Specification of Letters Patent.
Patented Dee. I2, IQIti;
Application filed May 24, 1916. Serial No. 99,605.
.molds for casting steel ingots and especially to the sink heads or feeders of such molds, but my improvements may be employed in connection with molds for other kinds of castin In the most improved form of ingot mold provision is made for conserving the; heat of the molten metal at its upper portlon and for promoting the cooling of the lower portion of the ingot or casting and my improvements are especially intended for use in connection with such molds although they may be used in connection with molds of other designs.
In order to accomplish the results above mentioned it has been customary to make the mold walls thicker in the lower portion of the mold and relatively thin in the upper portion thereof and it has also been customary to accomplish a similar result by providing the mold with what 1s called a sink head or feeder which is so constructed 'as to conserve the heat of the molten metal at the upper portion of the ingot until the lower portion of the ingot has solidified, the molten metal in the feeder gradually descending and filling the pipe or cavity in the ingot which gradually disappears in the feeder when the solidification is complete.
Heretofore some difficulty has been encountered in properly centering the sink head or feeder on the mold in order that the cavity of the feeder shall properly register with the cavit -of the mold, and the primary object 0 my invention is to provide means for automatically centering the sink head while it is being lowered onto the mold.
Inasmuch as the mold is quite heavy and has to be moved from place to place it is usually provided with what are called lifting lugs and often these lugs are arranged on opposite sides of the upper portion of the mold. The sink head is also heavy and is provided with similar lifting lugs.
My invention may be embodied in several ways, for instance, the sink head may be formed with downwardly projecting lugs having inclined or beveled faces next the mold so disposed that when the sink head is lowered the inclined or beveled faces of the lugscome in contact with the top outer edges of the mold and cause the sink head to move laterally to a sufficient extent to properly center it. Any suitable number of lugs may be provided on the sink head for this purpose or a continuous downwardly projecting flange would accomplish the same result. Where the mold is provided at its upper end with lifting lugs the sink head may be formed with downwardly projecting lugs which may have inclined inner faces like those above described and which have also inclined or beveled sides adapted to engage the opposite sides of the lifting lugs in such manner as to properly center the feeder.
In the accompanying drawings, Figure 1 shows a vertical central section through an ingot mold and feeder or sink head embodying my improvements. Fig. 2 is a detail view in elevation showing how the lugs on the feeder engage the lifting lugs. Fig. 3 is a similar view of a slightly modified construction.
The mold A may be of any suitable construction but preferably it is what is known be a very serviceable feature in this class of molds.
The feeder D may, so far as my invention is concerned, be formed in various ways, but preferably it comprises a metallic shell or casing (l lined with refractory material d. The feeder is provided with lifting lugs d as usual and it is also provided with means for centering it on the mold. Good results for this purpose may be obtained by providing the feeder with downwardly projecting lugs 3 which are beveled or inclined on their inner faces next the mold as clearly shown, Any suitable number of lugs of this character may be used. When the feeder is .loivered if it is not properly centered the inclined inner faces of the lugs will engage the edge of the mold and the feeder will be shifted laterally to a sufficient extent to center it. Where the mold is formed with lifting lugs w near its top the lugs 1 may be made to engage the lifting lugs in the manner shown in Figs. 2 and I"). In this case the lugs 3 are arranged in pairs so as to engage opposite sides of the lifting lugs and the lower ends of the lugs may be rounded as indicated in Fig. 5, but they are preferably decidedly inclined or beveled as indicated in Fig. 2. In this way, experience has demonstrated, the feeder may be very quickly and automatically centered on the mold while it is being lowered.
I claim as my invention 1. An ingot mold formed with lifting lugs and a feeder formed with downwardly extending centering lugs engaging said lifting lugs.
2. An ingot mold formed with lifting lugs and a feeder formed with downwardly extending centering lugs engaging opposite sides of the lifting lugs.
, 3. An ingot mold formed with lifting lugs and a feeder formed with downwardly extending centering lugs having inclined sides engaging opposite sides of the lifting lugs.
4. An ingot mold formed with lifting lugs and a feeder having downwardly extending centering lugs formed with inclined or beveled inner faces engaging the mold walls and with beveled sides engaging the lugs.
In testimony whereof, I have hereunto subscribed my name.
