SELF-UNLADING RECEPTACLE.
Specification of Letters Patent.
Patented May l, 1915.,
.application nea rune e, una. semi no. seines.
To all whom it may concern.'
Be it known that l, KARL BARTH, residing at Essen-on-the-Ruhr, Germany, a citizen of the German Empirdhave invented a certain new and useful lfmprovement in Self- Unloading Receptacles, of which the following is a specification.
The present invention relates to selig-unloading receptacles of theclass shown and described in. the (zo-.pending application, Serial No. 796272, hled Cctober 20, i913.
The object oi" this invention' is to provide a very simple construction to permit unloading in either' one or lthe other side of the receptacle.
ln the accompanying drawings is illustrated one embodiment of the present invention representing a self-unloading car., and Figure l shows a transverse section of the car in loading position; Fig. 2, a similar section orq the car in intermediate position during the unloading; Fig. 3, a similar section ot' the car after unloading to the right side and, F ig. 4, a section similar to that shown in Fig. l ot a car after unloading to the left side.
@n the bottom frame A ot the car are secured parallel to each other the two end walls A1. A pedestal bearing A2 is moreover securely mounted on the under trarne A at each oi,3 its front and rear ends. Two double armed levers C situated symmetrically on Yeach side of the middle longitudinal plane of the car are by means ot' journals c connected to each of the pedestal bearings d2 in which bearings rests a trough-run ning longitudinal shaft B provided with two securely fastened sectors 51. Illheselevers C rest with each of their inner ends and by the intermediary of rollers 02, on the sectors 1 respectively, when the car is in its loading position, see Fig. l. Cup-shaped bearings o4 are provided between the journals c1 and the rollers c2 on the levers C. The outwardly directed 'arms' c3 ot the leversC have been so constructed, that its center of gravity when they rest upon the sectors b1 is situated perpendicularly beneath the axes et' the journals c. ln the cup-shaped bearings o", the bottom D is supported by means of trunnions d1 when the car is in loading position, see Fig. l, these trunnions being secured on reinforced suspension plates d: ot the bottom D. ln order to prevent the bottom from tilting around the axes of the trunnions d, situated on the one or the other side of the car, when the latter is in loading position that is when all the levers C rest upon the sectors l; still other trunnions cl3 have been provided on the suspension plates d2 above the trunnions d1, these trunnions Z3 resting against projections a3 of the pedestal bearings A2. These projections are of such a shape that they only will prevent a tilting movement of the bottom when all of the levers C rest upon the sectors b1 as already described; but that they permit such a tilting movement when the levers on one side of the car have lost their support.
ln each pedestal bearing A2 are moreover provided recesses at into which the trunnionsl d* may tall on the unloading movement. Lastly other recesses a are also provided on each pedestal bearing A2 for the trunnions da. These recesses a are situated so that the trunnions d3 are only at a short distance trom them when the ltrunnions d1, situated .on the same side, have y fallen into their recesses at, while the trunnions (Z1, situated on the opposute side, rest in the bearings c4, see lhg. 2. Blocks a are secured on the underframe A for supporting the bottom inthe unloading position.
ln the loading position of the car, the side walls F which are provided with handles f1, are supported at their upper'. ends on journals f2 in bearings a? which are open at the top and provided on the sides of 'the end walls lh-and at their lower end by means of inclined angles if on rollers di* which are carried in hearings on extensions d of the bottom D. The journals f2 are guided by means of links G which are connected with the end walls A1.
lli the car is to be unloaded toward one side, say for instance to the right, the shaft E has to be turned in the direction oi the arrow fr, see Fig. l. The sectors will then get out of the path of the levers C situated to the right, which then lose their support and swing away in the direction ot' the arrow y, actuated by the weight of the bottom and the load, transmitted through the trunnions cl. The trunnions al situated to the left remain in their bearings c4, see Fig. 2, so that the bottom D, during its subsequent tilting movement, turns around the axes of these trunnions, and that the rollers d* situated to the right, leave the bearings formed by the inclined angles f2 of the right hand side wall F. lThe trunnions d situated to the right now slide out of their bearings c" and fall into the recesses a, see Fig. 2. Simultaneously the trunnions da situated to the left get out of reach of the corresponding projections a3, .and the trunnions d3 situated to the right arrive into the p0- sition adjacent to the corrgsponding recesses ai'. The left hand side wall F will be raised by the bottom, the journals f2 leaving the bearings c, while the right hand side wall remains' suspended with its journals f in the bearings a7. As soon as thefafiglit hand trunnions d1 have fallen into the recesses a, the bottom D tilts still further, actuated by the load, and it now turns around the axes of the trunnions d1 which have fallen into the recessesa.. Simultaneously the left hand trunnionsd* raise tlieniselves from the bearings c", see Fig. 3. In this manner the bottom finally arrives in the unloading position, sce Fig. il. wherein the trunnions d are resting in the recesses w" and the bottom D simultaneously is su )ported by the blocks a.
A ter finishing the unloading, the raised side wall F is drawn downward by means of the handles f1 until the journals f2 have entered the bearings a". At the same time the bottom D swings out of its unloading position, see Fig. 3, back into the position shown in Fig. 1, while it turns first around the axes of the right hand trunnions d1 and thereupon, after the left hand trunnions d1 have again entered the bearings c, around the axes of the latter. At the same time the right hand levers C return automatically into their osition shown in Fig. 1 as a consequence o? the above described construction of the lever arms c3. The sectors b1 have` now to be returned to their middle position. The bottom is then secure. If the car is to be unloaded toward the other side, that is t0- ward the left,l the sectors b1 have to be turned into the opposite direction to the arrow a'. 'lhe operation, compare Fig. 4, corresponds completely to the one described and needs therefore not be further entered upon.
