HENRY FORT FLOWERS, OF NEW YORK, N. Y.

DUMPING- CAR.

Application filed November 27, 1914 To all whom: it may concern:

Be it known that I, HENRY FORT FLOW- 161 s, a citizen of the United States, anda resident of the city of New York borough of Manhattan, in the county and State of New Yorlghave invented certain new and useful Improvements in Dumping-Cal's, of which the following is a specification.

One of the objects of my invention is to construct a dumping ear having a body which is movable horizontally across the under frame and which is then tilted so as to discharge the load.

Another object of the invention is to de sign a car so that it will have a tilting body that will be maintained at a minimum height above the underframe and track and which at the same time, will be able to deposit its lading, when dumped, at a point sutliciently distant from a, track or roadway to enable other cars to pass along the same track without obstruction.

A further object of the invention is to provide a car which will combine the advantages of a car having a side tilting body, which will be suitable for use as a general service car, and which car will permit dump ing of the load between the. tracks.

The invention involves an operating mechanism for tilting a dumping body to either side, a dumping or tilting body that is provided with trap or bottom doors which are so constructed as not to interfere with the side tilting operations, and adesign of under-frame that facilitates the employment of this combination of bottom dumping and side tilting body.

The car which is the basis of this appli cation is comparatively simple and inexpensive to make, and one that requires only a relatively small amount of power for its operation.

The invention particularly relates to a tilting body mounted on rollers that move horizontally on a track on the under-frame in such a manner that the body moves faster than and in the same direction as the rollers until the body starts to tilt, from which time the rollers and the body may move together one and the rollers serve as rockers. The centers of these rockers are located so that from the time the tilting of the body he gins up to the time that the lading is being actually discharged, the body may be easily retained in any desired position and so that after the discharge of'tlie ladmg the body Specification of Letters Patent.

will automatically, or at least tend to automatically, resume its original horizontal position by force of gravity.

This invention also relates to a power transmitting mechanism, comprising a fiexible power transmitting member, for produc ing the horizontal and tilting motions of the body; and a mechanism whereby the doors may be automatically opened as the body approaches its dumping position. This invention is also directed to a mechanism l or operating the trap doors that may be provided in the bottom of the tilting body. The flexible power transmitter preferably a rope or chain, operates on a series of sheaves, at, least two of which, of different diameters, are rigidly connected together so as to provide a differential gearing which accomplishes a great multiplication of the force applied to at least one of the sl'ieaves, or of any external force applied to the flexible power transmitting member.

The car is also provided with a door catch or door gear mechanism which comprises an eccentric or toggle link constructed so as to accomplish four things:

First to open simnltanemlsly and autonnitirally W129i") desired, all of the doors on the down or disrhargc side the body tilts and approaches the discharging position.

Second, to open any on or more'eatches without disturbing the others that aretattached to the same shaft.

lliirrl to open ali oi tin; catches on one side simultaneously with a hand lever at either end of the body, and

Fourth. to catch all of the doors and pull them up tight to the body by the operation only of the last mentioned lever.

This construction permits the body to individual doors so that dlflerent kinds of material may be hauled at the same time, and dmnpod at dill'erent points.

Some of the advantages of my invention are that it affords the construction of a twoway dump-car that is particularly adaptable to railway service and that especially overcomes the difiiculties of dumping. the lading clear of the track where the top of the rail is at grade level; and that it also provides a construction of car having a dumping body that will have side boards or doors close to the ground and hence make the loading height a minimum.

The invention furthermore facilitates the construction. of e side dumpin our havin a tilting body that may be revo vcd throng i a large dumping angle for insuring a (llH- charge of any material that lies a tendency to stick in the body. The invention also permits u our to be ealized whirl) cm 'iloys a tilting, body which is so bzilziucrd that soon as its load is discharged it will have it tendency to revolve back to its horizontal position. without the application of any power other than that attained by virtue of the shifting of the center of gravity when the load is discharged. The invention enables the construction of a, low self clearing side dumping car that is serviceable in mines where the overhead height is limited and Where, at the some time, a large tilting angle sufficient to discharge the loud is required, be the loud wet loam or any of the ineterials that require more than a. forty-five degree on Io fordumping.

