3 Claims.

This invention relates to transporting equipment for molten metal used in foundry plants, and this application is a division of an appli- Divided and this application May 26, 443,794

cation for United States patent on Foundry plainstsi flied by me July 9, 1941, Serial Number 40 The principal objects of the invention are to provide equipment which may be manufactured at a low cost but which is comparatively safe in use, and equipment including ladies which may be compactly stored and transported when not being used for filling molds, and detachable bails and operating or guiding handles which may be placed in operative relation to the ladies when their use is required. Thus a ladle may receive molten metal at the melting furnace and be moved on a conveyor in rather restricted quarters, and equipped with a bail and guiding handle means at or adjacent the pouring station for lifting and guiding the ladle to a position over the sprue holes or gates of the mold.

Other objects and advantages of the invention will appear in the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing- Figure 1 is a side elevation of transporting equipment constructed according to the present invention, a part being broken away and shown in section to illustrate details.

Figure 2 is an end elevation oi. the same.

Figure 3 is a plan of the detachable handle or guiding means.

Figure 4 is a side elevation of an eye part of the bail.

Figure 5 is a vertical section on the line 5-5 of Figure 4.

Figure 8 is a side elevation of a bar forming a part of the bail.

b fligure 7 is a side elevation of an arm of the Figure 8 is an end elevation of the arm.

The equipment comprises a ladle 9, a bail l0 and handle means il detachable with respect thereto, and means I! for releasably holding the handle means on the ladle.

The ladle is preferably, altho not necessarily, of the type shown in my co-pending application for United States patent filed May 20, 1942, Serial Number 443,795, which is adapted to permit the molten metal to flow from the bottom of the ladle. It includes an inverted frusto-conicai wall portion I3 and diametrically disposed laterally extending trunnions ll each having a reing a body part it and a head ll. These trunnions have a dual purpose-to cooperate with the detachable bail and to support the means it, as shown in Figures 1 and 2.

The ball is preferably made mainly of stock or easily procurable material such as a ring it, horizontal bars I9, bolts 20 having nuts 2!, and bolts 22 having nuts 23. The ring I? has a segmental spacer 24 welded to it, as shown in Figures 4 and 5, to fill approximately two-thirds of the opening of the ring, leaving an eye 25 above the spacer for a hook 26 of hoist mechanism, not shown in the drawing. To accommodate the shanks of bolts 20, used to secure the ring is and spacer 24 to the central portions of the bars i8, the bars are provided with transverse openings 21 and the spacer 24 with transverse openings 28. This assembly constitutes a yoke 29 to the end portions of which are plvotaily connected arms 30, preferably arcuate in shape, so they may be swung into position and connected to the trunnions N, or folded inwardly beneath the ring l8 to render the bail compact when being stored'or transported. Each arm is preferably made to comprise a body part 3i and a lower terminal portion 32. The body part is preferably of channel shape comprising a. web 33 and flanges 34. The upper ends of the flanges are provided with aligned openings 35 for the shanks of bolts 22, which latter are accommodated in aligned openings 36 in the end portions of bars ll. Each terminal portion 32 has a keyhole slot 31, the upper portion 38 of which is of a size to freely receive the head I1 and the lower restricted portion 39 to snugly receive the reduced portion I! of its respective trunnion it.

Referring now to the handle means ii, it comprises a ring it made to snugly engage the tapered wall It of the ladle, and diametrically disposed lateral arms ti extending therefrom, provided with hand grip portions 42. The ring 40 is preferably of inverted frustc-conical shape, the inner taper 48 corresponding to the taper of wall portion it somewhat spaced below the trunnions I 4 and above the bottom of the ladle,

so as to have surface to surface contact with duced portion i5 intermediate its ends, provid- 68 the ladle when the ring is raised into contact with same and so as to lit in a horizontal position symmetrically with respect to the axis or the ladle.

The means I! in the example shown comprises lengths of chains 44 preferably having rings or handles 45 at their end portions, the other ends being secured as at 48 to the trunnions I. When the handle means ii is in place on the ladle, intermediate portions of the chains may be quickly wrapped around the arms ll to hold the handle means I i in place.

As an example of use or the transporting equipment for molten metal, the ladies with the bails and handle means detached, may be charged.

at the melting furnace and moved on any suitable conveyor to the pouring station, where they may be equipped with bails l0, lifted and handle means ll applied. At the pouring station they may be used to assist in placing the ladies over the molds, and when empty, the balls and handle means may be detached and the ladies returned to the melting furnace on a conveyor to be recharged, or to storage space it no longer needed for that particular casting operation.

I claim:

I i. In transporting equipment for molten metal, the combination of a ladle provided with oppositely extending, laterally disposed trunnions, and handle means below said trunnions, detachably carried by the ladle, including a body portion embracing the wall of the ladle, op-

positely extending laterally disposed arms on said body provided with enlarged hand grip portions at their free ends, and flexible members carried by said trunnions with the intermediate portions thereof adapted to be wrapped around said arms between said body portions and hand grip portions, to hold said body in embracing relation to the ladle with the free ends of said flexible members depend ing from said arms.

2. In transporting equipment for molten metal, the combination of a ladle provided with oppositely extending, laterally disposed trunnions, and a detachable bail for the ladle including a yoke comprising a pair of paralleling bars, a spacer between with the intermediate portions of said bars, provided with a segmental portion, a ring, of less thickness than said spacer, extending about the periphery of the segmental portion of said spacer and above said spacer, and means securing said bars to said spacer, said ball also including a pair of arms, depending from opposite ends of said bars, provided with means at their lower ends for detachable connection with said trunnions.

3. In transporting equipment for molten metal, the combination of a ladle provided with oppositely extending, laterally disposed trunnions; a bail for th ladle pivotally connected to said 20 trunnions; handle means including a body portion detachably embracing the wall of the ladle below said trunnions, and oppositely extending, laterally disposed arms carried by said body portion, said arms located one below each oi said as trunnions; and means detachably suspending said handle means from said trunnions, including a chain for each companion trunnion and arm, each chain having its upper end portion secured to its respective trunnion and its inter- 30 mediate portion wrapped about its respective arm, with a free end portion of the chain de-
