Application led. May v 11,

To @ZZ/whom t mag/concerm o Be itknown that We, ARTHUR` Ga REEsEi and` PAUL H. DOUGLAS, citizens of the United States,. and residents, respectively, ,of Cleveland, in thecountyof CuyahogaI and State of Ohio, and ClevelandHeights, in.y the countygof Cuyahoga` .and State of Ohio, have invented a certain newand useful Improve.- ment in Tipples, of which the following is a full, clear, and exact description.

Thisl invention relates to car tipplesgen'- erally, but more particularly` to tipples tof the gravity operated-type in which the tipple is actuated by gravity bot-h, in itsidumping movementand in its return movement.

An object ofthe `invention is to.v provide a mounting for a rotatable car cradle inI which the frictional .resistance to thel move-V mentof the cradle is greatly reduced.

Al further object is to provide improved means for shifting the center of gravity of' the cradle to increase or decrease the initial turning impulse.

A further object is to provide improved mea-ns forholding said tipple in car receiving position, and for limiting the turning movement thereof in dumping.

A further object is to provide a tipple construction which will permit a tipple to be made of a length capable of'receiving any desired number of cars end to end andz yet `be successfully operated byv gravity.

Generally speaking, the invention may be said to comprise the elements and combinations thereof set forth in the accompanying claims.

In the annexed drawings forming a part of this specification, Fig. lis an end eleva-` tion of one of the rotary cradles; Fig. 2 is a side elevation of a'cradle; Fig. 3 is Aa diagrammatic plan view showing a multiple unit tipple adapted to receive a'` train of cars; Fig. 4 is a fragmentary detail viewv partly in section showing the end of the stop lever in engagement with the stop lug; Fig. 5 is a fragmentary side elevation of the head of the stop lever in engagement with the lug on the cradle; Fig. 6 is a detail view of the adjustable stop lug.

Referring to the annexed drawings, lined` supporting frames 1 are provided with laterally spaced supporting rollers 2 which have Smooth cylindrical peripheriesand are journaled in bearing brackets -3 iixed tothe supporting: beams. The. supporting rollers.

2 arefjournaled-iin'roller bearings to` reduce frictiona'l resistance toturning movement.

Each-,cradle consists of end supporting; rings 4 which may be-xmade of railroaderails, they i flanges `of the rails beingy on the. insidewandv the ball .of ithe railsforminga smooth cylin-. drical'surface-adaptedto rotate upon the supportingrollers 2. Longitudinal rails 5 connectxthe endsringsf4 and suitable dfi'agf` onal braces: 6 connect the longitudinal @rails intermediate the endfringsvv Central verf tical braces Lmayibe secured upon the llongitudinal rails 5.' lorizontaltrackr support;v ing` bars' 8'arefrigidlyconnected to the end ringsz4zf Vertical lsupporting barsy Slimay. be secured to thel centersof the crossabars 8 andato the rings. A'lraclrrailsv l0` aref mounted-uponlthe cross bars 8 and entendi A vided forholding the` car in place on the" track during-dumping. For that purpose we haveshown longitudinal axle engaging bars 12Ivvhichr are secured to the inner sides Y of the vertical side bars l1. l

In order to prevent endwise movement of thecradle7 thrust rollers 13 are journaled upon thesupporting beams l for rotation about4 a vertical axis and engage the balls of the ring rails4. Heretoforeit has been common practice tovprovide the supporting rollers with flanges engageable with the sides oflthe cradlerails to prevent endwise move ment.

thrusts against such flanges are aptto cre- However, vin a gravity` tipple-end a'tesutlicien-t friction to interfere with the* operation. By providing rollers to take ythe end thrust such frictional resistance is materially reduced.`

As shown in Figs. 1 and 2 arcuate plates 14 are secured uponthe flanges ofthe end rings 4.' The plates 14 have a series ofapertures 15 along their inner edges by Ameans-of which a counterweight 16 can loe ladjustably attached thereto. The counterweight'lconsist-s of one or more barsextending longi tudinally of the cradle and attached to the plates 14 on the end rings 4. The counterweight may be varied by substituting heavier or lighter bars orby increasing or decreasing the number. of bars or by shifting the bars along the arcuate plates 14. ln the car receiving position of the cradle the plates 14 are at one side of a vertical plane through the axis of the cradle so that the counterweight tends to cause the cradle to rotate.