.he car oinprises the trucks A, the luidcrairzuue Ii, the lilting body C and the mechanism 1.) for operating the tilting body.

The body is provided with swinging si e doors l) and o erating gearing or locking mechanism I therefor. The undcr-frame is constructml so that doors (i can be placed in the bottom of the ear whereby as discharge of the load on the ground between the tracks run he ollected through the openings for said last mentioned doors, if desired.

The. door locking nu-rhanisni l" is conslrlu'lod so that it run cooperate with the undculrmnr, sue slop-member H on the lat ter, whereby as the tilting body approaches the extremity oi its tilting position the swinging side tlUOl'o. l) n the lower side of the lmdf. will be automatically unlocked.

The tilting boil; i supported on the xnnlcrirnine ll by menus of the rollers K, and there is provided between said body and the under-frame mechanism comprising cleats L and ways M for insuring the stability of the body on the under-frame when the body is in load carrying position. The car i also provided with suitable body looking ineohanisin as N for positively retaining the body in. central position when the car is in transit.

The trucks A may be of any suitable construction as long as they are adapted to carry the under-frame, body, and its lead. lhey may also be of either the motor type or the nonniotor type, dependent upon whether the car is to be self-propelled, or whether it is to be hauled by some other power.

The under-frame B a longitudinally extending main center sill construction 1 and two longitudinally extending side sills 2, that are positioned over the side bearings 23. The side sills are arranged as far as possible from the center sill so as to permit the load to be dumped between the center sill and the side sills through comparatively large openin s such as are provided For the trap-d0ors in the bottom of the body C. It will be observed, however, that the extreme outward position of the side sills is determined by the clearance required for the body when in tilted position, since there must be no interference with the movement of said body said side sills. The under-frame is also provided with the needle beams 4 and the body which are rigidly secured to said "ills whereby a rigid built-up structureis roduced.

The bottom body C may have only a. single compartment, but in the form shown preferably comprises.

The rollers K rest upon the tracks 8 that are carried on or constitute a part of the under-frame. These rollers K roll along said tracks when the body C is being moved from load carrying position shown in full ines in Fig. 1 to the tilted position shown The cars are provided with the angle iron tracltrncinhers, such as 9, and the lower flanges of the I-beams in the transverse partitions serve see 10. These tracks 5) and 10 rest upon the rollers K whereby the car ho is roper su orted.

g gz re errin to 2 and 4 it will be noticed that t e point CG reprcsentin the location of the center of gravity of the ody when empty is below tracks 9 and 10, which are the lines of support of the tilting body.

From an inspection of Fig. 2 it will be ollserved that the rollers K are arranged in pairs and connected together by links 11. It Will also furthermore. be noted that the car body travels twice as far as the center line of the rollers until the body starts to tilt, from which time the rollers on the tilting side and the body move together, the body and rollers swinging together, as one, with the rollers acting as rockers.

It will be ob served that when the car body is near the end of its travel toward the side of the car which are nearis to be dumped are on the car body, to wit, upon the portions marked 13 of the car body. When this engagement takes lace further relative horizontal move ment etween the rollers and the car body cannot take place and from. then on the rollers which are at the side to which the load is to be dumped serve as rockers upon which the body swings from horizontal to Since the stop 13 is arspindles 12 can be practically in line with the vertical center line of the car the load is y can take place. The roller spin- -dles 12, however, are sufliciently away from the center of gravity whereby, when the load has been actually discharged, the body'will to horizontal position and in fact during the latter part of its movemerit toward horizontal position the body itself to said body can be carrying or central posioperating mechanism D.

flheeenter of gravity of the body is on the y cal center line and is approximately at f ,point marked CG in Fig. 2.

