V the bags of material as they are unloaded from When the hoists arrive above the end of the 55 the hold of the vessel; and conveyer 50, the load of sugar bags is lowered 55 upon the end of conveyer 50, where an operator is stationed to release said bags from the hoist. The sugar bags are received upon this conveyer 50 without regard to distribution thereof and in superimposed relation. When the bags reach the inclined section 53 of conveyer 50, the upper bags fall downwardly thereon over the lower bags which are in direct contact with the conveyer and are guided by the'chute section 54 to the high speed conveyer 55. Therefore, owing to the relatively high speed of travel of the latter 'su'hheavy bags of sugar or other material may be expeditiously handled, weighed and transported to a predetermined destination. The several operations may be carried out with absolute safety, both to the apparatus and to the'necessary attendants "in charge thereof, and the manual labor which has heretofore been incident to the handling of such materials to be reduced to a minimum.

In the foregoing description of the accompanying drawing, I have disclosed one embodiment of the essential features of my present invention, which I believe to be entirely practical for the purpose in view. It is nevertheless to be understood that my invention is capable of embodiment in many difierent environments and may. also be incorporated in various other alternative structural forms, and I accordingly reserve the privilege. of resorting to all such legitimate changes in the form, construction and relative arrangement of the several parts as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim:- 1. In a conveying and distributing apparatus for superposed bags of sugar or the like, two

unconnected and separately organized conveyers,

one comprising a bag-receiving conveyer and the other a bag-discharging conveyer, the former receiving the bags in superposed arrangement from a source of supply and being located in a plane higher than the plane of the latter and having as a, component part thereof a rear end conveying portion inclined downwardly at a sharp angle from the main body of the conveyer and toward the surface of the discharging conveyer, means for operating the receiving conveyer at relatively low speed, means for simultaneously operating the discharging conveyer at relatively high speed, and downwardly inclined stationary means established between said rear end portion and the surface of the discharging conveyer, said means constituting a continuation of said rear end portion and being in surface alignment therewith for receiving bags therefrom and having an overall length sufiicient to provide time in which all of the received bags will by reason of their descending force and weight assemble thereon in direct contact therewith in single row order for discharge one behind the other from the stationary means on which they are so assembled, directly onto the surface of the discharging conveyer, said downwardly inclined rear end conveying portion being effective to give superimposed bags a definitely controlled downward momentum for casting them 01? balance and into proper place in the single line order.

2. In a conveying and distributing apparatus for bags of sugar or the like, the combination of a high-speed conveyer and a separate low-speed conveyer, the latter disposed to convey in the direction of its length in a plane higher than the plane of the high-speed conveyer and having as component parts thereof a horizontal portion and a rear end portion inclined downwardly at a sharp angle from the horizontal portion and toward the surface of the hi h-speed conveyer, a separate slideway device interposed downwardly between said rear end portion and the surface of said high speed conveyer with its surface in alignment with the surface of said rear end portion and with its opposite ends in clearance relation to said respective parts, said low speed conveyer having capacity to convey bags in supcrpose row arrangement and its rear end portion being effective through its sharp downwardly inclined operation to cause definite separation and dislodgment of the superimposed bags so as to enable them to settle into proper alternating positions with the bags in the single row, and said slideway device having an overall course sufiicient in extent to permit the settling bags to come in direct contact with said device so that all of the bags will slide in single row arrangement upon the sliding surface of the said device prior to their successive discharge thereby upon the surface of the high-speed conveyer.
