This invention relates to improvements in belt conveyers, and more particularly to improvements in a sectional belt conveyer of the fiat belt type adapted for use in mines.

My invention may be more clearly understood with reference to the accompanying drawing wherein:

Figure 1 is a fragmentary plan view of a secprevent damage to the under side and edges of the belt as said belt passes from one section to the other and to permit said members to be pivotally adjusted with respect to each other (see Figures 2 and 4). 1

It should herein be noted that a gap is provided between the ends of the spacing members H, H in order to permit adjustment of the conveyer to an uneven bottom and that material tends to fall through this gap onto the lower run of the belt which causes wear of the belt and clogging of the idler pulley.

With reference now in particular to the details of the novel form of supporting standards embodying my invention, each of said standards includes the parallel spaced upstanding sides l5, l which rest on the ground and are connected together in spaced relation with respect to each other by a pair of spaced apart transversely. extending connecting members 2!, 21. Each of i said upstanding sides has a pair of spaced apart

legs

22, 22 with horizontally extending

portions

23, 23 extending away from the conveyer to form supporting feet adapted to rest on the ground. A bracket 24 extends from one of said legs, into the space between said legs, and said brackets on opposite upstanding sides I5, I 5 form a support for the ends of the shaft for the roller [4. An intermediate portion 25 of each of said upstanding sides is beveled upwardly and inwardly toward the belt so the lower portion of said standards will be wider than the upper portion thereof to prevent rubbing of the edges of the lower run of the belt on said standards. An opening 26 is provided in the upright portion of each of said upstanding sides immediately above said beveled intermediate portion. As herein shown, said opening is formed by stamping out the upright upper portion of said side and bending the stamped portion inwardly. Said stamped portion extends inwardly of said side in an angularly upward direction and is preferably at the same angle as said inclined portion so itmay form a collecting chute 21 which covers the lower run of the belt at the joint between said spacing members to collect material which spills through said joint and permit it to be discharged through said opening away from the belt. Said collecting chute has an upright upper end 28 which is notched so as to open toward the upper end thereof to receive an end of the shaft for the upper belt supporting roller I2.

It may thus be seen that a sectional conveyer of the flat belt type has been provided which may readily conform to an uneven bottom and which is so arranged as to prevent spillage of material onto the lower run of the belt, and that said conveyer includes a standard of a novel and simplified form of construction, so arranged as to cover the lower run of the belt at the point of junction of the spill plates so that material which may fall through the gap between said sections may be collected and discharged beyond said standard. It may also be seen that this collecting means comprises an inwardly extending chute on each side of each standard which is herein shown as being an integral portion of said standard and which also forms a means for supporting the roller for the upper run of the belt.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be construed as limiting myself to the specific embodiment illustrated, excepting as it may be limited in the appended claims.
