This invention relates to a car particularly adapted for transportation of cement or the like in bulk.

In order to transport cement in bulk in a 5. satisfactory manner it is necessary to protect the same from moisture and it is further necessary to provide for ready removal thereof from the bottom of the car in which it is contained. As cement or similar heavy material is removed from a car which is supported through the medium of springs, the car will rise due to the lightening of the load and accordingly it is necessary'to provide means permitting proper unloading irrespective of the upward movement of the car.

It is the broad object of the present invention to provide a railroadcar which may be readily loaded and discharged and which will be substantially water-tight to prevent injury to a material such as cement in bulk when the same is in transit. It is a further object of the invention to provide means whereby a suitable discharge may be effected.

Furthermore detailed objects'of the invention and their accomplishment will be apparent from the following description read in conjunction with the accompanying drawings, in which: I

Fig. 1 is a longitudinal section through one end of the improved car.

Fig. 2 a horizontal section through an end of the improved car. A

Fig. 3 is a vertical section through the cen-. ters of opposite'hoppers.

Fig. 4 is a detail section view showing the discharging means for the car,

The car comprises a longitudinal draft beam 2 running its full length, to the ends of which are secured suitable couplings 4 in the usual manner. The draft beam is mounted as indicated at 6 upon suitable-trucks (not shown) provided -with wheels 8. This mounting may be of theusual form in whichsprings are provided te take up the shocks incident to transportation. I

Suitably supported from the draft beam is the body proper of the car which comprises upright side walls 10 surmounted by a roof 12, the central portion of which is provided with openings 14 adapted for charging,

which openings are,.during transportation, covered by removable covers 16 which are adapted to be clamped down over the open-. ings to secure against the entrance of rain or A In the car shown there are eight of thesehoppers, four being arranged-on either side of the draft beam. Each hopper is of general pyramidal formation having inner walls 22, which walls 22 of opposite hoppers meet to form a ridge extending longitudinally of the car. As shown in Fig. 2, the walls ofthevarious hoppers are so arranged that the ridge formed by the junction of walls 22 is substantially continuous through the length of the body. t v

The outer walls of the hoppers are formed by sloping wall members 24 secured at their upper ends to the side walls 10. Between adjace nt hoppers, arranged longitudinally of the car, are walls 26, the adjacent ones of which meet to form transverse ridges extend-' ing crosswise of the car. The end walls of the end hoppers areformed by the sloping end walls 28 ofthe car which form 'continua- I tions, angular flanges 30 may be provided for securing the upper ortions of the walls to the sides of he car.

7 By the arrangement described, it will'be noted that the. car may be readily filled through .openings 16, each of which is disin approximate alignment with the posed hopper tions into the-hoppers, as shown in- Fig. 1.-

In order to properly brace the various secmembers of a transverse pair of hoppers and in a position directly above the ridge formed by the meeting upper edges of sides 22. By this means a charge of cement or the like en; teringthrouglli1 the openings may completely and evenly the car. pon opening-pf the bottoms of hoppers 20in a manner to be hereafter'described the cement is free to; flow completely through the hoppers from the car, since there are no horizontal platforms or the like within the car, all of the walls tapering toward some one of the hoppers.

Surrounding the bottom of each hopper 20, as shown in Fig. 4, is a suitable frame 32 within which is slidably mounted'a gate 34 arranged to move horizontally across the per and enclose the gate 34. In order to secure the cover in position a latch member 40 is adaped to be moved over the flange 42 of the frame where it may be secured by a pin passed transversely through suitable aligning holes 44 in the frame.

To secure a discharge of the car without permitting a loss of the contents or admixture thereof with. water in case of a very moist atmosphere or rain, a flexible tube 46 formed of duck or canvas may be provided. This tube is secured at its upper end to a frame 48 and at its lower end to a similar frame 52. The center portion-of the tube is held in expanded condition by means of a metallic ring or the like 50 .which prevents its collapse when in use. Frame 52 is secured to a plate 54, which may be detachably held upon the top of a conveyor box 56 by means of spring clamps 58. The upper end of the flexible tube 46 with the frame 48 is preferably made so as to be readily detached after an unloading operation is completed. N

As indicated in Fig. 4, when the car is full, the tube will occupy the position shown at 46', by reason of the fact that the,car at this time, being loaded, compresses the springs and the body is accordingly in a lower position. As discharge takes place through tube 46, the cement passes into the conveyor 56 and is moved to a suitable storage or mixing place by a screw conveyor or the like, 60. As the discharge proceeds, the body rises upon the springs and consequently tube 46 finally reaches the position indicated in full lines in Fig. 4. The utility of the flexible ,connectionwill accordingly be seen to reside .not only in the ease of handling 'it will be seen that there is provided a car in which none ofthe contents will be held so that the discharge would be incomplete. The advantages of having a. draft beam extending the complete length of the car are retained together with the accomplishment of.

complete discharge.

What I claim and desire to protect by Letters'Patent is:

1. A car comprising a frame including a 4 beam and extending to said openings, and the outer walls extending from the side walls of the body to the openings, the outer walls of the hoppers being inclined at larger angles to the horizontal than the inner walls of the hoppers whereby the openings are located adj acent the sides of the car body.

2. A'car comprising a frame including a longitudinally extending draft beam, a body mounted on said frame including side and endwalls, and hoppers extending downwardly on opposite sides of the draft beam, said hoppers having bottom discharge openings with closure means therefor and having inner and outer walls, the innerwalls of adjacent hoppers meeting in a ridge extending longitudinally of the car above the draft beam and extending to said openings, and the outer walls extending from the side walls of the body to the openings, the adjacent hoppers on each side of the car having end walls meeting intransverse ridges, the outer walls of the hoppers being inclined atlarger angles to the horizontal than the inner walls ofthe ing discharge openings with closure means therefor, the inner walls of adjacent hoppers meeting in a substantially central, longitudi-' nal ridge and extending to said openings, and the outer walls of'said hoppers being inclined at larger angles to thehorizontal than the inner walls whereby the discharge openings are located adjacent the sides of the car body.

In testimony of which invent-ion, I have hereunto set my hand, at Philadelphia, Pennsylvania, on this 11th day of October, 1928. MORRIS KIND.
