ADJUSTABLE LADLE HOLDER.

Application filed January 3, 1928.

This invention relates to improvements in adjustable ladle holders.

' It is one of the objects of this invention to provide an adjustable ladle holder in, which the supporting rod extending from the bail may be readily removed from the frame, and a supporting rod with a different type of bail, or with a single hook thereon substituted in its place.

It is a further object of this invention to provide an adjustable ladle holder in which the bail for holding the ladle may be pivoted to such an angle with respect to the frame, that the operator will have room to stand be tween the handle for tilting the ladle and the handle for adjusting its height, and readily operate one handle with each hand.

It is a further object of this invention to provide an adjustable ladle holder which has simplified mechanism for raising and lowering the ladle. V

It is a further object of this invention to provide an adjustable ladle holder in which the bail may be pivoted laterally during pouring so that several molds in a given are may be poured without moving the whole device.

It is a further object of this invention to providean adjustable ladle holder in which the supporting rod extending from the bail may be adjusted as to its normal height.

It is a further object of this invention to provide an adjustable ladle holder which is simple in construction and operation, and well adapted for the purpose described.

With the above and other objects in view, the invention consistsof the improved adj usts able ladle holder and all its parts and combinations as set forth .in the claims and all equivalents thereof.

In the accompanying drawing in which the same reference charactersdesignate the same parts in all of the views:

Fig. 1 is a front elevation of the improved adjustable ladle holder;

Fig. 2 is an edge view thereof; Fig. 3 is a fragmentary sectional view taken on line 33 of Fig. 2;

Fig. 4 is a sectional view taken on line 44 of Fig. 2;

' Fig. 5 is a sectional view taken on line 55 of Fig. 2; and

Fig. 6 is a view showing a substituted form of supporting rod having a single hook, in place of the rod with the bail secured thereto Serial No. 244,298.

as in Fig. 1, parts being broken away and parts being shown in section.

Referring to the drawing the device comprises'a pair of spring supporting rods 10, having an upper connecting plate 11 and a lower connecting plate 12. The upper connecting plate has extending therefrom a swivelled hook 13 which provides means for attaching the device to an overhead travelling crane (not shown). The lower connecting plate is formed with a medial opening 14. On each supporting rod is a coiled spring 15, the upper ends of which are engaged by a slidable member 16. The slidable member is provided with openings for receiving the rods 10, and with a medial opening for the end of a tubular frame member 17. The member 17 is provided with apertures 18 for adjustably connecting the member 17 to the slidable memher by a bolt 19. The latter bolt may be passed through any one of the apertures according to the height adjustment desired. The tubular member 17 also is slidably positioned in the opening 14 of the connecting plate 12. A guide member 20 having openings21 and 22 therein, is clam'pingly secured to the tubular frame member 17 by a clamping bolt and nut 23, the bolt extending through openings in lugs 24. On the lower end of the tubular frame member a lower guide memher-25 is secured. The-member 25 has an opening 26 for the frame member and an opening 27 in line with the opening 22 in the upper guide member. Theguide member 25 is held against downward movement on the frame member 17 by a collar 28 havinga set screw 29. .A bail supporting rod 30 is slidable-in the openingsv 22 and 27 of the guide members. The upper portion of the member 30 has a plurality of apertures 31, at any one of; which the collar 32 may be secured by means of the bolt 33. Below the collar 32is a. collar 34 having a set screw 35. Pivotally connected to a shaft in'an extension of the collar 34 are the ends of links 36. The other ends of the links are pivoted to one end of lever members 37 and 37. The lever member 37 is formed with a medial opening 38 and with a tubular handle receiving portion 39, and a tubular pawlreceiving portion 40. A shaft 41 extends through the guide member 25 and extends through the opening 38 in the lever member 37 and through an opening in the lever member 37', having a keyed connection therewith. A ratchet wheel 42 is formed as an integral part of the guide member 25. The ratchet wheel is engaged by a pawl 43 which is slidable in the tubular portion 40. The pawl is operated by a hand clasp 44 on the lever handle 45.

Welded or otherwise secured to the end of the supporting rod is a bail 46 having hookshaped end portions for receiving extensions 47 of the yoke 48. One of the extensions is bent to form a handle'49 for tilting the ladle The ladle may he maintained in upright A ladle of molten metal is positioned in the bail, and the device is then carried by means of an overhead crane to the molds which are to be filled. If it is desired to raise the ladle, the handle 45 is depressed, the pawl slipping over the teeth of the ratchet wheel 42. This causes the link 36 to push upwardly on the collar 34. The latter being firmly held by its engagement with the collar 32 will cause the supporting rod 30 to slide upwardly, carrying the bail and ladle with it. To lower the ladle, the hand clasp 44 is depressed to release the pawl. The handle is then allowed to raise upwardly until the ladle is in the proper position, when the pawl is released to hold the parts against further movement. When the proper height has been found, the latch 51 is disengaged and the handle 49 manipulated to tilt the ladle. As the metal is poured, there will be less weight upon the springs 15, and the ladle will be automatically raised an amount proportional to the amount of metal which has been emptied from the ladle, to maintain the ladle spout in the proper position for pouring. V

An important and novel feature'of the invention lies in the ability to swivel the ladle to anydesired angle with respect to the'frame. This is desirablcto allow enough'room between the handles 45 and 49 for the operator to stand. When thus positioned, he can readily operate one lever with each hand. This adjustment is readily accomplished by loosenin theset screw 35 on the collar 34, and swivelling the rod 30 until the ladle is at the proper angle. Furthermore, by loosening the set screw, the ladlemay be swiveled to pour several molds in a given are without moving the whole device. r 1

Another important feature is the removability of the rod 30. This is accomplished by removing the bolt 33, in the collar 32 and loosening the set screw 35 in the collar 34. The rod 30 may then be entirely withdrawn, and a rod such as is shown in Fig. 6 may be substituted in its place.

' An adjustment in the normal height of the rod 30 may also be accomplished by changing the position of the bolt 33 of the collar 34. Any one of the apertures 31 may be used.

From the foregoing description it may be seen that the improved adjustable ladle holder is simple in construction and operation, and well adapted forthe purpose described. i
