Figs. 6 and 7 are cross-sec prevention of bodily,separation-between the tank tional views corresponding to lines 66 and 1! and; frame andalso to theprevention of rotation of Fig. l; and Figs. 8, 9, and 10 are cross-sectional Ofthe tank. In the present embodiment I have 50 detail views showing a preferred means of PTO-7' illustrated meanscooperating to this end, such viding for longitudinal yielding under shock cormeans participating to some extent in both funcresponding to the lines 8,-8, 9-9 and l0-Iil retions. In Fig. 3 {have shown the yoke l3 as spectively of the several views. Y j provided abovethe with clamping members 5 5 Describing by reference the parts shown in it movablebysuitable adjustingelements such transportation of bulk materials having imllpthese pintles being flexibly connected by 25 as the screws 15 to secure or release the tank as may be desired. 7
Further to prevent rotation and to absorb and transmit the longitudinal shock or thrust from the tank to the supporting frame I have shown .a second expedient comprising a radially projecting metal block 20 fastened to the tank exterior and rotatable between projecting portions of a slidable block 23, the block 23 being held by multiple spring's'2l midway betwee nitwo fixed blocks 5-2 I, rigidly secured to the'frame or platform. I have shown the block 20 as made hollow to save weight. Interposed at each end of the block 20 between it and the adjacent block 23 is a transverse wedge-member 22 held in place in any simple and suitable manner, such as'by means-of a nut 24 screwed on athreaded extension 25 of my sufliciently throughout the tank, as to require said wedge. Suitable washers or spacers 26 may be employed in cooperation with these nuts as will benunderstood by those skilled inthe art. The block, 23 here'takesthe'form of ':a transversely recessed member, longitudinally slidable along the top of the sill 4 between guides 29, and having abutment portions at its ends which the wedges 22 engage; When these wedges are in place the tank or container not only prevented from turning, by the action of the guides 29, but is also held yieldingly by the springs which in the case of an impactbetween different cars absorb the inertia of the loaded container. In the case of two such cars each containing a load of fifty tons the longitudinal strain produced when one of these cars moving'comes into'endwisef'contact with the other of these cars at rest, according to the degree of speed and care ordinarily encountered in railroad yard andswitching practice, is a very substantial fi ure. I Carried by the platform 2 at the end of the tank is astaltionary hopper 36 here. shown as supported on fourlegs 31 and'embracing a spout 34 projecting from the "center of the end .of the tank so'as to permit its rotation but prevent leakage of the material. The hopper: is'made slightly funnel shaped at its bottom 39 and is so constructed as to permit the attachment within the opening 38 of any suitable means (not shownlof conveying the material away during the unloading operation. Blades 32 fixed interiorly of the tank are so made as to'lift the material when the tank is rotated about its longitudinal axis anddisv charge it through the opening33 into thehopper. During transit'the spout '34 issealed shut byf a removable plate 35 held by any suitable means, the arrangement here shown consistingof nuts and bolts. Access to this closure p1ate'35 through the hopper maybe had by means of a door 3| which is hinged to the exterior of said hopper. The blades 32 extend to the wall of the tank and are so shaped and inclined as to liftand feed the contents through the spout 34 as the tank is revolved in the appropriate direction.
The interior of thetank is provided'throughout its length with one or more helical blades 40, spiraled in such direction that upon rotation of the tank in the'direction to discharge its contents through the discharge hopper said contents are moved toward the discharge hopper from the opposite end of thetank. At' the discharge end of the car these' 'blades 40 terminate at or'riear the zone definedby the blades 32. In Fig. l, for purpose of clarity, I have shown only one blade; in Fig. 2, I have shown two helical blades, and in Fig. 6, I have shown three blades.
Any suitable or convenient expedient may be employed to rotate the tank; the preferred expedient being to furnish the same with a circumferential sprocket 42 operatively engaged by a chain 43 meshing with a cooperating sprocket 44 which is driven by an electric motor 45 (or other suitable power source) carried by the platform 2 (or otherwise) and working through a speed-reduction gear-set 46. An electric motor is, of course, applicable only under conditions where electric power is available at the unloading station, and sometimes also at the loading station, but it is'obvious that with only a small change in construction the device can be arranged for operation by steam, gasoline. air or other power.
The procedure of filling the car depends to some extent upon the nature of the materials. Sometimes some materials, like cement when properly aerated, will of their own nature flow theqopening of only a single aperture 48. But in the case of some materials a plurality of apertures 48 are preferably employed for the introduction of the material. In case a full load is not obtained after such measures the covers may be'returned to'the loading apertures and the car rotated in one direction or the other, thus spreading the load lengthwise and making possible thej'addition of a further quantity'of material.
I have shown the end opposite the discharge hopper as provided with a manholerhaving a removable manhole-cover 41 to facilitate cleaning, inspection, and repairing.
In order to unload the tank, the car is so positioned as to allow the introduction into the opening 38 of, a screw conveyor, belt conveyor, orany other suitable means of conveyance. The closure 35 and the wedges 22 are then removed and the tank rotated m such direction as will move the material toward the discharge end ofthe tank. Inthe case of materials which tend to pack or solidify in transit the first revolutionof the tank is the most diflicult butgenerally results in a substantial breaking up of the load, after which the continued rotation not only moves the material to the outlet but also keeps it pulverized and prevents it from caking or blocking the outlets as oftentimes happens with a container which is stationary during evacuation.
It will be'understood that while I have de scribed my invention in detail and pointed out those constructions which seem to me most satisfactory for all around use, there are conditions existing in the specific arts which require modifications from the specific constructions and designs here shown, and I do not limit myself in any wise except as recited in my several claims which I desire may be construed each according to its own limitations and independently of limitationscontained in other claims.
