DUMP CAR.
Application filed September 8, 1923.
To all whom 'it may concern:
Be it known that I, JOSEPH H. SLAKER, a citizen of the United States, and a resident 0f Aurora, in the county of Kane and State of Illinois, have invented certain new and useful Improvements in Dump Cars, of which the following is a specication, reference being had to the accompanying drawings. v
This invention relates to side-dump cars of the type shown and described in Letters Patent N o. 1,357,251, dated November 2, 1920, granted upon the application of Jay B. Rhodes. The invention has for its objects to provide improved and more simple means than there shownfor operating the supporting struts to effect a tilting of the car bed; to provide improved means for securing to the rock-shafts that lie beneath the car bed the several arms that project radially from such shafts, and to improve generally the Construction and operation of` devices of this general character. That which I believe to Y be new is set forth in the claims.
In the drawings,
Fig. 1 is a transverse section through a dump car bed at a point approximating its longitudinal center and illustrating, in connection with the power. means by which a tilting of the car bed is effected, the improved means for securing the locking arms to their respective rock-shafts;
Fig. 2 is an enlarged detail beingav perspective view of one of the locking arms and illustrating the, means employed for connecting it to itsv rock-shaft; v
Fig. 3 1s a transverse section through the car bed taken near one'end thereof and' illus` trating the struts that support each side of the car, and also the improved" means through which said struts are moved when the car bed is to be tilted, the strut at ythe lright-hand side of the ligure and the means that act upon it being shown in the position they assume at the time the power means are in the position shown in Fig. l.;V
Fi etis a plan View of the means through' whic i the supporting struts are operated lto effect a tilting of the car bed, the struts beinin section; v
ig. `5 is a view similar to Fig. 3- but showing the parts in the position they assume when the car bed hasbeen tiltedand the power meansythat has caused the tilting has been returned to normal position; and
Serial No. 661,608.
`strut with which such member is connected.
Referring to the several figures of the drawings,-1O indicates a car bed pivoted centrally at different points, as atV 11, throughout its length to heavy brackets, such as shown at 12, that rise from `and are secured to an ordinary under-body that preferably comprises a pair of spaced-apart longitudinal I-beams 13. Near the longitudinal center of the car and on opposite sides, respectively. of the said beams 13 are located two cylinders 14k adapted to be supplied with compressed air, as usual, so as to force up alternatively the plungers 15 in said cylinders that carry the laterally-mov able plunger-rods 16, each plunger-rod hav ing pivotally connected to its upper end, as
`at 1S, a curved'bar 17 that at its other end is pivotally connected at 19 to a central support or bracket 2O carried by the beams 13, as shown in Fig. 1. The rounded head of each plunger-rod is adapted, when such rod is forced up, to engage with the recess 2l in the lower end of the lower member 22 of a thrust bar, the other member of which thrust bar is indicated by 23 and is pivoted to the car bed at 24,-the two members of each thrust bar being pivoted together at 25, and the thrust bar as a whole being held in proper position to be engaged by its coacting plunger-rod by a bar 26 secured in place at its inner end upon'the pivot 19 and being attached at its other end by a pivot 27 to the lower member 22 of the thrust bar. The construction and operation of the parts so far briefiy referred to are'in all substantial respects like the corresponding parts in the said Rhodes patent and it is therefore not deemed necessary to describe them more in detail.
28 indicates two rockshafts mounted in suitable bearings carried by the under-body, said shafts being arranged parallel with each other and on opposite sides, respectively, of the longitudinal center of the body. As in said patent there is secured upon each shaft so as to rock therewith an arm which by bearing at its free end against a member of the under-body will act to prevent rotation in one direction of the shaft to which it is attached, but by reason of the engagement with such arm of a la-tch pivotally mounted on-the adjacent curved bar 17 may be swung out of locking position when such bar is moved up. `Each of the said locking arms is indicated by 29 and the respective latches by 30. Both with respect to the manner of attachment to its roc-kshat and in its construction to adapt it tor engagement with its latch each ot these locking arms 29 differs from the corresponding part in the said Rhodes patent. In that patented construction each rock-shaft was square in cross-section, or at least that portion was so shaped that carried the locking arm. I avoid the necessity of squaring that portion of the cylindrical rock-shaft and of forming a Correspondingly-shaped eye in the locking arm by i'orming in one face of the locking arm a notch 31 (see F ig. 2) into which the cylindrical rock-shaft' fits, the Atwo parts being clamped together by a U-bolt 32 upon, the ends of which are screwed nuts 33. Relative rotation of the parts is prevented by a key 34. The free' latch to engage with and therefore is not only cheaper to construct but is a stronger construction than where such a pin was used, as was the case in said patented con struction.
