when placed in the mold the sections will be retained in their normal operative posi- -tions so that the usual pouring operation can takeplace and at the same tinieprovide a feeder which will prevent piping and also reduce segregation to a' Another object of our invention is to provide a feeder of this character which is provided with means forsupporting' it in the upper end of the'mold and said means also serving as means. for strengthening the feeder.` Y

Another. object of our invention is to provide a feeder having supporting means contained. in each section so that each section is independently supported on the top of the mold'.

'A further object of our invention is to provide a sectional feeder which can be asf -sembled ont of the mold and held together by a band so that the inold can fbe'shipped-i in sections and readily' assembled.l

Anothr'object of our invention is to provide a 'feeder f-uniform/ sections so that the edges thereof willit each to each without diiculty in assembling and at the same time prevent movement after assembling.A

A still further object of our invention is tp provide a feeder of this character which is provided with the e supporting and strengthening means so arranged that .a flat-band fitted to the contour of the outer periphery can be placed. around'the feeder and not interfere with the entrance of the feeder into the neck ofthe mold.

A still further objectfour invention is to rovide a simple, 'chea and. effective fee er havin certain details of structure and combination of partshereinafter more fully set forth.

'FigureflO is `a perspective view of an `'ingot mold showing a still further modified' form of our improved feeder.

Referring nowto the drawings 1 represents the ingot mold and 2 thefeeder. A s shown in the drawings the. feeder 2 is of a circular form and formed of four sections 3, 4, 5 and 6 the connection or joint between the/same being in a radial line of the vcircle so that when the four :sections are placed in the neck yof the mold they are locked together against inward movement as shown in Figure`1 of the drawings.

The outer periphery shown m each section is provided with ribs 7 and 8 the lowerI ends of which rest onthe-upper end of the. mold and whereby eaoh'section is independ- "ently supported by .the;mold. While we have shown two ribs carriedby eachv section it will be understood that any othernnmher could be'used.A l

` In Fi ures`3 and 4 we have, shown a hand 9 exten ing. around the outer periphery of the several sections and of a shape snugly 'fitting the walls of the sections and the ends of the band held together by the clamping member 10 all of which is shown and described in our Patent No. 1,481,853. 'lhe feeder bein divided in sections the abutting walls of w ich being arranged in a radial line, it will be seen that when the sections have their Walls abutting either against the ed tettoia mold or when the band 1s emplQ) them together before the feeder\is placed in the mold, the .sectiqnscannot move or colla se inwardly and are firmly 'l to et er. y

n Figure 5, the feeder 11A 1s made of fou;`

are slightly curved and are also vprovided with ribs 16 supporting the feeder in the it can be assembled and placed in the mold as a unit.

In Figures 6 and 8 we have shown a recl tangular feeder the abutting u'walls 17 of 18 made up of four which are also so cut that the sections cannot be collapsed inwardly when used in thev mold or when setup outside of the mold and held-together by a band.

In Figure 9wehave shown a tinted feeder sections 19, 20, 21, and 22 and the outer Walls of which sections being' rovided with vertically disposed rib 23 w ich is adapted to rest upon the up r edge of the mold and supporting itwit in the mold. These ribs on each side at the point of contact .with the body of the lfeeder are provided with scores`24 and 25 which weakens the ribs and 'allows the same-to be.`

broken 'ofi' when desired. Theribs intermediate their `upper and lower ends are cut away so that the band 9, to conform with the outer periphery, -may 'pass therein and whereby the band does not have to be shaped tobcorrcspond with the outer contour of the r1 s. i

In Figure 10 we have shown a shoulder feeder 26 mad'cup of four sections 27, 28, 29 and 30 cut at an angle at the corners so that when the same is placed in the mold the independent 'sections cannot move inwardly, or when the band is emplo ed aroundthe outer peri hery of the shoul er, the sections cannot. co lapse.

Having thus fully described our invention what we claim is 1. A feeder for ingot molds comprising a series of sections, the abutting -walla vthereof being so arranged as to prevent movement.

2. A feeder ,for ingot moldswcomprising a series of longitudinal sections, each section having outwardly extending independent supporting means.
