CONVEYER OF THE BELT TYPE.

Application filed January 14. 1928, Serial No 246,778, and in Great Britain January 18, 1927.

This invention, which refers to conveyors of the belt type, relates to a supporting structure for rollers for the belting to travel on, to a shelter for the lower run of the belting, and to construction and arrangement of the members generally.

According to this invention a supporting structure comprises longitudinal units of inverted trough formation. each unit having a roofing and dowinvardly extending sides, connection means, for connecting together units of the structure arranged end to end with an intervening space between adjacent ends, the connect-ion means comprising a roofing over the intervenin space, and pedestals at the ends of the units for supporting the structure.

The connection of two units end to end may be made partly by a plate arranged to extend from the roo g of one unit to the roofing of the'adjacent unit and form a roofing over the intervening space, and partly by carriers extending across the intervening space between the adjacent ends of the two units, a

- carrier at each side. Mountings for rollers for the upper run of the belting are provided on the units and mountings for rollers for the lower run of the belting are provided on the carriers. With a supporting structure of this description the upper run of the belting is situated above the roofin and the lower run of the belting is situated below the roofing, and protection for the lower run of the belting at the sides is provided by the downwardly extending sides of the units, eX- cept at the positions where the lower rollers are mounted. At those positions roofing protection is provided, and the under rollers are visible and accessible from the sides. The downwardly extending sides of a unit and the position of the under rollers may be such that the lower edges of the downwardly extending sides are as low or lower than the underside of the under rollers.

For supporting the units at adjacent ends on each side pedestals may be formed as separate parts or a carrier may be formed to comprise pedestals. For example, in one arrangement the pedestals provided comprise two pedestals at each end of a unit, each unit thus having four pedestals, and, at each side, on two adjacent pedestals a carrier is mounted. In another case, two carriers, one at each side, extend downwardly to act as pedestals, thus, a carrier and pedestals for one side cross sectional views, the sections being at 2 and 3 of Figure 1 respectively, illustrating one construction.

Figure 4 is a side elevation showing portions of two units, and Figures 5 and 6 are cross sectional views, the sections being at 5 and 6 of Figure 4 respectively, illustrating another construction.

The drawings show. Units A of inverted trough formation. each unit having a roofing 7 and downwardly extending sides 8. Plate B roofing over the intervenin space between adjacent ends of units A. arriers C extending across the intervening space. Mountings 9 for rollers D. Mountings 10 for roller E. Rollers D are for the upper run and roller E for the lower run of the belting F. Straps 11 for the mountings 9 and transverse ties 12.

In the example as illustrated in Figures 1 and 2 the units A and carriers C are supported on pedestals 13.

In the example as illustrated in Figures 4 and 5 each carrier C extends downwardly at 14 and forms a pedestal on which the units A are supported.

I claim 1. A supporting structure for rollers of a conveyor of the belt type, comprising longitudinal units of inverted trough formation, each unit having a roofing and downwardly extending sides, connection means for connecting units arranged end to end with an intervening space between their adjacent ends, said connection means comprising a roofing extending longitudinally over'the intervening space, carriers extending longitudinally across said intervening space, one carrier at each side, said carriers being at a distance below the level of the roofing, mountings on the longitudinal units for rollers for the upper run of the belting, mountings on the carriers for rollers for the lower run of the belting, the upper run being above the roofing the lower run being below the roofing, and pedestal supports at the ends pf tliile longitudinal units, for the purposes set ort 2. A supporting structure for rollers of a conveyer of the belt type, comprising longitudinal units of inverted trou h formation, each unit having a roofing an downwardly extending sides, units of the structure being arranged end to end with a space intervening between their adjacent ends, a plate roofing over the intervening space, carriers extending longitudinally across said intervenin space fora roller for the lower run of the elting, one carrier at each side, mountings on the longitudinal units for rollers for the upper run of the belting, the upper run of the belt in being above the roofing the lower run being below the roofing, and pedestal suports at the ends of the longitudinal units, or the purposes set forth.

3. A supporting structure for rollers of a conveyer of the belt type, comprising longitudinal units of inverted trough formation, each unit having a roofing and downwardly extending sides, connection means for connecting units arranged end to end with an intervening space between their adjacent ends, said connection means comprising a roofing extending longitudinally over the intervening space, carriers extending longitudinally across said intervening space for a roller for the lower run of the beltin one carrier at each side, mountings on t e longitudinal units for rollers for the upper run of the belting, the upper run being above the roofin the lower run being below the roofing, and pedestal supports formed as integral arts with the carriers, for the purposes set orth. 4. A supporting structure for rollers of a conveyer o the belt type, comprising longitudinal units of inverted trough formation, each unit having a roofing and downwardly extending sides, units of the structurebeing arranged end to end with an intervening space between their adjacent ends, a plate roofing over the intervening space, carriers extending longitudinally across said intervening space, one carrier at each side, said carriers eing at a distance below the level of the roofing, mountings'on the lon itudinal units for rollers for the upper run 0 the belting, mountings on the carriers for rollers for the lower run of the belting, the upper run being above the roofing the lower run being below the roofing, and pedestal supports supports formed as downwardly extending arts of the carrier, for the purposes set orth.
