FEEDER FOR INGOT HOLDS.

Application filed. June 13, 1923. Serial No. 646,086.

The object of our invention is to provide an extensible feeder for ingot molds having all of the advantages of the solid or onepiece feeder to prevent seams and holes known as piping and also reduce segregation to a minimum.

Another object of our invention is to provide an extensible feeder whereb the distance the feeder extends above themold may.

be readily varied and whereby the length of the ingot can be made greater or less in the same size mold.

A further object of our invention is to provide an extensible feeder inwhich an number of sections can be placed upon eac other to build the feeder up at the same time holdin them against lateral movement -'n proper a linement.

A still further object of our invention is to provide an extensible feeder for ingot molds in which the sections are made precisely alike and interchangeable and at the same time provide a cheap and efiective structure having certain details and combination of parts hereinafter more fully "set forth.

Referring now to the-drawings, 1 repre- 85 sents the ingot mold which is of the usual construction and needs no further description. Arranged within the upper end of the mold is the main body portion 2 of the feeder which has arranged on its outer E0 periphery a number of ribs 3, which are adapted to engage the upper end of the mold and hold the feeder Within the upper end of the mold. The upper edge of the main body portion 2 of the feeder at opposlte 95 sides is provided with the upwardly extending lugs at and 5 having their inner faces beveled, as indicated at 6. The additional section 7 has its lower face provided with corresponding recesses 8 adapted to receive 1% the lugs t and 5 of the bod portion 2 and owing to the bevel thereo the section 7 will center itself upon the body portion with their inner faces flush. The upper edge of the section 7 is provided with lugs 9 and 10 m5 constructed exactly the same as the lugs 4 and 5 carried by the body portion 2. The sections 11 and 12 are constructed exactly. like the section 7 and thus it will be seen that any number of these sections can be 1m placed one upon the other to build the feeder up to the proper height desired. In the form shown in Figure 3 the same reference numerals indicate like parts corresponding to Figure 2. A strengthening band 13 is arranged around the outside of the sections to prevent the pressure of the metal from breaking and separating the sections.

In Figure 4 the body portion 2 of the feeder is provided at its upper edge with the wedge-shaped annular rib 14 adapted to enter the corresponding recess 15 in the lower face of the section 16. The upper edge of the section 16 is provided with an annular rib 17 the same shape as the rib 14 and adapted to enter a recess in the section 18. While I have shown but two sections upon the main body portion, any desired number of sections can be placed thereon to extend the feeder.

In Figure 5 the main body portion 2 at proper intervals around its upper edge is provided with pins 19 adapted to enter recesses 20 in the section 21 and thus hold the. section 21 against lateral movement on the main body portion. The upper edge of the section 21% is provided with a pin 22 adapted to enter the recess in the section 23. In Figure 5 the

sections

21 and 23 are of different. height so that the feeder can be built up to the desired height.

In Figure 6 the main body portion 2 of the feeder is provided at its upper edge with lugs 24 having the beveled faces 25 terminating in horizontal faces 26 which enter grooves 27 of corresponding shape in the lower edge of the section 28. The upper edge of the section 28 is provided with lugs 29 corresponding in shape with the lugs 24 and adapted to enter recesses in the section 30.

In Figure 7 the main body portion 2 has its upper edge beveled inwardly, as indicated at 31, and the section 32 has its lower edge beveled, as indicated at 33, to correspond therewith whereby the section 32 centers itself upon the main body portion of the feeder and is held against lateral movement thereon.

In Figure 8 the main body portion 2 of the feeder has its upper edge beveled, as indicated at 34, and the lower end of the section 35 is correspondingly beveled to fit the same and hold the section 35 on the body portion against lateral movement.- The upper edge of the section 35 is beveled inwardly, as indicated at 36, so as to receive the lower end of the section 37.

In Figure 9 the main body portion 2 of the feeder is beveled, as indicated at 38, in the reverse direction to that in Figures 7 and 8 and the section 39 has its lower end 40 beveled to correspond therewith.

In Figure 10 the main body portion 2 of the feeder has its upper end beveled, as indicated at 41, the same as shown in Figure 9. The section 42 has its lower end beveled as indicated at 43 to correspondtherewith and its upper end beveled, as indicated at 44, to correspond with the bevel of the lower end of the section 45.

Figure 11 shows the main body portion 2 of the feeder having an annular recess 46 forming a stepped upper end and the section 47 provided with an annular projection 48 entering the recess. The upper end of the section 47, is provided with an annular recess 49 receiving the projection 50 of the section. 51 whereby the sections are interlocked upon the body portion of the feeder or upon each other in their proper position with the inner walls flush with each other.

Figure 12 shows the upper end of the main body portion 2 of the feeder provided with an off-set annular flange 52 forming the annular seat 53 adapted to receive the lower end of the section 54 with their inner walls flush. The upper end of the section 54 is provided with an off-setannular flange 55 forming a recess for the section 56 whereby any desired number of sections constructed exactly alike may be placed one upon the Other.

In Figure 13 the main body portion 2 of the feeder is provided with a. semi-circular annular groove 57in its upper edge adapted to receive the correspondingly shaped lower edge 58 of the section 59. The upper end of the section 59 is provided with an annular recess 60 for receiving the section 61.

In Figure 14, instead of having the upper edge of the main body portion 2 of the feeder provided with an annular recess, it is provided with a semicircular curved face 62 adapted to receive a correspondingly shaped groove 63 in the lower end of the section 64. The upper edge of the section 64 is provided with a semicircular face 65 adapted to enter the groove of the section 66.

In Fi re 15 the projections 67 are constructed exactly like those shown in Figure 2 of the drawings but instead of having two projections on opposite sides, two sides are provided with projections, while the two opposite sides are provided with correspondingly shaped recesses 68. The section 69 is likewise provided with correspondingly shaped recesses 7 0 and projections 71.

Figure 16 shows the upper end of the body portion of the feeder perfectly fiat and the section 72 having its lower edge perfectly flat and resting thereon and the same held against lateral movement by a band 73 which may be of any desired form, such as shown in one of our prior patents.

From the foregoing description it will be seen that applicants have produced a feeder which can be readily extended to form a longer or shorter feeder to increase the length of the ingot and at the same time so construct the sections that they are interchangeable.
