Application filcfi October 31, 1910. Serial No. 5853,81 8.

To all whom it may can. m:

Be it known that I, NICHOLAS SoHAErnns, a citizen of the United States, residin rnt Ludlow, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Pneuu'mtic Car Dumping and Righting Devices, of which the following is :1. specification.

My invention relates to devices for pneumatically dumping 21nd righting c;

The object of my invention is to produce a device which dispenses with (he insuiiicient and dangerous chains and holding devices which MP6 in such common use on this style of dump car, and to provid or series of compressed air cylinders. which by means of mechanism (which will he (lescrihed herein) the engineer of a train of cars may put into operation by simply opening a valve or throwing it lever, as the case mny'hc, inside of the'engincefis cal).

Another object of my invention to pro vide a device which will enable the engineer or conductor to dump it whole train of cars together, either to one side or the other of the track or to dump the cars nlternn y to one side or the other without the as tune-e of any one stationed along the side of the cars.

Another object of my invention is to pro vide a pneumatic dumping device which may be operated to unlock, dump, right and lock While the train is in motion, the pneumatic mechanism being controlled by the engineer of the train, thus on. ing' train to he dumped while in motion it it found necessary or desimhle to do so. A still further object of my invention to'produce a device' which is more eliicient' than the devices now in use, and one which will save a, great amount of time, labor and -expense.

M'y invention-consists briefly in a series of compressed an cylinders and pistons,

-Which are connected together in such a man ner as to operate mechanism, which in turn throws the car into dumping position, to

one side or the other and then rights snii'l car, said compressed air cylinders being connected to the miiin conipressed air pipe e separate 'engineers train lines, which run perallei with the main supply pipe for the compressed air tanks.

My invention also consists in cert-sin detailsot const-ruction'and in the combine- I l r l l i l l i l I l l i l l l l l l l l i i i l I showing tion and m'nngeinent of ports herein se forth and claimed.

in 'ususi manner. The main com pressed sir line 1 of the ililiii extends -n the air pump on the engine ail along the rain of cars, means being provided. esusual for connecting and disconnect said line bet ween the csrs of the train. Each oer is provided with :1 pair of compressed air reservoirs 2 end 2', which. are coni'iected to the main train line 1 at, 3 and 3 asbest sit in Fig. 2. .g from the air resen voirs 2 and 2" are pipes end i which connect to three-way valves 5 and 5', said valves having pipes Z 8', i" and 8" respec tively connected thereto. The valves 5 and 5 are best illustrated in Figs. 4 and 9 where the pipes 41,, "Z and are shown con nected thereto. Two devices are required to operate the system properly, one to dump the chi? and the other to right said cur. Valve 5 (shown inFig. 4:) is provided with ii casing having four openings or ports therein. three of which are for the pipes which are connected ti lei-etc. and also allshows a preferred.

, openingor port 11 The openings or ports in said ivalve casings are preferablyiplaced ninety degrees apart, and a passage 12 is.

providedin the valve 5 connecting the port for pipe 7 and the port 11 or the port for 4, the air then passes from air reservoir 2 through pipe 4 through said valve stem 10 to pi e 8, thence to the releasing cylinder 13 w 1011 is suitably mounted on the top of I-beams or channel irons 14, which connect' the t-rucksC of the car together and form a platform for mounting or pivoting the body of the car upon the trucks. The pi'st-on rod 1 7 of-"said releasing cylinder .13, connects to an upwardly extending arm 18, mounted upon a shaft 19, which in turn is journaled in suitable bearings 20, OB he top of the platform formed by the Lb'e ms. pr channel bars 14. Mounted on one 'Ie 'd' of the shaft 19 outside of the bearing 2D,,as a rocker arm 21 disposed vertically thered'n and fastened thereto at its middle point A shaft 22 is mounted in! a. manner similar to'shaft 19-near the end of the'car in bearings 6 and 23 respectively and does not extend entirely across the car as does shaft 19, but only extends from bearings 6 to a 3 mounted at the opposite end of the car in- 5O point just beyond bearing 23. At the end of said shaft beyond the bearing 23 is a downwardly extending arm;24,tightly mounted thereon which is connected to the downwardly extending portion of the rocker arm 21 by means of a rod 25. The shaft 22 also has a laterally extending arm 26 adjacent the bearing 6 which carries a'hanging looking bar 28 at the endthei'eof. A shaft 27 is bearings 6 and 30 and also has. an upwardly extending arm 4 2 which is connected to the upwardly extending portion of the rocker arm 21 by connection made of any suitable material," An arm 26 is also mounted on said shaft-27 adjacent the bean ing 6' to which isat'ta'ched the hanging looking bar 28'. Thus shafts 22 and 27 are op erated together by means of connecting rod 70,- thereby operating the hanging locking bars 28 and 28 at the same time. Locking blocks 31 and 31 are mounted between the channel bars 14, as best shown in Figs. 3 and 8 and are each provided with vertical slots 32 and 32 which are adapted to receive the hanging locking bars 28 and 29, and 28 and orts therein 29' respectively. one of these locking blocks. is located atf'each end of the car directly above the two car body propelling wheels 35 and 35" respectively. These car body propelling wheels 35 and 35' are fixedly upon the propelling shaft 36 one at each\ end thereof, the propelling shaft being suitablymounted in bearings 37 fastened in any suitable mannerv to the channel irons or I- beams 14 and just underneath same so that the hanging locking bars fall adjacent the propelling wheels. The locking bars 28 and 28 extend or hang below the lower surface of the locking blocks 31 and are adapted to hang in the path of a cam 34 on the propelling wheel 35 and the corresponding cam on propelling wheel 35.

