HUGO RUDOLPH SLIVINSKI, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSGN- lVIENTS, TO INTERNATIONAL HARVESTER COMPANY, A CORPORATION OF NEW JERSEY.
LADLE CRANE.
Application filed September 20, 1918, Serial No. 254,993. Renewed March 211, 1920. SeriaI No. 368,31.
An object of the invention is to provide an arrangement of ladle and crane whereby an operator riding on the crane can easily manipulate both the ladle and the crane from the operators cab.
Another object is to provide a ladle crane ot this kind which can be readily reached from the ground.
Another object is to provide a ladle crane having these advantages and which at the saine time is simple and inexpensive to manufacture.
le'ferring now to the drawings,' i Figure 1 is a side elevation ot the ladle crane showin part ol the framework broken away; and
l `ig. 2 is a corresponding end elevation.
The 'trame oi the ladle crane consists, as shown, of a beam 10, depending side mem bers 11 and 12, the bottom member 13 and the cross braces 14 and 15.
rl`he ladle crane is preferably shown of the mono-rail type suspended from a single I-beain, the lower flange of the lbeam forming rails upon which the wheels 17 of the One of these wheels is propelled through a train of gears by the motor 18; this motor is controlled 'from the operators cab as will hereinafter be explained. The motor 18 receives current from a con- `veniently placed trolley wire 19througl1 the ll5 swivel about this pin so that the crane is able-to follow a curved track although the main 'trame beam 1s made long to allow a safe distance between the operators cageand the ladle.
i To the bottom of the depending member 1&2 is pivotally secured the bail ot the ladle 24. The ladle is mounted in the bail by means of trunnions 25 formed on the ring 25, Within which the ladle is detachably supported by engagement of its tapering `sides with the ring, one of the trunnions carrying a worm wheel which is operated by means of a worm through the flexible shaft 27 and by means of the hand wheel 28 which is located convenient to the seat 29 of the operators cab 30. Within easy reach of the operator is also placed the operating handle 31 of the controller 32. Both the operators cab and the ladle are placed near the ground so that it is a very easy matter 'for the operator to step in and out oit the cab.
This ladle .is designed particularly ior use in a foundry for carrying molten iron from the cupola to the smaller hand ladles which are used for pouring the molds.
lt will be seen from this description that l have produced a ladle crane which is very eliicient in service and which at the same time is very simple and inexpensive to build.
lVhile l have shown and described but a single form ol my invention it is to be understood that it is capable of many modifications. Changes therefore in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
l claim- 1. ln a travelling ladle-crane, the combil nation of a horizontal beam, trolley carriages swveled to the beam, means on the beam for propelling one of the carriages, fixed members depending from each end of the beam, a ladle pivotally suspended from the end of one member, an operators cage at the end of the other member, means connected to the ladle for tiltingit, and means Within the cage rfor controlling the carriage propelling means and for actuating1 the tiltmg means.
2. In a travelling ladle-crane, the conibnation of a horizontal beam, trolley carriagessvviveled to the beam, fixed members depending from each end of the beam, ladle pivotally suspended from the end of one member, an operator"s cage at the end ot ico y the other memher7 means connected to the ladle for tiltingrv it and actuating means therefor comprising a hand-Wheel Within the cage and a jointed shaft connecting the 5 hand-Wheel andy tilting means.
3. A ladle Crane comprising a ladle provided lWith trunnions, means for tiltably supporting the ladle on said trunnions, an operators cage fixed. on the support and means Within the cage and connected to one 10 of said trunnions for tilting the ladle.
In testimony whereof I alix my signature.
