers, and the cam follower surface of each bucket consisting of a corresponding arcuate cam follower surface, in order that the buckets abut with their arcuate cam follower surface against the circular cam surface of the guide rollers during the passage of the traction chains or belts over the guide rollers of the discharge station.

Abstract: Gravity type carrier mechanism for baking pans and the like comprising a chain conveyor system and stationary and rotary cams suitable to produce one hundred and eighty degree pan turnover. The pans comprise individual gravity suspension systems wherein pan suspension pins are arranged to travel within vertically oriented slots in the pans whereby the center of gravity of each pan is automatically varied during turnover by interaction of the stationary and rotary cams upon the pins as the conveyor transports the pans.

Abstract: Apparatus is disclosed for positioning fruit of the drupe type in which the fruit is conveyed along a vertically elongated path from a receiving station upward along the path and then downward along the path to a discharge station with the positioning apparatus being operative to urge the fruit to a predetermined orientation during both the upward and downward portions of travel from the receiving station to the discharge station.

Abstract: An apparatus for proofing lumps of dough has an endless conveyor. A series of first cups are mounted on one side of the conveyor for transporting lumps of dough and series of second cups are mounted on the opposite side of the conveyor of transporting lumps of dough. The second cups are spaced from the first cups, and the first and second cups have the conveyor disposed therebetween. Also, the first and second cups are staggered relative to each other so that the distance between each first cup and an adjacent second cup is equal to the distance between that second cup and the next first cup along the conveyor. Lumps of dough are loaded into the first and second cups and, after having been transported, are discharged from the first and second cups. The endless conveyor and the first and second cups are contained in an enclosure in which a proofing environment for the lumps of dough is provided.

Abstract: A pump for concrete or other moist flowable material containing aggregate, including a hopper, a pair of alternately stroking pump assemblies below the hopper for forcing concrete via a junction valve into a common output line, and a loading system for alternately charging the two pump assemblies with concrete from the hopper. The loading system includes a conveyor and a pair of generally vertical charging chambers having lower outlet ports communicating with inlet openings in the respective pump assemblies, and upper portions extending into the hopper through the lower hopper wall and terminating upwardly in open tops disposed above the highest possible level of concrete in the hopper.

Abstract: A reversible arrangement for transporting bulk materials includes a plurality of buckets mounted on a bucket wheel for rotation therewith and for pivoting between respective end positions in which the open ends of the buckets face in respective circumferential directions of the bucket wheel. The buckets are mounted on levers which are interconnected by flexible elements for coordinated displacement of the buckets between the end positions. The bucket wheel carries two circumferentially and radially spaced cams which control the extent of displacement of cam followers of respective switches between their respective retracted and extended positions. A detaining arrangement is situated along the path of movement of the buckets and engages one of the buckets during the reverse motion of the bucket wheel to detain the bucket while the bucket wheel continues to rotate so that the buckets are angularly displaced between their end positions.

Abstract: A muck-evacuating system such as for use in tunneling operation and including in combination a train of wagons running in a tunnel and an elevator of separate receptacles adapted to automatically pick up the muck-filled receptacles one by one off the train of wagons, to raise them through a shaft to automatically trip them over to discharge the muck therefrom into a chute at ground level, and to return the emptied receptacles on the wagons, which are then moved through the tunnel for refilling at the tunnel face.

Abstract: A conveyor system for harvesting machines comprising a plurality of pivotally supported buckets of relatively rigid and nonporous material such as metal or plastic adapted to be moved through an endless path. The path includes spaced horizontal and vertical portions each defined by spaced and parallel rails fixed to the machine frame. Each bucket is supported in a crop-carrying position by an element at each end thereof having a rod portion rotatably connected to the bucket and having a bearing roller mounted thereon for engaging the rails. The supporting elements include a leg portion engaging the bucket at a location spaced from the pivotal connection of the rod portion for limiting pivotal movement of the bucket along a portion of the conveyor path. Each bucket is pivoted to a position for discharging crops along other portions of the path by means on the bucket which engages a rail in a manner pivoting the bucket about the supporting rod portion.
