APPARATUS FOR.HANDLING CONTAINERS OF LIQUIDS.

Specification of Letters Patent.

Patented Oct. 5, 192

Application filed December 20, 1919. Serial No. 346,213.

To all whom it may concern Be it known that I, EDWIN BEARDSLEY, a citizen of the United States, residing at Cheshire, county of New Haven, State of Connecticut, have invented a certain new and useful Improvement in Apparatus for Handling Containers of Liquids, of which the following is a full, clear, and exact descrip tion.

My invention relates to apparatus for handling containers of liquids and more particularly containers of molten metal, such as melting furnaces, crucibles, ladles and the like, which have to be tilted to pour out their contents, and has for its object to provide means for securing the accurate control of the motions of the container when being moved, and particularly when being tilted to pour contents into molds or other receptacles where it is desired to have the pouring lip or spout close to the receptacle during the pouring operation so that the container, while being tilted, rotates around a predetermined aXis passing near the lip of the pouring spout or orifice without requiring any actual support or trunnion at or near its axis of rotation.

The following is a description of an embodiment of my invention, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of an apparatus embodying my invention;

Fig. 2 is a front View of the same;

Fig. 3 is a side elevation showing position of the parts when the container has been tilted through an angle of 90.

Figs. 4, 5 and 6 show a modification.

Fig.4 is a side elevation of the modification;

Fig. 5 is a front elevation of the same, and.

Fig. 6 is a side elevation with the parts in the position they assume when the container is tilted.

Referring more particularly to the drawings, 1,1 are beams supporting tracks for a bridge-crane 2 for conveying the container to the receptacles A into which the metal is to be poured. 8 is a trolley on the bridgecrane which provides for movementin a crosswise direction if desired. This trolley carries drums 4, 4 to which are connected cables 5, 5, the lower ends of which are connected to bars 6, 6, through cross bars 11,

11. The rear ends of these bars 6, 6 slant downwardly. The drums 4, 4 can be operated in the ordinary manner to raise or lower both ends of the bars 6, 6 simultaneously, or to raise or lower their rear ends while their front ends remain stationary. The bridge-crane is the ordinary form of bridge-crane having independently operated cable drums 4, 4', being shown diagrammatically in Fig. 1. Depending from the trolley are two vertical guide-supporting members 7, 7, each having two guiding members 8, 8, having between them a vertically extending opening 9. The forward ends of the bars 6, 6 are provided with rollers 10, 10, which are mounted on the cross bar 11 and adapted to enter the openings 9 and move therein to the position shown in Fig. 1. The cables 5, 5 are connected to the rear ends of the bars 6, 6. Depending from each of the bars 6, 6 are two pairs of parallel links 12, 12 pivoted at their upper ends to the bars 6, 6 at the points 13, 13. 14 is the container, being intended to represent any suitable melting furnace, ladle or other container. This container is provided with bars 14 rigidly secured to the sides of the body thereof, and to which the lower ends of the links 12, 12 are .pivotally connected at 15, 15, the distance between the pivots of the links 12 being the same, or approximately the same as the distance between the pivots of the links 12. 16 is a discharge spout of the container 14, having its lip 17 approximately in the plane passing through the four pivots 15, 15' and located in a vertical plane passing approximately through the axis 11 about which the forward end of the links 6, 6 rotate. The pivots 15 are far enough back from the desired axis of rotation 18 to leave ends of the rods 6, 6 are elevated the furupon the drums 4, 4' at the same rate so as to draw-the rollers 10, 10 which are normally below and out of engagement with the guide members 8, 8, up into the vertical.

guidewaysQ. After the rollers 10 are in this guideway, the container is carried by the crane 2 and trolley 3 to the desired pouring position, this being accomplished by the ordinary operation of a traveling crane, which is moved so as to locate the spout 16 in the desired relation to the mold A,whereupon the rear cables 5 are wound upon the drum 4, the drum 4-being held stationary,-

' with the result thatthecontainer 14 can be tipped through any angle up to 90, as shown in Fig. 3, or even to a greater angle. After the container has been emptied to the desired extent, the lowering of the cables 5 restores the same to the position shown in Fig-1, whereupon the crane can be operated to carry the crucible to any point desired. l/Vhen the container is lowered until the rollers 10 are outof engagement with their guides 8, 8 and the container rests upon the floor, the cables 5, 5 can be detached from thebars 6, 6 and the'crane used to lift, convey and tilt another furnace or container in a similar manner.

Referring to the modification shown in Figs. 4, 5 and 6, the container in this instance represents a gas heated furnace contaming a crucible. In this modification the bridge-crane is replaced by'a car .20 upon which the container 21 is supportedfrom beneath instead o-f from above; In. order to accomplish this the car is provided with a support 22 to which are pivotally connected at23, 23 bars 24,24. Pivotally connected to-these bars at 25, 25 are links 26, 26 whose upper ends are connected to the container at V 27 27,'and' whose lower ends are provided with extensions 28, 28, which at 29, 29 are connected to links 30, 30 pivoted at 31, 31 to the support 22, the distances between the pivots 23, 23 and 25,25 being equal to the distances between the pivots'29, 29 and 31,

31, and the distances between the pivots 25, 25 and'29, 29 being equal to the distances between the pivots 23, 23 and 31, 31. Connected to the rear ends of the bars 24, 24

at 32, 32 are twoother links 33, whose upper ends are-connected at 34 to the container, the

distances between the pivots 32 and 34 being I equal to the distances between the pivots 2:")

and 27. To the rear end of the bars 24 are connected cables 35 which pass over sheaves 36 to afdrum 37 so that by winding up the cable upon the drum the rear end of the bars24, together with the rear end of the container 21 can be lifted from the position shown in Fig. 4 to the position shown in Fig. 6. In this case also the container is provided witha discharge spout 38 whose discharge lip is adjacent to a desired axis of rotation 39 indicated by the intersection of the upper dot-dash linesin Fig. 6, and the plane passing through the'pivots 2'T and passes through that desired axis of rotation.

This desired axis of rotation also lies in a vertical plane passing through the pivots 23 and 31, the result being that as the rear ends ofthe bars 24 are raised, the container is rotated about that desired axis of rotation. By these means also the container can be rotated about a desired axis although there are no trunnions in line with said axis.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit said container atone end, and a bar pivot ally connecting the other ends of said links,

1 a bearing on said bar in frontof said links and in a plane substantially parallel to said links and passing approximately through said lip, means for holding said bearing in 1 said plane, and means for lifting the rear thereof or the scope of the appended claims.