The car body propelling wheels 35 and 35 are each provided with two cams 33 and 34, which are adapted to engage with the locking bars which hang down through the locking blocks 31 and 31. Each of the car body propelling'wheels 35 and 35 are provided with grodves :38 and 39 in the rim thereof, in which; areplaced cables 40 and 41 respectively which are fastened to said wheel'and whichextend therefrom to the side of the car body to which they are securely, fastened. Die of the car body propelling wheels wit I the cams mounted thereon is best illustrated in Fig. 7. The cams 33 and 34 one on each side of the propelling wheels 35andg35: point in opposite directions and each engagetheir respective hanging locking bar 23-and 29, 28.and 29, By means of the hanging locking bars hanging in the path of saidcams the propelling 'wheels are prevented from turning in either direction as bestshown in Fig. 3.-

The car body propelling wheels which are provided with thecams '33 having a cam surface at the top thereof do not make a complete revolution when operated, as is readily seen by the position in which the cables 40 and 41 are fastened upon the car body propelling wheels in Fig. 1. If it were .not for the cam surface on the top of said cams 33, they wouldv immediately become blocked from returning to their normal positionas soon as they engaged the locking after the cams 33 have passed same, and before the propelling wheel returns to its normal position.;' For this reason I provide the cam surface so that it will cam the locking bar 29 upwardly, thereby allowing the propelling wheel to assume its proper normal position and automatically lock itselffrom forward movement again 'until the locking bars are properly operated. I

An engineers train line .1 extends paral- 101 to the main pipe line 1, to which is con-- nected a small pipe 15, which in turn connects to a compressed-air valve operating cylinder 43, and the piston rod 44 of said 115 bar 29, which falls t'o its normal position in order that when the piston rod 44 is op-v erated the valve 5 as shown in Fig. 9 will be operated .to' connect the pipes 4 and as shownin dotted lines in Fig. 9, thereby charging the dumping and righting cylinder50f direct through pipe 7, instead of the cylinder 13 piston 58. of the cylinder 50 outwardly and immediately operating the operating arm 59 which is connected by means of the flexible connection 62 around the roller 63- to the propelling wheel 64; mounted tightly on the propelling shaft 36 and thereby operating the propelling shaft in the proper direction toright the car. Of course when it is desired to dump the car in opposite directions, the valves 5 and 5 respectively must be changed or reversed to operate either the releasing cylinders 13 and 13 first, or the dumping and righting cylinders 50 and 50 first, as desired.

The valve 5 of the device is normally in the position shown ltl solid lines in Fig. l and the valve 5 oii-,tlie opposite side of the device is normally in the position shown in dotted'lines in FigL/l, the arm d5 n each case movingin the directionv of the arrow.

