Definitions

  • This invention relates to conveyers of the kind employing endless travelling belts; It has already been proposed in such conveyers to provide a pair of anti-spillage shelves running in the direction of the length of the conveyer below the two edges of the belt, the belt resting on the said shelves when loaded, or on material gatheredthereon.
  • Figure 1 illustrates a general view of a conveyer according to the present invention
  • Figure 2 represents a side view
  • Figure 3 a plan of a preferredform
  • Figure 4 is a side sectional view. of Figure 2 taken on the line 1v 1v,
  • FIG. 5 is a perspective v1ew shown separately of a member utilized in Figs. 2 to 4, and
  • Figure 6 shows a view of the loaded belt to a smaller scale.
  • the conveyer sections are supported by frames 1 spaced at intervals in known manner.
  • the flattened tops of the frames 1 are holed at 2 toreceive a bolt 3 having a shoulder 4.
  • An .L-shaped metal section 5 is supported on the 50. shoulder 4, and an L-shaped platefi rests on which are located beneath thewidth of thethe web of the section 5, the'plate 6 being.
  • the side plates 8 carry the anti-spillage shelves which comprise downwardlydirected inner portions 11 extending inwards towards the middle line of the 'conveyer at an angle of about to the horizontal.
  • the oblique inner portions of the anti-spillage shelves are surmounted at their outer upward ends by curved portions, 12 which areupwardlyj convex i. e. they are arcuate so that the upwardly extending portions 11 gradually curve off into horizontal elements.
  • the curvilinear portion is extended beyond the upper horizontal element until it ultimately forms a downwardly directed element 13 which serves as a means of attachment for the anti-spillage shelf to the side plates 8 by the intermediary of rivets 14;.
  • the anti-spillage shelves are formed in interrupted sections extending between adjacent bearings for the supporting rollers 15 for the belt 16, their downwardly directed webs being cut away obliquely as shown in Figs. 2 and 3 on the side of each bearing so that the bearings and shelves form a continuous channel to prevent material from falling onto the lower belt length.
  • the bearing proper comprises a block or casting provided with a central slot 22 to receive the spindle of the
  • the bearings 20, 21- Fig. 3, are supported 7 roller 15; the opposite bearings 21 are preferably closed it being assumed that the coal orothermaterial is thrown on the belt towards shaped to lie snugly undenthe-upper part 2 of the frame 1, thecentral;portion-being.
  • the bearings 22 are located beneaththe extended widthotthe belt 16 so that any spillage falling over" the edge" of the" belt intermediate the shelves will fall down the inclined face 23 of the casting and be prevente'd'froni' clogging'up the bearing for-the roller 5.
  • Other debris remainingbet'w'een theside plates 8 will remain on the shelves or be picked up'again by'the belt as its movement fluctuates.
  • the belt l6 lie'sjfust cl ar'otthetopotthe portion 12 of the an'ti s'pillage shelves which are only slightly lower than the tops of the rollers 15', 19, but when loade'dth'e belt is depressed and; contacts lightly with the anti-spillage shelves.
  • the belt As the belt is usually unevenly loaded, it'will' curve more or'less as it travels and willmake'a sliding contact with the arcuate" portions 12"of the shelves; Further, the belt usually swings from side to' side as it travels, and here again the margins ofthe belt will slide smoothlyup and downthearcth ate portions 12, making acontinuous seal against thepossibility' of dbris falling down the shelves between the side plates. Debris will,- of course, collect in theangl'e between the portions' 13" and theside plates but it cannot fall clear, and when the amount is'ex'cessive, it will be pushed about a little by the edges of th'e'belt during lateral swinging and will finally be caughtup again by the belt and carried away.
  • Figure- 6 shows the belt under excessive loading at a local point, and will be seen that as the belt recovers from this curv'easit approaci'iesa-roiler 15*, it will continuously prevent debris from falling un'de' r'the' edges. Owin'g't'o the obliquity of theinwardly inclined portion 11 of the anti spillage shelves, the belt is caused to take a substantially concave cross section which results inthrowing the material down into the centre of the belt.
  • Figure 6 shows the fihal' position under.
  • a belt conveyer a casting including; a bearinirfor a,roller, a pair-of supports for anti spillage shelves, and a webfor attachment to a supporting" frame.
  • a belt conveyer including a belt, rolling supports for'the' belt, anti-spillage shelves for cooperation with the edges of the belt supported intermediate the rollers, said shelves including arcuate portions underlying and extending beyond the edges of the belt. the arcuate portions of the shelves providing for sliding movement of the belt during travel without separation of the belt edges from such shelves.
  • a belt In a belt conveyer, a belt, roller supports therefor, and anti-spillage shelves supported intermediate the rollers and including a rounded area directly underlying the free edges of the belt and providing a belt contacting surface to facilitate sliding movement of the belt without separation, the shelves including a substantially flat area inwardly of the rounded area.