In Fig. i. ii. will be soon tlmtthe tracks r on the under-Frame are, lll the middle portion of the car in the arranged withthcil' flanges iip-stanrling so that said flanges can serve as stops for receiving any longitmiinai imparted thereto by means of the lower portions 1.? on the car body engaging with said. flanges. These flanges are designated 1157", f f etc. There is suiiicicnt play, however, between the upstanding flanges and the pm tions 17 to permit a free lateral movement of the car body along snii'l tracks or trans versely oi the undci frazuc.

The mechanism .1) For orienting the tilting body com; :s: hand wlnwcls 35 7 llXull at each end 01" th l-mgil'mlinril shaft l9 which extends the toll long-iii oi the car body. This shaft is nuumtod so that it may freely resolve in a casing :30. in the construction silo-m1. this shaft and casing therefor is arranged along the longitudinal central portion of the car bod, but this shaft and easing may be located at the side ofthe car, for instance along the upper hinged portion of the doors, it for any desirable to remove the shaft from the can tral portion of the car toward the side thereof. Thcshaft 19 could be located elsewhere, if desired, the principal function of this shaft being to cause the operating mecha nism at the opposite ends of the car to act in unison. Double groove-d sprocket sheaves are rigidly fixed to opposite ends of the shaft 19 and these sprocket sheaves are of such a construction as to effect a positive drive or the chains 22, one of which chains is located at one end of the car and the other of which is located at the other end of the car. As the construction at each end of the car is substantially the same a descriptionof the mechanism employer] at one end will suffice for both. The flexible member is preferably an. endless chain which passes (see Figs. 1, i and i) from the groove 23 of the double-sheave 21 down to sheave 24; then to the left to the horizontal sheave 25 back to the right to the vertical sheave 26; thence up to the second groove 27 of the double sheave 21; thence down to the vertical sheave 28 to the right to the form of char:net-irons thrusts which arereason it becomes the vertical.

horizontal sheave 29, to the vertical sheave are called vertical sheaves because they rotate in vertical planes. The H shafting for these sheaves is supported by the frame or bracket supported on the end of the car body. The sheaves 25 and 29 are all idler sheaves and they are called horizontal sheaves because they rotate in horizontal lanes. These horizontal sheaves are rotatab ly mounted on the under-frame.

Due to the fact that the diameter of the groove 23 in the double grooved sprocket sheave 21 is larger than the groove 27 there will be produced a differential movement of the dilferent portions of the chain gearing passing over said sheave 21 and, consequently, the vertical grooved idler sheaves will be pulled as a set either to the right or the left, dependent upon the direction in wnich the hand-wheel 18 is rotated. As this pulling operation proceeds it causes a lateral or transverse movement of the car body as a whole relative to the under-frame where by the body can be forcibly moved from its central or load carrying position to either the right or left. When the body is in substantially the extreme right or left position, as the case may be, the car body stops 13 en age the proper set of roller spindles 12 and mm then on the car body tilts around the proper set of rollers or spindles 12 as rockers, so as to dump the load in the de sired osition.

As efore indicated, when the load or lad ing has been discharged from the car body the car body tends to automatically restore itself to horizontal position and it can be assisted in this movement, if desired, by the endless chain gearing mechanism just re ferred to. To insure the stability of the car body cleats L are provided on the underframe near the sides thereof, and these cleats coiiperate with ways or flanges M on the car body, when the latter is in central position. The ways and cleats are arranged so that disengagement can take place prior to the body starting to tilt.

The under-frame also has pivotally mou nted thereupon a latch of the locking mechanism N, which latch is arranged to engage the car body or some member thereupon, such as the bracket or frame for supporting the shafting of the fopr idler vertical sheaves, for ositively retaining the car body in its eentral position on the under-frame.

Specifically the locking mechanism N comprises a double locking bar 50, to wit the latch above referred to, that is pivotally mounted at 51 upon the main center sill 1 and 54 of the locking bar are located upon opposite sides of a projecting member 55 that extends from an end of the tilting body. There is a locking mechanism at each end of the car.

