ing had to the accompanying drawings,

which are a part of this specification.

The invention relates to ladle-holders.

It frequently happens in the foundry that molds of different heights have to be poured and while it is customary to transport the;

ladle with the metal therein from the furnace to the molds by an overhead conveyer such as a traveling crane it is necessary in view of the varying heights of the molds to adjust the height of the ladle for pouring after it has been brought to the molds.

t is one of the objects of this invention to provide a ladle holder which permits; of the raising or lowering of the ladle carried by it to facilitate'the pouring of the metal from the ladle for molds of difierent heights.

Another object of the invention is to provide a ladle holder in which the ladle may he raised or lowered and adjustably secured in different positions.

The invention further designs to provide anew and improved form of ladle holder.

In the drawings, Figure. 1 is an elevae Lion of the device embodying the invention; Fig. Qis a section taken on the line 2-2 of 1. Fig. 3 is a section taken on the line of Fig. 1. Fig. 41- is a section taken on The invention comprises a frame A having vertical side members B and C and a transverse upper memberl). the lower ends of the members B and C having hooks E thereon adapted to be detachably secured on the handles F and G on the ladle H and 1118111153 are providedfor raising and lowering the frame A and consequently the ladle l whichis secured to it and for adjustably =ccuring said frame in different positions to wise or lower the ladle to facilitate the pouring of the metal from the ladle for molds of difierent heights.

I The frame A is adjustably secured on a tubular supporting member I which is adjustably secured at its upper end to a tubular support J fitting within it, said tubular support J carrying a hook K at its upper end which is'designedto be'detachably secured to an overhead means for conveying Specification of Letters Patent.

the ladle. The means for adjustably securmg the support I to the support J for eX- tending the length of the support for the holder comprises a'plurality of apertures p 111 the support P which register with apertures 7 n the support J adapted to receive a locking pin which extends therethrough' within the tubular support I. The tubular support It carries a'collar N' at its lower end secured theretoby a set screw 1?. and a block or a collar 0 fits upon the outside of the support I and rests upon the collar N. A verti-.

cally extending rack P is secured at one end to the collar 0 and'at its other end to a collar which is rigidly secured to the upper end of the support I by a set' screw g. Thus it will be noted that the collar Q and rack? serve to anchor the'collar O on the support 1 adjacent the lower end thereof.

The means for raising and lowering the frame A comprises an operating lever 10 keyed at one end to a shaft 11 whichis pivotally mounted in the collar 0 and a pair of arms or levers 12 which are also keyed to the shaft 11, the lever 10 and the'arms 12 connected to the shaft 11 forming a bell crank lever. The other ends of thearms 12 are pivotally and adjustably secured by a bolt 13 extending therethrough to one end of a pair of arms or levers 1d whiclrare pivotally secured at their other ends to a pin 15 which is pivotally secured in the transverse member D of the frame A. The pin 15 carriesa'n anti-friction roller 16 which is designed to operatively engage with the out side of the support I; the pin-15 being journaled inside

members

17 and 18 of the frame member D and the roller 16 being secured on the pin between these sides. The

arms 12 and 1 1 areprovided with a series- Patented Sept. 8, 1914:.

end and which is keyed to a pin 23 which is journaled in the sides 1! and 18 of the frame member D the pin 23 carrying a lever keyed thereto adjacent one side of the frame member D.

T he operation of the device is as follows: The ladle holder is hooked on to the overhead support or conveyor for instance the hook K may be secured to the cable of an overhead traveling crane and the ladle which is filled with molten metal is then. secured to the frame A by the hooks E which engage the handles and l of the ladle. In this condition the ladle is transported to the molds. if it be desired to vary the height of the ladle for pouring molds of different heights, the lever 10 is operated to either raise or lower the supporting frame A by means of the lift-linkage comprising the lever 10, arn s 172 and 1 1, for, it will be apparcut that when the lever 10 is moved down the arms 12 will move up and will exert an upward force on the arms 14; which being secured to the transverse member D of the frame will raise the frame, the roller 16 moving upwardly upon the support and the guide M moving upwardly within the tubular support I and when the desired position has been reached the locking dog 21 is thrown into engagement with the rack P by means of the lever in which position the handle G of the ladle H may be operated to tilt the ladle to pour the mold.

The invention thus exemplifies a portable ladle holder in which the ladle may be raised or lowered with respect thereto for pouring molds of different heights.

The invention is not to be restricted to the details herein set forth but may be *aried so as to be within the scope of the appendeo claims.