For holding the cradle in car receiving position and for limiting the movement thereof, latch levers 17 are pivotally mount` ed on the fixed support at one side of the cradle. The vlatch levers 17 are each made up of two spaced bars 18 rigidly connected intermediate their ends by means of spacers 19. The lowerA ends ot the bars 18 of each of the levers have slots 20 therein adapted to lit over a pivot pin 21 carried by the fixed supporting beams 1. Between the bars 18 at the lower end of each lever a shackle 22 is pivotally mounted upon the pivotpin 2.1. Above the shackle 22 a channel bracket 23 is secured between the side bars 18. A rod 24 is secured to the pivotcd shackle 22, extends through the bracket 23 and has a coil spring 25 mounted thereon which is clamped against the bracket 23 by means of nuts 26 at the upper end ot the rod 24 beneath which is a washer 27 against which the upper end of the spring 25 bears. By adjusting the nuts 26 the compression ot the spring 25 can be varied and theilatch lever adjusted to hold the tipple with the Vrails 10 in alignment with the stationary track. The bars 18 oi each lever 17 straddle the ball of a rail forming an end ring 4 of the cradle and are provided with stop engaging portions 28 consisting of an inner lug engaging shoulder 29 and a flat lug engaging inner face 30 extending upwardly from the shoulder 29.

Rigidly secured to the web of the cradle ring rail 4 at one end of the cradle is a stop lug`31 which projects on opposite sides ot the web and engages with the shoulders r29 oi? the lever 17 at that end to retain the cradle in car receiving` position. Spaced somewhat more than 90 from the lug 3l is a similar lug 32 which is engageable with the shoulders 29 of the latch lever to limit the rotative movement ot' the cradle in the dumping operation. A lug 32 is mounted upon each of the cradle rings 4v while there is a lug 31 on one o't the rings 4 only. The lugs 32 are preferably adjustable along the rings 4 so that the extent ot movement ot the cradle in dumping may be varied.

To provide for such adjustment the webs of the ring rails 4 are provided with apertures 33 by means o't which the lugs 32 can be adjusted thereon.

Adjacent the lower end of the latch levers 17 U-shaped links 34 are pivotally attached thereto. The outer end of each link 34 is provided with a base portion 35 through which extends a rod 36 which is pivoted to a bracket 3701i the support 1. A coil spring 38 is mounted on the rod 36 inside the flange 35 and is clamped upon the flange 35 by means of a washer 39 and adjusting nuts 40. The coil springs 38 serve to yieldingly hold the latch head 28 in engagement with the flanges ot' the rings 4. Y

Connecting the bars 18 of each of the latch levers 17 at the rear of the shoulders 29 is a pin 41. The latch lever which engages the ring rail 4 which is not provided with a lug 31 has a wide roller 42 on the pin 41 which engages the ball of the rail. The other latch lever has a narrower'roller 43 thereon and a lever 44 which has an eye portion 45 adapted to receive the roller 43 and is pivcted to the pin 41 at the sides of the roller. The rounded upper end of the lever 44 is engageable with the ball of the ring rail to disengage the latch lever 17 Jfrom the stop lugs 31 to permit the cradle to turn to dumping position.

When a loaded car has been positioned in the cradle the lever 44 is actuated to withdraw the stop'shoulders 29 from engagement with the lug 31. Since thek center oi' gravity by reason of the location of the counterweight 16 is at the side of the axis of rotation opposite the lug 31, the cradle will rotate in a direction to invert the car until the stop lugs 32 come into engagement with the stop shoulders 29 ot the latch levers.

The impact of the lugs 32 against the shoulders 29 is taken up by the shock absorbing` spring 25 which permits the lever to move longitudinally for a limited distance. When the car is dumped the center of gravity is shifted to the side of the axis toward the latch levers 17 by reason of the tact that the car trucks are` then positioned on that side ot the axis. This causes the direction ot rotation of the cradle to be reversed. 0n return movement of the cradle the lug 31 engages the fiat faces 30 of its latch lever and forces the lever outwardly to permit the lug to pass. The lug 31 will move slightly past the stop shoulders 29 and return into engagement therewith holding the cradle in position to permit the empty cars to be removed and full cars to be placed thereon.

ln constructing tipples oit a length to receive a train of cars it is necessary to provide a considerable number' of sets of supporting rollers and it is diiiicult to avoid excessive frictional resistance of turning movement due to the fact that some oif the rollers are apt to settle causing intermediate portions of the tipple to sag. To avoid this diiiiculty our tipple is constructed as shown in 3 of a series of independently mounted aligned units, each unit consisting off a rotary cradle such as shown in Figs. 1 and 2.

To a cross-bar at the ends of the cradles causedto rotate in unison. A slight settling of the supports for one of the cradles does not interfere with the operation since the entire Weight of each unit is carried by its own supporting rollers and the linlis Willv permit relative vertical movement between adjacent units Without interfering'ivitlithe rotation of the tipple. i* The positionsrot the center of gravity oftlie tipple before, during and afterA dumping, are indicated diagrammatically in Fig. l.

C is the central axis of the cradle which preferably coincidesrvith the aXis of the couplings between Vthe cars so that cars may be dumped Without being uncoupled from the train. Small -circles G, G2 and G3' indicate respectively, Ythe center of gravity ofthe tipple with a loadedrcar thereon ready to be dumped, the center 'of gravity of the tipple the/limit of its swinging. movenient, andthe center of gravity after. the return ot' the tipple with the empty car thereon.
