LADLE FOR MOLTEN METAL.

To all whom it may concern.-

Be it known that I, GUSTAV A. I-IAssEL, of McKeesport, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ladles for Molten Metal, of which the following is a specification.

The object of my invention is to provide a new and improved ladle for molten metal and to this end my invention consists of a ladle, having the novel features of construction and the combination of parts all as fully herein.- after described and claimed.

In the accompanying drawing, which illustrates an application of my invention Figure 1 is a part front elevational view and a part sectional view of a ladle constructed in accordance with my invention; Fig. 2 a part side elevational view and a part sectional view; and Fig. 3 a detailed sectional view taken on line 33 of Fig. 2.

Referring to the drawing the ladle 1, as illustrated and as preferred, is made of an integral cast-steel structure embodying trunnions 2, radial ribs 3 and annular strengthening ribs 4. In addition to these parts I provide around the top of the ladle an inwardly extending flange 5. The function of the flange 5 is to protect the brick-work or other suitable lining 6. The ladle is also formed with a bottom pouring opening 7 formed in the bottom of the ladle. An annular bead 8 surrounds the opening 7. The ladle is also formed with a top pouring lip 9 .and with lugs or eyes 10 near the bottom of the ladle.

1 1 designates a bail having end portions 12 engaging with the respective trunnions 2. The bail is engaged by forked latches 13, located at the upper end of the ladle and secured thereto by bolts 14 which latter are adapted to be passed through apertured lugs 15 preferably formed integral with the ladle.

*The ladle illustrated is designed to contain a large quantity of molten metal and I desire to call particular attention to the fact that the ladle proper comprising all the parts above mentioned with the exception of the bail, the latches 13 and the bolts 14 are made in one integral structure and not built up of numerous parts as, so far as I am aware, has heretofore been the practice. The advantages in providing a ladle formed of a single cast-steel structure over a built up ladle will be readily appreciated by those skilled in the art.

Specification of Letters Patent.

Application filed June 27, 1907.

Patented June 23, 1908.

Serial No. 381,010.

In the ladle illustrated I have shown strengthening bands 16 and 17,- the sidebands 16 extending downwardly from the trunnions and bolted to the bottom-band 17 The bottom-band 17 is riveted to the bottom of the ladle. These bands, however, do not constitute an essential feature of my invention and may be entirely dispensed with.

Another characteristic and important feature of the present invention is the stopperrod actuating and adjusting mechanism.

18 designates a stopper-rod which is moved vertically within the ladle by an operating lever 19. b As illustrated, lever 19 is con nected with a slide 20 by means of arm 21. Slide 20 is provided with a groove 22 and is adapted to slide in a guide-way 23 which latter is secured to the exterior of the ladle as clearly shown by the drawing. The upper end of the slide 20 is provided with an outwardly projecting plate-member 24 having a curved contacting or bearing-member 25. In addition to the member 25 said plate 24 is provided with bolt receiving-openings 26.

27 is a lock-nut extending into the groove 22 and is designed to lock the slide in the desired position in its guide-way 23.

Located directly opposite the member 24 of the slide I employ a member 28 compris ing a body-portion 29 formed with a tapering opening 30 extending through said body and adapted to receive a tapering rod 31. Rod 31 is connected with the stopper-rod by means of a rod 32. Member 28 is provided with a plate-member 33 corresponding to the plate 24 and is formed with a recess or socket 34 adapted to receive the rounded bearingmember 25. Plate 33 is also provided with bolt holes 35 which are adapted to receive bolts 36. Bolts 36 extend through the holes 35 of plate 33 and through the holes of plate 24 as clearly shown by Fig. 3. Rod 31 is formed with key-ways 37 adapted to receive a key 38.

By means of the adjusting mechanism just described the stopper-rod may be moved laterally within the ladle to cause thestopper to register with the pouring-hole in the bottom of the ladle. This is accomplished after the stopper-rod is lowered and locked by simply turning the nuts 39 on the adjusting-bolts 36. The means above described for adjusting the stopper rod are of such a character that the rod will be held firmly in any position to which it may be adjusted, and the clamping bolts for joining the two adjusting members serve to perform merely the function of holding such parts together, the rod itself or its connecting rod 31 being independently held and supported in the member 28 by means of a key-way and key.

What I claim is:

1. A ladle for molten metal having an integral cast steel body formed with integral trunnions and having integral ribs extending radially from the trunnions to the body, whereby the strain on the trunnions is resisted in all directions.

,2. In combination with a ladle for molten metal having a pouring opening in its bottom, of a stopper rod, means for laterally adjusting the rod relatively to the pouring opening comprising a member carried by the ladle, a supporting member having a ball and socket connection with the ladle member and clamping bolts on either side of said ball and socket connection and a connecting member between the ball and socket device and the stopper rod.

3. The combination with a ladle for molten metal having a pouring opening in its bottom, of a stopper rod, means for laterally adjusting the rod comprising a slide mounted on the exterior of the ladle and provided with a rounded bearing member, a socket member adapted to receive the rounded member, adjustable clamping bolts on either side of the members and joinin the same, whereby the socket member is held firmly in any adjusted position, said socket member having a bearing for a rod and means connecting said rod with the stopper rod.

4. The combinationwith a ladle for molten metal having a pouring opening in its bottom, of a stopper rod, a rod supporting member having means to engage and hold the rod from rotation and against vertical movement, a rounded member mounted on the ladle and adapted to enter a socket in said supporting member and adjustable clamping bolts independent of the rod-holding means for fixing said supporting member in adjusted position. i

In testimony whereof I ailix my in presence of two witnesses.
