The invention comprehends a furnace top Whichmay be shipped in knockd'ovvn form and which maybe quickly set'upwvhere the furnace is to be erected i r a The invention further comprehen-ds a fun nace top having a'sand rail which may; be

quickly adjusted in position and which will rail for furnace'tops which may be shipped in knockdown form, theoonstruoti'on being such that the sand rail'lmay be qu ckly set The invention furthermore comprehends a furnace top having lateral outlets and a top member, the sides oiiwhich diverge upwardly :i'romaeentral point toipositions above the iateral outlets.

lhe invention furthermore comprehendsf a top member for furnaces which diverges upwardly and which hasfa sand rail; thetop member and sand rail serving to support sand on the furnace toincrease the heat effioi icy of the furnace, the top member and the sand rail having'a constructioii "which makes it possible to erect the furnace top and with a cut-away portion, the sides of the top member at the cut-away portion diverging outwardly and there being interlocking members on the top member adjacent its cutaway portion, the top member normally assuming an inverted conlcal shape with lts periphery dlsposed 1n a groove 1n a rall member.

Additional objectsof the invention will appear in the following specification in which the preferred form of the invention is described. V a

By referring to the drawingsit'will beseen thatthe toplof'the furnace is constructed of lustrated in Figurefi of the drawings; each of these sections 10 having cuts 11 with stamped-up portions 12 adjacent the cuts, the said stamped-up portions serving as oneset a plurality of sections 10,:Whih are bestilof the'locking members for the sections 10.

Thepther edges of the sections are bent back at" 13,-" formiiig members 141' which; are

"disposed close" to the body of th e se'ctions l0, the members 14"'6Xt611dl11g outwardly at 15 r of the "sections 10 to the positions 17}, where they arebent inwardly and again parallel with the body of the'sections 10 to form engagingedges 18. V It will'be understood by referring to Figure 49f theidrawings, that the stamped-up portions 12 formiiigthe locking memberspass between the engaging edges 18 and the memlfbersfl l on an adjacent section 10, so that the 1 stamped up ortions 121 forining locking members willengagethe edges 18 to obtaina 'firm'locking means to hold thesections 10in and at'16 s'ubstantially'parallelwiththe body gether the rail member 21 is preferably disposed in position, this rail member 21 being preferably in one piece with a groove 22 and a sand rail 23 extending above the groove. A top member 24 is provided, this top member 24 having a cut-away portion 25, the sides of which diverge outwardly from the central portion 26, there being a stamped-up portion 27 on the top member 24 at one side of this cut-away portion 25 and there being a looking member 28 at the other side of the cutaway portion 25.

This locking member 28, as best illustrated in Figure 8 of the drawings, is secured to the top member 24 at the side 29 of the cut-away portion by bending the locking member 28 around the said side 29 of the cutaway portion and making oblique indentures 30 which press inwardly the locking member 28, together with the top member 24 at its cutaway portion, the locking member 28 having a bent portion 31 with a bent edge 32 for engaging the locking member formed by the stamped-up portion 27. It will be understood that when this top member 24 is bent in conical shape the locking member formed by the stamped-up portion 27 may be pressed into locking engagement with the edge 32 of the locking member 28 to secure the top member 24 in conical shape, this top member 24 in conical form being inverted and having its periphery 33 disposed in the groove 22 in the rail member 21 when the ends 34 of the rail member 21 are secured together by means of bolts 35 which are disposed through orifices in lugs 36 which are secured to the ends 34 of the rail member. With this construction the topmember 24 is securely held in place relatively to the rail member 21 and the rail member is secured in permanent form for use in the erection of the top of the furnace.

The rail member 21 withits top member 24 having been set up inthe manner set forth, the bottom 37 ofthe rail member 21 is disposed within the top 38 of the sections 10 which are then secured together in the manner described, the open ends of the sections 10 being then secured together by means of bolts 41, which are disposed in openings in lugs 40 which are secured to the ends of the sections 10.

In this manner the rail member is set up from the knockdown parts and is secured in position at the top of the sections 10, these sections 10 being secured together in the manner set forth, the bottoms of the sections 10 being normally disposed within the walls of the body 20 of the furnace.

As illustrated in Figure 3 of the drawings, the sides of the top member 24 diverge upwardly from a central point to the periphery 33 of the top member which is disposed in the groove 22 of the rail member21.

lVhat is claimed is: r

1. In a furnace top, a horizontally disposed circular rail member having a central opening and a groove extending radially from the central opening, the rail member having a sand rail extending above the groove, and a top member havinga circular periphery disposed to close the central open- .ing and having its periphery normally disposed in the groove.

2. A furnace having a body portion with a sand rail around a central opening, there being abead below the sand rail, the bead extending radially from the central opening and-a top member disposed to close the central opening with its periphery disposed in the bead.

3. A furnace having a body portion with a sand rail around a central opening, there be ing a bead below the sand rail which extends radially from the central opening, and an inverted conical top member disposed to close the central opening with its periphery extending into the head.

4. A furnace having a body portion comprising an outwardly extending bead and having a portion projected upwardly above the bead to form a sand rail, and a member for closing the top of the body disposed with its periphery in the bead.

5. A furnace having a body portion com prising an outwardly extending bead and projecting upwardly above the head to form a sand rail, and a member for closing the top of the body, the member diverging upwardly from a central point with its periphery disposed in the bead.

6. In a furnace top, a horizontally disposed. rail member having transverse ends, the rail member extending outwardly and inwardly from end to end to form a bead, means to se- 7 cure the ends of the rail member adjacent each other, and a top member disposed within the rail member with its periphery disposed in the bead.
