The doors will thus be allowed to open for the discharge of the lad lifting links 6 at the corners of the container. The lines l3 are of such length as to act as 2. lim ing as shown in Fig. 3. On the discharge of the lading, the line 8 and the cables 3 are again drawn upward, closing the doors, and resulting in itation means to limit the lowering of the con tainer with respect to the level of the crane and an upward movement of the container after the drop doors have closed. This upward movement to the ground or floor line and to stop the down of the line 8 is continued until the container is ward movement of the container at and to pre vent it from descending'below a predetermined raised to transport position, during which the 10 dumping level. The lines 3 and 8 are not so lim 7 cables l3 and I6 are restored to an inactive and 10 ited in their downward movement, however, and slack condition and the support of the container through their action the opening and closing again fully transferred to line 8 and cables 3 so movements of the doors may be effected when that the empty container may be transported back to the container car from which it has been the container is in dumping position. removed or to another container car or other The operation is as follows: 15 Assuming that a material for use in an open point Where it may be loaded, if desired, with a commodity which is to be shipped from the plant. hearth furnace plant has been shipped in con From the foregoing description, taken in con tainers of the character described placed in a ' container car, such a car, indicated at l8, being nection with the drawings, the construction and mode of operation of my improved means for the 20 shown in Fig. 1, it will be understood that when crane handling of drop bottom containers will the loaded containers are placed on the car and rested on the floor thereof the weight of each be readily understood, and it will be seen that container serves to hold its drop doors, which the invention provides a simple, reliable and ef? cient means whereby a container may be raised, lie in contact with the car ?oor, in closed condi lowered and transported and its doors controlled 25 tion against escape of its lading, without the use of fastening means for holding the doors in such in operation by the single draft line of a single line crane, such as one of the character referred condition. Releasable fastening means for hold ing the doors closed may, however, be employed. to, allowing ready handling of such containers Assuming also that the individual containers are in establishments equipped with such cranes 30 to be removed from the car and transported to without changing the construction of the con 30 tainer, which may also be handled in the ordi some certain point or to different points in the plant and dumped, the crane l is employed for nary way by two line cranes. While the con this purpose. To this end the crane 1 with the struction of the means shown herein by way of slings applied thereto is brought into position exemp-li?cation for carrying the invention into practical effect is preferred, it is of course to be 35 so that the hooks of the slings may be engaged with the eyes of the door operating cables and understood that changes in the form, construc lifting links of one of the containers, the crane tion and arrangement of the parts may be made line 8 being suitably lowered to allow this to be within the scope of the appended claims, without done, the dead lines being of sunicient length to departing from the spirit or sacri?cing any of 40 40 permit the engagement of the safety hooks with the advantages of the invention. What I claim is:— the container lifting links 6. ‘The crane line 8 is 1. Hoisting means for use with a traveling then raised to lift the engaged container from the car I8. In this operation of lifting the con tainer to the necessary height to clear the car crane carriage having a single draft line, and a container having a body provided with lifting raise the container to transport level, the sling lines In connected with the spreader links at the corners thereof, a drop bottom and bar 9 on the initial part of the upward move ment of line 8 will draw upon the cables In to said hoisting means comprising a sling consist ing of a spreader, ?exible dead lines connecting said spreader on opposite sides of its center with the frame of the crane carriage, and sustaining 50 45 and draw the cables 3 taut, thus holding the doors 2 50 closed against the weight and escape of the lad operating lines connected with said drop bottom, ing and forming therethrough a lifting connec tion between the line 8 and the container I, whereby as the upward movement of the line 8 continues the container will be lifted from the 55 car to the elevated transport position shown by the suspended container in Fig. 1. This upward movement of the line 8 results in the slacking of lines connecting said spreader with the lifting links of the container, said dead and sustaining lines being of ?xed length rendered taut when the container is lowered to dumping position to sup port the container and to be slackened when the container is raised above such position to a the cables l3 and i6 which are inactive for con tainer suspending purposes so long as the con 60 tainer is suspended from the crane by the line ineffective to support the container, and a sec 8 at this transport level. The suspended con tainer may then be transported by the crane l to the point at which the lading is to be dumped, for example at a point for use in proximity to 65 an open hearth furnace front, as shown in Fig. 3. To effect the dumping of the lading the line 8 is then lowered to a level at which the limita tion cables or dead lines l3 and the sling cables I'S are straightened out or rendered taut, where 70 by the support of the container is transferred to these cables, thus holding the container from further downward movement so that under a continued downward movement of the line 8 the cables 3 will be free for downward movement in 75 their housings under the weight of the doors and higher transport position and thereby rendered ond sling comprising a spreader arranged at right angles to the ?rst-named spreader and con 60 nected with the draft line, and ?exible lines con necting said spreader with the drop door operat ing lines of the container for raising and lower ing the container between such dumping posi tion and higher transport position and operating 65 the drop doors when the container is supported in dumping position by the ?rst-named sling. 2. Hoisting means for use with a traveling crane bridge, a traveling crane carriage thereon having a single draft line, and a container hav ing a body, lifting links at the corners of said body, a drop bottom, and'operating lines con nected at their lower ends with said drop bot tom and provided at their upper ends with cou pling eyes, said hoisting means comprising a 3 2,111,162 sling consisting of a spreader of inverted trian gular form, ?exible dead lines connecting said spreader on opposite sides of its center with the frame of the crane carriage, sustaining lines con nected with the lifting links of the container, and a two-part detachable link connection between by rendered ine?ective to support the container, said sustaining line and the vertex portion of said spreader, said dead and sustaining lines be lowering the container between said dumping po sition and higher transport position and operat ing of ?xed length so as to be rendered taut 10 when the container is lowered to dumping po ing the drop‘ doors when the container is sup sition to support the container and to be slack ened when the container is raised above such po sition to a higher transport position and. there and a second sling comprising a spreader ar ranged at right angles to the ?rst~named spread er and connected with the draft line, and ?ex ible lines connecting said spreader with the eyes of the drop- door operating lines for raising and 9 ported in dumping position by the ?rst-named 10 sling.
