ROLLER SUPPORT FOR ROTARY DUMPS.

Application filed September 6, 1927. Serial Ne. 217,810.

My invention relates to rotery cer dumping epperutus, more particularly to the supporting means for such epparetue, and hes for its object the provision of animproved roller support upon which the dump :is

edepted to rotzte'us it operzrtes. p

More speeficelly the ob1ectof my invention is to provide an improved roller support including rollers having hearing portiene of different diumeters whereby o relatirely wide &ngulur movement of the part el'- greeter diameter may be obteined with respect to the &ngulur ot smaller diameter.

It hee been the practice heretotore to pro- Vide rotery dunpe with riding ringe which were `Supported either upon rollers nounted movement of the part i on u fixed enis or upon rollers restng on e truck or support and having both bodily end mguhr movement responsve to the rqtetion My present nventon roller supports and its prime object is` to reduce to :L 'minimum the travel o'l' the roller support und to eiu'plil y and perfect the track elemente both on` the roller support and on the riding ring ol the rotery dump with which the roller& co-ect. Ii'rorder to reduce 'the linezl travel ot therollers, I provide a ditereutiul roller having its larger diameter portion co-icting with the rotory dump and 'its Smaller diameter portion co actng with the fixed truck or support, whereby Wide peripherul travel of the large diameter riding rings is red uced to e Very small lineul travel oi' the roller on its truck supports.

My inventiou 'Eur'the' contempletee so de- Signing the ditlerentizrl roller and 'its'trnck eupporte that itie beleuced in its work and will serve 'to hold the ridiug ring of the dump in correct position centrolly abovethe track.

My nventon further contemplutes the designing; of both the truck supports and the 'riding ring of 'the dump and the working surtucee ot the d'iffereutial roller so that all :rre protected by case herdened steel, thereby "providing great durability. i i i 1:\pperetue embodying 'Features of my `in- `Veiuion is "illuerzted in the uecomprrnying drewings forn'ing u port of this epecificeton, Wh erein i Fig. 1 ie en end elevetion of` a rotury dump provided with 'my improvedroller supports. p i i i i i l Fg.

wear of both the rings and the bearings, is provided with-a track 41, preferably made of case hardened steel, and extending around the channel member to form a hearing surface therefor.

The hearing members 33 and 34 are mainjtained in spaced relation by means of a segmental frame comprised of similar front and rear frame members 46 and 47. The members 46 and 47 are provided with holes 48 and 49 to accommodate pins 51 and 52 extending through the holes and through suitable holes provided in the axle portions 38 of the 'bear- 'ings The pins 51 and 52 are held in place with respect to the hearing by means of plates 53 secured to the member 46 by cap screws 54 and extending into suitably formed notches in the pins 51 and 52. The members 46 and 47 are held properly sp'aced by means -of a pair of short channels 56 and 57 `arranged It 'will be seen from a consideration of Fig. 1

that the members 46 and 47 hold the bearings 33 and 34 in properly spaced -relation at :in

:times The travel of the bearings islimited'at each end of the track by 'means of a curved stop 61 form'ed at .the uppervend of each of the track members, so that when either of the bearings reaches the stopits axle portions are engaged thereb and it is'prevented from further travel Thespacing of ,the bearings 33 and 34 and the arrangement'of the stops 61,

as will be seen from Fig. 1, are such that the bearings areat all times lisposed on opposite sides of the central verticalplane passing through the riding rings 16.

i In order -to protect the bearings 33 and 34 and the tracks ;36 and 37 from beingclogged with material when 'the cars are being i dumped, I provide the members 46 and 47 with inwardly extending lip portions '63 and' rotation of the riding rings16, when dumpi ing the cars, the bearlngs 33 and 34 are rotated by their contact with the riding rings i 16. Inasmuch as 'the axle portions 38 of the (with the stop 61.

V bearings bear upon the tracks-36 and 37, the

lineal movement of the bearings is obviously ?much less than that of the rings 16. Assum- :ing that the rings 16 are to be rotated to the left, as 'shown by the arrow iniFig. 1, a rotation of approximately 180 degrees thereo'f will only cause the-bearings to move `until the the a'xleportion'of the bearing 34 is engaged `The advantages of the ihereinbefore de scribed Construction will be clearly appreciated in that it affords a hearing support remarkably free from fr iction, and hence having a long life, and one which insures a proper support 'or the riding ring, whatever the angular movement 'of the dump.

lVhile I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible to various changes and modiieat ions, without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specilically set forth in the appended claims.

Having thus described my invention, what Iclaim as 'new and desire to secure by Letters Patent, is

In apparatus of the character described, a riding ring, a segmental track arranged beneath the ring, a plurality of movablc roller bearingsonthe trackand supporting the ring and adapted upon angular movement of the ring to roll along the track, said bearings each having an axle portion hearing on the track and a'body portion supporting the ring, the body portion being of greater diameter than the axle portion.
