TROUGH.

Specification of Letters Patent. Patented July 4:, 1922.

Application filed September 11,1920. Serial Iva-409,563. I

To all whom z't may concern:

Be it known'that I,:Ronnn'r A. BAGNELL, a

- dling metals in molten form, suchfas may be adaptable for use in foundries and similar places to convey metal in molten form from the source of supply to the placewhere it is to be used.

The molten metal discharged from the furnace of a smelter or the like is often cast into so called pigs,-and for that purpose must be conveyed from the furnace to the pig molds. This is usually done by receiving the discharge of the furnace in a suitable ladle, transporting the ladle to the pig molds and discharging the metal into said molds. In some cases where conditions permit, the pig molds are located in close proximity to the furnace. The metal is then discharged from the furnace and allowed to run into the molds. This arrangement necessitates the location of the pig molds very close to the discharge opening of the furnace and such location is often inconvenient to other operations about the furnace.

One of the objects of this invention, therefore, is to provide a trough for conveying the molten metal from the furnace to the molds, which shall be capable of being easily assembled or dissembled, so that it may be put in place when wanted and removed when not wanted.

Another object of this invention is to provide such a trou h which, when it becomes choked with solidified metal, slag or the like, may be readily cleaned of such obstructions.

Another object is to provide such a trough which shall be simple in construction, cheap to manufacture and simple to handle.

Further objects will appear from the following description taken in connection with the accompanying drawing, in which:

Figure 1 represents a plan view of a trough embodying this invention;

Figure 2 represents a side elevation of a portion of the trough;

Figure 3 is a section on line 3-3 of Figure 2; and

F igLlTGl is a section on lined-4 of Figure 2.

Referring now to. the accompanying drawing 1. designatesa base which may be of cast .iron or-similar material; .2 isv a connecting link which may lie-embedded permanently within the base'l or. may be simply passed through an aperture therein; 3 designatesithe sides. of the trough which may be of cast iron, boiler plate or other suitable material. The side plates 3 are provided with apertures 4, through which the ends of the link 2 may be passed after which wedges 5 may be forced in between the ends of the links 2 and the plates 3 so as to fix those plates securely in place on the base 1. A trough is thus formed which is very rugged, adapted to be easily assembled or dissembled.

The trough may be made in sections,in one of which the side plates 3 may be allowed to extend beyond the base 1, and in the other, the base 1 is allowed to extend beyond the side plates so as to form a dovetail joint as shown at 6 in Figure 1.

The upper end 7 of the trough, which should be first lined with refractory material 8, may be placed adjacent the iron notch of the furnace or under the discharge opening of the ladle so as to receive the metal therefrom. The lower or discharge end 9 may be placed adjacent the molds which are indicated in Figure 1 by the dotted lines 10. These molds may be arranged as a series of individual units mounted on a conveyor, which may be made to pass underneath the end 9 of the trough in such a way that the trough will discharge into and fill said molds. The trough, as a whole, should of course be given a sufli cient incline to cause the metal to run freely from the end 7 to the end 9 and to discharge into the molds.

If the trough should become choked by the solidification of metal, slag or the like, it is an easy matter to dissemble the trough transversely by removing the wedges 5 and knocking off the side plates 3 after which the obstruction may be removed with hammers or other means.

It will be seen that the invention accomplishes its objects. A trough is provided which is adapted to convey molten metal in a convenient manner from the source of supply to the place of utilization, It is adapted to be easily dissembled so as to be out of the Way to make room for other operations and is adapted to be quickly and easily cleared of obstructions.

It is obvious that various changes may be made in the details of construction Without departing from the spirit of thisinvention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

Having thus described the invention, What is claimed is:

1. A trough for conducting molten metal, comprising, a base, a pair of detachable side members, and means for connecting J said base and said members.

2. A trough for conducting molten metal, comprising, a base, a pair of detachable side members, and a'link adapted to connect said base and said members. i Y

3. A trough for conductingmolten metal, comprising, a base, a pair of detachable side members, and a link embedded in said base and adapted to connect said base and said members.

and said members, apertures in said mem-.

bers adapted to engage said link, and means engaging said llnk adapted to secure sald members in place.

6. A trough for conducting molten metal, 1

comprising, a base, a pair of detachable side members, a link adapted to connect said base and said members,apertureg in said members adapted to engage said link, and a Wedge engaging said link adapted to secure said members in place.

In testimony whereof I a'ffix my signature this 16 day of July, 1920.-

ROBERT AQBAGNELL.