Toward each end ot' the car and at equal distances from the transverse center thereof are employed, as in the said patent, two jointed or toggle-lever strut devices, each of which devices, as shown in Fig. 4, l pre- 'ter to make voit two spaced-apart sets of similar jointed members, the upper member of each set being indicated by 35 and the lower one by 36, the inner ends of the parts 35 and 36 being pivotally mounted on a heavy pin 37. The upper end ot each toggle member 35 is pivoted at 33 to the car bed and the lower end of each toggle member 36 is pivotally connected at 39 to the outer end of a bar 40, the other ends ot which bars 40 are pivotally attached at 41 to a portion of the under body-the construction being quite similar to that shown in the said patent. 1n that patented construction, however, there was employed a rigid locking bar for each strut device which at its outer end was pivotally attached to the strut at a point below the joint in the strut and at its inner end was connectedl to a rocking lever mounted on a pivot separatel from and in a higher plane than the said rock-shafts, and, through a system of links and levers interposed between the said rocking lever and the rock-shafts the turning of one of the rock-shafts would cause such a pull upon the proper one 'of the long locking bars connected with the struts as to break the toggle-like strut that such bar was connected with, so as to thereby effect a tilting of the car bed.` Ii have Vdevised a very much simpler arrangement of parts for accomplishing the supporting and breaking of each of the toggle-like struts.` In my improved construction the locking bar is itself tormedof two members jointed together to form. a toggle device, the outer and inner members being indicatedrespectively by 42 and .43 and the .pivot connect-` ing such parts together being indicated by 44. The `outer member 42 is' preferably formed of branches that diverge from the pivot 44, as shown in Fig. 4, the end porj tions 'of which are journaled upon the heavy pivot 37. The inner member43 o- .each toggle-like locking bar is journaled vupon the adjacent rock-shaft 2,8,the inner'end portion of suchv inner memberl extending past suchrock-shatt to a point closely adja cent to the other rocks'haft (see Figs. 3 and 4) when said locking barv is in vits lock.- ing position. As shown in Fig. 4 the outer members 42 of the two locking?barsV are so shaped as to position the inner 'membeis out cit' alinement with each other,'thusp'ro viding for the attachment 'to each rockshatt of an arm that willoverlietheprojecting inner end of thel lockingpbar ment ber 43 that is journaled upon thepther rockshaft. Each of these overlying armsV is indicated by 45, and, as best shownY in'li` ig. 6, it has a curved groove in its under face in which tits the cylindrical rock-shaft, the parts being held together by a Ll-hclt 46 embracing the'shaft and passing through the arm and nuts 47 screwed on the ends 'of the bolt. AsV in the case of the arms 29 that are carried by these same rock-shafts, akey', indicated by 4S, is employed to prevent're lative rotation between each arm45and'the shaft upon which it is mounted.
In Fig. l the plunger rod 16 at the left hand side of that figure is shown as having been raised suticiently to engageV with the jointed thrust bar atthat side of the car, such upward movement of that plunger rod having of course turned the curvedbar 17 that'is connected with it so as Jto-carry up its latch 30 and the locking arm29 that such latch engages. That locking'arm. being non-rotatably connected withits rockfshaft causes a turning of the rock-shaft` in clockwise direction as viewed in Fig. 1 with the result that the other arm y4,5 that islalso. aijiqxjed Vin likemanner to that rock-shaft is turned down and forced against the underlying projecting end portion of thelockingibar member 43 that is pivotally mounted on the other rock-shaft, such turning, ofcourse, Causing a breaking 0f the 'tegels-leiter deil-l ` to secure by Letters vice of which that said member 43 is apart, and necessarily also breaking the toggle-like strut device with which said other toggle device is connected, as shown in full lines at the right-hand side of Fig. 3. Such breaking of these toggle devices permits the tilting into dumping position of the car bed as shown in Fig. 5. In that ligure the arm 45 that had been rocked down as shown in Fig. 3 is shown as restored to normal horizontal position due to the retraction of the plunger and its piston that had been operated to elfect the tilting. The operation of the parts for effecting a tilting of the Car bed toward the opposite side will be obvious from the description given, and a description of the manner of effecting a righting of the bed is deemed unnecessary as it is fully set forth in the said Rhodes patent. The free end of each arm 43 is rounded as shown so as to move easily over the surface of the locking bar member 43 that it engages.
By my improvements I dispense with a considerable number of parts that were heretofore deemed necessary, as shown by said patent, for accomplishing the moving or flexing of the supporting struts and am able to apply with equal effectiveness and much more directness the power from one of the rock-shafts to the supporting strut device at the opposite side of the car.
What I claim as mly invention and desire atent, is-
1. A dump car comprising in combination a car bed, a support therefor with which said bed is pivotally connected to adapt it for tilting in opposite directions alternatively, a laterally-movable strut under the car bed near each side thereof, two parallel rock-shafts extending longitudinally of and beneath said bed, two locking bars pivotally mounted on said rock-shafts, respectively, and each connected with one of said struts, means carried 'by each rock-shaft adapted, when the rock-shaft is turned, to engage and turn the locking bar that is pivotally mounted on the other rock-shaft, and means for rocking either of said rock-shafts.
2. A dump car comprising in combination a car bed, a support therefor with which said bed is pivotally connected to adapt it for tilting in opposite directions alternatively, a toggle-lever strut under the car bed near each side thereof, two parallel rock-shafts extending longitudinally of and beneath said bed, a toggle-lever locking bar connected with each of said struts, the inner member of each of said locking bars being pivotally mounted on one of said rock-shafts and having its inner end portion projectingF toward the other rock-shaft, means carried by each rock-shaft for engaging the said projecting inner end portion of the locking bar that is pivotally mounted on the other rock-shaft, and means for rotating either of said rock-shafts. i
