IE'OUBING APPARATUS FOR HOT METAL.

Application filed March 12, 1917.

To all whom it may concern:

Be it known that I, EDGAR J. REILLY, a citizen of the United States, residing at Youngstown, Mahoning county, Ohio, have ul Pouring Apparatus for Hot Metal, of which the following is a full, clear, and exact description, reference being had to the accompanying rawings, forming part of this specification, in

10 which- Figure 1 is a side elevation of one form of apparatus embodying my invention.

Fig. 2 is a detail view, partly in section, and partly in side elevation, of a portion of 1, with the ladle in a partially tilted position.

Fig. 3 is a plan view of the apparatus shown in Fig. 1, and

Fig. f is a detail sectional view, on the 20 irregular line IV-IV of Fig. 3.

My invention has relation to apparatus for pouring hot metal, and more particularly to pouring stands in which a. ladle or other vessel is held while being emptied,

' hot metal in and around iron and steel mills and furnaces. These ladies are of various sizes and capacitles, being usually earned by overhead or upon ladle cars. Somesimply receive the metal from a furnace and transfer it into molds or other receptacles, without being themselves transported to any other point.

As heretofore constructed, the bearings traveling cranes,

35 upon the ladle which are used in the pouring operation have been sub ect to excessive wear, due to sliding of the bearings upon those parts of the pouring stands with which they contact. This wear is greatly augwhich accumulates upon these surfaces, and also by the impossibility of successful lubrication. Such wear is particularly objectionable on account of the difficulty and expense of replacing the and also on account of the time lost while the ladle is withdrawn from service for making the necessary repairs.

My invention provides a. pouring stand in which all sliding movement of the ladle bearing surfaces is eliminated, thereby eliminating the wear due to this cause. It also Specification of Letters Patent.

Serial No. 154,221.

provides a construction in which the wearmgt surfaces are protected from dirt and gr1 A further object of the invention is to provide contacting and wearing parts which are of slmple and inexpensive character, and which may be easily and quickly replaced between successive operations.

A still further object of my invention is to provide apparatus of this character by means of which a low pour may be obtained, with a minimum splashing of the metal as it is discharged from the ladle.

My invention will be best understood by reference to the accompanying drawings, in which I have shown a preferred embodiment thereof, and which will now be described, it being premised, however, that various changes can be made in the details of construction and arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings the numeral 2 designates a ladle having the trunnion wings 3 provided with laterally projecting trunnions 4: upon which the ladle may be supported in the usual manner on a ladle car, or which may be engaged by the hooks of a lifting crane.

5 designates a stand in which the ladle may be placed for pouring. It may either receive the hot metal from the furnace while on this stand, Or the ladle may be transferred to this stand from a ladle car, or may be moved thereto from the furnace by means of a crane. This stand may, in general, be of any suitable character and construction, and'may be either fixed as shown, or it may itself be carried on a car in a manner similar to that shown in the patent to- W'. W. McKelvey No. 1,021,5d3, of March 26, 1912.

Each of the trunnion wings 3 of the ladle is provided with another set of trunnions 6 at a lower level than the trunnions 4L, and at a point considerably to one side of the vertical center of the ladle. These trunnions preferably rest in open bearings 7 stand 5. Each trunnion wing is also formed with an upward extension 8 having the open laterally and downwardly facing bearingrecess 9 therein. 10 designates the usual pouring spout or nozzle of the ladle, and 12 indi cates any suitable trough or runner into which the contents of the ladle are to be discharged, and by which the hot metal is conveyed to the molds.

13 designate two fixed stands or supports placed on opposite sides of the trough or runner 12. Each of these stands or supports 13 is provided at its upper portion with movable bearing member, or cradle, 15 which is rigidly fixed to a pin or shaft 16 by a suitable fastening, such as the bolt 17. The ends of the pin or shaft 16 are provided with removable bush bearings 18 in the side legs of the stand, these bearings being removably secured in place by suitable means such as the set screws 19. Each movable bearing member or cradle 15 is formed with the intermediate portion 20 which forms a convexed bearing surface adapted to the concave bearingsurface of the recess 9, before described. Each of said members also preferably has the upwardly extending lip 21 adapted for contact with the hook portion 22 adjacent to the recess 9; and a downwardly extending lip or flange 23 adapted for contact with the trunnion wing at 24.

I also preferably provide each of the stands or supports 13 with an antifriction guard roller 25 which is mounted on a pin or shaft 26 supported in the lugs 27 of the stand or support. These rollers act as safeguards in that, if the ladle should happen to slip out of the bearing members or cradles, they will catch it.

The operation will be readily understood. In making a pour, the ladle is first tipped on the trunnions 6 to bring the bearing surfaces of the recesses 9 into contact with the bearing surfaces 20 of the bearing members or cradles of the stands or supports 18, as shown in Fig. 2. The ladle may be tipped in any suitable manner, as by engaging a crane hook with the lug 28 thereof. Further tipping movement of the ladle occurs on these bearings, and instead of there being any sliding movement at these bearing surfaces, the pins 16 will turn in their bush bearings 18. These bearings are protected from dirt and grit, and wear therein is reduced to a minimum. If it becomes necessary to remove and replace them, this can be readily and quickly done with very little loss of time.

It will be further noted that my invention provides all the advantages of a low-pour ladle which are present in structures such as that of the McKelvey patent above referred to.

I claim:

1. A pouring stand for ladles, having a tiltable bearing member mounted thereon for engagement with the lip portion of a ladle when the latter is tilted into engagement therewith, substantially as described.

2. In metal pouring apparatus, a pouring stand provided with a rotatable bearing member, and with a guard adjacent to said member, substantially as described.

3. In apparatus of the character described, the combination with a ladle having bearing surfaces at opposite sides of its upper portion, of fixed stands or supports adjacent to the ladle when in pouring position and having rotatable bearing members or cradles adapted for engagement with the bearing surfaces of the ladle when the latter is tipped into engagement with said members, substantially as described.