As previously stated the car is provided with swmgin i doors E," There is a swinging door at eac end of each compartment provided in the car body and these doors are secured in place by the hinges 31 whose pivotal points are located long the upper edge of the car body as at 32. hese doors E are mounted so that they can be so cured in position by the catches 3" whose operation will hereinafter be described more in detail, but so that they can swing to the position shown at the lower right hand end of Fig. 2. These doors are furthermore constructed so that when the catch 33 is raised from the full line to the dotted line position shown at the left hand end of F g. 2 the door can be SWHH from the full line po sition to the dotted inc position show the left hand end of said figure, whereby the car can be loaded by material thrown in the car body from below the door, should such a method of loading be desired. In order to provide a receiving space which will permit a sufiicient movement of the catch from its door holding position to a position where the door will be free to swing, openings 34; are provided through which the catches pass. Longitudinally extending door latch gear operating shafts 35 are provided along each side of the car These shafts are located below the floor bottom of the car body and each shaft has thereupon several sets of crank arms 36 to which are pivotally connected at the free ends the several door catches 33. The shafts 35 are also provided with other crank arms 37 which constitute a part of the mechanisms between the shafts and the under-frame whereby the desired shaft 35 or shafts should there be more than one at each side of the car) will be caused to partially rotate as the body approaches its full tilted position. Slotted levers 38 are carried on pivot pins 39 that are secured to the car body. One end of each of these slotted levers 38 is directly connected to a crank arm 37 and another por tion of the 1 ver 38 is arranged so that as the body assui es the full tilted position just referred to said lever will enga e the stop H that is on the under-frame. t will thus be observed from an inspection of Fig, I, that as the right hand end of the car body lowers the upper or free end of the lever 38 will ress against the stop, turning about the pivot 39 as a fulcrum, and thus cause the free end of the arm 37 to move so as to pa.- tially rotate the shaft 35 which carries said arm. The partial rotation of this shaft I, causes the lower free ends of the crank arms by means of a pin 52. The spaced ends 53 36 to move downwardly and this downward movement of the free end of the crank arm 36 causes the lifting of the free end of the catches a 33 which are on the discharge side of the car, since said catches will rest upon the shaft 35, or the hub portion of the crank arms 36, as a fulcrum point, and will thus turn with the shaft.

The shafts 35 are also provided, with shaft operating handles 40 for manually releasing opening in the under-frame.

V a horizontal position.

From an inspection of Fig, 2 it will be noted that there is nothing above the catches 33 for preventing any one or more of them being moved upwarly independent of the others. This is of considerable advantage where it is desired to open only one or a few of the swinging doors; as, for instance, when only a. portion of the load is to be dumped. The door cutch-cranlbarms 36 just referred to are of considerable advantage in the locking of the swinging doors E in their closed position, because by the swinging of j the handle 4.0 from the position Y to the position Z the crank arm 36 moves the catch so that the door engagin portion thereof will move outwardly a su stantial distance beyond the position it occupies when holding the door in closed position, thus enabling the catch 33 to properly engage the door by gravity should the letter be a substantial distance away from its final closed position, due to an gravel or other obstructi on which may possi ly cause it to stick. lihen the handle 40 is forced from the position Z back to the 'position Y it will cause the catch 33, due to the crank arm 36 being moved, to pull the door to its final closed osii'ion Where the crank arm holds and loo {5 the catch in p0 siiion, due to the toggle link construction ,efiploye Cars of the class under'consideration are frequently used to carry ladings of different character; for instance, stone in one compartment, cement in another, and sand in another, and it frequently is desirous to discharge only one compartment and allow the rest of the compartments to retain their ladings. Such a discharge is permitted, due to the construction just referred to.

As it is not always desirable to have all of the doors dump automatically, the stop H can be made removable, as by making the stop construction to comprise a re movable bar which is inserted through an Such a construction is illustrated in the drawings in Fig. 1*, in which the stop H appears as a shouldered bar that slides in the socket provided by the member 56.

