earth, and other materials and substances which may readily be discharged from such cars by gravity, as through drop-bottoms, without the necessity of unloading the same manually or in any other positive manner. While drop-bottom cars'have hitherto been constructed, no such car has been provided and organized in such manner as to permit of a diversity of distributions or flows or discharges of the material, so that it might be directed either downwardly, laterally, or both laterally and downwardly, or convergingly downwardly, that is, in streams proceeding from opposite sides of the car, or divergently downwardly in streams proceeding from opposite sides of the car. Ordinarily such drop-bottom cars merely provide for and permit the mere dumping or dropping of the load ina discharging action sub stantially vertical, and not subjectto the possibility of producing diversified direction of flow or discharge to distribute or disppse ordirec't or deflect the load or portions thereof in a predetermined manner and for definite obj ects and purposes. Inaccordance with the present invention, and the diversified directions and manners" in which the load and its portions may be discharged or directed, many useful and beneficial objects may be attained, substantially automatically, and which objects have heretofore been capable of accomplishment only by costly and time-consuming manual and other operations. For instance, in accordance with the present invention, I vprovide a dropgbottom car from which-loads of coal, cement 'earth,

gravel, sand or other broken or comminuted or finely divided fnaterials may be dis charged in two streams, in opposite lateral directions, as into separate binsor receptacles or pilesorupon the sides of the right of way for building embankments or fills. Or, the load may be discharged all toward one side-or the other, er it may be discharged all substantially 'along the longitudinal medlan line ofthec-ar, as for instance, in depositing or distributingballast upon a roadbed. All of this is accomplished by a certain provision and combination and interrelation and association of parts. and features, subject and responsive to control to produce predetermined results, and in fact,

subject to absolute control without disturbance'of any working condition set up and desired to be maintained. In other words,the

parts and features when set up and arranged and adjusted for one particular dumping action or unloading or distributing action, are

locked against any disturbance of such condition or adjustment until voluntarily released to restore the parts and features to their normal positions or conditions or to throw them into other positions or bring them into other conditions.

The-invention has for its object the provision of improved rolling stock of the general character stated which willbe superior in point of relative simplicity and inexpensiveness of construction and organization, taken in conjunction with positiveness and efficiency and reliability in service, definite.

ness and convenience in control, durability, freedom from liability to get out of repair, and adaptability to a wide range of conditions of use and service, and which will be generally superior in efliclency and servlceability.

lVith the above and other objects in View, the invention consists in the novel and useful provision, formation, construction, combination, organization, inter-relation and association of parts, members and features, all as hereinafter describech'shown in the drawings, and fin-ally pointed out in claims.

Fig. 13 is a detail transverse sectional view taken upon the line m -w Fig. 1, and looking in the direction of the accompanying arrows.

Figs. 8 to 13 inclusive, are upon enlarged scales.

Corresponding parts in all the figures are designated by the same reference characters.

Referring with particularity to the drawings, the improved railway car shown therein comprises longitudinal side sills or frame members 14: and a central longitudinal frame member or beam 15, together with the usual upright side walls 16, end walls 17, and end sills 18. In these respects the general frame construction of the car may be in accordance with preference, all within the limits of suitable durability and proper railway practice. At each side of the longitudinal beam 15 is a series or plurality of drop-sections a, which are adapted to be deflected, each, laterally in either direction, as clearly disclosed in Figs. 8 to 12 inclusive, with the exception of certain drop-sections b at each end of the car, two at each side at each end, which are adapted each to drop or tilt only in one direction, and that toward the side of the car at which such drop section is disposed. At each side of the car, longitudinally, is provided a pair of rock shafts, a and (Z respectively, and which are journaled in connection with the frame members of the car, and are provided with dogs e which co-engage with hooked edge portions 19 upon the section a, to maintain the respective edge portions in normal positions, that is, in positions coincident with the plane in which such drop-sections lie when horizontally disposed. These dogs and hooked edge portions of the drop-sections cooperate with supporting members f, a plurality of which are disposed at each side of the longitudinal center of the car, in a series extending longitudinally of the car, and mounted upon a rock shaft 20. These rock shafts are journaled in hangers 21 which extend transversely of the car between the central longitudinal beam 15 and the side frame members 14. These supporting members f are preferably cam or sector-shaped, their arcuate crowns being provided with rollers or anti-friction devices 22 adapted to engage the drop-sections a and b, and to limit the drop action of each of the same in either direction permitted by suitable :0 Fig. 2, and looking in adjustment of the dogs e, and also adapted to furnish the main support for the respective drop-section when the same is in hori zontal or normal position, and thus in the main support, that portion of the load of the car disposed upon such drop-section, all as shown in Figs. 8 to 13 inclusive. The rock shaft 20 and rock shafts 0 and (Z are all interrupted centrally of the car, that is, centrally between the ends of the car, so that the car is subdivided into two working units, each of which includes half of the drop-sections a, one pair of drop-sections 6, half of the supporting means or cam members f, and half of the dogs 6. At each end of each half of the rock shaft 20, and at each end of the car, is provided a pinion 23 fixed to such shaft, and which meshes with a gear 24 fixed upon a short stub shaft 25, mounted in the respective end sill 18. For each gear 24 is an operating arm 26 whereby the respective rock shaft may be operated to throw the supporting members or cam members 7 upon it into any one of the posi tions indicated in Figs. 8 to 13 inclusive. B designates locking means disposed at each end of the car and at each side of each end of the car for the two rock shafts c and cl and the rock shaft 20, the ends of which terminate at each side of each end of the car. These locking means comprise in the first place, locking plates 27 upon the shafts d and 28 upon the shafts 0, and locking plates 29 upon the shafts 20. With these locking plates cooperate locking fingers 27 for the plates 27, 28 for the plates 28, and 29 for the plates 29. Each finger 27 together with a finger 29 is mounted upon a locking arm 30 which is pivotally connected as at 31 with the respective rock shaft 0.

