ee'li andi' Wire.I (lompan'y ofY a. corporatioir ofv New;v Jerseir xpp-nennen December zo, 1911;, serrer No. 4233561- scisime.. (ci. zasmfr This'. invention relates. to bases.' or supporting means'` for furnaces and?, particul'arly,. to' an'. imp'roved base or supporting means for metallurgi cal furnaces, suol-ias box. annealing furnaces.. and.- the like.

Various types of bases. have.beensuggestedand used for supporting the charge. in metallurgical furnaces. While. such bases usually satisfactorily supported the charge in the furnacei they'weref not designedv so as to. permit theI heating gases-toi circulate in and' around the lower portion of. the.- charge toY satisfactorily heatv the same.. Some bases suggested' were designed so a-stopermit thei gases to pass only in. one direction through the base and. around thecharge therein., but such bases did not'permi't maximum circulation of theI gases andl were not entirely satisfactory.

In the presentv invention,1 therey is. provided a-v bas'e for metallurgical furnaces whichl is so con4 structed' that the heating gasesy pass in. botha; longitudinal and transverse direction through the base", and. up through the lower portion yof the:

. charge, thereby eliminating the above named diseA advantages.

l Accordingly. it Lis the general. obectnI thefpres` ent invention. to provide animprovedbase, for useA with metallurgical furnaces and the like, which is so constructed andl arranged that the heating gases are permitted to pass both longitudinally and transversely through the base so that the lower portion of the charge resting thereon is eiliciently and effectively heated.

It is another object of the invention to provide an improved base for use with metallurgical furnaces and the like which is simple and inexpensive in its construction and, at the same time, a base which is strong and rugged.

It is a further object of the invention to provide an improved base for use with metallurgical furnaces and the like whereby the heating gases .pass entirely underneath and around thelower portion of the charge so as to rapidly penetrate the same, thereby heating the charge to the desired temperature in a minimum amount of time.

Various other objects and advantages oflthis invention will become more apparentduring'the course of the following specication and will be particularly pointed out in the appended claims.

In the accompanying drawings there is shown, for the purpose of illustration, one embodiment which my invention may assume in practice.

In these drawings:

Figure 1 is a plan view of the improved base of my invention;

Figure. 2r is. an. enr/non of. one. side of the base asshowniniFigure 1';

Figureu 3l isy ani elevation of another side. of' my improved b'asesi'rnilarto Figure. 2.;A

Figure 4 is *ay section-taken on line IV-IV of Figure,1';'and' i Figure 5'i's a section taken. on line V-V ofFigure'l.

Referring more particularly to the drawings, the.r improved' base of' my invention comprises preferably` a cast steel rectangular-shaped body member 2 having a top 3,A sid'e and end walls 4;

and a bottom 5'; There is arranged' between the side` and en'dwalls 4' preferably a pluralityL of' spaced apart longitudinally and transversely extending rib-like portions 6 which are connected together 'to yform an integral body unit. That is; longitudinally and' transversely extending riblike portions `l. are arrangedsubstantially perpendicularf to' each other and' are spaced apart, from eachA othenx There arranged, through each of the side andV end walls 4` andthe rib-like portions E', a plurality of openings 'l so as to` provide a., plurality-of passageways through the body member yextending `both longitudinally and transversely thereof and being interconnected with each other.v That is,l the longitudinally extending, rib-like portions BIare spaced apart. with the )transversely extending rib-like portions having la hole arranged therethrough opposite the space between the longitudinally extending rib-like portions so as to provide a passageway therebetweenwhich extends throughout the length of the body member and the transversely extending rib-like portions are spaced apart with the longitudinally extending rib-like portions having an opening ar-' ranged therethrough opposite the space between the transversely extending rib-like portions so as to provide a passageway between the transversely extending portions throughout-the width of the body member. It will thus be sen that the'passageways between the longitudinally ex'- tending rib-like portions and the transversely extending rib-like portions are substantially perpendicular to each other and are all interconnected `with each other.

In the top 3 of the body member 2 between each of the rib-like portions 6 there is provided an opening 'I which communicates with the transversely and longitudinally `extending passageways arranged therebelow between the transversely and longitudinally extending rib-like portions. There is arranged in the bottom 4 of the base preferably a plurality of larger openings 8 which also communicate with both the longi 'of my invention is placed in the furnace Withwhich it is adapted to be used with the bottom 5 thereof resting on the bottom of the furnace. The charge is adapted to be disposed on the top 3 of the base.

As a result of my invention, it will be seen that there is provided not only a base whereby the heating gases in the furnace may' circulate both longitudinally and transversely of the base in a horizontal plane, but also a base whereby the' gases may 'circulate from the bottom through the top of the base in substantially a vertical plane. Accordingly, it will be seen that by providing such a construction, the heating gases may circulate up through and around the base and the lower portion of the charge positioned thereon, thereby effectively heating the lower portion of the charge with the least amount of heat input.

While I have shown and described one specific embodiment of my invention, it will'be understood that this embodiment is merely for the purpose of illustration and description and that various other forms may be devised within the scope of my invention, as defined inthe appended claims.

I claim:

1. A removable base for metallurgical `furnaces and the like comprising a body member having top, side, end and bottom walls so as to provide a box-like structure, a plurality of longitudinally extending spaced rib-like portions arranged within said body member throughout the length thereof, a plurality of similar laterally extending spaced rib-like portions arranged within said body member extending throughout the width thereof and disposed substantially perpendicular to said'longitudinally extending rib-like portions, both of said longitudinally and laterally extending rib-like portions extending the height of the body member and intersecting each other, an opening arranged in each of said side walls and each of said longitudinally extending rib-like portions between adjacent laterally extending rib-like portions so as to provide apassageway throughout the width of the body member between each of said laterally extending rib-like portions, a similar opening arranged in each of said end walls and each of said laterally extending rib-like portions between adjacent longitudinally extending rib-like portions so as to provide a passageway throughout the length of the body member between each of said longitudinally extending rib-like portions whereby a plurality of interconnected passageways are provided throughout both the length and width of the .body member so as to provide a checker-like arrangement of passageways whereby heating gases may circulate into and around through all of the openings and passageways of the body member.

2. A removable base for metallurgical furnaces and the like, as dened in claim l, including an opening arranged' in the top wall between adjacent longitudinally and laterally extending riblike portions communicating with the respective passageways arranged therebelow -in the body memberso as to provide a checker-like arrangement of openings in said top wall whereby the heating gases may circulate into and around through all of the passageways and up through the openings in the top of said body member.

3. A removable base for metallurgical furnaces and the like, vas defined in claim l, including an opening arranged in the top wall between adjacentlongitudinally and laterally extending riblike portions communicating with the respective passageways arranged therebelow in the body member so as to provide a checker-like arrangement of openings in said top wall, and a plurality of openings arranged in the bottom wall of said body member communicating with the passageways varranged thereabove between the laterally and longitudinally extending rib-like portions whereby the heating gases may circulate into and around through all of the passageways and up through the openings in the top of, said body member.