Thus it is seen that in the valve 5 the pas.

sageway 12 will be moved with the arm to connect thegpipes l and 8 together, while in the valve .5'; the passageway 12 will connect the pipesl 'r and 7 together when the arm 4:5 is operated. For instance the device as shown "in Figs. 1 and 2 is properly connected so as to dump the car to one side and when it is desired to dump the car to the other side, the engineers tragn line 65 1S charged to operate thelpiston rod 44C in the valve operating cylinder 43, thereby operating the arm of the arm 4550 valve 5'; The valve 5" is placed in a position corresponding to the position of the arms 45 shown in Fig. 4 so that when the piston rod ell operates the arm 45f of the valve 5 the pipes 4 and 8 are connected tmgether through sa d valve 5, thereby charging the COHlPYOSS8 air releasing cylinder 13, and operating its piston rod 17, which operates the arm'18,';wh1ch in turn operates the shaft 19, thereby operating the rocker arm 21.- Thejrockerarm 21' operates the con-' necting rod 2?)- connected between the lower extending portion of the rocker arm 21' and the downwardly extending a-rm'2 l mounted on 'hafti 2%, supported in a bearing 23.

The shaft 22 is journaled at the other end in a bearing 6' and is an entirely separate shaft from that shown at 27 and has mount ed adjacent bearing 6 an. arm 16. hanging locking bar 29 arm 16 and when said arm 16 is operated said hanging bar '29 is raised out of engage ment with its engaging cam on the propelthrough pipe 8 and forcing the' any car which The is attached to said ling wheel 35. A connectionis" connected between the upwardly extending portion of the rocker arm, 21 andthe 11pwardly extendin arm42 which is mounted on the shaft 27 ournaled in bearings 6 and 30. The shaft 27 is an entirely separate shaft from that shown at 2-2. An arm 16 corresponding to the arm 1-6 at the other end of the car is mounted on the shaft 27 adjacent -the'bearing 6. Thus when the rocker arm 21 is operated the shafts 27' and 22' are operated together, thereby operating the locking hanging bars 29 and 29 at'the same time, and thereby unlocking the propelling wheels to rotate in the proper direction.

Upon the return of the car body to its nor-v mal position. it is readily seen how it is stopped at the proper point by the propelling wheel cams 33 and 34 coming into contact with the hanging locking bars which are placed inthe path of the forward movement of thecams. v

When the device just described is used to dump thecar the opposite device must be connected properly to right the car, which simply means theeonnection of the valve 5 to operate the arm 45 and the piston rod l i of the compressed air valve operating cylinder 48:

It is readily seen that I have simply taken the device which was first described as dumping t e car, and placed another similar device on tie opposite side of the car, either device,to be used for dumping according to the side it is desired to dump the car. Either deivce may of course be connected to right .the ear.

In; loading a train of cars, certa n cars maylbe loaded unequally, thereby being unequally balanced and tending to cause one car -i o dump quicker than nether. This being the case, if onecar, or instance, is dumped before the car preceding it in the train, the car dumping first would robhe following car of its air, and thereby delay the following canfrom dumping. 'qTo prevent this unequal distribution of in the cars, I provide check valves 46 in the supply pipes leading to the reservoirs 2 and 2 respectively. The check-valves allow the air. to enter the tank fre ly, but prevent the air from backing out. ut-out valves 4-7 and 47 are also provided in the supply pipe for the reservoirs 2 and 2, respectively,to prevent said reservoirs from being charged when it is des red to cut out the device in disabled or is not intended to be dumped.

When a certain car is loaded more favorably for dumping to a particular side than other cars, after the engineers operating valve cylinder has been charged, and the air has passed up and the releasing cylinder has been operated to unlock the car body in order that it may for some reason or other is I into the lreleasing cylinder-,1

to the near side, which wruild carry the piedump, the car will dump immedi its favorable load, be the in the releasing cylinder has had a chance to fill up lhe dun'iping cylinder through loe pipe and by me: is of are car the pislon 58 of the (lumping cylinc been carried outwardly insl'ead of being forced oulwardly by the air, and forms a vacuum it were, for the air to rush in and fill said cylinder. denly rushes in will come from the poinrf cl"; highestpressure in the n, and as part of the pro sure has been used up in the air reservoirs oi l'his parlicular car, l'hereby ducing the pressure therein, and this car having dumped before lire car acceding it, it is natural lhal this air which rushes in would be laiien fro n the reservoir" and of the undumped preceding car. The check valves 46 and is serve to 1 "lain the normal high pressure in the reservoirs oi? such preceding car.