It is often desirable to have a car constructed so that it will empty a part of the load to one side, but at a comparatively remote distance from the track, and to empty another art of the load directly upon the tracks. 0 permit the latter to take place I have provided. the compartments with trap-doors. These trap-doors are indicated by the reference. character G and two are shown for each compartment. These trapdoOrs are arranged so that when they are removed from door closing position the load can pass downward through the space he tween the center sill 1 and the side sills 2. In Figs. 5, 6 and 7 the operating gears for these doors are clearly shown. As very little space is permitted for the trap-doors and this operating mechanism between the bottom oi. the car and the top of the underframe the doors are made so as to Slide horizontally, and they rest upon the rollers ll whose movement is one-half of the total miwemcnt oi. the car doors that they support. The position of the rollers 41 when the door open, is indicated at X. in Fig. 5 the doors are each provided with racks 42 that are engaged by the pinions 43 which are on the hand operated shafts 44.

It will thus be manifest that the car herein described is a side dumping car of the tilting type, that is also applicable for general service conditions, and that it is provided with doorswhich. permit a discharge of the load past or throu h the under-frame directly upon the ground ietween the tracks.

It should be noted that the car construction is suchthat when the load is placed far enough to one side of the car to cause an over-balancing of the body before the stops lflengage the spindles 12 the bod may begin to tilt as soon as one end of eac of the flanges M (see Figs. 1, 4- and 5) clears or discngages the cleats L that retain the body in horizontal position on the underframe. Hence, the body may be tilted without utilizing the function of the stops 13,

provided the body is permitted to do so b the body operating mechanism D, which mechanism may be utilized as a means for preventin a complete tilting of the body when the latter starts to tilt under the conditions just referred to.

The rollers K may have peripheries, for instance, two of different lengths or diameters, and the body may .rest 11 on one of these peripheral portions whi e another peripheral portion the under-frame. shown in Fig. 4'. frame traclober is the larger peripheral portions 5858 of the roller rest upon the under-frame track-bar 57. A body track-bar 59 rests upon the In this figure the under smaller peripheral portion 60'-the portion of the roller having the smaller diameter. The limiting diameter of the larger one of these peripheral portions is the extreme elkthe roller; the limiting ternal diameter of diameter of the smaller peripheral portion is a small journal near the center of the roller. According to all however, of that plhase of the invention which is related to t body on bodily movable rollers, the rollers will move in the same direction as the car body moves when the latter is being transferred from its central load carrying position toward the side of the car.

A dumpin Car or other vehicle of the class described aving in combination with the main under-frame thereof a tilting body that is provided thereupon with transversely extending tracks, rollers which are mounted upon tracks on the under-frame and upon which rollers the tracks upon the tilting body are supported whereby the body can be moved toward either side of the car, said tracks being provided with projecting portions or teeth which enter notched portions in the rollers, the construction and arrangement of said tracks and rollers being such that when the car body is moved toward the side of the car the rollers will be moved toward the same side of the car.

10. In a car or other vehicle of the class described an under-frame, rollers thereupon and arranged in airs so that each pair can move transverse y relative to the underframe, a tilting body resting on said rollers, and mechanism for shlftin the body horizontally to either side unti the body starts to tilt, and which mechanism is constructed so as to permit the body to tilt, the construction of the rollers and the body being such that the body travels substantially twice as far as the center lines of the rollers until the body starts to tilt, from which time the rollers on the side to which the body is tilted move with the body and serve as rockers.

11. A car of the class described comprising a longitudinally extending underframe having thereon horizontally transversely extendi' tracks, rollers on said tracks and movab e along the same, a tilting body havin track members which extend horizonta y and transversely, when the body is in central or load carrying position, and which track members rest upon said rollers whereb the body is supported by means of the rol ers, said body track members being above the center of gravity of the body when empty.

12. A dumping car or other vehicle of the class described having in combination with the main underframe thereof a tilting body that is provided with transversely extending tracks, said tracks being located above the center of gravity of the body,the rollers mounted upon tracks which are upon the underframe, upon which rollers said tracks uplon the body members are supported w ereby the bod can be moved to either side of the car, t e construction being such that when the bod is moved toward a side of the car the rol ers will be moved along the tracks on the underframe and the tracks on the body will be moved longitudinally relative to the rollers.

This specification si ed and witnessed this 24th day of Novem er, A. D. 1914.
