Abstract: During the manufacture of bricks, either before or after such bricks are introduced to the kiln for drying, selected brick from spaced positions in at least some of the rows are mechanically displaced to corresponding positions in upstream, downstream, or otherwise adjacent rows to effect an inter-row movement of some, but fewer than all of the bricks in any particular row. According to the invention, the selected bricks may be either pushed, lifted, lowered or combinations thereof from one row and transferred to a different row. One translating device designed for this technique is a snaggle-tooth pusher which engages and pushes some, but not all of the bricks in a row or rows. The selected bricks may be initially separated from the other bricks by means of either the snaggle-tooth puller, or by means of a vertically movable support plate which operates in conjunction with a slotted support plate immediately thereabove to remove and lower selected brick.
Abstract: The invention relates to connecting members for the ends of adjacent tubs of a scraper conveyor for the use in mines in which each tub comprises two side members.The supporting partition of each connecting member has a rear face serving as a support for one of the retaining flanges and extends transversely up to the corresponding side member or up to its extension. The supporting partition is located at the rear end of the projecting portion of the male member. The width of the lateral access opening for each partition is less than the maximum dimension of the cross-section of the corresponding locating slot of the partition. The junction zones between the lateral access opening and the locating slot at the partition constitute a lateral locking means for the connecting rods relative to the partition.
