. bottoms to facilitate the dumping of the contents. v
Such cars at the present time are so constructed as to have bot-toms which are capable of a swinging movement, but this movement, because of the particular construction and due to-the given height-of the bottoms from the ground, is limited, so that the discharge opening formed is small. Hence the contents can only slowly befdischarged and when the pieces of coal, ore, or the like, are frozen together or for some other reason stick together, pounding and pushing are required to cause or hasten-the discharge. l
The principal object of my invention is to provide a construction whereby these drawbacks will be obviated.
With this and other objects in view, my invention consists in the novel construction, combination and arrangement of parts as will be. hereinafter more fully described and defined in the appended claims.
In the accompanying drawing in which similar reference characters denote corresponding parts, Fig. l is a side elevation; Fig. 2 a top plan view; Fig. 3 a bottom plan view as seen along line 33 of Fig. 1; Fig. 4 is an enlarged cross section on line 4L-4 of Fig. 2 and Fig] 5 is an enlarged cross section on line 5--5 of Fig. 2.
The car, as usual, is composed of a rectangular wheel base frame 10, walls 11, which at their lower ends are obliquely-cut away andare adapted to support. chutes 12 carried by the end walls (not shown). The
"' base frame 10 through centrally longitudinally extending bars 10 and cross bars 10 is divided into a number of sections, four in the present example, each section having a separate and independently movable bottom 13. There are two longitudinal bars 10' separating these sections laterally. These bars are parallel to one another and are spaced sufficiently far apart to accommodate between themselves in parallel arrangement,
longitudinally extending spindles 14, two on each side of the central cross bars 10 The central cross bags 10 are also spaced apart to' accommodate between themselves cross spindles 15, two on each side of the longitudinal line of the car. The longitudinal spindles 14 are supported in bearings 16 and 17 and intermediate bearings 18 and are formed each with two or more hook shaped members 19 adapted to engage the inner free edges of the movable bottoms 13. The opposite longitudinal edge of each bottom is formed with two or more upwardly projecting angular and bifurcated arms 20 formed with cross pivots 21. Projecting from the frame 1 10 upwardly are longitudinally grooved supports 22 adapted to rotatively engage said cross pivots 21, so that when the bottom 13 is swung downwardly on its pivot 21 it will, by reason of the elevated supporting points be permitted to swing clear of the tracks and the ground; and open to'its full extent, so that the contents can be completely dumped at once.
.The longitudinal spindles 14 are free to rotate in their bearings 16, 17 and 18, but means are provided to hold the same against rotation and the hooks 19 in engagement with the inner edges of the bottoms 13. These means comprise looped arms 23 preferably made of wire'or the like and pivotally connected to arms 24 projecting from the spindles 14 and stationary fingeis 25, projecting from the frame 10 serving to engage the loops 23 of said arms. Foldable look pins 26 fitting in holes 25 of the fingers 25 may serve to prevent the loops 23 from slipping off the fingers.
When the contents are to be dumped the looped arms are disengaged fromthe fingers 25 after the withdrawal of the lock pins, whereby the spindle 14 will be rotated and the locking member 19 released, permitting the bottom to swing downwardly under the load.
For the return of thebottoms into closed position, I employ the following contrivance:
The spindles 15 carry ratchet wheels 27 with which cooperate pawls 28 fulcrumed on the brackets or bearings 29 of the spindles. Fastened to and adapted to wind around these spindles are cables, ropes or the like 30, which are hooked to or otherwise attached to the bottoms as at 31. When the bottoms are in closed position. the cables lltl hll
(fil
are wound around the spindles, and the latter locked against rotation by the engagement of the pawls with the ratchet wheels. The outer ends of the spindles are formed to squares 15' for the application of cranks whereby the spindles can be..turned to raise the bottoms into closed position.
In order to prevent the material from falling into the spaces occupied by the spindles and obstructing the operation thereof, said spaces on the inside of the car are covered by hoods 32, 33 which are suitably fixed in position and the outer or upper faces of which may be made roof shaped, as shown, to act as chutes, so that when the material is dumped the pieces lying on the hoods will have the tendency to slide down and pass through the opened bottoms. The simplicity whereby the bottoms can be released and the arrangement of the hinges of the bottoms at a certain elevation in order that the bottoms when swung open will not strike the ground, are advantages rendering my construction very practicable. 'lhe grooves 22 of the supports 22 are open at their upper ends to permit the passage of the cross pins 21 into said grooves. Locking pins 3d may be used to secure the pivots in said grooves.
From the inside of the car the hinges of the bottoms are shielded by casings or hoods 35 having inwardly slanting tops 35.
What I claim is l. A car for coal or the like, having a laterally swinging sectional bottom whose fulcrunis are arranged at an elevationabove the base frame, freely rotatable spindles formed with means engaging said bottomin closed position and means operatively connected to said spindles and adapted to bedetachably connected to stationary parts of the car for locking said rotatable spindles in operative position.
2. A. car for coal or the like, having a laterally swinging sectional bottom whose fulcrums are arranged at an elevation above the base frame, a freely rotatable spindle formed with means engaging the said bottom in. closed position, and an arm pivotally connected to said spindle and capable of engaging a stationary part to lock said spindle in operative position.
3. in a car for coal or the like, a base frame having a plurality of laterally swin ing bottoms, each bottom being pivotally suspended at an elevation from said base frame, rotatable spindles arranged between adjoining bottoms and having means engaging the said bottoms in closed position, and arms on said spindles adapted to bedetachtaiarea ably connected to stationary parts of the car to hold said spindles inoperative posie tlon.
4C. In a car for coal or the like, an open base frame divided longitudinally and transversely into a number of sections, bottoms for said sections, each bottom being formed with upwardly projecting bifurcated arms carrying cross pins, upwardly projecting grooved supports on said base frame to rotatively bear said pins and form therewith hinges at an elevation from said base frame, freely rotatable members to engage said bottoms in closed position and means for holding said members in operative position.
5. In a car for coal or the like, an open base frame, divided longitudinally and transversely into several sections, swinging bottoms for said sections, rotatable spindles extending between the lateral sections and having means for engaging said bottoms in closed position, arms on said spindles adapt ed to be detachably connected to stationary parts of the car for locking said spindles in operative position and hoods inside the car to shield said spindles.
6. ln a car for coal or the like, an open base frame, a laterally swinging sectional bottom, rotatable hooks for engaging said bottom in closed position, an arm operatively connected to said hooks and adapted to be detachably connected to a stationary part of the car for locking said first hooks in operative position and a pawl and ratchet controlled spindle connected to said bottom and serving to raise said bottom into closed pos1- tion. I
7. In a car for coal or the like, an open base frame divided longitudinally and transversely into several sections, laterally and independently swinging bottoms for said sections, longitudinal spindles between the adjoining longitudinal edges of said sections, means on said spindles to engage said bottoms in closed position, arms on said spindles adapted to be detachably connected to stationary parts of the car for holding said. longitudinal spindles in operative position. manually operable cross spindles between the adjoining inner end edges of said sec tions, said cross spindles being connected to said bottoms to close said bottoms and hoods inside the car to shield said longitudinal and cross spindles.