Each of the locking fingers 28 with one of the locking fingers 29 is mounted upon a locking arm 32 which is pivotally connected as at 33 with the respective rock shaft (Z. The rock shafts o have crank arms 34 at their ends, at the ends of the car, and by these such rock shafts may be turned. The rock shafts (Z have pivoted operating arms or cranks 35 at their ends, at the ends of the car, and by these the rock shafts (i may be turned, such pivoted arms 35 being adapted to be swung over stops 36 at the ends of the car, to prevent turning of the shafts (Z until such pivoted arms are released from such stops. The locking arms 30 and 32 are guided at their locking fingers or terminal portions 27 and 28 in suitable openings in the frame members it of the car, as indicated in Fig. 2, and in Fig. 4 in section. Any suitable arrangement and mounting of these locking arms may be adopted, as will be obvious.

The operation, method of use and advantages of the improvements in rolling of the car.

stock or railway cars will be readily understood from the foregoing description, taken in connection with theaccompanying drawings, and the following statement:

Normally the drop-sections a and b are in horizontal positions, asshown in Fig. 7 or Fig. 1, or as indicated in Fig. 8 as to the sections a. The sections 6 are operated in the same manner as the sections a, in tilting or dropping them downwardly and laterally toward the sides of the car, as shown in Fig. 13, but their inner hooked edge portions '19 are permanently engaged with fixed dogs is upon the central frame member 15 The drop-sections in normal positions are in the main supported with their loads by the supporting or cam members f, and are incidentally supported by the dogs 6 or fixed dogs with the movable dogs 6, in consideration of the drop-sect ons b. If it be desired to tilt the drop-sectlons downwardly and outwardly at each side of the car, as shown in Fig. 11, toward the same side of the car, as shown in Fig. 9, orin Fig. 10, or toward the center of the car as shown in Fig. 12, or as to the sectlon b downwardly and oppositely, as shown 1n Fig. 13, the rock shafts c and d are manipulated to release the drop-sections a or 2') accordingly, by freeing the hooked edge portions 19 of the drop-sections from the respective dogs, and thus permitting the resultant slant or inclination of the drop-sections to occur. Such, however, only occurs after the rock shafts 20 are suitably turned, both being turned if inclination of bothlateral series of drop-sections is required, and

only one being turned if only one lateral series of drop-sections is desired to be tilted. This is done either by manipulating the nXed cranks 34- or the pivoted cranks 85. It is impossible to manipulate both the rock shaft 0 and d at either side of the car, but the rock shaft 0 at one side may be rocked with the rock shaft 0! at the other side. Thus it is impossible to release the sections a at both side edges so as to entirely drop the same or free them so that they may be displaced entirely. This is due to the operation of the locking means B, whereby, as will be readily perceived, if the rock shaft 0 atone side of the car is turned, the looking fingers 27 cooperating with the plate 27 prevents the rock shaft d from being turned; and reciprocally if the rock shaft cl be turned the locking finger 28 cooperates with the locking plate 28 to prevent the rock shaft 0 from being turned. Likewise, whenever either rock shaft is turned the respective rock shaft 20 at the same side of the car is locked against turning in one direction by the respective locking finger 29 cooperating with the locking plate 29. This permits such rock shaft 20 to be turned through the pinion 28 and gear 24 by the operating arm 26 only in that direction which will permit the supporting and cam quent upon the rocking of the respective rock shaft 0 or (Z. In other words, after either such rock shaft at one side of the car is turned, the rock shaft 20 at the same side of the car and associated with that group of drop-sections, may be turned to incline the members f connected with it so as'to permit the respective drop-sections to take the inclinations for which they have been released, all as clearly indicated in Figs. 8.to 13 inclusive. When the rock shaft 20 has been thus turned the respective drop sections a come to rest upon such members which serve as supports for the same when in inclination, in conjunction with the hooked edge portions 19 and the co-engaging dogs 6 or 70 which are still in cooperation. The object of permanently supporting the bottom-sections b at their inside lateral edges is to prevent tilting of these sections 6 toward the center of the car, which would result in a load thereof being discharged onto the trucks and wheels of the car.

It is manifest that by the use of this invention the load in the car, at each end of the same, may be discharged entirely toward either side of the car, half toward each side of the car or entirely toward the center of the car,all as the requirements of unloading, road-way building, ballasting, filling, embanking or other operation may require.

It is manifest that the invention provides for a car organization which is of extreme versatility and adaptability to varyingdemands of unloading or road building or re pairing or the like, and adaptability to many various and widely varying uses, and that many changes and departures from the construction herein disclosed and pictured in the drawings, may be made, in adapting the invention to varying conditions of use and service, without departing from the spirit of the invention. 7
